New
XFI™ Camshafts Deliver Big Power Increases For
Late-Model Chrysler Hemi 5.7 and 6.1-Liter Engines
Three
different camshaft combinations net power increases
up to 61 HP
COMP Cams® New XFI™ (Xtreme Fuel Injection)
camshafts for Hemi-powered Chrysler vehicles dramatically
increase engine horsepower and torque, yet retain compatibility
with reprogrammed OEM vehicle computer systems. Available
in three different profiles (XFI 260, 268 and 273);
the
new camshafts are application-specific with designs
for street performance and towing.
In recent
dyno tests on a Hemi engine using COMP’s #26918
beehive valve springs and upgraded exhaust, the XFI
260 netted 20 additional ft pounds of torque in lower
rpm ranges with a peak of 31 additional hp. The XE 268
camshaft added 14 ft lbs of torque at low rpm and 47
additional peak horsepower. The amazing COMP Cams®
XFI 273 camshaft yielded it’s most significant
horsepower increases over 4500 rpm generating 61 more
horsepower than the stock Hemi 5.7-liter engine.
“We’re extremely pleased
with the power gains we have achieved with these camshafts,”
said Scooter Brothers, VP of Engineering. “When
we set out to offer specialized Hemi camshafts, we had
an acceptable power increase figure in mind. We have
far exceeded that original target figure and believe
that these three camshafts will offer customers the
ability to find the exact camshaft that is right for
their vehicle, car or truck.
