Mustang MPH?

[JRyan]

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

What's funny about these boosted cars, and I know we are beating this issue again into the ground, is that as you keep loading these vehicles down weight wise they will get faster. The CJ's, no matter how they get weighed down, if the chassis is set up right they will not slow down. Break parts, yes, slow down, no.

Now they can defy the laws of physics too? Please explain.

Thanks for clarifying. I was pretty sure that the forced induction combinations didn't have a "blank check".

[Bruce Noland]

It looks like the "blank check" has already been cashed. The current AA/SA record holder has never posted a 109.80 mph figure in the 1/8 mile. And this is only the second race for these cars.

Jim W,

Respectfully, who gave you this info on the pulleys? Why is it that everyone has all this information and no sources to back it up. Hearsay is CRAP! This must be a really smart person who fed you this because they don't know the first thing about late-model supercharged vehicles. The CJ does not use a cogged blower drive, so there are no teeth to speak. Have fun counting those teeth! This goes for the drive pulley, or the driven pulley as the blower is driven by a serpentine belt with a sprung tensioner.

Furthermore, the rulebook states "aftermarket pulleys permitted." It currently says nothing about pulleys used to drive blowers, nor does it state anything on NHRA.com. Where do you people get this information from? Please, I know many of you are bothered by the CJ, but if you are going to come on here and post, at least properly inform yourself in order to sound intelligent about the topic and list facts backed up with a legitimate source. Only then will you be taken seriously.

And who is "loading them down with weight." Simple physics, a lighter object can be accelerated quicker than a heavier one.

No Evan, your wrong. They're fords, therefore they defy the laws of physic's and logic, they are evil, EVIL I TELL YOU! They have special cogged serpentine belts which add hp! I heard they put a cj engine in a dumptruck to "load it down" and it went 9 flat!!

THEY"RE EVIL!

EVIL I TELL YOU!!!!

THE VIN NUMBERS ALL START WITH V FOR VOODOO!!!


MUHAHAHAHAHA, YOU ALL WILL NOW SUFFER THE CONSEQUENCES!!!

Seriously, this has been beat to death will logic and constructive input. Now it's just demonizing them.
There is nothing left to add so others will "I heard" or "I think". Again, it's all ford bashing and sour grapes unless the uproar is levelled against the turbo dodges/etc too.
