stupid question time

<< < (4/4)

Porny:
More fuel = more power = higher EGT (exhaust gas temp)....

The problem with a diesel, unlike a petrol engine, is the more fuel you put in, the higher the EGT becomes and very high EGT is not good.....

However a problem will only occur if you keep your foot flat to the floor for a long time with the engine under load.... i.e pulling your caravan up a long hill on full boost.

The tweaks you have done are basically the same as my 90" when I had a 200Tdi fitted....

I regularly towed a loaded trailer without a problem... and my 90" when solo was often driven 'enthusiastically'!!!  :twisted:

One point is that you haven’t actually adjusted overall fueling, so in theory…. EGT at full load should only be slightly higher (if not the same)

The tweaks you have done, simply put more fuel in at lower speeds/loads which in turn will make the turbo spin up faster (thus start boosting quicker) reducing lag and improving low speed pick up.


IMHO you should not have a problem, just remember not keep your foot flat to the floor for too long if you are worried.

Topple:
Thanks Ian,

I'll let you know how my trip to salisbury goes on friday.

Xtremeteam:
when i tweaked mine on sat i turned the diaphram from 11.55 to 3.15 & i rekon its runnin about 17 psi of boost (1n a wee bit bar) n it now goes like stink,runs out of gears even on 750's,

i was also concerened about the EGT thing as mines smokes most of the time when the coals being shoveled
