VTT S55 GC 93 Octane Results!

[Chris@VargasTurboTech]

We are very pleased to announce our S55 GC 93 octane results!

Working exclusively with Cary Jordan and using the Bootmod3 software from ProTuningFreaks we have surpassed all expectations and made 635WHP/691WTQ on 93 octane only (100% stock fuel system).

The car holds 600WHP to 7200 RPM. Zero fueling upgrades.

2015 F80 M3:
VTT S55 GC cast turbos
VTT Silicone Charge Pipes
Catless Downpipes
VRSF midpipes
Injen Intake
Stock intercooler
Stock fuel system (including lpfp).

For those who don’t know -these are new cast units, no core charge, no price gouging. We are offering a couple interesting package discount options with GC purchase -add a Spline Lock or Cary Jordan tune (OTS or Custom).

These will be in stock in approx. 4 weeks. Once in, they will be available for same day shipping. No long lead times; another one of the many reasons we call them game changers.


On to the graphs!

635WHP/691 WTQ

30 psi / 8 degrees of timing at peak power. 10 degrees of timing at redline.





Keep in mind we're intentionally slowing spool in these runs. The turbos spool very fast and come on so hard we feel its best to do so for engine longevity; but just to show you what we're talking about we have a graph from earlier in the 93 testing with spool not slowed.



We also attached graphs on the way to these results -this was not a glory run. Cary said this is a perfectly streetable tune on 93... run it!



E30 and E85 results coming up next!

Lookin Good!!!

Does this car has the crank hub fix?

[Commanderwiggin]

Needs a bigger turbine imo. Hate the power delivery, flat torque curve is much more preferred.

Make a single turbo bottom mount manifold with a Tial flange...I'd buy that. Would make it sound 100x better too.

If you want to exchange some response for top end power, that's exactly what you would do -but there are other options available for that. We sized these for good response and ~800 whp on a stock motor. If you want to hold the torque curve flat, and for instance hold 650 lb/ft to 7200 RPM... that's just shy of 900 whp -a different category of product (on 93). 450 lb/ft at 7200 RPM on 93 octane on turbos that are responsive, with this power band, makes for a very fun car. Lots of area under the curve for 93, and again, responsive. No lag monsters here.

A single turbo would be a fun project for some applications but that's an entirely different product/price range/end use.

Not yet, right now we just have the CBC installed. We'll do the crank hub fix soon, especially with ethanol tunes coming up next.

Ok to run this with cats?

If your configuration differs significantly from what we wrote up above I would just do a custom tune, but definitely ask Cary about that.

[Fast4d]

estimated price?

do the turbos need connect to OEM downpipes or do we need to buy new ones?

[Chris@VargasTurboTech]

We can't discuss pricing on this forum -shoot me an email (preferred), PM, or check out website.

Stock downpipes fit.

If lower to 26psi as CA gas is 91, what's the hp and tq?

Edit: Tony actually did run the car on the Stage 2 OTS 91ACN tune. Cary most likely could squeeze some more out of it, but ACN91 is very tough to tune on safely. The graph is attached. Sorry for the confusion.

I can " make" 93 octane up here in Denver by blending 100 and 91, but what happens if I just run 91 ( which is the same as 93 at sea level) with this tune? If I get it installed at the dealership can I drive it home on the stock oem tune before I upload the BM3 tune? Can you describe what is needed for Cary to do a " custom" tune? I'm very interested in this.

[Chris@VargasTurboTech]

Definitely talk with Cary about your particular situation at altitude, and if a custom tune makes sense for your application.

In general you can limp home from the dealership just fine without a specific tune but obviously avoid WOT until you're properly tuned.

[Chris@VargasTurboTech]

I've received a few questions about the S55 GC's and are they fully designed with our own drawings/etc. thought I'd simply and clearly answer that part publicly -yes, these are ground up new designs from our own drawings. Couple snap shots attached.

Built from ground up by VTT engineers?

Just like your Alibaba N54 Game Changers?

[Chris@VargasTurboTech]

A few guys are asking about logs, as is common practice on the S55, the tuner has all logs. Feel free to email Cary Jordan for log requests. We spoke with him about this and he'll help you out if you're looking for something in particular. Thanks!

We developed the N54 "GC" units back in 2012 from scratch working with our partner engineers. It took quite a while for them to be copied and redistributed. By that time, we had again completely changed the design and moved to another manufacturer. Those units are still uncopied. We understand this is one of the necessary evils of pushing things forward; your hard work will eventually be copied and mass produced. That part isn't fun, but innovating and pushing forward is.

Lol

Hopefully these last more than couple thousand miles

[M3anPower]

So much hate on VVT. I'm not going to get involved on that

But my question, Why did you guys asked Cary to tune your car when there are other trusted tuners world wide willing to help you with your product?
I have nothing against Cary but I'm going to be honest, never heard of him until bm3 for F8X showed up.

Cary was the tuner that worked with Eric, who is running our Stage 2's (ran a 10.2 1/4 mile!) so we looked into hiring him for the GC tune. When we did research we found he had a stellar reputation, minimal drama, proven results, and when we talked with him about the S55 GC project he seemed genuinely excited. That was enough for us, and we've been very happy working with him. Check him out!

Our 91 is 'standard', so a little better than the ACN. You could also run an E30 mix, which is what I've been doing for the past couple years. The stations with E85 are slowly disappearing, but there's a few still around.

I pre-ordered the turbos back on Black Friday. With these results on 93, can't wait to see the results on Ethanol...and get my GCs!
