My current mods are:
K&N Intake, B&M Shifter, Ingalls ETD, 60 lbs/hr injectors, ZZP 2.6" pulley, pacesetter header, full custom catless 3" magnaflow exhaust, and custom tune. I know my car SHOULD be in the 260-280 whp range, but it just doesn't feel like it. It feels sluggish and lazy. I can't tell if its because my exhaust sounds like a WRX and it doesn't SOUND fast or if there really is something wrong with it. Last night me and steve (Psykostevo) drove and scanned my car, and sure enough on a 7100 rpm run, it made 18 psi with no KR at all! So technically it should be fast as hell, but it just doesn't seem like it. I got to do a road course driving class today, and on the straight aways I was pulling away from a stock mustang GT, but it still just doesn't feel very fast. Any ideas what the problem could be?

 

i think it may be in your head mustang GT's are no slouch they run mid 13's stock w/ a good driver so if your pulling on them be proud

if you are tuned you should be fine get a wdieband and check your air fuel that could be a problem if your running to rich or lean!

gl bro


get it dynoed

 

What does it run in the 1/4 mile ?

 

Ah maybe it is my head, I don't know it just doesn't fell fast. I know all the signs point to it being fast as ****, but the "BUTT DYNO" doesn't confirm

 

has your car ever seen a dyno or a 1/4 mile track?

what are you expecting?

while i love the cobalt SS like a son it is not a skyline or corvette!

take her to the track and a dyno and tell us what results you get. the "butt dyno" can be unreliable at best.

 

It ran 14.59 @ 98 with intake & exhaust in 103 degrees and a DA of 3800 ft. I haven't been to the track since then.

 

HA HA HA!!! OK FALSE ALARM!!! I found the reason for my lazy sluggish performance! A little thing called BOOST BYPASS!!! I just did the boost by pass mod, took it for a ride, and came back to my house mouth wide open in amazment! I watched the boost gauge and it read ~18 psi from 5500 rpm all the way up to its 7250 rpm rev limiter! I also reached the top of 2nd gear faster than I reached the top of first when I was stock!!! THIS THING IS CERTIFIED AS "FAST AS ****!!!" I'm so glad it was something as simple as the boost by-pass mod!

 

if there was no knock then add timing. Or pay for a dyno run. But if u didnt have a base line done befor your mods then it will be hard to know exactly what was the gain.

 

y didnt ur tuner disable the boost bypas with hpt and what timing are u running

 

the thing is that once we get used to our cars they feel slow. That happens to me also, when I install a performance part is feels fast for aobut a week then the car feel normal or slow. Dont worry its in ur head. You kno when u notice when ur car is fast, when u race other ppl and you win. Even my buddy with the Typse S turbo says his car already feels slow but thats becuase he is used to it. he put down 360whp

 

Personally I don't know how to disable it with hpt and I didn't even ask him to do it. I know how to do it manually so I didn't car if he did it or not. I think we added 1 or 2 degrees of timing to the low octane map, and 3 or 4 to high octane map. Once I get a heat exchanger we'll add more. The problem is, at night it run fine with no knock but during the day it gets knock with the old tune. So we made it drivable during the day.

 

Yes your car wants you to mod it some more. A $1,000 per month will solve your problem, guaranteed.

 

Yes, but I'm running out mods that will make it faster! Heat exchanger, cryo2 sprayer, water/meth injection. Then what? I don't want to rely on the homosexual power of a turbo (no offence) to go faster. So what? Nitrous? Pistons?

 

Any chance your clutch could be slipping?

 

Start some drivetrain mods like a new clutch and flywheel and maybe some torque dampeners and motor mounts

 

You should've gotten rid of the bypass with hptuners. I can't wait to hook up the line back into the solenoid when I get my tune. For some reason I don't like the tube being plugged.

 

Last night I took it out and powershifted a couple gears just to see. NO SLIP! ZIP, ZERO, NADA!!!

 

Quick question... How do you do the Boost bypass modd... and would it be benificial for me with my mods? Oh... and I just sold my 4-wheeler guys! $3000 worth of mods coming SOON!!!

 

Then get a boost controller.

For the thread starter if you are looking for more to do, look at cams, headwork, porting blower, Water injection

 

Like my previous post, my stock clutch is holding suprizingly well so I'm not going to get a new clutch til the stocker starts going out. Also I already have the Ingalls ETD and wheel hop isn't really an issue for me.

 

HEY!!! Thats right! Cams are like 26 hp!!!

 

how do you do the boost bypass mod manually?
