Suprakeith Posted April 18, 2018 Share Posted April 18, 2018 Hi guys after some advice on oil cooler size please. I doing a forged na-t build with end goal of around 1000bhp and will be using supra on drag strip and few track days aswell. I currently got a racing lines thermostatic sandwich plate. I have done search but can’t really find out what size I will need. Any help will be greatly appreciated Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted April 18, 2018 Share Posted April 18, 2018 Biggest you can squeeze in there Id say. More importantly you want a drag car AND a track car? Very different machines Quote Link to comment Share on other sites More sharing options...

Very different machines That’s what I was thinking biggest is best. No not building her for track, she going to be fast road car that will go up drag strip and do few track days, my mates skylines oil always gets to hot after few good laps and he has to come in and let her cool, I don’t want that hassle with mine Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted April 19, 2018 Share Posted April 19, 2018 People like Paul Whiffin will be better able to advise, but good quality oil and a decent size, quality ducted cooler will be good. Ducting is the key not just slapped in a hole somewhere and hope for the best Quote Link to comment Share on other sites More sharing options...
bignum Posted April 19, 2018 Share Posted April 19, 2018 I`m running a 25 row on mine, was seeing 110 after 4 or 5 hard laps @Donington last night, which is ok when using a quality ester based oil, so i`d go 25 row or slightly bigger tbh.

jagman Posted April 19, 2018 Share Posted April 19, 2018 You can fan assist an oil cooler with a small fan , power ,rpm and time are the main factors in heating oil up , drag racing the time duration is small so a lesser effect than track racing , track use and or autobahn driving are the biggest oil heating issues - sump return of 100 degrees isthe target ,this is the coolest oil temp in the system ,all other oil temps are relative to this . the highest oil temp would be around the rings and way over the sump temp , so if your sump is say 120 and not 100 -the other temps are also plus 20 , the oil thins and film thickness reduces with temp - every oil has its limit Quote Link to comment Share on other sites More sharing options...
