Can Z28 be Supercharged

[Bhobbs]

Why would you want to supercharge a Z/28? Makes no sense to take a car GM spent so much time and money to strip weight out of and dump all that weight back in.

I personally agree with what you are saying. However, there are some that will do this. I'm not one that would but I know there will be some that will.

Will there be room for us to take out for example, (back seat) and carpet in the trunk to reduce weight!!!!. Maybe make it lighter to make up for the weigth of the supercharger?
Or even if we leave it naturally aspirated we can shave off more weight.

1. Rear seat. (If it will have any)
2. Carpet in trunk
3. Air compressor with Fix A/Flat
4. Change out regular battery, for a small weight reduction Battery.

Any other ideas without taking out making it look ugly in the inside...

Ill put down the money and time.
Some say yes (stock) with a moderate boost. Some say it has to be converted to low compression.
Some say the walls are to thin and with time of been supercharged, it will blow up

I'm going to say this and not engage in further debate with others on the subject. I've said above that you could s/c this engine if you really wanted to. I'm sure some of the vendors here have packages to do this since this LS7 has been used in the C6 Z06.

Here is the statement.... When the LS7 engine was architected by GM it was scoped as an NA engine, period. If it was meant to be s/c'd it would have internal differences more suited for boost. I personally think s/c'ng a Z/28 would be a sin. Just my own personal viewpoint.

What is your goal? What do you want the car for/to do?

I want a Z28 , but of course with more power than stock.
I like the winding sound of a supercharger. Just wanted something different that will make my Z'zz stand out.

You do realize that adding a supercharger will add weight to the nose? And all your weight offsets you've mentioned are in the rear making it even more nose heavy? My opinion (and you are free to disagree) is that the Z/28 is not for you.

So you don't really want a Z/28. Why not buy a ZL1?

I just want to make my next monster be a Z28, next generation Camaro or the new z06/C7

You can easily run up to 8psi with the stock cam without having to worry about ANYTHING.

Second of all, the guy who said 11:1 CR forgot or perhaps doesn't understand that those numbers reflect static compression ratio only and the dynamic compression ratio is what you have to worry about, without doing the math I actually think theyre either dead even on DCR or the LS7 might even have a lower DCR im not sure.

The LS7 can easily make 650rwhp without breaking a sweat on the stock cam, drive like a stock car. The other way to make 600+ rwhp is to go overkill on the cam/head and the other bolt ons. For someone who wants to use his car on a road course, NA is preferable obviously and is also lighter and wont upset the cars weight balance.

what ayousef said .

Ive tuned several force induction LS7 ZO6s, and let me tell you they are a rush to drive. Easy 620 RWHP plus. Dont go crazy and keep the boost at the 6 to 8 pound range and I havent seen a problem.

It wouldnt be my choice for road racing

This doesn't really state your purpose, goal or intended use. Which will help us help you decide what is the best route to go.

Look at it this way. The Z/28 is like a fine single malt scotch. You can let it breath and put it in a very nice glass to drink it from, however you don't use it with a mixer. Why? That's not the purpose for such a special and expensive drink. There are other scotch's made for that intended use.

Without damaging the balance of the car and the repeatability of performance on long race days, what is the most horsepower you can realistically squeeze out of the LS7? I would guess you quickly have to address the valve train issue that has dogged this engine on the Corvette forums but then what and how much? I am from the old school, big block 427 days where more cubic inches, lift, duration, fuel, and spark ruled the day. I have looked at what Hennessey is doing on their LS7's and wonder if that would be a good application without hurting the road coarse focus of the car.

[Callaway Chris]

I've driven many 7.0L LS7-powered cars which have been supercharged beyond 650 hp, all have been a blast to drive, with gobs of torque on tap, endlessly!

The key though is the fuel system

I have my eye on the new Z/28 and if my wife can be convinced to drive a manual transmission car, maybe, just maybe...

Why you would want to take a limited production car that is built for track performance and mod it is beyond me. If you have the money to purchase the car and do what you want with it though, go for it! If I was going to spend 75k on a new Z-28 I would track it on weekends and that's about it.
