thread bump.
has anyone had experience with WMI on diesels? ive taken my AEM kit out of my skyline and fitted to my '92 Rodeo with 2.8TD. the engine is stock with only a catch can and bleed valve set to 14psi modified. ive yet to experiment much but have tested quite a bit.
currently have the medium nozzle fitted which i believe is 500cc/min. with straight water i feel no power difference and no change at all in EGT. even switching it on up a hill with steady temp i see less than a 5C drop.
with a 50/50 mix its a complete animal. its like driving a new model diesel with an estimated 30-40% more torque with boost in 1000-1200rpm earlier. peak EGT before and with water is 515C. with 50/50 peak temp has been 565C although boost is higher so its not really comparing apples. hills i used to climb at 70km/h in 4th, i can now stay in 5th at 100km/h. im going to drop back to the smallest nozzle which i believe is 250cc/min and compare again.
When i have time im going to fit another pyro in the intake somewhere to see temps as im not intercooled so i expect decent drops with meth injecting. anyone have clues why EGT's dont decrease when activated compared to not injecting?? i was expecting 50C at a guess but got nothing. i never monitored EGT in my skyline so nothing else to compare to
cheers
so i flushed the tank out today and started running the ute on water with no methanol,
its an 'ol slug again definetely going back to methanol. max exhaust temp 515C on diesel and water. 565C on diesel, water and methanol. safe as houses
