Would doubling them up on the IM and/or TB be beneficial? Thought about this the other day, I'd like to hear your opinions

Ya of couse it would insulate more the thicker you made them.
But it could hurt flow if not matched up nicely and staggerd in the ports.

When I ran a mdx spacer I ran 2 and the manifold would be touchable where you could hold your hand on it.

i can put my balls on the manifold after driving it with just on thermal spacer.. but 2 would def be better. but not 2 xs better IMHO

if doubling them was so beneficial they would have made them that thick to begin with so i would think

Getting an IM spacer is definitely a good mod. Not too expensive, and it has some proven gains.

As for the TB spacer, I would just bypass the TB coolant lines to it. Unless you live in a very very cold climate, it's just going to slow down your car with no benefit. Still, a TB spacer won't hurt.

Don't listen to anyone claiming the added length does anything. The spacer doesn't matter, it's all about the temperature.

Not understanding you here.
Where are you saying lenth does nothing.

Because lenth anywhere does something.
adding lenth to the manifold spacer lenthening the runners will bring the torque down in the power band.
And lenth at the TB spacer will add volume to the manifold and will give you more high rpm hp.

So witch are you saying does nothing ?
Changing "Lenth" as you say anywhere does something.

No I mean it does nothing. It is so insignificant, it wouldn't be measurable. Some university did a test for the TB spacer, and determined that it STARTED to make a measurable difference if the TB spacer was a yard long (or maybe a meter). Either way, any practical sized TB spacer will do nothing in terms of length.

They didn't test the IM spacer, so I can't attest to that.

I didnt notice a damn difference when I installed the TB spacer.

i didn't notice anything when i added my tb spacer and gaskets but who can feel a couple hp anyways.. no one still i like the way it looks and i'm sure it does something to help..

i wanna do the coolant line bypass but it gets cold up here and i don't wanna compromise the driveability

Is their anywhere to buy the thremo gasket stuff in a sheet to make your own spacers/throttle body gaskets ?

The mica sheets ?

speaking of putting your balls on it ... anyone ever check out the UCM thread in the '04+ TL section ?

How about a link ?
Anyone consider running thermal gaskets under the lower runners.
I bet when combining with the manifold gasket and TB gaskets their would be a noticeable gain.

Are the thermal gaskets fuel resistant?

richardparker

Not sure.
It might be worth looking into if we could find some thin super high temp material since that is the first place the enternal heat enters the intake tract.

It's not going to work. Anything that thin isn't going to insulate from the heat and anything thicker is going to make the runners not line up with the plenum. You could try milling 1/8" or more off the bottom, then use an 1/8" phenolic spacer.

You could try to find a way to circulate air around the runners. Airflow around the runners will cool them down better than trying to insulate them from the heat.

Anybody port their uppers and lowers to the thermo gasket? When I did mine the runner diameter was at least 1/4" smaller than the hole in the thermo spacers. Seems like putting two gaskets will make flow worse unless the runners matched the gasket.

Best Idea for a new mod !

What's UCM ?

Sorry, too lazy to read 14 pages. Is all this just to vent the hot underhood air? I seen graphs where intake air temps were cooler but if air heats up in the runners to the original temps, there won't be any gains. Were track times improved? You can't use a dyno because using a fan for airflow isn't anywhere near real world.

Were the holes in the cowl to let cold air in and exit out the bottom?

You could use all the butt dynos and ball sac thermometers you want but if track times don't improve, you haven't accomplished anything.

typeR

shortest version i can give you is it started at removing that hood cowl by the windshield then others just holes in it ... it allows a place for the trapped hot air to go ... measurements were taking and it seems to work well ...

summry even with thermoblok spacers the mani got warm still while driving.. with the cowl mod it was cool to the touch if the mani cooled off that much it stands to reason the lowers are cooler as well it should also stand to reason the ecu is going to add timing baring any other reasons not to ...i.e. knock etc ...
