Cobb Tuning Here I Come - This will be interesting....
You are correct. We just did a stock block car for TX2K that ran out of injector on E85 and ID1000's even with the fuel system, but with Alpha Turbos. We calculated his power to be around 850-900WHP, but had to turn it down for safety sake.
Every setup we have done thus far on E85 has had the BBI Fuel System even stock turbo. On stock turbos the 997 should be good with 1000cc's and stock pumps, but I am always for adding upgraded pumps as it gives some additional head room.
As I said I am up for it if you do
But we can always save it for later if you want. I am always up for a trip to Phoenix!

Mitch, who'd your lead tuner on the Porsche platform? I know Tim B has been traveling the country teaching Calvin and the Austin guys his stuff, but I dont see him listed as part of your Porsche expert group.

One of the best features of the cobb is you can remove the flash before taking it in for warranty work!!

E85 is essentially 104 octane.
I made 700ftlbs on my 996 with 1000cc injectors.
The 997.1 has two fuel pumps, so you don't need additional pumps like you do on the 996 unless you're going for big boy power (probably beyond 800 crank).
I figure 22-25% drivetrain loss on the 997. Therefore, I'd assume with 6 x 1000cc injectors in the 997, we could probably hit 775-800 crank with only an injector mod.
Thoughts, Mitch?
I may even be crazy enough to have those put in before you get here. LOL

Quite a few ppl run e85 in their 997.1turbos, no one has reported any issues with fuel lines afaik.
Yeah it's a factory system, going to try e85 later down the road.

Is it possible for them to know the car has had a tune prior to dealer visit? reflash will be evident and they can easily assume the car has been tuned specially if it has an aftermarket exhaust
