After a year since it's last pass at the drag strip and many upgrades, we finally got back for some shakedown passes at a test and tune. I recently installed a dual Walbro 450 lph in-tank fuel pump setup to cure the issues I saw at the dyno in the last video on the RX7.
Aside from some initial issues with my boost controller we quickly identified the weakest link in the system. One more upgrade will be coming very soon and we are going back to find a 9 second 1/4 mile!

The following includes everything I have installed on this car
Motor:
2011 4.8 Liter V8 out of my Chevrolet Silverado (I swapped the newer L83 direct injected 5.3 liter V8 with a 6L80E transmission into my truck for more towing power and much better drivability)

Stage 2 Summit Racing turbo cam, forged Summit Racing pistons, new LS6 lifters and lifter trays, hardened chromoly BTR pushrods, dual valve springs, LS6 intake manifold, truck style throttle body with adapter to fit LS6 intake manifold (drive by wire), Holley EV6 100 lb fuel injectors with aftermarket fuel rails (custom brackets to fit the LS6 manifold), custom exhaust from the heads to the tail pipe.
Transmission:
T56 Magnum-F (f-body t56 magnum)
Rear Differential:
Ford 8.8 IRS differential from a Ford Explorer. This diff has limited slip and 3.73 gearing. Hardened and plated chromoly axles with Ford Explorer outer and inner CV’s.
