Nick Nicholas won his class of speedster/overhead valve powered. There was a thread of when you shift from low to high, this one is about 2500 rpm
I "phone" videotaped Nick on the dyno:
Here is a bad photo of the dyno results. 60 HP and 480 ft. lbs. of torque at 3190 RPM.
I thought he hit 72 hp on the dyno?
I think they said his peak hp was 74 but sustained hp was 60.
480 ft pounds of torque at 3190 is closer to 300 HP.
I'm going to watch this again!
The max torque 480 was at much lower rpm. The average torque was 92 and the average hp was 49.
Any pictures of his engine? What head & carb combination?
What was his time at the hill climb ? My information shows he did it in 11.959.
Frank, I think his best time was 11.03.
He is running a Fronty OHV.
If his peak HP was 74 and his max torque 480 ft. lbs., that means that he hit the max torque at something south of 1000 rpm's. That's about twice the torque of a turbo charged Cummins diesel.
Not the best pictures of the engine but you can see some of it.
One more not so good photo of the plumbing. This was a fun trip, took 263 pictures.
Here is Rob. Winner in the "K" class.
I got there late and could not dial in the hill. They would not let me do a test run. I had to run without a test drive of the hill and so got 12.311 without a test run. My carburetor lost its accelerator pump and the float was sunk in the bottom of the float bowl running too much raw gas because of the bumping on the 1600 mile trailer towing run with bouncing along the way. I would like a second chance to prove that flat heads can run well!
If he did 11.959 I may have very well dropped 0.352 seconds if allowed to tune the car.
I wonder what kind of a steering gear he has?
First I wouldn't trust the dyno info, there is way to much clutter in their data and they did not know the curve fit data, it just a number and couldn't be repeated with in 2% on the same day. We only got on pass and the dyno broke. I believe we made 120 ft lbs @ 2890 which works out to 66 hp before correction. Steering box is a Ross out of a Crosley. Best time was 11.017 which was after the hill climb and by a lighter driver or maybe a better driver. LOL!!!
Bring it on Frank you need to trim off a full second plus, OK that's just poking fun, it was good to see you and Humble Howard.
Nick lives at 5000 feet and we took apx 1.5 seconds off the time by adjusting the carb, clutch adjustment and tighten up a slipping low band.
