FBIS made some pretty solid numbers with shiv's turbo on his car with just 91+Meth+the new CEA wheel, he made around 550whp on a mustang dyno at 22 psi? His car is somewhere around Shiv's horsepower wise, so for manuals so far, this kit delivers some high hp

I know a lot of people want to and will run meth, but they also want to see what they can do without running meth all the time

Eh trust me, the company that will be doing this have their own shop for making their own manifolds, DPs, body kits, CAI etc. It not new territory for them and they dont have to depend on other vendors

Does this shop happen to be in the Northeast? Cause I think I might know who you're talking about.

His car just made 550whp on pump gas alone (94 octane), graph/videos to be posted soon. 654whp 94+meth

I saw that...good numbers...But not everyone has 94 octane available and a lot of people wouldnt want the hassle of mixing etc.

We do however all have access to 91 octane whether it is shitty cali 91 to NY 91 etc. That is what I consider Pump.

Props to shiv and FBIS...Cant wait to see graphs.

Anyways Back to Twins though

Predictions on timing of a full twin turbo upgrade being in stock and ready for order (not hybrid using original plumbing)?

The engine was introduced in Genevea in March 2006 and has been in the public's hands since fall 2006. Almost 6 years and counting....tick tock.

Hope you aren't referring to the picture they posted of their project like 1+ years ago. I heard it was put on the back burner.

Upgraded twins here as well

We are also working on new twins with custom made manifold for my n54. At this moment, not for resale purposes, just as a hobby.
Mostly we are using Garett parts, but they will be a kind of hybrid turbos with some "twin-scroll" effects.
BW EFR 7670 was my first choice to upgrade my n54 with twin-scroll turbine housing turbo and custom manifold, but BW was unable to delivery the proper twin-scroll turbine house for EFR 7670. I guess, that BW still cannot delivery it. So we switched and decided to go with two new single-scroll turbos. One of them is completly ready, the other is under machining.

On the other hand i think that among many things, the engine should be rebuilt heavily, when we are talking about 500-650+HP. It is not enough to use forged rods and pistons, but the heads should be ported properly and mostly the open-deck designed cylinders should be strenghtened as well. Many-many task, which i will do in my current project.

Sounds like a proper build. Which turbos are you going with?

You better throw some e85 in there then. Expecting huge numbers out of 91 gas is being a little unrealistic it seems. The engine is only 3liters and is high compression. I completely understand about not wanting to run meth, but you're going to have to have something more than 91 to really make a manifold and turbo upgrade worth it in my book.

What I would want to see in order to consider going twins instead of a single is something like two TD04 16gs like you see in the SRT4s. Something like that on custom cast manifolds from a place like Forced Performance would be perfect.

I was talking more in general. If I were to upgrade I would go mix some e85 with 91 but I was just make a general comment. I know only so much can be expected with 91 octane and high compression

I have attached some pictures about one of the turbo, which almost ready. Garett ball bearing CHRAs (will be the same on both of the turbos), Garett wheels (will be the same on both of the turbos) Garett M24 A/R .80 compressor housing (will be the same on both of the turbos), Garett turbo speed analog display, Garett turbine house for turbo nr1. (the other nr2. turbo will have smaller/different turbine house) and a total picture of the turbo nr1. Turbine housing on turbo nr1. needs some machining, otherwise it is ready. Turbo nr2. will have a little bit different/smaller turbine housing than this one, and therefore needs more machining to fit that turbine house to the CHRA. The wastgate on (not seen on the picture) turbine house nr2. will be enlarged a little bit and needs some machining.

My project is not about high HP (however we think we can do between 500-550, or maybe 600HP), but about the PATH, wich leads to a good result. Based on many-many good small ideas.

Are you aiming to do a sequential twin turbo system? I cant see using 2 different size turbos being a good thing on a parallel turbo system...

What are the goals here? I am a big believer is outlining expectations and having some sort of objective measurement of success beforehand.

I dont see there being a wide space to fill between something like RBs and the proven single turbo system. With something like this, you are going to end up spending way more than a single turbo upgrade with worse results.

Unless these are going to spool up 500 rpms sooner and make nearly the same peak hp, it doesnt seem like a good idea. Simplicity usually works best, and it just seems like this is making something more complex than it has to be.

P.S. I am no vendor fanboi, but I appreciate results when I see them.
