Had good luck with STM torsional conversion on turbos. The secondary spring is inconsistent stock in all sleds I’ve seen. Going to use conversion in riot and some other 800s I have to work on.

They are empty at 70 grams and I added 4.4 grams of weights to them. Stock primary spring (reverse likes them much better) 74.4 grams. Revving to 7950-8050. Pulls bear-like now. Mine is stock other than clutch spring changes. I have the Dalton Orange Black 175/245 secondary spring, I'm going to try as well.
Ever try the Dalton 175/245 ? ?

Haven't got there yet. If you were drag racing yes. In theory your top end will suffer.

Ive been doing this. Sled performs well but the reverse is useless. You have to be on flat ground with minimal pretension on torsional. Or it slips and will ruin a belt.

Only option is to run bikemans huge orange torsional spring but i think you lose performance going super stiff again

anyone find a "better" helix angle to run, vs the 64/49 stocker? anything really waking these up, that we should be looking at? for record 18 xf high country 141 8000, 19-50 gears, dalton 76.2 gram (70 base weight) 85-255 primary, stock belt, stock, secondary.

thoughts on a straight 49 or straight 48 helix? have the dalton orange/white 160-220 driven spring on way. Ski

So with my Daltons set at 72.2 grams and my orange/white Dalton secondary spring and a belt with 1200 miles on it, my 2019 CTEC 8 Ltd hit 105 MPH yesterday on the lake. It was cold and I had the stock windshield on it. This thing rips.

Try the 2020 helix. It has a lot less starting angle and the same finish.

for your sled i would go with the 170/240 sec spring, the 64/49 ihelix is a straight 49 after .20 shift... So @ 20mph, change your primary spring to more initial weight ...say a 120-140.
