Northeast Performance in Bow (Rte 3a 1 mile south of I89) has acquired a Dynojet 2 X 48 dyno. It was formerly at Martel Racing in Manchester. I got on today with the TOYLET and made 9 runs in 2 hours with 2 carb changes, 2 ignition settings, and several cam timings. The owner, Cullen Goduti was very responsive and helpful. I recommend them if anyone is as frustruated as I am getting dyno time in this area.
BTW, the 48 inch drum is above ground, so the car has to be raised about 5 feet. Running on the larger drum is inherently more acurate than the 24 inch in-floor models.
Get in touch with Cullen at CGoduti@aol.com or 603-717 7333.

Re: Good Dyno in SNH
Raised 5 feet? Is the car driven up some sort of ramps? Any pics?

Re: Good Dyno in SNH
Dan, what was the rate?
I've used KTR in Ayer, MA. They are $195/hr, with the air/fuel tool as well.

Re: Good Dyno in SNH
The car is driven onto a lift then raised the requisite height to the dyno level. You can see a picture of it on the Dynojet web site Model 248X.
Northeast charges $75 for 3 pulls, $100 per hour (customer tunes) or $125 per hour and they tune.
They have wide-band.
Data analyzed from last Friday's runs show scatter less than +/- 0.1%. Bias is negligible since drum position is digitized up front. Bias introduced by the engine tuner can be a problem. You must take time to stabilize oil and coolant temps at same/similar values for each run. I always run two back-back for the first runs. Always pick up 2% or so on the second run since oil temperature in engine and drive train has warmed up.
Patient running and careful post-test analysis of the data yields some fine incremental tuning results. I was doing a 4 variable test, and looking for improvements in the .5-2% range. I am satisfied.

Remember, a small gain in engine torque is worth as much as 2-3 times improvement in acceleration since it is engine torque minus aerodynamic drag torque that counts.

Re: Good Dyno in SNH
That all sounds so....complicated. Anything that makes you faster is worth the effort,though

Re: Good Dyno in SNH
Not really complicated. Just takes patience and decent post-processing.

Patience! Ah..there's my problem..
