what is the difference physically between these two intakes. I am not talking about how to tell them apart by looking. I want to compare the dimensions

Throttle body size
Plenum volume
runner volume
runner length
what the different flow numbers are.

thanks

throttle body size is the same for both intakes.. not sure bout the others though so i'll let the experts tell you bout those..

tb is the same, runners are the same, but the mass inside the intake is larger. meaning more air. if you look at a pic of both of their bottoms then you'll understand.

Throttle body size - same
Plenum volume - larger
runner volume - same
runner length - same

doesnt sound like it would make much of a power difference, but trust me, there is

also different casting pattern to the ribs on the bottom

the obvious differences are lower floor section and no EGR provision on the LS6

this is what I found
_______________ls1_____ls6
Plenum volume - 5.06L--5.19L
runner volume --.536L--.541L
runner length ---262mm-262mm

I am not sure of the TB opening, so if anyone has a LS6 lying around and would like to measure it that would be great. I have a LS1 and i will try to do that tonight.

pretty sure the TB size is the same

A ls6 good for about 10-15rwhp over a ls1 at 5-6K rpm's.

what about the throttle body it self..any difference between the ls1 and ls6?

nemss1

exact same

I think there was a post a short while ago about how the LS6 doesn't leak as much as the LS1 but that may have been an LS6 to LS2 comparison...

i have a 1998 camaro z28 auto stock form for now but have a chance to pick one up for pretty cheap i am saving money for the texas speed 2.5 head and cam kit and some other mods but how far can you really go with an ls6 intake is my question
