Hello all,

I wanted to officially show some of the things we have been working on at COBB!

For those that are not familiar with us, we are a tuning company that started in 1999 in Rockwall, TX. We are probably most well known for our Subaru support, but offer tuning solutions for multiple platforms now. We were the first company to design and manufacture a handheld tuning device for the turbocharged Subarus, the first company to crack the “unhackable” R35 GT-R ECU, and now we are super excited to be playing with Porsches.

Our most popular product is the Accessport, the most versatile ECU tuning solution on the market. It allows the user to flash the car with pre-installed Off The Shelf (OTS) or custom maps created specifically for your car by a local tuner, record datalogs to verify the car is running well or for issue diagnosis, view live ECU data, store multiple calibration files, record 0-60 or ¼ miles time, and read and clear codes.

Here are some of the latest developments that we have been working on:

E85 Tuning- We have been working with BBI Autosport and have made great headway with E85 tuning.



This is a 997.1 Turbo with BBI’s E85 package and the COBB Accessport. This is on stock turbos and Injector Dynamics ID1000 injectors. We have a vast network of tuners that are now Porsche Pro-Tuners meaning that now custom calibrations can be done easier than ever for your car no matter which fuel you would like to use! You no longer need to wait days for a file to be emailed, custom tuning for your exact car and exact modifications can be done live on the dyno immediately after Accessport installation. We are constantly updating our software to expose more logic and tables to better help tuners make the best possible calibration for your car. For example we just released some tables to help tuners tune injectors as big as 2000cc!

Those that know us also know that we like to do custom coding to be able to support big horsepower.

That is why we are currently testing MAF-less tuning, which will be available to all of our Pro-Tuner network in the very near future.

Here is a car we tested yesterday:

MAFLESS 997.1 Turbo, Alpha Turbos, ID1000 injectors, AWE Intercoolers, BBI Headers, MS109 Fuel (Low

Boost, High Boost)



The customer has 3 different calibrations all for one fuel that he can change in a matter of seconds at the racetrack.

The latest updates also allow tuners to custom tune not only the GT2 but the GT2 RS as well! So for those that would like to make their GT2 series cars faster, the Accessport is 100% capable of doing anything you could want.

Thanks for looking and if you guys need anything at all please feel free to email us at Porsche.Experts@cobbtuning.com or vist our website and see which Porsche Pro-Tuner is near you!

Hard to see in the second photo, and not indcated in the first image...What kind of Dynonometer are you using? Is it yours? And I assume that is at the crank? As you typically lose 20% +/- on AWD vehicles....Curious to be clear what you are trying to demonstrate here....It appears that would be about 495 BHP....

Also looks like customer had to install new injectors to get to that HP level with your E85 tune...Is that correct? That is a hefty $$ upgrade....

Thanks for the additional info.

We use a Mustang dyno, the power is to the wheels and yes it is ours. ( We have 4 Mustang dynos between our 4 facilities)

Yes you would need to upgrade injectors in order to safely run E85. We always recommend Injector Dynamics.

Thanks!

 

Wow...So you are saying with just your E85 Tune and injectors you are creating nearly 750 HP at the crank...

Hmmmm

Thanks for the info.

Dont think one should try to "convert" whp to bhp, its just a guessing game anyways. Ie there is no way one can use a fixed % to convert between whp and bhp, even if you see a 20% on a stock dyno run, that 20% is prob. a sum of a fixed max friction and a %.

And when you see bolt on AMG claiming 740+ BHP with canned Kleeman tunes and they still run side by side on the highway with simple 335i's who are just above 420whp something isnt right...

I rather look at gains from a stock baseline on the same dyno, but in this case over 600whp with a small set of mods is very impressive. I would want to see a baseline in the same chart though...

 

You can certainly have your opinion....

You reference two separate issues here:

The first is the HP claims. I would not call it "guessing" as the experts widely accept the HP loss at the wheels for AWD cars at "about" 20%. Not exact....that is why I stated about...But again, widely accepted as an accuarate estimate measurement....which is what I was stating.

Your second point about various HP cars running side by side is simple. You are overlooking all sorts of variables. It is not just HP...Speed is a factor of MANY variables...HP is one, TQ, Weight, Gearing, N/A vs Turbo / supercharging. So it is not uncommon for less HP cars to be faster that higher HP cars....

So my only point was...using widely accapted estimate of 20% loss at the (4) wheels. The indication would seem that injectors and a tune yields about....750 HP. If you read enough, you will see that that seems incredible for these cars.

Anyway....clarifying what I was stating. And yes, it was an estimate.

Stock turbos maxed on E85 do yield what Cobb is showing - ~600+whp or so. They do use mustang dynos, though they are not of the 'heartbreaker' variety and typically read closer to dynojet numbers.
Rix has a nice thread here where he got a proto E85 tune on stock turbos and has a cobb dyno plus a dyno from another shop so you can see the differences. And on an e85 tune with just injectors and .2 ICs, I ran a 6.8 60-130, which again equates into that 600whp area. I moved on to add larger VTGs and upped the power quite a bit as well.

So yes, E85 is magic and really will produce those numbers.

 

Ok, I "guess" I'm not a fan of the imo unecessary "conversion". And I seen "estimated" losses ranging from 15-25% there is actually a site (rototest) that compares measured and claimed HP, http://rototest-research.eu/popup/pe...p?ChartsID=785

So either the turbo has 460hp x 1.2 = Well over 500 hp or the losses are much much smaller, or?

I am sure my MT has less losses than a TIP or a PDK as well, but isn't it simpler to just drop all BHP claims and use whp?

And E85 was "magic" in the 335i and I am sure it will produce amazing numbers in the p-cars (already proven by Protomotive/Todd?)

 

750 x .80 (20% Drivetrain Loss) = 600 WHP. Which is basically what Protomotive has already done on a car with less mods. The aftermarket Y-Pipe is most likely responsible for the ~20 HP difference between the Proto Stock Turbo/E85 setup and the BBi-COBB Stock Turbo/E85 car.

More than likely both cars are running similar boost curves (their OEM VTGs), but BBi probably has access to better quality E85 (since they're in Cali) which allows them to run a slightly more aggressive timing curve, in addition to having more supporting mods.

 

Here is a stock 997.1 versus the car on E85. Hope this helps a bit.

 

e85 is crack on our cars - that has already been proven by lots of tuners. I think the numbers seem credible.

Welcome aboard cobb!

 

Interesting

 

I really want to turn my tt into a enviromental-friendly car now

 

9 mpg on a decent average run day

 

Managed 3mpg on track on average over 3 tanks
