How much weight does a Pro charger or Vortech kit add to the car. And do you feel the added weight at all?? Thanx

 

I don't notice it! The front dam is an inch lower. not from weight it lower with spacers for the intake ! but as far as the maybe 45-50 pounds they add no. I'd say it's a non -factor.
My box was shipped weight 60lbs and was thick and had lots of packing.
Every things Alum except the blower and thats heaviest piece!

 

About 70lbs and no, you won't notice it.

 

I've posted this before, but you probably never came across it, so let me re-post since I think it is a good answer to your question:

In order to clear the intercooler outlet, the supercharger installation moves the entire radiator bracket 1 inch closer to the ground; that is responsible for most of the scraping you hear about since the rubber airdam attaches to that bracket. The front of my Z51 car dropped some too; I trimmed a little bit of the airdam and raised the front back up to factory ride spec via the stock bolts and now my car has the exact same ground clearance it came from GM with.

Weight wise... Yes, it does add weight, and it adds it at the worse possible place. But lets look at how much is added:

The complete supercharger kit, according to A&A, weights 75lbs. I think that's a fair estimate.
To install it, I had to remove the idler pulley, the intake, the radiator shroud and the top and bottom radiator support. That's an easy 10-15lbs. Then take into account the fact that I removed the factory cast iron exaust manifolds and massive factory catalytic converters and replaced them for stainless steel tubular headers and 2 compact high flow cats located behind the front axle and that's another 20lbs removed right there. All in all I have maybe 40lbs additional weight up front from what the factory intended. If/when I remove my battery (25lbs) and relocate it to the trunk, the weight balance will be right back where it was to begin with, if not slightly shifted to the rear.
Then I can shave another 15lbs from the front by installing a lightweight flywheel and a lighter clutch, and make the car's mass more rear biased.
And that's not even taking into account unsprung mass reduction; the non run flats I run remove 22lbs of rotating mass, and when I get 2 piece brake rotors there goes another 12 or so. With the right mods you can have a supercharged car with less weight and better balance than a factory vehicle, without having to remove any sound deadening or sacrifice any of the comforts.

Finally, lets assume just for the sake of argument that we removed nothing from the car and instead just added 75lbs to the front. 75lbs in a 3300lbs car (assuming vehicle + driver + fluids and fuel here) represents a weight increase of 2.27%. Maybe a professional driver on a race track could detect the slight increase in understeer that would theoretically create, but I am going to guess that the 35% increase in horsepower will do more for your track times than those 2.27% additional pounds up front, and if it causes understeer, a bump up in the rear tire pressure by a few PSI will return the balance. If it still wants to understeer, give it gas; the back end WILL come around. At any speed

 

Saved for a future read.

Long weekend, my brain couldn't handle it.

 

Cliff notes: It adds 40lbs that can be offset by moving the battery to the trunk and/or running a lightweight battery, and has no noticeable effect on the handling of a car that weights 83 times as much as the supercharger

 

Great info, thank you very much!!! Lenny

 

You will notice the power and care less for the weight it adds

 

do you notice a difference when you use 3 gallons of fuel from the gas tank?

 

About 70# sounds about right. Front dropped about 1 inch. I raised the front up 1 inch and had an alignment.

 

Im not sure what the kit weighs but I do have this to say. Last season I was bone stock, and at my local drag strip I weighed my car. It was 3175lbs with no driver and a half tank of gas completely bone stock. This season I was at the same track on the same scale. My car with an A&A vortech kit, b&b bullet catback, factory repro 08 c6 wheels and a FULL tank of gas and stock tires was 3000lbs EXACTLY. Somewhere I saved atleast 200lbs with the extra gas that was in the car. Im sure the catback and wheels saved alot, but I'm not sure how much the kit may have saved or added. Please note that I did weigh myself on the scale after my car was off and it was perfect down to the pound. I couldnt believe it myself. My car, blown with 550rwhp at only 3000lbs with full fluids.

 

Impossible, scale sounds right the first time second time NO!

 

Same scale. My buddies C5 Z06 was like 2950lbs that same day with dragradials and no pass. seat.

 

Must have the helium mod, you added a S/c, aftermarket wheels and
with a full tank! All heavier items! But weighed 200 less and think it may BE right? You would have to strip the whole interior and a fender or two and still wouldn't lose 200 pounds! plus the weight you added!

 

I own a scale company. Those scales are out of calibration.
