reducing smoke for mot

[bayley]

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 ?

[Ben]

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?

[bayley]

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 ?

yes mate,does'nt smoke that much since i removed the cat and middle box for a 2.5" stainless pipe.

[Jenkosowls]

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!

[Mattcheese31]

you need to turn your max fuel down if it's really high, ball ache on the Lucas i know . .

[bayley]

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

well its all the way in tight then back half a turn...23psi.i put it in 3rd gear and push it backwards whilst holding a mirror in the other hand,takes about 30 secs to line up.

[Mattcheese31]

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 . .

[bayley]

lmao..good job i'me not nieve mate.

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

Exactly this! Mine got 0.00 emissions last year! Lol :-0

[strictly_perv]

I was even told it "wen't really well" in that current stage :\

[bayley]

thought matt was taking the piss,lol.how do you limit the throttle travel men ?

[strictly_perv]

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.

[bayley]

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.

[bayley]

sound mate ill give it a bash tomoz.

[c.gerrard]

Why don't you go other way and create so much smoke they can't read the results?

[Mattcheese31]
