Posted: Tue Feb 05, 2008 2:11 pm Post subject: Oil cooler mount / wedge |
|
|
I'm working on my plenum/baffling. I'm starting with Vans baffle kit. I have decided that I would like to mount the oil cooler off the back of the #3 cyl back plate instead of the firewall.
I'm also using a Sam James plenum - I'll be contacting them too!
How have others done it? I'll even look at firewall mounts - to see if there are any good ones
Anyone have plans for the wedge option that I have seen (somewhere)?
Thanks,
Ralph

Robby Attaway http://www.attawayair.com/index.html had a mount that
would attach to the aft baffle, don't know if it will work with the SJ
plenum, as the plenum is placed pretty low wrt to the baffle. It's not
listed on his site, but If you call him he will let you know about it.

Is the Sam James plenum working out as promised? Anyone out there flying with one that has an opinion? Wondering if it is worth retrofitting into a Van's RV-7 cowl.

I haven't had a chance to contact Robby yet and I haven't had any other responses about a wedge mount.
From the SamJamesd instructions show - it looks like the wedge in their photo is in a RV-4 so it may not work with my 6A - even with their plenum.
I'll let you know what happens as I need to do something!

I have the Sam James plenum and cowls on my RV7A..........since new. While I can't give any before and after performance figures I don't think I'm getting any better performance than those with "stock" equipment. Overheating has never been a problem under any conditions, even on hot Florida summer days. My CHT's however are quite uneven with the #4 cylinder running up to 100 degrees cooler than cylinders 1,2 &3. As to speed, I was led to believe I'd pick up 10 to 15 MPH over stock, but I don't think that's happening. At 8,000 ft, 2,700 RPM I see about 195-200 MPH ground speed on a no-wind day. I have an Aerosport IO360 and a Catto fixed pitch prop.

Garry, That speed seems in line with stock. Sure would be a lot of work to change over to SJ plenum & cowl for me at this point. What MP are you getting (at) 8K' and 2700 rpm?
