Austin-Healey 100 With Blown Jaguar V12 Has Almost Enough Engine Now

The Austin-Healey 100 is a true British sports car, all right, but there's something missing. What could it be? Yes, of course- a Vortec-supercharged 5.3 liter Jaguar V12, which is what Canadian lunatic Martin Jansen has installed in this '54. We don't get any horsepower figures for the engine (which seems odd, considering the engine builder goes by the moniker of "Dyno Dave"), but it's a safe assumption that it's much, much, much more than the 90 horsepower of the original A-H four-cylinder. The build quality here is just staggeringly good and the whole setup somehow fits neatly under the hood. We have no choice but to give this engine swap an extra heavy-duty Jalopnik Stamp-O-Approvalâ„¢! [BritishV8.org]

PCH, Power-To-Weight Edition: V8 Peugeot 403 or Blown Beetle?

The Dirtbag XJ-S pounded the Sepia 1940 Mopars like a Canadian carny pounding a case of Moosehead in yesterday's Choose Your Eternity poll, which was about what we expected. After all, a V12 Jaguar can beat most any PCH contender, up to (and perhaps including) a Citröen. We'll test that hypothesis later, but today we're going to try our hand at Hell Projects featuring lightweight vehicles with hoon-centric engine power. You see, you need to consider the possibility- however remote- that you might one day crawl out of the crater of boiling sulfur in your garage and actually finish a project. At that point, the hell must continue, as you careen out onto the public roads in a barely controllable deathtrap pawing and snorting at the ravaged pavement with ten times the horsepower its designers intended.

PCH, Personal Dilemma Edition: Love (And Fear) The One You're With

This series got its start- and continues to be so much fun for me- as a result of my own search for just the right personal Project Car Hell; I came close to buying the 20R-powered Austin Healey Sprite in the very first PCH, and I've been searching ever since. I considered and rejected the '65 Falcon wagon, and now it looks like my cousin might take on the '68 Torino GT himself. But then I realize that I have two machines with Super Sleeper Potential right under my nose: my daily-driver 1992 Honda Civic DX and 1997 Ford Crown Victoria P71! Why, I could turn either one into a ragin' dragstrip monster with easily-obtained hop-up gear right off the shelf! Gadzooks!

Adventures in Turbocharging

We're not sure if this guy is a comedic genius, or has more than a few intake manifold bolts coming loose. The poster surmises that since turbochargers are at best 80% efficient, channeling engine exhaust directly back into the engine would be good for moar power. If anyone has a v-band clamp that will bolt an exhaust header directly up to a Corvette cross fire injection intake please let him know. He also seems concerned about the correct pinion angle given all that potential horsepower. [Direct Exhaust Injection via Nebraska GM Modern Muscle]

Huffed at Two Speeds! New Supercharger Features Transmission

This is truly a cool piece of hi-po tech geekery, and it's so simple, we don't know why anyone hasn't tried it before (or at least why we've never heard of it). The pocket-protector advocates over at Atonov have come up with a centrifugal blower (which operates like a crank-driven turbocharger) that uses a transmission to change the rotor's speed depending on engine RPMs, resulting in improved boost matching throughout the rev range. Totally donk-stompin' awesome. More »
