My guess would be "Yes", Bob...
With ALCOHOL/water injection. Stock
HC 1275's run only 8.8-1 and the Turbo
Metros ran higher. They also had forged
pistons but the stock Spridget piston
while cast, is a pretty strong item as they
take low pressure supercharging (with
appropriate 100RON gasoline) without
a problem. This would be up to 7psi.
Intercooling makes a big difference but
alcohol/water really "brings back" the
leaded 100+RON octanes of yesterday.
This stuff injected in appropriate amounts
really cools down the combustion process.
The Turbo Metro head uses the larger
1.4 intake valves I think. For more info
I would talk to "Daniel 1312". He knows
more about these than I do for sure and
Dave Vizard talks about these in his
fine book on tuning A Series engines
as well. Worth a read.
