Gen1 Question:
The airbox mod, has this ever been proven not to work on a dyno?

I really wonder about the upper limits over 140MPH in the Maxton Mile......

Down low at the Quarter also would be nice to see before and after the mod?

Yes it has been proven to work many years ago.

If some has an 07 switching to this mod and we do it. I will post before after numbers.
