    I am aware of that. You are correct about the fillets and the like. However, the material quality (strength of material) in casting is still not as strong as the other methods. However, as you...

    True, I should have also added my other point, it used to be the only compelling argument for a diesel was mileage. They were smelly, noisy etc. Well now they aren’t smelly, noisy etc but they also...

    I don't buy these arguments. Basically the claim is we got a bunch of crappy diesel cars almost 30 years ago so we won't buy them now. No. A huge segment of the driving population wasn't driving...

    OK :)
    I haven't been following the whole thing. It's sometimes hard to tell who takes things like Hp/L seriously vs who take it in context. Keep on trucking ;)

    The Ford vs Merc comparison isn't valid because the two products are designed to meet MUCH different goals. The Ford engine is a work truck motor. It's designed to provide low end power, be used to...

    The late 80s turbos were quite impressive though at least part of their very high HP/L was due to the very volatile fuel they used. Those engines would not have produced as much power on the fuel...

    I seriously doubt the 70K hp claim. RR-Alison and Honeywell launched a new helicopter engine in the late 90s. It had about 800hp and weighted about 400lb. Future versions of that motor were...

    As I recall from my time at Rolls Royce-Alison their compression ratio was more like 9:1. The pressure in the combustion chamber is very low compared to a piston motor. Also, in automotive sized...

    That generalization is true but that larger engine will also produce more power at the same revs as the smaller engine (again a generalization). So if we want the same power from a smaller motor it...

    Not quite a built but they are slowly becoming more popular. Some people claim it's because we had bad experience with diesel cars in the late 70s and early 80s. I don't buy that. Too many people...

    I haven't driven many diesels (I can't say I've ever driven a diesel car) but I've always heard that. A very appropriate power curve for most driving.

    Interestingly the reason Honda went to 2.2L in the US was because of market research. They found S2000 buyers were almost always happy with the 2L motor. But when they asked people who didn't buy...

    Both engines were rated at 240hp using the old Honda system. Only the 2.2L was retested using the new system. It seems likely that both engines would drop a similar amount given that they weren’t...

    It's unlikely the original S2000 motor was producing an honest 120hp/L. Honda re-rated the 2.2L version of the S2000 a year or two ago because the old method they had been using to measure power was...

    For on road use you need a center differential because the front and rear axles don't always spin at the same speed. For off road use this isn't as important because you are going slow and you just...
