You know that the boost pressure is fed directly from the turbo output to the actuator? I assume you know this but here goes: The pressure starts to rise which is immediately fed to the actuator, which STARTS to open the wastegate. The more the pressure rises, the MORE the actuator opens up the wastegate. What you'll get, is the turbo lag (waiting for spinning components to speed up) slowing things down, as well as the wastegate progressively opening. this will give you a pretty slow rise to the maximum boost level. Also, you're raising the max boost pressure achievable by bleeding a bit of air pressure out to defeat spring pressure. Have you thought about fitting a boost solenoid on the pipe between the intake and the actuator? With this, you'd get absolutely NO delay in the rise of boost, other than the physical turbo lag. There would be a sensor in the intake pipe reading the boost pressure, and this reading would be fed to some kind of controller. The controller would hold the solenoid closed until a pre-set boost pressure was reached, at which point the controller would then start to switch power to the solenoid on and off really quickly. This would mean that the solenoid would never really be fully open or fully closed. The whole system would be closed loop, where if the boost pressure dropped even a little, the solenoid would be allowed to close more fully and so it goes around and around. The above would vanish the delay AND give you total control over the max boost pressure. You could even have a bank of microswitches at the gearstick so that in 1st gear, the boost pressure would be kept fairly low, with 2nd gear slightly higher and so on. It would be trivial to have a dash switch for "Snow / Valet" that eliminates boost back to spring pressure, "Road" for good useable power & "Track" for best effort runs. Fuck knows how much a new controller like this would cost from Greddy etc, and I hate Chinese shit electronics with a passion. I don't have a turbo car at the minute (cries) but I can solder and code like pornstars fuck - Is a solenoid project something you'd be interested in trying? I could lash something together in a couple of weeks if you're game. Give me a shout if you're interested.
That sounds super interesting and would be a great thing to add to the car as there is a lot of lag as you say then it just hits max boost which is what i set using the bleed valve, a solenoid would definitely be something I’m interested in!
@@houseofmods I never followed through either :( I ended up moving for work and since then my life has been in boxes as I never really unpacked. It's certainly still doable though.
Its already mapped at about 160bhp ish , would I still need a front mount intercooler with this turbo and my passat as only just passed 1oo thousand miles. And thank you
Hello, a turbocharged car has about 20-40% more total power than a non-turbo car of the same year, make and model. Turbocharger GGT2871 can boost your car's engine up to 350HP. Its special K418 alloy Turbine Wheel can withstand exhaust temperature Above 900° and ductile iron QT450-10 Turbine housing Can withstand temperatures up to 700℃. Overall, this is a well recommended universal turbo.
Hey man it was kinda hard to read, really fast. What was the max horse power, and how's it doing so far? I'm about to bolt one of these on a 1.4 ecotec.
i recommend apexi avcr, but they are still pricey 2nd hand.

@@houseofmods I'll send you an email.
Did you ever end up getting this concept working? I find the idea really interesting.
I never followed through with it, would be interesting for future projects though

I have a 2010 passat tdi R line would this turbo make a big difference to my motor ? Can't wait for the bora build and thank you

Flat out in 4th gear it pulls to 4950rpm and im doing 110mph if this is any help and its my first car , always had vans lol
Hi david, if you email maxspeedingrods they can guide you through whether or not this turbo is applicable for your car! Thank you for watching!

never run the restrictor on journal bearings! you want to keep destroying them then by all means go for it.
Never destroyed more than one so i will go for it 😊
@@houseofmods thats just silly man, cant wait to see what my t04e is like, journal bearings need as much pessure as possible,
What litre is the engine ik sounds silly but im building a 1 litre micra turbo atm nd looking into turbos nd this is priced very well
This is 1.8 bud
you want a td04 or ko3 for the micra, i know this comment was 2 years ago
Great video.
Thanks broski

Hi mate i made 275hp and it is holding very well! Hope the 1.4 dont make the spool time really long as there quite a laggy turbo
how many boost you use for that hp?
1.2 bar
My g 😛😎
