This engine has CP pistons and rings that are 11:1 (approx)
The exhaust side of the head was cleaned up. (ported)
The cams are from a S38 B36 M5 engine (E34) and are at factory settings. No retard or advance.
Stock rods, crank and valves.
Euro headers.
Miller MAF and tunable WAR chip.
UUC exhaust and VSR1 Cats.
Stock ignition, injectors and FPR.
With the high compression we had to remove some advance from the GENII Miller MAF chip to prevent detonation.
But because this engine breathes so well the output was right near my target. I was hoping for 300RWHP.
As you can see from the Dyno graphs I got 294.57 RWHP and 258.42 torque.

This was on a Dynojet at Balanced Performance in Sugar Hill GA and was tuned by Ed Senf a professional tuner that is currently the tuner for the Rum Bum BMW Continental Tire car. Has also done Bimmer World and some Turner BMW's.
The drivetrain loss percentage they use for this vintage BMW and the Dynojet is 17%. Run those numbers and you get
344.64 HP at the crank and torque is 302.35
I'm pretty happy with that for a normally aspirated engine.
This is really just an M88 Euro with better pistons and some head work with modern maf and tuning.
Here's the link.
You are hearing the UUC exhaust too.
