If you use a full synthetic which is too thin I find my setup just breathed too much while racing. i see. so mineral oil always for e85 engines. u ran 10.4 @140mph...thats an easy 9 sec pass with that mph. ur cars got plenty left in her. well done Some original photos have not been recovered yet.

I use brad penn 20/50 partial synthetic the green oil

i use HPR5 and change it at every 1000kms. (directions from engine builder) I also run an RB25 oil pump.

I also use the Penrite 25-70. Its a mineral oil. If you read the back of the bottle its the only one I found besides the big dollar race stuff that is E85 compatible. I change oil every 4 tanks of fuel so around 800-1000kms max

Cheers man, should have a 9.6-9.7 in it with my new convertor (turns out the one that was in it was in several pieces on the inside) I normally leave on around 15 psi but have let it go at 20 psi a few times. Standard rear end is still alive after around 25-30 passes =)
