PowerNation: Engine Power Season 1 Episode 4 Top End Tricks

In this episode of PowerNation: Engine Power season 1, the team focuses on upgrading select parts of the engine's top end. The episode is aptly named "Top End Tricks" and explains how high-performance engines need a good top-end upgrade. There is also a tendency to spend too much money and deliver poor results. The show delves deep into how the team manages to get the balance right.

The episode begins by introducing host Mike Galley, automotive expert John Bouchard, and builder Tommy Faust. They highlight how the power of an engine is determined primarily by the top end and crucial cylinder head upgrades, which can significantly increase power without the need for an entirely new engine. Although the three hosts agree on this premise, they have differing opinions on just how much performance can be gained by retrofitting these parts.

The show takes viewers through various methods of improving the top end of an engine, highlighting cylinder heads' importance and how their modification can positively affect fuel intake, gas flow and the engine's power output overall. The show uses various high-performance engine examples, whereby this critical upgrade leads to increased performance, better throttle response, and enhanced fuel efficiency.

One of the methods explored in the show is increasing an engine's valve lift and duration. This is a fantastic trick as it leads to increased flow capacity and better performance. However, increased fuel usage also results from increased horsepower. The show compares the features of different cylinder heads to find the ones that are most conducive to increased performance.

In addition to the changes that can be made to the cylinder heads, valves, and cams, the show also explores changes that can be made to the intake manifold and fuel system, both of which also play an integral role in providing for better power. The team dissects various aftermarket options, from four-barrel carburetors to fuel pumps and intake manifolds to find the best options for increased performance.

Finally, the show highlights that increasing the power output is one thing, but keeping the engine operating at a safe temperature is another. The hosts test and compare various head gaskets to find the ones that offered the best cooling performance. The consequences of overheating, such as cracked headers or a cracked engine block, can be severe, leading to costly repairs or even engine failure.

The episode delves deep into how to increase the top end of an engine without breaking the bank. Through the use of examples, this is also demonstrated, showing just how much power is to be gained by implementing these upgrades. This episode is a great start for anyone looking to learn about engine upgrades to increase their vehicle's horsepower. It's entertaining, informative, and easy to understand, providing an excellent resource for car enthusiasts at any level of expertise.

In conclusion, "Top End Tricks" is an excellent episode of PowerNation: Engine Power season 1. The hosts break down various techniques used to increase the engine's top end, from retooling the cylinder heads to upgrading the intake manifold and fuel system. Anyone interested in learning about car upgrades and engine power will find this episode very informative and engaging.
