[Fot] GT6 Balancer

[Scott Janzen]

I run an ATL damper originally fitted by Randy Lamp on my GT6.  I think the Goodparts unit is what I would go with if starting over today.
I do run all Jones Racing cogged belt drives for the crank, water pump and alternator.  Less drag, don’t have to worry about belt slippage or tension, very long life.

P.J.,
           I run an early stock type damper on my GT6 - the early damper has a smaller diameter pulley, for a slight underdrive.  It has served me well up to 8,000 RPM.
I have also built a customer 2.0L GT6 racing engine using the Goodparts harmonic damper kit - a very nice solution.  Highly recommended for any high rpm racing 2.5L. The 2.0L doesn't suffer as much with harmonics, but it's still a very nice upgrade for a 2.0L racing engine.  This kit includes an aluminum water pump.

Racetorations in the UK offers aluminum pump housings.  It's supposed to be a higher quality casting than the Bastuck offered by others.  I haven't had them side by side to confirm.

Hi guys.
  I'm wondering what racers are using for harmonic balancer /front pulley, on GT6? Also looking for an alloy water pump housing and pump.
                           Thanks. P.J.
