    The Mach 4 Air Straightener for 4500 series intake manifolds is 1" tall. If you are mounting your SV1 on a 4500 series intake, the Mach 4 is just the ticket for maximizing power and throttle response. The Mach 4 is designed for the 115mm blade equipped SV1 to increase horsepower, improve low speed signal on low signal engine programs, increase throttle response and drastically improve part throttle signal generation. A typical 900-1300 h.p. engine will consistently show a 7-12 h.p. gain when employing the Mach 4 Air Straightener.

  • Part # PG-803 The PG-803 is nothing new. Its a professionally modified Holley regulator that's been used for years in NHRA Pro-Stock competition. Unlike look-alike regulators that make big flow claims yet still utilize the small seat area that froths and foams up the fuel.  We install a 50 percent larger seat area to reduce fuel bowl foam and stabilize the fuel pressure during high flow rates.  You get good clear burnable fuel and more consistent power from run to run. Once again simplistic design is the key to consistency and reliability. The PG-803 has enough flow capability to CLEANLY feed over 1000 horsepower!
  • Part # P26100 Air Pans fit between the carburetor and cowl area to keep engine heat away from and direct cool air to the carburetor.  A properly laid out air pan is typically worth 15-25 h.p. and really helps with consistency as underhood temps typically vary exponentially.  Oftentimes as much as 50-80 degrees higher over an outside ambient change of only 5-20 degrees. But building an air pan is tough and time consuming.  This pan really shortens your workload. With high side rails and and a long rear tray, this air pan requires only trimming to fit most applications. Actual Size: 24" Wide X 5" Tall X 28" Long Carb mounting flange is uncut so you can easily locate it in your engine bay.
