Revised FC Qualifying?

[Smiley]

What happened?

I see someone went from inside to outside but no explanation.

Looks like Cruz Pedregon is out and Justin Schriefer is in. I don't know the details but Cruz was in around 4th or 5th. Must have gotten tossed for something ?
Got this from NHRA notes.
Justin Schrieffer, driver of Dale Creasy’s Tyrant entry, was originally not qualified but was later inserted into the field after Cruz Pedregon’s final run was disqualified when it was determined that a low hanging part of the body resulted in a false elapsed time.

It was something about the body being too low.It tripped the lights wrong.

 

[turbo ken]

The body on CP's car was too low to the ground right behind the front wheel wells, the NHRA measured it at 2" (it's supposed to be 3" of the ground), his 60' time was way wrong for the ET he ran which caused the NHRA to look at it.

Thanks, knew it was Cruz but didn't want to be a spoiler if anyone hadn't watched.

Was it a new body for that run, or was it not latched properly?

I don't know if it was a new body or just mounted differently.. but one thing is for "SURE"

CP won't have to "Fear For His Life" (See what the Ace Ed Mc.C has to say about this) on Sunday when FC runs...

 

[mastertone]

Good, now we won't have to hear him crying on Sunday

I can see being too low in front of the tire would trip a timer early....
but they said the body was too low BEHIND the tire...

 

[Sean D, shondoo]

As far as I knew, they stage with tires and trip the downtrack timers with the bodies. I understand the theory that if he had something behind the front tires that the timers wouldn't start as quick, but I thought there was a guard beam in place to take care of that?

This may have something to do with the DQ:
BODY
A 2000 or later model-year NHRA-accepted coupe or sedan body
of a type originally mass-produced by automobile manufacturer
(domestic or foreign). Must have originally measured 63 inches
wide or more at centerline of front and rear axle. Maximum body
and/or roof width cannot exceed stock dimensions. Duplications of
production bodies of fiberglass or carbon fiber permitted. Body may
be lengthened or shortened. Front and rear contour of body must
resemble same configuration and design for specific body used;
holes for air passage prohibited. Any modification to body not
described in this Rulebook prohibited.
Maximum body width variation from front to rear is 6 inches.
Minimum body width is 60 inches when mounted. Modification to
the lower, rear corner of the front wheel opening(s) may be allowed,
IF required to meet the clearance for starting-line timing lights. In
side view, the body should present clearance, all the way across
the car, 3 inches from the ground, extending for a length of 12
inches + 1/4-inch max, rearward from the front spindle centerline.
Any exposed edges or openings as a result of trimming the wheelopening
corner should be patched and refinished. Such
modifications must be authorized in advance by the NHRA
Technical Services Department and accepted upon completion.

Hmmm...how do they get away with hinged tail lights

Zappy, Having the body too low behind the front tire will result in quicker times as the clock won't start till the lowered body clears the beam, instead of when the tire clears the beam, thus giving the car a running start and a quicker ET. It will also result in a quicker 60' time which, as I understand it, caused NHRA to take a close look at his car.
Also keep in mind that the front trees on those cars have adjustments where they sit on the chassis. They run them with the very front on the body up from the chassis so at speed the body is pushed down blocking air from going under the body and also tripping the finish line beam with the body.

JMO. As I read the rules, the holes for the PASSAGE of air through the body are not allowed but the taillights allow the air a way out from under the body.

But like I said in my earlier post, Rocky, why wouldn't the guard beam take care of that?

You would think it would Sean. I have no answer for that.

Rocky this is an example of the aguement I get into with the boat guys(fans) and when they try to compare there ET's with the cars. because of their 125ft running start. if they had to start from a standing start they should be on the average about 1.7 seconds slower than they are now.

Sorry to hijack but it is the perfect example of a running start and advantage to ETs

 

[Sean D, shondoo]

I have been around a long time and what am I missing? every starting line I have been to or staged a car, I have only noticed 3 lights(beams) at the starting line not a 4th

Correct. Prestage, Stage and the Guard beam.

I'm not sure of the specs, but I was under the impression this beam was there for situations just like this.

Sorry for the brain fart your right I dont know what the hell

Thanks Rocky, got it.
