this is all a matter of opinion really, read what people say and make your own mind up. For me though:
pros:
- ptfe lubricates the charger much better than the scum that comes out of the oil breather (use a catch tank for a while and look at what collects in there)
- the charger is always taking in cold air from atmosphere not heated up air recirculating through the boost return (colder air = denser air = more power)
- the noises, they sound cool!
cons:
- you have to remember to lubricate the charger every so often or you'll kill it, also not put too much ptfe into it
- the noise??? some people don't like it...
-The distance of spraying PTFE (every how many miles)?
I give it about five short sprays every 1000 miles. It's not an exact science but that seems to be roughly the right amount.
-When i take of the boost return hose, i have to conect the oil vapour tube with a small filter or i leave it like that?
run a pipe from the breather pod (remove the plastic one-way valve) to a catch tank. If you just leave the pipe open or even with a filter on it you'll get oil vapours and mist all over your engine bay.
-I have to close the left chargers port (the cap is going to be a custom made)
yes, or run twin inlets. A few years ago the done thing was using twin inlets where you have an airfilter on each charger inlet. These days everyone just puts blanking plates over the 2nd inlet. I got rid of my 2nd inlet with a blanking plate to gain a bit more under bonnet space.
-Any power gain?
technically there should be a slight increase, yes. Not massive though!
-Will the fuel consumption increased?
not noticeably so if at all.
-In a stock G do i hear the whoshhh? (lol)
yes
Thank for your time, Alex!
no problem
Bear in mind, these are mainly my opinions, albeit gained with years of messing about with g40s and from advise from people in the know. I also know there are other people who think this modification is the spawn of the devil and will cause kittens to die.
