Power
I have been reading alot on SC lately and still have a lot of questions? I know Centrifical type start building power around 3000 RPM. At whay point does the Magnuson start building power? Also it seems to me that building power at a lower RPM will preserve your engine over the long haul.
Thanks,

Re: Power (TheBigDog)
The power starts as soon as you plant your foot. I have not ridden in a centrifugal S/C car, but I have ridden in an LPE TT (550 rwhp package). There is a slight lag in those cars. There is no lag in the Magnuson. Of course, those others have really impressive #s at the high end.
Here's my dyno, as an example:

Re: Power (SteveL2)
Well, it depends on what you are calling high end HP. The ATI produces more HP than the Magnusson from 3k to redline. If you are below 3k, are you really using the boost anyhow?
If you do a search, there is another thread that shows the normal TQ/HP curves for both SC's and compares the power output from both. After seeing that comparison, I decided to go with the ATI. My .02 cents. :cheers:

Re: Power (TheBigDog)
They are two completely different blowers. You just have to ask yourself what your plans are for the car now and in the future. The Procharger has huge potential for growth while the Magnussen seems to be better in terms of install and having very few issues. What do you want to do with the car?

Re: Power (Red C5)
The ATI does boost later in the RPM range and it is accentuated by H/C and LT headers. With the addition of the later you don't need boost up to that point and once it kicks in---like a jump to lightspeed and it won't quit pulling. Another advantage is with the mag making so much power down low, traction is even worse and with my setup and the ATI--I have no idea how the magnacharger crowd keeps it aimed where they're going!

But, my car will likely never see a track (at least while I own it), so the power it provides for a daily driver is plenty for me. Also, I only care to go back to my tuner (21st Century Muscle Cars) to admire their other cars, not to get my car tweaked constantly, or to put on add-ons to overcome the problems that ATI continues to this day not to address. I do admit, however, if my Magnuson ends up having maintenance or reliability problems, then I'll be pretty disappointed as I gave it very strong deference due to the lack of reported problems in the many LPE installed units that are out there. :seeya

Re: Power (SteveL2)
Thanks Steve. . .that is the one! :yesnod:
Basically, it shows the Magnuson and the ATI making the same HP at 3k and above 3k, it's not even a close comparison.
I am curious, if you idle at roughly 1k, and slightly pressing on the gas yields 2k, then when you mash it, I would guess that the RPM's will jump to approximately 3k? If that is the case, would you ever really see power below 3k?
For those, like myself, with an A4 if you simply get a torque converter then you will not. For those with a clutch, even from a dead stop the start would be approx. 2500-3000 RPM's.
It seems to me, the useful power band, if your not racing, would be between 3-5k? Also, as you can see from the charts posted in the other conversation even at 2600RPM's the Magnusson only produces 5 more HP?
Again, thanks for posting that comparison. . .the numbers speak for themselves. :cheers:

Re: Power (TheBigDog)
BigDog,
I guess the numbers posted in the other conversation will answer your questions?
It appears that the Magnuson and the ATI both start around 2600RPM's, at which the Magnusson is ahead about 5hp. . .caught by ATI at 3k. . .exceeded by ATI by approx. 100hp at shut down! :eek:
Good Luck. :seeya

Did I give up a lot to the ATI cars? Yes, certainly those that are going higher on boost. Do I care? Nah, not much, so long as mine stays reliable.
All I can really say is, next time you're in the DFW area, look me up, and you can see for yourself. :cheers: I won't be running 10s, but I'll be smiling back and forth to work, which is where I spend almost all of my drive time.
