I was going to make a post about that mani...but well I'm lazy

That car is very nicely done...Mad props to him for that work.

some guy at englishtown had that same manifold but for a 4g, it does look real sick

looks like a sidewaiz header.

I would say the flow to the turbo on that thing would suck. All the exhaust gases are directed and forced towards the waste gate. I would venture to say that even a log style mani would flow better....just my .02 though. :shrug

*edit*

it seems like they could have done a little better with some 90* elbows at the turbo side and had a much simpler collector and then just moved the WG down a bit. I guess it's not a "bad" manifold...I would just change some things about it...but what do I know? LOL!

After looking at it again it looks like a 4-1 header modified sideways. It doesnt look like it flows very well.

there is no way in hell that thing even flows worth a shit...:thumbsdown

Yeah, I'm going to have to agree with tim. It seems they had the fab skills, they just didn't design it good.

mine is much better.

I love the oil cooler though.

I thought that's what that was...thanks for confirming :)

Pics?

<bangs head on desk>

That manifold is awesome. By favoring the wastegate, exhaust gasses have an easier time of bypassing the turbo, which is better for boost control.

Porsche has claimed that the 964 Turbo had a pumping loss of 20HP through the turbo. In other words, it only takes 20HP to spin the compressor and make positive manifold pressure. What happens to the rest of the exhaust?

Much of it goes through the wastegate. This isn't perfect, though, as a wastegate can only pass so much exhaust, so people run bigger exhaust housings. To not do so is to encourage boost creep.

What if your wastegate were able to pass all but 20HP of exhaust? You would be able to run a small exhaust housing, giving you the same amount of power with a bit less lag. This begs the question; why not aim the exhaust at the wastegate?

Before the wastegate opens, a high-pressure area develops in front of the wastegate valve. This high-pressure area is right by the exhaust housing inlet. Being that the housing can be so much smaller, flow isn't really a problem. The turbo will come into boost more quickly, and the WG valve will start to open, closed loop. In other words, it will only open enough to vent enough gas to attain the set boost level.

If space constraints allowed, I would run the wastegate and the turbo almost collinearly. In other words, I would aim the collector right at the wastegate, and then have a branch at a light angle off of that where I would mount the turbo.

This manifold is the first decent (in design, not construction) manifold that I have seen for this platform. The old turbo Formula One cars had a similar setup, actually.

With a quick search I found this engine bay of a 1988 Ferrari. It seems like it has the traditional turbo setup, not like what you are mentioning. I'll keep searching to see if I can find some better pics:

I can't remember who had the WG-at-the-collector setup in F1, I will do some looking around.

Here's a late 70's Porsche



Wow look at this one!

I have seen "right" things in my life ^^^^ that is not one of them. I mean that in a good way.

Soon my frend soon. BTW did you get you car back yet I am curious about that turbo. how it reacts with the 2.0

I wish, the little things are slowing me down and I have to wait for John Reed to come back to finish the EMS tuning with the new turbo.

It says the car is in Florida yet the plates are Cali?

yea, the car is in Florida, he just hasn't updated his information. damn, this guy literally lived like 10 minutes away from me, I would have loved to see that setup up close

A friend has that same manifold in his sentra, they don't have any other choice, they have No room in there for a traditional manifold.
