Heavy Z Posted January 16, 2006 Share Posted January 16, 2006 Hello everyone, it looks like Holley just released a new TB that will fit on the stock LS intake manifold. Any word on the street about it? I was thinking about this for my FD LS1 and wanted to get some feedback first if I can. I it too soon to tell or has anyone seen these or read any tests? Thanks! http://www.holley.com/HolleyNews/article.asp?ID=62 Quote Link to comment Share on other sites More sharing options...
Phantom Posted January 17, 2006 Share Posted January 17, 2006 I've seen a couple tests on different throttle bodies on the LS1 engine. So far they have indicated that all the 90mm TB's are pretty much equivalent . You might find one that will give and additioanl 3-5 HP at 7,000 RPM but below 6,000 doesn't seem to help. Bang for the buck seems to be the LS6 intake manifold & GM 90mm TB. Quote Link to comment Share on other sites More sharing options...
DaleMX Posted January 18, 2006 Share Posted January 18, 2006 Also the bolt pattern on the Holley is a 3 bolt. The FAST intake is a 5 bolt so it might not be compatable is you plan to upgrade. Quote Link to comment Share on other sites More sharing options...
