The V8 Owners Forum -

So.....as someone stated earlier steering can be useful so I got the car back over to Wayne at www.custom-garage.co.uk

then things started getting interesting.....


just look at the cool exhaust Wayne made for me!

it fits just right in here

then a pair of rads to go with the intercooler

this is my favourite one



I had to get a doctor to remove the grin off my face!

Again super happy with Waynes work, now have a long list of little jobs to do

Holy crap
That is an awesome set up.
Methinks that might be a bit swift when finished.

Great work and keep the pictures coming

Lots of nice work going on, although flow path to the wastegates is a little odd.

How come you didnt keep all the hot pipes low and come into the turbo from underneath ?

Thread hijack and sorry to JJ for this
Steve did you get my E mail please?
Hijack over
Cheers

I did thanks Paul, just been very busy, gave a quick reply just now.

Cheers gelmonkey, all credit must go to Wayne i just told him where i wanted everything to go!

Its probably a bit tricky to see from the pics both banks feed into the offside the wastegate is on the nearside single vband. Im happy with the exhaust as its not a 2000hp full on rip yer ead off race build, i will be happy as long as it makes 500 which will be more than enough to start with. I want to try and get the car about 1200kg and not push the engine too hard as i want to try and keep "some" reliability hahahaha

I know the engine is solid mounted, but i would of thought you would need a flexi in those feeds from the headers - due to heat expansion etc otherwise you might start getting stress fractures.

I can see the routing ok....just that the flow path isnt smooth to the gates, as both almost need to make a u-turn prior to the turbo flange.

And Eliot makes a good point, that's a lot of pipework there with no ability to move, expand or contract.

I see your point ill ask Wayne to redo it in the new year.
Do you think, if it'll fit, placing the wastegate horizontally and nearer the flange would help?

It's all about flow.

You'll see people talk about creating flow priority for the gate or gates. It's basically just ensuring a free and smooth flow path to the gate.

With your current setup....the flow will not be smooth. A simple modification where it does that U type 180 turn to get to the gate would make a big difference to flow

That said, the only negative effect it will have if flow is not sufficient, is too much boost. Usually in the form of boost creep as rpm's rise and/or a higher low boost target than you had hoped for.. But the pipework looks to be a fairly large diameter, so because of that, it may well be fine.
By that I mean the pipe to the gate looks to be same size as the pipe feeding the turbo, not smaller. So it should be able to leak off a considerable amount of air despite the flow path.

TBH I'd have just thrown a pair of gates onto it, one gate on each pipe prior to the turbo. There's no lack of pipe to install them onto it, and that way would also simplify plumbing.

What size is the gate you are using ?
