Neat.

Not to downplay the vapor system but I notice it also says 250 hp at 5200 rpm... Just FYI the pontiac 151 "Iron Duke" in fiero setup has about 90 hp (tho 135-140 ftlb), a redline of 5k rpm, and nothing left by the time it gets there so this is NOT a stock motor by any means. Making an NA engine that much MORE powerful (read, volumetrically efficient) alone would help mileage.

I'm not sure I would have attempted a vapor setup in a Fiero. I always thought it was ironic that Fiero was Italian for fire, as many of them burned up.

I've read up about this car a few years ago and the reason for the huge increase in power is that it was turbocharged.

like most reputation things, very few actually burned up (only 200-300) but they gained a lot of media coverage. Basically, GM designed it as an economy car and people tried using it as a sports car. Small oil pan, low revving engine +people revving the snot out of it and lots of sideways Gs caused oil starvation, chuck a rod, catalyst is right next to the engine where the rods usually exit, hot oil on hot cat=fire. GM's successfully solution was a bigger oil pan and filter to increase oil capacity.

Cool

From the sales literature it doesn't appear to be marketed as an economy car, and in that era, didn't Pontiac call themselves "The performance division of General Motors"?

well it wasn't exactly a performance car with under 90 hp and a 3 quart oil pan. the V6 GT version came later when they figured out people wanted to go faster.
