I am confused when people say this. Just by using plain old school physics it can be shown that you should gain something by using a CAI just due to the fact that it pulls in the colder air. For there to be no gain would be almost like saying gravity doesn't work sometimes. If I am missing something please inform me.

 

The stock airbox is really good.

Thats it.

Thats the reason why you wont see much gain with aftermarket CAI or other forms of intakes.

 

The MREV2 will make your car go lean without an ECU flash due to your 1/2 spacer. MREV2 alone will give you around the same hp increase as your spacer. The rev-up engine benefits from having both but the 5at engine (non-rev up) only benefits from having one of them (without ecu retune).

With that being the case (for us non-rev-up peeps), and I were to choose one... Which one? Spacer or MREV2? How hard is the install for an MREV2 anyways? (I've replaced the fuel injectors on my other car on my own, so it probably doesn't matter either way, was just curious which mod is better/easier)

 

If you want to go true stealth, MREV2 is undetectable. The spacer is visible but hard to see if you have the engine cover on. They produce the same result. The install of the spacer is easier and its easier to put back to stock form. I personally would get the MREV2 if given the choice (I got mine before MREV2 came out).

 

"I've recieved a million requests asking if the MREV can be installed on the 280 HP engine. Unfortunatly I had to turn them all down because the MREV is simply a spacer with a lower plenum from the 280 HP engine. ...So if you have the 280 HP engine, all you need to do is install a spacer and you automatially have a MREV.

But you know of that machining process I have been doing to the MREV+ lower collectors to allow for more air flow?...

Well, I dynod it on a 280 HP engine and it made surprisingly good gains."

since your nonrev-up..i think this is what youre looking for:
"Lower Plenum Core exchange for the 280 HP engine is a go! I'll set up the Motordyne website to accomodate core exchanges."

i emailed them about this two days ago..still waiting for a reply

 

All emails replied to. You should have recieved it by now.

ohhhh yeh quotes from my previous post are from one of tonys old threads

(hope you dont mind)

 

Hey Tony,

are the gaskets reuseable when I take the spacers off? My installer had to take them off to get to the injectors for my sc install and noticed oil deposits on the gaskets and some inside the manifold. He was afraid that the gaskets arent reuseable and may cause a vaccum leak once he reinstalls everything. I actually have 2 gaskets (1 below and 1 above the spacers) so is it fine to reuse or do i need new gaskets?

sorry i would have pmed u but your box was full.

 

Yes. You can reuse them. They will get oily over time but its not a problem.

 

I currently have the Z-Tube and Stillen Intake on my car and I'm planning on going with the 5/16" spacer, MREV2, Exhaust, and then finish it off with a techno Reflash. From threads I've read in the past, I've read that any spacer added to the car along with an exhaust doesn't work well. Has any one done some times on the track and noticed either their time slow down when adding a spacer when already having an exhaust or vise versa?

 

I've done tons of testing with and without exhaust on many diferent cars. Exhaust mods never adversely affects the peformance of plenum mods.
