i am putting my setup together and i have a choice (it seems) to dump towards the motor or away from it.

where are your wastegates pointed, and are you using a dump pipe?

Thanks for the info.

 

Yes you should use a dump pipe. I had mine installed without one and it was facing the tranny/engine. I would get a lot of exhaust in the car when the wastegate opened.

Put a dump tube on it and direct it away from the motor and tranny.

 

I have my dump tube face towards the back of the car. Pretty much follows the direction of the downpipe.

 

direct it to the ground, its louder that way too im guessing

 

If you don't like getting pulled over, you should dump it into your DP. Venting to the atmosphere can be anoying as hell after a while. Fun at fist but defening in the end

 

I beg you, please, plumb it into the downpipe. Open atomosphere dumps are so ******* loud that, especially on rotaries, that I'm absolutely convinced it gives our 7s a bad rap. 99.9% of the population would not want to hear such an offensive sound. Open dumps do not help our cause.

 

"loud pipes save lives"

But yes, its very loud and sometimes scares other drivers off the road when it opens next to them.

 

ok cool, but does your wastegate have the opening for the dump pipe facing away from the motor or towards it?

the opening where the dump pipe bolts up....

 

P.S. i have to say that my friends open wastegate on his supra is pretty nasty...though an inline 6 is gonna sound better than a rotary most of the time....and passing people on 2 lane roads pushin about 450hp on 93 octane scares the bejesus out of them.

 

here but not permanent.

 

thats what i was looking for, thanks

 

Personal prefference. But mine is facing the engine. And plumbed in the DP.

 

I personally would route it into the downpipe if I had to do it again in a street/strip car. If you do end up venting to the atmosphere you may want to consider dumping away from the engine bay to reduce any further heat, and or soot. .02

 

I dump both of my wastegates straight down towards the ground.

 

Thats got to get loud as hell. I know its fun at first but after a while, don't you get sick of it

 

Yes its loud as hell, its still fun but I hardly ever drive my 7.

 

There is a third alternative you-all have overlooked.

Dumping back into the DP can cause a loss of power. Depending on the design, 10-30HP from what different tuners told me.

So you dump it to atmosphere but through a small ATV or motocycle muffler.

 

Mine is dumped to atmosphere, toward the ground. Loud it certainly is, but I've had guys I raced actually miss shifts because it scared the **** out of them.

 

ya same
mine dumped stright to the ground
i daily drive mine and full boost everyday im sure.
never gets tired and i love it!
