Keep in mind, although my engine and supporting components are very capable, I'm still limited by the flow capabilities of the M90S. This blower is its most efficient running 5-6psi, I'm spinning it hard enough to see over twice that on a stock engine. When you over spin them like that, heat as well as the blowers physical inability to move the required volume of air starts becoming a factor. Had I gone with a larger displacement Eaton, or one of the bigger Twin Screw units, I could easily hit 500RWHP with very little fuss.
Even with my upgraded heat exchanger and coolant capacity, I'm seeing upwards of 190* air charge temperatures.....which is quite high. Keep in mind though, this is on an 85F day, with 68% humidity, but it's still high regardless. Were I keeping the car, I'd probably adapt some sort of water/methanol injection set up into the system and would likely pull another 50RWHP out of it, but as long as I’m able to make a few good runs with her and knock down some decent times, I’ll be happy.
We'll see what it makes when I've got the fuel pump installed and sufficiently cooled the engine down, but I doubt eclipsing 400rwhp is a reality. Especially considering I'm in the 20-22% drive train loss with the combination of the Automatic Transmission and Independent Rear Suspension.
I took a couple of video clips of the dyno runs, but I'm gonna wait till she's seeing decent numbers before I go posting them.
...oh, and they replaced my AWSFA12C's with a set of standard TR6's gapped a .032 and everything works just dandy.
