RE: Hunter Twin Build
Ok so here's some motor info I'd like to run past you guys. Got this from Tony at WareHouse concerning an inline option:
"I have spend over 40 hours testing it, and am ready very soon to
market it. I designed a "clutch" coupler so there is not a direct drive from
engine to engine. I found that the direct drive would not last for more than
a couple hours at best. I tried most on the market and every one failed
within the same time frame. I urge people to put these manufactures on the
spot with the question, because not one I tried lasted. You would have to
get the alignment to: 0.001, possibly 0.002, and Zenoah holds + - 0.003. So
if I made the coupler exact, there would still be discrepancy between the
two engines. At RPMs of 15,000 the work related heat is so intense
(deflection at 180 degrees), that the couplers self-distract pretty quickly.
Once they begin to wear and have "slop" the system fails on a rapid decline.
The great thing about a centrifugal clutch is, they are designed to
oscillate.
Our system works very well. You simply start the forward engine and throttle
up to start the rear engine. You get a direct lock-up at about 7000 rpms.
The odds of retrieval are greatly reduced, as you can re-start a dead front
engine, or come in on either if one fails. "
Twin clutches? Weird. But how he explains the details it makes sense. And knowing Tony I don't think he'd let anything slide by that wasn't tested tried and true. What's everyone think? Matt? What's your take on this bud? You've run inlines before correct?
