SO CLOSE!

We saw extreme boost levels in our quest for horsepower from the little supercharged V-6 with out ’94 Supercoupe. With the Magnum Powers MPx supercharger clearly capable of more airflow than we could support (boost climbing north of 23 psi), it made sense to work on the heads-and-cam combination to better deal with some of that boost.

IN WITH THE GOOD AIR

When a B16A-equipped CRX EF came into the Rage Performance shop for a Skunk2 intake manifold install, the crew dove into the job with a fury. With cameras at hand to document the swap (’88-’91 CRX) for your personal pleasure, the job took no time at all and the owner of this Honda is deliriously happy with the results.

Time and time again, our advice to those interested in learning about stout-running engines is that it’s the total combination that makes it all happen—considering, of course, that components are prepped, cleaned and assembled as if in a “clean room.” 

CARB OR EFI?

What makes more power: carburetors or computers? While the ultimate answer is that a sophisticated electronic fuel-injection system will virtually always outpower a carburetor, the real question may be whether the power gains are worth the extra expense and complexity of installing an EFI system.

COAST-TO-COAST 482ci STREET 409

You can drive this bad boy coast to coast and burn all the rubber you want in between.” That was Day Automotive’s Tony Shaffer proclaiming the abilities of his shop’s 482/409. Soon thereafter, we were entering the confines of Day Automotive in Independence, Missouri, where Shaffer and crew had just completed the engine in seven days. It represents what can be accomplished power-wise with the right combination of parts, plus some internal modifications. And with a 10.0:1-compression ratio, it’s very street-friendly.
