Not quite Harv, 149 series engine was bigger. There was also an old 110 series with radial blower/s too.
The blowers didn't do much for HP gains unless they had stepped up blower drive ratios fitted. Most later turbocharged engines had blower bypass valves that operated when the boost come on song. The turbo's made all the oomf.
Pic below is a 8V92TA I built. She made 735hp and spun to 2300rpm, all from a 12 litre engine!
A very sweet noise indeed!
