Finished a week of riding in Idaho and Montana high country. Worked a few more bugs out of my 1998 custom SRX. Other sleds incuded 3 Yami turbos, new 700 Polaris and 1000 Acat, and a nitrous Polaris and SkiDoo. Make no mistake, while its fun to make an old sled work well enough to play with the new ones, new sleds have come a long way since 1998. And if there was ever any doubt about the performance value of the turbo charger on a 4 stroke......holy chit. Here's a plug for the Turbo guys from Mercury Service. They brought a new Apex, an older 4 cyl and a new Phaser, all rear turbo'd. We were comparing track speeds during long climbs on the back side of Jefferson. The best 2 stroke spin speed was around 50 mph. The Apex was 82 mph with low boost. Unbelievable exhaust sound and you have never seen a sled hold the skis up while climbing like these turbos.
My SRX engine has been ported and the pipes are coated. Using the 10 series weights that came in the mountain viper. It wants to spin at 8400-8500 rpm and feels like its making good power, although I would appreciate some advice on what RPM I should run it at. My spin speed is 48 mph during long climbs. I found a wiring rub on the harness after it started to shut down at exactly the worst times. Had to cut the harness where it heads down under the motor. I have no dash guages so no matter but my digatron quit, and it is wired to the blue headlight wire found in the handlebar harness. I will take some wire with me on the next trip and replace the harness if I have to but would rather pick up 12 volts somewhere else for the digatron. Does anyone know what wire of the set running under the motor will give me 12v? Thanks in advance. I included a few pics my SRX and the Mercury Service turbos.
