The Official Dyno # vs. Track time thread!
Buschur Racing in Ohio- MD-AWD-500 @ 369whp = 122mph @ 3325lbs
Interesting.

Good question with an even greater answer. Observe the dynosheet comparison below....

As you can see the peak whp/wtq increased significantly, but pay extra attention in the rpm range that matters most 6,300 rpm's and above. The turbo is out of steam and the powerband falls to the point where there is hardly any gains over my previous 37psi tune. I do not have an overlay with my 34psi tune but I would imagine it would look VERY similar. So yes the peak number keeps going up yet the time did not get lower nor did the trapspeed go up because of the powerband. Couple that with the fact I was also fighting a 14mph headwind last time at the track and in retrospect I was running the car with zero gain between my last two trips out. Peak numbers are only a small fraction of the equation gentlemen.

I can't believe I missed this thread.

Also, if you wanted to note next to Mike from AWD's car, his car made 803 on our dyno when it ran those times too. Be a nice comparison if you can squeeze it in.
