whats best pressure for 1.6 stock mivec...?? opinion pls..

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.

 

[GT_AUTO]

over at my plc,mivec n 93 pressure usually set higher then 40psi but
below 46psi.

 

[wira_tak_laju]

GT auto - usaid higher thn 40 psi ,below 46psi..is this idle or WOT??..whts ur recomended set up then?? idle and WOT..need opinion as i m playing around with this unit to see which is best power..he he tarak bujet dyno le

 

[GT_AUTO]

the press that i'm talking about is at idle.maybe it's the same as fstrader if
wot.

 

[kelv!n]

got a question here... wats the diff between the big and small sard fuel regulator? and wat shud be the ideal pressure for 4g18?

 

[GT_AUTO]

same as the mention above.sard big can withstand higher press.ideal
for force induction engine.

Sifoo,

Been hearing alot of this f/reg. Just 1 'q'... do carb engine uses 1 too?? or is it juz for fuel injection?

[kelv!n]

so which means since that my ride is NA is ideal that i get the small and not the bigger one rite?

nope, FPR only for fuel injection cars

only for fuel injected car.

 

[4ndr3wt1n]

Thx 4 d resp sifoos... so carb can use fpr n not fuel regulator? wats fpr? fuel pressure regulator? :hmmmm: Is there a diff?. Seekin sifoo guidance


Rgds,

FPR=fuel press. regulator.

 

[SkYwAlKeR]

sifoo gt-auto-san, carbie cannot use FPR meh??... i saw before FPR in carbie wo....

 

[ahgy]

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...

really ar???then where the pressure come from leh???carb don't use fuel pump
right.install it for look is it???if that engine don't have fuel pump,how can
he block the fuel from returning to the fuel tank.

got ler... carbie cars using mechanical fuel pump... if no fuel pump, how the fuel can travel from fuel tank to engine??...

 

[fstr]

aiyahh i tried putting fpr edi on my carb engine last time d laa...not enuf pressure to pump fuel..

 

[GT_AUTO]

yeah lor,no press how to install?if u can install also ar,how high the press?
if u set it to high,will it broke ur pump?

 

[GT_AUTO]

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.
