The SUPERCAR NEDHEADS BN3 SUPERCHARGER SERIES equipped engine with Phase 2 - LS9 engine system produces 640 RWHP on this Mustang Chassis Dyno test, which is accurately estimated to be over 800 HP at the engine.

This level of LS9 engine power and performance is developed with the stock LS9 supercharger pulley, the stock air intake system and the stock air filter. Proving that total power production is simply developed with Supercar NEDHEAD BN3 Supercharger series Cylinder heads, custom LS9 Phase 2 Ned Cam, ATI Overdrive Harmonic balancer and 1 7/8 Primary Tube Headers and Corsa Exhaust System.

The superior performance capability of the SUPERCAR NEDHEAD BN3 Supercharger System is demonstrated by the boost pressure measurement on the Mustang dynamometer which shows a drop in boost pressure from 12 PSI to 9 PSI at maximum power of 640 RWHP.

The reduction in boost pressure is a result of the efficient intake airflow through the BN3 intake port & the increased exhaust flow through the BN3 exhaust port, along with the valve timing events from the custom camshaft developed by Ned, specially designed to work with the BN3 NEDHEADS to make big power with only 9 PSI boost.

Comparative Analysis of BN3 NEDHEAD Intake Port Flow

BN3 Cylinder heads flow over 380 CFM through the intake port, which is 80 CFM more flow than the production LS9 cylinder heads equipped on the ZR1 Corvette.

Technically, increasing intake airflow by 1 CFM can increase engine power by .25 horsepower per cylinder, which represents a 2 horsepower increase in an 8-cylinder engine. Improving intake airflow by 80 CFM can increase engine power by 160 HP (80 CFM x 8 cylinders’ x .25 = 160HP).

To achieve this power potential, the engine must have good, unrestricted airflow through the complete air intake system. The engine also requires the right camshaft profile and compression ratio to maximize the power potential of the intake airflow.

NEDHEAD BN3 Systems are developed as complete engine systems with custom designed camshaft profiles that optimize engine performance

Comparative Analysis of BN3 NEDHEAD Exhaust Port Flow

BN3 Cylinder heads flow over 270 CFM through the exhaust port, which is 40 CFM more exhaust flow than the production LS9 cylinder heads.

Technically, exhaust port flow should be at least 70% of intake port airflow to optimize the engines intake to exhaust flow ratio, to compensate for forced inducted engines boost pressure.

To optimize the efficiency of engine exhaust flow, the complete exhaust system must be unrestricted with the best exhaust system for the power level desired. The engine also requires the right camshaft profile with the best exhaust valve lift and duration to work as a complete and balanced engine system.

NEDHEAD BN3 Systems are developed with the best custom camshaft profiles, exhaust headers and exhaust systems with high flow catalytic converters.
