Default Pro-charger info

Hey, i was looking on the forum saw the ad for the Procharger kit.

The ad said something like 55-60% power increase.. i know its an advertisment exaduration but i was wondering if anyone has the kit on their C4, and is it really as good as they claim.. I know someone that has it for there mustang and he says its really nice hp increase.
Also if it is a 50% or more hp increase its about 150+ HP will i need to upgrade suspension and breaks ect?

Thanks for info...

A 50% increase in power from a ProCharger (or any other centrifugal-type supercharger) is certainly not uncommon. I personally don't have one on my car, but I do know ProCharger makes a very good product and if the price is right, I'd say go for it. Just be aware that the install isn't for the novice or the faint of heart. It can get quite involved and will require some dyno tuning to get everything running proper. But once that's done, the power increase is impressive.

And yes, whenever you consider gains in the magnitude of 140 to 150bhp from a single mod, it is definitely a wise idea to at the very least upgrade the brakes on your vehicle. With all that much more 'go' power, it's certainly important to have more stopping power too.

As for suspension, on a C4 I don't think it's necessary to perform any upgrades other than to ensure that existing components are in top working order. I would consider a good set of tires though... you can't underestimate their importance in handling all that extra power.

Alright Thanks for the info, I will definently look into buying the kit once i pay the car off.

As for tires what would you say just a wider tire?

As for the car itself its all stock only thing new on the car is the coolent hoses i just replaced. I know if i were to get the SC it would be foolesh to not spend the 200$ on a tuneup kit or possible better headers and muffler setup.

If you are able to do it yourself tires will be the last of your problems. Be prepared to spend at least as much as the kit costs to get it to run right. Another way is to give it to someone like Greg @ Blower Works and have him do it right from the start.

If I had it to do over, I would just pull the engine and go with a stroker setup. It would be easier and cheaper. There is no replacement for displacement!

I finally got my log-in/password back after being gone for nearly a month.

I agree with the comment above that it will take more than just the kit purchase to make the car fun and reliable. Once you get to the point where you are trying to get 10-15 psi out of the SC system, you will find that you do have as much if not more in additional mods installed to support the SC route.

Each path (SC, TC, cubes) has it's own share of downfalls, but they also have their own highlights as well. And all SC are not as noisy as say a ProCharger P600B.

The way around the tuning dilemma is to buy an aftermarket ECM computer [ Like a ACCEL Gen. 7 ] a laptop and play with it your self !

Supercharging can get right expensive if your setup ain't right.
Compression is a factor, enough air and fuel is another and when you get that right the drive train needs attention.

If you do start the Mods just make changes like drivetrain fuel exhaust whatever like you will be doing even more ! It's like Drugs ! Highly Addicting ! The need for speed ! Sure is fun when your grin is moved to the back of your head from the torque !

You have an LT1 (OBD-1 ecu), right? Unless you start getting into the low-z injectors territory (typically +50lb injectors), big boost, and big HP, I think "LT1 edit" would likely address your tuning needs. I run a DFI gen-VII, wideband, splice-in harness, and knock sensor on my car, which affords me the opportunity to run a Dual Sync distributor (no more optispark issues) but it is pita to install and tune. I would suggest getting some 50 lb injectors, 2bar map, and some dyno time w/a competent tuner!
Good luck!

While we are on the subject of tuning SC setups, I just wanted to add that Greg @ Blower Works set me up with a Ostrich, TunerCat, and all the necessary cables and files and initial program to get me started on doing my own tuning. I wish I had this ten years ago when I first installed the the 600b. The Ostrich is a Vette's best friend. I added a set of 30lb Bosch injectors, Wide Band 02, got an ALDL and TunerPro and am all set to tweak away. No more paying hundreds of dollars to get custom chips burned. The beauty is it no longer needs to run super rich all the time. Put the fuel pressure back to 43 lbs and no more black smoke pouring out of the rear. Al Gore and all the bicyclists will be pleased.

Next will be some of Greg's pulleys to get rid of that belt slip.

Well, im no mechanic, i have no shop, no friend that has a shop and i only know how to do basic stuff. So if I were to get a SC installed i would go out and pay the 5k+ to get it done. I know it would be a great learning exprience to do it myself but there is to much stuff that can go wrong.

Absolutely loved the centrifugal superchargers on my old camaros, but I have reservations about the C4 due to installation and packaging. not enough room. I got my C4 as something a little more reliable to be built on a budget so that mean normally aspirated motor (if not stock) with only suspension work for now.

You can get like 575-600 hp on an LS3 C6 with a 50 states legal kit for $6000 so I wouldn't even dream of dropping a few thousand dollars into a C4 when I have my 2008 just sitting in my garage waiting for the warranty to expire.

Here are a few of the C4 Corvettes we have installed ProChargers on, and the power increase is everything that ProCharger advertises. Bob

We're going to quit installing, and just do the selling. At least for now. Thanks. Bob
