All opinions will be greatly appreiated. wich super charger would be the best for a stock C5 as hp, price, and wear and tear on the motor. I heard the new ATI p1sc is a very nice setup, and I like the fact that it is self contained no drilling into the oilpan. I have the cash and would greatly appreiate any info. ps I will buy from the vender who can help. thanks again... :D

 

VERTVETTE,

The PTC and Carroll kits are the only proven packages at this time with the PTC making more power for the most part and a more efficient intercooler system. Carroll buys some components from PTC.

The ATI and Magnuson's are yet to be proven on real world Vettes to me. But the ATI looks promising with the intercooler, though I don't like the idea of the same belt driving the SC as well as the water pump, alternator & power steering pump. This will limit potential output unless a better drive is used. They are claiming 535BHP which comes to about 450RWHP I believe in an M6, but I would like to see a few non-ATI installed cars out and what numbers they put down, as well as driveabilty, before advertising those numbers.

The Magnuson will be limited due to no intercooler and already needs a taller hood for clearance. You can run only so much boost on a 10.1-1 engine without intercooling. it was mentioned that an intercooler was in the works, but a pre-cooler will be pretty much ineffective and a cooler between the SC and intake will raise the hood that much more.

Maybe down the road as a few get out it will be a different story and a good option. Time will tell.

You can call me or even come by the shop to discuss this. Breathless is supposed to be a dealer now as well as ARE for the ATI and Nate at Xtreme is working with Magnuson. I deal with the PTC now and ATI if it pans out as well as a side project :cool:

Later,

Mike

 

The first response to this post makes some very good points from someone who many say is one of the bEST IN THE BUSINESS.

So now would be a good time for me to say that I always try to tell it like it is even though it may be at the risk of offending someone (in this case Mike Norris - Forgive me in advance Mike) and even though I genuinely don't mean to offend anyone. But I feel that part of our responsibilty as Corvette owners on this forum is to do our best to enlighten other owners with other possibilities and options so that they can make a wise decision.

When opinions, or even facts, are stated about a product that might deter one from one purchasing that product, I always ask myself, "Is the Tuner selling a competitive product?"

Unarguably, Mike himself answers this question . With that said, PTC uses the VORTEC if I'm not mistaken with perf modifications and customization so that it will actually fit the C5. The perf modifications themselves have resulted into an excellent product that Geoff at PTC has done some fantastic work with from what I hear. In fact, I haven't heard anything negative about it with the exception that at the begining there were some pulley issues. But GEOFF conquered that learning curve and any remaining issues have been resolved. Like Mike says, it definitely has been proven as has the CarrolSupercharger, very similar to PTC's because Carrol (In New Jersey) also uses the VORTEC but does not invole the perf modifcation that Geoff has made and therefore, is not as powerfull. Bu essentilyy they are both good prducts and somewhat prove. But both also cost somewhere in the neighborhood of $11K-$12K.

Whereas Mike makes a good point that the ATI C5 kit is unproven, the main componetry has been used on f-body's (Just like, you guessed it, the VORTEC) for a few years (If I'm wrong Mike, please tell me) Hence, instinct would tell me that the PROCHARGER wouldn't be a risky investment at all. But thats logic and not technical expertise which I have none of. Let me repeat, technical expertise - i have none of.

With that said, the only thing you can do regarding the PROCHARGER is start asking questions, like I did, on the various F-Body forums (www.ls1.com, http://www.ls1forum.com and there are many others). These are the owners who have much experience with PROCHARGER SC Technology, the same SC technology designed for the C5 (with the only diff being the Make-It-fit KIT itself), technology which has indeed been proven with thousands of them out there I'm sure.

Also, its important to know how reputable a manufacturer (ATI) is and how it treats its customers and resolves problems - thats just as important as the product itself. So far, I've heard only one case from the owner himself who feels ATI screwed him over really bad on his Mustang SC.

As far as the Magnuson, there are just too many Concerns with that product (and where they are going with it) at the moment for me as an owner to invest in - just my opinion on the Magnuson.

It is nice, however, that C5 owners finally have options besides Nitrous and Radical engine work. Don't forget about ARE's TT for $12,500 (which is almost done ... I think, ) or even LPE's TT, which also has been proven and has been drastically (heee ... heee) reduced from $22,995 to only $19,995 (MN6) (excluding shipping of course).

Good luck.

 

Thank you both for the info :seeya

 

We all now that LPE is not cheap,however remember there 20k package puts out the most linear 550 bhp you can experience in a C-5 all at a whopping 5 Lbs. of BOOST.After your warranty is up ,those Turbos have the capacity for there size for 13+Lbs. of boost.At 8Lbs. I would guess 630 bhp and I would hope and pray it all holds together,which IMHO I believe it can.In the worst case situation have the motor pulled ,do a bullet proof bottom end reconect the Turbos (oh you would be lowering it down to about 8:1 CR.)send it back to LPE and let them add adjustable boost and tune your car it in my best guess to have your car tune to about 775bhp-825 and your Max. Boostwould be about 13Lbs. I bet it would be 3-5000.00 for the testing tuning and install of the adjustable boost,and you can be sure before a Hi-Power pup leaves Lingenfelter will make sure he finds many **** defects that most tuners not most(Sorry) Some may not see,feel,smell or hear.
So with enough thought you may find a less expensive way to own what I believe to be certainly amongst the rarest but more important amongst the most fun C-5's $$$$ can buy and it can be done on a budget if you're creative enough.OH check the LPE website they have a used car section sometimes who knows???? you may HAMMER home a bargain.To all my fellow forced air induction fans HAPPY NEW YEAR!!

Ha-Ha,

The ATI works very well on the F-bods, even in higher boost configurations and both LT1 and LS1(so far). The ATI SC unit and the intercooler are proven for sure, but the drive is the ??? here.

The difference between the F-bodies and the Vettes are the drive system which is where I have some questions and/or concerns. The F-bodies have an independent drive that can have its own size (width) and tension to vary with boost levels and does not over stress the bearings of the alt, p/s and w/p. The Vette setup looks like it depends on the same belt as the accessories thereby limiting boost levels to a point and there may also be more stress on the water pump, power steering pump and alternator when making this belt have more tension to obtain higher boost levels.

Like I said before, maybe all will play out well and no drive problems. This will turn out to be good option if it does. Time will tell.

Yes, both PTC and Carroll use Vortech SC Head Units. ATI has thier own unit and is self contained and requires oil change intervals if I remember correctly. I have yet to hear an iron clad price on the ARE TT, but it should be close to what you quoted. The LPE 550 is a very good deal compared to the old Stage 1 seeing as the cut the price $3K and added heads and cam to it where it wasn't there before.

Hope this helps.

Mike
