Only if you run heavy.

Or, a driver chooses to particpate in a class with stable rules designed around low cost.

It doesn't matter what the HP/TQ number is as long as it's repeatable and that's where the rub seems to be now.

What if I paid $XX on a weekend to have a black box run during warm-up or qual for my "weekend dyno." If I get randomed for a race and break out, I'm DQ'd ~ prevents sandbagging, is cheap and (hopefully) repeatable.

I hate these dynos. I'll bet money that the variation between like dynos is greater than we think. I also do not like the 9.5 lb/Hp and 9.0 lb/tq rule because it really puts the mod motors behind the 8-ball: high reving (and thus Hp) with crappy torque. I love the GPS puck idea. We could buy a few, determine each cars Hp at the begining of the season and then do random checks, Oh yea, for no cost. Hell, I'll buy the pucks. Lets do it. FMR

Man we've come a long way from "I'll give up the dyno and go to CMC2 over my dead body."

Sounds like we need a round or two of KL or PBR.

2 things:
1- The dyno deal has worked w/ very few issues over the last 10+ years. I understand and agree w/ all that has been said regarding them, but you can't argue that the current process is totally useless.

2- The MaxQ Data logger (or a device like it) is the future. It will take time to be sure we don't move to it prematurely and cause a bigger problem.

It has worked pretty well for the past few years, but I think the apprehension is new because we haven't seen random pulls since 2006.

After Al/Rob's issue at Nationals, I think it makes most pretty nervous to know we are tied to relying on a potentially unreliable tool.

I would not be all that worried if each one of us used the same dyno for every pull but going from dyno to dyno in different parts of the country and the possibility of a dyno or two that are not in tip top condition is a mess. I doubt my car would make too much power on any of them assuming my numbers are the same as the last motor.

Did we not learn enough from using the pucks last year to go to them in place of the dyno? You can leave a puck on my car all the time for all I care.

The only reason it's "worked" is because its been the only tool and standard.

Those pucks might come with their own "drama", but at least its repeatable and standardized drama.

For me ... that's what I want to see. A standardized way to measure ALL cars at the same place and point in time.

Nationals can do it with a dyno ... it's there and its repeatble. Regionally, it's just not possible.

To ensure parity, we all need to use the same measuring stick, not just the same type measuring stick.

Who's got good data that says the pucks are repeatable, standardized, or closely related to how much power (or torque) the car is putting down???

I think they have their own issues that are bigger than the dyno stuff. My belief is that they can be used as an indicator to determine who might need to be sent to the dyno for a closer look...

I think the dyno is a slightly flawed but overall good tool for the series to use.

More specifically on your statement, most (all?) of the cars that had issues with the dyno at Nationals had been on those exact rollers a couple of days before...
