NASCAR Truck engies on a road course

[tjs44]

I just watched a Ford Truck in Qualifying today turn 10200 and 10400 in Q laps,does that seem normal on a road course like COTA?I know their Yates engine but WOW.Tom

The pole sitter is doing 8700rpm:


Also, the tv tach seems out of sync or it’s made up? The throttle / brake you see on a lot of tv feeds are just guesses based on gps. No one is publicly broadcasting that info. Even the F1 tv / data stuff you see is only publicly at 3.7Hz.

The straight at COTA is stupid long. The MotoGP bikes are seeing 221mph there.

Do you think Yates might be turning up the Fords that much more than the Chevy?Tom

Not at all. The aero, engines, gear ratios, etc. are all pretty much spec and the differences between them all is hundredths of a percent in performance, and mostly related to set up / driver talent.

Pretty sure the Trucks are all spec engines too.

The truck engines are all LS based built by Ilmor.

[swampbuggy]

Warpspeed, are you saying that the Trucks representing Ford and Toyota are LS based Engines ?? The Only reason i ask is because you used the word
" All " . Mark H.

[Warp Speed]

Yes. All the engine's used in the truck series, regardless of manufacturer, are LS engines.

Thank you sir, but that really is surprising to me. Seems like an IROC in the Craftsman Truck Series ?

It’s a driver development series, IMO, it should be mostly spec.

Why should the series be mostly spec ? What is the reason behind that thought process ??

It’s a cost controlled series which has turned into a driver development series. It bridges the gap from ARCA to the faster cars.

If you want to keep a pipeline of drivers, you need to make it so more people can afford it, and then make it spec so they can focus on racing skills and showcase talent.

The alternative is something like F1, where their feeder series are mostly spec, but you end up with sons of billionaires making it because they can just outspend everyone else. A few got through on talent, and being picked up early on by a factory (so billion dollar corporation instead of dad).

Lots of kids in both open wheel, oval, and motorcycle racing have to borrow money from “investors” that they have to pay back when they hopefully become big (or share a cut of it). Controlling costs helps limit how much they’re in other people’s pockets.

You open the rules up, 2/3 of the field closes up shop, and only the richest win.

[tjs44]

I knew they were a spec engine but thought they could still run their own make engines.Tom

Wow 10,000 you would think that would twist the rear end out of the truck.

In 2004 the cup engines were turning 10k plus. I was doing the Arca deal with a then 17 year old Kyle Busch. We had a flat tappet Cup engine in the car doing development for the Cup series. We raced Pocono with a 4.33 gear and a .91 overdrive turning 10,400 in every gear. That is until we got taken out near the end, on a restart by a field filler! Lol
That was pretty much the end of an era, as Nascar implemented a gear rule shortly there after.
The RPM flashes you seen in the truck deal were mainly from the poorer quality telemetry vs Cup, and the many obstacles (overhead bridges ect) at the Cota track interrupting the signal.

BTW, anyone see the end of the Xfinity race?!?
