JasonsBanshee Posted September 8, 2005 Report Share Posted September 8, 2005 Are there any comparison charts on hp? What would you buy if money was no issue? I loved my CPI pipes but the Rocket pipes look sweet too. Quote Link to comment Share on other sites More sharing options...
JasonsBanshee Posted September 8, 2005 Author Report Share Posted September 8, 2005 (edited) OK, I found a chart on the rocket pipes web site comparing the two pipes. Any opinions out there? Does one or the other sound better or louder? Edited September 8, 2005 by JasonsBanshee Quote Link to comment Share on other sites More sharing options...
stclark816 Posted September 8, 2005 Report Share Posted September 8, 2005 There are many many debates over these pipes. Im sure if you did a search you would come up with 50 threads. But, I guess it all depends on what kinda motor you got. That dyno sheet is Locogato11283's. His motor seemed to like rockets better, but then again, you could do the same thing on a different motor with different port timing and it could go the other way. I chose to buy Rockets because I like the look of them, and not many people have them. IMO I think CPI's are ugly and plain looking and everyone has them. And some people think Rockets are ugly. Just personal preference really, each pipe will react different to different motors. Both are great pipes. Quote Link to comment Share on other sites More sharing options...

odaen Posted September 8, 2005 Report Share Posted September 8, 2005 I run CPI's, and I admit, they are just a plane jane looking pipe, but they are a tried and proven performer, and I really have no complaints with them whatsoever. The only dyno sheet I've seen comparing CPI's and Rockets was loco's, and it's a pretty funky looking dyno plot. Ask 10 builders what they would recommend though, and I can pretty much guarantee an overwhelming majority would recommend the CPI's. Get what you want though. The odds are that they are gonna fall within a couple of hp of one another. Quote Link to comment Share on other sites More sharing options...

Fireman-hott Posted September 10, 2005 Report Share Posted September 10, 2005 Couldn't have said it better myself loco. Rockets usually put out more torque though. Quote Link to comment Share on other sites More sharing options...

The fact that it was a strange plot made the results less credible to me, at least. Fireman-Hott, again, I'm not bashing, but if the rockets put out more torque, then I'd think that there would be more plots showing this. I know people look at HP more than torque, but if you are putting out less HP, but more torque, it just means you are developing the power at lower RPM's. I have no vested interest in promoting CPI's. In fact, I'll be checking out some other pipes next week. But they are recommended either number one or number 2 consistently by builders as the inframe to run. It must be for a damn good reason. If I got a set of rocket pipes this week, I'd dyno them too.

locogato11283 Posted September 11, 2005 Report Share Posted September 11, 2005 damn, here we go again. once again, I wasn't bashing rocket pipes. loco, you just admitted that your dyno sheet looked funky, so all I was saying, is that it's the only dyno sheet I'd seen where rockets performed better than cpi's. The fact that it was a strange plot made the results less credible to me, at least. here we go again with what? i never said you bashed rocket pipes did i?? i admitted it was funky looking, but it was funky looking for both. so i dont see y its not credible?? and forthe record i never said rockets were better for every motor. it just so happens that on mine rockets were better. as far as credibilty goes, rick cairo and jeff wendorff were there that day and they didnt seem to mind the fact that it was funky looking...and they both build real fast shit.. Fireman-Hott, again, I'm not bashing, but if the rockets put out more torque, then I'd think that there would be more plots showing this. I know people look at HP more than torque, but if you are putting out less HP, but more torque, it just means you are developing the power at lower RPM's. what plots? ive only seen 2 dyno sheets i think. mine and wesw...are there other rocket dyno sheets out there?? I have no vested interest in promoting CPI's. In fact, I'll be checking out some other pipes next week. But they are recommended either number one or number 2 consistently by builders as the inframe to run. It must be for a damn good reason. If I got a set of rocket pipes this week, I'd dyno them too. 413742[/snapback] but when ppl talk about out frames, GRR suicide pipes are mentioned quite often...same pipe...

Fireman-hott Posted September 11, 2005 Report Share Posted September 11, 2005 Odean when do you eed them by I can try to get a set to you for the test, even if I have to pull mine off. Quote Link to comment Share on other sites More sharing options...

Fireman-hott Posted September 12, 2005 Report Share Posted September 12, 2005 Its going to have to be bare. I'll see what I can comeup with. Got about 3 more sets to get out and I'm caught up I do believe. At least as far as I've been paid for and know about. Quote Link to comment Share on other sites More sharing options...
rocketboy Posted September 12, 2005 Report Share Posted September 12, 2005 ill tell you guys would would be a really good test is to take a dune ported 350 and a identical 4mill with average dune port timing of 198ex and a 130 transfer with the usual add ons goodies,like vforce 2's ,k&n intake ,33 or 35 pwk carbs ,20cc domes,then get yourself a set of rockets ,cpi ,and shearer inframes and make several runs on a modern winpep dynojet with low humidity and same dyno setup entirely. i and a million others would like to see those results Quote Link to comment Share on other sites More sharing options...
