clutching for 12-18lbs at sea level

[Need for Speed 2]

Guys I would like to get as much info on this as posible therer seems to be alot of different ideas or theries or end results can I get some ideas as to what helix angles and secondary springs most are running for power levels 280-340 hp

Forgive me for jumping in this thread but I would love some input here as well. Ran a s/c all last year and jumping up to a turbo. Need all the help I can get on clutching this thing.
Thanks Art

me three.jumping from 8lbs to 18-20 this year and think i will need a whole new set-up.i have a rear mount so would like the engagement as high as 5000-6000 rpm

I really like something close to an adant-edge 53/43 with a pink or white secondary spring if you can find one. 20/50 2 speed supertorquers in the primary. Hang on!

Like turk said 53/43 or I used a 54/42 in mine. I used that 54 to help me from just touching the rev limiter if my sled were to spin really bad off the line. If you find you are not hitting the limiter try a 52/42 and see how that works for you.

I ran the OSO spring
2 tungsten in the heel
2 washers mid
2-4 washers tip depending on boost

Obvisously tip weight influences RPM most.

2-speed Supertorquers work very well when it's time to turn up the boost.

Truth is there is no simple set up that will work it that much of a HP range.

In fact you must reclutch for every 10 HP.

Then you have Power Curves to deal with, I clutch a Rear Mount Completely different than a front mount, and a both different than a supercharger.

I use completely different Helixes for different riding conditions.

2 speed weights have they're place but they are not for everybody.

I am not going to give away the Farm but, Here are some simple guidlines that work.

Pick a front spring that will give the engagement RPM you like, then use an 80-100 lb spread.
Pick a rear spring and stick with it.
Adjust your shift RPM with your weights.
Pick a helix that will give you the back shift you like.
Helix is a Personal Descision for riding style.

I have used these weights in trail sleds; race sleds & top end radar run type sleds. If have used em in front mounts & rear mounts with great success. They can be tuned to work well in any sled with the proper set up. The guy setting em up just has to know what he is doing. They are very easy to tune & with the proper combination of springs & helix can be made to work in any sled or condition as probably any other weight out there. I just find the 2 speeds the easiest to get dialed in.

Exactly, why I said what I said.

What about a shockwave helix the ramps are ajustable, how are they holding up?
