2010 D8 155 Clutching and track speed

[Ultrasauras]

Trying to help my buddy out with his new ride last week end in Revy it was only pulling 36-38 mph track speed on a climb.

Looks like the perferred set up it

62-42.46/.36 helix Is the Carl's one a special grind? or will a regular one work?
EPI 62 BB weights
stock springs
What will we see for track speed on a climb

or 58-38.46
EPI 64 bb
stock springs

Which is a better set up for 5-8000 ft

thanks

I have stock helix, 64g BB, and a 140-340 spring (I think) and adjusted deflection a bit. But I think he needs to gear it down, I went 19-42 from 20-41. I tried the Carl's helix with BB and MTX and I didn't like it. I do like more bottom and mid but I keep 8250-8350 RPM even in the wet snow we get in WA and low 40's mph on track speed. Good Luck

If you want to try the Carl's Helix I have one for sale, used once.
