Turbo Cam, aggressive sound??
I was wondering if there is that aggressive sound with turbo cams as ther are with N/A cams. I like that loping sound but I would think the attributes that cause that sound would not be benificial to a turbo system. Is this correct?
I know that most people recommend stock or close to stock cams for low boost applications (did a search already!), but is there a turbo cam out there that has an aggressive sound and will still work well with a turbo?

anything will work with a turbo. However, a cam with less overlap will keep the boost from blowing out. If you do go with a high overlap cam, then you'll probably need to increase the boost pressure quite a bit

Out of all the cams I've tried, the ones with the most overlap made the most power. (at the expense of low end response)
This cam made the power in my signature and sounded a bit lopey. (I've since switched to a smaller cam for smoother driveability)

I have a 224/220 on a 114 in my car and It idles fine, no lope. I have been able to get away fine with an almost stock MAF table, changing only the injector offsets and constants. I have stock drivability as well.

A [very] well tuned turbo motor will have the same backpressure as boost. Typically, though, backpressure is 1.5 - 2 X boost pressure, so overlap can allow exhaust to travel back into the intake port.
With a good turbo set-up, overlap should only help power because, with the same exhaust and intake pressures, there won't be any over-scavenging or intake dilution. The overlap would, however, help exhaust and intake flow by reaching peak lift closer to peak piston velocity.
