a/r and turbo question..

[boostcono]

Hey larry how much diff. in spooling and top end those the a/r affect...?

My question how much diff. in spool and power is for example..

SP58 with .58a/r & .81 a/r...
SP63 with .58a/r & .81 a/r...

Im trying to figure out how much diff. is there between a small turbo with the big a/r and the larger turbo with the smallest a/r...

The 58 with .58 would attain full boost in the 3500-3800 range and top out in the high 500RWHP range, although in some rare freak instances we have barely cracked 600!!

The 63 with .81 would attain full boost at 42-4400 and top out at a tick under 700.

Interesting.... so would say that a SP63 with .58 could get full boost at around 3700-4000... and maybe top out in the 590-630rwhp..?

And how much power could a SP63 with .58 put out at around 18psi..?
