VIPR PWR said:I've never dealt with Dyno's.....but it sounds like your saying that you can get the HP & tork readings from just running down the track and doing the math----is that correct ? If so then why have the vehicle put on a dyno ? Or am I missing something , I just don't know but am willing to learn
Dynos are a tuning tool. You can monitor timing and A/F ratios, make changes, watch the results, change parts, tune for a certain load for fuel economy, etc; etc.. If you have enough time between cooldowns etc; you can accomplish quite a bit.
To a lesser degree, they are also a good place to find pressure leaks, etc. and are generally safer than looking for leaks when you are driving down the road at 100+ m.p.h.
You can't race a dyno so, in the end, your efforts will be more or less proven at the track.
It takes a certain amount of torque and horsepower (torque measured over time) to move a certain amount of weight from a dead stop to a certain speed. Currently, you will require around 6000 horsepower to move a Top Fueler down a 1/4 mile to a 320+ m.p.h. trap speed.
Comparing dyno numbers can open a can of worms.
If someone tells you their SRT10 makes 600+ wheel horsepower and they are only running 100 m.p.h. at the track, something is wrong with their numbers.
There are several software solutions for determining how much power you would need to accomplish your goals and they are quite accurate.
