ok ok ... conclusion,
on a non-rev engine, md 5/16" vs. md5/16+mrev2 ..
the results are almost the same and its not worth of money making a combo on a non-rev?

 

Actually from what I read, you were implying that if you use both together, you will need a tune. But not if you use one or the other. That implies that you meant that using both together will make 2x the power. IMHO, from what I read about using the mrev on a non-revup, that's not true. Nor do you need a tune if you use this combo on a non rev. At least that's what I've read.

If one has an exhaust/intake and cats already, adding a spacer will definately requirea tune though.

 

look the MREV2+5/16 spacer combo was designed for the rev-up motor. you have a non-revup, for the BEST gains JUST buy the MREV2 and call it a day. if ya wanna save some ca$h JUST get the the 5/16 spacer, you'll get more than 1/2 the performance gains of JUST the MREV2 for 1/2 the price and 1/2 the install time.

 

is there a dyno sheet that verifies the mrev on a non-rev?

 

I see ... for now because money is a issue im going for 5/16".
But my question was, if after I add the MREV2 it will give me like some more power? like 5-10hp more ?
like,
spacer hp+tq gain = ?
mrev2 hp+tq gain = ?
spacer+mrev2 hp+tq gain = ?

and my other question is ... I have AEM CAI but I converted to SRI. and grouding kit without doing a tune.
If I put a blitz nur spec catback exhaust. and the spacer. Do I have to tune?

 

WOW, okay... i'm goin' of MD results here, what else do i need to say? we all know you can't just add HP/TQ gains all up when using mods together, duh. remember all of MD's results are from testing individual parts in specific combos. stock the VQ runs a lil lean but w/enough breather mods our ECU has been known to overcompensate and make the engine run rich. so someone w/other unknown mods could've ran the combo on a non-revup w/o a tune, sure BUT this guy is pretty stock. i'm not sayin' to run both, i'm just sayin' if you do, you'll need a tune. i have a non-revup and i run just the 5/16 spacer and i'm tuned... smarter buy for me. but this guy's askin' for what's gonna make a big difference. in this case the MREV2 alone will.

 

There have been multiple pages of debate/ dyno (pilot guy who has done the research was Aceman if I recall correctly) over on the Z forum showing that you do gain more (area under curve) with MREV2 on a non-revup engine when compared to a 5/16 spacer. That being said, he also had luck with MREV2 + 5/16 spacer on his non-revup engine, but note that he has a tune.

Note also that Tony@MD recommended buyers to get either the MREV2 or 5/16 spacer; and only get both if there exists a proper tune to account for the extra plenum volume/ airflow.

 

ACtually that's good info.

but when I asked Tony if I'd gain much with my Crawford plenum + Mrev, he only said it would be worth a few hp. From the dynos, the crawford plenum wasn't that much diff (little lower) than the various spacers. That's where I was coming from.

 

no you won't add big peak gains buy adding the MREV2, after the fact. if anything you just pick up the mid-range. after a tune w/just the spacer you can pick up a lot of mid anyway. that's way i just stuck w/the spacer. as far as a tune goes, a tune on a stock G will see gains. do you need one for ur current mods??? no. also the Blitz nur-spec is an axle back and won't need a tune either.

 

Tony himself has stated many times that for the non-revup, the spacer itself is the recommended modification. Where as for the Revup, both the MREV2 + Spacer is the best combination.

I think we will stick with the words of the creater himself

Revup: Spacer + MREV2

Non Revup : Spacer

You can always use the MREV2 on the non-revup, but its not going to give you the gains of the revup.

thank you Jeff for not makin' this drag on... i get where ur comin' from. yeah, it's just not worth the $$$(to me). the gain are there though.

 

I totally understand you guys and thank you for all those posted on this thread ^^
Like I said Money is a Issue for me, thats why I asked before (hp+tq gain)
We all know MREV2 alone > MD Spacer 5/16" Alone
But If a MREV2+SPACER will make much more than MREV2 alone.
if yes, I could just buy it today and install it and after I save some more money I add the MREV2.
BUT, If not Im just going to save some more money for MREV2.
=D

Thank all you guys !!

 

im sorry guys i was writting down my last post .. when i posted .. BANG ! a lot of replies =)

my bad !

 

yeah, i recommend just the spacer too... what's ur point? the MREV2 alone Vs the spacer alone has been proven the the MREV has "better" gains(by MD and others). but it twice the price and not near twice the gain, so yeah of course it's recommended to just go w/the spacer. Tony's a good guy and MD is a good company so i wouldn't expect any less.

 

Ok guys thank you all =)
MD Spacer 5/16" FTW.
now basic or iso-thermal ? =D
hehe ..just kidding !

Even stock g's can get a lil gain of power by tuning ?
So should I take my car to tune after I put the spacers and exhaust?
