That would be a last resort I have 2 working 95 xp800 mpems thanks though. Sorry for the hijack matt
 
I've got a 95 ape available

There you go. No problem on the hijack bud.

I'm looking for colored line that can get here quick. I need 3'8" yellow, orange, or purple. I need the same thing in 1/4". What do you guys think? Where is the hook up?
 
Matt did they make a rev limiter /water injection combo controller for a 95 cdi?

Gary made one in the MT brand but I've never seen one he made for APE(Arizona Performance Engineering).

 
-Yeah I don't have any rev-limiters. I have one 95' XP 717 mpem/box , and one 95' xp800 mpem/box. Not one of my skis has anything aftermarket on it when I bought em ugh.

How does the rev-limiters work? Can you install them on a stock ski to get higher rpms there for faster? Or is this just a small part of the puzzle?
 
Thanks for the tubing link. I gave up on fancy and flashy when it came to that. I realized I needed to attach hose to the areas that will soon be hard or impossible to reach. I like oem water line anyway so started attaching good used lengths to the cylinder drain, exhaust outlet, case cooler, and lower rotary valve chamber.

Yeah the rev limiter just allows the engine to rev higher. It does not cause the engine to rev higher although some models allow you to adjust your ignition timing. If you advance your timing a couple degrees then it may rev quicker and feel more responsive overall but then you run a risk of creating engine damage.

I had to give up on using those RAAS pretty blue silicone engine mounts. I could not get the rear of the engine down for alignment so I dug the two rear mounts back up and noticed that they had shaved the bottoms of them. I need to put the pipe in before I bolt down the aligned engine because that's how it has to be with these one piece aftermarket ones.
 
Glsohio... no rev limiter bump is for built engines spinning higher rpm. Zero advantage on stock. Rev limiter functions as a control for out of water free spin. Its a engine governor, strictly engine protection.
 
More "custom" problems.The Coffman pipe is too fat and does not fit. It's pinched in between the deck and the engine and it's also blocked by the engine mount bar.





Then I went back to the TNT pipe and it allows the engine to bolt in but there is no clearance. I have another TNT that I could pound in but I have to have it repaired first because it does not pressure test. Perhaps I'll just pound the Coffman in, had to sleep on it first.





At least I've got my alignment dead on.

 
You need to heat if first otherwise you'll risk breaking one of the welds the Coffman is a dry pipe correct? And made of aluminum plates welded together like the twin pipe on mt rxx?
 
Yes changing the shape of the chamber could result in a performance loss. Guys have to bash in the Factory Pipe chambers when putting them in HX's with 787 conversions and surprisingly there is no performance loss. I guess it's just the luck of the draw.

I think I have found a "bash free" solution though. I got to thinking about the smaller and lighter Coffman that Mpower was selling. I thought it may still be around because it was missing the coupler/adapter piece that bolts to the manifold. I PM'ed him and he still had it so I'm gonna try it before I damage the others. If I can't squeeze impressive performance out of it then let the bashing begin.
 
I think most of the performance comes from the upper section and manifold on the pipe. The bottom is just an expansion chamber. Are you running a fpp mani or stock mani matt?
