Any dyno, any mods with a 2.9, there's only a couple on these forums. Everyone says its definitely a gain in the ass dyno but I want to see real numbers just to get an idea. If you have before and after thats perfect, if you just have after that will be fine. So many threads asking if its good and saying it is but no numbers

 

If i knew of a local dyno I would help you out by getting one but dont know any local ones in NOVA area.

 

Alright, well if you do, definitely post up your numbers. I'm going to be getting one in a month or so and am curious to see what kind of actual gains they put down.

 

No one on this forum has any numbers with a 2.9?

 

Someone probably does but they are just lazy. Best bet is if you do it you can be post it up and everyone after you will have a good reference.

 

Yeah I know, that's what I'm gonna have to do, I just find it hard to believe no one has info and was gonna try to get people to post. Oh well, if I dyno soon Ill post it up soon after.

 

Good job man. I'd rep you but you know how it goes. I just need to find a dyno now too.

 

when i had the intense stage 3 kit, i had a 2.9 pulley and i dynoed at 249whp after exhaust, intake, header, and DP, i made 268whp

 

ill be dynoing soon, im just waiting til after i buy my house!!!!

 

sweet, can't wait, congrats on the house.

 

just put my 2.9 on tonight...trying to get to a dyno asap...i will let you know as soon as i have some numbers...
i see you have almost 15 psi there in your pic...in very good conditions i had about 14 psi on my stock stage 2...i'm hoping 16+psi with the 2.9...let hoepe maybe 250 at the wheel?

 

guys i am about to order a 2.85" pulley for nate on ebay i just want to double check that this is safe for stage 2...also all i need to swap the stage 2 pulley for the 2.85 is an allen wrench right????

 

^^ I would go with a 2.9. Better safe than sorry.

I know no one has blown up from S2 with a 2.8 or 2.85 but I wouldnt take the chance.

Also, I am seeing 16+LBS WITHOUT my 2.9, is this normal or is my car a freak? lol

 

Was it cold out when you saw those numbers? With just an airbox mod and S2 i saw up to 16.5 psi, but mainly when it was chilly out (probably around 40 degrees when i saw it). If you have a stock exhaust it will be prone to showing higher boost readings. Changing out your exhaust can help relieve the pressure because now i see barely 15 psi w/ 2.9" Nate pulley.

 

Pinoypapii is someone who I know personally, has stage 2 and a 2.85...NO ONE has any stories of anything blowing up from a 2.85" pulley. He checked it out a lot before he put it on.

He recently saw 17psi in this cold weather.

 

I usually see between 15 and 16 psi. i have a full header back exhaust tho.. but bump for the dyno #'s..

 

i run a 2.79 CA pulley on my stage 2 tune and it runs fine..i just dont beat it or take it past 6,500k untill i retune with bigger injectors..this is what i see everyday

 

^^^ My car runs right between that bar and the bar above that which I would guess is 16.5?

 

on my car i have stage 2 and a 2.85 pulley with a 2.5in catback and in the cold i normally hit between 17 and 18 psi on stock boost gauge

 

a 2.9 dyno would be nice. I also wanna get me a 2.9" but I can't delaying stuff having recently moved into my new house im spending money all over the place. The amount on just stuff for the house has already moved over 10k. Nuts I tell you nuts.

 

Was any additional tuning done or just the intense tune?

 

i have a 2.9 and put one of them ksport dash displays from my freinds truck. now i dont really trust any thing that can be plugged into your ciggaret lighter and give information but that rat bastard was showing 235 h/p with my current mods, dont remember the torque, a bit lower i believe. . . not really reliable information from me but maybe itl give you an idea.



ohh by the way my bro has a non-g85 ss/sc with just an intake and i dominate him all day

 

since no one has posted a dyno with their 2.9

mods at the time: 2.9", 42s, AEM CAI, Magnaflow Catback
(Mustang Dyno, at Tune Time Performance in Toms River)



this was like 2 days later

 

i dynoed with a 2.9 on the gm stage tune with a magnaflow muffler gmpp header with intake
stock on the same dyno i dynoed exactly 205whp 191wtq i have an 04 redline

244.5whp 228wtq makes me run 13.5

 

yeah, thats about right.
