I also had an 1HDT and put a
snorkel on it, I think it was a safari type that had the forward facing ram type head.
Whilst I didn't really notice any gain in power or fuel economy overall, there was a noticeable gain in power when it was a cool humid night, living on the South coast of New south wales and constant commutes to
Canberra, I got a very good "feel" on how it performed in undulating country and there was tangible difference between doing a day run or early morning run.
again, I have no scientific data to back this up,
I wanted a
snorkel mainly for river crossings and cleaner air.
I now have a 1HZ with the factory
snorkel that has a large pre-cleaner that seems to work
well.
A lot of primemovers have there air intakes extented to above windsreen height with the theory that the air is cooler and denser (not to mention cleaner on dusty roads) thus gaining more power, not so much during the day but when the sun goes down the road retains a lot of heat, getting air from 4 meters above will be cooler,
well, thats the theory anyway.
