ok i have spec stage 3+ clutch 9lb flywheel zzp 2.6 pully pully tensinor stage 2 meth cx racing heat exchanger 60lb injectors header catless downpipe 2.5in exhaust 2 step colder plugs...i got tuned today and dynoed 230whp???? Wtf is wrong....my buddy with the same set up on the same dyno put down 271whp....did a compression check 1-200 2-185 3-180 4-200....anyone got any ideas

 

your tuner is the problem.

 

*shakes head*
You guys and your 2.6 pullies...

 

Did you check your IAT2's I know you have cooling but how hot are you getting.

Other than that your car or tuner has a problem.

 

x2

 

Drop to a 2.8 or 2.9 pulley and learn about heat. You can't imagine how much heat that bastard makes. You will get 20 HP by just the colder air.

Hey also check your IC pump

 

what kind of dyno?

 

my iat was 94 and my exhaust was 194 also my car and my buddys maps were within 100th of being the same my a.f was all in the mid 11s

 

mustang dyno?

 

No ****...
People around here drop pulley sizes likes it's gonna make their dick bigger or something.

There is a lot of know how involved in making power with a 2.7 or lower. And those happen to be the guys that like to tinker with the car all the time.

 

same guy who done my tune done my buddys tune and he runs the same dyno...it was a mustang dyno...about to go get on a dyno jet to see if there is a difference...and by the way i was asking for some advise not some smart @ss making stupid comments

 

Then you came to the wrong forum.

 

Well you are making it easy for us. If you can't show us logs and have other info for us then all we can do is make general statements.

Generally the only reason you make low power on a smaller pulley is heat. That's it.

 

wrong forum then bud...

oh and check your grammar

 

You need a 2.5" ring.

 

yeah but i have everything u need to run this pully and my buddy have the same things done down to same clutch intake....ect and i wasnt heat soaking...iat was at 94

 

exactly... and the 2.6 people around here wonder why i run faster times than them with a much larger pulley

 

Then your tuner **** the bed on your tune.

When you say IAT, was that IAT1 or IAT2?

 

If your IAT2 was under 100 I'd be very very surprised. Most see 130 or above with a small pulley like that.

 

All the people with big pullies, slicks, and full boltons wondered why I was able to smack their times around with nothing but a 2.5 ring, injectors, and tune on street tires.

 

all in the tune.


btw, with a H/E and methanol, theres nothing wrong with a 2.6
and to suggest he will GAIN power going to a 2.8 is idiocy.

you guys take this heat thing to far sometimes.

 

100 shot

 

It's not the heat that concerns me about sub-2.6" pullies.

 

Just a quick ? , how much more power does it take the motor to turn a blower with a 2.6 compared to say a 3'' pulley?

 

does the car feel slow? Dynos can be messed with. Maybe it was out of wack for your runs. DID YOU ASK YOUR TUNER WHY IT WAS LOW? If he tuned both cars, I'm assuming he would have mentioned if something was off.
