Thumbs Up Gus M Joins the HPF Stage 2 "6766" Club - 692rwhp at 15psi

Yes, you read it right. 692rwhp with an HPF Stage 2 running AEM. We swapped in the new Precision 6766 turbo and turned the boost up from 13psi to 15psi on Gus's brutal M3. This car has quite a bit of weight removed and has an amazing powerband. It pulls so hard and so clean. The torque is almost perfectly flat to red-line which makes driving it so amazing. This is the perfect track powerband. Gus has the ECU unlocked so he can make any changes he wants and do datalogging himself. Enjoy Gus.

Holy MOTHER!!! Chris, what would be the cost to upgrade from a current Stage 2 set up to this?

Nice numbers! I assume this is a non-built motor. If it is, how long will it last making that much power?

Congrats Gus, that is a sleeper man. I will have to look out for that beast when up in the OC. Is this new 6766 going in the Stage 1 and 2's now as standard or was this an "upgrade" to replace the original Turbo that came in the previous kits? Either way I don't feel too bad about waiting now...lots of new and good things on the horizon!

I'm curious why you are not tuning the smaller turbo to make more power under the curve? Seems odd peak power is near redline. You could be making gobs more torque and the car would be far more faster in ET's and track times if you shifted that power band left.

I like how his car looks stock, yet it's insanely fast.

Congrats! We added 5 extra gallons of race fuel to the car for you today.

faelar... Below is your previous cars dyno graph at 30psi. Your previous M3 is hitting peak torque at the same rpm as Gus's M3. There's no magic tune that will shift a powerband to the left. Turbo sizing and compression ratios are the main dictators for this. In your dyno graph below peak torque is dropping a full 200 ft-lbs from 5,500rpm to 8,000rpm which is why your horsepower drops off after 6,500rpm. Notice your torque at 8,000rpm (@30psi) is the same as Gus's torque at 8,000rpm (@15psi) except he's running 1/2 the boost. It's crazy how running a turbo outside it's efficiency range can generate so much heat that it literally drops the power to the equivalent of 1/2 the boost.

At lower rpm where the car is starting to respond to boost, notice your previous M3 was down 50ft-lbs of torque at 3,000rpm from Gus's. At 2,500rpm you are literally giving up 90 ft-lbs of torque to Gus. This is where cam tuning can seriously help throttle response and low rpm power generation. The only point at which your powerband surpasses gus' is where you run more boost than him.

We've seen over 50 of these 67 series turbos die for various reasons. The main one is over-boosting as the efficiency falls off and the turbo gets glowing hot. This is a great powerband for a 9 second drag race but not for a 4 hour hot lap session at the track. Running these turbos full throttle at that boost level will not survive one track session. Back the power down to 700rwhp in the 67 and it will last all day and night.

We are using this turbo standard now on all HPF stage 1, 2 and 2.5 turbo systems. Any HPF Stage 1, 2 or 2.5 M3 owner can swap to this turbo without changing their tune. Just be sure to also order our turbo swap kit that includes all the studs and gaskets.

A long time.

No warranty on the increased boost maps. Anyone can also unlock their AEM EMS and turn the boost up themselves. You can swap the turbo though and retain your warranty.

Question on the turbo itself Chris, was this done with the journal bearing or the ball bearing center?

Definitely good to know Chris, thanks for the info....
