Turbo_Rampage

I took my Rampage to the track last friday for the first time and i had alot of launching problems, but overall it was a fun time. This was the first time i ever went to a 1/4 mile race track and raced and i'm surprised the car made it home after the BAD wheel hop i was having! I ran 3 times and out of those runs i tried 3 different lauches and none of them helped...
This was my 1st run and one of my worst times-
R/T ... .396
60 ... 2.417
330 ... ??? Missing...
1/8 ...10.766
MPH ...73.80
1000 ... 13.688
1/4 ... 16.106
MPH ... 94.30
I launched at 3500RPM and the wheel hop was so bad the upper radaitor bolts came loose and left my radiator hanging, and half my gauges fell out of the dash. I had to lift the throttle in 1st for it to stop.
Here is my fastest time-
R/T ... .412
60 ... 2.654
330 ... ??? Wasn't on my slip, :confused:
1/8 ...10.253
MPH ... 75.72
1000 ...13.138
1/4 ...15.530
MPH ...95.00
This was my 2nd run down the track and i tried launching at 2000RPM to avoid the wheel hop, but it was still violent and i had to lift off the throttle through 1st gear for it to stop, but other then that it was a perfect run down the track shifting at 6000PRM through all the gears and hitting the traps in 4th gear peaking 95MPH.
For the 3rd run i tried easing the clutch out at 4000RPM for the launch, but again the wheel hop was so bad i had to let off again... I lost the lime slip, but i remember i ran a 16.1 at 95MPH again. Oh for all of the runs, i did a quick burnout to clean the tires off.
I dont get what is causing the wheel hop to happen, but when i try launching on the street at those same RPM's i did at the track my car just smokes the tires and goes with no wheel hop. I guess its the stuff they put down at the track to help with traction...
Here is a list of the stuff done to my car-
-Koni adjustable coil over struts with #275 eibach springs (struts set to full soft)
-Poly sway bar and control arm bushings.
-Moog ball joints and tie rod ends.
-Crab rims on basically brand new cooper 205/50/15 summer tires.
The front suspension is all brand new and tight with the best stuff i could buy, so i dont understand why it's doing this... The rear tag axle is flipped from lowering it and has all new bushings and Monroe Sensa-trac shocks, so the rear suspension is really stiff.
For the motor and trans-
-1986 2.2L rebuilt with T2 rods and swirl head.
-1988 TBI roller cam.
-TU Garett T2 style turbo with quick spool.
-MP GLHS stage II computer with MBC set at 14PSI
-+20% injectors and AFPR (Air/Fuel ratio set at 11.5 to 1 @ WOT)
-Base timing 10*
-2 1/2" SV and exhaust right to the back with a flowmaster muffler (no CAT)
-1 peice intake manifold.
-K&N cone filter.
-GLHS radiatior and intercooler.
-T2/T3 clutch.
-Poly motor mounts and solid bobble strut.
-89 A555 with the 3.85FD and open diff.
-91 octane gas (thats all the pumps have around here)
I might be missing a few other things above, but overall i think it would of run low to mid 14's if i could get it to launch properly... with no spare and a full tank of gas it weighs around 2100lbs last time i checked. Does anyone have any ideas why i'm getting wheel hop?
Thanks
