Phenolic Spacers on AU V8's

Do you think Phenolic spacers work? And are they worth the money (ie: bang 4 buck).

Cheers

[Tech Trainer]

Has anyone had any luck fitting one of these to an AU without the manifold hitting the bonnet?

If so how thick was the spacer and did you modify anything to allow it to clear the bonnet?

As for do they work? Certainly do!

[Free347]

A 3/8" spacer under a high series bonnet was ok when I last had an explorer intake on. The edelbrock 5.0 rubbed the lining just a little.

got one coming for mine.

whats a fenolic spacer?

[philstoj]

I have a 1/2" one fitted to mine, and yes it does just hit the bonnet of the XR, but only just.(probably worse when launching hard)

What i find best about it is that it keeps the upper manifold very cool, which has got to be better.

Ok, i think the material used to make it is refered to as phenolic, but what it is is a spacer which seperates the upper and lower intake manifolds.
Its purpose is to stop heat transfer between the intakes, and also it lengthens the runners and gives you a bit more torque aswell.

Remember, google is your friend.

Phenolic smenolic im getting blown....................Maybe

But as has been said the spacers do work and keep the upper nice and cool. I actually didnt notice how cool the upper was until i fitted my Edelbrock and now having no spacer you can feel the heat.

What sort of $$$ are they worth??? they aint hard to fit.. and i have a high series car

so? whats your point?

[NeishaXR8_347]

He is just pointing out that he has a T-series and we dont, LOL.

They are about the $120 on mark.

[DavesXr8]

Where do you get them from?
any links?

How hard is it to fit?

Would it make any diff to an edit geting 1 in 2-3weeks so if the spacer is good enough then i will fit it b4 the edit.

Or will it not make any diff.

Thanks

BPT motorsport sell them and also Bluepower was getting some in and maybe sitting there waiting they are site sponsors, Defenantly get it before the edit though as its nice to have a tune to suit what you actually have at the time.

As for fitting they are very easy you can just sit the upper to the side once you undo the bolts or get someone to lift it whilst you install the spacer and then bolt it back up.

It will make a differance to the upper intake manifold which will keep the tune more stable aswell as increasing the runner length slightly which helps torque.

[DavesXr8]

Cool

So what thickness should you get?

I have the low bonnet.

Ok just read BPTs site they say 12mm for the 220kw i have the 200kw will it still work?

Thanks again

[NeishaXR8_347]

Yes the 12mm one is the one that i had on mine, will even work with a 175kw as long as it has the explorer manifold which all AU V8's have so your set.

Hi All,

Is this mod worth doing while I'm getting my cam/springs/rockers replaced?

Seems like a worthwhile addition while the mechanics doing the other mods.

[AU2PWR]

do they make em for the 6

Not sure Daniel but maybe someone could get some organized if enough are wanted.

Yes it would be best to do it while it all apart.

Did the mainifold hit the bonnet?

The 12mm one that i had didnt touch the bonnet at all, but before that i had a 1/2inch one and it rubbed the underlay slightly just like a little rub mark and didnt touch the bonnet. But all that said the only reason i believe it rubbed the underlay is because one of my black clips that hold it on the bonnet was broken.

[b2tf]

speaking of said 12mm spacer shaun where are the bolts for it! :

Wouldn't there be less than 1mm difference between the two? If so why did you change it?

[Psycho Chicken]

Speaking of bolts make sure you get the spacer to suit the Explorer manifold not the GT40 one. The Explorer has 4 longs bolts, GT40 has 2 long bolts.

I paid about $100 delivered from HPW.

Does it do anything? Wouldn't know, it's sitting on the shelf still.

Sorry i should have explained, i had the 1/2 one when my engine was stock with just a filter and exhaust. I then decided to build up a warm 5L and while it was out it was slightly damaged and i didnt feel comfortable using it, so i then spoke to BPT and had a 12mm one sent down to replace it.

Mate these missing bolts are driving me up the wall, as i said the choice is yours. I used the stockers but your choice. Dont leave anything on the bench as it will go missing (gf) and you get the line from them "i havent even touched them and i havent seen them".

will the stock bolts be big enough though? i thought you needed longer bolts to put the spacer in?

[NeishaXR8_347]

With the spacer and the stock bolts there is still 8-9mm of thread into the lower, you only need the actual diam of the thread to be in and you get full strength, as in if the bolt has a 8mm thread then you need 8mm onto a nut or in this case the lower and you have full strength. you cant do these bolts tight with the spacer they need hand tight only.

[philstoj]

They do fit austin as my 13mm spacer still uses most of the original bolts.
and as shaun said, be careful, make sure you follow the factory tightening sequence and not any more than a good nip up.
