Supercharge or not? I think I speak for most everyone out there with an F/I setup.... you definitely won't regret it... Procharger, Maggie, or TT.

As to Maggie vs Procharger. It's well documented the differences in these setups. Personally I love the low-end torque. Some may not put stock in torque, but that's what gets the car out of the hole and on it's way. As for spinning the tires, well it certainly does that. You could always seek to cure that with stickier tires - at your own peril. It would be one BEASTLY machine if it was hooking the tires down low.

On the subject of taking down a Z06. Keep in mind that peak numbers don't tell the whole story.

I did my best eyeballing at several different posted DYNO's to compare HP and TQ side-by-side. I couldn't find a Procharger dyno without any other mods (LOL), so this one represented Procharger with headers. The rest are as advertised. Hope this helps.

 

Thanks..You dont mention anything about maintenance or the weight added for each...

 

Turbo anyone? how does it compare? Not the twin 1000 hp type, but a single turbo system. Who makes them and what are the stats and price?

 

I don't know of any mass-produced single-turbo kits for the C6... I would assume that is because to make a single turbo capable of making the power/ power band equal to that of a twin setup would be: A) very large, and B) have more lag. A large single turbo would undoubtedly make more power, but it would be uber-laggy and boost would probably come on so violent that it wouldn't be as practical on the street...

 

I'm sure you realize this, but your car is lean spiking real bad up top, which is the reason the power goes up dramatically all at once... You could blow up your motor if you're not careful. Might want to get some more fuel in that thing above 6000 rpm...

In the Mustang world that dip before the lean spike is an indication of a pegged maf.

Chuck, thanks, I sent your comments to my mod shop and tuner.

 

If you need any help getting it right just let me know...

Good point and thanks for the comment. I do have another question for you if you don't mind. What if a person were only looking for 100 hp of so, would there still be the issues you spoke about? I am asking because I have watched the videos on the twin system and there appears to be so much power that the car has a difficult time planting especially when the boost hits. If you could get a system that provided a reasonable punch starting at about 3k and would peak somewhere in the 5k range it would seem to be a more managable curve. My concern about the roots style superchargers is the fact the boost is on almost from idle so I would be hitting my suspect rear with more torque than what is already hitting it. I am not real sure about the centrifugal type in regards to when the boost really starts to come on. I have a 2005 C6 and as I am sure you know there have been problems. All that power won't be any fun if all I do is break something. So I was just thinking the car has good torque now from idle, but a little push while in motion would be great.

 

A single turbo on a 6-8 cylinder car would be inefficient for what you are looking for, and are mainly used for drag racing and big HP numbers... Think about every factory turbocharged production car; the 4 cyl cars (VW's, Subaru’s, Mitsubishis, Mazda’s) have a single, small to medium sized turbo to provide good mid range power with minimal lag. 6 cyl and 8 cyl (Porsche, Audi, Toyota) use two turbos to achieve the same outcome.

For what you are looking for, I believe a centrifugal supercharger, or even the APS twin turbo kit set at lower boost will get you what you are looking for: 500 whp/500 wtq with decent tires is very street able.

 

Thanks Turbo, I appreciate the info....

 

Was there just before Carlisle.
Red paddle shift convertible turned 11.55s /122 mph.
Manual trans. Callaway SuperCharged Corvettes are quicker by over 1/2 sec., mainly due to differences in final drive ratio and driveline losses.

 

Excellent post. Very, very nice.

That does it for me. MAGNACHARGER.

Thank you all very much.

 

I did a procharger on my C6 Z51 and I love it. I added Kooks long tubes and Corsa Sport on the back end. I also added a Kenny Bell fuel boost (a must) and put zo6 tires and wheels on the car (more rubber to the ground). The great thing is the car needs no hood mods. I drive the car every day and race it on the autocross circut on the weekend. I have never had an overheating problem. I have sat is traffic in 90deg weather. No problems. The car runs like a dream and hauls a** Over 500 RWHP.

 

Enjoy! Looking forward to seeing your post when you have it finished.

I still have trouble keeping the ****-eatin grin off my face everytime I get in my car.

 

I'm also giving serious consideration to a supercharger, changing the hood is out of the question for me, so I would go Procharger. I'm hung up on how its going to decrease the life of the car. Its my first vette and I want to keep it for a long time. I also dont want something thats going to break down all the time, or prevent me from having a dealer that can service the car. HOw do dealerships generally react if a car comes in with a procharger? How long does the drivetrain hold up? Reliability is a serious must for me because the Vette is a toy for me, but I do drive it to work and back in the warm weather. I like to "get on it" occasionally on the highway (legal speeds of course ), and do some nice 0-60 runs. Im not into redline clutch drops, but I enjoy torque. What do you guys think, should I bite the bullet?? Does the car realy feel a lot different with a Procharger?? Sorry to hijak the thread, but figured my questions were related and might help others.

Thanks

 

I wouldn't worry too much about the drivetrain. Just put an upgraded clutch in and maybe upgrade the output shafts, then you'll be good to go. Unless you plan on going to the track with sticky tires, you'll probably never break any of the drivetrain parts.

As for the longevity of the car or keeping it for a long time, don't worry, the Procharger isn't going make your car require a burial ceremony, it might burn up the motor up if the tune up is way off, but nothing that can't be fixed. In fact, if it's done right the first time, you might not ever get to that point. A good tune will go a long way in motor longevity.

From what I've seen, cars we build in house leave and almost never come back with problems. That's because we do LS1's, LS2's, LS6's, and LS7's every day, so we know what it takes to do it right. It's the do it yourself cars, and the cars built by "my buddies a mechanic", that seem to carry all the problems. So be very picky about who you have do the work. Make sure it's not the first time they've put a Procharger on a Corvette. In fact, make sure it's not the first time they've worked on a Corvette. You do not want, "that guy", doing your work.

And I'm speaking statistically here, so I don't mean to offend. I know there are some good mechanics out there who haven't worked on a lot of LSx's, who can do work to them without messing them up. But I see this stuff every day, so you'd be suprised what some people tell me about the guys who did the work on their car. I have to ask because they come to us to fix all their problems. I'll take a picture of one that's at my shop right now. It will better define why I have the opinion I do about shadetree mechanics.

THanks Chuck for the info. Im looking forward to see those pictures of what can go wrong on a bad install. Thanks

 

To answer some of your questions, if you go to the dealer for warranty work, allot of dealers will not honor your warranty. I happen to be friends with my dealer and he will honor the warranty if it is not directly related to the procharger (ie: suspension or electrical). Reliability is pretty much the same if you don't continually abuse the car with repeated harsh luanches and redline shifting. The difference between a not procharged engine and procharged engine is night and day. The average C6 has 325-330RWHP and a procharged engine has 500+ RWHP. I suggest you put a fuel boost system on the car to reduce the chance of running the engine lean. Haven't had any problems with the Procharger on the car at all except I had to change the serpentine belt after a couple of thousand miles due to slipping.

 

And now for your viewing pleasure...

Words can not describe the thoughts that come to mind when I see things like this... Or maybe I should rephrase that.. The things that come to my mind would probably get me banned from this board.

So, I'm not going to publicize my thoughts. I'm just going to let you see, and you can decide for yourself why certain people shouldn't be allowed to work on your car.... Or even LOOK at it for that matter. lol
