I was wondering if anyone had the Trickflow plenum and what they thought of it? Also, if anyone knows what their dyno numbers/track numbers improved to afterwards.
For the price you can't beat it. Sure the Accufab looks good but costs twice as much. As far as gains I don't know but it has to help. I dyno'd my PI intake swapped NPI GT at 213.6HP. By comparison a 97 dyno'd at the same time with close to the same mods except the TB, Plenum and intake and put down 193...Just a guess but the Plenum TB was probably good for about 5-7 HP.
My numbers were before my cams in case you read my mods in the garage.
I had 03gt with a CnL plenum and bbk tb and it made a big difference in sound and power, you could tell it was getting more air, didnt have dyno #s but ran a 13.4 with it.OF course i had gears and just about every bolt on you could get.
