Maggie gang - need input from your experience
I will be sending car to Lingenfelter in couple months. I know I will be doing a maggie and 3 gauge set up.
I am waivering on a couple things.
I have LG longtubes already on with hf cats - bullets to boot, so my neighbors appreciate me
My plans are to run with the maggie for at least a year or more. Perhaps when I get bored, I will forge the bottom. As it stands now, I need to learn to use the ~500 rwhp.
1) Should I go with the 112 or 122? I know wth stock bottom and normal set up I will see increase in hp, but nothing in torque. Perhaps with the headers I may see both hp and tq... anyone have a clue?
2) I know I will lose some boost with the headers. Should I just go with the smaller pulley from the start? I know it voids the maggie warantee, but will the wear be so much that the maggie will wear out that much quicker??
What would you guys do??
Thanks

I have headers as welll and I would suggest You put a smaller pulley from the start!!
I would also go with the 112 because it'll get You 500 or more RWHP and will cost less money.
Good luck!

Have LPE put a cam in it at the same time. Now is the time it will save you in the long run on labor. I went with the 122 and the LPE cold air intake with the 100maf and a comp cam. If you plan on doing a forged bottom end later go with the 122 to get more air at lower iat and if you are doing a bottom end you will want to go to a 403ci. I live in Fl. and the 122 was used to keep intake air temps at a lower level. If you do a cam and headers start out with a 3.2 pulley to get 7.5lbs of boost or try a 3.0. The 122 comes with a 3.6 pulley.

If I was doing it all over again (and the M122 was available at the time), I probably would have went this route.

I've had my 112 Maggie for almost 2 months now and all I can say is your gonna LOVE IT! Sometimes I forget I even have one under the hood until I hit the throttle.......just to check if it's still working. 
Mine dyno'ed at 502 rwhp w/ Kook's 1 7/8", hi-flo cats, Route 66's, LPE's Maggie CIA and a Reichard 3.2 dia. pulley thanks to 1bdasvt, (thanks George!). That's about it, stock motor & cam so I was shocked at the dyno results.
I've had no belt issues.....yet. My idle is set kind'a high (900 rpm vs. 650 rpm prior to install). I need to get that re-adjusted and I purchased a KB boost-a-pump to replace the Magnavolt sometime in the near future.
At this point, I wish I had a cam.....that's what's missing. Not so much for the additional HP, but just to hear it at idle! But first I need new rear tires.....so get ready brother!!!!

Hey George! and everyone. It's been raining everyday here in Houston for what seem like month. I hit a patch of water yesterday on the freeway and felt the back end "drift" for a second 
. I have to get some new tires (rears) soon thanks to the s/c.....or is the pulley?? 
Anyway'z .....the boost-a-pump issue. Man, I don't know what to do now that I purchased the KB BAP. LPE does install them, replacing the Magnavolt. I figure their the pro's and must have a good reason for doing so, perhaps for reliablity and warranty?
But on the flip side, George and others have been told, the current Magnavolt provided with the kit is new and improved so don't waste your money on the KB BAP. (but it's so cool look'in!
) The feedback has been 50/50. All I know is, I still feel a "lag" or hesitation sometimes when hit full throttle. Seems like a fuel issue....could it be the Magnavolt?? Who knows, I have to take it back to address the idle issue anyway.
If someone with LPE could chime in, that would be helpful.

I don't have any hesitation when hitting the throttle. Might be the pump, then again - if George is right - it could be torque mgt. I did ask LPE to reduce/eliminate as much torque mgt as possible in mine - so fortunately I don't have that issue... but I'm certainly not the expert on that.
There's a member from my local club that occasionally shows up at the weekly cruise-in and he just got his car back from LPE with a Maggie setup. His Maggie is the M112 model as well, but it did vary somewhat from mine (different inlet angle and some Magnacharger badges - made it look like a M122). It's definitely a newer model (hmm - odd) and likely would be using the newer pump George referred to. If he shows up this week, I'll get a peek and let you know if it has the newer pump or if it's the KB.

Sage advice....If it were me and I were strongly considering forging the motor later, I'd go with the 122.
Thing is, I'm happy with what I have and truth be told can't utilize all it's power properly.

If you are going to stick with the stock bottom end.....I would not spend the extra money on the 122. If you're going to build a forged motor and turn the boost up, you need the 122. I would go ahead and go with the 3.2" pulley...(if you go with a 112) ...it will make up for the boost loss from the headers. You will be around 6 lbs with the 3.2.......I have not had any problems with the maggie 112 with a 3.2. You will love the package and LPEs install (I think LPE is still installing the KB Boost-a Pump...they did on mine).
BTW: get the fuel rail covers.

Not sure why you'd even consider the 112 when the 122 is like $400 more. 500 seems like a lot and it is, but you'll want more trust me. Plus you lose boost with the long tubes, you're going to need it imho.
