i hear some say svt piston is more hi compresure then bt??if yas i wish to put it to my bt..

iziz true!!hear i some say some1 use the stv piston on his bt,it go very fast....
dun always hear ppl say, search the web and see yourself, u want more compression and more power go for Toda piston 11.6:1 compression (286.49g), ori backtop 11:1 compression (293.57g).
my fren used svtop wit blaktop head..coz the comprasion slighter higer cmpare to svtop head...
I wrote that article linked above and I can tell you that running silvertop pistons with a blacktop head lowers the compression ratio not raises it

hi sam,
didn't realize that you've joined ZTH...
A BIG WELCOME....
can I know what's your current setup?
I'm still looking at putting in COP as per discussed in Club4AG...
however due to the current situation, probably upgrading to Haltech S500 at the same time...
scare to run DLI on stock ecu...
btw, i'm having emanage blue...
to thread owner...
this is one of the thing I've think of but decide otherwise after further search in Club4AG and 9000rpm forums...
yes, it does lowers compression...
however all things will depends on your overall setup actually, which is probably why you mentioned that your friend setup is fast...
as normally people will put in metal gasket and probably skim a bit the head...
so it's a compromise somewhat...:hmmmm:
sorry sifoo...need to clarify here...using svtop blok wit blaktop head and piston :)
well it's not the price so much as the lack of need. If the aftermarket pistons are not significantly lighter then why not use standard? As I said previously using a 0.8mm gasket can raise the compression if wanted and as a bonus reduces the quench area height making the chamber more theoreticly efficient in combustion. I also think that the higher dome shape also divides the flame front more which amplifies the flawed shape of a 5V chamber design.

bro and all bros,
using this setup, the compression ratio will be less than 11:1 or less than 10:5?
can shed some light?
