If you have the REVUP, use the spacer with it too.

I am a little confused, thought MREV2 cam with a spacer just like my MREV did, correct? do you mean MREV2 is just the lower plenum?

no its just the lower plenum, you buy the spacer separate.

Hydrazine

That was the case. But the MREV2 has been modified to the point that it makes gains on the 287 engine all by itself, and many people wanted the lower plenum just by itself.

Some even wanted it so they could use it with their other aftermarket plenums or spacers.

So the parts were separated to make it so people wouldn't have to be stuck with buying both when they only needed or wanted one.

right. As Tony mentioned, the improved MREV2 can be used alone on the non-"revup" engines and experience gains also, and even moreso when combined with a spacer kit.

I have an 05 Track REVUP and was wondering if a 15/16" spacer, MREV2, and an APS Tallboy be a good combo? Or would the spacer and MREV2 be ok? I know the spacer and MREV2 are very good, but I was wondering if the tallboy would be a good addition to the two? Anyone have any personal experiences with this combo?

Turboimpreza07 - The MREV2 and 5/16" spacer kit will be a great performance mod for you car. Not having the pleasure of seeing an APS Tallboy plenum in person, I cannot say that there won't be issues using that along with the spacer kit. The APS plenum is likely accounting for the job that the spacer kit is doing, so putting that on along with a spacer would cause fitment issues under the front strut brace and possibly when closing the hood. HTH...

Does anyone think that doing the APS plenum along with the Mrev2 will yeild more power then the Mrev2 and the 5/16? Or are they about the same in gains?

Hydrazine

Undrgnd is using that exact same setup on his Z.

My guess is it will provide the same performance as a 1/2" spacer on the MREV2.

A little more high RPM HP with a little less area under the rest of the curve.

im sorry...im still really confused...awhile ago while i was reading the forums....everyone said that on a 287hp (non rev-up) motor...the spacer was the best bang for the buck and that the MREV2 didnt do very much on top of the spacer.....now im reading the total opposite....im reading that the MREV2 is the best for non rev-up motor, and the spacer just adds to it a bit....

I KNOW that the spacer and MREV2 would be best together...but FINALLY...can someone tell me for a NON REV-UP motor...if you just had to choose one....which would be better...the 5/16 spacer or MREV2?

thanks!

I have asked the same questions, as I had the same dilemma. I found the answer in the Top 100 Most Asked Questions section that I found during a search. The answer is that the MREV2, by itself, shows the best gains for our engine(non rev-up 287HP). I am waiting for mine as I type. I have read every forum related to this subject, including researching it on Motodyne's website. Good luck & happy buying.

MREV2 makes greater area under the curve than either the 5/16" or 1/2" spacer.

JKC350z

its still a good idea to have the 5/16 spacer on there as welll correct?

sunset...let me know how your mrev works out for you!

im looking for more usable powerfor daily driving rather that high-end for ...say for dragging

See page 2 of this thread.

It depends on what your A/F is if you have a 287 engine.
If you have a REVUP, definetly use both.

igetgreens

iTrader: (4)

but i also read that because on the 287 (non-revup) MREV2 gains compared to the 5/16 spacer gains is so little it is just better to get the spacer if money is an issue

Hydrazine

iTrader: (53)

That is when they are combined.

When combined, there is only an additional 2-6HP gained at various parts of the curve.

When money is an issue, just get the spacer.
