As far as the fuel systems limits i thought it was determined that both the injectors and fuel pump were more than suffecient for turning up the boost near the s/c's max. I thought it was the tuning that was necessary at that point in time to eliminate detonation...? Maybe i need to re-search.

Yeah, it turns out his problems at WOT were due to the fact he had headers installed. When I read the thread, the headers were still being fabbed. I missed his post were he stated they got installed. He made a post in a different thread (the LET headers thread) stating he had no problems with the 192mm pulley UNTIL he installed the headers. Here is that post: https://www.crossfireforum.org/forum...9&postcount=69

So that means we don't yet know what ratio will give us fuel problems at WOT WITHOUT headers. It could still be possible to combine the S/C pulley with an aftermarket crank pulley after all. Hopefully Code3 will do just that and post info.

As to the 192mm running the S/C at near max, someone posted that, but didn't show their calculation. They just stated a number. I wish more people on here would show their calculations, so that others could verify the numbers.

I'll try to actually measure my S/C pulley today, so we can be sure of the size. My calculations above are based on the size Brian stated. I don't think he's lying, he just never said were he got that info. And I haven't had the chance to do more research to verify.
