Snorkles

Here's a very good article on ram-air tests done on motorbikes.
Sport Rider-ram air induction test for sport bike motorcycles

Good read. So cant I ask a stupid question then?

If on a petrol Rangie, if you saying that the electrics will cause the engine to stop because of deep water, then how can one prevent this? Or if it cant be prevented, then is it worth spending the $$ (although I wont, ill make one) on a snorkle assuming you do want deep water crossing (aside from other benefits)?

Hmmm, I should ask justinc how much it costs to install a diesel isuzu in my Rangie :p

Do it, you will never look back.
When the engine wears out the rest of the vehicle, bolt it into another one and keep goign.:)

I don't even know what a carby is!?:wasntme:

It's like an abacus, but bolts to a petrol engine.

I was hoping when you mentioned PVC pipe that you had made the whole thing from PVC including the external part.
I have considered making a snorkel for my 300Tdi Defender from PVC and wondered if anyone could think of any reason why it would be a bad idea.
My thinking was that there are so many sizes and so many angle fittings available it should be possible to get just the shape I need.
I also thought that if I made a new plate for where the air intake is in the mudguard, I could return the vehicle to standard just by putting the original plate back.
I figure that if I bump into a tree or something, it doesn't matter if it breaks because I still have the original air filter doing what it always did.
I thought it would be easy to seal and pretty cheap to make.
My main concern was the heat in the engine bay, but your experience suggests that is not a problem.

Any thoughts on the subject?

Alan, if you were going to have a long length of PVC under the bonnet I would use 90mm drain-pipe (not stormwater down pipe) as it is built to handle hot water with no problems and if it were to pass near a hot spot I would sheild it, if you wish I'll drop down and have a look at what's needed.
Took a run down Rebecca Fire Trail on the way to Bendethra on Tuesday, spent a lovely night at Bendethra, only 1/2 a dozen campers there, water was like ice, but was good once you were in for a while, Regards Frank.

How do you find the extractors?
More heat inside the cab?
Noise?

Cheers

Ron, thanks, the extractors dont seem to make it too hot under the bonnet, they are fairly low down, I havent noticed any extra heat in the cab. I have a 2 1/2" exhaust system with a straight thru muffler and a resonater and it's a little bit too noisy, but it sure sounds sweet, it probably would have been quieter with twin exhausts but hard to get thru the drivers side as I have a 135 litre fuel tank and would have cost twice as much, Regards Frank.

Water on the distributor, leads and plugs will stop it even before its submerged if its anything like mine. I believe that EDIS (electronic distributorless ignition system) will solve alot of this. Its my next project, but not for underwater reasons...

However, i don't believe the comment your replying to is 100% correct (:o), as water can still splash/spray into the air intake before you're up to your knees in water. IMHO a snorkel will solve half the problem of swimming 4x4s, and more importantly, solve the more serious one (water in the air intake can be very bad news, water on the dizzy means SFA except the car stalls).

As with all my technical posts, please correct me if i'm wrong :(

Are you're $$$ refering to the snorkel conversion (which his $$$ were), or the deisel conversion? :p
