AR Fabrication hosted a free dyno day on March 6th and 7th of 2004. Here are some pictures, notes and videos of the event. First the MR2s! Click pictures to enlarge.
My car's dyno graph. Relevant modifications were:
Apex AVC-R boost controller set to 1.25kg/cm^2 or 17.7psi of boost.
Supra 550cc/min injectors
Apex AFC with minimal tuning - taking out only 4% of fuel in the top end.
3" custom exhaust - no secondary cat - primary cat gutted.
K&N FIPK (intake)
Stage 2 water injection kit with 3GPH and 5GPH nozzles.
PT Upgraded CT-26 using a T04E-50 trim compressor.
One interesting item was that I measured the HP with the GTech the night before and it was showing in the 240 to 246HP range. I'm very happy with how accurate this device is. The weight entered was 3080lbs - so entering a slightly less weight should increase the GTech's accuracy.
Doug on the dyno, and results. I believe he was running
a T3/T4 with the T04E-50 trim compressor at 11psi of boost, external
wastegate vented to atmosphere (loud!), and on the stock fuel injectors.

Randall's runs - He was running a T3/T4 with the T04E-46
trim compressor, a larger bore (not sure how much - think it was a .2
over?), boost set to .5bar or 7psi, and stock injectors.
