It is cheaper to repair an MS part in rural areas with some quick welding (assuming you sandwich your duct against a tree or rock). Repairing FRP is a tad more difficult. You can use duct-tape for sure but you know what I mean. The difference in weight isn't that much for a part like this that isn't load-bearing.

I don't know if that is acceptable reason. I have noticed major manufacturers produce their snorkel with Plastic/FRP kind of stuffs for duct. I leave Force Gurkha the only production with SS duct.

What could be the possible reasons for manufacturers choosing PVC/FRP based duct?

Because in bulk production, it's always cheaper. PVC costs nothing. Mould it and make it mass. Steel pipes need to be bent and takes more production time and money.

But, for a one off job, you're better off with steel.

Possible CMVR regulations???

Agreed, the plastic has another advantage of not rusting. Ever. But one can't get that great finish et al with a single homemade unit IMO.

Doc, Both Steel as well as PVC require similar equipment for bending and proper grades PVC costs money! not nothing. Ofcourse all this is if we are talking mass production.

A single piece is easier to make in steel or aluminium.

Are you sure? You bend PVC (plastics:- Thermosetting / Thermoplasts?) pipes with equipments similar to steel?

Spike

PS- Why do you use extrusion dies and moulds then?

Spikey!!!!!

Its obvious that steel and PVC {thermosetting as well as Thermoplastics} have a different scope / method of manufacture

What I meant was the method of costing calculated when it comes to Mass production.

BTW, why is M&M not resorting to FRP mudgaurds / panels - non load bearing member stuctures if it is cheaper than STEEL? Think my friend and you will get the answer!

Also can you name a proper 4x4 that has the above - clue - The vehicle weight unladen is only around 1400 odd kgs and develops over 140 BHP, has 4x4 and low ratio.

Sad it has not caught the fancy of the price-conscious indian buyer!

[Tejas@perioimpl]

Mahindra does not invest in molding costs. they use what they have. that's why.

A friend is into plastics. His take is that the max of the piping as per dimensions and bends won't be more than 5 bucks a piece. That's ofcourse in a HUGE quantity and cost of mold not counted.

Your above two statements ^^ are contradictory my friend. Method of costing be it PVC, Plastics, Rubber, Steel etc remains the same; this consists of Man, Material, Machinery / facilities and overheads cost and then the profit margins. Yes, for mass production profit margin for single part is minimized. I hope it is clear now.

PS- In this case steel pipes is the best bet as standard sections are easily available.

Yup, they are contradictory to you Professor Spike. BTW, we'll take this off this thread. OK!! You are a genius in the making

Sorry for OT!!

Thanks to all you for giving me direction for choosing right material for my duct configuration. As more people are voting for Steel I would safely settle down with steel or stainless steel duct for my future snorkel installation.

Could someone through light on this topic as well ?

Shiva,
By th end of the day I think you will have the report ready with pics, if possible get the fully flexed pic too.

Is your 4-wire rims up for grabs? I shall take care of them like my own

I too will take care of them like, more than my own.

[Tejas@perioimpl]

I'd recommend trepadors or big horns. Good on and off the road. Don't know if they come in 30" size though. You'll have to google that.

For rims, I'd suggest the three spoke rallye rims painted matt black just leaving the silver lip unpainted.

Most probably yes. Let me see if I can pack that schedule in my today's todo list.

Those wire rims are not for grabs and they will be placed in my Jeep museum. May be when I wanted to show the Classic in its original face I will use it.

Sorry to you.

Ah.. the question is 15" rims with overall 30" with tyres and what would be the perfect width for my explorer?
