 All right, so here is the new pulley we're putting on That's the old pulley the 3.5. This is the new one. We're putting on the 3.25 pulley You can kind of see Definitely a size comparison Not a huge huge difference, but it's gonna make a I think at least another pound of boost Maybe a little bit more we will see Coming to blessed out there today We are in project storm HP tuners And we're doing some logging today We are planning on going down in pulley sizes. We're gonna put a smaller pulley on project storm and Try to turn things up a little bit more on this truck We're currently running the 3.5 pulley. We're gonna be trying out the 3.25 pulley today and see how much Pickup we get as far as boost. We should gain at least a pound Maybe two pounds Give or take on the pulley swap. So We're gonna check out the data log. We're gonna find out what we get So this first log is gonna be on the current setup on the 3.5 pulley And we're gonna do everything same day so we can get the exact comparison and try to Figure out exactly how much boost difference we're gonna see I'm special on this hot day. It is pretty toasty out here today again We'll make a pass real quick here on the old test strip See where we're at So here we go. We got the laptop going And we're just gonna make a couple of little pulls and See what kind of boost we're making today on this nice little hot summer day and Then swap pulleys and see what we can pick up With a pulley swap All right, so I'm gonna try to look at the boost gauge here and then when we get back to the fort we will look at the data and see Actual exact boost numbers per the data log But I'm just gonna kind of read off what I see on the boost gauge when we make this little pass right here Hopefully doesn't spin We're into we'll drive and We really don't care about the takeoff too much. We just want to see what we can make max boost wise here We go. All right, so we made the one little pole and From what I could see on the boost gauge. It looked like we were making about six pounds of boost We'll see what the actual data log tells us but it looked like around six pounds of boost Again, it's hot summer day So boost is not gonna be the best out here right now. Anyway winter time can make a big difference in your boost numbers for sure But it looked like around six pounds we will check out the data log See where we're at Stay tight. All right, so we're back here at the fort This is old project storm Torch storm supercharger that pass or that log that we're gonna look at here in a minute That was on the 3.5 pulley Holly high ram manifold and we have an air-to-air intercooler on the truck along with water meth injection and That is a that's it for anybody that's just chiming in that hasn't seen any of the old videos Tons of videos on this truck of Everything we've done to it. So if you haven't been caught up check out the old videos And we're gonna go in We'll go into the old fort and go check out this data log so again, it's summer About 85 degrees outside roughly and per The data log. Let's go down here. All right, so the BP barometric pressure Per that log we were at 14.8 psi barometric pressure. Now, which is pretty spot-on. I mean average is supposed to be 14.9 so we're gonna do the math and Subtract that from our max intake manifold pressure Which is gonna be right here intake manifold absolute psi So let's go through our log find the highest point that we had and See where we're at Kind of looks like we're holding up there. We go. So we went to 21.3 And that was right around 6,000 rpm almost as you can see up here 5947 so 21.3 I think 21.3 is gonna be our highest. Let me run through here real quick and make sure Yep, it's looking 21.2 21.8 so we hit 21.8 21.8 and that's gonna be our peak Yep, so 21.8 at about 6,000 rpm So Ryan's gonna do the math Okay, so boost gauge from what I could tell granted I'm trying to read it in the passenger seat So it's kind of hard to see it, but we made seven pounds of boost on the 3.5 pulley In today's heat not bad With an air-to-air intercooler so seven pounds so Now what we're gonna do we're gonna remove this pulley and we're gonna put on the 3.25 pulley It's a little bit smaller and go do the same exact log on the same road same temperature outside and See what we get. I'm thinking we should gain at least another pound maybe two pounds Give or take we'll see Obviously some tuning may need to be done after doing this pulley swap So we're gonna definitely watch the AFR gauge and see if we're still You know safe enough to be able to run it all the way out So hopefully we are the truck is definitely a little bit on the rich side. So I think we're gonna be okay But yeah, if the 3.25 can get us kind of where we're wanting to be that'll be great We're kind of wanting to be about eight You know eight to nine pounds of boost Would be perfect because before we put the air-to-air intercooler on the truck and we were only running the water meth That truck would make nine pounds almost ten pounds of boost on that 3.5 pulley which was pretty crazy But since we did add the intercooler and all the extra piping Obviously that takes a lot more Volume out of the compressor to fill all the pipes and everything so boost has dropped a little bit But the truck is still running great. It's making good power But yeah, let's get to it. Let's swap pulleys and go make another test run All right, so here is the new pulley. We're putting on That's the old pulley the 3.5. This is the new one. We're putting on the 3.25 pulley You can kind of see Definitely a size comparison Not a huge huge difference, but it's gonna make a I think at least another pound of boost maybe a little bit more We will see We made seven pounds. Let's see if we can make maybe eight or eight and a half So we're gonna get this thing put on go back out do another log. All right Mopar fam So we are ready to go. We got the 3.25 pulley installed Everything's locked and loaded. We're gonna get back in the truck Get the laptop HP tunas. We're gonna data log and see if we can get eight or eight and a half pounds of boost Let's go All right 3.25 pulley we are in storm. We're about to do the second log on The new pulley and see see where we're at Then we'll go back and we'll look at the data And see what the math tells us really made more boost, baby I'm gonna say eight nine pounds It was in between the five and the ten mark on the boost gauge and before it barely went past the five and I was saying six so Boost gauge shows dead middle between five and ten. So I'm gonna say eight nine pounds Let's go check out the data See what it says. All right Mopar fam. We're back here at the computer HP tuners and As you can see our BP barometric pressure is still the same as it was on the last log. It's fourteen point eight And we made a max intake manifold pressure of twenty four point one. So if you subtract the fourteen point eight We made nine point three pounds of boost The last log on the three point five pulley. We made seven pounds flat So we gained two point three pounds on That little bit of pulley change That's tremendous. So two more pounds. That's probably I Don't know. I would say that's that's probably good for maybe 40 or 50 willpower I would think somewhere in there. So truck should be definitely a little quicker on the track AFR gauge actually was like dead on it ran good sounded good So we're gonna send a log to Fly and Ryan FRP See if he can squeeze anything else out of it with this log and the new pulley So there you go a little bit of pulley makes a pretty big difference as you can see and Hell yeah, we're excited So storm last time out on that three point five pulley. We were running mid-13's and In You know summertime air like right now it's hot humid nasty The truck ran pretty good. So on this pulley. I'm kind of thinking we should be a little, you know really deep low 13's probably somewhere in there and Wintertime air easily should be able to get into the 12s. So hell yeah, there you go There's the differences between those two pulleys on this truck So stay tuned for more content. Don't forget give the video a thumbs up Comment down below what you think and we'll see you guys on the next
