What Super Charger Kits can be put on an LT1 and not affect its reliabilty, I think 8 PSI is max what do u guys think?
Here are some kits i was thinking about

ProCharger P600B Kit w/ 2-Core Intercooler (if i upgraded to the P1SC H.O. would that bring up PSI? or is it just a better unit then the P600B - $3,099

Vortech Supercharger Kit with V-1 S-Trim - $3,399

Vortech Supercharger Kit w/ V-2 SQ S-Trim - $3,399
What is the difference between the two Vortech Systems?

 

You should search this topic. Boost and high compression is not safe. A piston will go. If your ready for a rebuild go for it. 600b is worthless IMO, and both vortech kits are quality(no intercooler). You need to give some more info on what your looking for, and how much $$$$$$ your willing to spend. There is a lot more than just the kit to buy.

one is an SQ...

SQ = Super Quiet

the s-trim is quite a loud blower

 

p600b is worthless thats what I have I went from a 13.7 @ 102 to a 12.26@ 115 with just the blower once I put gears and a stall in my car ill see 11s for sure on a stock motor, the blower has been on for two years now and no problems with it, I just wish my trans and rear could take as much abuse as the motor is.

 

The P600B is not worthless my friend. I have had mine on since 1995 and it is still running strong. It is a bit loud, like the s-trim.

The kit to get would be the P1SC with the twin intercoolers. The twins fit real nice. The vortech is really good too, but I never cared for their water to air intercooler.

You can run the blower without doing anything to the shortblock, but it will break eventually, the LT1 pistons/rings were never designed for forced induction. The factory would have put forged pistons in and probably a forged crank if their was a blower on this engine.

 

Here's the deal- don't let anyone fool ya, it's lack of tuning and greed that kill an LT1. With the right tuning, and common sense, 6psi can last forever.

I make 11 second power, with a 12 second chassis. One more part (torque converter) and I will be in the 11's on 6psi w/ a 100% stock motor and my P1. I have a low 12 second car RIGHT NOW. All it took was the right parts and a good blower.

Get the P1. It made me at least 170rwhp more, and is bigger than the s-trim, not to mention intercooled.

To make it live? Easy-
1. Ditch the FMU for a 36# injector
2. Get to a dyno and tune it with a wide band with someone that actually has the experience.

 

If you are going to run the blower on a stock bottom end I would make sure you can afford to do a rebuilt (both with regards to money and downtime) - sure, it may last awhile with good tuning, etc. - but then again it may not. It isn't something I would want to gamble on.

As for which to get, my personal preference would be for a vortech kit and add a spearco intercooler.

the biggest thing you have to watch for is knock that will kill a motor, I use a scan tool to watch for any on my car, im still on stock programing sence I have a 93 its really hard to get someone to work with you on a chip, I have PCM for less on my side now I just have to get off my butt and get a data log off datamaster for them of my car now and send it to them and work from there. im hoping for a mid 11 second pass next year once I get gears/stall and some programing I should easily see that sence right now my car is a dog off the line only 2.0 60 foots.

 

These engines were (obviously) not designed for boost. As has been mentioned, the pistons are the weak point. I would NOT assume 6lbs is "safe", but it's a lot safer than it would be with more boost.

The thing is, 6lbs doesn't really net much hp on an LT1. Obviously, if you also have good heads, a big cam, etc. it will make good power. But most people interested in "just" 6lbs of boost want a bolt-on situation. These typically don't gain more than 75rwhp or a bit more with 6psi. A good exhaust system really helps out a boosted car, BTW. Add headers and a good cat back and you will gain an additonal 30-40rwhp. But if you think your car is gonna be the hottest thing in the neighborhood with just a 6psi blower, think again! 6lbs of boost on an LS1 is another matter, those things rock with a little boost.

Bottom line, if you are interested in "reliability", you really shouldn't boost a stock short block. You might get lucky, but no matter what you are not going to achieve OEM engine longevity.

Both kits have its advantages. Procharger with the intercooler and vortec with a little better quality. Its all a matter of personal preference.

Worthless might be your opinion but how many of those s-trims put out 500+rwhp and run almost 130mph in the 1/4.

 

I think the Vortech units are much nicer than the 600b. If I had to do it over again, I might decide on the P1-SC since you don't have to punch a hole in the oil pan for a return line. Oh well, I'm getting ready to send my V1 back to Vortech and have em make a V2 out of it with the quieter impeller. A v1 sounds cool as all get out when it's making boost, but at idle it wails like a banshee. If you're going to invest in the supercharger, go ahead and get bigger injectors (dump the FMU), a better intake pump (the Trex is annoying after about 30 seconds), 160 t-stat, colder plugs, and some good programming (OBD1 conversion if possible). And yes, 6 lbs will wake your car up big time, how many other things can you do to gain 80-100 rwhp without refilling a bottle every week? Plus, the blower will grow with you, build a better engine, turn up the boost. Oh yeah, if you go over 6 lbs, get ready to rebuild the motor, the auto tranny or clutch if it's a 6 speed, and be ready for the rearend to explode. But other than that, enjoy
