Need a simple, but STRONG reduction drive setup......

(OP)
Here's the skinny......


13B rotary racing boat engine turns at 5252RPM ONLY!!! Power is adjusted by mapping turbo boost. Need inline(reversible rotation, OK)2:1 speed reduction unit design that can handle 400-500HP@5252RPM. Current units available can only handle about 300HP at the RPM......HELP! Thanks.


RE: Need a simple, but STRONG reduction drive setup......

You may need a custom drive.  If drive is in-line it will have to be at least 2 stages.  Will be expensive and require hefty gears.  Preliminary calcs show 1st stage pinion with 4.9" pitch diameter and 2" face width.

check with Winters Performance (York PA)
they make quick change rears for racing (800+hp) and I think they may have something that would work for you
