yup that would be the ultimate build ,willing to sell a kidney.When will we see a full billet 3.5L race block?

It looks like a ton of power on much lower boost than is traditional. It's a beautiful thing. Nice and smooth curves.
Have you guys taken any video footage of the new engine in action? If so, link please.
So you guys are testing with the sequential box and A/T car, correct? Any tests with the zf manual?
The ZF manual is the standard 6MT, which all of our runs, 1/4 mile times, 1/2 mile traps, etc. have been done with prior to going to the sequential. We won't be doing further testing on the 6MT as it's not necessary -is there something specific you're looking for that you want test results for? 6MT is pretty well understood.
I’m confused. The sleeves fill the spaces in the stock block around the cylinders where coolant goes. Thus adding sleeves reduces surface area in the block for the coolant. Less surface area = less cooling. How do your sleeves not reduce cooling?
Rebello has big history in road racing, where motors just get the shit kicked out of them. There are different kinds of sleeves for different applications. @Jeffman you'd have to talk with Rebello to get into the details. No doubt in my mind, though, their bottom end is going to be the shizzle.

Yes, I’m familiar with the ZF manual. I’m just curious how they perform together. Not really interested in 1/4 or 1/2 mile times. I do a fair amount of canyon driving though, so just curious about overall drivability with the built motor and MT. Any nuances or distinctions you encountered during testing that wouldn’t apply to an Auto or sequential trans. I understand you guys are setting records with your builds and I respect that. However, I’m looking for a solid performing, reliable car I can open up in the mountains.. so different goals, I suppose.
Edit: I’m sure your guys are looking for solid performance and reliable cars too. My car is more for personal use than competition. Opposite may be said for your builds. Which is why I brought up different goals. Either way, I plan to own one of these motors once available. Just want to know what to expect.

The built motor and the 6MT? They work exactly the same together as a stock motor and a 6MT. Drivability is not impacted in any meaningful metric. It's a durable, fun, but slow to shift unit that can handle a ton of power and a lot of abuse. Just make sure you choose a clutch that can handle what you want to put through it -we used the spec twin disk, Tony liked that a lot and said the drivability was excellent vs. the Spec Stage 3+, which he welded on aggressive launching.
Thanks Chris! Well, I’ve been putting my money away for a little while now that I know there’s a viable option out there. Can’t wait to get my hands on one.
How did you guys get the sequential working electronically? Did you have to go standalone?
We are using the factory DME. We're keeping some things quiet for now -all in due time.
Which is amusing in its own right. A $20k engine, with a $10k turbo setup, hooked up to a $15k trans being run by a $50 android app. Maybe that’s the ultimate sales pitch for MHD though.

Can you PM me some info on darton/rebello sleeves? I currently am ready to have my block sleeved. Machine shop ready. However it's impossible to find info on what is available. I've been looking for existing sleeves for a couple weeks now.
