So i uninstalled my maggie last night and shipped her to magnuson this morning. This was my 2nd removal of her, and even the neighbors are starting to ask me if my girlfriend gets lonely because im in the garage so much. So since i had her open i just kept going. Full uninstall. I messed something up at the track and need to take her off for warranty purposes... I dont think she's going back in though. David at magnuson put a new carbon fiber jackshaft on a month or two ago and i guess somehow it was too short? He's going to resolve that issue and pack on some brand new bearings as well and check out the whole system. So when she gets back in a week or so she's going on the auction block. Other than sparking some interest for potential buyer, im really wondering what a fair price would be.
Is $4,300 shipped reasonable? Should i ask more/less? It'll be in brand new condition once it gets back from magnuson, ill prob leave it in their packaging.. Its been updated to the latest design/version, i'll through in the boost and a/f gauges and the ashtray gauge pod, the vette FRC's, 2.8" and 2.6" pulleys, 2 working magnavolts (1 is brand new), the 2 month old intercooler, belt tensioner, drill kit, ummm everything needed, a full kit plus some. I'll get the crank pins, windshield wiper spacer, and fuse tap from David when he sends it back. I'll label and package everything nicely since i know how difficult it can be to sort through. I'm hooked on this going to the track thing and plan to use the money from the maggie to upgrade suspension and likely a UUC flywheel. Would a lighter flywheel be good or bad for the track? Thanks for all suggestions/opinions!

Whaddya think got messed up at the track? Did it have anything to do with the maggie? Gotta ask why you would opt for not re-installing the Maggie, and count me as interested in buying it potentially (depending on your answers to prior questions and $$)

+maybe this is first interest in Maggie, might count for somthing:bouncy:

++ and lighter flywheel should be all around good . . .

id be interested in the kit if you do indeed decide to sell, although i would like to see if you could talk Magnuson into converting the front inlet to fit an LS2 while it was there since thats what i have,,

feel free to email me if your gonna sell, maybe work something out while its still at Mag.

Well i can guarantee you i'll be 100% honest with you about this. I was driving her hard, really high rpms all day. Engine power reduced light came on went off, came on etc.. StealthV somehow knew if i changed the throttle body that'd go away. I tried it and it did. I was driving it and i could feel hesitation and if i want the warranty to look at it, i can't have a maggie on there. I would say most of my frustration is the hell i went through getting the used maggie with damaged/missing parts. So i had to shell out cash for a new intercooler and thought i needed a new magnavolt but the old was still working, so there are 2. Then i finally get it all installed and drive it for a week, post a noise online, turns out the bearings were bad when i received it. So i had to pull the main blower off, not too difficult, ship it to Cali to find out it's the old design. To update the design and get new jackshaft and bearings was over $800, plus the car had to sit for about 8 days waiting for maggie to return. Then i get it back and the belt is squeaking because magnuson didnt have the two pulleys aligned which is what is being fixed now. I've just gone through a lot of install/uninstall. Then the week it took me to make the gauge pod and install the gauges... I've just spent a crazy amount of time and $$ on the car in the last 3-4 months and ive only owned the car since December.

So im selling basically exactly what i wish i would have bought. A used maggie with the manufactures reassurance that it is 100% updated and in working condition. I am not sure what caused the problems with the car yet. Plan is to get it back to stock this week and see if the issue is still there. Then we can blame it on maggie on not. Either way even if it was her fault David will make sure she is 100% before sending it back to me. The engine shop at the track said naturally aspirated engines are better for the track. Im sure this could be an interesting discussion on here, but i can definitely see their point especially on a shorter track where you're constantly changing RPMs. As for day to day M5 killing on the highway, its great! And when driving normal i actually saw an increase in MPG.

I'm not sure if they can do that or how much it'd cost, but i dont want to pay for that conversion! I took her to the custom shipping place this morning, so she should get to Ventura Thurs/Friday... If they can do it and you want to pay whatever they'll charge then i'd be fine with that

Exactly why I prefer "all-motor" setups (no N20, no boost). Fewer possibilities when trying to track down a problem, and no "band-aids" keeping things running (Magnavolts, water/alky injection, etc).

No disrespect to the FI crowd (and I'm definitely not trying to dissuade potential buyers of your kit, KMajecki), but for $5,000 you could put a killer head/cam/intake package on an LS motor and not only hang with the boosted guys, but still be driving around while they're trying to figure out problems with jackshafts, Magnavolts, relays, wiring, hoses, belts.......

All motor all the way, baby. :thumbsup:

That is true, but there's still the wow factor when you tell people you have a supercharged corvette engine, plus the whine is something that cant be beat. For people not planning on tracking their car often i think the maggie is a great plan. Engine shop at the track said for $6-7,000k i could have my engine bored and stroked to a 403, although most on here say a 408, whats 5 cubic inches? Either way that's the plan. Turn her into a 403(8) stroker and get headers. Like everything else, there are pros and cons to force induction. I really liked it when it was on, i just dont see myself installing my stock stuff, then uninstalling stock to reinstall the maggie. Just too much time and work. I'd rather drop it off at an engine shop for a while and let them screw with it. I appreciate your opinion and also hope this doesnt deter any potential buyers. Just as Chef went from the supercharger to a bigger engine, i too am seeking "the next step up".

Exactly right. Having owned two (aftermarket) supercharged cars, it is definitely fun to watch the boost gauge peg, plus the "ooooh ahhhh" factor when you pop the hood for people.

You guys will have to give some heads up the next time you plan on going to the track. I can always do some vid taping and take stills of ya'll running the track. :)

No used internals for sure here. Im thinking of getting used headers though, any dangers with that? Do stroked engines sound bad/good/any different than stock? Only difference is the cylinder is bored slightly and the crank extends piston travel creating a larger cylinder right? I would think a larger cylinder might sound deeper?

I absolutely agree that the all-motor setups are often better in many ways than FI motors. However, when smog is an issue, like it is out here in CA, FI becomes a terrific solution to added power.

Basically, if one wants to "sniff" 500rwhp and still be CA smog compliant, you have to goto FI or go probably an LS-7.

Any other suggestions and I'm all ears... :)

I just went to hear my baby today. I've waited for over two months to hear her voice. I was all ready on Saturday to hit the dyno and see what she can do at wot but instead she was hungry and ate the slave cylinder & rubber and the clutch hit the floor and remains there.

Today I just fired her up and holy shiat!...meanwhile the power went off in the shop so the lift can't go back up and then in walks the delivery man with the slave kit in hand...Tonight she'll be ready with a fairly rich tune for these hot as hell summer months so I'll most likely be down around 20 to the wheel for now but whoa!

The sounds shook the building and customers came in around looking for the car - they were looking at all the heavily modded vettes until one said....it's a god damn caddy!:worship:

Chef out...

Good advice there ^
Probably the best way to go in most cases.

However, his LS6 needs to be fixed anyways so why not just rework it?
