    as a bmw tech. the new engine is no longer honed cylinderical (its tapered). they called it form honing, which greatly reduced thermal distrotion at tdc and already reduced friction at bdc. also the top rod bearing ,they use irox coating for msa stop and go, which supply lubrication when engine is stopped . its coated red.

    • @MMOchAForPrez

      Steph actually mentioned the start/stop rod bearing coating before in his B58 VS 2JZ video, if I remember correctly. He said they were not thrilled with the reliability at the power levels and rotating speeds they run around the track, so he switched to a rod bearing without the coating. Pretty interesting stuff

      Different requirements, it's the same difference as with the Vandervell vp2 brg. and something like Glacier tin alloy. Especially if they are running on a tuftrided or Nitrided crank. The Glacier will ultimately take more load, where as the Vandervell will take more damage and tolerate contamination to a far greater degree

    I've been watching Formula Drift and other drift leagues for years, and Papadakis is pretty much the highest standard around the world for engine builders in drifting. Rarely do you ever hear of mechanical engine isssues with their built cars. After watching this video, it's clear why that is with how meticulous the engine building process is.

      Toyota had a lot of influence. The Supra's chief engineer explained how they took the B58 apart and studied every part of it and they would send parts back to Japan for further analysis. Toyota's partnership with BMW pre-dates the creation of the B58.

    The break in oil question and his reaction were fantastic!
    Do remember he is going to have spare engines sitting ready to go. They don’t have time to break it in after rushing to put one in. Fill it full of fluids, and treat it how it’s going to be and he’s trusting it will be right and ready out of the gate. Both cars on his team are running this engine now so it’s been proven as much as it can but all of the big teams are like this.

    A proper engine build. Love seeing Davin and Stephan nerding out. Couple of questions: In the same engine family of the B58 you have the more sports oriented S58. Why is the S58 not used for this application? Also Toyota has a very sturdy 3.5 V6 on the shelf. Why is that one not selected? Also surprising to see a manual gearbox in a drift car. Makes it a long drivetrain for a initial FWD car, makes lovely inline 6 noise though. Keep up the good work.

    • @rsjet
      @rsjet 6 หลายเดือนก่อน +2

      B58 because it's still a Toyota product (since it's used in the Supra) while S58 is not. For your second question, I'm guessing either the Toyota V6 can't make that much power reliably and/or size constraints.

      @Lucas-ck1po 6 หลายเดือนก่อน +8

      The S58 engine is an M division sports car engine with much lower availability and significantly higher cost compared to the B58.
      The question isn't "why not S58", instead "why anything else other than B58".
      The thing is, the B58 is an engine BMW engineered to propel a significant portion of their product line-up. The B58 is used in X4, X3, M440, M140i, M240i, 340, X5, X6, X7, 540i, 740i, Supra, Z4... This engine was engineered with the purpose of receiving different pistons, compressions, turbine sizes and cams according to the application since it goes in manual Supras and also goes to hybridized powertrains focused in comfort and efficiency inside large, heavy SUVs. So, production reduces costs.
      The second thing is that BMW engineered this engine with alot of headroom since its supposed to endure the most varied of applications, and this is all these people need.
      They are going to strip alot from these engines and use their own programable ECUs, own cams, own turbochargers, intake manifolds, exhaust manifolds, injectors, pistons, con-rods, transmissions, pumps, coolers, intercoolers etc
      All they need is a beefy block, tough cylinder head that gives flow with little modifications, enough bearing area to keep up with the pressure and thats it, all else they will source/develop themselves.
      Many expensive qualities and goodies from an S58 would be striped away because they wouldn't fit such application anyways.

    • @jimmyaber5920
      @jimmyaber5920 6 หลายเดือนก่อน +1

      The shells are oil distributors and the miniscule difference in std and plus or minus increment shells is so slight. There are many engines manufactured with selective fit mains. The old way was to make accepted clearance wider to reduce scrapping loose spec parts. With size range shells you can make up for blocks with honed bearing openings and crank journals that needed more polish finish to get acceptable journal dimensional quality. The selective shells allows the oil clearance to be optimal and not throw away blocks and cranks. Most main bearing fails wreck the crank and block and the extra work selecting bearings from a more expensive bearing kit is very rare, a new engine is installed.

    For a factory block, they have to pick a compromise. I don't think you can have a perfect mass produced engine. You'll have variation in production and hence you'll see some engines that put out different Dyno numbers than others.
    Also when a factory engine is assembled, you aren't checking every single clearance 10 times. You assemble everything and turn it. If it doesn't bind, send it.
    Direct injection plus port injection imho would be the best bet. Probably the tuner wants to cool the cylinder charge with fuel however this also slowly kills the engine, is less efficient and gasoline is a poor conductor of heat. Water meth injection works much better for cooling and is a fuel as well.

    I'd take a guess that with the FEA they've run, the taper is probably due to the way the thermal properties (ie. distribution of temps) are around the block at operating temps (ie. top/bottom may run hotter/cooler than the alternative end due to things like the coolant/oil gallery design or even thermal mass of the block). As a result, there's probably a transition in terms of how much the bore expands across it's distance/length, so they're likely just accounting for that transition... ie. the tapered machining may result in the bores actually being pretty uniform/round at operating temps, across the length of the bore (TDC to BDC).

    What product was he dabbing on the head nuts before he torqued them down? White bottle with blue label?
    Subbed and belled!

      I looked it up and the bottle seems to match ARP assembly lube.

      In the video, he said he uses the CP Carillo assembly lube because it has given him better results than the ARP assembly lube
