Thanks Dwight for the shortest,most descriptive reason we're in the boat we're in.

Dwight and Ed:

Thank you for your responses. If you're right, why doesn't Bob Shaw own two of these Neons???

Maybe I'm dead wrong, but it seems to me that the fault, in this case, lies not within the factoring system (and therefore the classification,) but the amount of boost available to the engine. These turbocharged engines are factory-rated at the boost levels dictated, to give minimal warranty problems, and in certain instances, it is possible through engine parameter manipulation, (cam profile, fuel delivery rates, ignition timing, etc.) to increase boost levels with OEM equipment, which can increase power output, dramatically and concurrently. A 150 horsepower engine (normally-aspirated) when treated to 15 pounds of boost, becomes a 300-horsepower engine. Give it another 8 pounds of boost, and it picks up another 75 horsepower. This is not my opinion, but rather seems to be generally-accepted theory according to several books on turbocharging theory, by authoritative sources.

My contention is, Mr. Blossom has, in true hot rodding fashion, has found the combination that will produce horsepower far beyond what would be generated by that engine at factory boost levels. As I have said, this is only my opinion; I don't claim to have any information beyond that.

But, if I am correct, a tell-tale boost gauge placed on the engine by NHRA, would go a long way toward rectifying this problem without resorting to re-factoring the engine. All it takes is a vacuum line and a gauge. But NHRA hasn't seemed to be pro-actve in pursuing this path... Surprise!!!

Food for thought....
