Close to a meltdown !
Came close to melting the old polaris down today. A little bit of aluminum on on one of the plugs. Only 6 lbs of boost but pulls very hard, added a tooth and moved up 4 grams in weights and with the motor challenged a bit more the temp spiked to 1275 for a split second at WOT. Tops of the pistons still look fine but it definetly needs more fuel pressure as the motor is very lean. Excellent throttle response and the skiis don't come down until it runs out of gear. Takes about 2-3 seconds to reach this boost level I thought this sled was fun to ride when it was 155 hp with closer to 200 it should be a blast in the mountains (if it will live)
