[Fot] Opinion needed on GT6 pistons

[Spitfire Racing]

I did an engine rebuild for a GT-6 owner on his occasional track car and
against my recommendation he wanted the cheaper option of County pistons. I
had suggested using either J&E; Aries or Venolia forged pistons but he
didn't want to "spend that much". I found their weights to be less uniform
but in all honesty to the best of my awareness the engine is still running.
These are made in China and given how nervous they made me, I don't think I
would do another build using them. The builder is always held responsible
for any failure regardless of cause. When I build a Spitfire engine using
proper forged pistons we dyno test at 7800. I would be nervous doing that
with County pistons.

 

I will say I admit to having general misgivings about anything made in China
but that's based on experience. Why risk your reputation and the expense of
a total build by using cheap pistons. It's a false economy. I dreaded every
time the phone rang for a month after delivering the car, but in this
instance they seemingly met the requirement. It takes years to build a
reputation but it can be lost in mere minutes.

 

County pistons may work for street car applications but are a risky choice
for the rigors of racing. Spinning a bearing indicates either poor
clearances or an oiling deficiency. A proper rebuild should check and
correct only everything! Don't assume the one problem you find is the only
problem. Shortcuts predictably end up in expensive disaster.

I'll step off the soap box now!

Choose wisely!

I'm rebuilding and engine for a fellow club member and need to get an
opinion on County pistons.

The last " rebuild" only lasted minutes on track until it spun a bearing.
The pistons were new

for the last build. Since I have no experience with the County brand I'd
like to know from the collective 

if they are descent racing pistons.

Thanks as always,
