So friday I finally did get a chance to visit the dyno. Had a strange feeling it wasnt going to go well for some reason. Keep in mind the only thing that changed is the header back exhaust system. First pull was 390rwhp...... ouch. New exhaust lost some power and was richer than before. After a re-tune it was up to 405rwhp, which is still 30hp down. Figured I would post this to show that its not all fun and games going for more power n/a. They are very sensitive engines and all the details count. No big deal, the new exhaust needs some tweaking and the power will be back soon. So here is the chart to show the stellar losses 
Yeah it would make power to 11k, might make power to 12k. At its current setup it cant make MORE power after 10k, but if the intake was shortened further then maybe it could. I have played around with the idea of putting a center bearing in the engine and make it capable of 11.5-12k rpm but that is on down the road.
Yes the ITB system is almost done, and then testing will start.Yep, should have even faster throttle response which is already extremely fast. Here is a teaser pic of the semi p-port slide throttles

Thanks Brent 
Currently it is at 250rwtq, and even de-tuned can run it right there. Many intake and exhaust revisions have been going on, and maybe 260-270rwtq is possible. But not much more. Basically the ST2 setup will have tapering torque after 7k, yeilding 300rwhp from 6500-10k. I will most likely stay in ST2 all the time. I like the idea of entering ST1 periodically to give me a reason for high horsepower development however. Danny Popp is a machine, wont be seeing the rear end of his car any time soon!
I do have some videos but not worth posting yet. I want to take good vids of the next time out though!
