The Cams Yourself. You Can Also Add Two Cam Phaser Bolts &

phaser bolts are torque to yield so a pair of new bolts are required
during cam installation.
months of R&D we feel we have not only accomplished our goals
but exceeded them. We are very excited to offer these camshafts as they
do not require phaser limiters and do not require aftermarket valve
springs. They sound great, drive great at low rpm, and offer great
power gains as well. Our test car picked up 26 rwhp peak vs. peak and
34 rwhp when comparing stock vs. Detroit Rocker at 6,500 RPMs running
the stock air box. We then added a JLT 110 mm intake the gains sky
rocketed to 40 rwhp gain peak vs. peak when comparing the JLT 110 mm
intake & Detroit Rocker combo vs. Stock air box & Stock
cam combo. The test car for this graph was a 2006 Mustang GT manual
running 4.10 gears, Pypes long tube headers, and a Brenspeed tune.
is a quote from Chandler at Brenspeed : I
ran Comp Mother Thumpas and phaser limiters for a year and half. I
loved the rough idle but I didn't like low rpm roughness when driving
through the city. I also had to constantly slip my clutch to compensate
for the roughness when accelerating because of the controlled mis-fire
and the cams grind. I ran a 4.30 gear to help make up for the loss of
torque as well with the 127020 cams. I removed those cams and went back
to stock 8 months ago. I now run a 4.10 gear and the new Detroit Rocker
cams and I have never been so happy. They lope like the classic muscle
car sound I love and had with the thumpr cams, yet drive like stock. I
can now drive in a low gear and no longer get the lopey cam bucking I
had before and also take full advantage of variable cam timing because
the phaser limiters are not required with the Detroit Rocker grind.
with all cams a lower rear gear is suggested.
