What is the story on the 15 ml rotary pump? Can you put a 15 ml head in a worked over housing that has a 13 ml in it now? Word is that they aren't reliable, what happens? Are there any 14 ml out there or was that just a after thought? The rules say we have to stay rotary or I would just change to a inline.

Just go to an inline more room to grow and more reliable. There has been problems sticking the plunger in the big rotarys.

I had a 15mm hyper rotary pump and loved it. I was told if you get a 15mm, make sure it is a big nut pump. It was open rpm, so the idling around the pits sucked, but besides that, had great luck. I would recommend you get a 15 mm pump, and not try to put one on a 13 mm pump.

I had 550 cc's out of mine. I would only recommend Hyper on this pump thought. I bought it used. You can find used ones anywhere from 3,000 dollars and up.

Just my 2 sents on it, last time i talked to hyper it was over 600cc of fuel and it was over 6000 brand new. Dont buy a used one your gonna get trouble 9 times out of 10. Try to stay away from the 14mm There was alot of problems with them locking up. The 15mm small nut is a great pump also you dont have to go with the big nut. The small nut is exact same apperance as stock which you may need not sure how exactly your rules are printed. Good luck!
