Kris,
For the record I didn't say they won't be OK, but the other 100 LS1 cars that were all probably atleast .15 or more slower than them it makes a big difference. Oh, and I never saw you on a qualifying sheet anywhere, so I would appreciate if you back off your keyboard a little bit. Also, he didn't kill 20 mph on the 43 run because the actual mph would probably be around 128-129 as he went 128 on the 30 pass. Also, Kris it appears he shut off at the 1000ft which usually kills around .13-.15. That's how you kill about 17 mph. However, to kill 17mph by shutting off at the 1000ft and still go -.96 you have to be able to run about -1.09-1.11.

Kyle, I am pretty sure Trans Am came with both deck lids. It may be the non WS6 trans ams, but I have seen them both ways. They actually had plenty Trans ams that came with the flat hood as well.

I understand the theory, I'm just not buying it. Do you understand that this was the final round of class eliminations. Jumping on the break pedal in a heads up run doesn't make much sense, its not like he was trying to keep from breaking out. Edmond went red anyway he could have just coasted down the track. In my opinion he made a full pass under power to help him dial for the next round.

I don't think the Trans Ams from 1998 up had the flat deck lid, but you may be right. Either way, if they want to stay in C/SA with the flat deck lid and tech says it is ok then I'll do my best to give them a good run.

Re: "Live" from Jegs Northern Sportsnationals 2012
 

You are correct. From '98 and up the Pontiac Formula TransAm Firebird had the spoiler rear deck lid. The Pontiac Formula Firebird had the flat deck lid. I had one of the first LS1 FB to come out. Woodro will probably remember! I bugged him enough! Jim

Hoods available in both flat hood and Ws6 options. CR

Re: "Live" from Jegs Northern Sportsnationals 2012
 

No, I did not know the circumstances of those runs. Just thoughts on how it could have played out. I understand your opinion also, but most people don't have to run it out to know where to dial.

I don't run a stocker so don't shoot me for commenting! I know one thing the LS1 cars just slid down the ladder some more to the new cars.

Re: "Live" from Jegs Northern Sportsnationals 2012
 

It should be FI, carb, and the new cars in their own classes!

Re: "Live" from Jegs Northern Sportsnationals 2012
 

Heck of a MPH for a 10.25.

Re: "Live" from Jegs Northern Sportsnationals 2012
 

yep i wonder if we should blame the timing system Pro stock does not get any funky MPH they are real low just wondering?

Re: "Live" from Jegs Northern Sportsnationals 2012
 

Pro Stockers trip with the nose on both the mph marker and the finish line, so the speed calculation is correct. You only get the errant high numbers by hitting the mph mark with the tire, and then "shortening the traps" by hitting the finish with the nose.

I've been to one track where my mph was way different from lane to lane with my Turismo. One of the mph beams was higher than the other, so the nose would catch in one lane and not in the other. That car will trip with the nose just by lifting!

Re: "Live" from Jegs Northern Sportsnationals 2012
 

Many topsportsman cars at columbus had goofy numbers at the 1/8 as well as the 1/4 mile marks.My geuss was the height of there equipment was the problem as some racers raised there ride height and problem went away.There also was a difference lane to lane possible track crown

Re: "Live" from Jegs Northern Sportsnationals 2012
 

Being a numbers guy I thought I'd run some numbers on trap speed and time. Not trying to stir anything, just add some logic and engineering to this discussion.
Common number for speed is 60 mph = 88 feet per second (fps). With that we know 120 mph = 176 fps. The speed trap is 66 ft long so it takes .375 seconds to go thru the traps at 120mph. 66/176 = .375. The speed given on the timeslip is not a top speed but is the average over the last 66 feet of the 1320.
Now if we look at 125 mph or 183.3 fps the time required to go 66 feet goes down to .360 seconds. 130 mph is .346. So a 10 mph change from 120 to 130 mph only takes .029 sec.
So the opposite is true. If you dump .029 sec in the last 66 feet starting at 130 mph you will read 120 mph.
If we say the car has a 3 foot nose or the distance from the nose to the cross section on the tire where the beam would hit with the nose up all that has to be done to see the difference is redue the calcs using 63 instead of 66 feet. That gives a trap time of .357 at 120 mph. That will trick the computer into printing a 126 mph.
I guess the timing computer has a formula or small data base the the trap time is input into and out pops a speed. Doesn't matter if its a car, rail, bike if snowmobile.
Just a little info fo thought. Sorry for further hijacking the thread.
