Re: Next Debate.
Guys,
I'm going to let you in on a little information;
1) Yes, more boost can make more power, but just like your air compressor, pressure makes heat, there is a point where the gains in boost are artificial due to the added heat. Tim Kish can tell you exactly when this occurs.
2) If you work on flowing more air into your cylinders, your boost actually goes down, and get this, your power goes up. So give up on the boost limiting idea.
3) Superchargers are not controlled like a turbocharger with a waste gate, therefore the manifold pressure changes with atmospheric pressure, it simply increases the atmospheric pressure by a given amount irrespective of barometer. Bottom line, the supercharged cars behave just like a normally aspirated combination with changes to weather. Turbocharged cars use the waste gate to control to manifold absolute pressure, and therefore can maintain consistent boost pressures regardless of atmospheric pressure.
4) Do you know why most of the "desireable" combinations in Stock and Super Stock are primarily based on engines that were not the "Hi Perf" versions like the '70 LS-6? They are based on the weaker lower performance offerings. The weaker engines are farther from their ultimate performance potential. This is where the NHRA's horsepower factoring system is flawed. The high performance combinations are handicapped from the minute the numbers hit the book. The new engines coming from the automakers are all high performance and are way closer to their power potential than any of the engines from the musclecar era.
That's all for now.
See you at the races,
