Myself as well mate - which leads me to this question.....

I bought 1500mm of 3" exhaust pipe and fabricated my own...... Rather than getting an exhaust place to bend the pipe, I 'lobsterbacked' it; cut sections around the curves and welded it. Came up a treat. Cost around $150 total- including the pre-cleaner on top.

Lobsterbacked ??? WTF ?

In the next week I am going to be sourcing the bits I need for the job - can you just exspand on what I need to do??

I have pictured it was a case of cutting the pipe in the lengths - and just use the rubber bends to put it all together & just cut the horn off & flange for the rubbing hosing??

Here are some pics of my set up at the moment. Pretty much the same set-up as Ron's except for the curved steel pipe out of the air filter box (.

Is that Agg pipe??
Looks just like what I need to do My Gas system might be in the way a little - but nothing I can't sort out.

Is there anything else that has been done to seal up the airbox\filter area from water or a drain place for water coming down the snorkel??

Here is a few pics of the snorkel set up on a RR I used to own. There is a place in Kilsyth that make roll bars and can bend you up an ally snorkel (like what I had on the RR in the pics). I have bought mandrel bends from them before and there quite cheap. Cheaper than a LRA one if your on a budget. I wont post pics of the 94 RR Classic I have now as it has a different air box (plastic one).

Cheers

I am guessing thats a carbied engine?

No its EFI 4.6 with a custom twin throttle body plenum. This motor had a fair bit of work done to it, went really well. The engine was built by Bruce Davis in NSW.

I will post a pic on monday but do you think it would work if i was to put a pipe over my K&N filter ( which is cylindrical) then run it directly out to the snorkel ?

This would mean that the air is only coming in one end of the filter ?

Or is it better to make up a larger pipe so the air flows right around the filter.

What would be optimum for the engine ? Im guessing as much air as possible.

Cheers Sean

'Lobsterback' is a method of forming a bend in steel pipe by cutting and welding rather than mandrel bending. The pipe is cut on an angle, then rotated in the saw 180 degrees and cut on the same angle the opposite way, this gives you a wedge-shaped piece from between your 2 lengths of pipe. The wedge is welded back into the pipe the opposite way from how it came out, resulting in a bent pipe that resembles a lobster's tail. Can be done in as many steps (pieces) as you like. A bit of maths with the cut angles will get you a finished product with the angle you want, and by rotating the wedge you can fudge the angle a bit if necessary. Looks very neat if your welds are good (or you are good with a grinder).
I know a picture paints a thousand words, but I'm still waiting for my new camera to arrive in the mail, so hope this description makes sense.
