i was just reading an add for the powerdyne in some firebird catalog and it said because of its design using something like a turbo impeller that boost can come on as low as 1800 prm, this ad was for an LT1 kit. I alwayed heard that boost will not arrive until 3000 rpm, are there exceptions with different brands or does the amount of boost determine when it arrives

I dont know if it'll make boost, but definitly power.

On my '93 in 1st gear at about 2000 if you floored it the wheels would just break loose.

It can make boost that low but I'd rather go with a blower that makes boost in a more realistic range and more of it I used to have a Powerdyne so I can slam them.

I was turned on by this charger, but after doing some searching of past posts on its performance I am not to thrilled. I think for just a mild deal its great, but you can't get very high with boost, so if you want to upgrade, your outta luck. I waned the lowest rpm possible since its mostly a street car, but I want to push some serious power.

Not sure of your definition of very high boost but the Powerdyne can get you some serious push. Just like the other superchargers can provide when set up correctly. Also, I haven't really checked to see if ti makes boost at 1800 RPM but get to a 10 MPH roll in first gear (automatic, 3.70 gears, Nitto DRs) and slam the throttle and it'll spin the tires as hard as you care to.

I guess I'll just have to stick with my "mild deal" Powerdyne for a while longer.

Great, what should expect with 7-8 intercooled ATI? Tire meltdown?

I see you got a really good 1/4 time, I am very surprised, all the posts I saw had people pushing 315 horses or so. I see you got 400, what else do you have done to the engine? Hell If I can pull that much maybe all put this charger back into my consideration box, they are fairly cheap used and from the looks of it could give a nice bang for the buck

I have tried the powerdyne on a stock and modified motor. Like the guys have been saying, it's good for stock and thats about it. It had power, but not what I expected. You can't upgrade the blower either. No intercooler offered by pd and they told me you can't run more than 10#'s on this kit. If you want something that is fully upgadeable and has the power you crave, go with ATI. This was far more powerful than the pd kit on stock and modified cars. Fully upgradeable and intercooled. I installed both kits myself and the ATI did'nt take much longer. If you're going to spend the money, go with ATI. The price is not too far apart.

I made 480rwhp with a Powerdyne on my 383 but it made nearly 400 naturally aspirated. There was more power to be made but I had an FMU still with stock fuel lines and 30# injectors. I ended up selling my blower to pay for my 9" and fuel system
