Lots of Procharger fans in here... I'm biased towards a Magnacharger kit. I've never owned one, but I have owned a Procharger. I like the Magna's for the instant torque, clean install, eliminates the intake manifold, etc... Procharger has it's benefits too. Again, it's all about your goals and budget.

 

The Whipple kit seems to be a bit much on the work side for the power you get from it. If I were to buy a Maggie Id go TVS1900 or 2300 depending on what motor it was going on. A buddy of mine is working on finishing his forged 383 LS1 and he has an F1A on it. Its all what you know and what you want.
