27. While Trask Performance sets its Turbo kits up with 8-pounds of boost, Nick informed us that the kit is capable of producing up to 20-pounds of boost which would make about 200hp and would require running high octane fuel. Increasing or decreasing boost can be done by loosening this locknut (blue arrow) and adjusting the rod (yellow arrow) to put more or less pressure on the spring inside the canister (red arrow). More pressure on the spring equals more boost. Another option to adjusting the boost is by purchasing a boost controller which would allow you to simply turn a dial to increase or decrease boost. Setting the kit up to produce 20-pounds of boost requires extra precautions to be made on the engine’s internal components to help withstand the significant increase in power. And while Anaheim-Fullerton H-D did make some internal upgrades to Ron’s engine, they chose to keep the boost on the mild side at about 8.5-9 pounds for the time being.
