A lot of things you do on race cars trade convenience for performance.  Sometimes those things even include being able to idle for extended periods of time.

Even with an internal oil leak, you’d still need the throttle butterfly to fail.  On an engine moving that much air, it’s entirely possible that the butterfly just snapped when activated.

A lot of the service intervals are based on calendar dates as well as odometer readings. Wouldn’t surprise me if the oil change interval was annual or 3000 miles, whichever comes first.

For that matter, I have two vehicles in my driveway who get annual oil changes, even though they’ve yet to hit 3000 miles in one year.

I don’t believe any details have been released, but the rumors I’m hearing is that it was basically a flow conditioner. It didn’t increase the size of the regulatory restrictor plate (in fact it may have actually reduced it further), but it made the fuel flow smoother through it, which effectively increased the net…

They have machines now which basically just recycle the paper, same as gets done to the recycled paper you buy in a store.

All the track needs is one spot each lap where cars can pass. The obvious place is the Neuvelle Chicane, but the trouble is that the straight leading onto it just isn’t really long enough to get alongside, especially when the leading car can push you offline in the tunnel.

My solution then is to just alter (extend) the…

Would there be though? I thought one of the differences with NASCAR was that they didn’t allow data loggers, so their only source of “data” was from the nut behind the wheel - or is something that’s changed with their recent move to “modernize” in the last few years?

I support your theory, but I was thinking more fuel injection = no wooden wheel

They banned the upper portion of the “loophole box”, but the lower portion is still very much available. It’s not as effective, so not all the teams are using it though.

This is not the first time they’ve made this mistake.

The T-Wings in 2017? Yeah, they were caused by a similar “move box x without modifying restriction y” oversight in the rules.

A night race wouldn’t happen in North America. The night races they have all are done to optimize tv viewing times in Europe. Moving a race in EST to run at night would have the opposite effect.

It’s been covered here before - CAFE favors bigger cars. If you can make your car physically larger, yet keep the same MPG’s, you’ll do a lot better than dropping the MPG’s of an existing platform.

If you knew what you knew now in 2016, you’d have been much better off spending that money in bitcoin, and then dumping it around January 2018.

Where are you getting the 25% efficiency figure? My understanding is that the current gen of F1 engines are somewhere in the neighborhood of 55-60% efficiency.

You can see an example of it here:

As someone who has driven many a race car with a CVT transmission (including the one in my profile picture), I have to say a CVT can be very fun and very fast.

The *problem* with CVT’s in most cars (namely Nissan’s) is that they are much more tunable electronically, and many of the cars out there have their CVT’s…

If what was said earlier is true - that it’s only available for cars with less than 500km on them, my guess it was really just as simple as satisfying the “new money” rich brats who demand that their Ferrari have “0 miles” on the odometer when they buy it.

There’s literally hundreds of motor options out there, but this is roughly inline with the hp rating of a KZ2 kart, which is what most people mean when they say “Shifter Kart”. For instance my KZ2 motor supposedly makes ~48hp if you believe the manufacturer’s marketing materials (I’ve never dyno’d to verify).

That…

I get the reference, but you’re more accurate than you probably realize. A lot of the guys would much rather drive 2 or 3 F350's with 4 car trailers in tow (all likely overloaded and with overtired drivers), than to run class 8 trucks, just so they can avoid CDL restrictions.

As with any used car dealership, there’s good ones and bad ones, but more than one has been caught selling flood cars.
