Good stuff, and it only took me to "BLUF" before I was certain you served - the rest of the writing style only cemented that. Should be quite the machine.Trying to reignite this thread. It seems appropriate, given that it is now in a Frankencar, and we’ve had to follow up on some hard-win lessons and trailblazing done by Doc.
If I screw up any of the technical issues, please defer to Skip’s version of events and knowledge if he chooses to post.
Quick Gist/BLUF: I ended up drooling over this thread when Doc was getting this build done. So I ended up calling Skip and putting some things together one winter on a smaller project, and it spiraled. Was just going to upgrade from a 2.8L KB on a short block that hadn’t been built yet. Mission creep took hold.
I now have this transmission, and thanks to the work that Skip and Doc put in, a similar project has taken shape- twin turbo car with a built engine. If you’re familiar with the Demon/TKM engine line, this would probably be considered “capable.”
Latest issues solved- getting a clutch for this that will handle the maximum power. If you’ve seen the IG page, that RPS quad carbon clutch is going on this. The ancillary issue was getting the right clutch slave fitted up- took a lot of shop time to get it fitted, and ended up with some machining being done on a Tilton to get one to fit to spec.
The picture above is some of Nate’s work in progress- having two sets of pipes for this on v-clamps. The one above is the drag/track pipe that is getting cutouts. The other one, because of emissions and inspection requirements, will be a cat pipe essentially being run at wastegate pressure for the street. I would never simply run the track setup outside of those conditions, and how dare anyone think or imply that 🤣
It’s been a long road, and it’s not done yet. But we are starting to get much closer to this thing hitting a dyno finally, and it couldn’t have happened without Doc stepping up on it as a trailblazer in the first place. A ridiculous amount of custom-now-production and one-off pieces came out of this, but hopefully the roadmap has been finally finished out for the project for future development/implementation for those looking to go this route.
I am pleased to share that we have specified this with a pair of PTE 7275 turbos, and a 3.40 pro out back. For those that implicitly understand what that will mean, the other uses for this will likely be on a road course- we are exploring another pumpkin for this to be swapped in that application and for general on-street use to prevent associated issues.
Why the timing now if the car isn’t quite done?
Well, a couple of reasons.
Skip and the guys have put up with me over the time period required to get this to this point, and it felt like they deserved a shout-out for one. Winter is coming, and that means build season for two. Finally, I’m preparing to exit the service, so this is attached by some manner to that time and timeframe, as date would have it. While that means it will likely sit for a lot of the winter… I will remain faithful to the experience of others over the course of it, as I hope this makes some serious passes at a number of events the next full season.
There are additional developments on the way, and I hope to be able to share those as well- I have a wrap ready to go on that may come out seriously hideous or not, but only time will tell and if I can help other people to avoid a potential mistake or get to see how something potentially cool turns out, great. Suffice to say, I have not seen it on the platform before, and I’m eager to see it after the execution.
In closing- games are afoot, and this did not occur in vain.
Soon.
What are the turbo specs and what are the camshaft specs?Trying to reignite this thread. It seems appropriate, given that it is now in a Frankencar, and we’ve had to follow up on some hard-win lessons and trailblazing done by Doc.

Dude I swear I started a hunt to see what happened with this transmission. I am at a real sticking point with my TT build and keeping it turned down to keep the manual transmission from blowing up, which I'm on my 3rd stock one.
I’m not hopeful to be out this year at the pace to current completion- I’m fairly certain snow will be flying at home before I get to pick it up. It’s been a long process, but I’m definitely looking forward to the result, and sure I’ll see ya and/or some other folks out and about next season somewhere.Dude I swear I started a hunt to see what happened with this transmission.

I hate the idea of going TH400 or 4l80 because I'm not a track only guy, I like fast long drives with friends.
In my search for a happy median the sequential is ideal but the 20k price before install is not. All the best and if you need any assists with the Turbo setup I absolutely love mine and she is FAST FAST at roll race events.
Invest in a higher-RPM valvetrain and extend the redline to 8000 RPM.Dude I swear I started a hunt to see what happened with this transmission. I am at a real sticking point with my TT build and keeping it turned down to keep the manual transmission from blowing up, which I'm on my 3rd stock one.

I mean, that’s definitely a method, and it would definitely make some pretty insane numbers doing it for sure 😁🤣Invest in a higher-RPM valvetrain and extend the redline to 8000 RPM.
Then with similar torque, you will have a lot more power.
