I've recently purchased a Procharger V1 Kit and installed it on my 2000 C5 Corvette, my car is absolutely stock, so of course high compression pistons. Took it to a few tuning workshops and all I get is that the Procharger with stock boost would at least smash up my block because there are no modifications on the block. So, I've got a few advices from different tuning garages and few of them are either changing the whole block to forged pistons, connector rods, crankshaft, etc. from Ross, Crower, etc. or to give the pistons as much rich petrol as it can for example upgrading the fuel pump, injectors, installing a regulator, etc. in order to stop the pistons from actually breaking. The third advice I got is to install a bigger size Pulley and belt in order to reduce the boost produced on a pull. I'm quite new to Prochargers so your help would be appreciated and any questions are welcome.
Thank you in advance for reading,

Hello, I would add a Alky control kit and keep your boost under 10 psi an of course a good tune and call it good. No need to replace anything if it is not broke but I'm the one to talk
What pulley size do you have?? It must be small so they are concerned about the potential boost that you will get. I have a Stage II kit with 4.38" pulley and am generating 7.5 psi boost. If you stay under 8-9 psi you should be fine. You can go with a smaller pulley (larger boost) but will need a meth kit.
You DON'T need a rebuilt engine. Mine is completely stock. I suggest that you find a shop that specializes in LS engines with superchargers.
Brandon .. I have no idea about an Alky Control Kit.. may you explain please?
01vetter I'm not quite sure but this Pulley generates around 9psi currently. So, the smaller the pulley is the more boost generated and the larger the pulley is the less boost generated right? so if I buy a larger pulley and install it then see how much PSI it goes.. and goes up to 7PSI then no need to change anything in the engine at all?

I'll do my best but this is a system which progressively adds methanol into your intake tube/charge pipe to cool your cylinder. It's basically a liquid intercooler They make complete kits ready to install.
How much boost will the kit make? A stock LS1 (in good condition of corse) should be able to manage ~8psi safely. You could install a BOV that will limit the boost to a safe level. Running extra fuel through the injectors will keep the pistons cooler and will help avoid detonation. A rich fuel mixture is common on nitrous cars but this isn't an ideal solution for a daily driven supercharger car because it robs power, uses more fuel, fouls spark plugs and can clog the cats. A good intercooler will help prevent detonation without the other negative effects. Rebulding the block with forged components will allow you to run much more boost and thus allow you to make more hp but will cost lots of money. Lowering the engines static compression will allow you to run more boost without breaking the bank. You can do this by getting a set of heads with a bigger combustion chambers or modify the stockers. You can also get a thicker set of head gaskets.
Brandon thanks for the suggestion but I think I'll go with what 01vetter says.
Sharkbiteattack I think I'll go for what 01vetter says, the kit makes about ~9-10psi right now, it's the biggest procharger available.. about 88mm I think. What I'll do is wait for what 01vetter says about pulley sizes and yes I have an HKS SSQV BOV installed into the pipe between the intake and the intercooler and still gives me about 10 psi per pull and we only pulled it once to avoid any block problems and since the car's ECU still not programmed yet.
Mainly because I'm looking for anything just to at least drive the car once. Yet, I paid loads and hell loads of money just to make the Supercharger fit properly and everything fitted properly. I'll wait for 01vetter to give me a reply and we'll see.

Hope this helps
BOV's/BPV's do not limit boost, simply hold pressure and releases it. This isn't turbo land where you would have a MBC or EBC to the Turbo wastegates to limit boost pressure. There are different BOV springs or settings which would make a valve harder to open to take the increase in pressure... Then there are the what I call the side shot valves where the pressure is perpendicular to the piston or diaphragm opening not pushing against it so it has a faster opening reaction time. The real only way to limit pressure on a SC is go up in pulley size or restrictor plate.
Definitely don't need to replace anything, yet. The tune will be critical in making your stock parts last. I ran 6lbs with no meth for a while with just headers so it can be done!

Listening to 01Vetter and staying conservative on boost is not a bad idea, but if you keep running that car on a stock tune, you are going to need to rebuild your motor sooner rather than later. It can happen in one boosted pull. These motors in stock form won't put up with many mistakes while under boost.
Tune the car conservatively first by setting it up rich and low on ignition timing, then add boost and then make the tune more aggressive if you choose, but stay out of boost on that stock tune unless you don't mind spending a bunch of money and letting the car sit while it gets fixed. I am guessing it is not so easy or cheap to get parts and work done over there.
Thanks for the replies. Yeah, We're gonna get a bigger pulley and try it out and the problem when we pulled it for the first time there were like fuel cuts and the problem was because the temperature sensor that goes between the intake and the intercooler pipe wasnt installed.. we'll install it, try a bigger pulley and I'll give you the news.
I ran 10 psi on stock everything and no meth with 570 or so to the wheels with no problems... Tuning is the key and the tune need to be on.. Everything would be find if you stay around 550... or atleast thats the number everyone agrees with... Me.. i'm fixing to push it to 650 with no meth and see how long it last... then I'll build a motor...
