Dyno Rules

The dyno competition will be broken down into 4 classes Street Stock, Modified, Pro Street, and Pro Modified.

Each class will follow the same rules as for the track class breakdowns. In addition to those rules, the following rules will apply on the dyno.

1) Use of NOS (nitrous oxide) prohibited.

2) Each participant gets 2 pulls to produce their max TQ and HP. The maximum numbers will be used. (Example: If the max HP is from pull #1 and max TQ from pull #2.)

3) If the dyno has a malfunction or if the car downshifts a 3rd pull will be allowed.

4) No tuning will be allowed between pulls.

5) Torque converter locking is allowed as long as the person does not change any other transmission or tuning settings during competition (locked for HP and unlocked for torque).

6) A HP spike will not be counted as your highest HP. We are trying to achieve true actual performance numbers. Knowing how to manipulate a dyno and release the throttle at the right moment to achieve a HP spike will not be counted.

Looks like a nice set of rules

[SilverCasket]

Looks good again. Can't wait to see you all again!

[Slysc]

Seems like we should be able to have a modified camshaft for the modified class? Why the restriction to use only a stock cam?

[kuhnga]

Dan,
I would say it is the same as saying stock Long block, since most would not modify their cam w/o doing there heads also. Any other internal mod will not make a noticable HP difference.

You are pro mod all day long Dan so quit trying.

[MercsSC]

mod class or soon to be the Nitrous Oxide class ..says stock cam.. doesn't say anything about reginding ...stock cam profile

also is a bhj harmonic blancer allowed in street stock ? not stock and it's not a pulley and between the heads and oil pan ....ok pushing it here

how fast can you go... before you need to have a cage or go home ?

see you all there ....dave

[Slysc]

Would a regrind be considered a "stock cam"?
Also, in Mod class it would be legal to run H-beam rods and custom pistons modified heads, who in their right mind would do all that and keep a stock cam?
Gary, I'm gonna keep trying for Mod class so I don't have to run against you whipple guys!

[V6Sprout]

how are you gonna enforce these rules? Are you gonna tear down each motor that wins each class to inspect? I mean someone coudl say they have a stock cam or stocklongblock or whatever, how is anyone to know? Mods on motors seems to be a big secret over here you never know what people have. Well at least cam specs are. NOt saying people are cheaters but if it gives someone the edge to win saying htey have a stock this or that and they don't how are you gonna enforce that, just curious.


I like the setup you guys have though, lots of different classes for people to enter, nice variety, makes me wish I had more then just the SC motor hahaha

[XR7 Dave]

Thanks Jamie!

As for the cam, it is pretty simple really. If the car won't pull stock vacuum it will get the option to move up or go bracket. We don't plan to do motor teardowns to verify mods. We will bring a real vacuum gauge to test motors.

Oh, and a BHJ balancer is considered a maintenance item, not a performance modification.

Dan, I don't see too many 3.8's capable of anything faster than last year. Remember that true 3.8's have run 11.9's already and none of those individuals are standing in line for a Whipple at this point. I think that low 12's are going to be needed to be competitive in the Pro Street category this year regardless.

I'm thinking that the Pro ET class is the place to be this year. We went over many different scenarios for Mod class rules. The problem is that if you look at all of us in the mod class last year, we were a real motley bunch. We really had nothing in common other than we ran about the same ET's. Some had front mounts, some didnt. Some had forged internals, some didn't. Some were full weight, some were not. See what I mean? From here out we are looking for the real "tough guys" to run in the Pro Mod class. Let's face it. If we don't encourage some people to go fast with the resources to do so, the bar will never be raised.

We are looking into the possibility of having the Pro ET class run on a pro tree as well. It will be a lot of fun.

[David Neibert]

I'm probably going to race in the Pro Mod class, so I can use nitrous with a non-stock cam.

It should also be mentioned that the track we are racing on this year is an IHRA track and I believe you can run as quick as 11.500 without a rollbar and 5 point harness.

[super red91]

Nitrous allowed based on the following. *Vehicle must meet all requirements of Street Stock class with the exception of the use of nitrous.*
I plan on running in the mod class ,so since I dont have converters, I will not be able to run nitrous?

Are m/t e.t. streets or BFG drag radials allowed in the mod class?

Also since my battery is in the trunk, will I need to have a shut off switch?

Your car appears to be legal in Mod Class if you run drag radials and no nitrous. Converters are not required in Mod Class. If you want to use your nitrous and/or ET Streets, you will be in the Pro Street class. With a trunk mounted battery you will have to add an external cut-off switch regardless of class.

[super red91]

Does this mean im gonna have to make a hole in my bumper? Where is a good place to mount this switch?

[XR7 Dave]

No, you don't have to cut bumper or lights. A couple of people have mounted a switch under the car and had a handle poking out of the vents in the back that can be taken off for street use.

Another option is to make plate that fits in the location of the stock taillight. You can remove the tailight at the track and pop the switch in. Both tailights are not required to be working at the track, only one. I've done this and it works pretty well not to mention it requires no mods to the car at all.

Nice try Dave- It should also be mentioned that in Ohio you can marry your sister, but we encourage everyone to use the National rules and not find loop holes.

Alot of fun for who? Dont get confussed with Pro ET and Pro drivers- WE aint got no
