Mustang MPH?

What is the reason Stinnett moved to AA/SA from A/SA? Does he get to take weight out?

[Tom Moock]

Weight, if want to known if someone is running heavy? or on the min weight, it not rocket science, all you have to do watch them when they scale after run or ask the tech person how much number 5704 weight at the scale, heard all the story about being 100 pounds heavy or 200 heavy

Yes, the AA/SA weight break is 7.50 - 7.99 lbs/hp; the A/SA weight break is 8.00 - 8.49 lbs/hp. Assuming that he was running at the class minimum weight in A/SA, he can remove .50lbs/hp which=212.50 lbs (.50 x 425hp).

These cars on kill will run 9.20's possibly teens all day long with a pulley change and some tuning. Next topic.

Word is: last qualifier 109.80 mph @ I/8. The person who ran with this car was walking around the track and showing the ticket to anyone who wanted to look. He also checked the weight and said the car was 170 pounds heavy. This stuff isn't going away.

Several years ago, I attempted to get the Pontiac GTP's into the Classification Manual. Ironically, even though Pontiac was the "Car of NHRA", they didn't have any of the 1997 & up Grand Prixs listed in the Manual. Len Imbragno tried for several years, and even made extra classes for the FWD cars. But they weren't classified until after he left.

The reason I mention all that is, at the time, I asked about changing the pulley diameter. I was told that only the STOCK pulley diameter would be allowed. Rules for Supercharged Stockers aren't addressed in the rulebook, but back in the old '57 Ford days they had to use the STOCK pulleys. Hardly anything else has changed in Stock since then, so I was just wonderin'.

One must remeber in the day (1957) Ford had 2 sets of pulleys one set for Stick and one for set for auto.

I have been told that the stock OEM pulley with the correct tooth count and part number must be used on the new Ford. As far as the turbos, I have been though many tear downs and can tell you NHRA has all the specs they need to check the housings and cartridges. They check both wheel diameters and for clipping. The turbo must be completely stock as produced with the correct make and part number. Jim

I think that the first step in this whole deal would be to get some kind of rules clarification from the NHRA in regards to allowable changes to turbos and superchargers. I was under the impression that they have to be unmodified OEM. Maybe Travis could write something in regards to what they do check?
