Detroit Rocker Supercharged Camshafts
Detroit Rocker camshafts by Brenspeed were designed to meet 4 specific
Rough Idle 2.
Great drivability 3.
Minimal Torque loss with a great power gain 4.
Up to 30HP gains typical
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 supercharged test car picked up 30+ rwhp peak
vs. peak and torque increased all the way to redline. The test car for
this graph was a 2010 Mustang GT manual running our Saleen supercharger
and long tube headers.
is a quote from Chandler at Brenspeed on Detroit Rockers N/A : 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
