Precision Turbo’s New Billet Wheel in AJP Turbo Kit

Comparison of Precision Turbo’s Cast and Billet Turbo Wheel

While at PRI 2008 in Orlando FL last week, the Precision Turbo folks showed me the differences  between the cast wheel in the older designs and the new billet wheel. One of the big differences is the size of the spindle in the center. The cast wheel has a larger surface area. By contrast, the billet design reduces the size of the spindle so that there is less air resistance.

The billet wheel is noticeably lighter than the cast wheel. Less weight and lower air resistance translate to less turbo lag and more power in the low rpm range. This new billet wheel is part of the new HP Technology Series 6262S turbo that was covered here. We at AJP are glad that we upgraded to this turbo.

By the way, you may see the 6262S referred to as SC6262S. This is incorrect. “SC” refers to the “Sport Compact” series. AJP’s older turbo, the SC6169E was in this class. But the new 6262S is not.

When I asked the Precision Turbo folks about this, I was told that it could technically be called the HP6262 but that has never caught on. It’s just called the 6262.
