Antonio, keep the EGTs under 1600F max (aluminum starts to melt just north of 1600F). Shoot for 1550F (or 850C) as a good target. As for oil pressure, not sure.

I do a lot of autoX and drag so i was thinking og trying t achieve around 1400 so I have a safety factor. What do you think? give me your thoughts to see if thats a good number or to low and I will need a more agressive number

I'm tuning my RS-T for 1500F in 4th gear at WOT. I see closer to 1400 in the lower gears. What injectors/fuel pump are you using? What duty cycle are you seeing on the E-Manage? What are your timing settings? Are you using both fuel maps (Air Flow Adjust and Additional Inj)?

I heard an SCCA rally driver say that "1600F is the magic number..." and "use your EGT gauge as a tach" but I don't like being that much on the edge. I know in a turbo application a good "street tune" will have EGTs quickly jump to 850C and then slowly drop toward 700C-750C at WOT. With your CR you should try for something similar. Remember, det=bad and timing=power... that should help you tune
