Building a Twincharged Cummins Diesel Ultra 4 Race Car Start to Finish

Here’s a narrated video of my twincharged mid engine Cummins powered ultra 4 race car build. I used a Whipple 200r supercharger and Phatshaft 62 turbo to twincharge the engine. The tranny is a 47rh with a manual shift body and a shortened tail housing. The transfer case is an np205 with modified shift rails billet bearing retainers. Both the front and rear axles are gm 14 bolt with a full spool if the front and locker in the rear.

Cool build. I was waiting to hear it fire up

I have lots of videos with it running. It sounds insane. All the neighbors for a quarter mile can hear when I take it out.

I like your build good job :) I always thought there should be more diesels racing out in KOH with all that torque . Would love to see a video with the truck on the dyno?
