external wastegate placement

[brian89gp]

I have seen a few external wastegates hooked up to only 1 bank of cylinders. I can understand it due to engine bays never being large enough, but how effective is it?

Dang, that's a tight packing. I don't know if you can put it in like mine is.....

Take a look at these (Under Pics)

I'm not sure if have room in there I would try to set it up more like that. Do you have any room in your quarter panel for a filter?

[brian89gp]

Probably not. The one I have now has an internal wastegate, the turbo that I want doesn't.

There is an A/C canister pretty much right below the turbo and tranny shift linkages filling up the rest of the area underneath. Not much room up top either. I can do it to just one bank fairly easily, both banks is possible but much more difficult. I got a DeltaGate and the thing is huge.

Yes, I have room in the fender for a filter but its not going in there. I had one down there originally but every time the pavement got wet so did the filter, the turbo would suck a low pressure area and the oil out of the seals mixing it with the water rather well to make this white greasy mess. I poured more then 1qt of water out of my IC piping more then once.

Hey phantom505, where did you get your washer fluid and coolant tanks?

Coolant? That's still stock.

Washbottle hasn't been replaced yet. Those are for the alcohol injection. I might get around to it someday....

[Lyle's GTP]

Alcohol injection! Sweet!

there is plenty of room in a w-body for a external gate. we also used a turbonetics delta gate on tims and ran a dump tube to the ground in front of the transmission past the A/C reciever dryer behind the radiator. there is plenty of room.

you can also dump the outlet of the gate into the downpipe so that it bypasses the turbo. that is how its is supposed to be done. that way you are running all exhaust gasses through the cat and making the air clean for everyone.

you want to hook the gate in where the x-over collects. if you run it on one bank or the other it will cause you to go leaner in on bank or the other. so it is best to put the gate right at the collection point.

Ok, thats what I was wondering. Its a little more difficult on a 5spd because of the shifter cables and brackets that take up more room.

That dump tube, how loud is it? I've heard that when it opens it sounds like straight pipes.

some cars its loud other cars you can barley hear it. tims monte you can't really hear it. keep in mind its only like 1.5" diameter.

I just ran across an image of TimG's car, it looks like the gate is on the rear bank about 6" before it collects at the turbo. Hows the car doing, how steady does it handle boost this way?
