I was wondering since my sled is only a 550, and can no way keep up with some of my buddies sleds (f7 Sno pro and 900) how can i make it faster for drag racing? I ordered studs and was told thats the #1 thing I could do but what else? Thanks, Matt

Clutch kits/re-gearing it.

I know it depends on the gears, but how much will that affect my top end, it only goes about 85 as it is?

**smallengineguy** · 12-30-2005, 11:04 AM

You can gear it to go faster on top, or to take off quicker. To do one, you'll lose the other...

Any ideas on how much I might lose if i gear it to be faster off the line?

everything is purportional (if thats how u spell it). the more u lower the gears for acceleration, the more topend you will lost. vise versa

Hope you've heard the old adage "There's no replacement for displacement"...............means that no 550 will keep up with a 700-900 sled. If there was a way, they would sell a million of 'em!

My goals not to keep up with them, but top maybe beat them in a drap race so I can shut 'em up, if you guys know what I mean.

letitsnow · 12-30-2005, 04:34 PM

maybe in a real short drag race, theres no way you can keep up past 50 or 60 mph.

Yeah your only advantage would be weight. But usually the extra power of a larger motor, easily overcomes the extra couple of pounds added by the engine.

Ok, thanks for the info. I guess i just deal with being in the back of the pack this year til I can afford a bigger sled next year.

that would be your best bet.

Just start taking steroids and working out. Than when guys start saying they can beat your sled, say you can kick their ass....... Than what are they gunna say, huh? NOTHING!

mattg1024 · 12-31-2005, 08:46 AM

It would be cheaper to buy a new sled then for me to try to get big on steriods with the 130 pound base i'm working with
