just having a bit of fun Mat.

There MUST be a difference, and in the case of 1/10th there is a marked difference between turbo and no turbo as far as outright HP is concerned. Any more info then that I will leave to the experts 8O

The turbo plugs seal better, so there is no loss of compression.
They dont use a copper o-ring like normal plugs to create a seal instead they have a chamfer on the end which seats into another chamfer in the head, "Turbo head".
This is why you cant use a normal plug in an engine with a turbo head and vise-versa.

The other reason a turbo plug and turbo head makes more power than a normal head/plug is that the combustion chamber is smoother as a result of the chamfered plug and seat in the head. The smoother combustion chamber promotes better squish in turn causing a smoother and more powerfull burn (power stroke).

The smoother combustion chamber also eliminates hot spots that can occur in a 'normal' combustion chamber, in extreme cases these hot spots can cause ignition of the air fuel mixture prior to the mixture reaching TDC.

You can get turbo heads for most engines now, I had a Sirio .27 that had a normal plug/head and I purchased a Turbo plug/head for it and the engine deffinately ran better, smoother and was alot crisper.

Hope that helps.
