Getting Exhaust done (and turbo discussions)

[shadowmaker]

Gt2260v gives about 1,5bar already @2000rpm and spools around 1400rpm in a 1.9TDI. A good turbo for 2,0bar and ~250bhp in a 8 valve setup.

According to Garrett studies ball bearings have more drag after 120krpm so not ideal for vnt. For better spool up why not.

i think i'd be keen to just keep going with the vnt15 (i think they're like 1300aud) as opposed to anything larger- i dont like the idea of TOO much lag, and i have no specific HP figures that im aiming for.

god knows i really dont like the idea of too much wheelspin on a daily. i think vnt15+remap+smart spray systerm+turbo back will be enough for me to have fun without driving becoming tedious or dangerous on icy roads after a day up on the hill(me=tired).

additional funds are gonna be redirected towards suspension & additional sets of wheels.

a big turbo sounds good, but i kinda like the idea of using a vnt15 to capacity (once ive got above mods) and it being fun, rather than having a 17 and having wheelspin at part throttle on wet/ icy roads.

but josh, i will be glad to watch your endeavors with a big turbo, if thats what you're going to be doing

You'd be very happy with that Scotty. Same old turbo tricks, even more necessary in a diesel. Air in, exhaust out, keep it cool, up the boost.

When you go beyond injectors, and start swapping turbo's I feel you enter the danger zone. Fine if you have a backup car, not so good if it's your daily like me.
Perhaps one day I'll go to the dark side like you Shadow, and become seduced by the evil ways of the boost.

I know I'll be happy with what's possible out of the vnt I have for now.

cheers for the info man, its hugely appreciated.

i definately dont want to compromise any aspect of the car being a reliable daily, and a daily that keeps going and going and going, at that (with regular maintenance etc etc).

ive only ever driven petrol before, and im addicted to diesel torque, so the icing on the cake will be the few modest mods i've listed above.

cog, are you chipped?

[Greg Roles]

Nope, it's the last thing I'll be doing, but it'll happen.

Those are the kind of numbers I want Shadowmaker!

Can you please tell me what other mods will be needed to get 250hp out of the 8v TDI?

apparently these axr engines are pretty tough (i think i read that on the club).

wouldnt it just be a matter of stuff like this:

-turbo back exhaust
-front mount intercooler
-bigger turbo
-pd injectors from kerma ($400usd for one!!!!!)
-bigger intake manifold (like from pd150 aka gt tdi golf)
-bigger airbox with maf from a more powerful car, i think?

dunno exactly how many hp that would yield, but i think perhaps thats some of the stuff you'd be getting involved in, maybe?
