Hi Bill. Was hoping to get your opinion on mating a k03 turbine housing and wheel to a k04-023 compressor housing and wheel in terms of what sort of a power band and peak power figure would be attainable and the susceptibility to surge. I realise that EGT are going to be an issue.There is very little to no constructive and conclusive information on this subject. I known that this isn't pertaining to your business or products and appreciate you taking the time to read it and hopefully answer. Thanks, Samuel.
