i sprayed some of this into the inlets as advised when running and i noticed that it changed the tone of the engine/charger for a few seconds as if the revs had dropped.
is this normal or could i have a problem somewhere
Some spray going right through the system into the combustion chambers; normal.
cool
How long do you guys spray it in? and do you cover the inlet with something else to seal it to the can when you do it?
yeah I used to give it some revs while doing it so the engine doesn't struggle. I never covered the inlet up or anything, just give it a bit of revs and spray in. Probably 3 or 4 short sprays for a second or two each. Don't go spraying tons of the stuff.
How often should you spray in to you charger?
PSD used to say every 1000 miles
what if its a weekend G thats made to get thrashed and driven hard?
I've sprayed some ptfe (6 short bursts) i loosed the belts and i rolled with my hand the charger and it was turning slightly hard (i have done the same test before spraying the ptfe when i had the boost return pipes). Has anybody rebuilt a charger that was using ptfe - are they lubricating ok?
