turboII guys, a couple boost/speed questions.

turboII guys: how fast are you at 10psi?

i upgraded my fuel and i was thinking about richening up my SAFC (i'll also be borrowing my friends wideban for a couple weeks) and running 12 lbs on stock turbo/intercooler...

i am going to the dyno soon and just wanting some kind of estimate so i can have a goal for the dyno day. also i'll be going to the track as soon as it opens and i'd like to know how fast you other turboII guys are so i can know what to expect. (the track is 1/8th mile btw)

at 10 pounds I'd guess around 225 rwhp, 12 pounds maybe 240ish if you can do a quick pull before heat soak sets in to the IC. I'm willing to bet at 10 pounds you'd actually lean it out with the safc a tiny bit.

edit: these are the max numbers I'd expect if you're shooting for a great dyno

what should i be expecting to run in the 1/8th mile at the track?
also: i'm just playing it safe with the SAFC right now to make sure the AFR's are nice and low til i get the wideband hooked up so i can actually safc tune.

what was your trap on that 12 second run?

1/8 mile times can vary too much due to traction, but somewhere around 9.0@ over 81 is a 13 second run
