I feel bad for you buddy. So much down time and now the bearing. Hope everything works out for you. Your one patient guy. PS: Great numbers on 18psi. You almost made as much as me with my old TD05 setup at full kill :)
:This is a day of good news/bad report.
:GOOD NEWS:
:We made 529.9 rwhp and 443.9 rwtq at 1.05 bar and 573.8 rwhp and 452.5 rwtq at 1.25 bar. This was all at 15 degrees of timing and an air fuel ratio of very close to 11:1. Additionally, we had a 50/50 mix of race fuel and super unleaded for extra protection - did not want any costly mistakes. It was 95 degrees at 4:00 p.m. here in Austin, but we did cool down pretty well between runs.
:**It is worth noting that the FMIC never even warmed up while boosting**
:Because of my wastegate springs (.8 bar with boost controller off), the most I could make on the dyno was 1.25 bar. I'll come back next time with some stronger springs so that we can run whatever boost we want. Additionally, on the Supra these turbos give 20 rwhp with each 1 psi of boost and this appears to be consistent on the VG motor as well. If you take the numbers out, 28 psi should equal 775 rwhp; equivalent numbers that are made on the Supra.
:I did want to give a special thank you to Aikmeng Kuah for coming over and putting in a fresh set of spark plugs as well as bringing a consult (BIG thanks to the Austin crew for letting us borrow this) so that we could keep an eye on injector duty cycle, etc. The data logging feature is very nice.
:Here are our results:

:BAD NEWS:
:We developed a rod knock. It is small, but it is there. I left the car sitting on the dyno after we finished as I do not want to risk any further damage.
:We are going to pull the motor out in the next week or two and take a close look at whatever issue may have caused the problem. If possible, we will identify what the issue was and make sure that the motor goes back together with a close eye on clearances. I am somewhat concerned as I know Mike Willemson with TD 05's on his car had two motors built at the same machine shop and both developed a rod knock (one at 500 miles and the other at 2,000).
:I feel very confident that detonation was not a factor during the dyno pulls because of the good octane, good fuel supply, conservative timing, and conservative boost.
:Also, I do not feel that the 7,500 rpm pull did us in either. The TD 05 motor we previously had saw 7,200 rpms on a regular basis and never missed a lick.
:That's it gentlemen!!
:On we go.
