so im sure that its been asked or said somewhere but i was wondering what HP and Tq everyone is getting that has Stage 2 and the manafold and the exhaust and what ever else they got from GM. thanks

martinsmu

If iam not mistaken, I think you'll be right in the 250hp/230Tq range.

Allshot

I say around 240 Hp and 220 Tq

martinsmu

yeah my #'s are a little high, but I still think 250 should be do'able. If he would get a 2.9 pulley, that would hurt niether!

I saw a stg 2 put down 240whp with the florida sun. So with manifold youll see just over 250whp for sure.

Allshot

I had mods like those and I dyno'ed 238 Hp and 217 Tq. But now I should be higher.

Allshot

You wont get 10 Hp for the gmpp manifold. You will most likely get 5 Hp

Pooch

cool. 240 is about all i want. i think im gona dyno bone stock and then after i get all my stuff on in febuary. should be interesting

martinsmu

well keep in mind that it all depends on 1, the type of dyno 2 temperature/altitude/humidity. 3 what gear you pull in. And we all know that some cars pull harder than others to. But that doesnt mean anything on the street. Bottom line, Iif you go all GMPP, nobody can give u hassell for warranty. I would recommend a magnaflow catback over GMPP, it wont change anything for you warranty, but will let more airflow!.... Maybe a CAI?? that could give you another 5-10 (expect more like 6-7)

Pooch

also, would the dual pass intercooler plate be good to have with that setup? i guess any drop in IAT would be good. but would it be worth it? if i do stage 2 and have to take off the blower anyway i might as well do that to i guess

martinsmu

DEpends on your warranty. I might be wrong, but I am preatty sure a dual pass intercooler could give you hassel if something went wrong with your motor.

martinsmu

You arent pushing big #'s neither, so that might be a overkill. If you dont care for warranty, I would go with a water/meth kit!1 Now that seems to be pushing good #'s. But again then you need to get your car re-tune, smaller pulley install. I mean its prob not at all what you want to get into if you where planning at the begining to go all GMPP.

Allshot

Stage 3 items arent covered under warranty.

martinsmu

Hey allshot, do you know how much the GMPP S3 would give HP over just a normal S2?

Allshot

I dont think they have released any specific #'s yet. I would guess it would put you in the 250 Whp range on normal 91 octane gas. Thats just my estimate though.

Pooch

can't you get just the dual pass? and if i can it would be covered. i am the Tech that is working on it. the pirks of working at the dealer i guess. and im sure it won't hurt anything by just haveing the dual pass in, not the NOS and Meth plat with 50shot!! thats over kill for me. all i want is a car that sounds nice and is faster than all the stock mustang GT's in my town. cuz everyone and there dog here has one!!!! so if i do all the GMPP stuff i shouldn't have a problem

Allshot

Crate engine depot sells just the dual pass intercooler.

Allshot

If you have stage 2 and a couple more mods you should be able to take one from a roll. Mustangs are fat and they are rated at 300 Hp to the crank. I believe they dyno somewhere near 250-260 Hp. They would be fast if they didnt weigh so much. If you go from a dig though Im pretty sure you would need alot of mods.

martinsmu

Well u should of specified earlier your job!! hahaha. No a dual stage intercool shouldn't hurt anything. And if it does, well u know how it is. My buddy worked at the dodge dealership and he fixed his srt-4 sometimes, but sshhh.

Putting this out there because u mentioned GT's, I ran a 03-04 one with just a GMPP S2 and from 50-120 I put about easy 5-6 car lenghts. The brand-new ones are faster though, but I think with the GMPP S2, manifold, catback from a roll, you should be right there and then some!! If i was you I would add a CAI for summer time, a 2.9 pulley. The pulley can be changed in 4 minutes literraly. That would give you another easy 10HP at least!!

Allshot

With the mods listed above you should be able to put maybe 2 car lengths on a new gt. Thats a pretty good gap.

Pooch

thats another thing. i realy don't want to put a CAI on in the fender, not in the winter anyway. the snow that gets in there!!! wow. i think one of the venders should make a kit that bolts up to where the 2.2 filter sits on the other side of the car. i know it would be more pipe but at least the car wouldn't be taking a drink if you were stuck in a freak rain/snow storm that dumped.
Or some one should make a ram air hood/with the filter housing so it is functional. Now that would be sweet

Allshot

Our cars arent tuned for a cai anyway. Its best to get one if you get your car tuned with hp tuners

martinsmu

I am taking mine off in the winter, and summer putting it on again. A little work, but hey thats the price to pay. And if you dont go looking for puddles you should be fine. Even if u suck a little water, the supercharge is made to spit out water so it doesnt get in the motor. Its not bullet proof, but its there to protect

Pooch

it is a lot of work just to check the filter(sa compaired to other cars) But i was thinking that if i remove the filter box and just put on a K&N style filter for the summer that would be ok. i think i saw a thred on this, but dose anyone know if there is a filter that fits the neck of the intake tube just off the air box?

martinsmu

I think AEM or K&N does one of those. either or one does make one. I heard the fit isnt perfrect where you tight it up to the tube, but its preatty good!
