Buckhead Imports hits 669 wheel horsepower with their low compression built motor E39 M5 S62 V8 running the RMS supercharger kit with Vortech YSI
Very impressive results here and nice to see some big numbers from supercharged S62 V8's. This car here is using the RMS supercharger kit which obviously features a supercharger (Vortech YSI) and RMS associated hardware including what is one of the most beautiful plenums in the BMW aftermarket. This E39 M5 features a built motor S62 V8 with low compression pistons and forged internals which can handle more boost from the YSI allowing for an impressive 669 wheel horsepower.
Buckhead Imports did not mention what fuel they used although at 22 psi of boost for this run one would assume 100+ octane race gas. It will be interesting to see if they spin the YSI anymore than they are but these are some great results and it is nice to see more built motor supercharged S62 V8's.
Great work by Buckhead Imports and a solid system from RMS:
