685RWHP BMW 525
The car is a 1992 BMW 525i and from the looks of it it looks like your normal everyday BMW 5 series from the 90’s. Turn the ignition and you notice right away, its not your dads bmw.
It’s running a BMW M50 engine with a 2.8L (M52) crankshaft, Wiseco 8.5:1 forged aluminum pistons 0.020” over, and eagle rods. The turbo is a PT76GTS with a .81 A/R T4 housing, 4” turbo back exhaust, Injector Dynamics 1000CC injectors, all powered by a DTA S80 Pro ECU self-tuned. The car was recently on the dyno 10/22 and made 685.9 RWHP @ 28 – 29 psi and very conservative ignition timing on pump gas w/ 50:50 water/methanol injection (Aquamist HFS-6). For wheels its running 17×8.5 and 17×10 Rondell 72’s running 215/45/17 and 255/40/17. I also run Weld Pro Star 15×8” wheels with Mickey Thompson ET Street Radials in 275/50/15 when I need the car to go straight. The interior is a custom dyed BMW “Modena” and black theme with a Cobra Suzuka Kevlar seat.
And on to the dyno video.
