Re: Driving 4000+ miles from California to Florida for Flight Judging!
Thanks for the story about this 65. I was there when they pulled in and had no idea of the background. Actually as so few cars showed up for the judging field I thought they were allowing street car parking just to make it look good. Wow! how wrong I was. This year I spent most of my time at the auction and the for sale car lot. My son bought one at the auction, but didn't sell one from the car lot. Wore myself down so much that today I'm still home with the flu (first bought in 20 years). Even the flu shot didn't help. From now on this old guy will rent an electric cart to get around - be it Carlisle or here.

Update.........
Luke sent this via email last night. At 8:37PM he snapped a picture as he was driving. His car is amazing.

Re: Driving 4000+ miles from California to Florida for Flight Judging!
I bet you don't pass by many gas stations turning 4k rpm and pushing 85 mph
Nice.
Hey Mike Johnson, 4k rpm for 15 hrs on the freeway is a fine new idea for demonstrating American muscle to environmentalist extremists!Comment

Re: Driving 4000+ miles from California to Florida for Flight Judging!
I think I'm close to 4K rpm at 85 mph just with my 3.55 rear. Can't imagine 4.11 or 4.56 on the highway. I believe the trans wouldn't matter, since I believe 4th gear is 1:1 ratio, whether it's an M20 or M21 like I have.Ha! It sure is. Imagine the "carbon footprint"….
I figure the car must have a 4.11 of 4.56 rear if he is in 4th. Driving a car like that any distance on a freeway at those speeds should merit him a medal of some kind, and he should check the car for loose screws and nuts from all that vibration. I also assume he didn't drive from Barton Rouge to El Paso yesterday.Comment

Re: Driving 4000+ miles from California to Florida for Flight Judging!
Right, it's a 3.70 in Luke's.
Correct, He left Kissimmee Sun AM early and made it to BR-LA, then Monday to El Paso and barely beat the bad weather.
His email was Monday night late from the hotel to Chuck. He must've sent himself a text/email with the photo when he was driving. Then that night sent the message out with the pic.
John Quam forwarded my email address to Luke yesterday so I can get live updates now.......more to come.

p.s. i gotta' get some work done over here and get away from this 'puter for a while.

Re: Driving 4000+ miles from California to Florida for Flight Judging!
I read the speedometer as 84.
Axle ratio = 3500(60)/84(775) = 3.23
The above assumes OE tire revs per mile and OE speedometer gearing, and assuming the speedometer reads three percent high, which is typical, it's probably a 3.36 axle. A 3.70 would be taching about 4000 at an indicated 84 and a 4.11 would be 4333.

Re: Driving 4000+ miles from California to Florida for Flight Judging!
Duke,
Luke's tires are definitely not OEM. I didn't see the size but they're big fat radials on KO's. His eyes may have been a little blurry when he sent the late email, as I read 84mph also at about 3500 RPM on the tach. I'm pretty sure he said they're 3.70 gears but I could be wrong.
Regardless, he was flyin'! Did about 1,000 miles Monday. When he came the odometer was around 06500(actual 406,500). It looks like 08211 when he took the pic. I just G'gl Mapped it and it's 1718 miles between Kissimmee and El Paso so that's pretty darn close.

Yes, those tires look very short. His speedo/odo probably registers around ten percent high. The actual error could be computed if we know the tire size.

I was using this online calculator, but I assumed 84@4K and 205X75X15 tires.

Eventually I'll get the tire size info from Luke, that is if he has tires left when he gets home. Their diameter is decreasing rapidly as we speak.

Re: Driving 4000+ miles from California to Florida for Flight Judging!
I've lost track of how many times I've ranted about "online tire calculators", BUT THEY ARE INACCURATE AND MISLEADING!!!
They calculate revs/mile using inflated OD. That will work fine for a steel railroad wheel, but pneumantic tires deflect under load and actual revs per mile are greater than the above "rigid body" calculation.
I have never run across an "online tire calculator" that properly computes an accurate answer.
It's so simple! Revs/mile specs are available on manufacturers' and big retailers' Web sites like The Tire Rack. Just click the "specs" tab for any tire you are looking at in a specific size. If the specific manufacturer/model is not listed, one of the same size will be very close because the revs/mile spec has to conform to a very narrow range specified by Tire and Rim Association rules.
Once you have tire revs per mile:
Speed at 60 = revs/mile X axle ratio (for a 1:1 top gear).
Once you have the above value you can simply linearly proportion to any other speed.
Example: 3.08 axle, 760 rev/mile tires, 80 MPH:
3.08(760)80/60 = 3121. At 80 my SWC tach reads about 3100, so it's pretty close.
You don't need a computer. A hand calculator will do fine or the back of an envelope and a pencil.
I've listed OE and common replacement size revs/mile many times, and any other size is available as described above.
205/75R-15s are typically about 766 revs /mile. Do the calculation as above and compare it to your online calculator to see how much error it has.
A typical tire's revs/mile figure will increase about 2 percent between new and 2/32" remaining tread, which is the point that the wear bars are flush with the tread surface.
Unfortunately the calculation is vastly complicated if you want to compute speed in a gear other than 1:1 such as a lower gear or an overdrive top gear. For that you'll have to hire a rocket scientist who has access to a super computer.

Update from Luke below....
Rich
p.s. I have access to a supercomputer(KSR 1 I installed in the early 90's) at the Oakridge National Laboratory in TN if anybody needs some compute time.
I'm too tired to calculate how many buttons are on my shirt right now, so you guys figure it out.

Hi Luke, Hope all is good on the ride. It's around 4pm where you are Ithink. Where are you?
I'm putting your status up on the corvetteforum and NCRS forum.
Rich
p.s. what make and size are your tires? Some of the guys are trying to figure out your tach and
speedo accuracy and your rearend ratio. You said3.70, right?Comment
