Apparently the hotness for first-gen cars is to swap the 2ZZ-GE from, of all things, a Toyota Matrix XRS. At 180 HP and 8200 RPM, it’s a really good match for the car. Better than the 145 HP 4A-GZE.

They grew because of the way vehicle footprint factors into CAFE requirements. The only way to meet standards with a tiny truck would be an economy-car drivetrain and structure, and only six people would buy them.

I’m pretty sure in one video he admitted to holding a doctorate and working in or around the mining industry. He may talk funny, but he definitely knows his shit. And, refreshingly, he’s willing to learn from his commenters and admit mistakes when relevant.

Obviously, there will be compromises. Minimizing them, I see three options:

How do you figure? Generally, the “P” in CFRP refers to the matrix material - whether it’s epoxy or polyester, it’s a plastic. You can make a non-plastic matrix, but then it’s something like CFRC (carbon-carbon).

Inbox is great on mobile devices. The interface is tidy and the organization and built-in shortcuts are great for quickly getting through messages.

It really surprises me more people don’t swap LS engines into BMWs.

I totally understand all the people complaining that this over-complicates things, and why aren’t mirrors good enough, and I can adjust my mirrors just fine.

Whoa, who said anything about 1200 RPM? That’s plain abusive to the car and you’re right, nobody should drive stick that way.

“People don’t drive sticks that way.”

You must have driven better 4-speeds or worse 6-speeds than I have. I’ve found hunting and gear selection way worse in the 4, when I need just a bit more power on a long grade and it decides I need to be at 4000 RPM for the next couple miles.

I think with 6-7 gear transmissions we had gotten to the point where the gear spacing was pretty good, but with the increasing numbers lately they’re not just shoehorning more gears into the same range. They’re adding extra overdrives so you can cruise a flat highway at 1200 RPM and can ascend a slight grade in a…

This is interesting information, but I really hope nobody latches on and tries to lower speed limits.

“Engine failure review” or not, I again say that air is air. You need the same amount of it to produce a given amount of horsepower no matter how the engine is configured, and moving that quantity of air in a particular timeframe implies a particular volumetric flow rate.

Air is air. Turbos don’t suck any more of it than a bigger NA engine making the same horsepower, and I find it unlikely they suck any additional sand along with that air.

I really hope you’re wrong, and Koenigsegg is NOT a decade ahead of everyone else. The Regera is the first supercar/hypercar I’ve had the slightest interest in since I graduated from high school and realized I wasn’t ever going to own something like that. I hope Ford has a secret prototype in a basement shop…

Cams aren’t free, either. There’s quite a lot of friction involved in whirling those parts around. That’s not to say FreeValve is MORE efficient, but it might turn out to be a situation like CVTs; they have higher frictional losses and are less efficient than gears at any particular ratio, but the other efficiency…

Tire Rack already has the RS listed and won’t give you any options smaller than 19". I’m guessing 18" is really the smallest you can fit over those brakes.

I wonder if this is sort of the more mundane, low-cost approach to a setup like Koenigsegg uses in the Regera. At low speed you’re depending more on the electrics and the engine might even be disconnected and only running a generator. But without the Regera’s 950 ft-lb from the engine, a single gear could be…

From the numbers I’ve seen, the cars still meet emissions standards from ~2006, and in any case we didn’t test NOx prior to 2000. If that’s accurate and I’m not misreading the standards, it’s not like VW is out fumigating the streets and bringing back 1970's levels of smog and acid rain.
