I have done some searching but can't find what I am looking for, so I thought I would just ask:

Does anyone have any definitive data for the Grouppe M style intake and ROW air box's? I saw a few folks mention that the Grouppe M was good for +1 mph in trap speed in the 1/4 mile, but no other data.

As it's airflow dependent looking for data like 1/4 trap speeds, 60-130 times, etc.

I found some great data on the Renntech air boxes, but a little more than I want to spend.

Any info would be appreciated.

Always wondered haven't made their own intakes here.

From the GruppeM website for power gains. I can't remember seeing any independent ones on the board.

Thanks for the graph. About what I expect, but always looking for 3rd party validation.

Guess I need to invest in an intake and VBox and see what happens.

Where did the cone filters terminate to?

If you can wait about three weeks the new ram air hood will be available. It will come with new larger air filters/boxes and the hood in FRP material which will be a weight savings over the stock hood. Its a proven system that gained power just sitting on the dyno and improved 60' and 1/4 mile times. All for a price less than the competitions intake systems.
