do you think a stock a15 can handle 10psi boost without a head gasket shim? keeping in mind i have full programable wolf 3d injection

i am onto my second a14 running 12 psi. the first one lasted about one and a half years of punnishment which isnt to bad.
but for the next engine i will be downsizing down to 8 or 7 psi

i might be right then i dont drive it that hard.
i replaced the head gasket shim with a slightly thicker one and the power droped by heaps

it sounds like it should be alright then. i am going to build the expired engine i have to the tilt so we will eventually see how much boost an A series can handle.

is ur engine injected or blow through??????

its supercharged blow through fuel injection

have u had yours on the dyno.
i have not yet had mine but am expecting around 120hp mark.
12psi was a demon to drive in the wet..

that souunds about right
before i changed head gasket shims i was getting 112 rwkw but now it has droped to around 65 rwkw but stll pulling 270nms of torque

if the tune is good it should last a longtime

why would you drop compression to only run 10psi...

pointless in my opinion
