We can easily obtain 250-260 when you include I/H/E. That's only 20hp off from the origional rumor. That's enough power for me out of a 2.0L engine JMO.

so u guys are disapointed? keep in mind gm allready underated the vehicle what makes u think they didnt underate these packages? remember insurance rates are high if gm sayed stage 2 is 280hp then imagin insurance rates for the stage 2 upgrade. also do u think mopar's upgrades are much better for the srt-4? stage 1 mopar (comes w/ the car now) gives the car "230hp" from the 215. stage 2 i believe is 250hp, and stage 3 is somewhere in the range of 300+hp, so gm is on track and remember this will give ya insta tq no lag, and i would imagin that 245hp is gonna be really underated and really bbeing arorund 250whp-260whp. so thats definatly putting it in the 13's. add intake, exhaust and header and you'll be pushin closer to that 280whp mark if not more. hell P&P the s/c, larger t/b. and possibilities are even greater.

so imo these upgrades arent bad at all.

I'm super excited about these stages... the only rumor that has me on edge is if it will be under warrenty still .... cause i remember dodge saying stage 1 and 2 would be under warrenty for the srt-4, but then when they came out... that was shot down.

astrocrep

Yea, I am really excited about these as well... but I am praying for the Warrenty sancations... It makes me nervous to read that these upgrades can be user installed...

I guess will have to see...

When Jonel and I talked to the GM reps at the Small Car Bash they said maintaining the warrenty was a very important part of the staged upgrades for the SS/SC and that you would be able to drive the engine just as hard as stock and not have to worry about problems.

I am 99% sure they will keep the warrenty on the staged upgrades, hence the modest gains.

ShaunK

What kind of Price do you believe to be associated with these upgrades?

DanM

That's the million dollar question.

selfinfliction

i heard the first 500 people to call into gm this afternoon will get a $200 discount on either of the stage upgrades they choose.

Just a note about injectors.

Most injectors are color coded. Some are pink, orange & red. It is a quick and easy way to see what lbs they are.

cvenom2122

stop saying this isnt alot of power! you can now offically beat a STI from a roll

with a intake header and full exhaust you can beat them by even more (they dyno at 250 awhp) this is great but im gonna get the PSI FI kit and just get the reflashes when they come out

Maverick

Hey man just remember the psi fi piggy back kit is based on the current ecu calibration. When you reflash it with one of the stage upgrades you may have to ditch the piggy back completely?

cvenom2122

im cool with that atleast ill have the pullesy and what not

i own a set of 39 pound cobra injectors , and they look nothing like the ecotec injectors , they are skinny injectors like the 03-05 eco injectors and the 99-02 2.4 tc injectors

the 2.0 s.c injectors are 370cc injectors , from what i remember and are fat injectors , simialr to the 98-older injectors in looks


and keeping in mind the 205 hp is pretty much wheel hp , 242 whp would be closer to the 272 mark , sound kinda fimilar ?? the SS272 hmmmm


couple GM's upgrades , with intake , and header back exhaust , and your at or over the 300 mark


all with out going inside the motor , seams to make sense to me

im sorry, but i must disagree with these two. You already have ~75-78mm TB (calculated from the pic zinner posted). That thing is HUGE! GTP owners upgrade to 75mm TBs (LS1 size). Saying that a larger TB will net you more gains is crazy. There doesnt seem to be any restrictions in the TB, so there is nothing to port. The walls of the TB are very thin. Any porting done would ruin the TB as it would be too thin, or you could puncture through it.

Also, unless youre talking about just the inlet of the SC (which i dont have the specs of to compare with the TB) you will not gain from porting the SC. Infact, there is no where to port on the outlet. That rounded off triangle is there for a reason. Thats the most efficient configuration for a roots style blower outlet. If you open up the triangle too big, you will lose efficiency and thus HP. The m62 used on the SS looks very much like the Gen V m90 on the 04+ GTPs. Eaton has said that the GEN V m90 will only gain 5% more efficiency if ported in certain places extensivly.

hey guys, im new to the site and i just wanna say this site is awesome. Anyways, with all this talk about the added horsepower... do you think the stock transmission will hold up? i mean i konw they will for the GM upgrades, but if some people apply their H/I/E, would the transmission be able to handle it all?

MarcS

Welcome to the site

Yes I believe the tranny will hold up.

alleycat58

I think it gives the HP rating in the build book online. I'll have to look...I'm pretty sure tranny is good to 400hp but I could be wrong.

chevyracing19

wow! nice haha sonuds like a damn reliable tranny.

alleycat58

Don't take what I wrote as gospel truth...I'm still trying to find the official numbers, so I could very well be wrong.

Actually stage 1 doesn't come with the 04 and 05 srts. The fuel injectors from the stage 1 kit come with the car stock...Since the stage 1 injectors come with the car...the stage 1 kit doesn't add much at all for the 04~05 srt's.

for the record the staged upgrades for the srt are...


Stage 1 (PCM reflash) 240hp 260tq -- $399

Stage 2 (Stage 2 PCM, 682cc/min injectors,wastegate,tip sensor,'turbo toys') 265hp 280tq (280hp 300tq in HOM) -- $1599 or just $1000 w/o 'turbo toys'.

Stage 3 (turbo upgrade kit,75 Psi Fuel pump,Stage 3 Pcm) 310hp 325tq (355hp 365tq in HOM) -- $4199 for whole kit...$3000 for stage 2 upgrade.

of course those prices are from mopar...you can get them from other dealers for a few hundred cheaper.


I'm wondering if GM will have something like HOM (high octane mode..100+) for the SS/SC, it'd be a nice feature.

selfinfliction

how does that work on the srt, is it just a flip switch chip or does the ecu actually have two programs in it?

xonic

Just press the button to activate.

selfinfliction

that's a pretty slick setup
