I got tired of people asking me what my car makes for power or what it runs in the 1/4 and not having an answer so I took it to my local track tonight. I had no idea how it would run considering the 155K miles on the shortblock, it isn't tuned, autocross suspension, 3.08 gears, stock clutch, etc. Well I didn't think it'd hook at all so I mounted up my 8+yr old ET streets and aired them up to 25lbs. I launched it around 3000rpms and quickly found out that the torque arm does a great job of planting the tires, however the stock replacement clutch gave up way too soon. It slipped BADLY on each and every run. I'd let the clutch out and it'd just howl and begged for mercy as it slipped and smoked as it tried to put the power down. The car was at FULL weight minus the lower part of the rear seat, the spare and jack. I ran it exactly as I drive it on the street minus the rear tires.
The engine combo is as follows:
-stock 155K mile shortblock
-morpheus power pipe
-65mm TB
-cobra intake port matched to heads
-AFR 165cc 60cc heads
-stock cobra 1.7 RR's
-stock cobra cam with new timing chain
-FMS shorty headers
-offroad X pipe
-summit cat back with magnaflow mufflers
-AFPR set at 45lbs of base pressure
-stock EEC
-255lph intank pump
-stock clutch and T5 with a pro 5.0 shifter
-stock rear with 3.08 gears
In my heart I hoped it'd be a low 13 second car and trap at least 104mph. Here's my two best passes.
60'.....2.044
330....5.600
1/8th..8.568
MPH...82.33
1000'..11.131
1/4.....13.28
MPH...105.26
60'.....1.985
330....5.558
1/8th..8.539
MPH...82.09
1000'..11.108
1/4.....13.26
MPH...105.04
I have no doubt if I add some gears and get a clutch that will hold the power that I can get this into the 12's as is. If I add a light weight battery, drag seats, shortbelt, etc I can only imagine how far it'd go. I doubt I'll head back to the track until I swap out the clutch, but you never know. All in all I'm happy how it ran especially for all of the limitations I have right now with this combo. You all know me well enough to know that I won't be happy until my autocross car can click off a 12 second time slip at the track. I'll put up videos later. It was weird crossing the traps in 3rd gear!
