I have a 98 mach with stock engine.

Primary 286 ramps
16.6g pins (solid stock)
130-200 spring (blue orange)

Secondary beige spring
50 degree helix
19lbs preload

Gearing 26-43

I want to improve this setup for 1200'-1500' lake drags and aggressive trail riding on twisty trails where your on and off the gas alot.

Right now on hard ice doesnt seem to bad,,, but with any loose snow on the lake getting alot of belt slippage.Never seem to get much of a holeshot.

I have read alot of forums on here and thinkng that i need the following changes.

230-380 primaryspring
pins at appox 19g
ramps are ok I think

secondary 20-22lbs
Is this helix ok??

gearing to 24-43

any suggestions would be greatly appreciated as it would save me alot of time and money !!!

Or would i be better off to purchase a kit throught cudney or somewhere??

Also would i see much improvement in switching to the 99 style pipes??

Thanks for any feedback

Every sled is a little different but the setup you mentioned should work a lot better than your stock setup. My 98 got 118 mph out of the box and was noticeably slower after the updates (it wouldn't pull as hard and I could only get 110 out of it after that). The first thing I did was get rid of the blue orange spring in favour of a 230-320 and added heavier pins (I found this spring was too soft and the engagement was too low for a decent holeshot). I also tried a 200-350 with good results but preferred the 230-320 so switched it back (I like my engagement around 4500 rpm). FWIW my setup is posted under the "how to slow down the shiftout of clutches" post. It seems to work pretty well except for when the snow is too loose and I get caught in too tall of a gear too fast (I'm getting some belt slip in the bottom of the secondary under these conditions similiar to you).

24 or 25 /43 gears is good , try on clicker 3 but go down if possible to run 8200-8300 stk pipes or what feels best.

Now this is what I find funny........

118 mph in 5 miles or 1000'

Now if I got 5 miles I bet I can break 200mph easy

Do you think you can break 118 mph in 1000' on radar?
