How to slow AA/FC
 
I realy do not enjoy funny car anymore but I know one thing that would slow them down, make the body to resemble a Mustang, Camaro, Chalenger not these submarine contraption. I brought a friend to the track a while back and she said "what type of car is this" when I told her she couldn't believe it. I'm sure that it would slow it them down and maybe the car might be recognize. My three cents

Might help in Pro stock also. I saw a Greg Anderson Car in COlumbus. Too Generic to recognize, just "evolution". ( Race real cars or call them Funny cars also.)

If you want to slow down these cars how about only spraying the track to 100 ft. Debate over. You would see a definite decline in performance. Would the real racers be able to get down the track? Does NASCAR spray there surface? If not how fast would they be going on a glued surface? They have adapted to the surface they have. Not visa versa ie bring surface to the vehicle. I am not sure this is a good example, just a thought. Change is hard. I think we need a change.

Back to a single mag and smaller fuel pumps.Instant power reduction.Probably a better show.And maybe a bit less expensive.Limit amount of teams to 2 cars so that we don't get sick of watching Schumacher/Force standing on the starting line so much.I'm sure that will never come to pass.Hows about it SSDIV6?

Ed how will this effect Pro Stock? Or even Comp. The change must apply to everyone. Or classes will complain they are being singled out.

The title was "How to slow AA/FC".Besides,we sportsmen racers, from comp down rarely go into the net or pebble pit.P cars usually only have problems when track prep is doo doo.PSBs biggest problem is bumpy tracks.T/F and F/C and the alcohol cars are time bombs.Slowing them down a bit would make them a bit less expensive and I think make for closer races.But that's only my opinion.

Ed who would doubt you ! You drive a Nash, or a Rambler,or something like that ! You can't be all wrong or bad !
You could show them how to go a little fast ! Just kidding !

Make them use stock cylinder heads with no porting-ok, maybe acid dipping allowed!

I agree; de-tune the cars just like NASCAR did when they enforced restrictors.
One of the issues that many have pointed out and agree is the cars today are way faster, and many of the tracks do not have the means to provide an adequate shutdown area.

Just take in to account the following:
200 Miles per Hour = 293.33 Feet per Second
250 Miles per Hour = 366.67Feet per Second
300 Miles per Hour = 440 Feet per Second
...you are covering a lot of real estate very fast!!!

The simplest, and least expensive, solution would be for MSD to reprogram the already mandatory Rev Limiter to take timing away at a lower RPM than the current 8200 - 8300. If anyone knows of any reason why this wouldn't be feasible, please let me know.

Im obviously not a fuel crewchief, but, I would tell em all, in January, that only a 10-71 size blower is legal, set boost level at 25 psi, by pulley requirements, one mag, single plug heads,and plug the other hole. If they can only get so much fuel thru the motor, it will only make so much power.Leave the 3.20 gear in em, and they wont over rev. Clutches would be 3 or 4 disc, not 5 or 6. They can run all the other stuff they have, short of camshafts. Heads might be too big, but after you wear out what you have, work on a new head. Digger rules would mirror FC.
They were loud and nasty in the 70's and early 80's, but a good deal slower, for a while anyway.

AA/FC's are the nostalgia cars......
Today's Big Show cars are just FC's................:-)

Kenny, I'm obviously not a fuel crew chief either, but why make all of those expensive changes. As I proposed in my earlier post, have MSD reprogram the already mandatory Rev Limiter to take away timing at a lower RPM than the current 8200 - 8300; that will force the crew chiefs to flow less fuel at that point, and consequently, make less power. If a 300 RPM reduction will slow them enough, so be it; if 1000 RPM is necessary, then so be it. In my opinion it would be the most cost effective way to accomplish the goal of slowing the fuel cars to about 300 MPH which is where the NHRA wants them to be.

Re: How to slow AA/FC
 
I was thinking that the original seetings in those rev limiters caused em to knock the rods out, fairly often. I am probably wrong about it, but it always looked to me, that they REALLY loved spending money like it was on fire. Electronics, IMO, will be overcome, by a smarter programmer, in possibly in their cases, a better re programmer. AJ and another one got popped for altering it once already.
The more mechanical means, would be more effective. Simply making them run a smaller pump with 95% else remaining the same, is only a waste of money and time, and a smoke screen for the masses to swing their hands in.

My first experience, drag racing wise, was a 32 car FC race in 76. I was blown away by that. But, in a short few more years, seeing Stock,SS and Modifieds and etc., was the hook. I will always enjoy watching FC, but the are not the jazz they once were, to me.

You do not want to take ignition away from the fuel cars. When you do, they'll start putting holes out and hydraulicing engines at about 10 times the current rate.

Take away 50 cubic inches, take the blowers down to 12-71, allow no overdrive, and cut the compression ratio. The only thing they will have to buy now is the blowers and the pulleys. Make the 50 cubic inches and lower compression ratio effective at the 2011 WinterNationals and announce it now, so the 50 cubic inches and the lower compression won't cost extra, they'll do it when they place their orders for next year's parts.
