Hello to all of you who are interested.
Phase 1 testing was completed. Stopwatched a fairly steep
hill from one fixed point to another prior to installation of 2 Hiclones. Took exactly 31 seconds (a distance of about 700m). Did another section of a
hill, took 11 seconds. Repeated these two tests three times each and got pretty close results, within .04 of a second, which proves I was pretty spot on with my start and stop points.
Phase 2 - Got the Hiclones fitted. I am not a techincal person, but what the mechanic chaged me $40 was an absolute ripoff - if after reading this anyone wants to get them installed DIY - you can, with your eyes shut!
Phase 3 - Anyway, drove round for about 15 minutes (to allow the computer to adjust to the difference in so-called airflow), and repeated the tests. NOT A SCRAP OF DIFFERENCE, SURPRISE SURPRISE. Could not hear a difference in the note of the engine, as some have reported. I think the turbo started really pulling me away at about 200rpm earlier, but this could be in my mind. There is no real laymans way to
test this, I know.
There was one unanticipated benefit I discovered. I can not tell for sure if it is because of the Hiclones or merely coincidence, but ever since I had a Safari
Snorkel installed (about 4 weeks ago) There was a distinct and very annoying resonation (I think that's how you spell it) coming from the general victinity - I could not work out if it was from the A-Pillar, the
snorkel itself, where it goes though the front panel or what, but since the Hiclones went in it has completely disappeared. The vibrations only occurred at certain revs - about 2400-2600 and then died, but were even worst in the rev range when decellerating. I have read a little about this sort of problem and it seems relatively common.
Will take out the hiclones at some stage and see if the vibrations come back
Just thought you might be interested. I will be trialling the car on the same hills again in a week or so, so stay tuned (yeh yeh yeh I know conditions will be different but though it would be interesting anyway)
Phase 4 - stay tuned for fuel economy figures and more exciting Hiclone talk from D-Jack!
