IIRC under a load my 83 was seeing over 10 psi at 2000ish rpm. Coupled with the tubo I am wiling to bet I could get over 15.
Now to just find the time .........

10psi@2000 rpm is Awsome ...I only realistically expect to see my turbo make boost 500rpm sooner than the next guy running a gt35 with 1.0 ar.
But with Sids results say to me that 10 or 11:1 seems like the ideal compression for a E85 turbo engine ..and if it makes fat mid rage great ..
so when is the 83 seeing full boost of how much ?

Adam, I was running ~18 psi and it was pretty quick. I'm pretty sure it was below 3k rpm. This was with a very small pulley. In hindsight I wish I would have stuck to modding that car instead of futzing with these others, but........
here is a little junk video of a takeoff http://www.youtube.com/watch?v=gvYzR0AhyWk

yeh that video is junk small pully ??? super charged?
but yeh it looks like it has 12 psi as soon as it sees any load at all and i would imagine in on off driving there would be 12psi or more at 2500rpm. did you get more timing into it ??
you know how sometimes you can retard it heaps the boost gauge goes twang but the car is not ultra rapid but you say it was nice and fast ...mmmm

ADam had lots of timing ~ 30 degrees at that point IIRC. It is supercharged
I barely played with that car, and the 60' time was 2.07 which rivals some of the fastest 951's. It certainly has bested my best 951 launch.......by some margin too.
I can't wait to combine the takeoff of that car coupled with the top end of my others.
