S2 GEARING

[Wacker1]

Hi all,

I was running an LRP Vector Bonded 6.5T Motor on an 81 Spur Gear & a 22 Pinion, which seemed to work well.
I've recently upgraded to the NEW Orion 2008 Spec Vortex Sintered 6.5T Motor, which I tried my existing 81/22 Gearing, but seemed to rev-out early on the main straight of Tracks. I managed to find a Team Orion Gear Ratio Chart(eventhough I think it was for the Ver1 Motors), which said I should be on a 81,19........I ended up trying this but found it was even worse, as it was far too punchy & had nothing on the straights. I have been running on a 81/23 ever since, which seems to have improved it slightly, but I feel that its still revving out too early, I just wondered if anyone else out there is having difficulties on getting the Gearing right with their 2008 Vortex 6.5T Motor? I was tempted to try a 24 Pinion.

Cheers

24/81 on a 7.5 sintered in X6 which runs the same internal as the S2 I believe

sintered can be geared up, stick it on 24 and see how it goes

Novak 6.5L on a 23/81
Works well

I ran 6.5 sintered on 22/81 in the X6, that was great.

Hi Josh,

Was your 6.5T Sintered an Orion Vortex?

From experience of using the Vortex in Touring Cars as well, they always seem to be Geared a fair bit different to any other make of Motor.......I dont know why? They are an awesome Motor when Geared right though :-)

gear up... i've found that gearing the motors higher results in getting the power down smoother, making the car easier to drive, and faster over a run. try 24/25 pinion

Hi all,

Does anyone know what would be the best gearing for an Orion Vortex(2008 Spec) 5.5T Motor in an S2?

81 Spur Gear/? Pinion
