RE: nascar engines
just concider in the 80's the cars were running over 220......it takes a great valve train to run 8500+ for hours and the heat cycles on the engine is admazing..this is why they use sodium filled valve and there thermo coated......it they incorp.. the new spring coming out you will see 9K= rpms all day long..if they could put a 1050 like yester year.... speeds would be off the charts.........there is a fine line to where the engine will like rattle apart

They could get more power within the rules, but it's just pushing it too much. If they could use whatever parts they wanted in their 357, I'm sure they could get well over the 900hp mark.
Crazy thing is, they are now turning over 10,000 rpms on some tracks... [&:]

They were turning 10,000 at Daytona this year.

There's a difference between lasting 500 miles and redlining it for 500 miles, 4 hours.
4 hours of full throttle run! Nascars average 10 s in the 1/4 mile, so 4 hours full throttle is the equaivalent of: 3600s / 10 * 4 = 1440 1/4 mile passes!
Now imagine a engine making 1440 passes, sounds even more impressive now?
It's easy to make a crazy engine that cruises at 2000 rpm for 500 miles, but that's not what nascar engines do.

They only have to last one race. I'm sure you could get allot more power out of you engine if you only wanted it to last for 500 miles.

Actually the 1/4 varies on which track the car is set-up for... Car and Driver tested out one of Mayfield's cars liek they do production cars, just for fun, and it ran about 13.8s... they also completely destroyed 3 or so clutches trying to dump it on launches.

RE: nascar engines
With only 4 gears to play with and a 200+ mph top speeds, most setups would be crappy for acceleration. In the June 2000 issue of R&T, they had a properly setup Nascar for the 1/4 mile and it went into the 9's trapping over 160.
With a superspeedway gearing, you'd have to slip the clutch all the way to 60 mph or so. But try a roll-on with a Nascar if you're less than 900 hp you'll get destroyed.

I think Formula1 engines are amazing. They have like 3 liter v10s. They Idle at 8000rpm and have like 18000rpm redline

RE: nascar engines
they dont cost $1,000,000++ for nothing
the suspensions in them are also what aid their high speeds and corner carving capabilities.
a nascar on the street would just apsolutely dominate anything except maybe a haybusa? who knows!
