badass custom twinscroll manifold, DP,WG, GTX3071 Turbo set up
 

I have a custom Twin Scroll Turbo manifold & Downpipe.
This only has 1 dyno session on it. I didnt have time to dial it in and it wasnt where I needed it to be for my drift preference.
I am working on a new project
The Exhaust housing is from an Evo X. It is a .73
The turbo is a GTX3071. Yes, GTX
The WG is a Tial MV-R(newest 44) It is to atmosphere
All Vbanded except housing to manifold
This is a serious piece

I couldn't tell from your picture, but will it clear stock PS pump ?

^^ Good question, I dont know. I dont have a stock pump. I have an MR2 electric pump.
It is in the location of the old pump, but I didnt fit it to a stocker.

If someone local wants to slap it on and see, thats cool.

Most track cats dont run the PS anyway.

I apologize for not having a better answer

Check this pick out. I can measure how far back the electric pump goes back.

That should give you a good idea.

Yep, That's the picture I saw. I knew it's not the stock unit that's why I asked, but I think it should clear the stock one as well.

Wow killer deal, sometimes i wish i had a real job lmao.

Yeah, if someone gets a pic of the stock set up with a ruler or whatever to see what we are working with I can do the same to see what we have..

Thanks everyone...

So where did this end up spooling exactly? I'm looking for your dyno plots and don't see anything posted.

I dont even remember. Let me try to find one. I never posted it because it wouldnt represent what it could do up top. The effort was to dial in the bottom end. never touched the top at all...
Let me try and find a plot.

Sorry I couldnt find the file. This video shows the dyno plot.

Hope that helps

Some jenky test and tune in there too LOL

That would be 398 whp and 364 ft/lbs of torque....holy crap! For those curious, but short on time...this starts spooling at 3000 rpms making 160 whp by 3200 rpms, and fully spooled by 4000 rpms and beyond 370 whp from 4000-7200. And this was before you completed tuning? Wow! Love this setup, what kind of numbers are you hitting with the 2871?

How many people have over and over said that turbos that big don't make power down low? I'd say 360+ ft lbs by 4500 is pretty much getting all of it down low.

Holy shit. Good luck with sell!

The fact is, this setup is pulling harder by 2500 rpm than an Mp62 supercharger at full chat . Big turbos make big power everywhere...

Uhh...I don't even see 100 whp by 3200 rpm.....:facepalm:

Turns, what are your engine specs? Dispacement, compression, headwork?

160 ft lbs. @ 3200

Still impressive.

Quick Spool Valve could work with this turbo, altho it looks to my noob eye that it doesn't work with the manifold.

Wrong. QSV needs a open collector and this turbo's flange is not T3, T4 or T6 footprint. Also, more importantly, it's not needed.

Let's say I only wanted 300 now, but 400+ later, would this setup suck untill I'm ready for big power?
