Exactly, but you cant just assume that they are going to be running something like agreddy kit. Do you know how many "budget minded" set-up there are out there running large turbo's? Maybe it's just the latest craze or something but there are several (that I know of) sohc's running larger t3t4's 50 trims even 57 trims with .48 a/r's or even .63 a/r's some even larger and yes they are tuned properly and street cars. Stock engines making 230 - 240whp on 10psi. it's insane. Tell someone like that to run 12-14psi their motor will be toast. 230whp is already pusing it for a stock single cam.
