Update on Prime Motoring's FA24 testing.

502whp/484 lb-ft @ 22.1psi and they ran out of fuel (stock injectors & HPFP). Still in the process of mocking up the IBR BRZ manifold kit. They're waiting on speed density & port injection tuning software now.

The most remarkable thing about it is i counted the amount of pulls we have made these last few days and this thing has seen 56 dyno pulls, in some terrible humidity ALL at 460+ whp & 460+ wtq and many with some very nasty break ups and misfires as he dialed in this thing. No break in whatsoever, right on the dyno, straight to ethanol, still on the original non synthetic oil, it has not left those rollers and has not skipped a beat. Tested before and once again tested after, 235psi compression & under 5% leakdown across each cylinder. Color me impressed with this engine. It has me looking very forward to the next gen STI. Now simply waiting on COBB Speed Density software and/or some port injection. @ibuildracecars sent me mockup adapters for the BRZ manifold and they arrived today so all thats in the works. I want to see where we can take this stock motor to so we have a leg up come time the next gen STI is released. Exciting times ahead.
