roadster weights ?

Roadster943, if you are running a wet sump oil system, you might
want to add 2 or 3 quarts of oil so you don`t run out at the 2 mi.
Thats the first thing lots of people learn at B-ville. :wink:

No spool for me-no spins in 11 years-247 @ B-ville-225 on the dirt :o

We're one-wheel drive with only one wake-up problem at the 4-mile a few years back with a side wind.  Noticed we were looking at the pits!  Always been able to get out of the throttle, then pull the chute.  Lots of (early) times the chute never came out, but backing out of the throttle or putting in the clutch slows the brick down so much we never knew it wasn't out.  We easily get off by the 5 3/4 without a chute.  Some times the 5 1/2.

Roadster943,I'm with PROMACHINE all of the wet sumps we run at b-ville or el mirage a min 12 quarts of oil(I use mobile 1 syn.),my dry sump use 5 gallons of mobile 1(cheapest thin that will ever go in that motor). We do not use a spool either 217elmirage ,and wheel tach 241.at the salt. Aren't Roadsters cool.  Have fun Eric

...although I must admit, I would love to run a slammed 50 nash on the salt.  Think about it, you could be spinning thru the lights, and set the record both ways....lol :roll:

'29 Ford Roadster, Craeger overhead, Winfield cam, Duel down drafts, Bobbed fenders & no running boards, Chrysler grille shell, Solid hood, Chopped windshield & top, Dual exhaust down the right side. I've got pictures of the car at Muroc in 1938. Dad worked at the Western Auto in Glendale before becoming a wind tunnel model maker during the war. I was and still am one of the "lucky ones"... J.D.

I've been digging in the archives and found this post. Very interesting.

I am confused by the discussion. I understand the 'dart concept', which is a great simplification, however, everyone goes on to state that they are biased with weight to the rear: -Followed by reports of going through the traps backwards :D

If I want to go through the traps with the front tires first, should I put more weight in the front? Of course I'm being facetious. I'm reading up as much as I can, but the real world results are throwing off my physics as usual.

From what I'm seeing, a front weighed car will lose traction when hitting the 'wall', but you still need enough weight on the front to keep the backside from coming around. Am I right? And at least in roadster dynamics this means more weight on the rear.

So let me have it. Am I on the right track? How do the production class cars keep the car going forward? Maybe that should be a different topic?
