PowerInc SRX Pipe Results

All pipe temp differentiations comes from the center section temp, if you look at the stock heat shields on any brand snowmobile you will find they are in the center section of the pipe, not the headpipe.

low center section pipe temps will result in low operating rpm!!!

Well, I didn't have nearly enough to go around the centers of the pipes so I just did the fronts and the center of the main pipe that catches the wind from the hood vents. I suppose any help is better then none so what is done is done.


As for the 125 out of the stocker, that is impressive and I have a hunch that if my sled still had the SRX lower suspension in it, I would be right around there if not higher. Lowering the sled front and rear has to add 2-3 MPH right off the bat. Thanks guys
 
Matt.That's all the wrap I had I had threw a bunch out a year ago or so off my hauck pipes.
 
next time you go to the lake, take your stock pipes with you. if you have a set, if you use stingers with them, cut the manifolds. try them on the same day against your pi pipes.
 
I am intending on bringing my stock pipes with me the next time I go out to ride. I will test them with a radar gun and RPM's and the whole deal. Only problem is that with the stock pipes, I have to change my jetting back to 146.3, 145, 145. The Jetting I am running with the PowerIncs will be way to rich. I will keep you all posted on the results.
 
K guys, got the results back with these pipes. I ran these on the same day and tried to do the swap of the pipes and jetting as fast as possible but did all the work out in the cold. The change of everything took me about an hour and 45 minutes and the temp outside had changed from about 27 in the morning to 31 when I got the second setup done. The lake conditions were at the same distance in the exact same location and same lake conditions so the numbers were pretty accurate. The first runs I did were with the power inc pipes with wraping to keep the pipes nice and hot (I change the location of the wrap in the center). I was running about 3000 feet just to make sure I was getting my top speed right. The track was fairly well packed down snow aswell and I was running a 1" predator track with 144. First run with the powerincs I pulled a 117 on the gun coming through at just about 8550 RPMS which was too high. The second run was identical to the first. I regret not changing the clutching out now to get it down another 200 RPMS but whatever. This was done at 27 degrees. Then went and changed my jetting and stock pipes back. I warmed up the stock pipes a little then I went through in the same location when it was 31 degrees. First pull I got a 116 at about 8450 RPMS which was pretty much perfect for those pipes. The second run I pulled off a 117 just as the Powerinc's had gotten.

I guess the fact that I had not changed out the clutching at all running the same pipes shows that the Power Incs were putting out just a little more power. The bottom end of the Power Inc's also proved to be a little more impressive then the stock pipes as RPM's were reading about 100 higher with the Powerinc right out of the hole (8600 as opposed to stockers at 8500). I am very impressed with the performance of these pipes and I believe it was a great investment. If I were to clutch for the Power Inc pipes the same day to 8350 RPM where they make their best HP I bet I could have pulled off a 118-119 on the gun but I just know that they are running a hair better then the stockers. There are all those other gains to the pipes such as weight and sound too.

Here are the pictures of my Mag and PTO spark plugs after a WOT shut down with the Power Inc pipes. I can probably go down one jet size across the board if necessary but they look pretty good to me.

Lastly, here is a clip of me going around a plowed ice track on the lake just showing you what it sounds like. Thanks
