I want to take mine to 500, but Mark@Abbey is uncomfortable going that far on an unbuilt engine... guess I'll be saving for that then.
Am told blocks can cope with upto 600bhp before they start cracking..
I hope so I'm close
It's not the block its the rods that give up first - or so "they" say.
Seen it on other forums when I was looking at increasing power and my tuner hasn't recommended anything over 600 due to the block.. I'm running fully forged rods, pistons, bearings etc, so next thing to go would be the block... But i'd probably blow my diff before anything else.. Although I appeared to of stretched my timing chain so that's next issue to sort..
