Brenspeed Detroit Rocker Camshafts

The Detroit Rocker camshafts by Brenspeed were designed to meet 3 specific needs.
1. Rough Idle
2. Great drivability
3. Minimal Torque loss with a great power gain

Use The drop Down Boxes Above To Add Freedom Racing's Cam Installation Valve Spring Compressor & Timing Wedge If You Plan To Install The Cams Yourself. You Can Also Add Two Cam Phaser Bolts & Assembly Lube Which Are Required During Installation. Factory cam phaser bolts are torque to yield so a pair of new bolts are required during cam installation.

After 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.

Here 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.

As with all cams a lower rear gear is suggested.
