Pipe for turbo manifold 4AGE Tue, 06 July 2004 01:40 Go to next message
I can get bends off someone - for bottle of whiskey. Hi quality steel. Can get in a few sizes but all are 5mm wall thickness. Would 1 1/4inch be ok with that wall thickness (Not sure if 1/14 inch is the OD then you minus off 10mm to get inner diamter? FOr 4AGE Turbo exhaust manifold
I realise this is heavy - but I don't really mind.

I've heard that if you speed up the gases a bit here you can spool up the turbo quicker...don't want to restrict the flow too much though

Just checked with the guy..it is 32mm Id the pipe. Thanks Dale for the speedy reply. How many bends do you reckon I will need. I can get 45 degree and 90s.

Also for dump pipe - should this be 2-2.5 inch. My exhaust is standard but I might make dump pipe a little fatter just in case I decide to upgrade this.

just get 90deg bends and cut them up for the smaller bends, we generally used 8 bends on a starlet manafold and 6 on a 4age manafold,

do the dump pipe in 3in and merge it into the stock exhaust,

Thanks again Dale - you're a wealth of knowledge Shocked .

How thick do you think the dump pipe has to be (i.e. wall thickness). It's the manifold that's the most crucial one isn't it? (Cracking etc)

Thanks

for the dump pipe just use ordanary exhuast mandral bends, any exhaust shop should stock them, if your near castle hill in syndey pop into castle hill exhuast centre, dave carries all that stuff in stock up to 3.5"
