Comparative Analysis of BN7 NEDHEAD Phase 4 System and stock LS7 engine demonstrates that the BN7 Phase 4 system increases LS7 engine power from 414 horsepower to 616 wheel horsepower on Mustang Chassis Dyno Tests.

BN7 NEDHEAD Phase 4 system increases LS7 engine power by 200 HP which represents 49% increase in maximum horsepower. The maximum horsepower range is extended by 1000 RPM from 6300 RPM for the stock LS7 engine to 7300 RPM for the BN7 NEDHEAD System.

200 HP more maximum power and extends power range by 1000 RPM.

The extraordinary power of the naturally aspirated SUPERCAR NEDHEAD BN7 SYSTEM is demonstrated in comparison to the Supercharged ZR1 Corvette on Mustang Chassis dynamometer tests. The Z06 Corvette equipped with the NEDHEAD BN7 Phase 4 System produces 100 horsepower more than the Supercharged LS9 engine in the ZR1.

The naturally aspirated LS7 engine in the Z06 Corvette, equipped with the BN7 NEDHEADS Phase 4 System, produces 22% more horsepower than the supercharged LS9 engine in the ZR1.

BN7 NEDHEAD System - more power than a supercharged engine.

Comparative Analysis of BN7 NEDHEAD Intake Port Flow

BN7 Cylinder heads flow over 400 CFM through the intake port, which is 30 CFM more flow than the production CNC ported LS7 cylinder heads.

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 30 CFM can increase engine power by 60 HP (30 CFM x 8 cylinders’ x .25 = 60HP).

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 Systems are developed as a complete system with custom designed camshaft profiles, ported throttle body and ported intake manifold and compression ratios that optimize engine performance

Comparative Analysis of BN7 NEDHEAD Exhaust Port Flow

BN7 Cylinder heads flow over 265 CFM through the exhaust port, which is 40 CFM more exhaust flow than the production CNC ported LS7 cylinder heads.

Technically, exhaust port should be at least 65% of intake port airflow to optimize the engines intake to exhaust flow ratio, required to produce efficient engine power and performance.

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 BN7 Systems are developed with the best custom camshaft profiles, exhaust headers and exhaust systems with high flow catalytic converters.
