First run at the track
First run at the track Car and Mods:
* 1994 RX-7 Base Model
* LS1 Block
* T-56 Transmission
* TSP PRC 5.3L Stage 2.5 Heads
* TSP Torquer v2 Cam 112 LSA
* Cometic .040" Head gasket
* MSD 8.5mm wires and protective boots
* Ported Throttle Body
* 25% Udnerdrive Pulley
* JTR/Sanderson 1 7/8th Long Tube Headers
* LS6 Intake Manifold
* TSP 7.35 Pushrods
* LS7 Lifters
* LS2 Lifter Trays
* LS6 Oil Pump
* NGK TR55 plugs
* 4.10 Torsen Rear End
* Aluminum Driveshaft
* Exhaust: catless custom true dual 3" piping through Magnaflow X-pipe and 5" straight through Magnaflow mufflers
* Weight with me in it, 3050 lbs.
Yes, I was sleeping at the light! Just wanted to practice launching
Turned rear suspension to the hardest and front to the softest for weight transfer.
Ran the 245/50/16 Nitto NT01 tires @ 15 psi and still could only get a 1.9 60ft without spinning.
Expected a little better times. The only difference from the dyno to the track is changing out my 7.40 pushrods to 7.35. I had to shift into 5th gear towards the end with the 25.6" tall tires and 4.10 rear end. A heat soaked IAT probably caused some timing to be pulled as well.
I think my tach was off a tad. I should be able to hit 127mph with my setup and a 6800 redline.
Probably won't go back to the track for a long time. I just wanted to run it once to see how it would do. More of a road racing and auto-x guy.
