The engine was an out of chassis re build

Piston to liner height checked under spec

New liners pistons fitted ring gap checked

over boost? "standard fuel" runs 21.75 boost. spec is 21.6

Now pistons 2 & 4 cracked in 4100.00 Ks

it took up to 139.00 Ks to crack No5

How come pistons 1 3 6 are still good.......

If pistons were hitting the head i would not be asking questions

it would have dropped a valve by now. Keep guessing........Mark

Mike i will let you know how it goes. Should be good

That particular brand uses MAHLE brand, Google them up

very good brand. Certanly better than the other brand........Mark

Mahle earned their reputation in Formula Racing. They are certainly not a bad choice as far as pistons go. I have used their coated and un-coated pistons

in race engines and hot street engines, with good results.
