For all of you out there who were wondering about the Power Inc Pipes, I found this for you.

No boys, those are the powerinc srx pipes, those are not for the sx style "redhead" non powervalved triples.
 
Thank you so much Valin, I couldn't find that sheet anywhere. I took a guess as to where to jet these pipes cuase I am running VForce 2 Reeds and I am going to go with 148.8, 148.8, 150. Also, I want to clutch these pipes for 8300-8400. Before seeing this sheet I was going to clutch them at 8500. Thanks for the info. I'll see how fast I can get this sled going! BTW, that is all on a stock motor right? Thanks

Yes, I knew about all of the other dynos and I have had many people tell me before that they did dyno the SRX Power Inc but I could never find that exact dyno on their website, where did you find the SRX dyno sheet? Did you have it saved on your computer?

Also for jetting, I think I might go to 45 for the pilot jets to be on the safe side for low speed riding.

acording to this should i clucth for 8600? every ones told me 8200. but with the pipes running at where they are it doenst seem like much more power then befor. its a sxr 700
 
terret there are two different PI pipe designs for the non powervalved 6 and 700s, the end dumps and center dumps, and both are COMPLETELY different pipe designs, and one result of that is that they both run at totally different operation rpm ranges. The end dumps are the ones shown on that dyno sheet, and yes they like to be run up near 8600 or so. However, you have the center dumps, and they dont like to be run anything over 8200 rpms. So you have yours set up right at 8150 to 8200 rpm.
 
I am getting ready to put a set of end dumps on my MM700, what would be a good start for jetting, I'm running at 0-3000 ft with a tempa flow. Also any clutching changes/recomendations? Has anyone had to do any mods/protection to keep the pipes from melting the cowling or tub?
