Hi Greg! How are you doing?! Dude thanks for the videos! Pete and Kevin are true legends! Your work is invaluable in keeping this knowledge alive. What do you think of a series like "Building your own engine from scratch", where you ask the legends for some tips and show them, like engine wall thickness, the best materials, etc... There are no videos on youtube like these, I think it's a good idea! Again, thank you so much for the videos!
Thank you, Maju! I'm documenting the build of their new 5L V12. Takes a long time to get everything in play. The block is constructed and they are having it heat treated as we speak. the Rods, Pistons, and Cranks are ready to go. We will probably do a bottom-end build video then the top-end and full assembly, then initial start-up and run. thank you! Greg Q
920hp from a naturally aspirated V12 is pretty bloody awesome! 👍 People don't realise that having that many moving parts causes a lot of static friction between parts? The less moving parts the better in most cases? But I applaud the builders of this strange drag beast! Make sure they don't get too much flames out the exhaust or those straps holding it down will melt end launch this like Space X off the dyno!
Greg thankyou🙏 for these videos we'd have never seen Pete and Kevin's engineering Masterpieces if not for you making these videos and Pete and Kevin allowing you into their horsepower laboratory. The v12 looks violent💪 on the dyno and it sounds absolutely incredible😍 I can't wait to see some driving footage from El mirage.
Thank you, Greg. I'm real glad you're documenting this evolving story. Is it possible to get some details about the induction system? It looks like several things have changed since the original video you posted of running this engine.
The fuel induction system is the same, Pete and Kevin added 12 NOS nozzles above each throttle body for when they are ready to run it nitrous. For now it will run on gasoline until they set the Bonneville record.
Awesome build to be piloted by one of the most skilled and talented multi venue driver ever, my hats off to Cal Rothe a super nice guy and may the race gods be with him.
Wayne, Subscribe to the channel- there are a few videos explaining this 6L V12 - Pete and Kevin are currently building a 5L V12 as well. Thank you, Greg
Considering the new $3.5m+ Aston Martin Valkyrie makes 1001hp (at the crank) from 6.5l & everyone is raving about what a landmark engine Cosworth has built, it's refreshing to see a couple of geezers build a more powerful engine at 1/50th the cost with 50 fewer engineers.
@HowardJacobs thank you for appreciating Pete and Kevin’s talent and abilities. They are a crew of two and have successfully built over 100 Prototype engines and have a pretty good track record. They are not afraid to experiment and try new ideas. Most gear heads have an allegiance to one automotive brand, Ford, Chevy Mopar, Etc. Pete at 82 years old realized 40 years ago that many domestic iron built engines fall behind the curve with push rod engines and 2 valves. Pete has appreciation for 4 valve OHC and will admit Honda for example has superior head design than a LS. So in Pete’s mind, what would happen if you used Honda technology for example on a LS block? This is how they are successful and know how to make HP. Thank you!
Jay, I’m no pro at this UA-cam stuff, I just grab the GoPro and film. One of the videos I did over a year ago has 600k views. No production film crew here. This is 100% organic and no pre-scripted content. I just let Pete and Kevin work their magic and try my best to document it!
@@GregQuirin We all gotta start somewhere! This is amazing content that, with a little effort in commentary can get to the point of you guys getting sponsored. This is truly amazing work and deserves much more attention than it currently receives. This machine is insane you guys should be proud.
@@MrChevrolet94 Ferrari ran a similar capacity big V12 in their 612 Can Am car in the 1970s. Now I know there's been a lot of engine development since the 70s, but this engine appears to be producing quite a lot more power at higher rpm than those 6.2 L Ferrari engines.
BMW were getting more than 1200 hp with 4 cylinders and 1500 cc back in the 1980s. But just like the 427, they would be racing in a different class than this one.
Ahhhhh mate absolutely unreal! Happy for ya.. Have you considered connecting each exhaust bank together to see what it sounds like for pure "scientific reasons"??? I'm sure the sounds would be even more epic!
What is the architecture of the engine based on? Is it based on an OEM engine, or is it completely custom made? To hear a large displacement V12 engine have such a guttural noice all the way to the 10k redline instead of a high pitched scream is pleasant yet eeriely unnatural.
Some exhaust pulse collector tuning might be useful, to widen the powerband. After collecting it, the exhaust can be used to create artificial downforce, both push and pull.
the speed racers don't really need downforce. it's basically just about air resistance and power. (edit, obviously, they shouldn't take off the ground)
All four headers are collected in groups of three. Each group has a pulse ever 240 degrees. Which mix together with the collector from the other three cylinders on that bank which is also separated by 240 degrees between pulses making a pulse every 120 degrees. It is about as even as you can get without making an absolutely huge collector that would be an aerodynamic nightmare.
We started with for cylinder heads from Aurora engines they ran At Indianapolis around 2000. We cut one cylinder off each head and welded the heads into two six cylinder heads. We then fabricated a block from billet aluminum and aluminum box tubing. Had Scat build us a crankshaft and Darton make the sleeves and we machined the block.
@@kevinbraun6272 wow fantastic achievement. Did you use wet liners, or press them in to the crank case? May I ask what bore and stroke you used? Probably over square with these RPM’s?
Sounds amazing. I mean no offense or disrespect but why only 920hp? I'm seeing 1000-1100 out of high performance naturally aspirated 400-427" V8's. I can't imagine the engine is class limited.
You can get the same amount of horsepower and almost the same RPMs out of a 4-cylinder Honda engine but then it ends up costing just as much is that V12. The world's a messed up place
It's always something cool to see every single video you guys post!!! Amazing stuff, really!!!!!!
Thank you !

Honestly my favorite channel on UA-cam. Y'all are at the bleeding edge of backyard hot rodding.
Thank you for watching the channel we appreciate it!
We set a new record 5-20-2023 at 244.949 MPH with this engine. Old record was 228.060.

Dear God, that engine sings with the voice of angels! That was beautiful.
The sound this thing makes is why I also love the sound of a well tuned straight 6

Surprisingly narrow tyres considering the power of that V12.

I LIKE IT!!!
We made 910 hp on n.a. 427s on only 8 cylinders, at high rpm back in the early 90s.
Cummins diesels do it with 6
58 more cubic inches, 10 fewer horsepower.
My civic once made 1400hp without vtec and on 3 cilinders
BMW were getting more than 1200 hp with 4 cylinders and 1500 cc back in the 1980s. But just like the 427, they would be racing in a different class than this one.
@@alexjenner1108 But charged. 910hp Na is great.
But the bmw s88 had about 500 hp out of 3,5litre na. Wich is also great

Thank you! Rod
What is this engine based on? I see Gilmer belts driving the overhead cams....
bad ass
Good lord, would love to see the numbers, that thing was singing...
It's almost miraculous these guys can design and build engines like this from scratch. Who else does it?

Numbers? Peak RPM during pull?
920HP here is a video from last year on the Dyno ua-cam.com/video/yhLOl4rEi6E/v-deo.html
wow... 6 litres and 10000 rpms! insane!
What kind of class would something like that compete in?
hp / torque stats a secret ?
Baseline HP is 920. it was down a bit yesterday, Kevin is working on the tune. Back to the Dyno later today.
What is the architecture of the engine based on? Is it based on an OEM engine, or is it completely custom made?
To hear a large displacement V12 engine have such a guttural noice all the way to the 10k redline instead of a high pitched scream is pleasant yet eeriely unnatural.
since you've developed an extremely air volume efficient engine and it being able to handle those pressures, would you be willing to add turbo?
need full rebuild now
*WOW*
Get on a newer mainline hub dyno your problems on the dyno reading/tuning will be fixed. Great build good luck on the salt!
I wonder what the accurate number is. 1100?
How did you guys make the crank shaft?
High rpm music😊
Sounds even better in person! its an experience!
