--> RV8-List message posted by: "Dan Beadle" <Dan.Beadle@hq.InclineSoftworks.com>
I am building an RV8 for use up in the mountains. Normally I would
turbocharge but that is not a simple option for the RV. So we have
decided to put in a larger engine and "de-rate" it for SL to 200 HP,
giving us a little more performance to cross the mountains at 16,000'.
=20
We have also decided to go light up front wherever possible to offset
the weight and moment of the bigger engine. These include:
=20
- Grove Landing gear (-18#, maybe some speed gain)
- Aerocomposite CS prop (-30#)
- James Cowl and Plenum (no change, but 10-15K speed gain)
- James Wheel Pants
- Rear battery
=20
Does anyone know the best way to order the finishing kit and avoid extra
parts from Vans? Do you have any recommendations for changes?

Hi Dan,
IMHO, you'll need to add dual electronic ignition in place of the Mag's.
One of the Lycoming engineers told me that the 360 engine with a light
propeller brings the accessory case gear harmonics below the 2700 RPM level.
It
doesn't damage the gears, but the Mag's and fuel pump don't last very long in
this environment. This could apply equally to the 390 engine with the light
propeller.
Regards,
Jim Ayers

I've got an article describing what you can leave out with
the Grove gear here:
http://www.rv8.ch/article.php?story=20040404153921362
While it won't save weight, you may want to ask Grove
about the single piece gear they offer for the RV8, but
didn't have on their website last time I checked.

Hi Dan,
I don't have a recommendation.
I'm a distributor for the ElecrtoAire. Also, Lightspeeed is a local company
that I like. But I'm really interested in the development of the P-Mag.
The ElectroAire and the Lightspeed electronic ignition systems both need
extra care with the electrical system. So no single point failure causes the
loose of all electrical power (and the engine noise).
The P-mag (available for 4 cylinder, but not 6 cyl. yet) is independent of
the electrical system above 900 RPM. They seem to be getting past the
problems that are typical in the early production phase of a product. One of
the
local pilots has an E-mag and a P-mag on his Lancair. I'm watching for his
success.
Regards,
Jim Ayers
