Bandimere....Slowest track in the country???

[Mr. Luos]

An example of some newer cars making passes...



Not bad since I run there and have seen several 11 second passes.
DA has always been 7900-8300 for me when I am there.

Wanting 11.59 next season.

must be depressing racing there

[Spikito]

Impreza beat that vipers ass......I guess it goes to show how FI helps overcome elevation problems

[qwk93ta]

That track is like 5,200 above sea level, right?

[Mr. Luos]

5850 feet.
Normally the DA is above 8000...


Fairly proud of my car running like it does here.

[qwk93ta]

Guess I should feel lucky that the two tracks I go to are 600 and 700 feet above sea level. The DA was 1,200 last saturday when I ran my car.

[Firebirdjones]

Eh,,,that's what they make correction factors for

I have ran all those tracks in Ohio. Nice to be so close to sea level, but the DA with the nasty humidity out there has always been 3,000 ft. or more when I ran. If you were lucky enough to hit a cool day that wasn't raining in late October you were golden,,,,but all the tracks close after that, just when the weather gets good,,,lol.

This Saturday it's only going to be 53 degrees out....the DA S/B outstanding. I'm trying to hit 12s with only a tune, ported TB, LM1, LCAs and DRs. I have an A4.

[Johns00Z28]

Told ya Curtis, ya gotta take that thing down to sea level and see what she'll do!! haha

That's great. Take advantage of it now before they all close at the end of the month.

Being out here in AZ now, I wait for winter so things cool down enough to race at decent temps (in the 70's) The track is at 1200 feet or so,,,but on a cool day in the 70's our DA so far has been around 25-2700 feet.
Not terrible but still not the greatest. You can Imagine what it would be when the temps are 110-115 outside,,,ick.

Really throws a curve ball in my tuning, as I live at 5200 feet and drive down the mountain to the track.

[Firebirdjones]

Here try this http://www.dragtimes.com/da-density-...calculator.php

It has every track in the country. Orion got me onto this. I used my friends weather station for calculations, but after moving I didn't have that luxury anymore. This little site fits the bill. Plug in your day/month/year for racing, your ET, pick the track and it calculates your theoretical ET under ideal conditions.

It has Bandimere at 5,183 feet by the way. But I picked a day in July, middle of summer and it showed a DA of 7,778 feet that day.

I took an ET of 11.90 at 117 mph that is close to what Luos is running and it gave me a corrected 10.97 at 126 mph.

So technically Luos should be close to a second faster if racing at sea level. But even that doesn't guarantee a good DA reading. You can be at sea level and still have DA numbers in the 3,000 + range easily.

[Mr. Luos]

I have seen correction calcs spit out anything from 10.6 to 11.2 at 125-130MPH.
I am not one to claim any time I don't have a slip for though.


And yeah John....sea level would be great. Although I would probably break something.


Bandimere's live timing thing on their site says altitude of 5860 feet.
Been there a ton, it is much higher than downtown Denver which is at 5280.

[Firebirdjones]

Not sure why that site has it listed at a lower elevation. But keeping track of the DA is whats most important anyway.
Without that you cant make accurate tuning changes.

Ya those live calculators vary, but the chances of actually hitting those times at a better altitude are very slim, because the DA will play a part in your ET where ever you go. You could go to Sac raceway where they are about 50 feet above, and still have DA numbers in the 3500+ range,,,and still need a correction factor for optimum theoretical times.
Even at 3500 ft DA numbers your ET may only improve 4-5 tenths over your previous times at 8,000 feet.

[Mr. Luos]

I agree.

Car should still be running 11.6x here, so who knows....

[Johns00Z28]

I take it you got that new clutch put in?

[Mr. Luos]

I take it you got that new clutch put in?

I did.
I need to pull the tranny back down again though and shim the damn slave out a little. Pedal engages too low....and it won't shift at WOT.
Always fucking something.

You don't have an adjustable master???

My wifes car did the same thing, even after installing the required shim. Wife wouldn't even drive it. So I went the adjustable master cylinder route and it's beautiful. Set it where my wife was comfortable. Wife is happy,,,,so I'm happy

[Mr. Luos]

I never had any problem with the basic LS6 master....
Hope I don't have to go that route...that is wideband money.

looking at that cop car he was about 1 sec off from what they run at infineon right off the waters edge
