Hi again.One fellow told me to just set up my HC's with my stock Helix.Said don't waste my money on a 50/36 or 50/38.What can I expect then?
 

Ouch, expect no top end and lots of dcs blinking because the end angle is waay too high.
 
you can adjust any weight to run the correct rpms all the way through, that doesnt mean it is the most efficient and or fastest setting.
lower finish angles work best with clickers, also large rollers, 15.6.

if you look around in here, mrviper has a great write up on helixes. also, check the tech section, there are a couple aritcles on clutching theory to understand the why and what your sled is doing with those parts you install.
 
This is what one local fellow told me and he runs an Apex.
Are you running the older 40 10....or the 2 speed 40 10........to get the rpms on the top just do it with the spring................and as far as top speed, its hard to get with out gearing up. Its not a helix that will give ya that..............I ran 216 at the ballicker with totally stock secondary. 51 43. a 47 is right in the middle. Possibly add or take out a little weight here or there and save your self some money! In your case i think i wpould add in the middle and run the top empty with the red spring. adjust accordingly after that.
 
Blue you will have no top end compared to a 50-38.I have tried many combo's.You don't have to listen to uis but the guys with the 50-36,50-38,and 50-40 fly.
I know if you stay with the stock helix you will be one here ccomplaining you have no top end.
 
i run both a 50/38 and 51/36 helix with my hc's and get good topend. i also have a 48/40 and find that i get a better topend with that but sacrifice some low end pull.. my motor is case ported by mr viper and perhaps it just likes to be loaded a bit harder than a stock motor. my 50/38 and 51/36 are both dalton helixes, and my 48/40 is an advant-edge. i have heard that the 48/40 advant-edge is actually more like a 48/42 so i dunno why i get better topend with that one but i do. i think it is alot of trial and error. my buddy has hc's on his stock viper and runs a 48/34 recut yamaha helix and he pulled 114.3 mph on radar last year, so the really shallow finish angle works awesome for him but maybe not in all cases. hope this helps. and not to jack your post but if anyone has any input on why i get better topend with my steeper finish angle helix that would be great. i thought i caught a post a while back forget by who but it said that ported and big bore motors prefer a little steeper finish when using hc's.
 
SNOWRULES> look up...LOOK WAY UP...above you.That is the man who said that...PRO116 ..about ported or big bore motors prefer steeper angles.LOL
 
blue who are you talking to that runs in the balllicker? and i hope that wasnt this year
cause i was there and there was no 216 unless he is turboed.
 
I think this is kinda getting beat to death isnt it? Bluemonster, I understand your trying to learn but how many times can you ask something about helixs and clutching??? You just went thru all this same questions and post with the 8dn 20's. Do some reading and go out and test,write notes down and youll soon give yourself a education on how clutching works. Keyboard tuning gets you no where.Theres plenty of information in the FAQ section pertaining to this. I am just giving you constructive criticism, not picking on you. Theres a couple more here doing the same thing, but you guys have to do some work on your own, and yes youll spend some money doing it, we all have. We give you guys set ups and then you question/argue as to its validity. I and others have spent the money and time to set them up, can only get you so close the rest is up to the sled owner, thats the real world.

The simple reason you can sometimes run slightly steeper finish with a big bore or a correctly ported 700 is it makes MORE HP!, More hp requires more weight! So,you can only fit about 7 grams in the tip of H/c's, there physically isnt anymore room to the side of the spiders pocket, so therefore to load the motor more you have to start going up in finish angle, this loads the motor now thru the secondary clutch as well. You need a shallow finish with H/C's to run good all the way thru, only with added hp will you be able to start going up in angle and gain speed. No one has a crystal ball to tell you exactly to what exact degree every part you need for your paticular sled, theres too many varibles, sled mods, rider weight, traction,chassis set up, no 2 are ever the same, so you must tune your set up to you!
 
hey thanks mr viper for answering my question. that was my problem was running 7.5 grams in the tip and still slightly over reving at 85-8600 with no room for more weight. decided to try my 48/40 for fun. had to take out some weight to get my rpm right but when i did i was pulling an extra 6-7mph on the speedo. i did however notice that i lost my holeshot. after about 150 feet though she picked back up and pulls like a freight train. i think now i'll have to go to something like a 51-50 start angle and 40-42 finish angle to get the holeshot back.
 
Jon, I would probally go back to your previous weight set up and just swap out differnt helixs till you find the sweet spot, a 50/40 is most likely where youll be.
 
Thanks for the input Don. sled seemed to work better all the way through with my previous weight setup. it just needed to be loaded a little more on top but i couldn't do it by adding weight. that clutch setup ran extremely cool as well, when using the 48/40 setup i found it produced alot more heat. i ended up blowing 2 belts my last lake runs of the season (was around plus 10 celcius out) with the 48/40 setup. i think just because of too much heat cause the motor was aligned just a weekend before, and i never had an issue using the other setup in the same temperatures.
 
I have a setup from Turck that runs a Dalton 51/37, I pulls like a frieght train. I have a hard time pulling it when it gets a little warm out though. At about -10 to 0 degrees it rocks. Just hate to pull a out little tip weight.
 
Super
That set up has won a lot of drag races & radar runs! I think u now have the only SRX set up like that. Lotsa time on that one & I even forgot how it is set up exactly so I can,t duplicate it!
 
superclean truk set up should be an excllent set up.I use to run a 50/36 dalton heix so I'm shure the set up was very similar.
