I'm planning on installing an MREV2 & 5/16 spacer this weekend but I'm not sure whether I should buy a new stock manifold gasket or buy the thermal isolating gasket from MotorDyne.
I know it's only about a $20 diff but I can get the stock gasket after work at the dealership, no waiting.
The one from MD I have to order and wait for.

Anyone have any experience as to whether the MD gasket is that much more effective?
How much temp diff are we talking about?
BTW I'm in SoCal (Glendale) so it does get into the mid/high 90s in the summer.

Thanks.

 

I have one of those gaskets and if I ever take off my lower, I'm going to install it. Tony is adament about reducing heat and he's made a believer out of me. I'd get one even if it means having to wait a little. SoCal is no joke when in regards to heat.

I'm considering trying to get my lower plenum coated to try to lower the heat it absorbs.

 

So the Aramid gasket is prob more important then say the coolant control valve.
I assume not installing the valve would be like having it open the whole time.
I don't think it would get so cold down here that I would have issues with the engine after the install.

 

I'd recommend the aramid gasket and the iso thermal spacer. Install the CCV and leave it shut. Temps don't get cold enough here in SoCal to require warming of the plenum.

 

But I thought the whole idea of the CCV was to have the option to close it when the weather got too cold.
Am I incorrect on this?

 

Install gasket. Install the CCV but leave it closed. Obviously if you install it, you have the option of having it open or closed.

 

As Jeff said, installing the CCV will leave you the option to open or close it. ME recommends leave the CCV closed with atmospheric temps above 55F and open when it's below 55F.

 

Okay I just did some research ont he MotorDyne website and realized that the valve is to be closed when the temp is above 45 degrees.
LOL just now saw you post above.

I guess my ques is what function does this hose perform?
How does keeping it closed keep the plenum cooler?

I'm just trying to understand the whole process before I start modding my ride.

 

It does nothing. It's a waste. So ship it to me.

 

When the valve is open, it warms the plenum.

 

I just spoke to Tony from MD at length and he was extremely helpful, he definetely helped me understand the whole setup.
Awesome guy by the way.

Since I orig purchased the setup money has become quit tight for me.
I wanted to try and lower the cost of this whole install without taking any shortcuts.
He assured me that there would be no detrimental effects of not installing the MD gasket & CCV other than the 1-2hp gain I would have with them.
The plenum temp will remain the same as before the install.

The only reason I mention this is for anyone else that may come across this thread and possibly have the same questions as I did.

Thanks again guys, I really appreciated the help and insight.

 

Did you guys notice any difference in material or thickness between the oem gasket and the Aramid gasket from MD?
I have a chance to get one but I would have to wait to install until next week.
