turbo: blow thru vs. draw thru

This is the main book you'll want to get and is a must have for an old school draw thru turbo set up. 1971 edition wrote by Huge MacInnes. That guy was the MASTER turbo guy of his day, and in fact turbos today are using HIS designs. Rajay turbos are almost indestructible and that's why the FAA certified them as the ONLY turbo for aircraft up till the 1980's. A single 40 year old Rajay with FAA certs still sells for $2000 used.
That's a 1970 Olds Cutlass 350 with a factory twin turbo from Oldsmobile using a 600 CFM Holley.
