Well why not post some numbers? Or a video ?
My KF IV on 21 " wheels 90 - 92 mph @ 2000 '

Contact the people at greenskyadventures.com They have done quite a bit of work
with the HKS/Kitfox combo and can sell you a complete firewall forward kit for
the engine.
When I spoke with them this summer they were still saying cruise difference was
negligible. Take-off/climb performance was the same if you had the modified
kitfox exhaust, but obviously reduced if your 582 was actually making the 65 HP.
I was wondering how long the 700e would be in production with the 700T being introduced,
but they seem pretty confident that HKS will keep 3 engines the 700e,
the 700T, and a possible future engine which is the 700T without the turbo-charger.

I've got an HKS but am not flying yet. Mine has the 3.47 gearbox which
isn't ideal for the Kitfox but it was on the used engine I bought. I
have a 70" three bladed Kiev which is a combination that performs well
in the Skyranger. There is a Super Koala flying with the same combo but
I can't get any real numbers. A guy with a similar setup in an Avid
(Apples and Oranges, I know) gets 95mph cruise.
The HKS will produce 60 hp and maybe a couple more with the right intake
and exhaust system (I think the short rear intake produces more power
and the exhaust needs big long pipes). The 582 as installed in the
Kitfox loses a few hp (without an exhaust mod). So an HKS swap is
pretty even. The all up weight is within a pound or two. The weight
does go a little more forward due to the loss of the belly radiator.
GB's plane doesn't have fairings on the LG or struts so it isn't very
fast. He could gain 10mph with some work.
One thing I would like to do with mine is to actually use the NACA ring
cowl for what it was intended: a pressure cooling system. It has that
massive forward facing hole so use it to pressure cool the cylinders,
oil cooler, and pressure the carbs. Basically use that big intake for
everything and provide a low drag exit ramp. This was one of the tricks
Ray Ward liked to use to reduce drag.
YMMV,
Mark Napier

> GB, what size Warp are you turning?
Hi James, I have a 68" 2 blade Warp Drive installed, originally I used the 3 balde
66" GSC prop that was on the 582 while I got it fine tuned it never produced
the TO and climb that I now get with the 2 blade Warp Drive. As posted guys
are now going with the AreoLux prop and are very pleased with it.
Hi Mark I installed the PVC strut streamlined covers a couple of years ago and
they do make a noticeable improvement in cruise.
Also as post Jerry at Greensky is a great guy and very knowledgeable on both engines
and is more than willing to provide with information etc.
