are thier problems in any way with having a dump tube thats 10 inches rather then 2 1/2 feet?

makes it dirty inside the engine bay if u dont point it outside and the noise

Its going to dump back into the engine back, resulting in your turbo sucking it up

is there an ideal length to keep noise down?

There's no rule that would apply to everyone, it would probably require some calculations that aren't really worth it, IMO. Shorter is always better assuming that you have gotten the exhaust to leave the engine bay. You don't want to exhaust in there, as was stated above, that's where your motor is breathing from, so you want clean air in there.

No but ideal placement would be under the oil pan to where the exhaust gases are being detered from your engine bay.

if you are worried about noise you should not run your dump tube to atmosphere, just get a married dump tube to your downpipe.

If there's a bit more restriction from the length, it will just open the WG valve a tad more automaticly. Unless you have serious problems, such as a 2" dump tube merging with a 2.25" DP and running very low psi resulting in mad boost creep, you should just focus on getting it away from the engine bay. As most people with good WG setups that dump back into the DP rarely have issues, I can't see a dump tube creating issues.

i had open dump....it gets kinda annoying....so just try and re route it back into the downpipe......
but then again i ran open downpipe also, and that was annoying, but it made a shiton more power and spooled so much faster i just dealt with it haha

hmmm, everybody says its loud by i have a friend with an lsvtec turbo eg and his dumptube is about 2ft long and its really quiet ive heard it at 7psi, ive heard it at 25psi its just no any louder than an na motor.

i guess the problem is what do you consider loud, to each his own on this one i guess...

Pretty much, every car I have driven or heard, usually the muffler is more of the problem with the noise.
