260 oil temp with 34 row cooler.... help!
 

I hit 260 plus today on track with the 34 row from z1. It was 90F outside in TX but i was hoping for something better. I am trying to figure out a fix before next summers track sessions. Hopefully next month we'll be in the 70s lol!

My ideas are running a second oil cooler or making some sort of air funnel for the radiator / oil cooler.

Has anyone attempted an air funnel or had bad experience with 2 oil coolers?

Thanks!

Try some Tracspec vents for the hood. They are your best beat.

Hard to tame 90F plus and high humidity.

Changing to a different weight oil and/or a higher volume pump may help.

thanks for the advise!

Maybe an oil pan spacer to further increase oil capacity, but that’s just delaying the heat buildup, not solving it.

Don’t think there is anything else that’s readily available.

i think its all prolonging the inevitable. especially in 90 plus heat (is it October??).

Talked to several people today who were in faster run groups with Zs and they all have the same issues. Have been wanting to avoid cutting holes in my hood to comply with SCCA TT but id rather not stress heat while having fun.

You can make some air guides behind the bumper to direct air into the oil cooler and radiator. If you do it right. You won't bleed air around the sides. All air would have to go through the cooler and radiator. The hood vents will really help out.

I ran that combination. It's about 8qts of oil.

May want to remove the thermostatic sandwich plate (if you have one), possibly not opening all the way up after it gets warm :ugh2:

Go BIG or Go HOME!

Have the Mine's or Varis style "bumper ducts" ever been proven to be effective or not effective?

get your cooler into free air and duct it. mine is in the passenger side vent here. I've run on 105 degree days with a 40 min session without breaking 230

Welcome to my world of issues!

I am trying a few things, 1st track spec hood vents, 2nd a 1" duct so air is more forced to go through the cooler rather then around, 3rd relocate it to the side with the stillen bumper.

Really don't want to buy a stillen bumper... think i'm gonna have to work on some guide to force air through the cooler / radiator vs spilling out the sides. probably do vents at some point too
