Ok guys, what would group think about having a tiger or C.AT. Team at the 24 hour race at Daytona.......I know I know......But it would be cool as ------- :).
Just food for thought..

Big difference

24 hours at an average speed of 75 mph is less than 2,000 miles. The difference is WOT 90 % of the time rather than less than 1% of your annual miles. Shifting near red line routinely rather that just when your sure there is no cop around. And what about every turn at 0.8 to more than 1 G. All together temps in the dif, trans and wheel bearings will be beyond anything driving a couple hundred miles down a freeway between pit stops.

That kind of abuse is a lot for a production car to take much less a vintage racer. Off the scale compared to attending an occasional autoX.

Right.............why would you drive it that hard? It would be an endurance trial....thinking ruining it a 80 mph....even have a cruise control to use. ;)

One reason would be to win the race !! Even running at 80 mph with a top loader and the tiger gearing you would be in the low five grand range and I give a stroker motor maybe eight hours tops....It's a FORD you know...

Whatever....I run 78 mph @ ~3600 rpm and can do it ALL DAY AND NIGHT LONG. My trip to Maine a few years ago I ran two 12 hour days to get there. With a couple of drivers, 24 hours ain't crap.

And BTW, don't want to win the race, just prove a Tiger can run 24 hours with no issues.

Moon Dawg - you should have put a Chebby in your Tiger sense you are such a fan.

I would never put a Chevy in a Ford car no matter how much better it might be
so just call me a purist....but that new generation 5 chevy motor just might fit
and so think about it...450 hp good for 50,000 miles on warentee hooked
up to one of our Tremec TKO side shifter transmissions.....Talk about a Cobra Killer...quarter miles times in the 10's.....Hmmmmmmmmm

I just looked down the list of Le Mans overall winners and not a Chevy in sight. Of the 4 times Ford has won, 2 were with the same basic small block engine as Tigers. Ford even used the internals from the toploader in the later GT40 transmissions because of their strength and durablility.

With 24" tires and 2.72 gearing, that's 5700 rpm at 150mph, sounds doable. At a peak rpm of 6500 rpm, that's 170mph, pretty dang scary in a Tiger.

Why would we need to run a Tiger at Daytona.. its been done before and if finished.. and funnily enough it didn't do that much better than the alpines that ran in the previous years.
 
Relax.....

This was just a thought to help get thru this winter to good driving weather.....plus it is soon to be racing season.....i completely understand the limits of aged technology.....but.....it would be a lot of fun to see......maybe we should have or own race.....maybe 4 hours....then a break for lunch.....

Hey Gary: 44 years ago B382000078 and I did a measured VASCAR mile both directions and could not get to 170 mph. The car actually crouched down in the nose, but did average an honest 168.3 on common street tires of the day.

Randy what rolling radius tyres were you using and what diff ratio... figuring that you managed to pull 6500 rpm that's 25.89 mph per 1000rpm

Rubber was the 70's series of the day (figure maybe 175 or 185's) so they were tall-ish. Stock rear end gears. But the 289 was a high domed critter with a very radical cam, Offy 360 high rise and a 950 Holley 3-bbl with a large bell vacuum control for the secondary. A Sun tach could show upwards of 8K smooth spinning anytime. It would never jump off the line and required a good rolling rpm before feeding it. Then it would snap necks. The bonnet had a rear facing lump to clear everything (it's here somewhere). The motor was sold to a local circle track racer and still exists today in his workshop.

didn't hugh guynes get his tiger to 162 mph in a measured mile at the old air base at wilmington ohio last summer? the details are in a past te/ae news letter. it wouldn't take long to cover the mile at those speeds.
