Default max psi with just a front mount intercooler...

no meth or alky..just the intercooler on 93 octane. i know it will vary on compression, timing, weather and other variables. lets just say in the summer what kind of psi are you able to run just on 93 octane?

i did a search and didnt find to much.

I'm running 11 to 12 daily in my truck. Single 67mm, mid sized front mount. It was cool for the first time in a long while on the way to work monday morning. saw 14 to 15 on a few blasts, leaned out a bit as i'm taxing the fuel delivery with that much air, but still quite happy with it being 11.7:1 or so.

Still enough for the grin factor on the 4-2 kickdown shift, some tail wagging at 55 on 295's out back is just about right

93 pump fuel, not other injection (yet )

about 9:1, old pistons from the car (setup for 8.7:1 with a 72cc head). But I've got stock casting 5.3's on the truck. So it might be a hair over 9:1, never sat down and figured it out.
