IVAC amplifier

pingman, dun worri so much lah.

Today I was with kiddy_M when he got both the coil booster & I-Vac installed into his N52 630.

Took 40mins & after that, we went for a short drive.....

U can see his face with joy everytime he taps alittle on the throttle!!

4-ground plugs means the Bosch Super 4 plugs. They have 4 legs so that the sparks has more possible contact points to fire at. Normal plugs and your iridium high peformance plugs are usually single -ground (1 leg).

The Bosch 4-ground plugs are cheap and good. A copy and paste from Bosch's webby:



Your engine's new performance-enhancer: the high-power spark plug for retrofitting.

Another innovative idea from Bosch. The Bosch Super 4 operates on the state-of-the-art air-cushion-spark principle and is the first spark plug to feature four thin ground electrodes with one pointed, silver-plated center electrode.

This combination is unique in the world and has decisive benefits. The ignition spark always chooses the best path for reliable ignition according to the engine load.

Technical superiority - now available for your car.

The Bosch Super 4 does more than a conventional spark plug. In all situations, throughout its service life.
The advantages:

Noticeable improvement in acceleration

Significantly improved engine smoothness

Superior engine versatility

Electrode gap adjusted ex factory





A normal single ground plug:

Pingman... this must get!! Make ur 730i into a rocket!!! Can smoked tire, smoked cars, smoked girls!!! Best!!
Proven liao... Wilson (and his hyper sensitive Butt) and me (kiddy butt) tried it!

It really depends on your IVAC voltage setting and the way you drive your car.

If you set it at a conservative voltage and drive like all good Singaporeans should, the lifespan of your plugs should not be very different from a stock setup. Which brings us back to the whole point of this mod. You want gains, you need to set your voltage a lot higher than 13.6v, which naturally will push the envelope of certain electrical components like ignition coils and spark plugs. So in that sense, you will be wearing out your plugs sooner than normal with this mod.

As to how much the lifespan of the plugs will be shortened, I really have no idea. Many factors contribute to this. In any case, you will know it when your car feels weak and starts misfiring during high end. When that happens, check out your plugs and change them out.

Hmmmm..interesting. Think i will have to get this one mod done before TD !!

FR due soon next week !

a) the battery is used to start up your car.all power after tat is from your alternator.so how can an increased battery output increase performance when its not even in use?

b) ignition cables and spark plugs are rated at a certain voltage.if you pump more voltage then its rated for thru it, it will still produce the amount of volts it was manufactured to (assuming it doesnt blow).spark plug cables meter out your voltage in pulses, so no matter how much voltage you try to pump thru, it will still produce only the amount of voltage it was made to produce.

c) if you pump more voltage then an electrical appliance was designed for, wun the appliance blow?

d) your spark plugs produce sparks for combustion.no matter how much volts you pump thru it, it will still only produce the same intentsity of sparks.even if the intentsity of the sparks can be increased, without an increase in air/fuel, the same amount of combustion takes place!

Went down to BVO and installed IVAC plus OWS engine and original BMW transmission oil changes 3 days back. The Volkers were swapped for the original factory NGK 4 ground plugs were re-installed. Did not go for the coil booster.
I can say that there is definite improvement in engine reveability ( smoother and quieter ) and there is perceived overall increase in pulling power esp from 2500 rpm onwards. The car feels 'lighter'.

Regret is that unable to separate how much of the change is attributable to the IVAC and how much to the oils ( engine & transmission ).

How to 'tune' the IVAC voltage? Can I do it DIY?? Anyone please enlighten.

if you have Tools for Monitor voltage & Amper. and if you know about Ignition system well.
may be you can tune your self. but that is your own risk.

differed years model use fiffered volt age. some of car can go 19Voltage some car only 16volt age.
BVO they set volt age for you to do not make any probrem with your car.
they are Professional for BMW . you need take Advice from them.

have a good driveing.

[hitmee]

is it advisable to fix the coil booster first. drive for a while then fix the IVAC?
seemd like coil booster give better torque, IVAC makes it smoother?

how long does it takes to fix on the coil booster huh? do i need to make appt with BVO or i can just drive in?
