Re: Most Powerful S4R/S4RS Testastretta

Grazi posted his S4RT dyno results last year. He has full Arrows, open box and a PC3 with a custom map resulting in 131.6 at the rear wheel. You can see his results here:

I remember his post because I got the same setup and the same guy wrote the fuel map but I only got 130 RWHP. I'm not sure what else could be done short of custom head or valve work. Either way, better performance results can be found in suspension or final drive at this point. I'm considering a lightweight flywheel but I'm starting to think I'm overdoing it.

Chris at Desmoworld got 140+ rwhp out of his. Claims it's just a Spark exhaust, PCIII w/ custom map and some 'engine optimizing'.
