Hey guys, was doing a bit of research on the MREV2 and it seems most of you see little to no benefit in throwing it on an automatic powerplant. $500 isn't really on the cheap side, and I was wondering if the $450 I paid for HFC would really out-do an MREV2 in terms of bang for the buck in the long run.

Current mods:
-5/16" plenum spacer
-DC headers
-Stillen Gen 2 catback
-Stillen intake / Z-tube
-Osiris tuned

The Berk HFCs will go on the car next month, same time as I will have the Hotchkis sway bars installed. Planning a final tune near mid summer timeframe.

WIth an MREV2 installed afterwards, would the small hike in mid range TQ even be noticeable @ WOT?

Thanks for the input, much appreciated.

 

Installing a Motordyne MREV2 on an AT isn't worth the cost, you might get max 2 whp. Once you've installed your HFCs with all your other breather mods you're going to need a retune. There's a big difference between OE cats and HFCs which should net you more whp.

Thanks for the $500-saving advice, I'm pretty excited about the HFCs... I guess there will also be a bit of a sound increase in the engine braking melody heard over slow drive-by's where I'm hitting 3-2-1 in manual mode hehe.

Unless somebody has a case to make on the MREV2 being a + for 5AT cars, that nails it.

On to my evaluation of everything involved with a potential drop, should I eventually change my mind.

 

Since the MREV2 is basically an AT lower plenium it's a total waste of money. Find another plenium and lower intake and port them, there is some power to be found down there. Look at this thread. and search the Intake/Exhaust forum

Even Tony at Motordyne has said that the MREV2 doesn't do much on a non-revup motor.
