More power!!!

Post by rdover »

I'm about to convert my TGB13 to run on unleaded an take the compression up a notch at the same time. I've been advised to skim 2mm off the head wich will release an extra 15%-20% extra power. This will allow the engine to best use the LPG which it normally runs on.

Any comments?

Have a machine shop put some harder valve seats in the head.

The CI head and the directly cut valve seats are not too resistant to torching. Since the head is coming off it makes sense to upgrade for possible future unleaded petrol use and the higher anticipated temps likely with a compression increase.

Thats why we always have an exchange head in stock for those wanting to stop pinking and detonation a symptom particularly present on the B30/ c303 series install.

Is 2mm the right amount to skim off? I'd hate to get it wrong and either miss out on a cheap power upgrade or go too far.

Silly question. Won't I need shorter pushrods?

I would not take anything off.

You are not going to notice the difference, other than you may get more "pinging" which the B30 is already prone to doing.

Just my two cents worth



By the way Dennis,

what did you think about the piston I sent you

Hmmm
Lots of conflicting opinions. I'm now REALLY unsure of what to do!
