90mm I know that most of the blown factory motors use large throttle bodys but naturally asperated 90mm , Sounds like when I was younger and got alot of 600cfm carbs for cheap because every guy with a 327 thought they needed a 850 double pumper to go fast. I got a small block tunnel ram with two 1150 dominators and nos fogger . :D :D :D
I read it in a couple of non-GM announcements, but I'm still skeptical of a 90mm on a 400 hp 6.0. That's 44% more flow area than the current LS1/LS6 TB. Now that sounds about right for the reported 500 hp Z06 car for 2006.
Once or twice in the past media folks have misprinted specs and they have become "common knowledge". Count me as a skeptic so far.
stop strokin' it's a reality. The 90 MM throttlebody was part of the Detroit presentation concerning the C6. You can view and HEAR the comments on the webcast simply by going the Chevrolet website and working to the Corvette links, and/or going to the C6 section on this forum and follow the threads referencing the webcast
