910 PAR

[kej]

I think any of the big bores based off the 800/900 cat twin were some of the highest torque motors ever.
They ripped in a 550+lb 1m dinosaur.

This is what I wanted. 900 Cat torque. Over 100 ftlbs from 5500 to 7200. I looked into it last year before I even decided to get the Pro.

It was the 173hp 117 ftlbs at 7950 that got my dreams going into the 910 motor. Way less work and way less weight. Worth the extra dollars anyday.
I was even talking with the builder about Lectrons and IQR ignition to save some more big weight (no oil infection, electric fuel pump, 'putor, wiring, sensors, lights, valve soleniods and on,,,) because really my elevation range is 5500 to 7000 for 95 percent of my time.

Worked back when and would work today. My goal was 380 lbs empty with 150 hp 110 ftlbs from 6000 to 7500. Sounds like dependable fun to me with an adjustable, leatherman and plug wrench in the tool pouch.

If my sled is running 147 hp im riding with a bunch of 115 hp stock sleds.
Track speed is around 44 mph
In a deep hard pull

I'm seeing 52 mph in a deep long pull on my ported 800 with a extreme lite 162 track at 3-6k pulling 66 g bellybusters
