I was just thinking. (that gets me in trouble sometimes) but the Pro Stock slow up approx. .17 right. I help Craig Bourgeois on his A/ND comp car and we slow up approx. .16 . But both cars slip thru the wind better than most. The thin air might have more to do with it then we think. The factor NHRA uses is .9830 to convert to sea level and the slower you go the more it effects th ET but you put Marv's wagon out there and it is cutting the air with ease? Maybe ?

p.s. I know my golf ball goes farther in Vegas than New Orleans.(but my money doesn't)

Hey Guys,

The simple solution is every-run counts no-matter what track,then at least it levels the playing field alittle.. See right now you guys can go as fast as you want with no-HP and set records at factored tracks with no-HP ... Doesn't sound right , yah I know we have fast sea-level tracks and we can get HP....I do think counting everyrun would help..... Good Luck to you guys at the World Finals, hope you have great weather............ Dave...1033/stock

Here is my opinion why everybody runs hard in Las Vegas.

The starting line in Las Vegas is one of the best we run on out here on the West Coast.
When the air is up to 3500 plus feet of Density Altitude you can really lean on the car and make it run faster relative to the corrected index than you can at sea level. You can absolutly hammer the car on the starting line and hook it up. The altitude allows you to mask chassis limitations since you don't make as much power.

I don't think Frank Grossi's car was working well at Indy. He had a new engine combination and they had not had a chance to sort it out. He is getting a handle on it now but I think there is more left yet. And if you watch he almost always has ice on it for the qualifying runs.

As far as the factoring goes? Who cares? It is an imperfect system run by imperfect people. It can never make everyone happy so either accept it or run a class where you are not subjected to it. Seems easy to me!
Bryan...you hit the nail on the head, you are ABSOLUTLY CORRECT...much of what you lose at Vegas altitude, is made up because how well the smooth Vegas track works...Vegas has the best surface in NHRA

And one more thing. The track is good all the way down. Case in point. During my last run my car would not shift into high gear. It went to the rev limiter in second at 8500 RPM. I backed out of it and was stirring the shifter to get it into the nice clean nuetral position afforded by the latest technology in automatics. Well I was not able to get it into neutral, but I did manage to knock it into first gear. I don't know where the RPM topped out (the tach only goes to 10,000) but I can tell you it never thought about skidding the tires. It just spun my little old 454 up to the moon. At most tracks this could have resulted in a tire smoking wild ride. Not Las Vegas!
It was running when I turned it off but not well and without oil pressure, oups! Turns out the nut on the shift arm was not tighned and it backed off. I sure wish it had just fallen off.

I guess I made a mistake by using grossi as a comparison as he only ran a 9.28 at indy and he didnt have all of his stuff sorted out!!!!! Lets use John Shaul as an example he went10.26 at indy and a 10.24 at vegas maybe John doesnt have this combo sorted out either. MAYBE ITS THE STARTING LINE???????????????????????????????

Let's have you get analytical instead of being subjective. Go back and read the posts by Bryan and I; weather and track conditions. Then go pull the weather from Indy (temerature, humidity, barometric pressure and corrected density altitude), say the best weather during qualifying. Then compare it to the best weather in Vegas for qualifying.Then think about the obstacles of a high humidity day of racing compared to a low humidity day of racing. Track conditions, tuning differences and how they relate to track conditions, etc. I think if you really look at the numbers, it might make sense.

Then, after you've analyzed all the data and see how good Vegas is in November racing, go re-evaluate the data and compare it to July. Then see how great it is in Vegas because the altitude factor knows no season, it's a 12 month constant. Better yet, look at the Mopar Nat's in Denver in July. When it's 105 degrees on the starting line and your 3500' or so closer to the sun, you'll really love racing!

Exactly Jeff. Vegas at this time of year was .06 better than Bristol. Jason Line was #1 @ 6.78 I believe.That number would have been good for #16 @ Vegas. Both good tracks.

I guess were running pro stock now

I agree with dean keep the tracks factored and go to afhs across the board lets see how many sandbaggers there are then??????????
