HPF M3 Leaving for MFest3 - Dyno Results (840rwhp) - Carbon Fiber Engine Bay

[HPF Chris]

JP, John and ChrisK did an awesome job getting the HPF M3 ready for the race track at MFest3 (with a little time to spare. :)). They were able to get more power out of the HPS76 at 32psi but that was maxing the turbo out, so they tuned it conservatively at 30psi and created one of the best dyno graphs I've seen on an E46 M3. At the new high boost setting (30psi), once you're at the top of the powerband, hang on because you're going to feel 840rwhp until you let off the gas! At the track we're going to run the low boost setting at 650rwhp during the 30 minute sessions for durability reasons, but I may try to squeeze in a few 60-130mph passes with the VBox at high boost!

Here's a picture of the engine bay with our new carbon fiber parts on it.

Here's a dyno graph (Check out the High Boost powerband at 30psi!!)...

no rpm marks on the graph? looks like a lot of powerband you can not use.

Nice peak numbers tho

That's a 4th gear pull starting at 30mph. Generally people only dyno in 1 gear, usually 4th or sometimes 5th. Unless their car is much slower they will sometimes dyno in 3rd.
