hey man, what about your seat? doesnt it get heated ? is this healthy or unhealthy for your bike ? i wanna do the same with my r1, but need to ask first. thanks :)
im pretty sure this wont mess up the valves at all, the reason valves get messed up is if the cold air comes back up and hits the valves and warps them, but he also has the cat in, so there is some back pressure to it as well.....
It'll cause awesomeness. If you're referring to the valve issue everyone fucks on about its only if you run it without headers as cold air will hit the hot valves and warp them. simply doesn't happen with straight pipes. You'll need to adjust the mixture though otherwise the motor WILL burn out a valve but other than that bikes run alot better without pipes.
he is right, think about it the cold air is heated up by the hot tubing and by the time it hits the motor it is not cold enough to damage your valves. maybe if the pipes were really short then it could happen.
i dont know exactly how bad it is for the motor but i have an 02 and i rode it for a day without the pipes it was loud and was a tiny bit slower but no harm done to the motor but then again i only rode it about an hour like that. nice bike!
OMG, you guys dont understand. obviously you would have too do a little jetting and engine work if you were too dun it with no pipe or a gp pipe, but with higher exaust flow you get much more power and preformance. and the sound is much much better. obv everyone has a different opinion on the loudness of there bike but most people, like me, like it loud and powerfull
we DO understand...Free flow isnt good...Bends your valves...an exaust with a little back pressure actually makes MORE power than free flow unless your on a race bike..Back pressure makes spread out power(Which is good for a i-4 cause they need torque too)
As for the loudness...Loud not only saves lives...But is just plain Bad ass :D
running no pipe will fry the engine with only a few added HP to the top end... i'll keep running my leo and get the better bottom end, mid, and good top end and my engine will keep running too :p
the back preshure is built into the headers most of the time and the muffler is just there to muffle the sound and mufflers can also make hp if they tapper outwards drawing the gasses out but it is not bad to run an engine without the muffler.
But here's another thing if you are ASE cert. then you would know that they don't call or say auto mechanic ever....TECHS or TECHNICIANS....so you're really stupid
AIR + GAS =INTERNAL COMBUSTION since it's powered by GAS not STEAM obciously
NOW SSLUSSHY all that crap moves the pistons and powers your motorcycle, guess where the excess air and gas comes out...if you're a mechanic you would know the answer to that right?
Who said anything about riding it like that? Nobody,and if you see my video i rev it for an even less amount of time so like i said it didnt do any harm,to assume we rode the bikes like this is stupid!
"*"...if cold air goes in through the pipes after riding it does alot of dmg! And no back pressure, its just stupid."*" NO! It does not! Stop spreading old wives' tails about engines, when you A) know nothing about engines (obviously) and B) Haven't done any serious or extensive rebuilding to even have a clue as to what you're talking about. The ONLY two things that bend valves is/are 1) incorrect piston-to-vavle clearence, engine will only one for about 30 seconds, or 2) not enough cam lift.
"Dude" a mechanic puts parts together and at best diagnoses what went wrong. That is a far cry from a master engine builder who makes or modify's the parts you just slap on and bolt up. I like how I explained clearly how it can't happen, and the best you can come back with is basically, 'yes huh, I fix cars, so its true" I don't recall seeing or hearing about you at the master engine builders challenge. Anyway I'm sure Edelbrock, Moroso, etc know more than you, they say it can't happen also!
You don't have to, Its obvious you don't have the knowledge to even begin to understand what I'm talking about. I'd be happy to explain it to you. Oh and for your ignorant information, the Master Engine Builders Challenge is open to only the best engine builders in the world. Hosted by Hot Rod Magazine and sponsored by the top ten engine component companies. The fact that you haven't heard of it, tells me all I need to know...which is you know nothing. Are you even ASE certified?
Why does everyone say "without exhaust pipe" when the exhaust pipe is still on the bike..? Only the silencer/muffler is removed.. just doesn't sound right..
oh yeah my step dad has a 1350 or 1300 softail w/e it was in '99 and thinks just b/c its like 1300cc's it can beat an R1 or an R6 for that matter his Harley is making less hp than a 600...My YZ250 beat that softail off the line and continued to beat it until i got to 5th and ran out of gears
harleys do not beat R1's and even if they did, harleys are for fat hicks that want to be noticed. Plus, if a yz250 beat this harley, then an r1 could beat it easily haha
while i'll agree that a harley will never beat a sportbike(for performance), i also have to say that i have no problem with a harley. they are some nice bikes. however, you need to consider what you're comparing- a cruiser to a high performance sportbike. theyre not even in the same category. it would be like saying that my v8 dakota could take a BMW M3 in a road course
dude, you only have to worry about low back pressure with 2 stroke engines. a 4 stroke, especially a high revving one thrives on low back pressure. this motor would love it. turbo motors also need back pressure, but just a little to spool the turbos up
Wrong, turbo's hate backpressure, backpressure is their enemy. Thats why the biggest below curve gains on a stock turbo motor are from exhausts. Want even more proof? What's the best way to increase the longevity of a Diesel engine? Lower EGTs, how do you do that? Bigger exhaust.
A turbo creates backpressure on it's own because the turbine has a slight amount of friction. A straight pipe on a turbo is the best you can do performance wise. If that' wasn't true then all the fastest import drag cars in the world would have mufflers.
Meanwhile a N/A engine needs a slight ammount of backpressure. Otherwise it looses low and midrange torque, and gains it back in the upper range.
i am not saying mufflers, just a little backpressure. not a lot at all. just a little bit. just a little. that is why you don't run a turbo with no pipe coming off it.
Well if you did that you'd start melting stuff because there's unburnt fuel kicking out the turbo lol. Aks any big single supra owner with a rich tune how long they drive around with that before they go back to the dyno to get it tuned out, and then buy a new rear bumper. But yea, the backpressure is caused by the turbo mainly. The B pipe is there mainly to help route gasses away.
Sometimes u can flow more gas with a little pipe rather than a sudden exit from turbine, but generally u r correct the less resistance from a turbo exhaust the better, although downwind turbo resonance will have a flatter wave form it mat still be possible to have tuned length?
I've sen some Pro am cars, most of them have this megaphone thing going on where the exhaust port is 3-4" and it goes to abouts a half foot just in front of the tires.
Its about length and diametre on 4 strokes, as pulsing gas exits pipe it creates a negative presure wave, this helps suck charge into cylinder/s, then a positive wave reflects any charge entering exhaust as a result an so the cylinder/s gain in terms of volumetric efficiency, 2 strokes r even more complex.
Some bikes had chambers that opened at low revs closed at high revs, this was connected to exhaust so when open had the effect of longer pipe, the same works on inlet length to.
lol... my harley has open pipes and it hasn't blown up? I think you guys need to learn about engine dynamics! Race pipes etc have minimal if any mufflers!! Drag cars run no mufflers, V8 supercars, tiny mufflers on huge pipes... come to think of it... dont F1 cars, and motogp bike all have tiny if any pipes? Wow... maybe they are meant for high perf?
if you adjust cam timing and have say a power commander and run relatively open pipes, the thing will scream and be tuned for higher RPM.
And be an absolute turd down low. Oh and your harley? It's a turd period, regardless of what you do for it. HD has been a joke for the past 10+ years as far as going fast is concerned. Only way they can compete is having a 1300 to run in the 600 class.
all these harley riders think just because they have a 1800cc big bore and shit they can take something lower in size but big things come in small packages they need to check their hp per cc b/c it cant compare to an R1 or any Inline 4
