We used just shy of 1300 lbs of fuel at 30 lbs of boost at 7000 Rpm. We were dumping boost with the ams 1000. It will make more . This will be enough to start with . Cant wait to test

I posted this over on YB:
The FC of 1300 was with no timing and a low AFR in the low 7000 rpm. Blower was only spinning in the 50K's.
We were using the AMS as a dyno tool to limit boost with successive dyno pulls. The last dyno pull setting was "open at 30 PSI"
As soon as we made the hit the intake manifold went straight to 31 PSI and the WG opened and instantly dropped boost to about 21. I will tell you this, using a WG to control boost on a setup like this will not work at the track. It bleeds to much boost too fast and does not recover.
The next dyno pull was to be with the AMS set to 40 to keep the WG from opening but it was late and running low on fuel.
We do not know what the max boost would have been. We do know that with the exception of the blower funnel coming loose everything went great.
We have plenty of headroom for increased power. The setup makes power. We need to get to a track to dial in the suspension etc. We have come a long way to get to this point and are more than satisfied with the results thus far.
