If you have nothing useful to say about the thread at hand, then don't say anything at all.

How about this then I'll translate Bush65's words into MOFOlish from english


In this universe 5 divided by 2 equals 2.5

In a TT setup described

No:1 cylinder on the TD5 will be fed by No:1 turbo

No:2 cylinder on the TD5 will be fed by No:1 turbo

No:4 cylinder on the TD5 will be fed by No:2 turbo

No:5 cylinder on the TD5 will be fed by No:2 turbo

No:3 cylinder on the TD5 will be fed by No:1 and No:2 turbo. He's a greedy little bastard. He deserves a spanking from matron.


Now this is where it gets interesting.



For a practical experiment at home, if your a parent of one grab a toddler, bib them up (this will get messy) and put them in a highchair on a non carpeted room. Now get the other side of your toddlers gene pool commonly referred to as a parent and the toddlers favorite dinner. Let us name this toddler cylinder number 3, not the best name in the world, lets say he was named by Angelina (this is the way her surname should be spelt) Jolly or something so it will sound believable.

Cylinder number 3's parents Mr and Mrs Turbo believe little Cyl is too skinny and little so they want to feed him as much as possible. This is not usually a problem but due to them being a bit "you know in the head" Cyl's parents are trying to shove two little spoons full of goodness into Cyl's little mouth, at the same time. Little Cyl doesn't like the way the spoons shovel food faster and faster into his little gob and decides to chuck it all up and have a tanty. A very costly, time consuming five figure tanty.

It's the automotive equivalent of DVDA, google it, I don't mean the band.

1 big MOFO turbo I can understand. The head of the engine might not, but it's all for show anyway.

It would be possible to fit 5 tiny little escargot sized turbines with razor sharp fins puffing like an asthmatic cat in a vacuum cleaner bag is a but it's all for show. I can see this one working for 5minutes (it won't fit in the engine bay) but it would work till one little escargot dies a horobbleeeeeeeeeeeeeeeee deaaaattthhhhhh aaanddd thheeeee TTTTDDDD5555555 ssssooooouuuunnnnnddddsss likeeee aaaaa dddddackkkkk ddddddackkkk onnnnnnn aciddddd.


q: if I can produce an overspeed fault on a stock TD5 (and have the fault log to prove it) going down a long steep hill in 2h on 265/75/R16 and a 2T pay load pushing it. How the hell is the same engine going to handle a multiple turbine setup?

q: If someone else's chipped TD5 on a standard turbo can produce enough torque to twist maxi axles like platted pigtails on a girl guide why the hell would you need anymore turbines?

q: where are you going to remount the centerfugal and normal oil filters? Fit the larger or second intercooler? Oil lines etc?


In conclusion I'm filing this under O for Ogjonian in thought and implementation.

HAHA

This place just wouldn't be the same without you.

As you were...

Dammit Dobbo, now that is a low blow! It's like telling Yo mama jokes at an Orphanage!

The whole thing takes up a lot less space than a twin setup and if done carefully will almost look factory.

Here's my VNT conversion. http://www.aulro.com/afvb/projects-t...o-upgrade.html

It's got about 15,000Ks on it now and hasn't missed a beat. It's got no lag and makes plenty of power. Fuel economy is great too.


yer iv read ur thread on your turbo,, its a very very nice job, and seen it has sorta made me want to do this, very inpressed with the workman ship,
i just hope mine terns out as well
It's great fun to develop stuff and bolt on a lot of whiz bang parts but you have to be careful. You could end up spending a pile of cash on something that doesn't make that much improvement at the cost of reliability.
