I dyno'ed at 243 whp before my full 3" exhaust. So figure right now im at about 265 whp. Do you think with these mods ill be at 300 whp?

2.7 pulley
Tag Racecraft Meth Injection
Custom Tune
Heat Exchanger

Im thinking 5 whp going from 2.9 to 2.7. So that gives me 270. Meth injection will put me at clost to 290 whp. and between the custom tune and HE maybe another 10.

What does everyone think or have experience with?

 

I would say that with the items you mentioned, you will be real close. Do it and let everyone know.

 

you won't hit over 300 without race gas man (or a ported head and/or cams)... sorry to say.. I did get close on pump with meth I hit 296, but I haven't seen a higher dyno on pump yet. I think blown-4-banger hit 309whp on race gas though...

 

There's only one way to find out man. That kind of gorilla math isn't going to do anything for you. I'll tell you right now that depending on how agressive your tune is, you will be up there. I just highly doubt you would hit 300whp. It all depends on the dyno too. I assume you're going back to the same one you dyno'd 243 on, right? I just don't see it happening. Regardless, it doesn't matter what number you put down. The only thing that matters is how safe your car runs and what times you put down. Best of luck with everything, but I don't see 300...

 

Holy geez Vic, I hadn't seen your signature in awhile....sounds like you went all out! RWD conversion??

 

More than likely ill be getting it dyno;ed at Intense Racing because im gonna see about driving up and getting a custom tune.

 

22hp from exhaust?
damn. where can i buy that setup

 

a full exhaust. Header, Downpipe, 3" CTI exhaust

 

I don't think you will be there. Those mods should add up to about 275-280whp with a proper tune.

 

you won't make 300...close, but not 300

 

Anyone else with these mods please chime in and let me know what you got. Because if i dont get 300 whp. The moneys going for a 2009 Camaro

 

275whp dynojet

 

so only about a 15 whp gain going from a 2.9 to 2.7 and meth injection and a finer tune?

 

i see 285-290. you would need a smaller pulley and a ported blower and stuff in order to hit 300

 

2.55 pulley
60lb siemens flow matched injectors
C/A Header
C/A Front mount H/E
C/A Dual Pass
C/A 3" D.P. w/cat
C/A 3' custom side exit exhaust
Snow performance meth inj w/275 ml nozzle
XTC 3" Intake
NGK BRKE8ix plugs
(aka stage Paul)
296 whp 271 wtq (running pump gas (93 octane) , 70% meth, and 25 deg timing) 0 knock

 

think a ported blower would get you that 300hp?

 

I don't have meth injection but i have everything else you mentioned and i only have 260hp and 230tq sorry don't think so but Let me know so I can see the difference between meth and no meth.

 

might have

S/C is going the way of the dodo soon though.... aiming for 350wp on the stock motor... and 450whp with the built one thats going in after tuning and testing is done

 

do it!!!! haha! your warranty is long gone anyway according to the dictatorships(dealers) over in AZ.

 

**** my warranty was voided and my car was redflagged a long time ago... maybe after 3 months of ownership... I work part time as a mechanic and have a 2nd car, so it's no big deal to me. I actually might port my blower out next week since after sunday I probably won't drive my car much since it should be going under the knife in a week or two.

 

Honestly, wait till tag puts out their blower swap and see what numbers that puts out. You will not see 300 whp with what you are planning currently. And **** man, if you are planning on getting a 09 camaro anyway start saving and don't waste your money on the cobalt.... be happy with what you have now and realize that you would have to sink like 10 grand into the cobalt to make it nearly as fast as the Camaro.

On a side note though, how much torque did you gain/ lose when you saw the 20+ hp increase when you went to 3in exhaust. I would think you would loose tq at least in the bottom end.

 

Okay now you never mentioned that small mod before. I love my Cobalt but if you have the option of the 09 Camaro, stop modding your Cobalt and start saving that money. Those Camaro's are sweet.

Yes Tofu, I got tired of the hassle's with the transmission\driveshafts and the cost of trying to get them to hold the power. We have been having a blast planning this "small" mod. One cool thing will be the 13" rear street tires we will be running.

 

13" psssh... those are for pussies.... lol


j/k man... I can't wait to see this thing finished... not as much as you... but pretty close.

 

Temporary thread jacking

Your right, thats why the d\r's will be 390's instead of the 335's for the street. And I think a lot of us really want to see this done. I am going to Toronto to visit mt car the end of next week and to also discuss some of the finer details up close and personal. I will bring back pics.
