EcoBoost - E30 Tune + Intercooler potential?

[metroplex]

I was reading a write-up from Speed Factory where they talked about dyno'd gains from stock all the way to their custom tune and their Intercooler. They got it up to about 400 hp at the crank.

I'm curious to hear from actual EcoBoost owners/tuners and to see what the potential is with the stock turbos and running E30 w/ the aftermarket intercooler? I'm sure you could push the timing to like 23-25 degrees, max out the boost based on the compressor map with the E30. But what kind of timeslips are you seeing?

Reading through the forums, 400HP , at the crank even, might not be sustainable without upgrading the turbo, fuel pump, and DP. You might hit it once or twice under optimal conditions on a dyno, but real world wont be reliable.

Depends on what e30 mix you're running. 106 probably on 91 mix and 108 on 93 mix would probably be the most MPH (in the 1/4) I'd want to see. Anything past that is getting dangerous on a stock turbo.

How much boost can the stock turbo handle / max airflow before it hits the choke line?

You can crank up the boost all you want, but it won't hold it. You are also heating up the air quick with the small turbines that are liable to burn up.

Let me rephrase, what does the compressor map look like? With my EcoBoost SHO, I found out by accident that there is a point where it just will not allow for more boost. But that is way beyond the choke line. And yes, there's a lot of heat produced hence the need for an aftermarket intercooler. I looked at the speedfactory dyno charts and the aftermarket intercooler allowed for a dramatic reduction in IAT2/MCT.

On my GM LNF, I'm pushing 24 psi through the K04 (2.0L I4) and the stock intercooler does a tremendous job cooling it down (bigger/better design, proper placement). On my SHO EcoBoost, the stock intercooler is terrible and has trouble rejecting heat with anything more than a few psi over stock (poor location and less effective design).

I trap 107-109 on straight 93.

Key word "safely"


alot more factors into it. But that kind of MPH I rather have more octane than less. All the guys going fast have said the key to these motors staying together is over octaning them.

 

[Slow89]

I'm short I would definitely not feel comfortable with that much MPH on full weight car with only 93 octane regardless of the track conditions (D/A)

400 at the crank is like 330 at the wheels. Which is definitely well within the possibilites of the stock turbo and e30. Mixing Ethanol with good fuel is necessary though.

23-25 degrees timing is way too much. On e30 you're limited to anywhere between 9 and 12 degrees BTDC at redline depending on your set-up and fuel quality. Biggest limitation is the knock threshold and stock turbo. A fully bolted car, e30 fuel, and a good tune... 350-360whp (400-410hp at the crank) in good weather. The stock turbo is good for about 27psi discharge pressure (choke line)(this is before going through the hot side charge pipe, intercooler, cold side hose, throttle body, etc.) depending on how free flowing your set up is you could see as much as 25psi at the intake manifold at low rpm and will taper down to 21-22psi at/near redline. You can upgrade the WGA and gain some WGDC back and try to hold another 1-3 psi up top, however knock will be the biggest limit in this zone. Really most gains to be had on the stock turbo is in the midrange, the powerband can be extended with tuning, but you reach the point of diminishing returns and literally start playing with fire trying to push the stock turbo and stock block up top.

Here's some video of an E30 Tune+ car doing work at the local 1/8th mile. This car has a stock intake w/drop in filter, Tune+ IWG, Megan Racing Catless Downpipe, MAP Street Core Intercooler, Cobb Accessport Pro Tuned by www.adamtuned.com with E30, running on Denso ITV22s, and a UPR Catch Can. Has run 7.9X's in the 1/8th mile on this setup:

And then here's some video of my personal car, with the same setup as above basically:

(*I'm no longer on E30, now running full aux fuel setup for full E85.)

i dynod at 320hp 399 torque with e30 and mishimoto intercooler only.. adam wasnt to happy with the results. I will say it was very humid that day and the charge temps were at around 110 on a 78 degree day.

 

[stevnoof]

on a manual car you will run around 12.8-13.0 107-110mph with good 1.8 60ft. your tune will probably run around 24-25psi 10-11 degrees max timing.

I have been reading all the talk about mixing gas. I would love to use 93, but we only have about 2 stations within 25 miles that carries it. Two stations have 93 that is already 30% ethanol. Would this be safe to use as I'm currently on stock tune?
