Hey the weather's nice at least!

Anyways, I hope to be an owner of the JRSC one day. I think Mike (or someone from CSG) quoted me the labor cost to install it via Facebook this weekend, so once I get my cosmetic mods done I need to save up for it.

To anyone who doesn't have the oil cooler yet still tracks / autocrosses it, is it viable with the CARB tune to do so?

I don't mind getting the oil cooler if it's a good idea to keep things more stable, but in all honesty I'll probably be able to fully track this once or twice a year, if at all.

It'll mostly be used for day trips and back road driving, so if I don't need the oil cooler for that it'll help me save a bit of money.

Oil cooler is mandatory for NA cars that track. It is double mandatory for FI cars that track. Do not skimp on the oil cooler.

That settles that then! Might as well get it all done in one go.

Moto mike told me the following, if your going to track the car you need an oil cooler. However, if you plan on doing nothing more than the occasional spirited go then its over kill. He said " I would love to sell you something more but you don't need it" based on at least my needs. But yea if you track the car your going to keeping the rpms way up there and with FI its gonna get hot fast. But a few hard pulls riding it is not necessary

And yes, we've been cited for modifications (and passed with flying colors) with the supercharger. The LEO can choose to still cite you to go to the ref, but if you're legal, you just pay your $8.75 and go your merry way.

Really now? I'm super interested to see how you do this. Because that's exactly what I'm wanting.

I'd love to see quantifiable evidence backing up this statement. I have no doubt it's helpful, but after 12 track days without one and a well-running engine, I disagree.

I am completely in agreement with sw20kosh on this one. My buddy was running over 280F in his car (NA, not FI). He pushes his car, and is pretty quick on the track. I too was hitting close to that, before I went FI and added an oil cooler. If you're not hitting those high oil temps, my guess is you're not pushing it as hard as others.

There's no way I'd track without an oil cooler.

By this logic, if you drove for 12 days piss drunk and didn't kill/hurt anyone or get caught, you would deduce that driving drunk is safe.

Quantifiable evidence: 280+ oil temps at the track

Have you seen what kind of oil pressure you get at those temps? Probably not because if you did, you would freak out and buy an oil cooler.

Qualitative evidence: Everyone who tracks an 86 regularly has an oil cooler.

In the end it is up to you to decide. It is your car.

This guy did a test. Even thought it is with a supercharger and an oil cooler attached, you can see how oil pressure drops with oil temps. He didn't even get close to 280 F before he had to abort the experiment...

@CSG Mike @mkivsoopra @RehabJeff86 @BRZChix

Agreed. We have seen 275F+ oil temps in bone stock NA cars at the track in the middle of California winters (~45F ambient). You're either not driving hard or not watching your oil temps. You can do what you want with your car, but please don't suggest/imply to others that it is safe to track these cars without an oil cooler.

Someone wants to learn the hard way or just not pushing the car at all ....

Noon question here. How can one dial back the boost on a sc like the jackson to no greater than, say 7 psi at max output? I know turbos an do that with a wastegate and im interested in doing so for the safety and longevity of my engine

Have a larger pulley made.

Or install a wastegate into your intercooler piping that will bleed off pressure when boost reaches 7 psi. This will add complexity and be rather costly.

Boost is not directly correlated with engine longevity. There are other factors like ignition timing and cam angles and fuel quality. If you can't dial down the boost easily you can change these variables. Running the carb tune and/or running higher octane is probably the safest bet.
