Dans Turbo Build

[dan944]

Dan when are you booked in to RRR?

I'm not yet. I've been waiting for the answer on them cracking the code lol

If there is this interim solution that is proposed then I shall be booking ASAP as I'm on two weeks leave at the moment.

Also I'm dying to get this thing on the road and now it's not me that's holding things up. Lol.

I've not been on here much recently but the kit you are building is very similar to the one that I built and have running on my car.

I used the GT2554r turbo too replacing the wastegate actuator with a 0.5bar (7psi) version, and it does make the car very lively!

I'm in New forest area so hopefully I'll see you at one of the meets.

This is how mine did on the Dyno

No way!! You're just down the road then.
From what I gathered the standard actuator that comes with it is 7psi?
What does it actually come at?

Is that 170 bhp or whp? I was hoping for a little more than that really so will try to run rad higher boost if that's the case.

[1979scotte]

Must be whp
Even the TTE turbo makes more than that. On paper at least.

[dan944]

Hope so 

Just did another google and apparently the actuator pressure is 10 psi. Should be good for the magic 200

[monsi]

Yes quite a coincidence! You'll have to let me know if you want to come and have a look.

I think the turbo only comes with a 1 bar actuator which is too high for a standard 1zz. I brought a 0.5bar one although I'm not sure of the part number and made up a mounting bracket.

The Dyno figure is whp and was finally a bit higher that as I was originally using the standard clutch that slipped as soon as the torque came in.

The car does feel very lively with this much power and it spools nice and quickly. My next move would be to setup the boost control which would further improve the spool and power!

This is going to make 200 whp or 230 at the fly easy.
You've got a full standalone ECU big injectors etc etc.
Unless your intake temps are massive this is going to be a little rocket ship.

Also not going to tell the Tuner his job but the SP240 turbo hit 10psi in the mid range but tapered off to 7 at redline supposedly for engine longevity I believe.

It's a bigger intercooler than the TTE/SP240 so intake temps should be quite decent on Dan's setup. Location of the intercooler isn't as good though so it might end up being 6 and 2*3

Charge cooler would be better but it should be fine for this sort of power.
Probably loose a few horses on a hot day.

Ooh I'm all excited again now.  I like the sounds of rocket ship. Does anyone know how you post pictures by the way? Didn't there used to be a thread on this?

How would I go about finding the rating of the actuator?  Check for a part number? If it's 10 then I'll leave it but like you said if it's 1bar then I'll have to get something new :/.

I'm hoping I can get decent air flow to the IC where she is but may have to make a scoop of sorts.

[monsi]

From what Scottie was saying you might be better off going for the 7psi actuator anyway then use boost control to increase it. I'm sure that's how the SP240 worked to reduce the stress on the engine.

Out of my depths again    lol

What do I need to get and how does it work lol.

Either upload using the attachment option or use something like imgur

Yup. Tis the easiest/safest way

[dan944]

Here's how the IC Sits.

[monsi]

The theory is quite straightforward, but the ECU needs to have the feature. The vac hose from the inlet goes through a solenoid controlled by the ECU to the waste gate actuator, the ECU can then open or close the solenoid allowing pressure through to the wastegate.
So if you have a 7psi wastegate but the ECU is commanding 10 psi it opens the solenoid so the wastegate doesn't see the extra boost until it's almost there then closes the solenoid the wastegate immediately opens limiting the boost to 10psi, this happens over and over again very quickly. As a bonus because the wastegate doesn't see the boost slowly building it doesn't begin opening too soon improving the spool.

Love it. It's engineering genius.

Any recommendations on a boost controller?

Also need to check my actuator tomorrow :s

Black has boost control built in And very good one at that

[monsi]

I'd check and see if the standalone ECU you're getting will do it. If not It's is possible to use a spare pwm output but thats a bit less sophisticated.

Otherwise there are dedicated boost controllers on the market, have a search and see what the SP240 used.

All sorted then! Just need a solenoid :-)

I really need to read up more on this ecu.
Honestly, if it had a flux capacitor I wouldn't be surprised.

So any electronic boost solenoid recommendations?

Yes. The MAC one recommended by ecumaster and sold by RRR hahsa

[dan944]

Touché lol

[dan944]

Just bought the same solenoid for £20 less and checked the actuator and it's the 7 psi one as standard. Very pleased

Win!
I'm assuming we can keep our existing one as well.

So close eh?

[1979scotte]

It is a fully featured ECU as good as anything out there under 2k.
Of course it does boost control even the DET3 PIGGYBACK does it.
7 psi spring on the wastegate is perfect.
Engine won't go kaboom if the failsafes umm fail.
Happy Boosting.
