Was that full boost? 100% Duty cycle on the EBC?

No, after 58% at 4500, 70% at 5000, and 85% to redline. After a certain PSI you're stressing the engine and putting a huge amount of stress on the turbo for little gain. That's probably around 12psi for this turbo, but we went to 14 with an occasional spike to 16, and despite our efforts, power wasn't coming up above ~5500rpm, so we weren't going to murder the setup to try and get a more linear dyno plot.

My 1.6 had a similar plot on some shitty 2.5" exhaust, I really think 3" would help him here, but so would a bigger turbo.

Turbo and hot side parts yes, but also intake manifold

Here is someone who claims 254: turbo questions [Archive] - MX-5 Miata Forum

No proof or anything though. Just thought I'd share.

I have no desire to change anything unless turbo or manifold wise, wastegate dump and 3 inch will happen as well as perhaps a Honda I'M at some point. I like the msm manifold, turbo and lines a lot, no need to change it imho

Curly,

Where is the EBC being referenced from?

Look at his funky intercooler setup, it's ~8" from the throttle body.

pictures are blocked at work or I would

I ask because I'm about to install my diy ebc and don't have a port/nipple pre-tb, and was thinking of referencing off the IM and wondering if a 1way check valve would prevent vacuum to the wg can or just run it that way without the valve since pre boost the ebc is at 100% which should be closed.

thoughts?

Off the IM?



With a 1 way valve wouldn't you just be pressuring the wg line with w/e psi you're running...

In turn, lose boost once you shift gears cause the wg is already open with said trapped pressure?

the ebc has 3 ports and the 3rd vents to atmo but I see where you're going with that, might not be a good idea

Huge no-no. boost will build behind the throttle plate with small amounts of throttle, that'll let it spool to the heavens.

Do you mean the supply of boost going to the EBC, and then to the WGA? If you are using Megasquirt for boost control, then isn't the reference IM by definition, and hence the convention of setting up boost and throttle position?

Honest question.

that's what I was getting at: you CAN make the ebc work referenced from the IM, but it sounds like more work with settings and valves possibly than it's worth, and I really don't want to put any vacuum through the wg can of this 72k mile turbo

sorry for off topic, I can make separate thread if this gets cluttered

Honest question.
Boost that Megasquirt sees comes from the IM. This tells the EBC solenoid to open and close. The EBC solenoid is connected from a pre-throttle body boost source (either at the compressor or right before the throttle body) then to EBC then to wastegate.

Correct, he's referring to the ebc plumbed source, not the electrical source from the MS, which is from the manifold.

MS=post tb
EBC/MBC=pre tb

I'll make this a new thread when I'm in front of a computer.

You're probably going to laugh at this, but do you guys have a drag strip in your area?
