Brenspeed Detroit Rockets S/C specs

[Manny]

I could not locate the specs for the DR S/C camshafts in the database at COMP CAM, but got these specs from their customer service dept:

cool

 

[Pumpkinfish]

What do they compare with on the market?

 

[racevert]

Are they anything like Brenspeed Detroit Rocker Camshafts?

 

[Manny]

Not worth replying

 

[navyman8903]

could you get the LSA also?

 

[bolivianpimp]

Yay! I been looking for this, i called brenspeed to ask them and they said it was confidential and couldnt tell me. WTF doesnt all cams come with a cam spec card?

 

[blue streak]

i like brenspeed. but that makes me laugh. i wont put a set of cams in my car unless i know the specs before hand. and if someone has the ability to grind copies of their cams, im sure they are capable of measuring one of their cams lol.

 

[tigerhonaker]

interesting

 

[Jeffs FRC]

LOL, Brenspeed is gonna be pissed that comp's cust service gave out their super secret specs!!!

I've bought stuff from Brenspeed and agree they're a great shop to deal with, but not telling customers the specs of the cams they're installing in their cars is kinda retarded. If a competitor REALLY wants the specs they will have them easily. Anyone ever hear of a cam doctor?

Not worth replying

Why is it not worth replying? WTF

 

[US-1]

Anyone ever hear of a cam doctor?

Got one.

And on a professional level......this is precisely why I don't have Comp grind a proprietary camshaft design for me. Dumb fuckers will tell anyone that calls pretty much whatever they ask for.

Makes Pefect Sense !!!

I bet Brent just LUVS the fact that Comp released this info. on his
New Cams after the Time & Effort he put into getting them right.

Yeah they might be pissed, but at the same time brenspeed should make it available to customers so they can know wtf they are buying and if that cam is right for their application. Every other cam has their specs listed out so you can see if its right for you, i think brenspeed just didnt want people getting a tune elsewhere so they think if they hold out on specs you will get a tune from them

 

[808muscle]

, i think brenspeed just didnt want people getting a tune elsewhere so they think if they hold out on specs you will get a tune from them

Wont be long before other tuners get brenspeeds cams on their dynos and learn to tune them. Competition is great.....we all get better products at a competitive price.

These are specific for S/C cars? I didn't realize they had N/A and S/C design.

And you are in Y-town? I'm always there...

Yes, these are for a S/C. They have both types now, check Brenspeed's website. Today the car is at Rocket Performance of Yorktown. The cams are now installed and tomorrow we go on the dyno.

 

[Alter Ego Trip]

Sweet. Can't wait to see the numbers with the new cams. I've been tossing those around.

 

[Manny]

I'll post the dyno results on Friday. I'll using the Brendspeed mail-order tune and a custom tune by Rocket Performance.
