RCC Stage 1 Turbo With 240 wheel

[Mr Bogus]

kind of an old thread but Ape_man_escaped made I think 251rwhp @6.5psi w/jackdrive and 240 tire.. Density altitude was probably around 1000' at Ryan Schnitz's shop

I think his was tuned in the mid 11-1 A/F...

He recently stepped up to the 12lb spring and ticked off just a hair over 300rwhp.. (via jack drive)

Lots of wisdom on this thread. Need to either put lower compression pistons in that blown motor or take out some timing as was suggested. I would never tune to the edge for a street bike, it is just not worth it. Good Luck!

Whats up Randy.......It was with a 300 tire, and a 10 lb spring, it was in the high 280's (depending on the dyno u use, could be higher or lower) In the process of doing more changes.................

Take a good look at your dyno chart. You have an amazing near straight up curve in the 5500 to 7500rpm range. That should just about rip your arms off. Talk about serious HP in a 2000rpm spread!! You could do awesome roll ons in street match ups....... That could induce tire spin if your not hooked up well. I congratulate you on a nice HP curve.
