We plan on meeting up on Sunday around Noon and anyone from here no matter the make of car you more then welcome to come. Hope to see some of you out there.

The only limitation is it is for 2wd drive cars only 4wd cars are welcome to come in and pay the special price and make an appointment for a future day.

Did anyone from here get their car dyno'd?

I went on Sunday and my '91 NSX, only mod = RM exhaust, showed 253.5 HP@8000 RPM, 193 ft-lbs torque@4700 RPM (4th gear runs).

The only thing that bothers me about the graphs is that torque = HP around 6300 RPM.

My son (aka my chief mechanic and darned fast driver in his own right) and I thought torque = HP @ 5252 RPM.

Could the numbers from the dyno be off?

(On another note, our Track Rat Miata measured about 115 HP peak (don't remember the RPM, don't have the printout in front of me), and the mixture, much as we suspected from previous dyno runs, goes WAY rich above 5000 RPM, so we're losing significant HP at the top end.

We're running a 1.6L ECU with a 1.8L engine swap, FWIW. Need to work on that. Time for a Megasquirt and an hour's worth of dyno time. But I digress.)

If any of you can explain why torque <> HP @ 5252 RPM I'm all ears.

One nice thing is that the torque curve was pretty darned flat 3000 - 7500 RPM. HP was nice and flat 7000 - 8200.

Tq and HP should cross at 5252 if they are on the same scale graphs. If your peak hp and Tq are not close to being the same, most dynos auto scale the graphs to allow a better presentation.
