From what i here stock gearing is to high for stock sled, Can i change just my top gear from 23/37 to 21/37 in a 1999 srx will it fit with stock chain and what top end will i get around ?

OR should i go 23/40 and will it fit stock chain and what top end?, dont have cash to get 2 gears and chain wife will kill me lol, so wilL one of these set ups work for me or should i wait?

ps: LOOKING FOR MORE ACCELERATION ON A SMALL BUDGET

OK so with 23/39 what speed will i see on stock srx 700 and will i see a noticable difference in acceleration, also what would be a good allaround helix for my stock srx

When you gear down (numerically higher) you get more acceleration... and opposite for gearing up.. less acceleration. more top end mph. You cant really put a mph on it many variables in a sled.. with clutching, weight, trail condition... Still plenty fast for trails though.. =)
 
i race on lakes most the time and it is not plowed just packed from sleds raceing there, so most of the time it is lose snow, so will i see a increase in speed in 2500 feet gearing down because it is geared to fast to start with, i dont race in perfict conditions but would like to see 105-110 if i can more often. also should i change my helix and witch helix will work for me sled is stock ?
 
I wouldnt spend your money on gearing i dont think your gona get anymore on top then with a 23/37 spend more time on clutching. Do a search on here there is lots of posts on this

whats your setup know??

MY Sled is stock with MBRP can, 144 studs and 4800 engagement spring. I am 195 pounds, so what helix would help me out?
 
I know you did not ask about this, but you are losing mph with that MBRP can. I had one on my 98 SRX and made it a total pooch on top end! Sold that can after one weekend of use.
 
take off the mbrp can stock is supposed to be better

Get yourself a 51/43 rx1 helix they can be aquired fairly cheap on here.

If you do a search on 51/43 srx you should find alot of info
 
I put a 51-40 helix on mine and added weight to the stock weights and also geared down one tooth on the top and it woke up my sled. I still pulled 116mph on gps. I am know gearing even lower and got the primary machined for overdrive to get to my top end even faster.
 
Ok so i am thinking to try a 51/43 rx1 helix and 23/39 gears will this be a good upgrade over stock in 2000 feet race. I just want to keep up to those F7s and 800s out there if I can.
