i dropped my car at the dealer today to fix the timing chain, interior door handle and the reverse (it wont go in).....and when i get it back im installing my ZZP downpipe i just got today with cat...so i got 2 questions...with a cobra H/E added to my mods how much HP/TQ do u think i will make? thats with tune and 60# injectors...and how much louder will the car be with the downpipe?

 

The h/e won't add hp. But it will keep you from heatsoaking and losing it.

 

yea i knw i was just throwing that in there

 

depends on who tunes it and how much they can squeeze out of it.

 

i was thinking maybe 260/240...sound right?

 

maybe wit a 2.7 pully u mite see that

 

i dont wanna go that low

 

Doubt it. Maybe 250 on a normal dyno.

 

did u get a header aswell or just the DP?

 

Think he just got the dp.

 

weak sauce

 

im saving for header...

 

lmao. awesome word.

i'd say roughly 255 ish.

 

So you still have the stock cat back?

Low 240 something.

 

no i got a custom magnaflow

my mods:

2.85" pulley GM Stage 2 tune, Fujita CAI, B&M STS, Spec Stage 3 clutch, custom magnaflow exhaust, Waiting to put in: Dual gauge pod, Hi-Flow cat, 60# injectors, Progress Springs, ZZP Downpipe

 

Missed that...still 240 something...low 240 something at that.

 

u have to forgive steddy. we were up late/early in a stupid thread. lol.

 

the guy wants to street tune it also instead of on a dyno...so he can feel the car better

 

*mumbles something inchoerent*





What size DP?

 

3 inch DP

 

i still think u'll hit 250.

 

2.7", custom tuned with 60s, 3"DP, magnaflow cat back, K&N CAI made 243 on a cool day

 

stage 2 cars can hit that sometimes

 

What was your baseline?

You can make a dyno say some ridiculous things man, and really shouldn't go by that.

His car actually made less then a few things and only had about 5 more HP than some S2 LSJ's tere.


Made less then a 3.8 eclipse and a Solstice GXP
