If I want good vacuum, idle and gas mileage, what cam specs should I look for to maximize power while not ignoring the previous requirements?

Here are some cams I think might be a good fit:

GM 12565308 204/218 0.550/0.550 117.5
Comp 54-535-11 210/218 0.513/0.507 115
Lunati 55002LUN 212/221 0.510/0.510 116

Look at ECS, EnglandGreen or Brutespeed. They all have cans designed for a cenrti blower

I took a look at these suppliers.
For a S/C, I thought the intake duration could be shorter because intake air velocity is much higher and more dense than N/A. I'm suprised ECS's blower cam has equal duration intake and exhaust.

Comp has centrifugal S/C cams, but they are all really high duration with lots of overlap. I'd guess these would have poor idles, poor gas mileage and not much vacuum (poor brakes).

look into the LINGENFELTER GT1-1 awesome results on my na car and my buddys procharged camaro

229/242 0.631/0.631 114

looks pretty similar to the Comp 54-477-11

227/243 0.614/0.624 114

how is your idle and fuel economy?

Google England green whiplash, the specs are on corvette forum along with their other cams. Look up dascorcha247 on youtube, he has that cam in his vette

I would use the Comp grind out of these 3.

I've been running a Comp set for c blowers in my 32V since '07. Idles @950 with a great lope, no vacuum problems and 563WHP...they were great to work with on application. For what it's worth...oh yes, a 4:10 with a Viper 6 spd, 24 MPG at 70 on cruise control...10 around town, who can keep their foot out of it?

I couldn't find specs, but I found this

Here is our new cam lineup :

* EnglandGreen Havoc Cam™ : wreak havoc with our new creation cam in the high 220/low 230s duration range
* EnglandGreen Mayhem II Cam™ : formally our Mayhem Cam™, but now completely redesigned - and much larger! Duration is in the low 240s range.
* EnglandGreen Whiplash II Cam™ : Best Seller!! Duration in the mid 240s/mid 250s and extremely aggressive.
* EnglandGreen Chaos II Cam™ : formally our Chaos cam™, but completely redesigned and significantly bigger. Duration is in the mid 250s
* EnglandGreen Black Rage Cam™ : Our latest creation. For use only in big cubic inch motors. Duration is in the high 250s/low 260s duration
* EnglandGreen Insanity Cam™ : This cam is for the seriously mentally disturbed among us. Duration is in the low 270s

I ran their Mayhem II cam. Not a bad cam in my Z06, but no way I would run one again. I liked it at the time, until I learned about what makes a car go fast. A dyno is not part of it. If a tuner has never made a 1/4 pass, then I would advise not going with that cam.

I speced my own blower cam myself, and while not the best, it does the job on only 12psi.
