Wilson
Manifolds has recently announced three stages of ported cast aluminum
intake upgrades and a new, trick, high-flow D-Shaped fuel rail for the Mitsubishi EVO.
Using
a factory cast intake manifold, Wilson provides a mild street stage and
two full-race stages—one designed for 8,000 rpm the other 9,500 rpm.
Wilson, a leading name in performance and racing induction systems,
has expanded its repertoire and announced an amazing new intake system
for all 5.9 liter common-rail Cummins engines from 2003-2007.
Depending upon the state of tune, the Thrasher can generate in
excess of 300 extra ft-lb of torque, or with lighter throttle use, the
equivalent in fuel savings.
In contrast with the OEM arrangement, this new induction system
provides greater equality of air-fuel distribution, especially in the
cruise zone of 2,000 to 2,250 rpm. As a result, the Thrasher generates
not only amazing gains in both torque and fuel economy but also
improves horsepower output, lowers exhaust gas temperatures, reduces
exhaust emissions, and improves drivability.
To avoid diverting their efforts to additional mid-season testing, KB Racing will debut a third Pro Stock race car at this year’s US Nationals. The car will be run by KB’s induction specialists Wilson Manifolds of Fort Lauderdale, Florida. Wilson Manifolds and KB Racing have enjoyed an exclusive arrangement since the team’s inception.
