bigger upper gear

[turboapc]

Hi!
if the info is all ready here somewhere, sorry for that.
Can't find it

Is there any other model which have same upper sprocket in chaincase than phazer?

i have 151" with clutch/helix kit and 17/41 gearing
Now that i have tuned chassis very good i think i can put one teeth bigger upper gear..

do i have buy it from dealer?
or is it some other models also, so i can buy it used

Are you still running a stock secondary clutch or have you upgraded to the modern Vmax style? Reason I ask is because upgrading to the Vmax secondary allows more overdrive so you can run more speed without swapping gears. Another added benefit is better backshift which is nice with a big track like that. I'm sure someone around here should have a 18t laying around, many short track guys drop to 17t. I run a 18t in my MTX and I run out of clutch at 83mph on speedo with a Vmax secondary, 88mph with a 19t. Stock secondary was only 75 with a 17t and 83 with a 19t.

i get only about 68 mp/h real gps speed
I believe i 8 teeth "track sprockets" . one teeth smaller anyways. (i did not build sled )

so what model year Vmax secondary i start to looking for?
And does the helix fit from my phazer original secondary to Vmax ? or is Vmax secondary very good as it is?

My downshifting is now very good. Almost never had to use brake. even if i drive very fast at trails

8 tooth sprocket is stock on the MTX, which I have and 68 GPS sound dead on for a 17t. 18t will allow ~4mph more before your out of clutch and 19t ~8mph more. I ran a 19t + Vmax secondary and could hit 82mph GPS under ideal conditions which showed 91 on the speedo but I only have a 1.5" 144 on my sled. With a 18t+Vmax It will run 78gps/87speedo when the clutches are shifted out and will still creep up higher if I let the RPMs climb. 95-96 VMAX 500/600 clutches are a direct bolt on with a spacer + longer bolt

I believe this is original FX and gearing are now 17/41

Way it behaves does not feel like underpower or dead. Very quick to top speed

it goes ideal condition about 125 kmh (meter, not gps)
i know meter lies about 10 km/h at top so it goes 115 an ideal condition and i believe it is 71 mp/h

gonna try that vmax secondary...
I have 1" 151 camoplast challencer..

i also read somewhere that you can machining the secondary so it wide open moore.
can someone tell more of that..
Gonna try to mark clutch plate with marker and see how up belt goes on first variator when driving..

I would definitely look into more overdrive before gearing up, especially with the Phazer's limited HP. Every tooth bigger is going to cut 5% of your torque to the track and with a 151 you don't to be doing that if you can avoid it. That's the reason dropped back to a 18t, decided to give up that extra 2-3mph on long pulls for more grunt while boondocking. I've run the 17t 18t and 19t and the 18t works best with my 144x1.5" freeride. If I ever get around to installing the Challanger 156x2 I have then the 17t is going back in.
