solutions for oil temp on track

[tomfree]

Jumping in to the "d@mn this car runs hot" thread after this weekend. A buddy and I shared the car this weekend at Carolina Motorsports Park, and I got the "I'm too hot" message on screen, and it absolutely pulled fuel/timing a couple of times and just felt like the car was hitting a brick wall. Ambient temps were high 70s to mid 80s all weekend. We hit the fuel cut situation on the 3rd session in a 2 hr window and spent the rest of the weekend working around it. My car is 100% bone stock power, no cooling aids. I want to be able to return the car to as close to bone stock as possible, so I'm looking for a used hood to cut up for venting. I'll have to search around here for other stock power level cooling suggestions.

Intake manifold is the one thing that will make a noticeable difference.

You could instead spray meth for a cheaper route but pros/cons to that.

Verus is supposed to have a oil cooler coming out very soon but I'm pretty sure your issue is IAT.

I'm inclined to agree with you on the IAT being obscenely hot. I've scanned some of your "look how much the Wagner IM drops IATs" posts in this thread.

I'm at this precipice I've reached on numerous other cars in the past - the list of stuff that I need/want for the car is piling up too quickly. It is a patience/funding tug of war now.

I took some of razorlab’s advice. I put in a pure850 doing about 23psi of boost as the stock turbo was outside of its efficiency range w/ e50. The charge air temps before the manifold are definitely lower vs stock turbo, and the Wagner seems to be a little less stressed trying to cool it down. I have a track day at chuckawalla in a month so im curious how IATs will be.

So what happened? Did the new turbo improve your temps at the next track day? So a conservative tune on an upgraded hybrid turbo will generate less heat than a tuned stock turbo for lower IATs, charge temps, etc.?

Also interested, since this is what i am pondering right now, moving to a bigger turbo setup with lower boost....

Specifically, with IAT's, yes the turbo helped pretty significantly. I have both a track map (boost limited up to ~20PSI depending on E content) and a kill map. Track map has similar boost to the BM3 OTS flex tune I was using (~22lbs) and I never run into IAT issues unless it's 85F+.

Most of the time I don't run full sessions and just run my kill map though. If ambient is above 80F, I pull some timing after a few laps. I've been looking to hood venting and/or water injection to help with this further.
