Yeah,I've thought about that too !!!!:D:D
I don't think that forced induction is a very good choice for any car like ours with 9.5:1 compression.
New cars with fast-burn combustion chambers, computerized fuel injection, direct injection, knock sensors, flex-fuel systems (e-85) and digital spark systems that are factory-tailored for that particular engine's state of tune can get away with it... I don't think that most slant six setups can.
You might be able to run some supercharger or turbo system that gives you 6 or 7 pounds of boost without incident, but you can get that kind of power easily, normally-aspirated.
Idealy, I think about 8.5:1 is optimum for running significant amounts of boost with this engine. And utilizing all the octane-crutches available to we slant-6 racers have at our disposal (intercoolers, ancillary alcohol injection, spark retard, race gas, and a well-tuned fuel system,) we are probably pushing it with our 9:1 combo.
We don't have an O-ringed block, and if we get by with 20 pounds of boost without blowing a head gasket, I will be very happy and very surprised!:blob:
Just my 2-cents...
