route the WG dump back into teh down pipe or exhaust.

i left it open on ym first turbo build on the m3 and it sounded like ****. and way too loud.

if you route it back into the exhaust at a direct 90 degree angle you will cause turbulance in the exhaust flow.

always route your dump pipe back into the exhaust at a angle so tha the dumped exhaust merges into teh exhaust flow smoother and also teh exhaust acts as a vacuum helping to pull the exhaust fromthe dump pipe as well.

ding ding ding, we have a winner. You can actually use the recirc to increase velocity in the air mass of either the dump tube or the main exhaust depending on which has the higher velocity at any given time and the angles you use. That's part of the reason my exhaust starts at 2.5" goes up to 3" and then I run a 2.5" muffler. By the time the exhaust has reached the 2.5" muffler it has lost a good bit of heat, and because of that volume, so the restriction acts to speed up the air mass, help retain velocity, and create an area of lower pressure at the end of the exhaust via the venturi effect, or I'm completly full of ****.

nothing about this downpipe cost me power. It's idealy recirculated 16 or so inches away from the turbine outlet and is merged smoothly back into the main pipe just before the next pipe. Once I step the next pipe up to 3" it should work even better.




Open dump is somtimes, to some people, just turbo car rice.

x2 , it sounds like ass...

why are people saying leave it open?
