Throttle Limiters
 

What would happen if the NHRA policed all those restrictor plates, disconnected secondary mechanisms, and throttle travel restrictors, etc.?

Re: Throttle Limiters
 

Daren, you are not giving and considering the creativity of racers. Someone will eventually find the way to circumvent it. Besides, I don't believe NHRA has the manpower to inspect Stock and Super Stock class cars every run.

Re: Throttle Limiters
 

Not at all. I have been looking at how to get around this for about a week.....

Re: Throttle Limiters
 

Why wouldn't they just plug the desired ET into their Grid and/or data recorder?

Re: Throttle Limiters
 

Don't think for one minute that they can't!

Re: Throttle Limiters
 

You would need a device to measure the lane distance.

Re: Throttle Limiters
 

They put that information right on the timeslip. You just need to make one baseline run to see what distance it says.

Re: Throttle Limiters
 

For whom would this benefit?

Re: Throttle Limiters
 

I know someone who uses them and NHRA allows them.

Re: Throttle Limiters
 

While your at it don’t forget about the modified cars running BS with one carburetor, allowing them to run CM that has 2 carbs lol guess that could be considered a restrictor only running one carb when you can have 2 �� I forgot, where only after the EFI cars ��

Re: Throttle Limiters
 

Billy, You have been complaining about this for a long time. If you think it can be done show us how to do it. I really want to know how it’s being done! Mike McMahan 2543 H/SA

Re: Throttle Limiters
 

I use a grid, you can look at my data if you'd like at any time. But nowhere that I have seen can you plug an ET in anywhere. There's a G-Meter that works with a grid, or basically a driveshaft sensor, that you can run which I'm 100% against and should be illegal on every car in the staging lanes in Stock and Super Stock. Those can easily be policed in the lanes or at fuel check or any damn place.

Re: Throttle Limiters
 

You are correct; you cannot input ET's into an MSD Grid.

The only device you can input the ET is a crossover box that works similar to a delay box. It allows you to react off your opponent's side of the tree only when you are the quicker car. You enter your dial in and the opponents dial in into the delay box and it automatically calculates the difference.

Re: Throttle Limiters
 

Right. It's safe to say the majority of us here understand the workings of delay boxes. I was more or less referencing that the grid doesn't do all the magic that people think it does. Maybe if it's paired with a race pack so you can mess with fuel curves on a carb engine. But then again, the EFI combos all have that capability and a million other options that I'm slowly learning about.

This probably isn't the thread for this opinion but oh well. Who cares about reatrictor plates or timing curves. You can drop at 900' feet for all I care. Lonnie, if you're reading any of these posts...take a closer look at the cars that are purposely built illegaly. Stick a magnet to a fender or wheel tub. See if it sticks. Look under the cars for wires and electronics that don't belong. Bring some integrity back to these classes.

Re: Throttle Limiters
 

Throttle limiters?? Hell! I'm looking at throttle openers!! LMAO!!

Re: Throttle Limiters
 

you guys need to watch big dollar bracket races final rounds on motormania tv. footbrake cars puting .010 packages together. it is about cutting a light and finish line racing. my friend who wins a lot puts over 200 runs on his car a year. 4 day race will be 30 runs sometimes when winning.

Re: Throttle Limiters
 

You are missing the point of this thread. This ties directly to the AHFS.

Re: Throttle Limiters
 

Many years ago, NHRA was looking at the wiring of the Idle Stop on Quadrajet carburetors. It appears some racers found a way to use it as a throttle limiter by using a toggle switch.
As I stated earlier, racers are creative and there are many ways to skin a cat. (Sorry Cat Lovers... :D )

Re: Throttle Limiters
 

Most of us understand that you are on a mission to un-ring the bell on the changes to the AHFS. The point you are missing is that the AHFS is of no concern to more than 80% of the racers because they never will trip the review triggers. And most of us understand that you are simply trying to recruit us to do your bidding to enhance your racing program. NHRA understands that as well. I'm sure they have read your posts about admonishing fellow Camaros racers for going too fast. You brought this on yourself. The changes will likely stay in place to the AHFS - which, by the way, is the same AHFS as we have raced under for 20 years. Stop whining and race your cars.

Re: Throttle Limiters
 

LOL!!

Re: Throttle Limiters
 

The only thing that I have an issue with is on a carburetor combo, the Racer is allowed 2 OEM type base gaskets. If you can find a base gasket with a smaller hole than the carb then go for it! I think the EFI restricter "plates" should go. They should have to adhere to the same 2 OEM gasket deal as the carb combos.
As far as "throttle stops", as long as they are mechanical and unable to be manipulated as the car is going down the track, I'm OK with them.

Re: Throttle Limiters
 

Considering the short travel length of the electric solenoid used for these anti run on throttle closing devices, if you are running quick enough to run index on less than 1/4 throttle opening of the primary side of a Quadrajet, I would have to think that is a very underfactored combination!:eek:

Re: Throttle Limiters
 

So it’s ok for a carb racer to run a smaller gasket than carb but if an EFI guy finds one it’s not ok. Just think they should be treated the same. Mike McMahan 2543 H/SA

Re: Throttle Limiters
 

THAT isn't what I said!

Re: Throttle Limiters
 

I’m just trying to understand. Isn’t the effect of what you said the same?

Re: Throttle Limiters
 

You're allowed 2 OEM type gaskets, IF you can find a gasket with a smaller hole in it then go for it! But it's gotta be a GASKET.
The EFI guys are making steel and aluminum plates and putting them between the throttle body and the manifold.

Re: Throttle Limiters
 

Why would you need 2 gaskets other than to put one on each side of the restrictor plate?

Re: Throttle Limiters
 

Some carbureted combos like a larger "plenum" under the carb. Some don't.

Re: Throttle Limiters
 

My post was made in jest, poking fun at all the fear and paranoia around the Grid. You can read more in the “Un-ring the Bell” thread.

Yes, there are illegal accessories available for it, but you can hook up illegal boxes to just about any ignition system if that’s what you want to do.

I understand that there could be a legitimate argument that any aftermarket ignition system does not belong on a Stock Eliminator car, but that’s a different argument.

Re: Throttle Limiters
 

Is this the selenoid that opened the throttle a little when the AC was turned on,to maintain idle speed?
I knew a racer years ago that had one of these on a stocker,but I think he was using it for a staging device. Flip a switch and it holds the throttle open for you.

Re: Throttle Limiters
 

. Darren.....do we have to run wide open?
Is Rich Christianson back????

Re: Throttle Limiters
 

This is what happens when you let it become a bracket race...
If it's a qualified field, then some of this will stop.
Qualify 64 (65 if you have to have the first round bye)
I think the quotas are too low...
Look at Gainsville, full in 6 minutes? Come on man...

Excuse me, I shall now go and don my kevlar under pants and fire suit... :eek:

Re: Throttle Limiters
 

Throttle limiters? Back in the day we were looking for throttle enhancers! Geez Louise. You guys need horsepower.

Re: Throttle Limiters
 

This might be a simple solution to small I D spacers and gaskets: seal them up and the racer can’t change spacers or gaskets during the race. The racer will be able to change to the “ fast “ carb or throttle body but the marked spacers and gaskets have to remain in place.

Just some thoughts

Re: Throttle Limiters
 

Larry, can we seal up the rear wheel nuts, I’ve seen a tenth between bias and radial tires. Let’s be fair on everything.

Re: Throttle Limiters
 

I think anybody can Re-Tire any time they want. Sometimes I would love to Re-Tire with a 10.5 on the cars but its not in the rules. A few years back we could run a 12" DOT tire but NHRA changed the rule for stock.

Re: Throttle Limiters
 

I think the same should apply in all the ways we pick these cars up, tires, oil, ice down, weight, fuel, restrictor plates and engine, trans, differential heaters. You can’t just pick out one thing you don’t like, unless you seal the whole car up after Qualifying. We all have a game we play.

Re: Throttle Limiters
 

Like it or not, very true!

Re: Throttle Limiters
 

If it is within the rules as written it’s ok.

Re: Throttle Limiters
 

Daren,

I am going to un plug one injector. All good!!

Once they start looking at the injector wiring I will un pin in one of 2 connectors available at the ECU or at the connector for the main harness to injector harness.

Game ON!
