Default LTX Shootout Rules Clarification Needed

I posted this on the Shootout site, but it has seen very little traffic. I need an answer pretty quick, before I spend a bunch of money on parts.


"Non-stock style suspension permitted with 100 lb"

What gets a penalty?

1. Where do coil over shocks fit in this?

2. What about a solid rear conversion in a Corvette, etc. The NHRA allows a torque arm in Stock Eliminator.

3. What about a F-Body suspension in another car?

4. Anything that attaches to the stock mounting points?

Just asking, because this rule is really open to interpretation.

Thanks,

Daren

I really need that question and the others made clear by the organizers.

A lot of "stock style" components do not attach to the factory locations. The torque arm is one that usually has a relocated front mount.

The no wheelie bar rule has me looking hard at the suspension. Gump cuts low 1.3 sixty foot times with 402 RWHP. Add a few more HP and I may have an issue!

I am sure that all these rules seem dumb to you guys, but I want to bring something that is considered legal in September.

I wonder what it would be if I took the 250 lbs of lead out of the trunk? I hope the air is good in Rockingham in two weeks!

What gets a penalty?

1. Where do coil over shocks fit in this? Fronts ok with stock mounting points. Rears.....that would move the location of the springs so add the penalty.

2. What about a solid rear conversion in a Corvette, etc. The NHRA allows a torque arm in Stock Eliminator. Ok ...but add the weight penalty

3. What about a F-Body suspension in another car? Ok.....but add the penalty.

4. Anything that attaches to the stock mounting points? Correct

Your opinion is worth a lot. You have been racing in this arena a long time. My point in racing these events is to have fun. You can't have fun if you have everyone else pissed off!

If time and finances allow, I am planning to bring something pretty cool. I have self imposed limits that should put me in the middle of the pack again this year. I will point out that I wasn't close to making the most HP in Mod N/A last year (I wasn't even in the same ZIP code!!).

1. 3175 or 3275 race weight.

2. LT4 heads and intake.

3. Stock 3.48 crank.

4. Stock throttle body?

That's about all I am going to share, but I don't think that anyone really needs to worry!

In Modified: What about Pete Z bars, with the rear/upper tabs welded to the housing, instead of that big, heavy bolt-on deal of his? Rear narrowed 3" on each side & mini tubs?

Mini tubs ....ok.
Narrowed rear....ok.
Pete Z bars.........ok as long as torque arm is still on the car.

IMO the Pete-Z bars should not get a penalty. I have run them and they show no gain over a good torque arm. Really the torque arm works better once you figure it out. All they do is take the twist out of the rear. They are no where near as drastic as an aftermarket four link or ladder bars. The same would go for the Competition Engineering "lift bars.

I may agree with you. I researched the Pete Z bars heavily last night after I made the reply to Ed. It seems as if people that use them still keep the torque arm. I have to compare it to the guys that use a race drag sway bar which moves the mounting points on the body.

We will have a decision on it soon.

is this what you have Ed? Also is your torque are still on the car?

Tony, that is not mine, but pretty similar. I do still have the stock torque arm.
I didn't like the big heavy bolt-on rear mount Pete sells. The Stockers can't have anything welded on, Super Stock car can. I don't know that I can make that one, still need to check the 383" over and replace some parts I robbed from it to put my first SS engine together. Need to change gears too, it would never make it to the finish line with the gears this 350" needs. Lots of work and I have some health issues right not that I don't know will be cleared up by then (or ever). I'll try.

Thanks, Ed
