My 66' Turbo @ the Dyno

[Amurray]

Well I finally found someone that is competent on tuning my car with my Electromotive Tec-GT ECU. It didn't go exactly as planned but I am please non the less. The results have me VERY excited. The temperature outside was around 92 degrees (to dang hot). But here's the jist of it.

With the 10lbs spring only EBC off the car made 195hp 195ft lbs torque.
With the ECB on it made 250hp 250ft lbs torque.

We tried to push the car to 20psi but the EBC kept opening the WG @ 18.9psi @5200 rpm but the redline is 7500rpm. On those pulls the car made 300hp 300ft lbs torque. What we noticed in all the pulls is the torque trailed the HP and never dropped off
We actually want to push the car to 27psi All the way to redline but the eBoost 2 would not allow that to happen. WTF

It wasn't all bad because I found out some great results. During all the Dyno run of the day the temps coming out of the intercooler never got above 124 degrees, oil never got above 160 and the heads never got above 200 degrees (CE heads). This engine LOVES water/meth injection.
I couldn't believe what I was seeing

Last night around 11:15pm EST I sent an email to TurboSmart to explained the issue with the EBC. I received a call in 10 minutes of that email. Well the rep walking me through the steps of how to program the EBC in real time (talk about customer service). We found out the EBC has an issue. They are having me to send it in for repair. If they can't fix it they are sending me a new unit and everything is free of charge .

As soon as I get the EBC back I'm going back to the Dyno to finish what we've started. So like I said it wasn't all bad.

Very nice results!

Good results!

You won’t make more than double the WG spring with a EBC (unless you run CO2 also).

Bump the WG to 15psi

Why is that???

I have a 6.0 lb spring in the WRX turbo I run and I have gotten 26.5 lbs with the EBC.

Very nice! She's gonna be a handfull!

The boost controller can give 100% of the boost added to it, to the WG. Then you will double the spring tension.

It can’t give more than 100%.

Rest is boost creep, WG placed wrong, woo small WG etc.

I wonder if we have them connected incorrectly? I had no problem boosting just over 30psi. Maybe I'm bleeding pressure to the opening port?

[buguy]

I just wanted to edit this. I used to be able to make 30 psi on my 12# spring with the ebc. Seems now like 66 said, all i can do with the new engine is double the spring pressure.

Unless you use a 4-port EBC

Does it? How does it create more pressure on top of the spring than boost pressure? I was under the impression that it just was a more precise instrument

It also keeps/regulates (counter)pressure under the spring, so at any boost you have always the (wastegate)spring pressure as overpressure.
At least as long as you have less overboost in the exhaust with regard to the wastegate springpressure. In other words: only if you have a really bad exhaustpressure/boost ratio, you're f*ck*d, otherwise it should regulate whatever boost you want with whatever wastegate spring.

So better control of your boost pressure.

I still can’t understand how it will let you boost over twice the WG spring. It can’t give more than 100% of the boost from the turbo..?

If your WG is placed good, a 1 bar spring should open at 2 bar, with a 3 port. But can a 4 port give more than 2 bar with a 1 bar spring?

Ok. Article has been read and a 4 port ordered. It will be here tomorrow and installed by the weekend ready to report back the carnage!
