PHENOLIC SPACERS......by Outlaw Engineering - Page 3

tunnel ram effect? NAh, that stuff is for like..tornados and stuff. just a safe barrier to reduce heat transfer via conduction. I remember my old engine with the spacers, after a long drive, I could easilly hold my hand on the intake manifold, whereas I have a hard time doing so without them

....Mabey Ill do a little thermometer based expeiment when I re-install them

i think that the claim is 6%-10% at the crank. I dont know how much of an effect they have on the svx in terms of hp, but as eric said after spirited driving you can hold your hand on the manifold.

I am positive this has already been done, with pics.

This may mean nothing, or it may mean a lot of things, but after a while I felt as if these spacers lost effectiveness somewhere to the tune of 15 degrees. When freshly installed, the mani was always never hot. Recently it would become... somewhat hot, slightly warmer than warm. May just be my imagination.

"tunnel ram effect? NAh, that stuff is for like..tornados and stuff."

Um, what? Tornado "and stuff"? So you are talking about the fuel saver thing?

OK, not to mock, but, really?
Not to say that F1 is the tip top, but increased air velocity is the key to making power in the top end on a n/a motor. The eg33 is operating at half the revs so I was just wandering if the lower revs and no venturi effect has any part to play on our simple n/a motors. I'm not trying to be abrasive, just curious.

operating at half the revs?

Half the revs of an F1.

I was thinking they did like 12k to 14k. That data is several years old. Has it changed?

NikFu S. · #38 09-12-2007, 12:10 AM

19,000, which is a regulation limit.

NA engine builds may soon yeild 8k rev ranges, so you are not necessarily off on your statement.

What???
Before I installed the Outlaw spacers my intake manifold was 200F.
Just like the top of the engine block.
Now its 140F.

Granted I had it ceramic coated while it was off, but the spacers do help in stopping heat transfer.

Buy em, install em, and be happy!

sorry to bring back an old topic but I just want to know if I have to use the oem torq spec or they have a specific one?

James Scott · #41 09-10-2012, 07:41 PM

My recolection is.. the same Torque.. ? BUT, I had major problems with their spacers that had gaskets attached (with "goo") .. They slid sideways twice ..

Had to finally place OEM gaskets on both sides of new dry spacers! Just a warning.. ? I don't know how they ship them now??

Just got a set in the mail today actually. They don't have the "gooey" gaskets. The generic instructions that came with them say 14-18 ft-lbs of torque on the intake manifold gaskets.

I meant that the phenolic spacers came with attached gaskets. They dint work for me! The gaskets slowly slid after mounting.. .

Maybe they changed their gasket "goo" .. to hardening type.. ???

Yea, I understand what you meant. I saw some complaints about those in some older threads. They just did away with the gaskets, and now you have to order 2 sets of each OEM gasket separately from Subaru.

You are correct, Sir.
The factory gaskets work fine.
