For those of you who plan on racing at the World Finals for the first time (weather God's willing) I thought I would offer up some info taken from my past timing slips.
The first two are from Speedweek and the second two from The World Finals.
08/11/02 Early Olds injected on Alky 219.4 mph 7053' density altitude
08/15/10 BBC injected on Alky 238.2 mph 6840' density altitude
10/10/09 BBC injected on Alky n.t.** 4186' density altitude
10/04/12 " " " " 229 @4 mi. 4220' density altitude
For us N.A. guys and gals the W.F. air is Heaven on Earth, more fuel+more spark= RECORDS!!!*
* don't get greedy right away.... many have and got to go home early
** My thanx go out to Comp Cams and their P.O.S. roller lifters for their "quality products" resulting in not hitting the five under power both trips to the W,F,'s.
Good luck to all at hopefully both the W.O.S. and the W.F.'s (and of course the BUB and Cook meets).

Piddling on my little scooter and look forward to my first time at WF! how do the crowds compare to SW?

When is the deadline for pre-registration? I can't seem to find it on the SCTA site. :-P Wayno

Nowhere near the same usually, but I'd expect them to be up some this year considering no SW. Also it can be quite cold and the days are for sure shorter. Still this year the event is a couple weeks earlier than when I've gone before. Some mornings then in the 30's with wind and your mind was telling you that you were looking at snow and not salt 8-). I like the fact that they are holding the event earlier than some of the years in the past and hope they continue to do so. It could be perfect temperature wise.
I'm starting to wonder if I'll make SW in the future with the high room rates and the temps that are getting harder for me to handle, especially in a suit. WOS and WF might be my events of choice in the future,

Deadline -- RECEIVED by (not postmarked) Sept. 15.
Entries and details are in the mail this week to BNI and SCTA members -- don't panic!!!
-
Sum, I pretty much decided that I would do the same. Although if you come on Sunday or Monday it is way cheaper. The heat doesn't bother me so much. 95dg and 10%humidity is not bad to somebody from S. Texas. :-D
-
Stan, I'm pretty much panic free. :wink: Wayno

Sumner, you don't have to wear a suit (and tie), just levis and t shirt. Got to visit with John K, Hooley and Scatty Stude at the swap meet.

As I get older I'll probably endorse more of Freud's wearing apparel ....

P.S. Freud just think of how many mph you gave up by keeping the shoes and socks on :evil:
-
Apparently (or maybe apparelently) he doesn't always ride that way -- check the tan lines. He says the darker is SFI 3, the lighter SFI 2. Who knows?

It was easy to get someone to hold my clothing then. Now when
I try that someone shows up with a garbage can to slide down over me.

Will tech be Thursday the 25th and Friday the 26th, or just Friday the 26th?
-
Friday -- starting at 9 a.m. I'm told.

Thanks Stan!

So do you guys find that engines run better at world finals but that the air density is higher with the cooler air and thus increases drag on the car? Which do cars generally run better at? This is mainly considering lower HP cars under 200 mph as we need all we can get :)
-
With EFI, not carb, with supposed compensation for temp and barometer, my car consistently ran faster late in the day when hot (qualifying) than early AM when cooler (record return.) Of course some tuning factor may have been in play as well but suggested to me that the lower aero drag at lower density was the reason.
-
Jack, with our 1 liter EFI tuned for the same AFR we ran 6 MPH faster at WF than at SpeedWeek... Pork Pie is still smiling :-D
We like the dense air, need to talk your EFI into using it :cheers:
-
Last year with our carbs we ran 10 mph slower in the morning than we did at the afternoon. We thought it was a combination of tuning and increased drag. Was just curious what you guys with more experienced had found out over the years.

No argument here. Is why I run an ice water intercooler N/A :)
The DA can change a lot during the day and a tuning change may be necessary with carbs more than with EFI. The drag guys are always talking about "good air" and Udo Horn (on here as hotschue and crew for me) who used to run funny cars would check conditions- pressure, temp, humidity etc- immediately before a run, plug into a calculator and set jetting accordingly. I am sure most folks here are aware of doing this so not saying anything new. But the DA can go up several thousand feet morning to afternoon.
