reducing smoke for mot - bayley - 03-10-2012
got my car booked in for an mot tomoz...do i screw the boost compensator all the way in to reduse boost smoke as i have been informed they are tested on smoke not emmisions ?
RE: reducing smoke for mot - Ben - 03-10-2012
I'd turn down the max fuel screw. I did this and probably had about 60bhp! But I got 0.38 for my smoke test as opposed to the 2.77 I got the year before!

Lucas pump i take it?
RE: reducing smoke for mot - bayley - 03-10-2012
lol,think you are allowed up to 3.4 on the smoke test....do you reacon i would get away with a pass by just turning the boost screw back in ?

RE: reducing smoke for mot - Jenkosowls - 03-10-2012
id altered my pump that much that by turning it back down to standard it wouldnt rev at all and then the guy just held his thumb over the nozzle!
RE: reducing smoke for mot - Mattcheese31 - 03-10-2012
you need to turn your max fuel down if it's really high, ball ache on the Lucas i know . .
RE: reducing smoke for mot - bayley - 03-10-2012
haha,migth just turn the boost compensator down and see what happens..hoping it passes,need it for work on weekends but if it fails i will just use it with no mot and get it done for monday.{sorry officer i did'nt know the mot was up honest} lol

RE: reducing smoke for mot - Mattcheese31 - 03-10-2012
see if it passes if not turn it down and back for the free re-test . . . . .you could also adjust the throttle cable so it won't rev all the way . .

The 3 tests I've done have passed by just limiting the throttle travel, simples.

RE: reducing smoke for mot - strictly_perv - 03-10-2012
I was even told it "wen't really well" in that current stage :\
RE: reducing smoke for mot - bayley - 03-10-2012
thought matt was taking the piss,lol.how do you limit the throttle travel men ?
RE: reducing smoke for mot - strictly_perv - 03-10-2012
If you look at the pump and push the lever, it will come to a stop against a screw, just wind it in to a point where the smoke acceptable. Done.
RE: reducing smoke for mot - bayley - 03-10-2012
wind in the screw that stops the lever opening to full throttle yeh ?

That's it. Depending on tune it will probably need about half the travel limited.
RE: reducing smoke for mot - bayley - 03-10-2012

RE: reducing smoke for mot - c.gerrard - 03-10-2012
Why don't you go other way and create so much smoke they can't read the results?
