So with HPF now out of business, what to do for a turbo E46 M3? look inside

Not sure how many of you know but yesterday HPF closed up shop... of course that leaves the current HPF cars without support and anyone contemplating a turbo E46 M3 with one less choice (not sure why anyone would want an HPF kit these days to be honest).

But that's ok... there is a new way to get your fix. I thought I'd share some exciting development coming from the guys at Maximum PSI & guru BMW tuner Nick G.

Let me present to you the MaxPSI E46 Turbo kit... It's truly impressive to see what these guys have come up with so far and impressive to see where they seem to be going with this. It almost makes the HPF cars look laughable in comparison. Of course lack of proper engine management w/ HPF kits (using a piggyback) never works out right on an ECU as smart as the one in the M3.

I thought it's time they got some well deserved recognition outside BF.c so read on!

The guys @ Maximum PSI have now released their Stage 1 turbo kit utilizing the stock ECU, and have done testing on their stage II kit on race gas. Both "stages" are on a 100% stock motor. They're still in development stages for other Stages (like built motor, etc).



Here is a Dynojet plot of their stage I system running on 93 octane, with catted downpipes:


and here is their testing of the strength of the motor for their Stage II development... motor is still stock here, running MS109 fuel at around 17 psi (697 whp / 513wtq).
