whats best pressure for 1.6 stock mivec...?? opinion pls..
stock for mivec shud be 35-42 psi.

4g91 stock shud be 28-32 psi.

4g93 stock shud be 34 to 38.

that is just for guidance and it shud compensate with wat u have done to ur internals and ur add-ons.

arospeed quite ok..i am using arospeed at 40psi on 1.6 n/a ... there are diffs with n without this gadget... after installing this afr , i accelerate less than 50% when power require.. b4 i install this , i haf to accelerate atleast 70% ...this this doesnt increase hp la..but makes ur car feel smooth when accelerating.. n/a car dun haf to use dual diaphram afr... unless ur car a real monster... but for turbo car like gsr or bolt on , single diaphram aft also can...

1 more thing to add,fpr works differently if u install it on carb.inj is diff.
inj got 4 injector that spray the fuel directly in to the combustion chamber
while carb split the fuel to 4 diff runner that will then enter the combustion
chamber.by installing the fpr,ur can alter the spray pattern of the injecten
in to the combustion chamber.by increasing the press,the fuel will be finer
n much more easier for the spark to burn.that's why by installing fpr,u can
feel ur acceleration is improve.in some cases,fpr can increase hp.it's also
work as a fuel adder.
