Blower cams typical have less overlap than NA cams. The valves don't open together for as long. I don't know first hand what kind of power you would loose. But if you can I would swap it out for another. Maybe you can find a low mileage used, or if you have to trade! How far are you from boosting, if at all?
I know that boost on NA cams, its harder to build boost because you are just pushing it right out during the overlap. From what I have seen its a pretty big loose at higher rpm's/boost. But like I said I really cant answer it the other way around
See i'm doing just the opiset.. i have a nice N/A cam(SRTMAX) and going supercharger.. not a very good cam.. but i LOVE the rumble it makes ..so i'll give up a few ponies to keep the rumble.Theres no drag stips around here anyway.
She will feel a little soft with a blower cam but only when compared to a bigger one... if your for sure boosting next year then I'd throw it in now so you are ready while the motor is out. If you are 50/50 on the boost next year then stick where you are at or go with a big cam and switch it up when your ready to boost. Other than install you never really lose much on a cam to be honest...
No the cam alone doesn't and I'd say for right now your fine without one... you will want to consider a stall when you boost to match the charger you put in, some like a higher spinning centrifugal will like a little bit more stall, others like a KB and Maggie won't need it add much as they are going to provide some pretty gut wrenching torque from quite low down. What blower are you considering down the road pal?
