I am in the final stages of putting the turbo system together in my car. I am running the turbo exh pipe out of the front of the car. I am thinking of running the wastegate dump tube into the turbo down pipe. Will this create any restrictions on exh flow or should they be kept seperate.

 

Cody at Lovefab is making mine with the dump-tube recirculated back into the downpipe. It shouldn't cause any restrictions.

 

Thanks for the reply.

 

It won't cause restrictions and it will help keep the noise down when the wastegate opens.

Restrictions? It depends on what you mean. Closed loop exhaust is a tradeoff, you sacrifice power for quieter (hopefully) exhaust in boost.

Does it really sacrifice that much power?

 

It depends on how the exhaust is made and a whole host of other variables. The only thing you can almost certainly count on is your peak hp will be lower with closed loop.

 

Its a track only car so I am not really looking to keep the noise level down.

 

Just make sure there is a very acute angle on entry of the dump into the downpipe. In other words, don't weld the dump entry into the downpipe perpendicular to the downpipe.

If it was perpendicular I could imagine it would blow the exhaust gases straight down to the bottom of the exhaust pipe kind of creating a "wall" that would block flow of the downpipe exhaust gases. Cody is making mine, I think he knows what he is doing.
