what do you mean by normal comp? standard comp? if so you worked out what comp you going to have with the head gasket? and the rest?

yes, its standard compression.
what do you mean by the rest?
p/s : i do not know how to work out the compression thingy...



thanks

if your doing it at a good engine builder he will be able to work it out the compression ratio for you.

you dont calculate the comp ration by the pistons only. head work/ scimming of the block and head / head gasket thicknes will all make a difference in the comp ratio bud..

oh ok,

so shud i get my engine builder to do the engine first and do a compression test before i determine how much boost i can use?

wy 75mm pistons? id go for 74.5mm tbh will leave more meat on the bores & ud be safe if anything goes wrong & you would have to rebore..

boost is very dependant on how good ur fuel setup is.. not to mention if u have a modified combustion chamber (ie no rough edges) & what sort of fuel you will be running.. as long as there is no detonation you are safe to run as much as ur setup can give u :)

thanks kon,

i was thinking -> the bigger the better for high hp. didnt thought bout the block becoming thinner.i believe 75mm is last bore on the 5e blok right, cus my mech mentioned to me, if anything goes wrong, just standby a new 5e block:)

i will be running on ron97 and head is being pnp now, so just wanted to know what is max boost i can run safely...


thanks
