DIY - Install Vacuum Meter

[jaywat]

Hahahaha correct correct :lol:

Hey guys, im getting a vacuum meter from ftzone too and i need some guide connecting the hose. Im driving wira 1.3 carburetor so need to know where to tap the vacuum hose.

I know got one hose connected to the bottom part of the air filter and the front part of the air filter inlet pipe. I dont see why the air filter need vacuum. Is it because to suck air in kah? I remember last time when i installed open pod air filter(powerflow), that one vacuum hose was unattached and i had to blocked it off if not my engine would have a rough idle(rpm goes up and down).

If i should tap from there, should i just unplug the vacuum hose to the air filter or should i leave the hose attached to the air filter and add a t joint?

Thanks!! :)

Oh, so tap anywhere also can lah. Wont affect reading much right?

Whats the usual vacuum for 1.3 without air con and with air con. Any ideas?

BTW, whats a microcompressor and what does it do?

Thanks! :)

jaywat,

mind to show me which opening on the fire wall did you use? I am about to install one too.. Got everything ready except the meter hahaha!!!

hmm.. about the grounding cable, it's actually 6ga skin and 8ga core. As examined by some of our gang that 'sacrifice' one cable due to its length. By the way, the 'think skin' so looks nice..

khguan is selling off his, any taker? haha!! I am selling off mine too (cheapskate DIY).. any taker?

Anyway, thank you in advance for the photos on how you pass the tube over the firewall.

i personally think that the DIY bracket is much nicer than the RM10 one https://www.zerotohundred.com/forums/style_emoticons/default/laugh.gif alt='laugh.gif' /> ... that bracket only hold the meter standing horizontally...not vertically , like mine https://www.zerotohundred.com/forums/style_emoticons/default/cool.gif alt='cool.gif' />

Won't affect much one...if u seal every connection point properly.. B) ...best way to know that u have install everything properly is reading the vacuum meter... ;)

standard reading is 20...mine is 18, because of extra suction opening at microcompressor part..

btw, microcompressor is to let more air into intake manifold so that engine will run lean.. better a/f ratio...more power because fuel burn more complete bla bla bla ...e.g: 2 portion of fuel mixed with 1.5 portion of air = 1.5 output of power + waste energy, while 2 portion of fuel mixed with 2 portion of air = 2 output of power + 0 waste energy...so same amount of fuel can produce more power and mileage...muaahahahaha :lol:

JMSO...flaming are welcome :ph34r: :ph34r:

Hey guys, i got my vacuum meter from ftzone today and installed it this afternoon.

Anyway, i just need to clarify on one the reading. I didnt tap my vacuum from the air filter there but i tapped from the er...a small black hose from the engine block there. It leads to a t-joint where from there it goes to the back of the carburetor and another to a small gadget(dunno what is it for) mounted at the firewall.

I saw my friend tapped his after that t-joint(for his car) but i tapped mine before the t-joint. Ok, the readings i got problem.

If i on engine, my reading would be around 20-22 without air con and 15-17 with air con on. The readings are quite the same for my friend but the problem is that, if he rev his engine, his readings can get to 0 easily, but i cant. The most i think i can get is 5psi. SO which should be the right one?

BTW, he's using a chepear Type-R brand vacuum meter while im using auto gauge smoked series, not so 'keng' also but better than his.

Just wondering any problems with my engine or his or maybe installed salah...anything....please let me know. Thanks! :unsure:

Your meter reading also like mine or my friend's? So you mean no matter what, your readings seldom hit 0psi is it?

hi friggles.. u the sarawakian? hmmm :lol: u can only get 0psi reading easily when your engine is underload.. meaning.. at certain gear and throttle ler... on a stand still cannot get 0psi ler... btw... the best vacuum source would be from the intake manifold...

Hi! I got the meter, thanks! I recommend this seller! :)

The problem is that i dont really know where is the intake manifold. Ok, so now i know that it's not that often i get a 0psi reading.

I drove my car today for the first time. And i noticed that if i accelerate from standstill, my reading would be like around 6psi, and then slowly it'll drop back to er...10psi maybe, around that. Question: Does the vacuum meter slowly goes back to a higher level even when u keep the same level of pressure on the pedal?? Like when u're crusing, or when u're accelerating? Or does the meter follows exactly the pressure on the pedal, meaning no matter what, how hard u step on the accelerator, the meter reading will hold.

Thanks!
