Rusty,

check up on the Whipple-charger/KenneBell(for Fords)/Lysholm - they are all the same just different licence takers from Lysholm (I think......).

Very high efficiency - up to a certain boost level a intercooler is not required.

As far as I understand you will have not any boost-pressure problems that would need a wastegate.

It is a pricey choice though....

Subject: [FlyRotary] normalized supercharger? Was Re: Is common sense dead (rant mode on)

I will have a normalized Renesis, supercharged.

Hi Mike,

How were you planning to normalize with the supercharger?

I'm planning to put either a supercharger (what I'd prefer), or another turbo (shut up John <g>) on the RV-3, somewhere down the road. One of the drawbacks to the supercharger is the lack of boost control. I asked the ATI guys about controlling the boost via a valve on the outlet of the blower, but they said not to do that because it was bad to unload the blower.

You can certainly control boost via throttle opening, and perhaps you can even do it via engine computer almost like a sort of rev limit. What's your plan?

Cheers,

Rusty (no flying today, due to work that sucks)
