The increase in power was made possible by the engine's improved volumetric efficiency through reduced intake load losses and by exhaust backpressures, together with optimized electronic control.
If you have a backflow issues (high backpressure) or even a timing issue where the valves are not opening and closing at the correct time (slack chains, jumped timing), your MAF sensor readings will reflect this as well.
A Chevrolet Performance exhaust system with a polished 4 - inch outlet offers a throatier exhaust note and reduces backpressure by approximately 14 percent.
rich / lean though, you'd need to set up the carbs again with any drastic change to backpressure / airbox removal, so check that out anyway.
That's despite only nominal gains in horsepower and torque, accomplished via reduced exhaust backpressure and the latest Bosch engine management system.
Camshaft, intake manifold, turbo, and exhaust systems are where you create the flow of air, and when you create the backpressure of engine — and in this part is only Lamborghini, done for Lamborghini — and there is a reason why only our V - 8 has 650 hp and 627 lb - ft at this level of rpm.
