Les Henson Posted March 2, 2009 Share Posted March 2, 2009 I volunteered to make a snorkel top for V8 Freaks 4.6 V8 bunny killer . Not really a technical thread as I forgot to take pictures/didn't think many people would do it. This is my 6th attempt - drilling a neat pattern of holes or slots is really difficult, plus things such as minimal restriction of air flow - both through the holes and air flow through the snorkel body and connecting pipework. I used a 2kg Co2 fire extinguisher to make the body of the snorkel, then 57 x 12mm holes - done with a hand drill There's also a gutter to prevent water from running down the cylinder of the snorkel top and into the intake. Not finished yet (obviously), the gutter has to be seam welded and the pipe stub to be connected at an angle to the bottom of it, then clean the inside and blank the other end off. More pics will follow as I work/finish it. Les. Quote Link to comment Share on other sites More sharing options...
BogMonster Posted March 2, 2009 Share Posted March 2, 2009 I used a 2kg Co2 fire extinguisher to make the body of the snorkel, Did it make a loud bang when you drilled the first hole in it? Drilling holes neatly ... bluddy difficult! Quote Link to comment Share on other sites More sharing options...
TheRecklessEngineer Posted March 2, 2009 Share Posted March 2, 2009 Looking good Les, but the top row of holes look a little wobbly... Quote Link to comment Share on other sites More sharing options...
Les Henson Posted March 2, 2009 Author Share Posted March 2, 2009 Did it make a loud bang when you drilled the first hole in it? No, but I got a bit damned close Didn't get much more done today. Seam welded the gutter, then tarted it up with filler, and then wore my finger out smoothing it into profile. Les Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted March 2, 2009 Share Posted March 2, 2009 ^^^ Mmmmm Nice I did similar with mine, and yep as others have said drilling a line(s) of holes is a nigtmere. On mine to help with the holes I used some graph paper, and stuck in on with seletape Then went all the way around where is had been marked for holes and hole punched the F lot removed the paper and there were all the holes Clamped (not easy ... then drilled all the holes hole punched with a small hole, then a bigger one, Its one of those jobs that can be messed up in a careless moment, so just take your time Nice tho Les, if he argues on the price go to Plan B - grate his head with it Nige Quote Link to comment Share on other sites More sharing options...

simonr Posted March 3, 2009 Share Posted March 3, 2009 Doh!Why do we have lasers and cnc drives................................... Beat me to it! I was going to say that Dave can laser cut tube - so putting in perfect lines of holes is not a problem - you could even cut out pictures - how classy would that be?!

Les Henson Posted March 15, 2009 Author Share Posted March 15, 2009 Nearly finished Just the 90-deg bend to weld to it. A change of plan meant the pipe was going in the end - rather than at an angle underneath as I originally intended. Also - thicker steel to cap the ends off to prevent vibration cracking, so 2mm thick at those points. And three drainage holes at the bottom as the top could hold about 1/2 pint of water. Les.

Megansfolly Posted March 17, 2009 Share Posted March 17, 2009 looks good les here is one of the diffusers i design for the silencers at work. This one been made in our new factory in india all holes are hand drilled no jig just a paper drillin template stuck to the Nozzle then drilled Quote Link to comment Share on other sites More sharing options...
Les Henson Posted March 18, 2009 Author Share Posted March 18, 2009 Just about done now 90-deg stainless bend (bit of care here to make sure the vertical pipe-to-snorkel top will still be 90-deg) I couldn't do a decent weld from mild to stainless, so opted for a massive weld that then needed tarting up with the angle grinder. Some more filler to make it look half decent/cover up the rubbish weld Just the vertical pipe to attach now, so that the external snorkel is all one piece and will be removeable as one piece from the wing top. Oh - and a paint job Les. Quote Link to comment Share on other sites More sharing options...
Les Henson Posted April 6, 2009 Author Share Posted April 6, 2009 Final installment - doing the rest of the work on the vehicle. The materials needed to finish it are 2 x 1m x 75mm I/D bore stainless steel tubing, 3 x 90-deg bends, 1 x 45-deg bend, some 2.5mm mild steel plate, and 75mm I/D silicone tubing (about 4-inches of it) The idea is to make the section above the wing in a single removeable piece, then another piece from under the wing to the engine bay, and then the connection to the air filter housing, so a 3-piece system, with minimal risk of any leaks. Not really much measuring - just eyeing it up, and crossing fingers FYI - the snorkel is for a 4.6V8 110 CSW with as near zero restriction of airflow throughout the system (some popular makes of snorkel have a choke point in the system). Wing top plates first - 2.5mm plates with m8 studs welded to the top one to clamp the plates top and bottom of the wing top. How top and bottom section are joined - The first 90-deg bend - 'eyed' so that it will end-up just outside of the screen hinge, then 40cm and another 90-deg bend to get it to point upwards. 45-deg bend trimmed to follow the angle of the screen/vent panel, then angle cut the next section of tube to lean inwards and follow the edge of the screen. There was previously a Safari snorkel, so the same mounting point is used to prevent any unsightly holes in the A-pillar. Get some old geezer to position the snorkel top for the final alighnment. Final weld- Final mounting point on the end of the top to keep everything still. The finished item - ready to go and get tarted up. Under the wing next. Pipe is 77mm O/D, and the gap is 82mm A couple of DIY bends in order to miss the brake master, some silicone tubing, 40cm of tubing with another DIY bend in it to aim at the air box, then a final piece of tubing to connect it all up. Just one more picture to finish this thread, and that's when the snorkel is painted and fitted for the final time at the end of the week hopefully. I'm very pleased with how it turned out, considering most of it is done by eye. FYI - from the drivers seat the snorkel can't be seen at all, except where it passes along the wing top, so zero effect on visibility. Les.

Hybrid_From_Hell Posted April 6, 2009 Share Posted April 6, 2009 I like that a lot Its spookily similar to mine too Much better design IMHO than side wing entry models that can get whacked and then open up damaged to the elements, neat tight and kin strong too Dive Dive Dive ..................

western Posted April 6, 2009 Share Posted April 6, 2009 Neil, will want a matching pair next or a periscope on the otherside for really deep wading. Quote Link to comment Share on other sites More sharing options...
V8 Freak Posted April 6, 2009 Share Posted April 6, 2009 It's "just in case I venture near a puddle..." I have to say Les has done a fantastic job. As he says it's pretty much invisible from inside the truck. It's gone away to be painted red, white and sky blue pink so it doesn't stand out at all... Will have it back this weekend hopefully. If Mrs Freak lets me near the truck this weekend it'll be fitted. Some RTV (sensor safe) sealant between the plates will be the final seal in the snorkel. New filter to go in the airbox and that will be sealed up too.... If I can find someone with large hands to cover the top. I'll test the air seals... Fingers crossed it will be totally airtight !! When it's back, all nicely decorated (Maybe with some sprinkling of glitter too to keep Nige happy), I'll pop some pictures up in this thread. Many thanks for all the great work Les....

V8 Freak Posted April 10, 2009 Share Posted April 10, 2009 Well it got sprayed.. They did a wonderful job too. Here are a few pics all connected up like. Taken it for a run and no noises etc. so it's perfik innit.. .Wikkid... It didn't break free and leave the truck on a "private" road at some slightly fast speeds either so I believe it will survive normal, legal, speeds no problems Neil Quote Link to comment Share on other sites More sharing options...
