90mm vs 102mm Throttle Body on LSA

Have any of you performed a back to back 90mm vs 109mm throttle body comparison on a ZL1? Would be interested to know the results. Thanks!

Thanks guys I am porting the supercharger and was wondering had anyone with head work, cam, headers, upgraded fuel pump had tried a back to back comparison between the two TB's. I purchased a new supercharger to have ported, I might have to just do a back to back between the two myself. I thank all of you guys for chiming in.

Depending on how fast you are spinning your blower and if you have upgraded the air intake pipe as well you could see 20 RWHP.
