Bruce Benson's input on my turbo question was extremely interesting. It would seem to me that, designed from scratch, a "blow-thru" system would be no more difficult than a "blow-by". From input received so far, the only disadvantage would be in the lack of vacuum to run auxillary devices. Vacuum cannisters are available for this purpose. BTW, Turbonetics has purchased the automotive turbo portion of Rajay's business. This could hold promise for those running Rajay turbos.
