phenolic spacers for the rs4?

[andream88]

pleasee

[jc..]

there is an arguement that by reducing the amount of heat soak from head to IM that you are increasing the heat in the head. I would rather have a head that ran a couple of degrees cooler.
Air also demonstrates laminar flow charateristics creating an insulating boundary layer or slower air while the central core runs at a faster rate.
not flaming the idea, would just rather see someone do a true temp and dyno test before and after

Can you tell me wich one i have to buy please?

Thank you

dont get either. get them from VAST PERFORMANCE.

the others are bollocks. VAST is a solid 1-piece design, that isnt all cut apart like the other gaskets. the extra cuts weaken the design. furthermore, the Phenolic material VAST uses is more solid, that in conjunction w the 1-piece design makes them less likely to break down.

i have the VAST and ive beat the hell out of mine, and when i recently pulled them out, they were perfect. VAST FTW.

that is all.

I have installed some on mine - with ceramic manifolds and some one of ceramic down pipes and its as cool as a cucumber down there (the engine bay that is)

P.S. wll give some feed back on temps when I can get it mapped and running full speed.

I talked with some engineers here in Italy, and EVERYONE told me not to buy them.
It's a matter of heat dissipation etc.....

I think jc makes a good point here don't you think?

Heatsoak, or lack of, must make a difference to the heads...... almost equalling out any benefits you may get? Any thoughts guys?

[andream88]

Yes i agree with you and jc.
In fact i spent that money on the AutoSpeed DTS

Bye!!

where the hell do you YOYO's get your info? the phenolics act as a spacer and lengthens the runners. the longer runner allows the air to cool and sends cooler air into the head -it also send more air into the head.

now tell me, how is COOLER air going to heat up the head?

these have been dyno tested at EPLabs. after multiple hard runs, it kept the car cooler and ran consistently to its hp/tq #'s. i reiterate, multiple HARD RUNS.

also, these were good for ~5hp/tq easily.

that is all.

I'm afraid I have to agree...

There is far too much heat in the RS4 engine bay - when the car is up to working temp - if you tune the car there is more heat - which is a by product of power - you need to get rid of this heat in a turbo engine otherwise the performance will drop off - as we all know.

Getting the heat away from the induced air is the problem, and anything that helps must be good - hence larger intercoolers, water injection etc etc...

All i can say is that my engine bay now is a lot cooler than before, and I'm getting more bhp - so I am happy with the car set up.

R.

ZKNY, are you an engineer?
I think you don't.

If you use phenolic spacers, you will block heat dissipation from the HEAD to the intake manifold. And this thing is really dangerous. Cosworth engineers, in their project didn't include modifications like this one. I was suggested to buy a GOOD fmic instead of the phenolic spacers
Moreover, if you decide to buy the phenolic spacers..bring yourself a 5mm type. The 10mm ones are TOO thick.

This is all good debate, and very interesting (seeing as how I am thinking of putting phenolics on my car) - but I guess we need good old empirical evidence now to settle this one way or the other. Anyone got any?

the evidence is CLEAR. and88 is talkin out of his ass -what he is sayin makes no sense.

pls re-read my post. not only do i know from experience, but others have logged, as well as EPL w the dyno tests. that is all.

what the hell are you talking about, LOL!!!

there is no dissipation from the head to the manifold. its the other way around, and that is what PHENOLICS do.. they help cool the air from the intake manifold to the head (i am repeating myself, read my thread -its all there).

the phenolics are a safe bet and add a lil HP. not too many mods that are this simple and add HP/TQ. every little bit helps. if anyone is looking for more air, i have lines to CUSTOM INTAKE MANIFOLDS, you cant find them anywhere in the world.

[andream88]

You are really RUDE.

However it doesnt' matter, i won't use phenolic on my car.

ciao!

si si... no no!

im not rude, rather... we call it, HARSH... =D
