on the street with pump gas and meth the truck seems to be happy around 15psi and 15deg of timing. any more than that and i see knock. put in strait 114octane and i was able to turn it up to about 19psi and 19deg of timing. on the dyno i went to 21deg of timing and it liked it but on the track it saw knock at this level. i think i am hurting the head gaskets and pushing water by trying to turn it up higher than this level and geting knock. i think with better fuel(c16?) i will be able to go higher on boost and timing and avoid the knock.
i swaped pump gas back in and turned the boost back down to 15psi then gave it a quick run at 19deg and sure enough it showed knock. 17deg and the same thing. 15deg and i got a clean run. it is nice to see some consistancy.
