Recommended Combinations:

S467/S480 - 1100+ RWHP Capable with Supporting Modifications - for high performance trucks that are raced on the weekends and see spirited / occasional daily driving use and infrequent light towing.

S488/S467 or S472 - 1200+ RWHP Capable with Supporting Modifications - for purpose built competition trucks that may see limited street driving to and from the track.

If you own a mild/lightly modified truck and are seeking the benefits of a compound turbo setup for frequent medium to heavy towing and with no plans to upgrade the fuel system further, please check out our S400/Stock Compound (Twin) Turbo Kit options.
