RNBRAD Posted January 27, 2005 Report Posted January 27, 2005 Scientist just do not test once and then make conclusions, they do it hundreds of times. Not too many scientist frequenting this forum testing motors or testing motors period for that matter. Builders and tuners do that and it doesn't take hundreds of dyno's with each mod to see and confirm a difference. The results should be the same assuming all variables are exact no matter how many times you do it. Quote

skykingcory Posted January 27, 2005 Report Posted January 27, 2005 That is an impressive difference on your engine. Those rockets should kill the cpi's in a drag. The peak hp on the cpi's in your occurence dropped quite a bit when they should have peaked and then went back up again to the peak hp. Not what you want when racing. Should have kept climbing and peaked, or at least flattened out instead of dropping down that much before picking back up. So many variables between different engines can make different results.

Minkia38 Posted January 28, 2005 Report Posted January 28, 2005 dont believe the dynos? Try a set for free! just email me - if you pay shipping, ill send you a set to try dyno them, install them, pose on them, see if they fit on your blaster... whatever you want to do... if ya like them - buy them if not - ship them back easy as that cant get a much better guarantee than that huh? www.rocketpipes.com Quote

Ducman Posted January 29, 2005 Report Posted January 29, 2005 I think the dyno can find and/or almost create flat spots in your HP curve because the dyno puts a different load on your motor than what it sees when you are riding. You cant spin the wheels when on the dyno which I think a fast spin-up of the motor can help it create more HP. Its like if you have a fast car, doing 50mph, you don't shift down and just roll on the throttle and hold it on untill you max out your speed. Even the last part of the acceleration in that gear isn't going to feel anywhere near as fast as if you had been coming up through the gears hard and shifted hard into that gear. When I did my dyno runs we could do things like start real high in the RPM range and slip the clutch and it would show a much higher max HP than if your started at 2500 rpm and rollled into it. I found that the results were very repeatable between runs, numbers just drop a bit as the motor gets hotter. Your first or second pull should get the best numbers. Bassically I wouldn't read too much into the dip in the HP curve on the CPI's. It may be something that can only be seen on the dyno or looks worse on the dyno and isn't even noticed when actually riding. I think a seat of the pants test may determine if what the dyno shows is real and accurate. But I think the test was a fair and accurate comparison and did show that Rockets put out a better HP number than CPI (at least on Loco's motor). And two different pipes will not both respond the same to one specific set of mods and porting. Quote
wingerdingershee Posted February 4, 2005 Report Posted February 4, 2005 what main jet should i run if im running 28mm carbs and no engine work??[/b] Quote

sandman121383 Posted February 5, 2005 Report Posted February 5, 2005 i gotta sort through this. glad someone got a dyno sheet though Quote
BeJay Posted February 8, 2005 Report Posted February 8, 2005 well i think that they are a better pipe but there is no way they give that much more power 40 more horse just seems a little far fetched. but i could be wrong but for real thats thats a little much for pipes to go from 40 to 80hp please why people with build drag bikes with not more power than that.. I aint puttin the pipes down i just dont think 40 more horse Quote
