i'm max boosting 17 on my 3"........

 

You have some SERIOUS restriction!

 

please explain the restrictions? on my way home from work tonight i'll really get on it and see what the max boost is.... i thought it was 17psi

 

ya ouch man. when I had a 2.9 i was boosting maybe 16psi at the top of third. You might wanna see why your holding so much boost.

 

it might be the cool air down here

 

a 2.9 should net about 15.5-16 restrictions in intake, header, downpipe, exhaust system.. your cats could be clogged any number of things could make that higher than it should.

 

ok, i would think that those restrictions would cause the boost to be lower. i'm going to be replacing the aem "air box mod" with an injen here shortly. i'm still on a stock header/dp.... those are next on the list.

 

Air backing up = more pressure.

if you are blowing through a straw, and you pinch in the middle but keep blowing, is the pressure going to increase or decrease?

 

shut up! i'm not talking to you!

 

Hahaha..

 

Could i here a video of you exhaust??

 

do u think the 2.9 is worth it? i can get one for 40bucks from a local guy. and are they easy to take on and off? and did u use the stock screws?

 

Yeah, you can do it... won't benefit fully from it untill you get tuned. But they are pretty easy to take on and off I have had like 5-6 different pulleys on my car now!

15mm wrench or vice grips for the tensioner push down and towards the firewall, to loosen the belt.

As long as they didn't use locktite on your stage 2 bolts it will be a 15 minute job!

 

alright thanks im gonna buy one now prolly hopefully it will make a little difference but a cheap 40buck mod

 

You'll notice a little more torque nothing HUGE though! .5-1 more pound of boost!

 

every little bit helps ;]

 

I skipped right over the 2.9 to a 2.85, 2.8, to my 2.7 I'm rockin' now!

 

lol mr. bigtime lol
but i have to keep my stage 2 tune. and it seems 2.9 is the safest one plus i am picking it up prolly within the next 3 days

 

Yeah, the 2.9 is for the most part SAFE on the S2 tune.

 

specially with the h/e for cooling. and i hear stage 2 tunes run rich and this helps

 

Yeah S2 tunes are rich as hell... in the 10 AFR range it's pretty... no VERY conservative!

 

wont see 270.. not even close. you dont even have meth

 

Jesus you guys, I said get the 2.9 and tune! That is the most beneficial thing to do. The 2.9 alone is not that much of a gain. 267whp was on a dynojet yes, but I'm sure that the 240 that rallycobalt06 put down on the mustang dyno was equal to my ****. Oh, but wait 12-13% bullshit...whatever...I'd love to race anyone that talks ****. If you don't have numbers stfu.

 

Dude chill out. No need in trying to be a big man online. Seriously. Remember all dyno's are different. I put down 253hwp with the 2.9 on my dyno. And I'm pretty sure from a roll we would be dead even. From a dig well, driver mod

 

Sorry man, didnt mean to come off as a ****-munch...I just hate seeing what dyno has "real" numbers...
