Brenspeed's Custom Grind Camshaft (Code named the "Detroit Rocker")
#12
brenspeed, how do you think the cam you have out now would work with a blower, I know you have a blower cam coming out, I think there is alot of us that would like a lopey sounding cam that makes some power N/A and then when we wanna upgrade to a blower the cam would be compatible with the blower. I don't know how possible that is.
someone needs to make a start to finish video on cam installation, sr knight used zip ties and a broom handle to hold the sprocket then just just jambed the cam down my tightning each of the bearing caps really slowly and carefully, to me that sounds like a very easy way to do it, but I am still too chicken to do it.

This makes me also interested in comparison to other cams. It would be awesome to see some comparison dynos, but I guess thats a little hard for cams.
I'm no cam expert, but if the hot rod cams work well with SCs why wouldn't these? (see vid with Hot rod cams with wipple SC)

The intake and exhaust valve overlap is what gives cars that lopey idle that everyone loves. This helps increase volumetric efficiency in a N/A car because if the exhaust valve is closed, it is hard to fill the combustion chamber from the intake because its a closed system. However, in a forced induction setup, the intake air is being compressed first, so it doesn't need an open exhaust valve to fully fill the combustion chamber. When you have a large overlap with forced induction, you just leak a bunch of boost through the exhaust because the combustion chamber has already been filled. That is why really lopey N/A cams don't work that great with blowers.
Brenspeed, can you post a dyno graph of the before/after so we can see the results?

Every cam designed for the 3 valve engine require a new tune to adjust for idle/air.
Everyone involved in the "Detroit Rocker" cam is away at a NMRA race in Georgia. Once they are back, we will get some before/after dyno graphs up.
That car is running an O/R H pipe and Flowmaster Classic axle backs.
These cams are not regrinds, these are machined by Comp Cams and they do not use regrinds. Shims are not required either, they install like every other NSR cam made by Comp Cams.
If you do not plan on getting the blower for a while, it would be more beneficial for you to run the NA cams now, and with the blower instead of going straight to blower cams without a blower. The blower cams will offer 10-15 more power on a blower car than the NA cams (3-4 HP more) but will also loose more low end torque. We have a ton of customers running NA cams on blower cars and the gains are great. You will still see 30 hp gains with the NA cam on a blower car.
