10.31@137mph road race LS7 FD RX-7 thru cats! I don't have the video of this pass; however I have a couple others that turned out pretty good.
Car weighs approx 2900lbs with me in it.
Built the majority of it myself. Some outsourced fabwork.
LS7 bottom end with Lunati billet rods/Wiseco pistons 11.25:1 compression
WCCH CnC'd LS7 heads (exhaust port only done back in 2009), QM600 cam, Textralia twin disc, 8.8" IRS Cobra diff with 3.73 gears, DSS axles, DSS 3.5" alum dshaft
LS7 intake, LS9 injectors, custom intake/cooling setup, Taurus 4,000cfm fan
275/35/18 fronts and 275/40/17 Hoosier 4+ year old dried out drag radials out back
big front road race front splitter not helping aero as back half should gain 28mph or more.
Ohlins road race coilovers full soft front/full hard rear, front sway bar removed
JTR 1 7/8" long tube headers, Dual 3" Random Technology cats into single 3.5" with Magnaflow muffler
91/e85 blend, Holley HP EFI, no dyno time ever
Mid/low 60's air temp, DA approx 500ft at Sacramento Raceway
Best et and mph of the day is this slip:
60ft 1.6693
330 4.4296
660 6.7130@ 110.78 mph
1320 10.316@136.88 mph
10.7@134mph pass
This one I missed 3rd gear. Nice rear view shot though.
Ordering up some 17" skinny Weld or Bogart fronts and new 26x10.5x15 ET Streets for the rear. Next time out I want to go 9's all motor. With the big/little tire combo I think I can shed another 50lbs+, remove passenger seat -35lbs, lightweight battery save another 15lbs.
