I thought this video was really neat. I get that itís a marketing video but I never knew this is how the oil system in this type of car worked. Kinda cool. Video gets good at about 1:00 min in

No wonder those races are so noisy. j/k.

Very cool, nonetheless; thanks.

You would think a high performance Toyota V8 would have roller lifters.

Reminds me of the old RP ads. Saying that if you use their oil,you'll go faster,have more horsepower,etc.

Thats not a Toyota V8, not even close.
All NASCAR engines are the same basic design, no matter who the sponsor is. Makes the races closer and hence more exciting. Rules say its the same older design style pushrod V8.

They are all architecturally similar. Ford's is based on the SBF IIRC, because you could buy Winston cup heads and put them on your SBF, though I think matching an intake to it was a chore. GM I believe uses something based on the LSx?

Toyota of course didn't have a pushrod V8 so they just kinda "made one".

Well unless things have changed, NASCAR does not allow the use of roller lifters in competition.

Interesting video, but has some issues.

1) They use stupid statements like "the oil pump puts out over twice the pressure that you would find in the race tires" ... huh? Why not just say at what PSI the oil pump operates at.

2) When talking about the load in the rod big end bearings, why not just say 76,500 PSI instead of "5000 times more than atmospheric pressure"? I'm surprised they didn't work in a "fortnight" in there somewhere.

3) They said the oil filter is catches 95% of all particles below 10 microns. I find that on hard to believe, and think they actually meant all particles above 10 microns.

4) They said the entire oil system circulated once every 8 seconds. Earlier they said the system held 5 gallons and the oil pump was running at 12 GPM. With those parameters, 5 gallons would circulate once every 25 seconds.

The only thing "Toyota" on those cars is the Toyota emblem.

Thanks for posting, I'd always wondered how a dry sump worked.

What caught my eye was the asymmetrical exhaust port spacing like a 1st generation small block Chev. Not likely. But the basic explanation of the NASCAR oiling system was quite informative. Other than some errors in the details, an excellent video.

Dry sumps work by over savaging. They are capable of pumping out more than the system puts in ... I don't recall, but those engines may be operating at less than atmospheric ... I seem to recall a vacuum pump on that aux string somewhere ...

The companies can buy all sorts of aftermarket blocks and heads that will pattern up to NASCAR specs. You could build a NASCAR legal engine w/o a single OEM part unless they are spec'ing OEM part numbers (they used too ...).

99.9% or street engines do not have oil squirters cooling the pistons. Trucks, yes. Cars, no ...

It makes baby Jesus cry when a big company like Mobil puts out poorly done technical videos like this.

Ford Coyote and Voodoo engines have oil squirters.
