How Hot / How Thin Should Oil Get And Issue With Brakes?

[stÖrmy]

Hi guys I just got my rb25 s13 back from the tuners and thought IDE give it a bit of a test run...

Car info :

made 350rwhp

High mounted kinugawa OIL Cooled only

FMIC mounted with ports at the top

Have an oil cooler and relocation block

Forward facing plenum

Was running cheap penrite 20$ oil

Ok so after letting it idle for a few minutes I went out or a quick drive, then came in and did a few donuts, snapped 2nd gear and done another few donuts, all up it was about 3 or 4 minutes worth of driving, after bringing it

Back in the shop I noticed a oil leak so put it on the hoist and had a look under, my sump plug was hand tight and had no copper washer..... I think I forgot to put on one... What a tool! Anyway I took this opportunity to drop the cheap oil and throw in my penrite racing ten tenths oil, pulled off the sump plug and the oil started rushing out really really fast , it was almost like water and was extremely thin and black, keeping in mind the oil was brand new before Going To the tuners.

In that few of driving and the few hours at the tuners could the oil have gotten so hot that it went black and burnt already ?

After it was done draining I put a new sump plug with a copper washer and lowered the car to put my new oil in, at this point I noticed that my rocker covers and intake plenum were boiling hot, way to hot to touch for more than a few seconds...My oil filter was also boiling hot and the oil cooler was a bit warm, the intercooler was a bit warm.

Is this all normal ? Could having an oil only cooled turbo be contributing ? Or am I just being paranoid ?

Also completely unrelated I noticed that my front wheels do not spin freely , I'm pretty sure they are meant to ? Could my front

Brakes be rooted ?

Just checked again to see if it's cooled down , it's still freakin hot... My turbos exhaust housing is cooler than my rocker covers right now

Its called heat soak, any car when switched off has the hot water rise to the top and get things very hot with the engine off, more so than when running.

Your oil being black is not "burnt", its just full of contaninates, im surprised you threw it on a dyno, did burnouts etc with a cheap oil and then thought about using the good oil.

Generaly speaking you want water and oil temps to ideally be around the same temp.

Ok cool thanks for the reply man

Well yeah ive always used what ever is on special in terms of oils, my last drift car only ever got the helix 18$ on special stuff and ran fine every day even with drift abuse.

Either way i guess i was just being paranoid
