sporadic's Turbo Duratec build #2

[SaleenT121]

The spool time could be up because the GT is a ball bearing turbo vs that journal bearing.

I'm heavily considering mounting my boost controller in the car, in a console I've literally never used.
The distance of hose to it would be somewhere around 4-6 feet. Is this too far? I know my boost gauge line is further than that and it certainly seems instantaneous in its readings.
It would be far more convenient to be able to adjust the knobs in the car.
Thoughts?

This build makes me want a turbo focus.

Go for it.


I went ahead and mounted the boost controller. I'm still waiting on the silicone hose so nothing is hooked up yet.


While looking for a good place to drill a hole in the firewall for the vacuum line I found a small miracle: a factory-plugged hole right where I wanted one!
It's behind the glove box near where the A/C lines come through. I twisted a screw through to see where it popped out.


See screw in the center of the photo:


I also wrapped the turbo to help the underhood temp. I'll wrap the downpipe later. I hate to because I love the gloss black.

Wow, looks good man. I seen laser heat reading with no blanket, and with blanket on the turbo, and it really helps.

Now THIS is more like it! Boost controller is now hooked up. I'm only running the stage 1 of the 2-stage boost controller until I drop in a built motor. Basically I didn't bother wiring up the switch yet that opens the second bleed-off valve.
I installed a 6-port vacuum block even though I only hooked up the boost controller tonight. I wanted to make sure I had enough 4mm silicone hose to route the boost controller before re-routing the BOV and boost gauge. Eventually the BOV, meth injection, boost gauge and boost controller will be routed off the same vac block.
The boost is now set around 9psi (vs. 6-ish psi previously). Just moving the boost source from the compressor housing to the vac block bumped it to ~8psi. A couple clockwise clicks of the boost controller set it to 9psi.
Tomorrow I'll do some datalogging to dial in the AF and timing more carefully. AF looked good tonight but I also didn't really run it hard. I just wanted to check peak boost.

Vac block (bought from Amazon)


Boost controller T. This contains a spring and ball to decrease spool time, but it also causes a momentary 1psi boost spike. So far I consider it a fair tradeoff.

Well i think Ive just found my new favorite thread. Wish i had the time and money to finally get my kit set up

My opinion is you should never hook the WG PSI Ref from the turbo always from the intake manifold ,

9 feels much better doesnt it LOL

Yes! I can't wait to get out and do some runs and data log later today.

I turned the boost up to 10-11psi and tuned it tonight then turned the boost down one click. This type of boost controller doesn't hold rock steady; it slowly floats +/- .5psi at peak boost. I knew that might be the case when I went with the bleed-off type boost controller. It doesn't particularly seem to be a problem. This might be the result of the ball/spring setup in the "T".
MAF counts are peaking out around 900 at 6500 RPM at 10psi. That's 20 counts up vs. the 12psi of the IHI turbo. It's safe to say this flows a higher CFM.
