Helix angles

[mynewuseddoo]

So I have a 38/44 helix in my cpc torsional secondary and I'm wondering about playing around with different helixes to fine tune a little more. If I drop the angles would it give me more top end track speed for climbing and quicker out of the hole response? Say going with a 36/42 helix for example. Or would I be looking for a wider spread like a 38/46?

Just looking for some insight as I am not as familiar with the clutching as I am with the rest of the turbo system.

Thanks

What elevation, I would think it would give a little more top end track speed, unless you are a little guy in which case it wont really matter. Just have to try it and see

7000-9000 feet and I'm about 225 plus gear. 10 psi boost if that helps

36/42 and 2 more grams in primary use big dog weights will give you more top end speed

I think my dealer is using 36/40 or 42 around 9-10000ft and it seems to work great for him, he is around 200lbs but I'm pretty sure thats how he sets up everyones sleds. Thats also not a torsional setup so there is a difference.

are most of you guys running straight cut helixes or progressive cuts ?? I am running a straight cut 44 with a cat orange secondary and it seams to work good. Now I am wondering if a 36/44 or a 36/48 will give me better bottom end response and quicker spooling...

Im running a 36/42 Im Thinking, Ill look at it tonight but is a CPC Secondary also with the Gen 2 torsional Setup. On a Cat M1000 Piped ,Attitude box, and lots of other upgrades and no problems with belts or too much heat in the clutching, Ill recheck when not at work for sure.

Turbo helix start low and and go up to load the turbo as it spools. N/A helix go the other way to hold rpm's in climbs as power levels off. I'd be surprized if you are running a 36/42 on a piped M100 and liking it. Are you sure it's not a 42/36?

Try a 36/48 or 36/44 and load your weights in the heal. What primary spring are you running right now? What gears are you running?

still think if your a over 200+lb rider and above 9000ft you want to be in that 42 and under on the finish.

I walk around at 165- 170 so I am defiantly not big. I am running mmsports heavy tip turbo weights as well at 7000 ft and under. So maybe that is why my straight 44 is working for me ...

I am running the CPC gold white primary 135-305 lb finish. I also run light tip CPC turbo mags for boondocking. I tried running them heavy in the tips last season to see the result and I didn't notice much on the top end, it did hurt my bottom end response quite a bit though. I lowered my gears from the stock 57/63 to 55/65 and gained about 5 mph on the top end while climbing. It also hits harder down low so I'm happy with the new gear set.

I was checking out the dalton website and I didn't see a 36/42 or a 36/40 helix for my CPC torsional secondary so I might have to call them and see if they can custom cut it for me. Its going to be a trial and error process I think.

I'm also changing out my 09 pipe for a 2010-2011 pipe with larger stinger and the speedwurx turbo Y pipe for better flow. If anyone knows of a used 2010-2011 m8 pipe that someone wants to get rid of, let me know please.
