Turbo gearing disscussion

[Vertical-Extreme]

So with all the chatter about clutching gearing and track speed I thought it would be a good idea to have a turbo gearing thread.
List what you have for a turbo system , boost levels, track length and type, and gearing, Elevation and riding style.
Mine:
Turbo: M8 race gas custom turbo with pure logic fuel control
Boost: 12-14
Track: 162 power claw
Gearing: bdx 60/60
Elevation: 4500-6500 ft normally up to 10,000 couple times a year
Riding style: riding more trees and "slower" type stuff all the time

I think the 60/60's are fast for the riding I have been doing lately but I still like to hit Revy in the spring for some chute climbing

M1000rg 16-18psi. ce174 2.5. 98g weights running 60/60. like it climbing does not seem to be an issue boondocking. Did add a custom mount on base of motor and clamp it forward to sway bar tube to keep primary in place.

[Jeff K]

Type: M8 CPC stage 2 turbo
Boost: 6-10 psi depending on elevation/fuel
Track: 153" PowerClaw
Gearing: 54/66 inside a diamond lite drive
Elevation: 3000 - 8000 ft
Riding style: boondocking/technical terrain 70%, climbing 30%

Noticed a big improvement in clutch temps and track speed when gearing down. The sled is so much more fun to ride. Very happy with this setup for my riding style.

Back up top. I swapped my 60/60 for 57/63's on the weekend. I also swapped the p claw for a 2.5 camo extreme. I will report when I get a mile or so on
