V8 trike build.

[graffian]

There was a yallow mach1 about with an electric water pump.
I was told the pump was a bilge pump from a chandlers?
All I could see of it was a hose nipple poking out of the inner wing.

 

[minimutly]

I always fit a small bore bleed pipe from the pump outlet to the header tank, even if it’s the length of the Vehicle.

That would depend on the type of header tank, pressurised or just a collector bottle thingy. I'm complexing how to bleed air from both high points of the system simultaneously.

 

[Morrisman]

So, todays contributions. I've put together the exhaust pipes to the rearmost silencers, mounted in the bed. Very close fit. But I'm stumped where else they could fit.

Theory is that with the fans running there will be enormous amounts of air drawn in all over this area, so the heat shouldn't be an issue. (there's also a fuel tank and tool box to fit in the bed.....)


Current plan is to angle the exhaust out the side of the bed, but i'm toying with running a sort of 'fishtail' out the back, narrow, to clear the rad.

I should have bought a narrower rad..... 1st world problems.

There is a gadget that will do the job, Landrover 300TDI has a similar set up with the engine being higher than the rad. Its a three port valve with a non return on the rad port. It will vent the rad when the stat is open and shut it when closed, this stops the waterpump pulling the coolant down in the rad when the stat is shut. the other port is from the head or in your case T`ed into the heater pipe loop. This will give you a constant restricted pump over ( purging) into the header tank when the engine is running

Too many silencers ? i went for some offsets to give me a quieter sound and dumped them under the axle, seems fine so far

I think mines too low for that mate.

 

[Morris]

I think thin fishtails would work well.

I was toying with just that same idea earlier. I can make them out of sheet steel.

Could you not use a generic over the axle exhaust? even if it means laying it over a bit to miss the shocks .

There's not enough room, with the axle travel etc.

Side exit and do away with the rear silencers

It looks very nice

Having put a bike through an msva, id suggest you build a system to pass the inspection, and one for later use! The one for the test requires a makers name on it!

After MSVA maybe.

Nah, the whole idea of MSVA is you're building a one off vehicle, so no way will they expect you to have a production exhaust on the vehicle. Besides, mine do have a makers name on:

Chucked in the old fuel tank off my last hot rod, seems to fit okay but the brackets are bent and it can be made to sit 2" lower. Looks like it might be a plan....

I noticed at a bike night last night how many modern superbikes have the silencers stuffed underneath the passenger seat. I don't really think the pre will be much heat coming off my red mufflers, to be honest. And if there is, heat proof wrap, all the trend nowadays.

 

[Morrisman]

Typing late at night after beer... should have said:

'I don't really think there will be much heat coming off my rear mufflers, to be honest'

 

[Morrisman]

Lots of fiddling around and reconstruction, and the exhaust system is basically sorted. Still needs some fettling but it's pretty much where it needs to be.



I was wracking my brains how to sort the passenger seat, with electrics box underneath, and ended up with this. The seat will be just a little bigger than the box, just to get it through MSVA as 2 seater. It can be improved/enlarged later. It's 2mm steel, and I practised my tig on it.....

Mounting it was the usual fiasco. perfect planning, leading into 3 sessions of cutting off and re-welding.... I don't want to break with tradition.

Your making a bloody reat great ding dong of this build. luvin it

And yes i am planning one now...if the bloody boat sells haha

i blame you @Morrisman
