    I’ll say this is very cool a little v8. Wow the engineering of that is very cool. My car is 3.3l 8150rpm in-line 6. Damn this little baby puts out serious power per cubic inch. Top notch work here. It’s mental. And people may think that 40 hours warranty. That’s amazing for a race engine. I worked in NASCAR for over 8 years and we generally rebuilt the engines every race. Same deal as this gem. Basically rings and bearings and check everything for wear and look for failure of any components. Sometimes we ran 2 races on one but very rarely. So basically 5-600 race miles they were refreshed, warranty for 1500 miles or 40 hours. That’s some serious durability for a high strung race engine. Hats 🎩 off to your skill. The NASCAR engines were basically freshened up every about after 12 hours. That’s about all the time is on one after dynoing practice and race. The races are usually over in 3 hours. If we had a wreck or something else that put us out early we would run that engine the next week. WOW 🤩!!!!!!!!!! I have watched this twice so I didn’t miss anything.

      @identiticrisis Год назад +1

      @@MrSuchasillygoose it's a completely different class of engine and machine. It's even explained in the video, they already knew Hayabusa engines and so when the requests for more power kept coming in, they simply doubled up the Busa heads and tied them together at the bottom. Clearly turbo wasn't an option for them, likely on grounds of reliability and heat. Of course any engine that can withstand sustained high rpm operation cannot be termed fragile, those forces scale as to the square of engine speed - motorcycle engines are very tough in their own way. Granted, if you couple a motorcycle engine with a car chassis, you're likely to destroy the transmission, clutch and primary drive (maybe even the crank and cam drive) in short order due to the massive difference in inertial forces through the drivetrain. Luckily a Radical is incredibly light by design and has small lightweight wheels etc. The driving experience offered by keeping the Busa basis is completely different, and I'll wager Radical's customers appreciate that.

    • @MrSuchasillygoose
      @MrSuchasillygoose Год назад

      @@identiticrisis It's more exotic, I give you that, and if the pockets are deep enough then a good option. There is a guy with a quarter NASCAR busa build that comes to track and blows the transmission every time. The Radical guys do not drive to the pump because it puts on hours on the engine, that's fragile in my book. Some spend 3 laps just getting the oil temp high enough so they can unlock the revs. The Radical may be light and has small wheels but it's still a two person car, the compound is soft, and has real aero. The loads on the engine at high speed are quite high. Motorcycle aero can't compare to something like a prototype, which Radical arguably is. I'm going through this with the Atom, steel tube frame, 300m axles, PPG trans, and Gear X trans all failing from aero loading. But the one thing that holds is the 500hp Honda block. It's nice to have something robust in the build.

    A friend and I talked at length about making an engine like this, however we were looking to use the Honda 1000cc V twin from the firestorm. So essentially a 4L V8 revving to about 12,000rpm using Honda internals. Wanted to fit it to a S2000 and call it a S4000. But then we got realistic, looked at costs of making the block etc and scrapped the idea. I just wish you guys had one in a car that was running so we could hear it.

    These guys aren’t the first to build a hayabusa v8. Neil Gray from NZ, designed and built one of these 15 ish years ago, created a car to go around the engine, not sure if this is the result of his work or not. There was an article in the “Wheels” magazine early 2000s on him and the whole kit and caboodle❤

    I would have loved to hear how they mitigated friction from the larger conrod journals. I WISH this was more technical, to say I'm disappointed is an understatement. The rpe/hartley/synergy motors are some of my favorite designs and he basically just stated what was in the rpe brochures. His description of the balance was painful, you were really prying to get him to elaborate lol. I'm sure you know this I'll state it for those that don't, the cross plane requires huge counter weights to negate the primary force imbalances. However the flat plane has secondary moment imbalances from the unbalanced piston accelerations. For a 90 degree v8 it would only be about 41% more than a stock Busa w/o balance shafts but because it's 72 degrees it's a bit more, like around 50% of course they could run balance shafts to negate this but its a race car so radical doesn't really care about the NHV and would rather lose the weight, inertia, complexity and cost.
    For those interested in dynamic reciprocating engine balance, I haven't found any good videos that describe the topic very well, engineering explained is the best of the worst. Only places that have done a good job is bosch's automotive handbook or better yet advanced engine technology by heinz heisler.

      But 40 hours for a race engine isn't bad, especially if you can just do rings and bearings and be back at it.
      I think the biggest problem with this design is the bank angle. Should have stuck with the 90* bank angle for balance, would have let them run lighter parts and therefore rev higher.

    This is a super cool engine I have been curious about for a few years so thanks for doing an episode on it. A few questions. Why use alloy cylinder sleeves instead of steel like a LS? Why not use Alloy rods at that RPM and power level? It would run with less vibration and lower rotating mass. Also whats the cam and valve set up? They should make the Crankcase out of billet and steel sleeve it so it could run with power adders and then sell it as a crate engine.

    • @CP110
      @CP110 5 лет назад +1

      Alloy rods need significantly more material so in a tight 72 degree bank its possible that it would run into something, also the rod would never last ass long a steel or titanium one, as far as sleeves go thats mainly due to weight and rigidity. as far as cam info just look up stock hayabusa cylinder heads

    • @tazgrant4521
      @tazgrant4521 5 лет назад +1

      The sleeves have a friction reducing coating and the rings are 1mm steel that have a PVD coating also. With sleeve and piston made of similar material because expansion is the same amounts it can be less clearances of piston to bore. With liners made from steel it expansion rate is different so aluminium pistons need bigger clearances. The heads on gen2 Busa have titanium valves and under 9mm lift from camshafts. Valve train is very lightweight.
