You're running the 80mm pulley (middle one?)? If so, I think those are pretty good gains. 50whp and 38wtq is pretty nice gain for running the same size pulley (roughly, but still larger) that you had on. I'd like to see the graphs when you are able to upload em.

yes, dyno was the same dyno
IAT2's were about 140 a wot at the end of the session
next is some cooling mods, h/e coming soon....and I can probably up a degree or 2 of timing...300 is very possible
it's the 75mm pulley

140 is very good for no cooling mods and being on the dyno for 2 hours..!

88% what afr were you commanding?
Still debating on 60# or 79#, I don't know if there are any disadvantages to the 79s? Such as tuning difficulty or having to upgrade fuel system.

Very nice numbers! Congrats, and I know you will hit 300+whp with a couple more tweaks to the tune easily. 
I find your data interesting in comparison to my twinscrew data from back in August since you are on the same size pulley I was. The IAT2's were right where you're at and all I had for cooling mods was the dual pass plate. Also, my IDC's were right where you are at as well at 87%. I had a little more timing and made 272whp, but with my 2.6" setup I made 236whp on the same dyno. You have pretty much made my day with all your info. Thanks!

well, the tune probably has 300 in it easy.....fuel is nice and steady now, only thing left is maybe a few degrees of timing to see what happens, not to mention the nice h/e I have going on......but there was a very nice increase over the m62 w/ the 2.85
