Just wanted to let everyone know, we are fully stocked on the Stainless Steel Investment cast turbo manifold! Stage 4 kits are in stock, and ship within 2-3 business days.

I was talking to a friend of mines here who owns a shop and works strictly on Evo's and Sti's, He was an engineer for Subaru in hes early ages and He mention that by blending lets say 1 Gal of E85 to an existing Chevron gasoline that contains 10% already could give you the wanted E20 mix. and promises no Knowck issues and getting more power/ft,tq then straight E85...!!!!! How much true that is I don't know since He docent know much about our cars.
This part of the conclusion of the study in the pdf posted in this thread
"Intermediate blends near E20 can provide the majority of the
performance benefit of E85 and enable strategies that offset
their lower energy penalty."

Once you pass around 40-50% ethanol content the gains are very minimal and really not worth the strain it puts on the fuel system.
Most people run E 35(1:2), 47.5(1:1), 60(2:1) or 85 due to easy mix ratios

I was actually put on Hold on further testing's cause I was going to sell the car, however after talking to the wife for several days We desired is in our best interest to keep the car since its going to be paid off in less then 6 months.
With that say I'll be getting back to Joe and continue with the tuning. So we should c new numbers next week.

Has this been confirmed does anyone know??

^^ this
The only real benefit of running anything past a 50% e-blend seems to be the cooling effects that the ethanol has in the combustion chamber.
I know this chart is part of the delphi study pdf, but it is a quick referance to showing just how minimal the gains of going from e50 to e85 really are. I kind of wish the chart actually included a 20% eblend though

not to be a *******, but why spend all the money to basically just flip your hp/tq numbers?
most bolt-on tuned lnfs are around 325whp and 375wtq. now you have 365whp but only 339wtq...
the only way i would spend all that money is to have a perfect balaced power @ 400whp/400wtq+ numbers...so i dont see what all the rave is about right now...please prove me wrong here

If you want a turbo that does 400/400 id suggest the bnr2871.

It's not all about peak numbers. A stock turbo car may make 340whp and 400ft lbs, but all that is is a spike. The stock turbo will make that and then fall off due to restriction (backpressure, compressor efficiency, flow capabilities, heat, etc).
A well-tuned car with a big turbo isn't going to spike like that, but make power a little slower and maintain that airflow with a much higher efficiency farther into the powerband, holding boost and torque to redline.
Which is why on a big turbo dyno graph you'll see the hp number continually climb as it holds torque and rpms increase and on a stock turbo dyno graph you'll see a big spike and then both hp and torque fall towards redline.
Tl;dr
20psi through a fire hose vs 30psi through a garden hose.

Because the big turbo is making 365whp at 6-7k rpms where as the stock turbo makes 290ish (if that) at 6-7k rpms.

^^ agreed
Remember, this car is making that power, on 93, with no spike, on 21 psi. More boost, more octane, and this thing will clear 400 with room to spare, and carry it to redline.
I've tune this and stock turbo LNFs, this car has a much more usable power, it is't spinning when the turbo spools and then falling off. It spools and pulls, all the way up, smoothly. Next gear same thing. You don't feel that spike that makes you think you are going faster, the car just builds speed steadily. More area under the curve wins races, not spike and fall.

understood...i think if tuned properly, and ive seen a few stock turbos that hold power great on the dyno numbers, but obviously they are maxed out...
i am not knocking treadstone or anything, i was just trying to see why this kit was worth $3,000..thanks for the info guys
