Why is my car so slow?

[DaOnE51T]

Whats up guys,
I own a 1992 Eagle Talon TSI 5 spd.

Engine:
Stock 4G63T with 117,000 miles

Intake:
GM MAF Translator
Dejon tool 3" intake pipe
K&N air filter
RRE Spearco FMIC

Turbo:
EVO B16G turbo ported

Exhaust:
2g ported manifold
2g ported O2 housing
2 1/2 downpipe
No cat
2 1/2 cat back

Fuel:
550cc RC injectors
255 Walbro fuel pump

Drivetrain:
ACT 2600
Rebuilt Tranny

Here is my situation:
I went to the track a few months ago with it. The car went a best of 14.00 @ 101mph with a slipping clutch. I only got one pass in that night. The next morning I checked the compression and had 160psi across the board. I figured maybe its just the clutch slip slowing me down.

A few days ago I went back to the track to better my time. With a bad launch and a new ACT 2600, the car went 13.89 @ 101mph. I was shifting at 6,500rpms with no clutch slip.

What do you think is the problem? Why isn't my car as fast as everyone else's with the same mods?

THANKS

Seems like your not tuned at all. You should definitely be in the 12s with your set-up. Do you have an AFC or anything to control fuel? If not, that should be your next step.

he has the gm maf translator. you should be able to tune with that. get your logger(you do have a logger?) and use your translator to tune it.

Most likely just need to tune your setup but you could also have a boost leak(s). What were your 60' times?

 

[94awdcoupe]

how much boost are you running? what are you 60' times? has the car been tuned at all?

I tune with my GM MAF translator and Datalogger. Im running 110 octane with no knock. Im running 21psi. My best 60ft was a 1.80. THANKS

What sticks out for me is the low MPH which means no power production up top. In looking at your mod list, please add that to your profile by the way, I don't see an AFPR to control the 255 pump. That being the case, you're probably very rich up top and it's destroying top end power. At 18-20 psi and a decent launch, you should be running high 12's

Hope that helps,

Andy

If you're not even close to triggering knock, then you're still way too rich. I'd bet the 110 didn't help at all if the lack of an AFPR is accurate.

Nice 60' by the way!
