12.6 - terrible time slip ... for my set up

--------------------------------------------------------------------------------

I went to track on weekend, and it was terrible.

At first launch it bogged ... 2,2 sec for 60ft.

12.8 at 188km/h

second I set the 2 step up at 6400 and 20 psi ... had a very bad wheel spin in first and second gear ... I miss shifted on third

1.9 60ft

12.6 @ 190 km/h

Remember that here in Brazil the tracks are shi* and about 30 degrees at the track.

I'm really mad about my results ... as I have a 3037 HKS kit with 1.01 hot side Comp cams 272
HKS cam gears,
AEM set at 28 PSI - 98 RON Octane gas.
A/F @ .79 Lambda
Ferrea oversized valves
Wiseco
Pauter rods
HKS Head Gasket
ARP Head Studs
Really big custom intercooler 2,5 pipes

I looked at my logs and realised that I'm probably having a lot of back pressure from my turbo or from my 3inch turbo back.

I could not set the boost higher than that ...

Any inputs ???

 

wow....i'd be upset too. the time in my sig is basically an intake/exhaust and tune.

 

good luck with your car man. i know it can be frustrating.

 

you don't know how ...

thanks anyway !

 

Your second run shows some power,118mph. How is the lag on the setup and where are you shifting? 28psi might be hurting you on 93 octane, unless it has a rock solid tune.

 

we have a drag racing section...
