Just got back from the dyno.

Mods-Intense Stage 4 (2.7" Pulley)
GM Performance Exaust


Sorry i cant scan this but here are the numbers.

3rd Gear Pulls-Dyno Jet


HP-244.20 TQ-233.25-Humidity58%-86.29 Degrees
HP-240.45 TQ-228.45-Humidity61%-85.01 Degrees
HP-244.36 TQ-231.46-Humidity61%-84.91 Degrees

They said i was running a little lean, my A/F ratio slowly went down from 12.3-12.2 after 5000(Basically when i hit full boost of 17psi)

Hopefully this ship will be able to tune my car soon so i can through on a 2.5" pulley and my intake...

Thoughts? comments on A/F appreciated.

 

Doesn't Intense say you're supposed to get 265 whp from stage 4? On a dynojet, no less...seems lower than expected.

 

The hp numbers look a little low but the tq numbers look pretty good.

 

Those are pretty close on the numbers I got. Mine were a little higher and I did the pull in 4th gear and I don't have the exhaust. I do have an intake though. I don't know if that could have made a bit of a difference.

 

im afraid to put my intake on, i think it will run lean...., and its could my lower number be b/c of the exhaust? since the PCM isnt tuned for it?

 

Then again some stock SS/SC's dynoed stock at 198 hp and lower torque...

 

Every dyno i have seen with the intense kits is lower then what intense claims. I say false advertisement. And yes i know every car is different, but not 20hp different.

 

I ran 248hp and 240ft/lbs with the Intense Stage 4 (2.7).
I did have my 20's on though.

 

speaks for itself...

 

cough*bullshit*cough cough

I was freaking there...all cars are different and the weather temps between when they tuned Rob's car was different than what this guy had tuned and rob had different mods than this guy did too. Rob also had a cat delete. Right there is a few extra HP this guy is lacking. Well a lot with running that much boost you will gain more than 5 hp from a cat delete and fixing the big ass pinch.

Now if you want, feel free and argue Rob Archer on his #s...hell...I made the 249.5whp and 233.3lb/ft doing testing for one of their other stages. It is dyno proven, but who the hell can guarantee that everyone getting the same mods will have the same #s!

There is a guy that put down 220whp on his car stock. You think him adding all the same mods as someone who put down 200whp stock will end up at the same #s?

 

well this was on 93 octane, they probably will say since its not any higher its going to be around 240 but with higher octane hp numbers of 260+ can be reached etc....

hopefully when i get my 2.5, intake and custom tune done, i will be good.

 

This whole thread is a good example of why you can't rely on dynos to tell you how much power your car makes. That's what a drag strip is for.

Go get some *real* numbers!

 

What happens when you can't put the power to the ground, is that a good measure of power? I see what you're saying, but the strip is how fast you are, not how much power you're making.

 

Pretty sure Rob was on 93 too...only thing around here like that is Sunoco 94 and then basic 93 from Shell, BP, etc. Doubt Rob drove from Indianapolis to Columbus on 100 or 110 octane.

 

shitty oh well, my track numbers are in my sig...

 

Trap speed, regardless of how long it takes to get there, is a great indicator of power. Granted, a bad launch will cost you a little, but I'd say it's more accurate than a dyno.

When I did my runs on the 1/4, all 3 of my 60' times were very different, yet my trap speed did not vary more than .3 mph between all 3 runs.

 

So you pretty much wasted your money on the PCM if your getting a custome tune.lol. Don't worry im in the same boat. . I have a custome tune coming from Tune Time Performance.

 

Okay, that sounds reasonable.

 

Yesterday I dyno'd 226 hp 197 tq with stage 3, intake, exhaust.

I pulled the intake off last night and it seems to run MUCH better. I firmly believe I was pulling timing with the intake on.

 

interesting numbers ... stage 2+ a 2.8 pulley gets right about there as well

 

Thats funny...where all the cars are different, you think the best tune you can get is by someone benchracing all the items you have and come up with what it should be set at? You better be going there for a actual custom tune. INTENSE and GM Stage tunes are good base tunes until you can go get an actual dyno tune to maximize what is best specifically for your car.

 

Yup, tip for anyone wanting to start modding, just by the products and get your own tune lol. Is 12.2 Lean? if so why would intense be selling this PCM for stage 4 and stage 5, so right now if i threw on a 2.5" pulley, it would run lean definetly. Would my exhaust through it off that mucH??

 

I agree with this too...

 

The Hp is about the same but the tq is lower with the 2.8

 

No one has answered this one yet. If 14.1 is perfect, why is anything higher than a 13 considered dangerously lean on these cars? I know there must be a reason people keep throwing out 12 and 13, but I want to know too darn it!!!
