For those who may have a few grand burning a hole in their pocket.

Tempting, but you should consider a 408-427 CID stroker followed by a TVS2300, 4.0L Whipple (my choice), or some kind of custom turbo build. Unless 500 RWHP/475 RWTQ is enough for you.

 

Good starting price. Nothing beats a stock motor and a positive displacement supercharger. I have had much faster cars, turbos, prochargers, and big cubes. Nothing is more fun to drive over that.

 

Damn, if only I wasn't getting married next year. Man would the fiancee be pissed if all of a sudden a few $k was missing from the account and a shiny Maggie was on the doorstep haha

 

So...the Maggie's for the V1, GTO, and Corvette are three very different setups. Which one is this actually for?

 

The description says it is off the V. I think just the intake kits, mounting stuff, and hoses are different right? I dunno, that's just what I have gathered, I'm probably wrong though.

 

Soooo tempting....

 

its pretty much the same setup on all the different cars..the vette and V share the same accesories spacing..gto i believe uses a different front bracket and longer or shorter jack shaft but im not certain which.

cancer(member here) can give you details on whats different as he used a 122 from a gto on his V

 

Pulley spacing is different on the GTO, will not match with the V or Vette. The supercharger (rotor housing) is placed further towards the front of the motor on the intake on the Vette version, so the hood will not close if the Vette unit is installed on a V.

Consequently, the V rotor housing is too far back on the intake for the Vette hood to close. These things are not one size fits all.

JCC installed the GTO 122 head unit on his existing V Maggie intake. That's how the pulleys lined up.

 

If I had a couple grand sitting around I would jump on this... seems to be a pretty slick deal

 

Oh yeah!



Wanna do some serious racing? Then go all out, find another "kit" (Procharger, turbo, Whipple, etc), and have at it. Mod Hell isn't for everyone, though.

I say, criticize it all you want. A maggie might not quite reach that 500 rwhp threshold without doing some additional work, but it's a straight forward install, it's reversible, and it makes street driving so-o much more fun.

 

Agreed... A Maggie is great for a street car. If your a serious racer and all that then you'll want something else but really who buys one of these cars as a "drag car"? (Don't get me wrong or take that outta text as I too have been pushing the envelope and will go bigger) but the reliability and simplicity says it all.

 

Sounds like the kind of pocket change we've all got lying around!

Seems pretty dumb for whoever bought this!

 

^^^...Ya why consider this maggie for 2 grand when you could just spend 15k on a tvs2300 stroker? lol.....

 

The dollar / performance on a real, forged LS3/LSX with twin turbo or Whipple is much better than a Maggie. Consider:

• $3000 for a used Maggie will net you +70 RWTQ, if you're unwilling to drop a couple thousand dollars on engine mods to support the blower. $3000/70 RWTQ = $42.86/RWTQ. Plus you're on borrowed time on both the motor and the blower.
  
• $16000 for a forged 416 CID LS3, 4.0L Whipple, and fuel system will do 950-1000 RWTQ (+600 RWTQ). $16000/600 RWTQ = $26.67/RWTQ.

 

I see the price per tq ratio but what about another 4-7k on an 8.8 or 9 inch and let's ballpark 2k for transmission upgrades to hold the power.. where is that cost ratio now? We're looking at 22k plus once you figure in what you'll need to upgrade to handle that kind of tq/hp. If money was no object, hell yes...but it usually is.

 

Because of the near-vertical torque curve, that's also recommended for the Maggie. So it evens out.

Even if you don't buy that argument, a CTS-V Magnum T-56 is $3295 after the core swap and it looks like the 54inches/GulfM3 DIY 8.8" will cost about $4700 if you buy the best of everything (e.g. carbon fiber driveshaft). So then you're up to $23000/600 RWTQ = $38.33 / RWTQ. But again, I'm going to argue that that's a totally unfair comparison. And while we're talking about unfair, I doubt you'll get the Maggie for $3000. I was generous to the Maggie in the original comparison.

 

There's no question the setup you are getting at is most favorable, just more expensive. You know you can get away with a maggie without trans upgrades and a ford rear but that's pushing it for sure. When do you (or anyone) justify that kind of cash versus just going v2? That's the question I ask myself when I consider big money upgrades to the v1.

 

Because the stock CTS-V, which weighs 400 lbs more than our car, only makes about 450 RWHP and RWTQ stock (blue line below). So while you can do a 2.55" pulley and a tune fairly cheaply (red line below), you'll have to do most of the same modifications (engine swap, bigger blower) to start making real power. So what you're really buying is the look of the car, inside and outside, for about $40,000 used.

 

Some would argue that 534hp at the wheels is real power but ya I can see the point. There's a point where all that extra hp just becomes completely unusable but I'd love to find out first hand where that point is lol.
