He has a thread on patrol4x4. 5 videos so far.
I think anyone who goes non vnt these days has some rocks in head lol.
Boost earlier and longer.
But its a pretty sawesome build ey.
Not really. You are still restricted by sizing.Quote:

That is true with extranal by passed etc i guess standard turbos are a lot more involved than the use to be..Quote:

I dont think you quite understand compounding. Compound turbo setups have them the opposite to what you would think. The big turbo feeds the little turbo
The only job the little turbo really does is compress the volume from the large turbo.
Ideally you dont want any form of control weather it be a wastegate, vnt or vgt but control boost by fueling across the rpm range. While possible its hugely expensive hence why you will see things like cvt and 7+ speed transmissions become more popular as an engine will always work better with more performance at constant rpm. You only have to look at things like boat engines to see this.
Your spot on, i really have nfi with compounding lol..Quote:

They use waste gates etc to bypass and direct..
Fk fault finding on that
Caterpillar had twin turbos on their C15 accert engines & they were nothin but trouble & never went that well , I know of plenty of blokes that pulled em off & went to a single turbo manifold & shut off the unnecessary shit in the ecm . Over complicated setups I believe - a lot of things have to work together perfectly for it all to work & more things to go wrong but each to their own I guess .
Hahaha dry all right , all done with no shoes 😝 I like the bit where he stares into the camera & taps the snorkel 🤣Quote:
