arlockstedt is on a distinguished road

just found this -
The Arrington 90mm drive-by-wire Throttle Body - 819cfm at Wide Open Throttle a full 178cfm over a stock 80mm throttle body..

stock = 641 / 1.5 = up to 427hp - 22% drive train loss = 333rwhp
90mm = 819 / 1.5 = up to 546hp - 22% drive train loss = 426rwhp

so an 85mm tb would be a great half way point and should make a difference if you have a bunch of bolt ons helping air in and air out.....
