Now to the finer detail:

Does your "dredge" have a 3" breathing apparatus, because it does sound good. [img]style_emoticons/<#EMO_DIR#>/laugh.gif[/img][/b][/quote]

sure does mate [img]style_emoticons/<#EMO_DIR#>/laugh.gif[/img] [img]style_emoticons/<#EMO_DIR#>/laugh.gif[/img] [img]style_emoticons/<#EMO_DIR#>/laugh.gif[/img] [img]style_emoticons/<#EMO_DIR#>/laugh.gif[/img]

straight through at first [img]style_emoticons/<#EMO_DIR#>/laugh.gif[/img] [img]style_emoticons/<#EMO_DIR#>/laugh.gif[/img] but was to loud

so i now run a small hotdog muffler just to keep it under control :wink:

all for a total cost of around $450

for the inflowing gases mine has 3" to the airbox then 2.75 to the turbo then for the out flowing gases 3" straight through 8O

In an ideal world, yes. If you look at pure race engines turbocharged such as a Champ Car engine, they use equal length primary tubes, going into a merge collector such as this http://usera.imagecave.com/tdi-rick/4-1_25ds_T3-b.jpg which looks like this internally http://usera.imagecave.com/tdi-rick/cutaway_big.gif this provides a smooth transition for the gases, maintaining as much energy as possible which would be lost in a road car/box type collector. In Sports Prototypes and Champ Cars, the pipes are made from inconel, (an exotic high temp resistant alloy, and very, very hard to work), lesser categories use various grades of stainless steel, and are insulated to retain as much heat (energy) as possible to reduce spool up time (lag).
Also, generally, the primary tubes feed into the collector in firing order.
All of this is pretty much in order for a normally aspirated engine as well.

I shouldn't have read this article, now I don't know what to do first. dual battery set up or 3" exhaust. :? :roll:

Do you think a 3 inch would go alright on my 4.0 V8 Rangie or would it lose to much back pressure???

Who cares it would sound awsome. [img]style_emoticons/<#EMO_DIR#>/biggrin.gif[/img]

Seriously though, i'm not sure, its only a small capacity engine, but seeing an exhaust specialist would be the go. A larger exhaust and some pacemaker headers would make it go, and sound awsome. Matt

I can't wait to hear the sound of the V8 :twisted: . I was thinking of running twin pipes!! I havent been able to find anyone on the Gold Coast who can get a set of headers without custom making them. Are they available as an aftermarket item for the P38A??

Next project.......

3"..............




















might even do the exhaust.......

Sorry for my ignorance, but are we talking about a 3" system on a 300TDI ?

And this gives an increase in power and torque ?

As there is less back pressure the turbo spools up SOOOOOO quick.
