The wait is over...Detroit Rocker dyno results.

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

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 RPM’s 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 Thumpa’s 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.”



The Detroit Rockers are now on the website and remember, the first 40 orders will receive a free Detroit Rocker t-shirt.

GREAT report!

 

I have been waiting for something like this... I will be getting these along with mac longtubes!

 

Wow nice numbers.... so just how hard is a cam install on our cars? haha

 

very cool. how much longer on the blower grind?

 

Finally, cam tech is maturing for these cars.

Would be neat to see back to back runs vs. the FRPP cams.

 

so will these pass emissions

 

Watching intently to see what others get result wise???

 

Yes these are emissions friendly.

 

Thanks! Ok i need some right now haha

 

any word on the blower grind yet?

 

how much will these hurt my bumper to bumper?

 

So the minimal torque loss is only at low end, looks like a decent bump in torque in the top too.
Very tempting.

 

Do these sound better than the Hot Rod cams? And can they be used in a FI application?

Awesome work guys!

 

Nice work guys! Any ideas how these will do on a car w/ a CAI but stock exhaust manifolds?

 

I'm so close to pulling the trigger. Just about got all the money tucked away for these.

 

mods do not effect your warranty in any way, unless the dealer can prove that a given mod caused a given failure. you're better off modding your stang while it's under warranty; at least if something does fail, there's a chance that it'll be repaired under warranty. once your warranty's up, you have option but to pay out of pocket.

 

+1 Blower grind yet?????

 

I was wondering the same thing.

 

Guess we'll know at a later date!!!!
