The key to the whole deal is converter and gear ratios....everyone wants to put in a mega-tight converter to throw up a big MPH number, but a looser converter is easier to stage and will be more consistent on average tracks. The turbo combination can indeed be consistent; it's all about consistent boost control, as a small change in boost can equate to a big change in power/ET.

The downside to the turbo option is cost and complexity of the system. The Procharger powerplant is much easier to drive and easier to make consistent, without a doubt.

The Procharger system itself is also a little less expensive up front due to the lack of custom exhaust work.

The downside of the Procharger combination is that it takes a lot better engine components to make the power and have any sort of durability. A billet crank is mandatory, as are top of the line cylinder heads. A very good blower bracket system is necessary (5/8 and 3/4 thick brackets with 1" stands and B7 grade 7/16" studs are a must), as is a built-in crank support if a belt driven system is used (this will need to be incorporated into the blower brackets, as systems compatible with Roots/screw blowers won't work with a Procharger). You're also going to spin the engine a touch higher with a blower to make the combination happy, due to the camshaft profiles and converters used in these combinations.All this translates into more money on the engine side and more overall maintenance cost.

So, the question then becomes one of drivability, ease of tuning, overall cost, and maintenance levels.

The turbocharged combination, overall, is less expensive to build and to maintain.

The Procharged system, overall, is less of a hassle to tune and race.

Also, the cost of both total engine/power adder packages is pretty similar. For 2000 hp, you can expect to spend around $40-45K for the engine and its corresponting blower/turbo components. There will undoubtedly be those who will say "so-and-so did it for a lot less", but I can guarantee you that it's not going to be an apples to apples comparison. 2000 reliable, consistent HP out of a Pontiac with a blower or a turbo isn't going to be cheap. Can you make that power for less money? Sure. Is it going to run sixes at 2700 lb on every hit, on every track and be all-season-long reliable? Nope.

I agree with what your saying Travis. Since hes talking about TS racing. Which is still Bracket Racing. I think At this time The blower cars are alittle easier to keep consistant. But either way it takes time and $$$ to get either combo figured out. So its really the persons preferance on which way to go. I like both combinations. WOuld love to be able ot afford 2 cars 1 of each ;-)
