EVIL

i am looking into getting a supercharger and i've already decided i dont want the magneson, however i've narrowed it down to:

ati's procharger and vortech sq trim.

i know there are various intercooler combinations and different s/c head units, but i want to know what people think is the best of the two....i've heard good and bad about both and from my research personally i am leaning towards the vortech. any help is appreciated... - evil :reddevil

Call Andy, he has lots of experience with both.

I also live in Austin and have a procharger (I could help you out if you need some help during the install...).

I would go with the procharger again, since it so dam simple and pretty much has all the bugs worked out at this point. There are also quite a few procharged c5s in the 10s now. I'm not saying the vortech can't do it, just that the ATI kits are a little more proven.

i talked with leonard at auto-tek here in austin and he said the vortech is a better system. hmm...anyone else? evil :reddevil

The debate that never ends! :boxing

I chose ATI, but I'm sure Vortechs are good too. Get what you like, and don't worry about what anyone else thinks...

My tuner had both systems for me to choose from. He recomended the Vortech even thought the install was more involved for them, he said they are much more reliable and no S/C belt slippage as compared to the ATI. :cheers:

I'm not a guru on this but some people may want quietness and the Vortech SQ G-Trim on the ???standard LS1 system??? has the sleeper effect down pat. The upgraded T-Trims make some noticable whistling.

Air-air aftercooling (ATI) vs. air-water aftercooling (Vortech). In virtually all reasons imaginable, I'd favor air-water aftercooling. Two exceptions that would make me favor air-air aftercooling would be reliability (if your cooler water pump breaks, then your engine is in danger; my Vortech aftercooler water pump broke on my '95 T/A kit, may be resolved now) and possible advantages in road racing conditions (as long as you avoid prolonged drafting).

Isn't the vortech air-water-air ? Not just air-water. Water is used as a transfer medium only.

Vortech should be a bit quieter and more reliable with less belt issues.
ATI should have more peak power but more headaches, ie: radiator & many more potential belt problems.

ATI would be better for road racing than the Vortech if any SC should be used for roadracing for that matter.

brent eb02

the 2 ati cars i know of in the 10's had extensive" other" work done as well

were talkin heads cam built bottom ends

the other one has a 383 stoker HEADS CAM with an ati and NOS TOO !!!

so there is much much more to getting into the 10s with an ati...

SleepieAce

My ATI is plenty reliable. No belt slippage issues or anything else so far, just problems with traction. :D My tuner liked the ATI best, but I think that tuners develope preferences just like everyone else. You'll have to decide which system you like best and go for it. I personally went with the ATI because it made more h/p and didn't require drilling the oil pan, which makes it easier to return to stock if I ever decide to sell (which is not likely but never say never) :cheers:

Why is that? :confused:

hrm ... exactly how much longer is Vortech even going to be a player in the SC game though.

re: Why Vortech not good for road racing? The Air to Water cooler builds heat and loses efficiency after long use whereas the Air-To-Air Intercoolers don't suffer this continued use problem. Only would see this with road racing, not street driving.

tatooed:
Why you think Vortech is getting out of the SC biz?

QuickSilver2002

I did not mean to imply that you could bolt on a procharger and be in the 10s. Just saying that several have done it and more will follow. The Vortechs could do the same, but there are fewer hard core guys taking that path.

BTW, I think opticz06 just got into the 10s with a bolt on ATI car with forged pistons. http://forums.corvetteforum.com/zerothread?id=614763. He may have more, but I think he indicated that was it (he was not using the 30shot on this run).

molon labe

thats been the word on the streets for a few months now.

Devil Dog

Stick with the air to air intercoolers, they are more efficient,require less maintenance, and a lot more reliable (no pumps,no hoses,no need to add ice).

Bruce

can't go wrong with eitherone. But I would prefer ATI because it come with standard intercooler, where vortech is extra $.

The Air-Air intercooling is more efficient according to several studies that I read. Unfortunately, I no longer have the information because I made the decision quite a while ago. Another advantage of the ATI is that the oil is self-contained (NO tapping the oil pan).

ATI belt slippage? Not at 7psi. If you want to get into the 10's, I would follow OpticZ and get forged pistons, Lunati Rods, and ARP bolts. The parts aren't that expensive. . .don't know about the labor. By the way, we aren't talking barely into the 10's. If he pulls a decent 60' time, he will be running mid-10's easy. :thumbs: :cheers: :thumbs:

That's odd, I've never heard of those guys. I've been to plenty of corvette events around town and there name has never once come up.

Just found their website. http://www.autotekinc.com/ls1.shtml Wow, those prices look a little insane. 10k for a ls1 crate motor :eek:, I hope those prices are a misprint.
