HaHa...buy Ford parts and you won't have this problem in the future . Sounds like a huge hassle for all that 0hp you'll get from them!



Any dyno results to back up your negativity?

Ignition Wires
Ignition wires are free in Solo's Stock class: the rules state they may be replaced with pieces of any origin. From the data we've collected, it's a
worthwhile modification.
Replacing the brand-new stock wires on our BMW 318ti project car with a set from Magnecor gave us around two additional horsepower at the
drive wheels, while our Neon got a three-horse bump when we replaced the stock wires with some hot ones. Installing a set of performance wires
on our Honda CRX project car didn't unleash any more power, but the new horsepower curve was both smoother and no longer fell away at the
top end.
In testing with a variety of cars at our Dyno Day events, we've found that nearly every vehicle benefited from having the stock wires replaced with
quality aftermarket pieces from companies like Magnecor or Ignition Equipment. We found consistent power jumps in the two- to three-percent
range; that's pretty significant. Plus, performance spark plug wires don't cost that much. Figure $50 to $150 depending on the application.





Yeah, and you can put a car on a dyno and vary 2-3hp from run to run without changing anything...



So says you. How much dyno experience do you have? Statistical analysis?

If dyno results varied about a mean by 2-3 hp, then you would have some below and some above, and over time, would arrive at a pretty good estimation of reality. Even a 2-3 hp variance would not account for consistent, repeatable 2-3 hp gains.

While you can expect the numbers to vary a bit from run to run on the chassis dyno (usually less than one horsepower), when you see a consistent two-horsepower jump, you know you have something.
