44-34 helix on an m7

[slomo]

just wondering i have a 10.4 secondary and run a stock 36 helix but would the 44-34 give me more pull down low and keep my engine a little less loaded up on a long pull? as it starts to sack out after a real long pull,i.m running 67.5 wieghts
yellow primary and orange secondary with a shift assist,just want to know if this helix will help

I'd say, it depends on whose helix...but...I didn't like the AC 42/36, 'cause it was too abrupt a transistion when boondocking. I didn't like the BDX 46/36 progresive 'cause it was too much helix for my primary setup/secondary spring when climbing, but it was very quick on the flats. I would say, if it was progressive to 34, and all the transition to the flatter angle was before trackspeed hits 40mph, then you'd be ok, but nobody makes this helix, and all you gain is holeshot anyway, and I don't dragrace anymore anyway.

thanks for the info,it was a dalton 44-34 helix and the sled shop was
recommending it and i figured i'd ask around before picking one up as what works on his sled might not work on others thanks again

There is nothing wrong with that helix although I ended up running the dalton 45.38/36 on my 2006 m7. It worked better thru the shift sequence.

The orange is too much spring for that helix IMO. And when you say "on a lonh pull", are you refering to a climb?If so, then with a 44/34 you will be at something steeper than 36 while climbing, and will likely show even more fade or less RPM. IMO keep the 36 and play with primary spring...like a 140/300ish and go with LESS secondary spring. This worked well for me anyway-
