I am curious if anyone has tried switching the upper manifold to the revup manifold to see the difference. maybe in an F/I application, you could pick up big gains. maybe?!?!

 

With the Revup plenum being larger than the standard lower plenum I figured under boost it would flow more. When I swapped mine out and did dyno testing my car didnt make any power. Almost tuned completely I was going from 400whp to high 370's, and I lost low end TQ, AND my TQ fell off MUCH harder up top. I would hit 300ft/lbs @ 3000rpm's with the Revup Id hit 300ft/lbs @ 3600rpm's. On my car, and I believe Cheston with the PE TT also tested it and found it not to work.

 

thanks alberto.

I have a revup with the motordyne mrev2 on it. when I put the turbo on, I wasn't sure if I should stay with the mrev2 or go back to the stock revup plenum.

I was curious to see if the revup plenum worked well on the standard engines when under boost. if so, that would've made the decision easier......

 

No problem-you would think the Revup would work better but it wasnt the case on my car. NA Revups gain great midrange power with standard lower plenums and a spacer compared to their stock plenums + spacer. Seems to be the case with standards trying their plenums. I have only heard of a few people, and they seemed to be NA who have liked the revup plenum on the standard motor. If I were you Id stay with the MREV2. Buddy of mine has a Revup TN Z, who runs MREV2 also, he will be dynoing this Thursday so Im really gonna pay close attention to his powerband compared to mine.

 

oh cool! please post his results when you find out!

thanks,

Andrew
