Does anyone have any power numbers on different intake manifolds? I currently have the stock ls6 intake manifold on my 01 z06 with cam/headers and was thinking about doing the fast 102 with the matching 102mm throttle body. Any thoughts on this? From what I have seen, the ls6 manifolds are pretty good themselves and its not worth the money to upgrade.

based on engine mods the ls6 intake flows pretty well for your setup. the FAST 102 would be great if you did a lot of drag racing as the motor would be up in the high RPM range ..

a FAST 92 would be great for DD and lowend power as the intake goes threw the RPM range ..

on a stock LS motor a FAST intake wouldn't be felt as far as power just better performance .. now you do a set of heads/cam/headers and intake mani then you would feel the power gain 100% ..

this is all based on the info that i have researched and based on my opinion .. other info is greatly appreciated...

An ls6 intake works really well for it's cost if upgrading from an ls1. Most people see around 10hp over the ls1. A fast will generally pickup another 10-15 rwhp over the ls6. Since you already have the ls6 you could always sell it for about 400-450 and that will help cover some of the cost of the Fast 92/ls2 throttle body combo.
