QuestionGood day to you Mr. Peterson. My question is, does a stock engine which undergone basic modifications like utilizing a simota air-filter, racing muffler, customized exhaust manifold or headers, and a bigger diameter high tension wires really add more horsepower? Thank you sir!
AnswerIn the strictest sense, it may not add horsepower, but rather frees up, and minimizes the loss of horsepower your engine produces.
Residual losses from poor design, and mass produced lower quality components can add up, these products are built to exacting standards, with high quality components. They can be costly, but modern engines are very limited in what can be done, as they are built from the inside out if you will, with economy, drivability and emission standards orchestrated together.
These mods won't drastically affect any of this, and you'll probably notice an increase in gas mileage.
In this catagory of mods, synthetic oils wherever they can be used will free up otherwise wasted friction.
Computer control improvements, be it a "chip" or onboard adjustable parameters, are of dramatic help also.
As a rule of thumb, keep in mind if any part is worth the "bang for the buck", meaning will the cost give me a realistic increase in performance. Manufacturers do tend to advertise their best case scenarios, say, if they claim a 30 percent improvement, if you expect half of that, you'll usually be happy with the results.
Hope this helps, thank you for your courtesy.
Sincerely;
"Blue" Mike Peterson
