  1. Also something to note, as you widen a runner it is possible to reduce the overall flow due to the resulting bends. Larger diameter pipes end up having sharper bends in a direction change over the same distance. Just something to keep in mind. Also going too big can have negative effects in other ways, like reducing exhaust speed.

  2. I was thinking you also replaced the internals and I would have said this was actually a little disappointing. But with carbs and power (~134 hp) and torque (~112 lb-ft ) being around the same, that's pretty good for an intake and cams.

  3. I am glad you made a video on this very few people discuss it.

  4. Even more powerful than the Zeod DIG-T?

  5. *This comment somehow posted on 2 videos. YouTube sometimes... Anyway, regardless of fandom, people who aren't willing to accept flaws or see other perspectives are a nuisance at times.

  8. It depends on what you mean by "big power" 1000-2000hp that just isn't realistically streetable anyway... No 700hp... Yes. But I agree that swapping to the right engine it is a better value. Because why spend $30,000 rebuilding an old engine, when you could buy a new engine for $700 and add be ahead of where you would be with $6,000 of mods. Or apply some forced induction and get those absurd numbers.

  9. I am surprised force/efficiency wasn't discussed that much. Also that despite the close relation to compression ratio it was not noted throughout.

  10. I could have save a lot of time a few years ago rather than working through all of this myself. Just by looking at different firing orders.

  12. ...Ah, I see the parallel.

  13. This would not be an issue on your engine if Toyota didn't do the dumb thing and wrap the exhaust around the engine. More heat in the engine bay, warmer intake air temp, easier to burn yourselt, more weight/material, less access to the underside of the engine...

  14. Q8 may be a surprise to some engineers but that's pretty basic for business/entrepreneurship. Prove the concept, start with one focus, but have others planned, establish reliable sales, and expand as you hit those milestones. Quite frankly it's a component of a business plan. If companies are getting investment without a logical approach, send the money to me because I can come up with ideas with no plan too.

  15. I swear this was debunked years ago (I guess it takes a long time to correct misconceptions). The average (not bad) car today gets 300,000 to 400,000 kms. A bad car would get at least 100,000. A very reliable car will get over 400,000 km. That did not used to be the case, and there will always be lemons. That said, the reliable cars of yesterday may not be as reliable today. Especially Toyotas.

  16. Yeah it cut the weird sharp tones. That said... If there were a resonator then a straight through it might be better?

  17. Awww, I thought you were pulling the whole thing apart. :(

  19. So... Would the balance be better with a crossplane crank? Like that one Yamaha engine had?

  20. ...So are you saying if we make it out of carbon Buckyball that will work better?

  21. Yes, patents are good but then the information becomes public. Best to patent key components and keep things a secret for as long as possible. Because once it is patented it's public and all someone needs to do is change it just enough then run with it. But if you launch your product first they then have to overcome the barrier of an established competitor

  22. *always bolted onto the cylinder head... unless it is part of the cylinder head. But a relatively infrequent exception.

  23. I have to disagree that newer engines being more powerful and efficient mean they are less durable. Often efficiency improves durability. But on many, there is the issue of saving money by triming every bit of excess.they can get rid of. Subsequently reducing the margin of safety, often to the point where the stock output is near the limit of the drivetrain.

  24. I mean, there are people who like loud supercharger whine and can't even hear the exaust, it'd probably be a lot like that.

  25. The sexiest word is whatever you wish your girlfriend was whispering to you if she wasn't too busy wispering silly and unsexy things because she finds it hilarious. (I do too, but don't tell her I said that).

  26. I consider a log a roller. But in terms of classification that would then make wheels a subclass of roller.

  27. Shouldn't those force waves broaden and pinch depending on TDC of BDC?

  33. I get that the GE design would be advantageous if you had variable cam phasing, but in terms of adjustability it is merely an advantage in terms of convenience as you can alter the cam phase (with more coarse adjustment) on the FE as well...

  34. Wouldn't a bang/backfire be an actual detonation outside of the combustion chamber, where as a crackle would be something like an exhaust valve opening too early and the combustion continuing out into the manifold?

  35. He is avoiding discussion of hybrids which would be a lighter weight high performance solution (compared to full electric).

  36. I want to see a race between a track ready 1991 442 and a E30 M3 Evo1. They would be about the same weight, if the 442 were track prepped. Both, 2.3L Inline-4s with similar output. (S14 having the advantage, unless the W41 was slightly modified). They weren't at all competitors, but they're both unique in their own way. Moreover, a race between them would be equally unique and cool to see how the differnt approaches would compare on the track.
