And I'm feeling pretty smug about it.

Any specific reason? I would assume that you monitor oil temps correct? I really like your car, don't let her get hurt.
:suspect:
Saaawha, you crazy fool! You must trust your tuner skillz :)
Why would you want to make sure that your oil is hotter than normal?
Hmm, guess you dont care about longevity of your engine.
It's has nothing to do with longevity. The pickup is still a straw, the oil cooler holds... an extra quart? You think that helps the bearings? You can buy oil for your operating temp range just like you can buy brake pads for your temp range. Besides, He's controlling the load on the engine with the tune and can cap the ceiling. Must have a ton of data being collected on the engine to feel comfortable enough to do that.
What's your oil temp range at full load and at idle Intropy?
As long as everything is in good order, you wont have an issue. We do this on plenty of cars.
That being said, if you plan on auto crossing or road racing it would be a good thing to have im sure after all the continued high RPMs.

I essentially deleted mine in 2004 by gutting the oil cooler bypass valve. After examining the oil flow diagram I replaced the valve. My engine bearings looked fine after limited mileage. It's not something I'd feel comfortable with on a daily driver in 100+ deg F weather or during continuous abuse. But that's based simply on my engine's oil pressure (20W-50 or 5W-50) and water temperature.
Where is this high temperature oil J. Fast?

I was having a hard time believing that my rusty old stock cooler, with no ducting (had to remove for the FMIC), and tilted at a 20-degree angle was doing much of anything anyway. I'm running 20w50 now that I deleted it.
Ahh so you're just guessing everything will be fine, that makes me feel better. :scared:Quote:

As a powertrain cooling expert:
Don't feel so smug.
Hmm, nope, still feeling pretty damn smug.
Got an oil cooler on that NA of yours? If I'm going to be dislodged from my happy place, someone has to convince me that my massive 5-second, 240whp-merge-into-freeway-traffic poses some dramatic thermal threat to my engine.
just monitor your oil temps. for example, the maximum oil temp spec for a lamborghini V12 is 135 degrees celsius.
Yeah, for a DD without any extended high RPM runs I don't see it being an issue. If you ran a few laps on a roadcourse you'd probably be buying a new engine though. :p

Yeah, both cars are with me in LA. The TD05 car is so freaking nice I don't even care about this one anymore. I tried to sell it for $3k (figuring I'd get a lowball $2500) and couldn't even get rid of it. :lo5l:Quote:

Yeah I don't expect any problems considering I really only commute in it. Honestly I will probably replace it with a front-mounted aftermarket one, I just needed to fix the leak and thought I'd stir up some shit in the meantime.
Fuck no! your shit is toast nOOb!Quote:

Got turbos heating that oil on yours?Quote:

Worst argument ever. They give that title to literally ANYONE these days.Quote:

well, the FD rx7 comes equipped with 2 oil coolers, one under each headlight. and a single turbo intercooler that is about the size of one of our OEM sidemounts. its all about knock control. the heat of the motor has a lot to do with it. you could tune out the heat with some timing adjustments; but since its just a temporary fix and not something planned for high performance use ("i deleted my oil cooler because it wasnt doing anything anyway!" <- bad idea) i dont see it being a problem.
Interesting observation.Quote:

"Well, the 6G72TT was estimated/tested to produce 460,000 BTU/hr at full load into the cooling system and 238,000BTU/hr into the oil cooling system based on it's available fuel rate and BSFC under full load. The stock cooling system in good condition was designed to expel that with a safety factor of 1.8 to account for eventual cooling system deterioration. Removing the oil cooling system will make the water cooling system pass it's safety factor trying to expel the additional heat under full load or additional load from modifications, which will cause oil to overheat and eventually the whole engine to overheat. OEM applications usually call for a oil cooler of xBTU/hr per 100HP produced at the flywheel, even for 'daily driving' conditions."
The ability to use your current knowledge or ability to gain that knowledge through research, process it, and then release that knowledge for the benefit of others through clear communication is the hallmark of an excellent engineer. Those type of people, whether or not engineers or just people who push their own cars to their own limits, are usually the people who a community such as ours look up to for advice or to admire their accomplishments. Adam as achieved such a position through his accomplishments and such sharing of knowledge.
Strange, you can find nearly all those people in one place...Yes I pulled those numbers out of my ass.
Not as much as engineers but yeah nuclear still sounds cool :suspect:Quote:

I'll stick with my oil cooler. It surely can only help and surely can't hurt.
