HPI Baja transmission gears

[DougStar]

Iv been looking @ the turtle racing quick diff trans case setup
Since this is my first walk down the hpi route this is all new to me. In the trans case we three gears the drive, idler and diff/ring gear. And you can get them in a few sizes now corect me ifim wrong....the number of teeth increase but the gear stays the same size. What are you lot running in your transmition?

i believe the do stay the same size, becuase then why would they sell it as it fits the stock case which the turtle case is based off of. also, im running a whole lot of CRAP in my transmission

I've got these in my truck. They either come with a 19T or 20T. The 19T is for the 5T and 20T for the 5B.

 

[DougStar]

19t speed 20t torque?

 

[Milo]

Other way round mate.
I've got the 19T to give more punch due to the weight. I use the pinion and spur to adjust for speed. 19/ 55.

 

[DougStar]

Right with you??
So you have them I your rigs tranny? All three? What ar you running for your spur and pinion?

The 19T is to compensate for the larger 5t/sc wheels

Fair enough that's the idle gear
We can still change the other two drive and ring

Yes I have all 3. I run a 19/ 55 in both buggy and truck. TR HD pinion and hostile spur gears.

Have you not considered the vertigo hex bell?

Have you not considered the vertigo hex bell?

I have but my clutch is non vented. I might get one in the future though.

Do you need a vented clutch ? Didnt think so surely it would fit ?

Do you need a vented clutch ? Didnt think so surely it would fit ?

Well, I wouldn’t need it for the hex because of the TR HD clutch bell and pinion are ok, but the clutch bell is solid. So I think my only problem could be heat build up, but so far so good I think.

The Vertigo systems have vented housings and bells, so for me that is the only benefit.

Maybe I might drill some holes in the housing to get air flow through it, but as I’ve said it’s yet to be an issue for me.
