Best Chassis Dyno

[WLDWST]

I need some board input. Who makes the absolute best chassis dyno, in terms of quality and ease of use. Also cost of maintainence and prices for rack time? Would like to hear from those with some ownership experience. :smile:

There a few other type.

There is a slick set up that Otto used to have. Yu would unbolt the rear tires and bolt up the dyno meters to the axle. Maybe he can chime here and tell us more about it. I know you can load the motor down big time with this set up.

Not worth a crap above 600hp, simply can not hold the power.

I own a Dynojet inertia dyno. I have had it for about 4 years now and I have had to replace 1 solenoid for the brake, and adjust the brake. I replaced the o2 sensor for my wideband one time as well. I have made at least 15,000 pulls with it. The best thing about the Dynojet is that it is VERY repeatable and maintains its accuracy.Tuning on a dyno relies heavily on the operator.You have to be familiar your machine and know how to set the fuel curve to be accurate on the track as compared to your simulated conditions on the dyno.

Mustang MD-1750 dual eddy current 250MPH, 2000HP I liked mine very much, much better at tuning than the Dynojet IMO

I researched chassis dynos for about a year and a half. The very BEST chassis dyno for a turbo/supercharged car is the Superflow chassis dyno with dual eddy current AND water brake. There are only a handfull of shops with them. Inertia dynos CALCULATE horsepower. Water brake dynos MEASURE horsepower. (I'm being OVERLY simplistic here) Dynojet is the standard that most guys go by, though. It really depends on what you want to do with your dyno. My findings, after talking with many, many dyno operators across the country, is that alone they rarely make big money. They are a tool that lets you sell other services to make real money. A torque wrench really doesn't make you money,either, but you MUST have one to build an engine. IF most people in your area have a Dynojet (a FINE peice of equipment, mind you) and you purchase some other brand, then there will always be the ignorant masses that will go to the dyno that reads the highest. (Bragging rights) What is your intended use of the dyno? Are you using it in a full service performance shop, or are you looking into opening a dyno "only" shop? I'm sure Bill can give a better, real life testimony to the uses/profits of his dyno. For the money, I think that Dynojet is the best bang for the buck. When I was looking into purchasing one a few years ago, it would have cost me over $90,000 to get a Superflow Chassis dyno (with water brake and air starter option-so I could dyno sprint cars) up and running in the shop (in ground).

The main reason I bought my dyno was to keep me from running up and down public highways at speeds far greater than reasonable. I no longer wish to endanger myself, others or risk the chance of wrecking a customers car for tuning/troubleshooting purposes. A dyno is only as good as the operator, the horsepower numbers (whether they are high or low) are used only as a guideline to determine if changes made to a vehicle increase or decrease performance. I generally only use it for "in house" jobs, we very seldom take walk ins or schedule appointments to give customers a HP number. It is simply not worth it from a financial standpoint.

Has anyone priced a Dyno Jet with the higher HP capacity? I think there AWD "cadilac" model is about 80K right?

I have done some research into this and agree with Bill in the fact that I don't think anyone will get rich off of one. I can't see how to run a true performance shop without one....
