How would you get the heat out of your Supra?

Read up on fluid dynamics. Toyota did a lot of expensive research to make sure that air going into the front of the car is directed through the radiator, but when you change things around (remove stock fan or shroud, change the front bumper, remove the engine undercover) you negate that original design and scratch your head when your temperatures are going higher than they should.
I'm not saying all aftermarket parts are bad, obviously a larger aluminum radiator in place of the stock one will lower temps, but removing the shroud or undercover will have more consequences.

My vented hood, CSF radiator, and bomex bumper dropped my oil temps 30 degrees, witha 13x6x2 oil cooler it dropped the temps 50 degrees while driving. While driving my oil temps now never go over 140 degrees and in traffic while stopped rarely moves above 185-190 where as before the mods while stopped in traffic it would go as high as 220 degrees. The vented hood and big mouth bumper made the huge difference in temps period.

I thought good operating temp for oil was 80 - 90*c (176 - 194*f) 140*f is 60*c which to me is a bit on the cold side. I was always of the opinion oil and coolant should run at the same temp (or there abouts)

I think you are correct. Cars that don't reach operating temperature generally aren't as efficient as they should be. That's why you have a thermostat to help your car reach operating temperature more quickly.
Oil temp of 140 is indeed bad news. His saving grace is that it gets higher at other times. Water is one of the two main byproducts of combustion and the oil must reach at least 180 in order to get rid of it or sulphuric acid forms. It's why short trips on an otherwise normal oil system are considered severe service that require more frequent oil changes. Lets hope he's either doing that or using an oil with a good TBN.
+another for ceramic coat.
My header is ceramic coated and only takes 10 minutes or so to cool off to where I can touch it. My uncoated Pacesetter header you couldn't touch for HOURS.

Is Mathlock On?
Coatings FTW!

Go to that site and you can do them yourself!
It sucks that my new rad can't take a shroud.
QWIKSTRIKE;1060688 said:Great answer.....ask me how I know
Do you get water in that hood?
Noticed the same thing, by the time I can touch the header there's no way known I can touch the cam cover it's so hot by comparison!Tanya;1061346 said:

Is that a show with an old guy and a calculator that solves crime? :icon_razz

A bud here has a mint 87t that's virgin, I was shocked at just how much effort Toyota went to sealing up the front plastics, most cars are missing much of the foam seals.

My Supra runs better when cold but at operateing temp its not as strong any ideas?
just chimeing in....i have a NA down here in florida. ceramic coated headers and intake. underhood liner gone, from falling apart over the years of abuse by previous owner. i went to Thermotec.com. they have some pretty good products. dealer hood liner-$350. roll of thermotec liner material--$50. hope that helps. good luck.
