Actually, I use a larger crank pulley and powerpipe to help up the boost a bit but I am still using the 6lb pulley. Anyway, I have posted this on some of the other sites but it's just for anyone interested in what a small Powerdyne is capable of. This was my best run of three the other day.
400.3rwhp/386.3rwtq SAE corrected
I hit these numbers without that last minute fuel spikes that a lot of graphs get. The curve was nice and smooth, hit the 400 mark and then the power fell off about 6100rpm.
Again, not bad for a little Powerdyne. Time for the track.
