Said it before, say it again, Paxton lied like a rug in their adverts and promotional materials. The 40% increase claims began when they put one on a 239" 100hp flathead Ford. With a lot of other changes, it made maybe 140 horsepower. That 40% increase was so impressive, they kept it in the ads. However, on bigger OHV engines, it was a flat misrepresentation. I've done a few supercharger installations, complete with boost pressure gauges and a couple of before/after dyno and drag strip tests. Even on a small OHV8 engine like a Stude 289", the Paxton did not increase horsepower 40%. The strip times don't lie and the increase was never more than 20-25%. On the larger displacement Packard 352"-374", the Paxton won't make 5# of boost. The 12# high-output units John Erb references are race-only units and at 12# of boost, have operating life spans measured in hours, not years and thousands of miles. I've had many conversations with John on the Paxton and he agrees it was all we had back in the day, but that day is past and there are many bigger, better units available today.

As always, your car, your money, your decision.
