180 hp Caddy Motor

Duh,the mph doesn't go with the et.

Well, when you have a basic engine like the Olds 350 that has been flogged for YEARS by racers, you (as an NHRA Tech) should be able to look at the factored HP it has accrued over the years, to see what the potential of that engine might be, minus the 4bbl, better compression ratio, and better intake manifold that is absent on the Caddy F.I. version.

Then, you'd have a little better idea of its potential than just "buying" the factory rating to begin with.

NHRA sure didn't waste any time adding horsepower to the "NASCAR Hemi" before ANYBODY ever put one on the strip. They're usually not shy about that sort of thing.

As far as waiting for the AHFS to take care of the problem, sometimes, you're in for a L-O-N-G WAIT...

I still think they could do a better job in cases like this. Do they live in a cave???

You are correct in a way, however, the way the speed is measured from the ET is done with separate photo cells. This is an excerpt from the NHRA Website section called:"Drag Racing 101 - Drag Racing Made Easy":

"Two Separate performances are monitored for each run: elapsed time and speed. Upon leaving the staging beams, each vehicle activates an elapsed-time clock, which is stopped when that vehicle reaches the finish line. The start-to-finish clocking is the vehicle's elapsed time (e.t.), which serves to measure performance. Speed is measured in a 66-foot "speed trap" that ends at the finish line. Each lane is timed independently."

Since you can scrub MPH at the last moment; the E.T. and the weight of the car at the scales after the pass, should be the real indicator. There are many out there that are running way more than the class minimum; therefore, when they get hit with horsepower, all they do is remove weight to stay at the top.

Thank you. You got ahead of me.That was the next phase.Those two parameters would begin flags waving.But I guess Nat'l tech has other things to do.

Yeah, Ed, they're busy checking the "telltale" needles on the NHRA-supplied BOOST gauges on the many turbocharged cars... That takes, oh... 30 seconds, or so... LOL!

Could NOT resist.... sorry. (I don't know when I'm well-off...)

Isn't it true that a car that slips off the starting line will have a low ET & high MPH?
Could it be some racers make or buy more hp than their set up will handle?
Or are they running throttle stops? :~)

Adger;
The MPH discreptancy is more that the effect of tire spin.Watch A,B,C cars get alot of air and if it's known
it's a fast day look at the mph.Over bloated weigh ins is another reason.You must be having a senior moment,name me a car in S/SS using a throttle stop.Can't argue about the money part though.There are some guys with more money than brains.
