Hello brain trust,

I am upgrading my engine to the IO375, and will need a 13 row oil cooler. Looking at getting the showplanes set up, however concerned about the fit with the EFII system 32 fuel rail. Does anyone have this set-up and know if there will be a problem with #3 injector and clearance with the cooler & oil lines? Or should I be shopping for the RV10 set-up with the 4" tube? Or other options I am not considering?

Thanks

This is what I have on my 8A and I really like it. I don't know why people still do it any other way - seems either more complex or too difficult to vibration isolate.

I run an 11 row HE cooler, firewall mounted no problems in TX.

Do you have a picture that I can check out? thanks.

Not a great one with a wider angle view but this is what I have:

This is from my 14 but 10 is as you mentioned similar just mirror image. I've seen several Showplanes set-ups builder struggle with vibration and alignment issues.

The oil cooler manufacture recommended steel fittings and Vans supplies aluminum which were used initially. It's very difficult to get the 90 clocked tight and in the correct orientation so my top 90 weeped for many years. (I wrapped the fitting with a paper towel then wrapped that in gorilla tape and changed every 100 hours but looked stupid) Changed to steel and it seemed to have a greater radius for proper torque. Didn't leak after that but if I was to do it again would have used a hose with a built in 90 on that end which would have been plan B. one

I'm not sure where you are located but most people find one needs an oil damper in the North, but I find my oil damper in the south extremely useful for my parallel valve 540. It allows me to keep it closed and supply more air to help cool my CHT's. Even in the middle of summer in Florida, I can keep the flapper closed till I get up to 2,000 to 3,000 ft before my oil exceeds 190 F and then open the damper. Gain another 1,000 ft reduce throttle slightly and go LOP to cruise altitude. Never exceeds 380 F as long as it's the initial take-off of the day. An oil flapper is a waste of $$ on an angle valve engine with piston squirters even in the winter in Ohio for me at least.

I also have EFII and you will love it (Along with SDS if used). For EFII the fuel rail needs to be well thought out, and proper clearances must be adhered to. You don't want any rubbing or pulling up or down on your fittings. Proper slack and vibration reduction is key. The insulated fuel lines from Tom and Steve seem to give one the proper stiffness to help the issue.
