Does anybody know how much boost the R18A1 engine can take without hurting the life span? im thinking about 7 to 8 psi but im not really sure where to set it for top performance but keeping the stress on my engine to almost nothing

 

Whenever you add FI to an engine, it will be more stressful to the engine because you are cramming more air in there. But yeah to stay at low boost would be best
