Good stuff, Mark. Looks like you guys have a ton of room between the bores.

Here is a photo how we did my set-up:


I assume you guys are doing the same?

midget,

Just cleaned up a Cosworth head and installed some valves to mold a chamber for comparison to the special 'K'.   Poured the molding compound at 09:30, pics later.

Also molded a second cast of the 'K'.   If it's OK, the first one will be sent off to you to forward to your buddy Noonan.

Back to the flow adaptor for the throttle bodies . . . .

Bob,

Yes, we are going to use a hardened wire o-ring set in a groove cut into the barrel, coupled with the copper head gasket and a receiver groove cut into the head face.

Just like a Top Fuel Hemi . . .

He is why the 'K' will be EFI, and not carbureted . . . . . . .



MAJOR cranky with multiple Webers, go figure . . . .

Gotta get him off our backs, er, carbs . . . . . .

Let the little sh** buy his own laptop . . . . . .

Oh yeah, HAPPY FRIDAY!!

Deceased equestrian flailing is permissible, but I draw the line at Rhesus pieces.

I'll give the little fella kudos - at least he's trying to fix it, rather than simply replace it.

Fordboy, what model Cossie are you building?

I have a pile of Cosworth BDD's that I am cleaning up to flow test.    Just using one as an example to show chamber design differences between Cosworth and Rover.

The carbmonkey thought it would illustrate some issues that 'K' series racers complain about.

midget,

Ahem.    The carb monkey demands that I convey to you that he is not that all that happy with you!!

Apparently this all stems from the fact that you can't tell the difference between a Capuchin and a Rhesus, or a Franciscan and a Jesuit, or even a Trump and a Cruz . . . . .   :roll:

Bone up on your simians, religious orders, and politicians if you wanna stay out of trouble.

(Although I admit the rhyme was good and a rhyme with Capuchin is a tough one, it's still all about mistaking a Czech for a Slovak or vice versa!!)

It's the one run by Jefferies and Dolan. I don't remember a turbo and I understood it had been a Holoman and Moody factory effort prior to Doc and Jack getting it.They also had a bubble bach hatch that allowed them to run in another class. GT and Gas/fuel coup i think. GT guys thought it should be a coupe. Coupe guys wanted them to stay in GT. Lot of complaining.

Hey Mark, what's the ONE thing that really matters when building racing engines?  

"EVERYTHING."



OK, getting back to the fact that details matter . . . . . . .

More photos of the new solid copper head gasket, this time mated up with the cylinder head,


and Vs the stock Rover MLS gasket


rear segment




front segment



It appears to be a very good matchup to the cylinder head, although there are obviously some dimensional differences:

New copper gasket:  .031" thick x 76.5mm bore Ø    ~ 3.62cc

Rover MLS  gasket:  .091" thick x 82.85mm bore Ø  ("flat" MLS section .069" thick)   ~ 9.45cc      a 261% increase in just the gasket volume!!

This little detail would necessitate a dome volume increase of 5.83cc's, just to maintain compression ratio!!

Carbmonkey says:  "It's complicated."     Because every detail matters.

 :cheers:

No mystery that I like Cosworth engines. I have used two in my first lakester (BDG and YBM). Both were super reliable and made good power. Decades ago, when racing FSV, we were put in with FB (now Formula Atlantic) that used Lotus, BDD and BDA engines almost exclusively. I never got over the sound they made at full song.
