@209seancoatello There is no point to get a throttle body spacer in 2006-2012 chevys. There is NO HP gain all, all it does it make it sound a little louder and maybe a little more throttle response but you can not notice it.
tire size helps i can not get my truck to spin 285/75/16s but i put some stock 05 chevy wheels and tires on it and it lit em up like they were nothin i gota vid check it out
@rekjavicxxx, Could you do a video on how to stop em? I read on the internet there is alot of creaking sounds coming from the door, perhaps weather stripping? I don't trust the dealers.
the port and polish of the throttle body is not a significant mod unless a cold air pipe high flow exhaust and a tune change is done first and even then you looking at 3hp top on a naturally aspirated 5.3l if using a power adder then maybe more but quite frankly before doing that i would add taylor 50ohm plug wires and E3 plugs cause you get more hp and fuel economy
only reason i can think of it losing power is by having the smaller sized tires on it acted like giving the truck a set of higher gears. example with the 33's on say it has 4.10 gears. and with the smaller tires it made it seem like it had 4.56's
@rekjavicxxx Lol or the tires that most likely weight 2 1/2 times more than that of the corvette tire made the hp go down lol common sence am i right ?
@rekjavicxxx , Do you have any problems with the driver side door creaking/ dashboard rattle. Cuz I'm arguing this thing with Chevy and my dealer now cuz the friggen door keeps on creaking as the body flexes (like doing a simple 90 degree right or left turn.) and my Dash rattles and it gets quiet when i open the top glove compartment.
i wanna p&p my throttle body and the heads just dont have the time. have you thought about doing your heads? i did and exhaust video from cold start today check it out!
I just ran into this issue the other day with my truck on the dyno. I used to have 265/65 18 and made 343 rwhp and 380 rwtq. With 32 11.50 18 it made 306 rwhp and 365 rwtq. Yet at the track it has been running 5 to 7 tenths of a second faster in the 1/8th mile.
@ledbetterbrothers Hmm....that's strange. Mine ran slower with the larger tires. Check out my other video: "2007 Silverado on 20's vs. Silverado DRAG RACING Tire Comparison"
@rekjavicxxx I just checked out that video. You have great videos by the way. All that I can think of is I'm spinning less with the bigger tires, helping my 60ft time.
how much were the Gibson headers? And what would you rate the difficulty installing them? Also i had the 57 series K&N that my buddy gave me, i sold it and bought the Air raid that was similar and noticed much more hp than the K&N, no clue why, basically the same intake.
@z71cory Well, considering I took them to an exhaust shop to install, I wouldn't be able to tell ya firsthand how difficult that would be, I do know it doesn't appear to be a ridiculous task. I purchased the headers, had them installed along with full exhaust for $1100.
Since that body style was so new, the long tubes weren't available at that time. I would recommend you go with LT's now since they are available.
@rekjavicxxx i have a custom exhaust(true dual) and i dont think the long tubes will fit. They are better though, the less bends the better the flow. Mines only a 2003. Have you replaced your spark plugs? I got some E3 ones and i noticed about 10hp gain and now im running 18mpg in the city when i was running 16mpg lol
@z71cory Hmm....that's interesting. I've only got about 44k miles on the truck, so haven't thought about doing the plugs yet. I may look into that though! :)
@z71cory Hey, I have a question about your plug's. I bought bosch platinum irridium's for my 08 silverado and they were junk. Truck would idle rough when it first started up and I pulled the plugs off and theywould have some dampness from fuel on em. I put ac delco irridium's and never had a problem again. The E3 spark plug's, are they as good as you say they are? I wanna try em in my truck. I change out the plugs and wires once a year and might get the e3's. Please get back to me.
@CSXtrackworker The e3's worked great on mine, i changed them once i hit 90k miles and have had them for 3k miles, so far noticed a pretty good change in mpg about 2 or 3 mpg better. My buddy tried Acdelco from autozone and said they worked great, so I would say either or would be best.
@pdub4271991 I did all the exhaust work at once, so dunno if "just" the headers had a huge effect, but I do know it has an amazing sound now! :) Love it!
I find this strange, not the fact the shorter tires made a difference, You said Corvette take offs, Corvette have a 5x43/4 bolt patteren. How did you get them on that 07 Chevy Truck which has 6 lug bolt patteren ?
@remowil55 Takeoff tires....Those are my stock 17" wheels that came off the truck from the factory. Had a buddy donate the tires to me from a vette, so it made for a cool comparison :)
@PedroSantana12345678 I did the intake, headers, exhaust and tune all at the same time, so I dunno how much just the intake gave. There are detailed specs on K&N's website. Overall I got like 42RWHP over stock...
hey i polished my throttle body but now my rpm's r high in park did u have the same problem? and if so how did u fix that? i have a 08 silverado 4.8 .thnx
@kfx700dirtking That will be something you have to adjust in your tune. Get a tuner shop to flash ya a custom tune in there, then adjust accordingly....
hey man sick truck!!! I have a 2003 z71 with the 5.3 and so far i only have the superchips cortex programmer and a flowmaster dual exhaust and it did help some but im looking for more. Im thinking about a k&n cai and some headers. Any suggestions?? how did those Gibson headers do?
Sounds like you've got a good project on your hands. I'd definitely get the K&N CAI. Get the model # then hop on Ebay...you'll get it for half of retail usually. As far as the headers, I'd go with long tubes if I were you. I could only get the shorties at the time since the body style was so new. They sound great but just didn't add a ton of HP.
The tire comparison is bullshit. You used tires with a difference of almost 8 inches. HP/TQ loss to weight is minimal, it is the fact that you effectively RAISED your gear ratio, decreasing the multiplying effect of your differential. The same vehicle with 4.10 gears will put out bigger numbers than 3.55 gears.
@xevi8907 Oh yeah?! Well, explain the 16.2 quarter mile with the 33's compared to the 15.4 run with those 17" radials. Check out the recent tire comparison video. Tells the story for itself....
A shorter tire results in better power/tq multiplication...The more power and torque you lay down, the faster you accelerate=faster times @rekjavicxxx
@desidegollado Yes, you can do that to any TB. Depending on how the TB is designed, depends on the gains you receive. If you can really take a lot of the edges and obstruction out of the TB, you'll receive greater gains....Prolly 3-4HP with this one...
cool so my 2002 5.3 silverado it sits on 20 inch LTZ stocks with a 275/45 tire and throtle body spacer superchips flash pack and k&n cai and eaton locker. how much you think im loosing compared to the 16 inch stocks? and how much rwhp you think i have?
@JRG0921 It'd be tough to just speculate, but probably not near as much as this comparison. Those 20" stock tires aren't near as heavy as those Coopers. You've probably only got about 15RWHP loss over the stock 16" tires....
WOW I knew tire weight/size took away from performance but i had no ideal it was that much. I guess this means with the fact that my 4.3 makes 200 HP at the crank it would make 110-120 real HP with 20 inch wheels on it. Yikes!
@JRG0921 I believe the lower level 5.3's only make 295HP at the crank and are linked to GM tried and true 4-speed auto. more drive-train loss.{guess those have only about 255HP tot the wheels}.
So u ground out the inside and outside of the throttle body? Could this be done on the 4.3L think? DId u set the flap open and grind away where that would reset at the starting position?
No, K&N will not void the manufacturers warranty. It's a simple bolt-on, so no worry of voiding the warranty. K&N even backs up that claim with their own guarantee...
hey whats up man. i had a qwestion why did you p&p your thorttle body instead of going an buying a aftermarket one??? is it the same thing as a aftermarket. the only reason i ask cuz im getting ready to buy a bbk tb for my f150 and would rather p&p then waste 3 bills lol
actully i have the BBK 75mm throttle body l understand 300bucks is alot but it wakes your 4.6 or 5.4 to the point its just as snappy as a GM 5.7 vortec the best bang for the buck.....on another note the f-150 intake AND MASS AIR FLOW upgraded sensor l have all 3 about 700bucks are beyond awsome l'm 12lift 33' tires
really. i heard with the jet mass airflow sensor you have to get a custom tune? so far i got a afe intake and a borla cat-back. i dont know were to go next i wanted a tuner but im trying to see what else i out there. did you ever get your truck on a dyno?
I don't recall the grit. There were two separate wheels....rough to start and then fine to finish. Do some looking online and I bet you'll find some good solid insight on that one...
It was a cutoff grinder with a couple of different texture brushes. First is more of a grinder, then you use a less course wheel. A couple of different polishing compounds are used as well...
I'll put it in simple terms, so even you simple minds can understand it: when you change rim/tire size, you change the effective gear ratio, which means the roller mass will achieve an equivalent RPM at a higher/lower engine RPM. The power measurement is based on this rate-of-change, therefore, the faster/slower rate will render a higher/lower whp value. It's a shortcoming of inertial dynos. The truck did NOT lose 41whp, the dyno just didn't compensate for the gearing change.
I'd like to see you rationalize your way out of losing a cash race because you had larger tires and wheels (PRODUCING THE EXACT SAME RWHP AS YOUR COMPETITOR) but somehow he beat ya to the finish....
WOW!!! Ignorance really is bliss!!! Russell218, Hooray for Chris, Grammer Knotzi, Fucktard Douchebag, whatever you call yourself! If we put a 100lb sack of shit on your back and had you run as fast as you could, you think you can run faster with or without that sack of shit on your back! From what I have gatthered from these comments you need to repeat the 7th grade. Stay in school and stay off You Tube. My channel name says it all!!!
Would I run slower with the sack? Of course. Would my legs be making less power? Absolutely not. Congratulations, you just posted an analogy that proves my point!
Read 05Silvys comment over and over and over until it sinks in! YOU LOSE HORSEPOWER UNLESS YOU HAVE GEARS TO COMPENSATE! Congragulations, your still a douche bag! My channel name says it all!
man this guy is an idiot. bigger wheels means you need more power to turn those bigger wheels than the smaller one you had before! why do i bother sometimes? lol
if he knew anything about a dyno jet dyno also he would know that there is ZERO adjustments on one....all you do it strap it down and hit start...you cant fudge a thing...it is what it is on a dynojet 224x.......LOL>.people like this just make my day cause i need a good laugh everyday!
its just common sence....there mouth they will just keep shoving it further and further down there! man i wish he was a female, i would have to get his #### if he can down his foot that good just imagine what he could do!
wow, what a moron...and he has to have 3 screen names also...LOL.....
if he knew anything he woudl know that rotating mass does make a differance.....we went from big tires and big wheels to a set of 17"s with radials on it. anyone with half a brain knows that tires size effects the RWHP reading of a dyno a ton! ...............................
Well I THOUGHT I was done here, but I just noticed your "stern advisement," which was clearly an invitation for me to return. And you know, the best part about having to create a new account every time I return - it enables me to leave another 1-star rating! I can't wait until Youtube runs the next table updates and the rating on this vid plunges.
That's fine buddy. Keep visiting my vid...my views keep rising and the comments keep accruing. That's all I'm out for with this Youtube stuff.....views and comments! Got any friends that can help rack up a few more hits for me?!?!?!
Apparently, aside from being a professor of BS, you're a professor of reverse psychology, so since I'm eating up the hits and comments, notice I've also unblocked all your bogus channels as well. Keep it coming buddy!! Keep in mind, you're perpetuating this boy!
Hooray4Chris you are a fuckin prick. You talk shit for no reason. And when you do put larger tires on your truck it does make you lose power. There is more tire to turn than what a stock tire is which means it takes more power to turn a larger mass of rubber than a small mass of rubber. Unless you have gears to compensate for the larger tires it puts more strain on your drive train because the difference in size. i know its true and its a fact. Jackass
No, that's a common misconception. It only takes more power to spin the additional mass up to speed. I've already discussed angular momentum here somewhere. But PEAK power remains unchanged. That's why installing a lighter flywheel, or lighter rods, or lighter wheels/tires doesn't affect dyno numbers. You will accellerate quicker, so track times will improve, but peak power doesn't change. So with heavier tires, you'll make the same power, just at a slightly higher RPM.
i dont understand what this dudes problem is. its right there on the video. at 4:25 40 H.P. loss. dude needs to get a hobbie besides baggin on peoples vids he can come over to my channel and ill tell him where to go and how to get there in a hurry! :~
Yeah, I hear that! I thought it was funny how kelrae01 posted that he had the ExAcT same results as I did and that guy is still trying to say it's impossible.
I'll give it to him that tire size has no bearing on HP at the crank, but that was never implied....RWHP was the focus the entire time...
My hobby is simply putting a stop to the unchecked spread of stupidity on Youtube. This clown doesn't know how to run a dynomometer, and now everyone who watches this vid actually believes that installing larger tires will reduce hp to the wheels. So suddenly common sense is out the window because this guy posts a video. It's ridiculous how stupid the average Youtube user is.
It's ridiculous how gall dern stubborn some people are! If I've blocked you three freakin times, wouldn't most folks get the point? If someone asked you to leave their restaurant for unwelcome behavior, would you keep coming back day after day, just to be asked to leave once again? What point are you proving other than the fact you're a pigheaded asshole!
And another thing - tire size has NO bearing on dyno whp. You need to fire your dyno operator. OBVIOUSLY, if putting on larger rims really made you lose 40whp, then nobody would use large rims. Fucking redneck idiots.
Dude, if you're so naive not to believe video proof positive that tire/wheel size has a bearing on WHP, then you're an absolute MoRoN! First run was with 17" wheels. I jacked the truck up IN PLACE(never moved it from dyno) and placed 20's on there and did the second pull. Unless you've done this comparison, you have no room to speak.
As regards the dyno operator, he's done more dyno pulls on vehicles (many in excess of 1000HP) that you have hairs on your brainless head!
Go to college and earn a degree in engineering as I have, then we'll talk. Learn your rotational kinematic formulas and you'll see how plainly the physics demonstrates why wheel size has NO bearing on hp. And yes, I've done the comparison many times. I frequently dyno cars on 22" drag radials which start to slip badly in 3rd gear when full boost hits, so that's when the 26" slicks go on. And ZERO change in hp. Wheel/tire size DOES NOT affect hp, it's a FACT.
I go to college everyday.....that is my place of occupation. Do you work at an institution of higher education???
Oh, and didn't I tell you to never post comments on my channel again?!?!? Apparently you should go to the college of comprehension, because when I say don't post comments on my channel, you should CoMpReHeNd the fact you should not click the "Post Comment" button on my videos.
Ah, your "place of occupation." I'll assume that you're merely referring to the physical local. Let me guess - you're a "sanitation engineer." Lol. Try to swing by the engineering building and catch a 200-level physics lecture sometime. Phys 220A is a good place to start for basic linear and rotational kinematics.
so youre saying if you put more weight in the bed of that truck that it would give the same numbers every time, because thats whats happening when you put the bigger M/T tires on it. I drive a 04 f250 6.0 with a 5 inch jones bro true dual exhaust a bully dog tuner airaid intake 35 13.50 boggers, rwhp 391, with the stock 31s i get 433 rwhp. explain that please
Efficiency is reduced slightly with heavier rims/tires due to the increase in unsprung rotational mass. This results in slower angular acceleration which slows power delivery, but PEAK power to the wheels remains unchanged. It is the same with increasing or decreasing any other piece of rotational mass (such as the flywheel) which alters acceleration, but NOT peak power. The reason for your noted hp variance was improper dyno correction (i.e. miscalculated gearing/tire size/altitude/etc.).
Apparently you don't get it! Kelrae01 reported strikingly identical readings and circumstances to what was in my vid.
Oh, and glad you figured out how to create bogus Youtube accounts so you can flame people's videos with your unsubstantiated crap. Post up some credible evidence next time Mr. Physicist!
all i want is a nice 2002 to 2005 silverado 4.8 4wd with headers cool intake exhaust and a little tune thats i want and all i need in my opinion

@PedroSantana12345678 I did the intake, headers, exhaust and tune all at the same time, so I dunno how much just the intake gave. There are detailed specs on K&N's website. Overall I got like 42RWHP over stock...

@kfx700dirtking That will be something you have to adjust in your tune. Get a tuner shop to flash ya a custom tune in there, then adjust accordingly....

hey man sick truck!!! I have a 2003 z71 with the 5.3 and so far i only have the superchips cortex programmer and a flowmaster dual exhaust and it did help some but im looking for more. Im thinking about a k&n cai and some headers. Any suggestions?? how did those Gibson headers do?
jaymcclure188 1 year ago
@jaymcclure188 Glad ya like it!! :)
Sounds like you've got a good project on your hands. I'd definitely get the K&N CAI. Get the model # then hop on Ebay...you'll get it for half of retail usually. As far as the headers, I'd go with long tubes if I were you. I could only get the shorties at the time since the body style was so new. They sound great but just didn't add a ton of HP.
rekjavicxxx 1 year ago
The tire comparison is bullshit. You used tires with a difference of almost 8 inches. HP/TQ loss to weight is minimal, it is the fact that you effectively RAISED your gear ratio, decreasing the multiplying effect of your differential. The same vehicle with 4.10 gears will put out bigger numbers than 3.55 gears.
xevi8907 1 year ago
@xevi8907 Oh yeah?! Well, explain the 16.2 quarter mile with the 33's compared to the 15.4 run with those 17" radials. Check out the recent tire comparison video. Tells the story for itself....

A shorter tire results in better power/tq multiplication...The more power and torque you lay down, the faster you accelerate=faster times @rekjavicxxx

desidegollado 1 year ago
@desidegollado Yes, you can do that to any TB. Depending on how the TB is designed, depends on the gains you receive. If you can really take a lot of the edges and obstruction out of the TB, you'll receive greater gains....Prolly 3-4HP with this one...

cool so my 2002 5.3 silverado it sits on 20 inch LTZ stocks with a 275/45 tire and throtle body spacer superchips flash pack and k&n cai and eaton locker. how much you think im loosing compared to the 16 inch stocks? and how much rwhp you think i have?
JRG0921 1 year ago
@JRG0921 It'd be tough to just speculate, but probably not near as much as this comparison. Those 20" stock tires aren't near as heavy as those Coopers. You've probably only got about 15RWHP loss over the stock 16" tires....
rekjavicxxx 1 year ago
WOW I knew tire weight/size took away from performance but i had no ideal it was that much. I guess this means with the fact that my 4.3 makes 200 HP at the crank it would make 110-120 real HP with 20 inch wheels on it. Yikes!
abram7117 1 year ago
@abram7117 Yeah, it's a pretty significant loss!!
rekjavicxxx 1 year ago

JRG0921 1 year ago
@JRG0921 Hey, thanks for checking it out...glad ya liked it!
The crank HP is 315. There is quite a bit of loss, as you can see with the tire comparison. Driveline loss is pretty significant on a truck...
rekjavicxxx 1 year ago
@JRG0921 I believe the lower level 5.3's only make 295HP at the crank and are linked to GM tried and true 4-speed auto. more drive-train loss.{guess those have only about 255HP tot the wheels}.
abram7117 1 year ago
a lot of it was actually the weight of the wheels, not the tire size. but tire size would still affect it

So u ground out the inside and outside of the throttle body? Could this be done on the 4.3L think? DId u set the flap open and grind away where that would reset at the starting position?
SnapDaddy5998 2 years ago
If you've got a throttle body, you should be able to do this. Some respond better than others according to design.
Didn't move the flap...it's basically just to channel air faster through the neck of the TB.
rekjavicxxx 2 years ago
just remove the throttle body diffuser that's built onto the flap. P&P on a 4.3 TB is useless

rekjavicxxx 2 years ago

GreyGhostZ71 2 years ago
I'll put it in simple terms, so even you simple minds can understand it: when you change rim/tire size, you change the effective gear ratio, which means the roller mass will achieve an equivalent RPM at a higher/lower engine RPM. The power measurement is based on this rate-of-change, therefore, the faster/slower rate will render a higher/lower whp value. It's a shortcoming of inertial dynos. The truck did NOT lose 41whp, the dyno just didn't compensate for the gearing change.

Hooray4Chris you are a fuckin prick. You talk shit for no reason. And when you do put larger tires on your truck it does make you lose power. There is more tire to turn than what a stock tire is which means it takes more power to turn a larger mass of rubber than a small mass of rubber. Unless you have gears to compensate for the larger tires it puts more strain on your drive train because the difference in size. i know its true and its a fact. Jackass

scotts01Z71 2 years ago
No, that's a common misconception. It only takes more power to spin the additional mass up to speed. I've already discussed angular momentum here somewhere. But PEAK power remains unchanged. That's why installing a lighter flywheel, or lighter rods, or lighter wheels/tires doesn't affect dyno numbers. You will accellerate quicker, so track times will improve, but peak power doesn't change. So with heavier tires, you'll make the same power, just at a slightly higher RPM.

And another thing - tire size has NO bearing on dyno whp. You need to fire your dyno operator. OBVIOUSLY, if putting on larger rims really made you lose 40whp, then nobody would use large rims. Fucking redneck idiots.
Russell218 2 years ago
Dude, if you're so naive not to believe video proof positive that tire/wheel size has a bearing on WHP, then you're an absolute MoRoN! First run was with 17" wheels. I jacked the truck up IN PLACE(never moved it from dyno) and placed 20's on there and did the second pull. Unless you've done this comparison, you have no room to speak.
As regards the dyno operator, he's done more dyno pulls on vehicles (many in excess of 1000HP) that you have hairs on your brainless head!
rekjavicxxx 2 years ago
Go to college and earn a degree in engineering as I have, then we'll talk. Learn your rotational kinematic formulas and you'll see how plainly the physics demonstrates why wheel size has NO bearing on hp. And yes, I've done the comparison many times. I frequently dyno cars on 22" drag radials which start to slip badly in 3rd gear when full boost hits, so that's when the 26" slicks go on. And ZERO change in hp. Wheel/tire size DOES NOT affect hp, it's a FACT.

kelrae01 2 years ago
Efficiency is reduced slightly with heavier rims/tires due to the increase in unsprung rotational mass. This results in slower angular acceleration which slows power delivery, but PEAK power to the wheels remains unchanged. It is the same with increasing or decreasing any other piece of rotational mass (such as the flywheel) which alters acceleration, but NOT peak power. The reason for your noted hp variance was improper dyno correction (i.e. miscalculated gearing/tire size/altitude/etc.).
Hooray4JuniorCollege 2 years ago
Apparently you don't get it! Kelrae01 reported strikingly identical readings and circumstances to what was in my vid.
