stroking Posted February 28, 2012 Report Posted February 28, 2012 Makes me feel better thank you. it shouldn't !! because the loaded version is the correct one thats what your motor will be making when riding Quote
Snopczynski Posted February 28, 2012 Report Posted February 28, 2012 it shouldn't !! because the loaded version is the correct one thats what your motor will be making when riding I love how I stated it was a loaded run 3x, and somebody still freaked out. Quote
Titan up Posted February 28, 2012 Report Posted February 28, 2012 Thank you for posting those graphs, very interesting. If I was to do a serval, I would 100% be running PC's on it, just based on those graphs. I'll go out on a limb and guess that the PC's would be 7-10hp in some spots above the Shearer's from 6k-8.5k, where most people ride. Quote
Snopczynski Posted February 29, 2012 Report Posted February 29, 2012 Has any of the builders in the industry tested the Pro Circuits on their dynos with the Serval against any of the other pipes they are claiming are the best yet? Anyone know? When I did it, and I talked to people about it, all the builders acted like they were completely disregarding the factual numbers I came up with on the PC's. I am willing to bet no one has actually tested them yet, and they are assuming off numbers they have seen from all the popular mid-top pipes out there. Quote

From what I've seen you and I are the only ones that have posted any dyno results for the PC's. I've seen a couple people say they are running them, but I dont think anyone has done the comparisons like you and I did with my bike. Quote
J.J. Posted March 1, 2012 Report Posted March 1, 2012 Hi Snop, 05, PC's are also preferred by a few here in South Africa and the original thread that you guys posted up showing the loaded runs last year is often referred to and very much discussed. There are still a few who are skeptical, but there is not much doubt that for the set-up used in THIS case, (28mm Mikuni's etc) the PC's dominated the run. As far as I understand, a huge benefit of doing a loaded run is that you can accurately determine the A/F ratio across the throttle range which should translate into improved performance in real world riding conditions. To give added credibility to your runs, would it not have been possible to confirm a base line A/F ratio for each pipe tested, just to prove that one pipe was not better jetted than the other? That way there could not be any argument about the issue. From what I have heard the A/F ratio is not easily plotted on a graph same as Torque and HP? I would love to see the results of the same run with 33PWK's! cheers & keep up the good work! J.J. Quote
No Limit Powersports Posted March 1, 2012 Report Posted March 1, 2012 Just to clarify when you say loaded vs unloaded im assuming you mean using a load cell. A non load cell run can be properly loaded if the operater knows how so I would like to know what the gearing was on these runs. Not questioning your runs at all just curious. Quote

Snopczynski Posted March 1, 2012 Report Posted March 1, 2012 post up some of your runs with shearers and cpis with big carbs for comparison... It isn't going to matter what the shearers with big carbs did because he is going to have unloaded runs ran on a different bike on a different dyno, in a different area of the states. The only thing that will matter is if the pipes are tested on the same bike, same dyno, same day, same conditions, same loading. It was ran on a dyno with a load cell, the operator does know what he is doing. It was shanes bike, so I dont know what the gearing was. Quote
No Limit Powersports Posted March 1, 2012 Report Posted March 1, 2012 Unloaded runs not loaded properly will yield results like you seen but as if the unloaded runs were loaded properly then a load cell is not needed for a sweep pull. Typically loaded or unloaded runs should make no difference in power unless the pipe is not building heat and the run is too short that is why i ask how the bike was geared. My question has nothing to do with your results I was just curious why the power dropped so much with a loaded run. Quote
Snopczynski Posted March 1, 2012 Report Posted March 1, 2012 At this point comparison wise it doesn't matter wether the dyno was loaded or not, someone is going to have an excuse for everything until they run them on their own dyno. I was hoping in the months upon months that I had been gone, someone had finally manned up and ran a set of pro circuits against some of the nuthugger pipes and finally got some results. However, I guess everyone is scared to find out the truth. Hell I ran the PC's agains the trinity IV's and the CPI's and everyone still had an excuse for the results, so i guess this is never gonna get figured out. It is too bad, you guys are missing out on some awesome low end and midrange power. Quote
Titan up Posted March 1, 2012 Report Posted March 1, 2012 What about Snipers? Werent they designed for the Serval? I rarely see anyone with them The Snipers were designed around the 421 cub..They like high port timings. Quote
No Limit Powersports Posted March 1, 2012 Report Posted March 1, 2012 Ok well i was just asking a simple dyno question on how the bike was loaded. If you understood how a pipe has to build heat then you would no that the bike being loaded properly means everything. I really could care less what pipe you like thats your choice and i'm not defending your pipe or mine this was directed at the dyno charts. Thats really neither here nor there as i was asking as to why your your unloaded runs were so much different than the loaded ones and with a 14/46 gear I understand but if your too caught up in pc vs brand x then thats fine. I will sell and build motors using the best parts possible and what makes the best power for us as it only makes are motors perform better and i am not a pipe builder. I have tested several different pipes on the serval and shearer pipes have been the best from top to bottom. No i have not tested a set of PC pipes on one yet and maybe one day i will when I have time. My dyno charts vs yours really makes no matter as like you said diff dyno diff day ect ect but i will tell you that its not just the pipe on a bolt on serval that makes the pipe work. Quote
Paulie B Posted March 1, 2012 Report Posted March 1, 2012 So which one of you two are gonna run a test with both set-ups the same day with the same bike on the same dyno! Your only 1 state apart Quote
