a little update. the motor is still on the dyno
. at the first run we found a bad head gasket that is water leaking to three cylinders and forced us to take the motor to pieces again.
the new SV-1 carb failed at the next dyno run. The motor stumbled under load and was flooded with E-85. After a couple of hours of discussing the prob - we have tried a 700cfm 4-barrel carb. Concerning the much too small carb we only rev it up to 5000rpm and made 728HP
I'm very exited what the engine will do with a carb that really fits. The SV-1 is back at the producer for an overall check.
