snorkel air ram effect

Do you mean the donaldson pre cleaner ? I have the air ram scoop and a pre filter for my patrol.The air ram is good on the road above say 60kph. The pre cleaner is good off road in dusty conditions and below 60kph. any faster and the dirt just comes through with the air.I find the pre cleaner restricts the air flow on road and uses more fuel to keep the car at the same speed.

Goodsy I think you can expect a reduction in both power and fuel economy but neither will be a huge difference.

Hi Goodsy, have a pre cleaner on my diesal patrol and have not noticed any difference in power or fuel, but have noticed i dont have to clean the first filter as much as the ram scoop. I run my pre cleaner all the time, and the only thing i have noticed is in heavy rain the bowl fills with water and that is with speeds above 60- 80 ks so may be the above comments arnt quite correct. Have done a lot of dirt and dusty driving and swear by them. Col

Hay Colin ,whats RAIN ?

I used my pre-cleaner to hide a spare key. By the time I got to Coober-Pedy the thing had ground itself to a point while spinning around and rubbing against the sand and bull-dust! Cheers Royce
