So what's the scoop on putting on the Maggie? From what I've read, it's a matter of very difficult fabrication even by forced induction shops. Is that right?

Installing a Magna on an f-body would be relatively simple. Yes, the cowl has to be notched, but it isn't that big of a deal. You can do that with an air tool with a cutting disk on it. They already make the kits with the correct LS1 f-body style pulley offset, they have had those for at least two years now.

Basically, the only 'fab' work you would need to do is to create your own intake piping to connect a MAF and filter too. Pretty simple with 3.75" tubing.

The problem? Most guys are lazy, and want things easy. But these same guys will spend months fabbing up a custom turbo kit that doesn't fit well. I bet I could have a Magna running in an f-body in two days tops.

A few pics of member's cars that have done it here:

Also, it's too small... We need something bigger.

Give me the small one. I like that torque curve even at something "low" like 480-500hp.

I know it would add extra cost...

But couldnt any F-Body guys who want a twin screw, just buy the vette kit, and switch too Corvette accessory drive and parts ??

Is there any reason the PAS/Alternator brackets etc couldnt be used on an F-Body ? to allow the fitment of a KB ?

Then adapt any other bits as needed.

If you are talking about maggies in particular please elaborate... if it was i'm sure they were spinning the **** out of it (6000 rpm) a lot or something wasn't right. I've seen some scarry stuff happen with "Old School" roots blowers on Gen I chevy's or big blocks but I have yet to see a maggie or OEM type roots blower explode like that.

I've heard of turbos falling apart, too... How common is it that we're talking about here? Because it couldn't be too common considering Ford has ventured on equipping at least two mass-produced vehicles already, GM at least one mass-produced vehicle, with this type of supercharger while enduring countless recalls year after year for things like cruise control switches lighting cars on fire...

Maybe they're really not much to worry about.

Place these two words in a google search: "nitrous" and "explosion"

People still equip nitrous systems in their cars, don't they?

I am real close to going with a Maggie on my C5. Easy to bump it up to 10 or 12 lbs of boost if you need it. (more also) My motor is a forged 427 so it could be fun.

From what I was told, 20 hp per pound of boost. More on a modded motor like mine.

Lets see,,, If I have 500 hp at the rear wheels now and add 10-12 lbs of boost,,,,,

Very cool..

Is the Maggie capable of feeding a 427 ??

Boost is boost isnt it? Guess we will find out? Even if I lose some HP, how much can you REALLY use? You will not hook up with 600 hp on the street. I've got 509rwhp plus a 150 wet kit. Traction is a joke.

Worst case is I end up around 650 -700 with 12 lb of boost and look good..

Just tired of filling bottles. Especially since there is none in my area..

Boost is boost? Have you seen the different torque curves of the different blower types?

Boost is defo not just Boost.

Besides, Its airflow you want ! Of course, a nice side effect of huge airflow is boost.

I should have no need to wind this thing much past 6000-6200. Maggies or Roots type blowers build HP earlier. I realize others continue building hp much higher.

Big HP at 7000 rpm is ok for a race motor. Not that usable for a daily driver IMHO.

In all honesty, there are still some things for me to check out.. One thing I do know,, We put a Vortech on my buddies Z06. He abolutely loves it.. The whine drives me a tad over the edge!!

Hah, there are actually some people out there that will say, "Yeah, you will just blow the tires loose with THAT..."

When did having area under the curve go out of style? I swear...

THIS is ideal for a street motor, man... Half throttle between 2k and 2.5k rpms to put you in your seat a little without having to go 6k rpms and scaring the **** out the intersection... That's STREET!

We need this thing man... Well, you guys need it. I can't give up my turbo.
