Re: alternative location for wg
 

but does it really matter how efficient the turbine wheel is when the wg is open? when the wg is open, exhaust gas will be exiting through both the turbine and the wg because full boost has been reached- so why would it matter? i would imagine you'd want your turbine to be as efficient as possible when trying to attain full boost, not as critical after the wg is open. am i missing something?

if you are refering to just the fact that the shape of the pipe will generally create turbulence due to the wg's proximity to the turbine then yes, perhaps it might, but the transition is so smooth i can't see it being that much of a problem on a car that will probably only see 8psi. on a car that is seeing 25+psi it may have more of an impact, but then again, cars running that kind of pressure usually have open dump tubes don't they.

Turbine efficiency is ultra important always. If your turbine does a poor job displacing exhaust then there is a significantly higher chance of reversion. You are increasing back pressure right in front of the turbine. This makes the air not want to leave the exhaust manifold as much and when it does, it cannot leave as quickly because of the WG dumping into its path. I'm not saying its going to cost a lot of horsepower, but I'm fairly certain if you routed it into the downpipe further back, you would see an increase in power.

That is a nice piece. good job.

oh god damn why does there always have to be the one hater. shits pimp, its probably going on a street car...i promis it wont make that much of a difference... bitchin ass manifold though boss!!!!!

As always, Nice Work Aaron. We have to come see some of this work in person soon!!!

As to this, we have 4 PF Engine stans for about 3-4 year with not problems. Princess Auto is the ----!!!!!

Correct, a friend with a gt3076r on his srt4 noticed the same.

With the wg dumped into the exhaust closer to the o2 housing area... (I guess the first bend in your downpipe off the flange)... It actually sucked away 35whp because it was creating turbulence in the exhaust.

Remove the merge into the exhaust.. picked up a muffler that they put on 2 stroke dirtbikes... and ran the wg dump through that muffler and out... quieted it down.. and he gained that 35 back.
