viper triple xxx, here ya go
Viper XXX, nah, you didnt piss me off, just gonna make a point and use your common stupidness as the example of why people think they know whats gonna happen and they have no factual expeirance to back it up as in your case. You already inserted your foot in your piehole, posting for Jeff on his sale forum...lmao, I thought you talked to him already....lmao!!!!! Time for school clueless............
The engine I posted an example of is the exact cylinders as delivered from Hauck with his 10,200 rpm pipes, I said it was mine to make you think a little more, Anytime you raise the exh. port of a 2 stroke you raise the powerband of the engine.. RIGHT?? , so the 29mm exh port would have been all you really needed to see to know it was a high rpm engine,(or so youd think) along with the extra kicker of the raised transfer ports! Junior was at least able to pick up on this, and didnt come too far off of the REAL WORLD DYNO RESULTS!!!! not your so called common stupidness results.
This motor on the dyno made 158.9hp at 10,200rpm and the very low torq output of 90ft lbs, and the funny thing is that the torq. output was low all the way from the beginning to the end, starting off even lower at 60 and going up to 90. After jetting the sled down as the air/fuel ratio seemed goofy fat and lean, it bounced all over the place, still no significant gains could be had. So we sat back and thought about the factual information in front of us. In order to get more from the pipes, the stingers would need to be tightened up and the motor would need less transfer timing and maybe a lower exh port to work with these pipes.
So, we installed the Bender pipes, now these are DESIGNED to work at 9200rpm there viper xxx, so they cant work anywhere else right???...lol,
BAM.... the motor picks up to 167.3 hp and the torq. jumps to 99ft lbs, now we are getting somewhere, so with some jetting changes , a mod to make sure the carbs are not vibrating with the solid motor mounts being strapped down to the dyno table, we pull another run....wham 172.3hp and 104ft lbs of torq, but guess where it made the power.....................at 8700rpm, way,way lower then the 9200rpm, revving it up to 9200rpm only yielded 171 hp but the torq dropped to 99ft lbs. Wonder where we clutched this sled to run then.......lol!!! Put that in your pipe and smoke it triple xxx, these are REAL world results, not common stupidness you have, so until yamablu puts it on the dyno you dont know whats gonna happen, and with changing the entire timing curve, along with the powervalve opening curve,bigger carbs,port timing changes, compression increased, its not gonna be like the stock original is gonna be. All along I have said put it on the dyno, and you want to argue you know its not gonna work because the pipes are designed to run at 9100rpm, well youd most likely be wrong but again, so who's the meathead now?? have ya looked in the mirror lately.....
Viper xxx, ok , now that I have had fun with you I quit, just had to prove a point that once you change 100 things, the only way to know what a engine is gonna do is dyno it, and most of the time youll find out that the engine takes on a whole new attitude now so you cant go off of what the pipes say, the porting guy says, etc. Cheers-
One last thing, the rx1 and apex engines run the clutch speed at 8500rpm because thats where the clutch is most efficent, the higher you rev them the less effeicent they are, just a bit of info from the yamaha engineers. Peace
