Wastegate blowoff....

Right now my wastegate is venting to the atmosphere and I'm wanting to route it back into the downpipe to quite it down some under boost. Any pro's or con's to venting into the downpipe?? Opinions?

the pros are faster spool on shift.
the cons are slower turbo response on shift.


every time u shift the turbo has to respool. venting it hurts that. piping it in improves response and turbine efficiency.
i vent mine FOR the sound.. and im an auto so theres no losses. hehe

I have heard of a muffler for the wastegate, never seen one in person though.

What are you talking about? We're talking about the wastegate, not the blowoff valve right?

I made one for mine, but to be honest, it didn't quiet it down that much... plus I'm having some boost creep issues... I'm gonna remove the muffler and see if that solves my creep issues and if so, will probably consider having it routed back into the downpipe somehow because I don't like the extra noise at WOT. The reasons I think mine doesn't muffle very much noise is I used 1-1/2" inside and 2" outside. That only gave me 1/4" on each side of the inside pipe to fill with steel wool. I drilled holes in the inside pipe. I also had to put a little kick where the muffler meets the flange because it would have hit my crossover pipe. I think the exhaust energy is hitting the muffler at an angle and causing too much backpressure, hence the creep. It sure looks pretty though, right? LOL!

is your wastegate angled back against flow. i guess it looks like it to me. if so, boost creep will happen.

I guess I'm just not following what you're saying. The OP asked about what the pros/cons were to tieing his wastegate discharge into the DP. How does this have ANY effect on performance? Exhaust energy is being vented.... whether it's vented to atmosphere or back into the DP shouldn't make any difference on spool... am I missing something? No one was talking about the BOV, so I'm not sure what that had to do with anything... BTW, I'm not trying to be a dick, just trying to figure out what you're saying.

The wastegate is in the standard location and angle provided by B&G. I had to angle the muffler just a bit to avoid hitting the crossover. You'll notice that it's kicked a couple of degrees out from 90*.

tying it in hurt power by 20-35rwhp depending on the motor.

That's the kind of info I was looking for. I had read on some other forums that tying it in hurt HP. I was just curious if anyone had some real world trial and error with this. Thanks for the responses

The Turbonetics Evolution external wastegate has been the choice among racers in all industries. We needed a way to properly manage the exhaust flow to the turbine as to prevent any unwanted boost creep, but still allow enough control for those wanting to put the engine to its limits. The Evolution gate does this perfectly with a few different spring rates (all spring rates included in the kit). We vent the external wastegate to the atmosphere to keep turbine efficiency the highest as possible. We don't want wasted gasses and turbine gasses to fight each other downstream and create unwanted backpressure. However, we do understand that a few customers want the opportunity to keep it quiet and don't care about a few lost ponies, therefore we can vent it back in to the o2 housing at an additional cost.
