Exhaust manifold gaskets

[aspro]

have got a few stainless shim exhaust manifold gaskets comming soon 0.5 mm thick will also be doing individual ones for the 20v tubular manifold too.

Anyone interested just reply

Oh oh oh oh...

All in one stylee...is the original ss or a plated mild steel, anyone got an original one to check?

Wouldn't bother with the individual ones, mighty pita to fit all 5 at once...one always drops off when your nearly there...

I'm keen, price?

You working for a laser cutting company?

Interested!

Hi Carlos

The all in one for AAN ABY and ADU will be around £15-20 i am only doing these because i have had my exhaust manifold off a few times latley and the OEM gasket is now knackered and thought a tough stainless one could be reused a few times.

No i don't work for a laser cutting company i am a partner in a design agency in manchester. I have just kept my finger in the engineer / production pie over the years more of a hobby really. I like designing things :-)

I used to get a lot of manifold flanges water jet cut for people about a year ago but have been quiet for a while as i haven't had time design

Well...

I do Autocad at work, any good?

Nother idea...

If you do a steel 'all in one' inlet side, this could be used as a template for head/inlet manifold porting to match them when the proper gasket is fitted.

Just scribe around the inside of the template and hey presto...

The first test gasket has arrived so i will be fitting it soon to test its performance.

I can do a 20v inlet in stainless 0.5 thick if anyone wants one but is will be a one off.

Interested. For both please. I take it all aftermarket in and ex manifolds are made using the same profiles as the OEM ones at the mounting points?

Why stainless?
Wouldn't copper be better for a gasket?
The gasket needs to be softer than the mating surfaces to form a seal.
Or have I missed something?

Hi Bry

Copper would be ideal hi melt point and softer - problem is that laser cutting it is a bitch it loves to reflect the laser into the machine and melt things.

stainless should be fine

these will not be available untill i have tested the one i have as a proto.

Hi there

All the after market stuff is the same bolt pattern, i can't imagine it not being.

I need to check fitment on my head first before i release these but they should be available in 2 - 3 weeks.

Reason I ask is i've got a Wagner intake and the runners on my exhaust manny have individual mounting flanges fabbed onto them and aren't connected like OEM and others. Presumably one can just use standard gaskets otherwise? What do others use?

We discovered this the hard way, despite the manufacturer claiming that their machine would cut copper they failed to mention the reflection issues. They then billed us for thousands to replace the damaged mirrors and lens's. We now water jet cut all our copper.

[aspro]

We would use jet cut to do copper gaskets but find that the thin gauge material required flexed under the jet pressure.

Prototype has arrived so will be fitting it soon

Boink...

EM and IM gasket ready...one piece type?
