Shelby GT500 at PSI

by Kyle Tomita on Tue, May 10th, 2011 | Client Vehicles, On The Dyno, Tuning

A client of ours brought down his Shelby GT500 to the shop.  The Shelby came in to have the carburetor tuned.  This Ford 428 has a Holman and Moody race set up with twin dual Holley carbs.

Guess the cars in front of PSI May 9th 2011

A Technician removes the carbs to rejet them.

He rejetted the primaries and secondaries.

After the carbs were back on, Russ checked the air/fuel ratio and adjusted the timing.
