Just wondering really, what is the safest maximum hp a k03s turbo can safely operate and use please? It's not a case of how much it can handle, it is how much it will produce The question should be what is the maximum pressure and air flow the K03S can sustain. At a certain point the diameter of the compressor inlets and outlets limit the amount of gasses that can flow through.
I wouldn't push a K03S past early 20's psi about 1. If it's remapped stage 1 it usually peaks at about 18 or 19psi 1. Are you sure your gauge is in psi and not bar? Does it read vacuum negative figures as well as boost positive? What no pics of something to accompany your post? You've been quiet recently Rob running out of ideas for things? Its how much boost it can handle, not the power it can produce.
Its all about the hardware and mapping of your setup. Like mine i only got bhp as my cat is stock!
DIY: Adjusting the Turbo Wastegate / Preload for More / Less Boost
But i dont have for a milltek cat and zorst and a decat is a no no. I wouldn't invest in any more horses for my VRS, without first investing in some serious handling upgrades. I love my VRS as it is now; with the stock map, and the horded it felt a little 'under potential' but mapped, it's a phenomenal all round car. You need to be a member in order to leave a comment.

Thread starter ThunderBunny20 Start date Apr 14, ThunderBunny20 Seasoned Vet. I dropped my car off at the dealership and asked them to look at a n airbag fault message for me and when I scanned the car I also recieved a low boost code and a code for the intake manifold runner stuck open. The servie person I spoke with said that they have had someone who had an aftermarket cold air DV exhaust and tuning that blew up there turbo.
Is this possible to have too much boost with the KO3 and have this happen or is this just one time only? He had said that the shrapnel form the blown up turbo cut into the block and messed up the pistons and went into the intercooler as well so the whole engine needed to be replaced.
Also he had called me back about a low fuel pressure reading and that I am actually running low on boost so that will be more issues I have to deal with. Location A Garage in Maryland. Good Luck with that adventure. So you've either been running the car low on oil, consistently, however that would be indicated by excessive cam follower wear and or you just got a weak oem unit.
Granted, I don't expect mine to last forever with the punishment it see's either, but not to the point I start ingesting shrapnel! Good Luck. ThunderBunny20 said:.

Most turbos in India I guess. The best part is that, you can increase or decrease the boost, and hence increase or decrease the power of your turbocharged vehicle at home, with just a spanner and a plier.
What all you can do: Increase the max boost at higher rpms. Decrease the max boost. Zero Boost. Bypass the turbocharger.
Maximum possible boost. Given below is an illustration of how you can adjust the preload setting of your turbocharger.
Mine is a 2. Usually in a Turbo: And, Usually what happens in a turbocharger is: The boost is built up in the compressor, and the black pipe, which can be called the boost sensor? More boost, more pushing down the rod. Pushing down the rod means opening the wastegate valve.
Opening the waste gate valve creates a bypass way for the exhaust gases to escape, without doing work on the turbine wheel. Hence, the compressor fins doesnt turn, and boost drops. When boost drops, the rod is pushed up by the spring which again closes the wastegate valve, and hence now, exhaust gases have to escape by doing work on the turbine wheel, which inturn builds up the boost.
Hence, by this wastegate mechanism one can decide on what max boost one can run. Now, the adjustment: Remove the pin or circlip which holds the rod to the valve.
Loosen the nut shown in the figure below. Now, y ou can turn the rod to increase and decrease its length. What all you can do: Decrease the maximum boost: By increasing the length of the rod, you can reduce the preload which means, lesser boost is required to open the wastegate valve.
And hence, lesser maximum boost.Forums New posts Search forums. Media New media New comments Search media. Resources Latest reviews Search resources. Members Current visitors New profile posts Search profile posts.
Having a fixed vane wastegate turbo and being able to drive the car like a diesel low rpm and using the torque and not have to worry about the vanes jamming is right up my alley. Frankencar Veteran Member.
Well since my turbo is just about blown, I need to make up my mind It's hard to say tho since the car is kind of my toy since it's in my cabrio but soon it will have to be my daily, I just want a little more power than I have now without all the work to get it running again.
I like the bolt on part of the hybrid which is prolly what I will go with unless I need to save the money and go with the stock for a little over Admittedly, I mechanically adjusted boost from 17 to 21 psi. But one can argue that the hybrid is more robust and better suited for handling 21 psi than the stock turbo.
VNT Swap The conversions I've seen were "works in progress. I wouldn't recommend one as a performance upgrade only. But I certainly consider it a good move for anyone in need of a replacement bolt-on WG turbo. Stealth TDI said:. Last edited: Sep 4, JFettig Vendor.
