The Iso Thermal allows your plenum assembly to run a lot cooler.

OK here we go again. I have just got back in town & saw all these comments. I went back to the Top 100 Questions Thread & it states very clearly that for the 287HP(non rev-up) engine that the MREV2 w/o spacer is best gains. The 287 engine has the MREV as a stock lower plenum according to that same forum. So, my question is, again, which post is correct? Is the answer in the "Top 100 Questions" wrong? I want to buy the right thing.

 

The MREV2 is a modified version of the stock plenum.

It is this modification that makes the gains.

As Jim Carey says in Liar Liar, "& the truth shall set you free!" Thanks for your help.

 

What exactly do you mean here?

 

I think it was a compliment. So many people throughout the forum have twisted what seems to be a simple answer. You are "the horses mouth" hence the "truth".

 

Right on. I was a little confused for a second there!

 

hydrazine has the hardest explanation of his product of all, lmao i been through counteless threads and its the same question over and over ...good patience and Cus support brotha. U willbe hearing from me shortly when i put some more milage on my revup brotha.

 

i would love to get this mod, but i have had oil consumption and pining issues since day 1 and am afraid to mod.

i bought the car to mod, but was hoping to take the chance of a voided warranty with the car running as it should stock.

 

Get all that stuff fixed before you do anything!
Otherwise you can run the risk of having the dealer blame everything on your mods.

Some dealerships can be cool and some can be rotten.
Have a transmission problem?... It must be caused by your tinted windows!
Have an oil consumption problem?... It must be cause by thoes aftermarket speakers you have in the door!

 

I have a revup with the MREV mod (spacer+non revup lower plenum). Am I missing anything here? MREV2 is a modified version of the MREV? Please explain...thanks!

 

I believe for the revup the optimum combo nation for powe rwould be the iso thermal mrev2 and 5/1/2 spacer iso thermal and call it a day. Tuning would also reap the best out of this mod aswell. But it will get u the best results with a slight variation at the top end with a 3 hp -+ correction which varies car to car. Correct me if im wrong hyrdra, is my understanding good.

 

MREV isn't actually a stock part.

When the first version of the MREV kit came out, it consited of a stock 287 lower plenum and a plenum spacer. This was used only on the REVUP engine and it was called a MREV kit.

But then the design evolved, where the stock 287 lower plenum was modified for additional gains. This kit was called the MREV+. It was later found that this modification was also effective on the 287 engine.

Then additional modifications were made to the lower plenum for more gains and it was called MREV2.

 

got'cha. so what sort of additional gains are we looking at for MREV2 vs my MREV in relative terms roughly?

 

You got it, very much a compliment. I wanted the real truth before I ordered & it was provided, thanks again

 

bump, anyone?

 

i have the TN kit and i love it... i jus have the polished plenum on right now (bought it like that) mines an 03 and im running rich. so would the mrev+spacer not be a good add on?

 

bump again for the MREV2 vs MREV performance differences...

 

There was a guy who recently did a pre/post dyno install of the two. He posted the plots on this board.

Do a search on it. He did it on a G35 and it certaintly made gains.

 

thanks will search. standard MREV already a great improvement over stock, best mod I have for sure
