Hey Everyone,

We had some requests for phenolic spacers, so we ran a batch!

Helps cool IATs down and simple install. These go under your plenums and require 2 new gaskets each. (not included) This is a set of 2 spacers.

You ought to at least have your listing show a picture of the spacers for the 55 (unless my car lost two cylinders without me finding out about it).

How do yours compare to the ones Evosport sells for $349?

SterlingE55

What kind of IAT difference could we expect?

What material are they made of?

Hopefully Jake can expand on it but I think the mateial is phenolic resin. It has good heat resistive properties.

I have evosport phenolic spacers, but have never tested IATs. The spacers went in when I did an 80mm TB and shorty headers so I can't to speak to specific gains if any.

Apologies to the OP but I've recently removed my VRP versions.

I was more concerned with the change in injector distance from the valves, and a less smooth inlet tract. While phenolics do create a barrier to heat transfer I just don't think they work in this application.

You got a hot motor & very hot super charger.. so what's keeping what from getting hotter? YMMV.

I know phenolic spacers have been somewhat popular in the mustang crowd before, but I also don't see ow it would really help here as the motor and blower each produce a good amount of heat on there own.

The mustang 5.0 guys used it to keep the large upper half of the intake isolated from the hot lower intake manifold but I also just can't really see how this would help in the 55 motors. The spacers are meant to significantly reduce heat transfer through the contact area, doesn't seem to make sense here.

Toadster

would be interesting to see someone make a 'cooled' version of these...
It would be neat to have a peltier version where it would be electrically cooled - the water condensation would only help reduce AITs - right?

BBBSS

Your being a Toadster again Toad. lol

Toadster

could be interesting a cooling layer in between - probably too much stress on the components though - you'd be actively trying to cool down the layer in between while both layer are trying to heat the peltier...

maybe it would need a separate battery LOL

cal1

Having tried to keep overclocked CPUs cool a few years back, I always wondered about a peltier as a cooling solution in our 55Ks. maybe the power issue (electric) is the problem.

phenolic resin indeed

lol good point and will get that updated. They are cheaper lol...thats about it

I can't comment on the VRP product as I never used them. Ours don't change the position of the injectors at all. They simply go between the plenums and riser from the sc. IE where the gasket is...

The plenums are the same dimensions as the gasket.

Think of it this way, do a run and put your hand on top of the plenum. It is VERY hot and you won't have your hand there long. Now do the same with spacers and the plenum is warm but not extremely hot. It helps with the metal to metal heat transfer. The plenums will still heat soak eventually, but this slows the process.


see above...

SterlingE55

Send me a set and I'll give you some before and after IAT data.

HeissRod

I'm running that spacer. Not sure if it really did anything or not...

BBBSS

Everything will heat soak from engine bay temps after a lil time. It gives you a lil more time after a cold start before parts heat up. Once you've been running for a while it does basically nothing. If you're in there anyway and have a few bucks to burn it won't hurt but only does so much for so long before its just along for the ride. Just my opinion though.

stevebez

My VRP pheonolics are about 5-7mm thick. Moving the inlet tract / S/C assembly higher moves the injectors with them.

So the injector is that 7mm further from the inlet valve. I imagine this is less than optimal as MB would have defined the distance initally as an optimal one. Whether this matters materially in real life I dont know... but I know its something thats changed from stock that we are perhaps not taking into account.

loungn14

ah now I get what you are saying. Our spacers are for the plenums, not for under the supercharger. Injectors don't move...the spacers sit under the plenum.

stevebez

Ah so for the surge tanks ?!?! Gotcha ... fair enuf. I think this could have some value then.

those are the upper spacers not the lower, i've been running those v6 version on my c32 from 3 years and you can feel the difference in heat when you put your hands below the spacers(SC runners) and on top of the spacers(surge tank). they really help to keep the surge tanks from the heat of the engine/sc.
if someone have the lower one for sale let me know(v6 or v8).

i just mailed Jerry, the spacers for V8 are the lower and the V6 are upper,
but the V8 upper will come soon.
