I am going to a quarter mile track this Saturday and was woundering if anyone had an estimate on how much hp I have....

Current mods;
2.8 pully
42lbs injectors
Hahn racecraft shorty header
Slp loudmouth catback 2.5 exhaust with a hollowed out muffler
Gm stage 2 tune
Stock intake
Irdium plugs

I am getting it professionaly tunned next month and putting a meth kit in. Thanks guys!!!!!

 

230-240whp i would say cause the heat soak with 2.8 and i'm sure your maxing out the injectors especially with the pig rich tune

 

Yeah I'm thinking I will do the cobra heat exchanger and prob step up to 60lbs injectors. Do you think that will make a difference?

 

yea, 230ish whp and 215ish wtq.

 

with a tune yes for sure, that heat exchanger will keep your iat2 temps down so it'll give back some

 

yeah I can't wait for the tune! The Balts down right now... Broken axle.... Go Figure. So I ordered the stage 2 axles and should have it back up and running by Thursday

 

sweet deal you might look into rotated mounts from ott also they'll help eliminate wheel hop just something else to fall back on. that tune will unlock quite a abit of power, who's tuning it? with meth i think you'll hit 260+ fairly easy

 

his name is jeremy... He has been mentioned in some big name magizines. He says he won't stop untill he get 50hp out of it. He comes up from florida... He only tunes gms. other than that I don't know anything about him. LOL

 

sweet deal let us know how it turns out

 

will do I plan on posting a before and after dyno slip.

 

would be good for people to see

 

agreed!

 

btw, WRONG SECTION NOOB!

 

really that low i thot w. 60's and a good tune he'd be at 250 260 whp easy w/o meth ive seen a **** load of these motors make 220whp stock...

 

Well where the **** do u want me to post it

Well I guess we will see after I get it on the dyno and tune it.

 

what kind of power would he be looking at with a 2.5 pulley, 60s and a higher meth water mix?

 

My Stg2 w/ 2.8 & GMPP Exhaust made 240whp on an outside dyno in 100*F heat, with high humidity, and IAT2's starting around 150+*F. About the worst conditions possible

 

of course with teh extra heat exchanger

 

...and you are in PA... how the **** are you going to a 1/4 Mile Track this time of year???

 

Cecil is having an open track day.

 

^^^probably for snowmobiles

 

No cooling mods and with 42's, im scared for your car, I would go with a 2.9 and you will make 250 whp a least and get NGK 1 Step colder plugs, makes the car happy.

Do you have the stock dp or aftermarket?

 

the dp and the cat are stock. yeah i guess i really do need to do some cooling mods. and the one step colder plugs, do you know of any auto part sores that carrie them, or is it an order online thing?

 

I just got mine from cobalt addiction, got to my house in 2 days later

 

sweet looks like im going to cobalt addiction!! did you re gap the plugs or just leave them where they were? sorry for all the questions just trying to prep for the races lol



in that case i might have a chance!!!
