I just read a about a company called "Ron Wood Racing" it's been in around for 20 years and did the mods for the Rotax BMW motocycle where the DS engine started from.The companies kit includes of a pipe,cam,piston,ignition and carb,and claims a 50% hp and 100% torgue increase! sounds dangerous.

 

Does anyone know what the SAE corrected HP is at 3000 RPM and the peak HP at around 6500 RPM, for the Ron Wood Stage One Kit? I can't seem to get a straight answer out of them guys. I'm trying to see how much low end gain they are getting compared to other pipes/kits. Also, I want to know the increase in peak HP. They tell me that the curve no longer drops off at the top end, but that doesn't tell me how much the peak HP was increased.

 

Got my questions answered today and ordered the Stage One Kit(49 HP 6500 to 8300 RPM). They are waiting on the 2nd batch of pipes so it could be a week or two before I get the kit.
