What are the differences between these two setups? If I had two stock C5's 6spds, and put a magnacharger setup on one, and a procharger setup on another, what would be the differences in hp gains, performance, and what are the pros and cons of each setup. I've always wondered what the difference would be between the centrifigul (sp?) and the roots type blower. Thanks.

The Magnacharger is a great street blower with instant boost and low end torque.

The ProCharger is a more serious street/race piece, with superior air flow in the upper rpm ranges.

In a impromptu stock vs stock street race from a roll the Magncharger would get the jump on the ProCharger, but the ProCharger would catch and pass him.

What about hp gains? What are the average gains for the magnuson, and the average gains for the procharger?

You would be better off to get on the phone with a tuner that installs both units, that way you can have results that are based on the same dyno and location.

Roots type blower has lower HP potential with better low end torque. Centrifical offers much higher HP potential but higher in the RPM range.

Too many variables: boost, with or without intercooler, intercooler type, headers, standard install or custom install, type of bracket for ATI (belt slip issues), tuning, tuning, tuning. Do yourself a favor, set your goals then talk to a tumer to find out how to obtain those goals. The more RWHP the greater the chance of breaking something.

Very few people just bolt on the base kit for either the Mag or the ATI. Pretty soon folks are messing with boost and other mods. So, the comparison becomes apples to oranges. ATI has more more adjustability upward but I think there's also then a question of which unit you go with, and as stated above, the higher you go, the more stress on other items and, hence, greater chance of damage and greater cost. The Magnuson certainly has its benefits as well.

Bottom line if you stay stock bottom end go w/ magnuson. Want more than low 500rwhp, build your bottom end & go w/ ATI.

you have to get a hi-rise hood with the magnuson, that's something to consider as well. i like the ATI because I like the original hood the best of all hoods. that's one of my goals

An intercooled Magnuson will gain you a very respectable 130 RWHP (approx). The ATI has more potential to adjust boost upwards, you could get very large gains if you planned on building a forged motor down the road.

If you want something kinda low maintenance, are satisfied with Magnuson numbers, willing to change the hood.... you might be happy with it.

If you are the kinda person that gets bored of a certian level of performance and then wants more.... the mag would be a bad choice (in my opinion). The ATI could possiblly give you more headache with trying to get the hardware set up right.

Then of course there is always TURBO

Since everybody did a good comparison already, I'll just add my experience with centrifugals that in general, the centrifugal mechanical S/Cs really shine when you're looking at peak boosts of 8-9 psi and higher. The smile factor between a 8-9+ psi system vs. a 5-7 psi system is huge. But 8-9+ psi requires lower compression and forged lower end if you want to have a truly comfortable safety margin for top-end runs/pump gas.

The thing is, motor work (even budget motor work) + centrifugal can quickly total up to the ultimate solution of twin turbos. So there's a narrow margin of centrifugal S/Cs being the sole ideal choice. And the introduction of the IC'd Magnacharger along with appropriate cams, etc. narrow that window ever so further on the other end. Mix in great performance at somewhat lower refinement of highly developed heads and cam NA pkgs. and the argument really gets confusing.

Because of what's said, I think a re-sleeved 427cid big centrifugal blower package for possibly $30,000 installed/parts/tuned is the strongest case for mechanical centrifugals where nothing else for all-time/on-demand power comes close until you spend $50,000+ for a 427cid twin turbo setup. That big gap between $30,000 and $50,000 makes a 427cid centrifugal blown setup a standalone choice.

So maybe a good route could be:
$5000-$13,000: H&C NA Pkgs. with some compromise in refinement
$7,000-$14,000: Magnacharger (with or without IC'ing) with blower cam or Vortech SQ blower if you want a sleeper/stock hood setup.
$14,000-$18,000: Bigger ATI blower, fully ported heads, blower cam, budget built lower end, etc. Any more than $18,000 and it's worth to step up to a 550TT pkg. or a 427 NA if you don't care too much about top-end straights but have a bit of road racing desires.
$20,000-$25,000: LPE 550TT
$30,000: 427cid resleeved LSx and big ATI
$50,000: 427cid LPE TT

Don't forget the Stage I TTi kit is only $7,500 + Install (Figure $10K installed ).
