Edelbrock E2 Direct Port

Nitrous Nozzle and Jet Map Information

Catalog # 72552

INSTALLATION INSTRUCTIONS

Edelbrock engineering has conducted extensive dyno testing with the Edelbrock / Glidden
E2 Direct Port Nozzle to provide jet maps and different jetting levels. The dyno testing
conducted at Edelbrock was done using Edelbrock Nitrous Components. The Edelbrock
E2 Direct Port Nozzles are compatible with most direct port nitrous systems on the
market.

The following is intended as a safe guideline for most direct port systems utilizing the
Edelbrock E2 Direct Port Nozzle with a

flowing

fuel pressure of 7½ to 8 PSI and a nitrous
bottle pressure of between 950-1000 PSI. Ignition timing generally is retarded 2° for
every 50 horsepower worth of nitrous.
