Where is there a dyno (preferably dynojet)in the central Va area, and how much is dyno time? I want to re dyno my Maxima. I dynoed it at the Extreme Nationals on a Mustang dyno and got 170.5 hp and 348.8 ft-lbs of torque. I was told by the people running the dyno that there was a 25% loss for hp, which seemed about right, but could get no explanation about the torque. Their dyno also gave no corresponding engine speed.

 

Mustang dynos blow. Find yourself a shop with a Dynojet 248C and actually find out what your car makes.


There may be one soon in Central that i know of..thats TBD though.

 

170 hp and 348 trq

 

If you're looking for big numbers, use the dynojet. If you're looking to tune your car, use the Mustang dyno. Which would you rather do?

 

i think NU IMAGE has one....pm gtracer2b ...he works there....

 

This car will be bolt on only, and I want to get a baseline, and an ater mod number, just so I know.
BTW, could you explain the reason they give different numbers?

 

Yeah, that's what I said.....

 

that doesnt sound right but o well if it is the trq is good

 

No way that carhas that much trq at the wheels. If 1st and second would be usless under hard accleration.

 

The Mustang dyno places more of a real world load on the car using an inertia weight along with a computer controlled magnetic current that places a drag on the roller. The drag simulates real-world driving conditions, which alows you to tune to more accurate spark/fuel curves.

The dynojet is really nothing more than a 2 1/2 ton drum that creates an inertia load on the car. The reason it doesn't work as well as the Mustang dyno is because once you get the drum rolling, it doesn't take as much power to keep it going, in turn, giving you inflated power figures versus the Mustang dyno.

Basically...tune the car on a Mustang dyno and then go dyno on a dynojet so you'll have #'s to show off on the net
