Whoooeeeee Woody   I love the graph---maybe we can plot my 3 mile trap speed and get an IDEA of what I may be able to do in Aug.

THANKS

Ps. that graph really points out for the slower cars:

Its is a 4 mile drag race with a 1 mile trap!!

Very little increase in the last mile

Sparky,
Just for $hits and grins do you know what the weight was on the rear axle of your old car? As I remember it was also a flat bottom car, did you run it with some rake? Ever dyno the engine? My guess is a 500+ inch BBC on gas probably is good for 1100 to 1200 hp depending on displacement and rpms.

Your two timing slips probably have a lot to say regarding total available horse power, aero i.e. frontal area x coefficient of drag plus rolling resistance plus skin drag. Your old car looks like it could probably run right at the 310 mark with the hp you had at the time regardless of the length of the course. Definitely against the "aero wall".

The other thing to consider is the difference in air density. If we "assume" you were jetted correctly at DA 6247 then DA 4848 would give you about 5% more HP NA. About 25% of that would be consumed by the aero drag of the thicker air. If we plot that on the DA 4848 then you should have gone about ~2 mph faster on that run. Lots of assumptions, so ~310 instead of ~312 is pretty durn good. Besides the hats don't come in different shades of blue anyway! 

I gave you another curve to shoot for!

Rex,  We had just over 930 dyno,  2015 on the rear 1250 on front  yes it had 2.5 deg rake

  Woody---lol

This thing should go a little faster---BUT we still have wheels and tires OUT  Lets keep it simple and knock about 123 off that 

found some scales today to weigh and CG this thing

[Podunk]

Hope I got photo thing figured out.

[Podunk]

Well one worked!

[Podunk]

How about one more.

[SPARKY]

Wow Terry are you sure those things are going to hold air?  It has a big hole in the middle of them!!  lol

[Podunk]

Thats where the air goes in. We'll plug it with racers tape.

Beautiful work  ,

Sum

[tauruck]

I second that.

[SPARKY]

Mouerman--- does do good work, especially for someone so geographically challenged !!  Not only does he live East of THE state line but he is a YANKEE to boot---lol---

COOL,   never seen a 12 to 13 inch Micrometer before!
