Very clean.
TR30R? Pretty exotic, usually reserved for endurance racers (ex: Audi R8) and pro rally.

yes, exotic, but very effective, very very little LAG,

I think a2w is ideal packaging for a rear or mid engine high hp turbocharged car. Horizontal and top mounted ics just can't have the same mass flow rate as a front mounted heat exchanger. That said I wouldent really want to cut up my original 930 to install one.

Agreed, but where to place a sufficiently large radiator with good airflow on a stock-bodied 930? Put it in the wing like the stock A/C condenser, or mounted over the engine in place of the stock intercooler?
Thanks! MODE does make some pretty amazing stuff.

Pat Wiliams is the guy who deserves the credit on the engineering.
Because of the extended DP tail we had no problem mounting two Setrab radiators. Perfect for air flow to cool the water. I did do it just for something unique, but we were amazed how the Outlet temps barely budge on repeated high boost runs.

A friend of mine is building a "934" spec EFI engine with watercooled IC-plenums. Hopefully it will be cool enough for ~750hp

Love seeing that car above when it pops up time to time. Engine looks awesome, the air only travels a short path through the A/W intercoolers.

I'd prefer the air to air intercooler because I think an air to water one would add a little more weight to the car. You can fit an air to air intercooler under a ducktail by using the OEM intercooler, removing the seal around it, and trimming the edges a bit, or by mounting the intercooler at a transverse (side to side) angle. I've seen both methods done before, so it's definitely possible.

Wonder if one of these would shoehorn under the rear deck lid? Might have to be modded a bit.

LMAO! Now that's some serious anti-heat-sink equipment. Hmmm now if I can just reverse engineer it...

It was done just because air always finds it's way to intercooler, but more important is to create a low pressure area behind the intercooler and that creates air movement.

Eddie Bello got his working.



And a dyno comparison vs. his air to air.
