What SHOULD a piston, pipe,and ported Raptor make on a rear wheel dyno??

 

Mine will be Dyno'd this week in Vegas, I'll tell ya then. Yhe only other one I saw was at 43 RWHP. Doesn't sound like much does it? That cant be correct. Just remember, the a$$ dyno is the only one that really matters since no 2 dynos are the same due to many factors (temp., humidity, elevation, tire pressure, tire size / type, etc....)

Late!

 

74LV, did that one have a cam as well? or only what is mentioned above? What exhaust system did it have on it (if you remember)?

Thanks.

 

Toid, Actually its my bro-in-laws so Ill let him tell ya. Both bikes are basically the same, jetting a little different, I have an e series wb full pipe and his has a r series wb full pipe. Ill let him tell ya the rest

 

Soooo.... Raptor74LV what does your @ss dyno say????

 

74LV, you expect yours to be pretty darn close to the same then right? That's not bad RWHP. I see 686's with just over 50,,,, sooooo, it's not all bad!! I'm happy with those kind of #'s. Like everyone else has said, the ole A$$ Dyno says it RIPS!!![img]i/expressions/face-icon-small-happy.gif[/img]

 

The only way you can compare dyno numbers is diffrent quads on the same day one right after the other by the same operator on the same dyno, & then only if the weather hasn't changed any between runs.

I got 43.1 HP on a stock Raptor with a Sparks X6 & dynojets.
I've seen numbers not much higher than that on built 686's.

The A$$ dyno & a stopwatch are the best ways to tell HP gains.

eRAPTOID, How do you like the new & improved TOID?

 

All I have is a slip-on, Pro Design filter set up, and jetting and I'm at 42 HP. One with a high comp piston has got to be higher than that.
