This is before the turbos go on though but I believe if you can make it flow like this in NA it should behave similar when FI, just like the stock motors power characteristics dont change much when you go FI (ie power still drops off ruffly past the same rpm, albeit at a higher hp level). Changing to the rev-up lower intake manifold is also a requirement to make power all the way to 8k, not to mention strong balanced internals and complete valve train.

please post dyno graph!!!!!

I have requested my first dyno graph over rpm, its currently in kph. Ive since changed exhausts trying to free up some more flow in the top end, which it has, but it has also lost some bottom end from low back pressure, but should be perfect for FI. On the road I can feel it pulling all the way to 8K, I will get another dyno tune and chart when im done road tuning it.

will be anxiously aWAITING...to date, i have not seen anyone post a graph showing power to 8000rpm, even power past 6600rpm, for that matter

My last dyno with scott's cams makes good power, hp flatlines up top, but i was only runnign 12 degrees of timing...I will get another graph with 14-15 degrees at redline, i suppose this will bring the power up and slowly climb to redline...but like i said, haven't seen it yet
