MAP will make one for you with a v-band clamp in the middle so this is no longer an issue.

I talked to them about this and they are going to make one for me. That's what I'll be putting on this spring.

You will make a lot more power on pump and less likes to knock at max engine load. A Black snaps when it get's into boost, so it'll give a lot of load and back pressure, you will have an extra .5 inch of flow plus the dump to control boost and to direct exhaust out of the downpipe for more flow.

The donut area is indeed stock sized. Why not get one of my pipes? I have a used one which has about 1000 miles on it and a new one. I plan on a 35R shortly so I have no need.
Is your o2 wastage dump 3D contoured to match the shape of the turbine housing? or is it just a round circular shape? Thanks

I'm talking about this one specifically:

I fyou are refering to the one I run, it is a simple dump that goes straight down and is about 2 inches in thickness. The pipes shown are all hand made and welded so It is simple exit and designed to be a straight as possible but allow fitment avoiding the Lower IC PIPING and so forth.

Bill said the v-band clamp might have to be lower, but they said it would work. Have to love the guys you work with! Good bunch of guys over there at MAP

I'm excited to see it too. I'll be calling Bill soonish to order it

Hey Bink I think might be doing the same thing as you I really want a true 3" but im not sure what exactly your asking Chris to do for you. Correct me if im wrong... Your asking MAP to put v-band clamp below the are where the dump tube finishes so when removing the downpipe you dont have to remove the whole entire dump+downpipe? If thats the case I might like that idea too if the price is right.

Exactly!

If I want to remove my down-pipe I don't want to do an O2 housing job every time. This would allow you to remove the down-pipe and keep the O2 eliminator attached to the hot side of the turbo.

The v-band clamp would be low enough to the clear the dump but still high enough for enough room to work.

As far as pricing is concerned I would contact Bill@MAP and tell him I sent you. He'll know what your talking about.

Thanks Bink I'll make sure to email him. Let ask you another question am I really going to see that much of a gain coming from a Megan 3" downpipe with a jm fab o2 dump to the MAP true 3" exhaust with dump? Right now on the stock turbo but I'm planning on getting an Fp black when I get my tax return. Let me know what u think

NP man

To be honest, that's a pretty good exhaust setup you have already. The JM FAB O2 dump is top notch, Aaron@English Racing loves them.

The only real difference is MAP's is a 3" while the JM FAB is 2.5".
On the stock turbo, there probably won't be a measurable difference. On a FP Black you will probably see a few more horsepower...how many exactly I don't know.

That's a good question to ask MAP when you call them, see what they say. I would assume their answer will be along the lines of what I just said though.

Again thank you Bink!

Well, if your planning on making that kind of power, the bigger down-pipe will definitely help.

What fuel/motor are you planning on running?

Anytime!

I would love to make 650 on 93 pump but I know that's wishful thinking lol Im thinking E85 will be my fuel of choice to make those kind of numbers. As far as motor goes I wanna keep it 2.0 I still haven't looked into what parts or brands for the rebuild or who is doing the build but I know when the time comes I'll be back here reading and asking questions

Unfortunately, with the FP Black and 93 pump, 650 WHP won't happen.

I made 466 WHP running 93 pump on a mustang dyno, which is roughly 520 WHP on a dynojet. This was on a built 2.0, ported head, ported intake/exhaust manifold, running 34 PSI boost which tapered to 29 PSI by 8500 RPM.

I'm hoping to make 580-600 WHP on E85 running 40 PSI. I'll probably only run at this level while racing, on the street I'll probably take it easy. I have a feeling either my tranny or transfer case won't last long at that power level.

Also, be prepared to drop big amounts of money
