To Ed,

Thanks for the input on the cushions. Sounds like I should be good to go as-is. I'd add the 1/8" padding like you, but I don't have even 1/8" to spare. The left nostril on the James Cowl will also feed the throttle body, which I plan to mount on the front of the 'cigar box' plenum, facing forward.

If it is the one you used, I think I'll give it a shot as well.  I was either going to use this type or the stock oil cooler.


I like the install and I'm likely to borrow heavily on this design for my intercooler.  I've got to put the intercooler right where you've got yours, but there would likely be enough room up in front below the re-drive.

The right side will have the radiator and the intake will be through a NACA duct.

Please advise.

Thanks!
Bill

I've started design/fabrication/redesign of my oil cooler mount/diffuser. Just as I had a 'final' answer on the mount & was contemplating the diffuser, it occurred to me that I didn't have any shock mount provisions for the heat exchanger. For those who have been flying for a while, have any of you hard mounted the cooler to its support structure? As the photo shows, the primary mount is direct to the reduction drive plate. I would simply add the shock mounts, but if I use this particular cooler (a CX Racing 30 row unit like the one on Tracy's 20B), I won't have any room. I do have the option of buying a 25 row or using the 19 row I already have on hand, but I'd rather have a bit too much capacity & throttle the exit air than start with too little & have to rebuild everything.

Thanks,

Charlie
