HorsepowerFreaks E46 M3 Record - 667rwhp (800bhp)



667rwhp (800bhp) Uncorrected

We're pleased to report some more progress. We got our new fuel system installed and our new clutch so we could turn the boost up a bit more. Last time we made 603rwhp SAE at 11.5psi. This time we maxed out the T67 turbo at 667rwhp at 13.5psi (Uncorrected - which is what the car actually put down). The SAE correction put it at 634rwhp because it is so cold today. I published both graphs below. These numbers are all on the stock engine and stock exhaust. No modifications whatsoever have been done to either. We could have made more power, but that was all the boost the turbo had. This shows that the stock M3 engine is stronger than many people give it credit for. We did nearly 100 dyno pulls today many of them over 600rwhp. The lower dyno number in the graph, 263rwhp was of the "same" car right before we put the turbo kit on it.

Here's a video of the dyno pull.



Here's a video of our new HPF Feramic clutch on the street. It easily held 800bhp and has absolutely stock like driveability and stock like pedal effort.



Here's a short video of our M3 on the street.



Another video on the street.



Another short pull on the street.



More driveability...



Don't forget to leave feedback on YouTube if you like them. Thanks.

Take care,
Chris.

I am a total turbo noob but how does air pressure affect an engine, such as pistons, piston rings, or crankshaft?
