1:41.169 - $19,950 in mods, I went with my previous theory of more tire is more better, it seemed to pan out. I may have been able to squeeze more out but I hate understeer and insomnia has kept me up late enough 
I got some time when i learned short shifting by 500rpm gave me lots more acceleration, also that corkscrew is a tricky corner, and i found i didn't have to brake as much as i thought for the corner before it.
