1996 Polaris 680 Ultra SP - PSI ModBlaster Pipes 

Mike, I added my setup in the video description if you click "show more"

I'm still running the factory oil injection. Oil pump is set at the factory marks, I haven't gotten any more in depth than that with it

Thank you. That clarifies it a bit more

No "can". Three individual pipes. They make more power, not just noise like a can.

I doubt they still make them. You'd have to find a set used most likely.

Renkotsu666 PSI went out of business. the best you can try is to join some Polaris groups on social media and make it known you are on the lookout. These Mod Blasters are far too loud for trails. they are more so a lake pipe than anything.

I know it’s a link to another video. Same author. Hope it helps. But under a question from ADCBbikes and sleds I listed the setup I ran over 10k miles on. On my 96 ultra-soreass. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-obdNiHX9DYI.html PSI needles if you can find a set, or SLP needles and regarded timing are the key. Along with the factory service update to the carbs for 96 models. If you run SLP pipes remember there are two models. One “tourqer” set of triples. The big part of the pipes. Belly if you will is 9” if I remember right. They like to spin 8100 and load the clutches. Think 10-62 weights not 10-54. The other set of triples has an 8” belly in the fat part of the pipe. They spin 87-8800. PSI had trail blasters and ModBlasters. The modblasters would happily spin 8700 or 9700 if you had port work done. Don’t forget to retard the stator the width of an 1/8th Allen wrench to keep from detonating in the midrange. In 5 motors I set up 11* was the number you looked for at TDC. An 1/8th inch Allen key almost perfectly aligned with the new timing marks. Art Sever at Engine tech had an 800 kit for these too. When they wore out. Iron sleeves to replace the 680cc Nikasil ones or had detonation ,and 800 storm pistons. Still used PSI modblasters and ate XCR 800 or storm based 800s. About 180hp and 1200$ in 2004. Was cheap compared to re-chroming jugs then. Something to watch for as a heads up.

***** i was asking because i was almost going to get modblasters for my ultra, but i came across some dynoports which make more hp so i'm getting those. going to have to cut the carb slides god damn it.

***** i will most definitely show how much faster than srx's and f7's my sled is. dynoports make about half of a hp more than psi's but dynoports have a much stronger midrange. dynoports are 102 db just like the most blasters. 149.2 hp on a stock ultra with dynoports and modblasters were right behind it at 148.something.

+Jim L it isn't complete, and my ultra engine is in a xlt frame but this is what it sounds like at idle instagram.com/p/BBG1dQJkYXT/?taken-by=frankiejames7. i will upload a video to youtube once i get the clutching dialed and swap it into a proper ultra chassis

Frankie, I've seen the Dyno Tech Research pipe shootout article. the PSI Stage II Mod Blasters made more power. 150.0 hp with shaved heads.

i have it. those yamaha drivers don't like it very much

Not a ton as I have other sleds, but yes I do ride it. Quality miles, not quantity.

I'll keep it in mind but I'd have to put you on a list ha. I've gotten a renewed interest in this one this year if I find the time
