This very first test is with very low boost, and a "soft" shifting setup.Running a DKGECU trans controller to control the gearbox in this old car. Just wanted to share in case you guys find it interesting :) Steering wheel with paddle shifters.

Long time reader, new to the whole write-up thing so take it easy on me. Many of you already know my car, it has had many setups and combos on it and is one of 4 in the 9 second club, previous build was a Ali Barakat built/David Shoup tuned n54, on3 hotside w/precision 6766, 4L80 and 8.8 rear...

...with NO MODS. The only alteration to the vehicle's configuration is a custom tune from Halim@HCP flashed with the bootmod3 tuner. SpoolStreet member Chris (@SlowGTR) took delivery of the first A90 Supra in the midwest about a month ago and records are already being set. That in itself is a...

As many of you here know, the N54 has been saddled with a weak, plastic valve cover that is notorious for failing and causing various issues. The original cover was designed for stock boost levels (8psi?) and has shown that it can break multiple times in your vehicle's lifetime. Considering this...

With a new fuel system, maintenance, other odds and ends taken care of I went back to the dyno and sent it again. Boost only on pump E85, no other power adders were used. I believe this is a new horsepower record for the fairly common N54 6266 top mount setup. .. .. 809 WHP / 755 WTQ...
