According to them.....quote"THIS PLENUM, USED ON A 14LB BOOSTED TRUCK MADE 3-5 H.P. AND AN AMAZING 12 FT.LBS.TQ. "

They do some awesome looking polishing....

 

You are correct the reason behind this question i just don;t like the looks of the new power plenum it will take me a while to get used to it. but i plan on sticking with a ported and inside polished and all burs removed form the factory plenum it is supposed to be as slick as my bald head on the inside

Well... Unfortunately the last time I hit the dyno, we only measured the left wheel, and it came out with an extra 2.5 HP and 6.5ft/lb torque.

I would think the same would apply to the right wheel.
