Btw, the guy that built the exhaust for that boat lives in my neighborhood and does welding and fabrication still.

Here are some pics of the exhaust mods we've done you can see the first most noticed is the replacement Garret water cooled ball bearing turbo then the modification to the exhaust with the Tyal adjustable waste gate operated by an Innovative boost controller on the dash that controls both engines at the same time and the addition of the merge type collector flange which we use in the drag race engines I'm confident in the exhaust system alone we have another 100 hp to safely use. Hope you guys enjoy.

i do little 2.2l audi turbo motors and at 500hp to the ground,,our exhaust systems glowwwwwww
very pretty at nite.
garrett makes the water jacketed exhaust turbo housing but they want some bucks for it,,

Re: Mesa Racing Engines Latest Project
The water cooled turbine housings are incredibly heavy..... you can't hang those out there on the pipe setups he has showing... they'll crack, and break the flanges right off.... those turbo's are nice pieces, wrap the exhaust and run it...
My only concern would be turbine tip speed, at 8500 rpm engine speed, for loooong distances, your talking over 225,000 rpm on a T5 or T6 frame turbine wheel diameter. The trick is the tubing size, and a/r ratio's matching up...
I wanted to do this setup last year for my Criterion, using a 366" truck block (I have an NOS 366" tall block on the shelf now) .125 over, 3.766 crank, alum. heads, EFI, Hogan intake, maybe 385"-395", single BB turbo, intercooled.... my wallet dried up. I think a 447" may be a better way to go now... JMHO.
