what do you think?

what would be wrong with having a greater (water cooled) space between the exhaust and compressor sides of a turbo assembly?

 

More information......>>

Zed turbos are already watercooled, what are you suggesting?

 

creating more distance

between the exhaust and compressor sides, i am suggesting that a greater space would reduce heat transfer between the turbines. cooler inlet air.

 

HPC coatings would probably acheive the same ...>>

and be a lot easier to do.

Where are you going to find the extar space under a zed bonnet?

 

I'd doubt you'd find a CHRA with a longer shaft that'll fit the

correct compressor and exhaust wheel trim.

 

HPC Extreme does the job nicely.

 

fair enough, that will be tops when finished. chewy.

 

would fitting a fin type of arrangement make a good heat sink?

 

the idea is to get the heat out of the turbos and down the exhaust

so that the temp of exhaust gases stays the same as much as possible till it exits the mufflers to ensure maximum extraction of exhaust gases (a gas cooling down in the exhaust will slow the gas flow down). A heat sink would only be of use if it had some decent airflow over it and the position of the turbos don't lend itself to heat sinks. Without working it out you would need a heat sink the size of the car to make any cooling difference on a turbo considering the temp of turbos run up to 1000 deg.

 

yer i couldn't see there being much you could do

about the exhaust side, what about a independent water cooled suck and blow sides of the compressor?
