Just bought a car (not goin to say anymore on it so dont ask) that has the spacer between the head and inlet manifold ...Basically an inch thick metal gasket!......Apparently it works You heard of this guys i thought the spacer was on the plenum LOL.

 

Dont know, but suprised you wasnt at the piston heads meet, loads of ferraris there

 

depends on the application, some tuners use them to help prevent heat soak into the inlet, would nheed to know what engine it it to knoe if applicable though,

 

Danny YB of course!

 

What ya think I am , fuckin mind reader!!! you change your dreams 3 times per night!

back to ya spacer, aint got a clue.

 

Danny all my dreams are YB ....ventured over to the RB26 but soon got rid and never tempted to go back

 

doesnt increasing the port length make the air flow faster a bit like how a riffle barrel works ?

 

Replica...you know you might be on to something there.....Tuners?

 

BTTT!

 

Its normally a plate made from a low conductive material used to isolate the inlet from heat. Many BMW's use this method as std.

 

It also increses runner length which helps make more torque down low but I hear it hurts high RPM performance.

 

A lot of those theorys go out of the window when ur talkin forced induction.

 

making it narrower would make it go faster

showing your excellent knowledge of basic physics again phil

 

But remember the boost has lag.

 

sarcasm at its finest

 

remember to rifle it then as well,otherwise its just a gun!

 

why did ex owner say it was there? any other obvious reason in the engine bay why it is there as my car has one but for a very different reason.

 

I reckon on it being a manifold insulator too! We used to make loads and loads of these for lots of different cars (there were even a number of race teams which bought them)

Only ever made a few YB (all 3/4" IIRC) ones though which look like:



Most of the spacers were 1/4" thick (6.4mm): In comparison to a normal gasket at about 0.6mm thick the 6.4mm spacers would conduct between two hundred and a thousand times less heat.

hi

why did you stop making them for YBs? they dont work?
