BEANS DIESEL 220880-10 DOMINATOR 66 TURBO WITH BILLET COMPRESSOR WHEELBeans Diesel Performance D66 is the ORIGINAL true DIRECT bolt-on high performance turbo for the 94-97 OBS Power Stroke. This is a high performance stock replacement turbo. This upgrade will improve the air flow from the stock 750CFM to over 1050CFM! That is a 30% air flow increase over stock which translates directly into lower smoke levels, lower exhaust gas temps, (as much as 300 degrees) and more horse power. The D66 can be used on stock HP levels all the way up to over 500hp! And now that we include our new Milled Billet Compressor Wheels the D66 is even better with more TQ, more HP and a flatter HP Curve! Don't be fooled by cheap imitations. This is the original D66 and of course the best!
