Thread: Is This (at least a little bit) Disturbing?

  1. #61
    I doubt the Corvette motor would last 500 miles at full chat.
    All rides are bought. But occasionally the currency is talent.

    It's a great looking car, but it looks like they just stuck some 500 stickers on the 60th anniversary Corvertte.

    If they used the Corvettte at Daytona it would not even have to pull in on the pace lap. It could just floor it and drive away from the pack.

    Add in the downforce, suspension, level of grip, etc of the DW12 over the ZR1, plus toss in professional drivers over Joe Shmoe with $115k cash walking in off the street to buy a ZR1. I'll take the DW12 in a fight on the track.
    Yeah, sure. But it used to be that the pace car looked like a scared rabbit with 33 hungry wolves behind it and now it is getting close to even. What is disturbing is that street car technology has gone forward while Indycar technology has gone backward. They need to figure out how to go faster more safely- or rather, they need to figure out how to make a profit so they can fix things.

    I wonder how close that corvette could get to qualifying. Could it do a 170mph lap I wonder.

    Oh, I'm not so sure about that. In any case IndyCar would have to detune it by 88 horsepower to equalize it with the current race motors.. It wouldn't be anywhere near full chat. More like a mumble.

    Uhh no. The corvette would be dog slow in comparison, way more weight and terrible aero.

    F1 had qualifying motors at 1400+hp at 1.5L in the 1980's, the best of which are made by a current indycar supplier. I really don't see what the big deal is about pure hp numbers, 600hp out of a 6L supercharged engine is not impressive production or not IMO.

    I did a 156 MPH lap on Forza. The car is evil. I'd be interested to see what anyone else could get out of it.

    It is when you consider how long the engine is designed to run with very little maintenance and that it makes 638 hp on pump gas while saddled with smog equipment that helps it to run very cleanly.

    It did just fine with GM's durability tests, which included running it for 24 straight hours,
    The ZR1 is undergoing GM's full battery of passenger-car durability tests as well as its motorsport torture regimen (250 miles of autocrossing and a 24-hour endurance race), so it should hold up fine.

    Plus it could do the 500 with just 1 stop for fuel and no tires.

    Have you ever seen an engine/tranny test cell? They strap those puppies in and run them around the clock to simulate road conditions such as traffic, uphills, downhills, cross country, etc. It really is impressive to see how they test those components. Really cool stuff. I'm always amazed when I see that stuff running.

    I want to know how the current DP Vette is going to translate to the next generation of Vette? That was a seriously impressive butt kicking they did at Barber. That car was in a class all its own. I was shaking my head each time it went past.




    Side note: I have a good buddy that has a retired World Challenge C5 Z06 that I help crew when he tracks it. What a fun car to be in on a track!

    But consider that its characteristics might much better separate the sheep from the wolves in the chauffeur dept.
    It appears our new high downforce low power Indycar will run flatout laps at 218 +/- 2 mph.

    I wouldn't mind the HP of the new engines if they'd cut the downforce in half. Other OW series do just fine with 500 HP, with cars pushing the edge of adhesion as drivers dice.

    I don't see that in these IndyCars. Maybe next year with the newer aero kits. Hopefully less will be more.

    So you're hoping that next year's aero kits will make less downforce?

    Seems unlikely.

    Legge might have a better chance of Qualifying using a Corvette .

    Umm, yeah. 6l supercharged engine ought to be able to put out 2,000 to 3,000 hp as long as you are williing to rebuild it every 3 to 4 seconds.

    TRANSVERSE leaf springs. Not exactly horse-and-buggy leaf springs. The ZR1 does what, 1.1g on the skidpad with that old-fashioned suspension?

    The 500 cu. in. supercharged V8 engines used in top fuel cars make in the vicinity of 8,000 to 10,000 horsepower.

    I figured that, but since I'm a sim racing guru it bothers me that I don't know what Forza is, yet it's able to be used to test things such as the corvette pace car speeds at Indy?

    Sorry, I can't fill you in on any more than that since I've never run Forza, just heard of it. I belong to iRacing, but to my surprise I really don't use it that much.

    It's all good. My competitive side flared up as well. I figure with my sim racing experience, I might be able to get that bad boy up to a nice even 180mph lap..
