non intercooled maggie
Considerng buying a non intercooled MP112 maggie. It is presently on a running '99 vette. I also have a '99 so everything would be the same as far as the swap goes. My '99 has 18,000 miles on it. The used unit has approximately 20,000 miles on it. Owner of the maggie has none of the paperwork or the original Superchip Micro Tuner that came with the unit. He had all the work and install done by a tuner in his area. There is no one that does dyno tunes within a 100 miles of where I live. I will not be racing my corvette, just looking to make it a fun car with a bunch of extra torque. I am planning on doing my own install once he removes the unit from his car. Am I making a mistake purchasing a used non intercooled unit? pro and cons!

If you are getting it cheap enough, maggies are fun on street cars. A lot will depend on the price you are getting it for as far as smart or not. Also depends on what you want to use the car for, If you are happy with 500 or less rwhp then the maggie is a great choice. If you want big numbers you normally have to go centri. Also most likely you will have to trailer your car to a tuner after the install, if you don't have the factory software to go with your maggie.

IC is the way to go. If the price is right see how much it would cost to do an intercooler upgrade from magnuson, then go from there. These things heat soak on the IC models....can't imagine what the non IC models are like

Maggie prices are kinda high ( vs other options in the SC world). And Maggies aren't going to give you the highest HP numbers. Typically a maggie on a C5, with headers, properly tuned, will get you just up to 500-525 rwhp. The non-intercooled version isn't going to get you that high because you'll have to tune it down to allow for the higher IAT's. So look for something closer to 450 rwhp.
Now, 450 rwhp is nothing to sneer at. I'm just saying ... for the investment....
And please be careful. If you don't have a good tuner, and you don't have an intercooler, I'd be afraid you're going to break it. It's just too close to the edge.

non intercooled maggie
I have decided to pass on the non intercooled unit I was interested in purchasing. The owner of the maggie and I could not work out the deal. I wanted to physically see the maggie before purchase to check for stress cracks and other possible problems. He had family problems and we were not able to get together to meet.
Since this is only going to be street driven, I definitely want a maggie. I love the look, plus the instant low RPM power the maggie provides.
I am located about two hours from Carlisle, so maybe I will find something there.

I dig maggies too, but I would get the IC model. Like the previous comment said, you'll need a more conservative tune too avoid any detonation. You could always spray alky, but I've heard that its bad for the rotors. Like I said I love maggies, but if I had to choose between an a&a or a non IC maggie...I would take the a&a hands down. Heck a new a&a is only like 4k

What ever SC/TB you decide on you should give alot of thought
concerning the intercooler. Remember heat is your enemy.
There are many kinds of intercoolers find one that is effecient.
A good intercooler is as important as the blower it self.
Good luck.

The maggie you want will be fine using the 3.4 or 3.5 front wheel 5.5 to 6 pounds of boost. LS6 heads and a 220/230s/580/600 lift cam swap will get you over the 500whp mark and unless your going to track it most will be happy with that much torque/hp.
Without the heat exchanger I would stay at 6psi. After the heads and cam if you want more free HP, sharpen up your gear changing and move to 3.90 gears and MT tires. Nothing shabbie about a high 6 second 1/8th mile car. Once you get over 450whp you know your looking at clutch time just over the hill.. LOL
Decided early if you want a street car or a track car.
Street is neat but once you go track, its that never ending story.

you will be hard pressed to break 500rwhq below 7 psi even with ls6 heads and a cam otherwise I do not see any really bad information in this thread.
also do not think I would personaly go to 3.90 gears with a maggie

the maggie makes for a ton of fun on the street
The install is not that bad at all but here are some thing I would do at the same time:
1: install cam and replace Timming chain with upgrade while you have the steering rack out (oil pump is easy to get to also and it is a good time to upgrade to ported shimmed pump just be careful with the o-ring)
2. the stock harmonic dampener is a POS replace it with an IW overdrive unit A&A has them.
3. do the ECS ideler pully upgrade while you are in there or replace the ALT bracket with the later model.
4. think about doing a 8 rib setup (the IW overdrive can be had for same price as 8 rib)

I woul pass on the non-ic unless it was a really smoking deal, they are not bad just that the ic model is better and there are a lot around.

I have passed on the non intercooled maggie. Since this is only going to be street driven should I step up to a TVS2300 or will the MP122 maggie work for me.
I have already purchased the upgraded alternator bracket and will follow your other suggestions.
The car is an automatic with a 2:73 rear, I have picked up a 3:42 rear, but maybe a 3:15 will be a better choice. Have been thinking about purchasing a 2001 drive shaft which I have read is a stronger unit. Since the 3:42 was from a stick car will I have to change any thing to use it in my automatic car. While I am at it, I will probably do a 2800 stall convertor. I have also purchased the 1/4 inch heavy duty tunnel cover.
Any other help or suggestions will be greatly appreciated.

the mp112 or mp122 will work just fine. The TVS is a huge unit, and for a 5.7 is overkill. If you are sticking to 5-7 lbs of boost, the mp's are just fine. The TVS is a heck a of a lot more efficient, but at the end of the day, if you are only shooting for 500RWHP, they will all get you there just fine.

), and I had torque overkill with my maggie, I was always curious what a 2:73 would be like. I think I figured out that you could get to 60 in first gear with a 2:73 rear and a z06 trans....and with all the torque of the maggie, you might just get there in a hurry. Not to hijack the thread, but has anyone tried this?
