one tiny turbo, another decent sized.
u'd be silly not to go water cooled with the immence supply of water

just keen to see how they do the coolers/piping.
a lot of them run a cooler/plenum combo ontop, a few ran PWR barrel coolers.
Ok found out yesterday they are running two large water cooled intercoolers.
They are sitting in the side of the boat in baths that get pumped with water.
They are under these black covers you see on the bottom:

Also, simon was trying to explain the dual stage turbo setup. Its crazy and confusing. He said he has only seen it setup like this once before, and that was on a GTR skyline he built. The little turbos are working whilst also pumping the large ones ready until a certain time, then the large ones start working or some shit. (im not very technical when it comes to turbos ahah).The piping is amazing with so many cut off valves and stuff in the pipes which act like wastegates etc.
The large turbos have HUGE housings on them. They will be running 20psi each.
The plenums you see are custom made, he also has full carbon fibre ones made up too. The intake manifold is also hand made, along with all the pipe work you see. Also the block and heads are also items he cast from original factory spec items with changes he needed. The photos dont do this thing justice.
If your after a massive lesson in high-tech turbo stuff we should organise an hour to drop in and see him and check the boat out! My brain was melting from trying to take it all in.
