WITHOUT causing a misfire??


ie... the car feels a bit flat like the timing is pulling back?

Yes.

The weaker spark only ignites a small portion of the total spark availablity
surface area so it takes extra time for the already burning mixture to
ignite the rest. In effect, this is like retarding the ignition very slightly.

 

as above but in simpler terms............."yes"............. every plug has to be sweet

 

TBH i wouldnt think you could feel it

 

GARETH T,

Turn the dwell time down on your T6 and take it for a spin under load

 

ill have a go once it back together simon im sure your right though

i thought it would missfire rather than a loose noticable power

 

quite hard to notice a missfire when youre giving it beans tho?

 

Totally Correct. Result on analysis machines is High HC PPm.

Incidentally, this is how swopping to wasted spark can improve your power output for the same boost.

 

stu like i said on the last thread,,, i understand the result but aint got a clue what hc ppm means,,,,, im guessing its hydrocarbons per mixture of what ever amount just like the mot machine reads

but aslong as i know the end result ill get by ok

 

parts per million i think

 

Hydrocarbon parts per million

 

see i learnt something

 

no but a a large crack in your block and water all over my drive will certainly not be doing you any favours

 

Ha bloody ha

 

you can even break them on idle

did you buy them studs ?

 

No matey... not done anything yet... gonna sleep on it

 

HC = HYDROCARBONS ie UNBURNT FUEL
PPM = PARTS PER MILLION, of UNBURNT FUELL
NO engine in the world ever burns all it 's fuel in the cylinder.
