I know Vegas are mostly not awesome, but this one is awesome:    Pics from Hot Wheels' Instagram - it was at and one one of the Legends Tour events. A short build article from before it was finished: https://www.chevyhardcore.com/news/build-spotlight-imsa-inspired-vega/ That's a nice ride. I kind of wish I still had my '78 Monza Spyder so I could do something similar.

Intake stacks/bellmouths help increase volumetric efficiency in a small RPM range. They work regardless of the fuel delivery method.

BMW probably has some nice paperwork on it for the S54, S62, S65, S85, etc motors. Or one of any motorcycle manufacturers. Yamaha / Mazda / others also had ITBs with variable length velocity stacks. BlackMK4 fucked around with this message at 06:45 on Oct 4, 2019 |

I don't see what fuel delivery has to do with it - ITBs like that are all about maximum airflow / throttle response / glorious intake noises. It'd be a bit of a pain to tune since you can't really run a MAF and I think even speed density might be painful when trying to sense pressure in individual runners like that, but clearly there's a solution for it since these setups do exist.

People have had issues getting the ITB S2000s running right since a lot of the older, affordable standalone ECUs were based on speed density or alpha-n. Seems like a lot of the newer uh prosumer? level ECUs work off VE to targeted AFR, which appears to be a lot easier to deal with.

They're water cooled and probably don't run much hotter than consumer engines. F1 cars are fast because they're light and small.

I'm just thinking of things I've heard about not driving them fast enough to get heat in the tires (probably not an issue poking about on the highway) and having to have warm coolant cycled through them before the engine is started (yeah, sure, but an engine at 75 F vs an engine at 170F is different than an engine at 170F vs an engine at 220F).

The latter is true, modernish F1 engines are pretty much seized when cold. Highway speeds are probably the slowest the car can go indefinitely, though. I would bet that at lower speeds not enough air actually gets through the sidepods.

At the risk of starting a derail, how often do the engine spec rules change in F1 and what are the current specs? They're all technically hybrid powerplants now, aren't they?

Mister Speaker posted:At the risk of starting a derail, how often do the engine spec rules change in F1 and what are the current specs? They're all technically hybrid powerplants now, aren't they? Short version... Around 7 years. Current spec is a turbo v6 1.6L that has heat/energy recovery systems. Something different will appear in 2021. The constructors can replace so many parts as a way to make them save costs (haha) before getting grid penalties. Nearly everyone wants the V10 (or 12) back just for the noise, but I do find it amazing that these engines last around 4-5 races each and hit around 45% fuel efficiency. As for the racing, last 4 or 5 have actually been drat good for a change. Usually though yeah, it is a parade, so pick a driver you like and see how he battles in mid-pack. edit: On last thing is the big change will be aero. It has gotten so out of hand (and if you see their front wings you will understand why). Trying to promote cleaner air for better passing.

The problem with F1 is the races are won in qualifying and MotoGP is slowly turning into the same thing. The technology available to make a faster racecar/bike has outrun the teams' bankroll to implement it so everything is being homogenized by rules to try and keep the number of vehicles on the track up.

Yeah, with F1 qualifying and turn 1 at the race sums up 99% of the excitement. Sad to see if MotoGP going that way.
