I think they exceeded our recommended boost level on the dyno. My car made ~600whp at 13 psi on a Dynojet. Stout numbers though!

First and foremost I think Maxpsi and Nick G took a big risk on the e46 m3 market and we appreciated all their hard work, this kit seems very promising

I noticed the video mentioned Trapping 115mph at 650whp on street tires now i realized he said 1000 altitude too but this doesn't add up

Mike had mentioned to me that they were running a different clutch than the one Maximum PSI recommends and they were having issues with it on the track and drag strip.

I definitely can't wait to get my car to the track and drag strip next year and see how it performs!

I think it's 1000 feet of distance not altitude which would be about .18 of a mile. This would account for the lower trap speeds.

They even mention in the video next year they hope to do a proper 1/4 drag race.

exactly .18 which they then accounted for by increasing the boost some more. But this still doesn't account for the lower trap. If a ess z4 M which I am sure Toan@Platte AG was running at a stage 550+ vs the regular 525 ess production kit is trapping 107MPH. Then, a 650whp car will not put down 115mph on the same track. There is no arguing this, there is a difference of approximately 150whp+ (easily) between the two cars. I am willing to buy the clutch issue because something always breaks at the track on someones car, but 1000ft will not make a 650whp car run a 115.

I'm not arguing. I was just correcting your post 1000 feet distance vs altitude. Which would account for a lower trap speed than you were expecting.

Hi guys, here to answer some questions.

First off, yes, it was 1000ft, not 1320.
Second, at the time, I was running a Spec stage 1 clutch, this luckily held on our dyno run but soon after it began to slip badly. To further add to issues, our eBoost 2 electronic boost controller failed, giving inconsistent boost levels.
example: I'd run off the line, spinning in first, managing it and seeing around 7psi, I'd shift to second and see only 4psi, shift to third and randomly I'd see 10psi, then going into 4th I'd see 3psi. This led to a hell of a hard time getting good results out of the car, mixed with the slipping clutch and street tires.
On the third day I was able to source a manual boost controller to get the boost at a reasonable and more predictable level, though still it was far from ideal.

As for the bloated dyno numbers, the car was bolted to a Dynapack hub dyno. This dyno happens to read extremely high. We did see higher boost levels to the change in load on the very first run. What was set to be 13psi ended up being about 14. The car was a bit lean up top, but still, we recorded 647whp. Days before, we were on the DynoJet at EAS and the car made 589whp on 13psi with 105 octane. Far more reasonable of a number.
