6.1L Stroker 12V Cummins Engine Build | 800 HP | Power Driven Diesel

I would love to see a full build sheet on this motor

My favorite diesel channel!

Holy shit! I’ve never heard of doing a 5.9 top end 6.7 bottom end Cummins. Raising the compression ratio made me drool. Mechanical Mafia!!!

I raced a daily driven shop truck 1994 Dodge 2500 2wd with over 220,000 miles on it back in 2005. My fastest 1/8 was 6.9 et @105 and one of the fastest 1/4 was 11.06 @ 128 mph. Running between 1 and 2 stages of N2o. The 11.06 @128 was at a DHRA event at Famoso raceway back 2008 on a single shot of N2o. The engine was running had orginal stock internals and running "stock" head bolts. Turbo was a High Tech 66 with a stainless steal 16cm turbine housing. Injection pump was our in house 13mm pump with a Fass hpfp . The cam gear was welded. Transmission 47RH was built by Joe Webb at Suncoast transmission running their Pro Lock 5 disc torque converter. Detroit locker with slicks and Cal Tracs in the rear. I got a call from Jason Sands one day from Diesel Power Magazine. Asking about how a group of us was getting away with running stock head bolts that he was doing a article on. Garmon Diesel was also running stock head bolts as well. My Theory or what i did and what Garmon was doing is to torque the head bolts in 5 ft lbs increments. Also a high milage head gasket is better then a new head gasket. Why? My Theory is the head gasket, block and cylinder head lap into them selves over time from thermal heat cycles. I raced the truck from 2005 to 2010 and drove it between races every day. I found out the hard way 2 stages of N2o on a single without a external gate only last 2 passes before the turbo comes apart at 80+ psi of boost. But the long block never gave up. I ended up pulling the head because of the aluminium turbine shrapnel getting into the valves. The cylinder walls where perfect no scratches. I do agree head studs are better then head bolts. But we proved how far you can push stock components on these engines. They will go farther then most people think. Nobody thinks to retorqued the head bolts. Thats the 1st thing you should do before turning up these engines. Half the time there under torqued from factory.

The attention to detail from you guys makes your channel interesting to watch. Plus you respond to most all questions. So many YouTubers get so big they fail to even address any questions or comments. Keep up the good work. Looking forward to owning a 800hp Cummins some day and you guys will definitely get my support and money spent. 800hp and 20mpg would be incredible.

First time I've ever heard of a diesel stroker engine, didn't know that was possible. That's awesome, 🤘👌

Bought my first Cummins in 1991 ... this is good stuff

I love the way you explain and teach!! It’s great to watch your videos .. I have been to turbo school and have learned lots. It’s nice to learn from the pros! Keep up the great work guys!! I love this build!!! Great design and build quality !! Great motor!!Awesome work!!

Probably the only guys I would trust a giveaway truck from

as always a great and informative video, thanks guys!!!

Agnes, Tina,... I LOVE the names you come up with for these trucks! 😂😍😂 That engine sounds like a beauty! Might have to do a "Fummins" swap down the road when my 6.4 F-350 bites the bullet. Great job, guys! 🙌

In the UK our diesel vehicles are embarrassing, 2 ltr is about your max these days. Love watching all your shows, can't believe your knowledge on these things, guess that's through trial and error. If I win will you send it to the UK???? Cheers guys. Keep up braking stuff.
