nitrous setup help

The holley regulator is a dead head regulator. No return line. Actually the holley regulator is good for spray. run at least 3/8" line from tank (1/2" preferred), the pickup in the tank should be the same size as the line, a fuel pressure guage isn't a bad idea either. Then there's the purge valve, and the bottle heater, to do it right, plan on spending double what the system cost. Ignition, buy the best you can. you have to pull 2 degrees of timing out for every 50hp shot. 100hp is 4 degrees. My mallory ign is programmed to pull 6 degrees of timing out whenever I power up the nitrous system. That way you can't forget.
