Chev Silverado 350 Cu. inch V8, fax

John,

Just a short note to let you know that I have had the Hiclone installed in my 1979 Chev Silverado (350 Cu. inch V8) for 665kms. Prior to the installation, my fuel consumption for the previous 2056 kms was 455.54 ltrs, giving a rate of 4.51 kms/litre. Since installation of the Hiclone my fuel consumption was 83.11 litres for 440 kms. Therefore a return of 5.29 kms/litre.

This represents an increase in distance traveled per litre of 17.29%!! A very good result indeed!! Additionally, cold weather starting, idling, and oil consumption have all shown much improved performance levels!

I am very happy with the Hiclone and would recommend it to any vehicle operator!! Feel free to use these comments in any fashion you wish! Thank you and Kind regards...

Jeep Cherokee 2004

As I drove onto the freeway I noticed an increase in performance as the jeep picked up speed much faster than before, as I was driving the car with the accelerator pushed to the floor I hadn't expected an improvement in fuel economy. Once I had filled up, I drove the Jeep normally getting at least 100km more from a tank of premium unleaded (shell optimax). I then fitted a K and N air filter and performance seemed to improve again. Needless to say I wont be asking for a refund as the combination of Hiclone and the K and N air filter gave me a power gain 19kw on the dyno.

Turbo Diesel Cherokee

Hi John

I received the Hiclone and am very impressed with the effect on the engine. No data on fuel consumption yet, but the smoothing of the engine and the extra torque all through the rev band is very noticeable. In fact I am interested in putting another one in the engine. I have a turbo-diesel Cherokee and the device is in the airline right at the inlet to the engine. I would like to put a second one also in the same airline but is there a minimum or maximum spacing between the two devices for best effect? Or is it better to put a second one in the line from the filter to the turbo or from the turbo to the intercooler? What about the effect of 3 of your devices? Looking forward to your reply...

Three Hiclones can be used, two between intercooler and engine if you can get 8" between them and one pre-turbo (minimum 8" from turbo) to bring the turbo on earlier.

Voyager 1999

I purchased a Hiclone for my V6 1999 Chrysler Voyager in late May early June. To my surprise it actually improved my fuel economy. Around town was 16.442 mpg and now is 17.719 mpg, an improvement of 7.7%. Highway was 24.94 mpg and now is 28.166 mpg, an improvement of 12.9%. I'm very please with the results and thought you would appreciate the feed back.
