yeah.. i'm not believing this
my 2.9 pulley, 110ish IAT1...top of third was 134 IAT2's, water/meth injection, front mount heat exchanger, thats it for cooling mods. your saying that dropping the pulley down to a 2.7 and I'll be seeing 250+IAT2s.... BS
Stock cams peak torque is around 4800rpms, most dyno graphs show this. the graph doesn't look like belt slip (usually be seen as spikes) not a slow decrease like yours
240 IAT 2's with a 2.7?? thats the first time i've heard that...
Also your dyno graph shows that it was revved to 7k.. which is where it shows 190qtrq... peak torque says 245, which leads me to believe you didn't gain anything, show us your original graph showing 247@ 7k

Just some info for you guys.
My intake manifold, mildly ported and custom single pass setup. I also have CXRacing Front Mount in line with the stock h/e and a ice box/opt. B and meth. My IAT's at the drag strip tonight were 104 sitting in the staging lanes and didn't go over 113 at the top of 3rd.
I later logged a pull on the interstate, started at 88 and didn't go over 109.
I am also running a 2.9 pulley. Check my VBgarage for other mods.

My mods are: 2.7/pacesetterheader/40series muffler/60lb inj/manifold/tune. everything else is bone stock.
I don't understand how your ported manifold had lower AIT's then my real manifold considering the supercharger stayed cold to the touch and the manifold was really cold with a stock radiator?
I don't understand whats so hard my car did what it did and I have witnesses I can't explain this or that about your car doing so much better or what ever. You guys asked for data here it is! With my car I would of made awsome gains if the belt didn't slip!!!! it would of been more of a 40-50HP gain I don't understand how thats not good enougf?
As far as torque falling off it probably does when you run a stock manifold this is called parasitic loss from heat soak which effects torque alot. This is what I was told by my tuner. In my case it's where the belt started slipping I mean you could hear the wine sputter then get real quite this happend at 5000 RPM's!

trust us it was belt slip.
ok so the graph tells you more than just one number it says 190tq at 6800 rpms or so. did you look at the bottom of the graph where it says peak torque was 247, it doesnt say at 7krpms. it just says peak. his old dyno was 231tq or somehwere around there. you gotta read the dyno chart a bit more.
hes talking about the zzp tensoiner

Interesting, looking forward to your hpt data and everything else you have. Did you log w/ hpt during the runs and save it? That would definetly show any belt slip. Now couple that thing with some more cooling, front mount h/e and option b tank.

WTF?
240 before?
Jeez... um... I ran a 2.8 with no cooling mods for a while... and I never saw more than 150 on a hard pull.
Something was wrong with your car then.

All the work I did and all the gains I saw 30+ HP is just avarage?
150 with a 2.8 is pretty high. Take it to a dyno rev out to 7K and look at the temp from 6000-7000 I can guarantee at least 190 degrees! In my case with a 2.7 I happend to see more I can't help what my car made, the luminova's didn't work in my car.... I can absolutely promise you that the manifold I designed made it 100 degrees cooler and I made 30+ HP!!!!

I still don't believe it.
For a couple reasons.
Where is your dyno graph showing before where it was 31hp less before 5k??
Belt slip doesn't look like it happened until MAYBE 6.3K and that could also be your tune making it peaky like that
The car seemed to make a peak of 267ish (according to the graph) that is about right with a 2.7 pulley.
I'd also like to see logs of these 240+IAT and 140IAT
you can try to argue all you want, BUT TO ME This is not proof, this is someone trying to make a bunch of money
Also my 2.9 pulley on the dyno never saw above 134IATs revved out, 3 times in a row

About the gains... you may have seen 100* cooler... but we can't verify how that happened. A 230* IAT on a 2.7 sounds like an extreme heat soak pull, which shouldn't be compared to a 'normal' run.
As far as the dyno number... this is why I don't like dyno's... the variables can be skewed too far from the truth. Again, a heat soaked run compared to a 'normal' run shows false gains.
Edit:
I have my theories as to why we are seeing what we are seeing here... but I'll wait until more info is provided.

You guys could be right the AIT gauge on the first run was pegged and thats about 190ish not 240 that was an estimate. when I get the data you guys can look at it.

240 iat2's will result in no timing. a **** ton of fuel being dumped.
your intercooler pump was not working, or you had a **** ton of air in it.
it was not belt slip.
how about you go blow smoke up someone else's ass.

first off. you had a mechanical problem. not a fucked up idea problem.
second. those are average numbers for a 2.7 car with a stock manifold.
without log proof, this is smoke. "i was there, i saw it all" yea, thats fine and dandy. welcome to the internet age where that rule doesn't apply anymore.
ok moron. tell that that to the guy who had a 2.7 on his car for 20k miles with zero slip on the stage 2 belt and stock tensioner. bright ******* idea.
140 is average iat2's for this basic setup. what part of this do you not ******* understand?

When will you be able to get it back to the dyno with the belt problem fixed? also, do you have the iats logged from both dyno runs. the dyno numbers don't mean as much because they can be played with. I'm curious how much this manifold will drop iats, not so much the power increase.
