Hi all,
Engine- Flat four, air cooled, was 1588cc - soon to be 1883cc, head/valve work, twin plug ignition, split-lobe cam, etc.
Service- Dedicated, lightweight autocross car.
Hoping to achieve 35-40% power increase but mostly a higher and wider torque band. I have been advised to cryo treat the crank and rods. My questions are about the order in which this should be done. Should shot peening be employed and if so, where in the sequence? Is this the correct order? -
1. Crank magneflux & inspect
2. Grind (if necessary)
3. Remove/clean/replace passageway plugs
4. Balance
5. Cryo treat
1. Rod inspect/straighten
2. Rebush small end
3. Balance
4. Cryo treat
Any other components that will benefit from the cryogenic treatment?
