The initial prototype is not quite representative of the new production parts but I'll be picking up the 2nd proto tomorrow it looks like. Will throw that on the scale and see where we're at.

Unfortunately it was impossible to use an OTS O-ring on the AV covers like the PV ones so we had to go custom.

I'll be sure to make these available to valve cover buyers for years to come. They are not too expensive so people could stock up if they are worried about future supply and they should be reusable 2-3 times at least.

Default Valve covers

If you would, put, my name on the list for a set of the angle head valve covers. Thank you

Default 2nd Prototype



Off the mill today. Will weigh and leak test it next time I'm at work.

Default Put me down for 4

I love the look. 'F4 Raptor' engraving if that is an option.
Thanks
Ron

Thanks.

If you provide the graphic as a PDF or other common vector file, we can laser etch it on there.

Default On The Scale

I got the VCs on the scale today.

Stock steel cover with standard thick silicone gasket is 238 grams.

The SDS cover with our gasket is coming in at 188 grams. Barring differences in fastener weight, looks like you'd save around 50 grams per cover.

Static leak test completed over the weekend was successful. We'll be machining 4 pre-production covers late this week hopefully to complete engine testing on soon.

We'll place the gasket order tomorrow to get those in process so they don't delay deliveries.

Default Pre-production

We made 4 pre-production covers which will go out to a beta tester this week for on-engine evaluation.



Once we're satisfied that they perform as designed, we'll do a production run.

So theoretically a weight savings of 0.66 lbs if used on a 6 cyl. But then you're locked into a custom gasket, though I imagine that wouldn't be hard to source yourself if you needed. What are the other advantages of this product?
