my car is slow as sh*t somethin aint right

[bretthejet26]

just got back from the track... it was about 50 degrees, i have no intake, i have a boost controller set at 14psi, and i have a catback exhaust...

here is my "fastest" time

60'= 2.01
1/4= 15.4@89

ok and another weird thing was this... i trapped 90 mph w/a 15.6 but then i trapped a 87 w/a 15.5 why does the trap vary so much

and when i punch it.. my boost gauge goes right up to 14psi, doesnt feel like its pullin too hard... maybe my turbo sucks?

Why in the hell dont you have an intake? Man you are asking for it.

Well, since you have your intake off, check the compressor wheel to make sure everything looks right. Check for shaft play. You are probably venting to the atmoshere as well(BOV), which, unless you have a GM MAF, you should have had your intake on. Remember one thing, your car is about 14 years old, its not like its going to run the time you want it too, even though you have a cat-back, things get old and don't work as well over time. The main thing that determins your time, is how well you drive your car to that time.

oh shoot im so dumb... when i said no intake i meant stock i wrote that post last nite i was kinda tired... sorry about the mistake

 

[thehyena]

14b?

 

[bretthejet26]

yes 14b... sometimes it will pull hard and its nice.. but when im at the track it doesnt seem so fast feels like its just spinnin and not boostin

 

[91TSi FWD]

Does your car smoke at all? Are you looking at your stock boost guage, or do you have an aftermarket one? If you don't have an aftermarket boost guage...GET ONE. Then you can find out what you are truely boosting.

 

[bretthejet26]

nope no smoke... i had a new head installed about 16K miles ago because the timing belt snapped on the other one... i have an aftermarket boost gauge , and mbc @14 psi... it just seems like on the street my turbo will pull fine, but when it comes down to racin on the track.. it doesnt feel as powerful and my boost goes up fast , but i dont feel the pull

Have you done a boost leak check on the car?

Are these back to back runs or what, plus the 60' could deffinately use some work.

 

[bretthejet26]

they are about 1/2 hour in between runs... as far as i know i have no leaks.. i boost pretty well on daily street driving.. just at the track the turbo seems shitty like im not boosting that hard.. whats a good 60' time anyway

 

[thehyena]

try not launching at the track next time and just going from like 1200rpm's andsee what happens

 

[ECLIPSE4x4]

Well you still didn't answer the question about doing a boost leak check. But don't say you weren't told... Sometime track temps have a lot to do with things, making the car run more rich= less power.

A good 60" is to me... 1.7 or below for an AWD

 

[bretthejet26]

so i guess w/a better launch i could see high 14's? BTW these are all my times

run#1 (6:05pm)
60'=2.1
1/4= 15.5 @88

run#2 (6:33pm)
60'=2.1
1/4=15.6 @90

run#3 (6:53 pm)
60'=2.0
1/4=17.4@78 (missed 3rd gear)

run#4 (7:24 pm)
60'=2.2
1/4=15.9@89

run#5 (8:01pm)
