Also Motordyne's 1/2" spacer is still available and there's no plans to discontinue it at this time.

However, I didn’t pay attention the mods he has (maybe they weren’t even listed). So I am not indicating the lower collector wouldn’t work for different applications - I just don’t think the two sizes of spacers would make enough difference to be an issue.
I defer to you - I have always valued your opinion.
BTW - as far as 1/2" production, I guess I stand corrected. When I purchased mine Tony had just released the 5/16" and I thought I remembered him indicating he wasn’t going to continue to 1/2"... Either I misunderstood or he changed his mind.

Wasn't it showned that the MREV+ had no gains with the 1/2 spacers that was why it only came with the 5/16 spacers? If that was true with the MREV+, so why would you think the MREV v2 would work with the 1/2 spacers? The MREV v2 is a modified MREV+.
I believe u would see better gains with the 5/16 spacers + the MREV v2.

Mr_pharmD, the same reason(s) that let us believe that MREV+ will now provide gains on non-rev-up engine.
I will give up my 1/2” spacer for nothing. OK, only if it will interfere with FI one day.

The original focus for the RevUp engines installed with the original MREV set-up was not peak power . . . But additional power under the curve from the mid to upper mid ranges, which is what we got with much success.

The spacers + the MREV v2 combined might produce only 2-3extra peak hp is fine with me. I have maxed out my bolt on options with cats, exhaust, pulleys, spacers, intake, headers and even unichip. So if I can add a few extra ponies and stay away from cams, nos or FI then I'm willing to pay to still have a safe and reliable engine.
Dovla: As for the 1/2 spacers + the MREV v2. I understand the need to dyno it to be certain of the outcome but I have also read other post that you were disappointed from the dyno results on my350z and I just want to clarify the facts before u blame Tony for not telling you in the first place that the 1/2 spacers combined with v2 produced little gains.

Mr_pharmD, I blame nobody, and Tony couldn’t tell me because no one tried it yet.
There are many disappointed MD users with my dyno. Why? Because all of us with spacer still cant wipe out our smiles, so when new MD product arrived and unexpectedly showed minimal or no gains or loss, yes, it was disappointment. More so because it came from company that is way above others in this sea of shady companies with false claim products.

The results showed minimal and no gains bc it was already tested with the MREV+ that the 1/2 spacers were not synergistic when combined together. I believe that was the reason why the MREV+ and 1/2 spacers were never sold as a package deal. As I mention earlier, the MREV v2 is a ported version of the MREV+, therefore, the results should not have been a surprise to anyone that the gains were not seen when both are quite similar products.

I think you guys are missing a major reason WHY the MREV makes power. It is deshrouding the inlets due to the machining process. It's very similar to spacing the plenum up, except you are doing it on the inside.
My take on why the spaces make 1-2hp on top of the mrev.... and why I'll be swapping out lower plenums only

The Motordyne MREV+ lower collector! A universal stealth mod for use on any 350Z, G35, M35 and FX 35. When used with or without a spacer or aftermarket plenum, this modified lower collector will make substantial power gains.

I was referring to the MREV+. Before he updated his site to only carrying the MREV v2, there was the MREV+ with the 5/16 spacer package and never a MREV+ w/ 1/2 spacers. You are welcome to check out http://www.partshippers.com/index.ph...motordyne+350Z where they carried ALL of Tony's products up to the MREV+.
This was the package deal before the MREV v2:
Motordyne 5/16" Iso Thermal MREV Plus for G35 (http://www.partshippers.com/index.ph...roducts_id=910)
