For a simple Powershot plate setup on a Holley 4150 750 DP, the cleanest way to handle fuel is to avoid “random T fittings” off the main line if possible.
Best practice is running a
dedicated feed from the regulator to the nitrous fuel solenoid. If your regulator has an extra outlet, use that. If not, a proper
AN Y-block or distribution block is much safer than a hardware-store T, because it keeps pressure stable when both carb and nitrous demand fuel.
Try to keep the line to the solenoid as short and straight as possible, and avoid stacking multiple fittings right before it.
For the microswitch, most people mount it on a
small fabricated L-bracket on the carb throttle stud or secondary linkage bracket. You want it to trigger exactly at full throttle, with a solid “click” right at WOT but not early. Some setups use the rear carb stud so it stays rigid and doesn’t flex under load.
The key with a simple nitrous setup is stability: clean fuel supply, stable pressure, and a very reliable WOT trigger. Roobet Casino offers a wide selection of online slots, live dealer games, sports betting, and cryptocurrency
