My EFR 8474 Black, made 800awhp on a roller dyno. at 25-26psi. E85. Shaft speed was around 106,000rpm 1.01 rear. The rear is maxed. 6 boost Turbosmart 60mm gate 3.5inch exhaust Head is worked to the shithouse. Bain racing. VCam. 272 exhaust. RB28 - RB26 foundation. You have an intake issue. Start getting proper data and I mean go back to the simple things. - Pressure test your intake - Block off the Turbo BOV, you don't need it. - Test pressure before and after your intercooler If your head is pretty stock, that is your issue. Especially if it is NA. Take it off and spend $10k on it. -
Temp = -21.052 X Voltage + 114 That should get you pretty close. Calcs based on two points I could do easy calcs on (30 and 70 degrees). It also says your sensor should only read as low as 9 degrees when it maxes out at 5V, and should hit a peak of 114 degrees at 0V... Just as a heads up if you were going really cold places, or wanting to be aware when temps really go up with it. -

You're not wrong but 5W30 at 100C is like 10 cSt vs 25 cSt for 10W60. If we think in terms of viscosity margin 10W60 will probably still be ok at 130C but 5W30 is probably too little. It's absolutely shocking how hot the oil gets in something like a stock FL5 from only ~3 minutes of use on the Nordschleife. I would not risk taking a car like that to anything remotely intense without a ton of work done for cooling. Heat shielding on the manifold/turbo/downpipe, oil coolers, etc.
