Hey guys. I just bought a 07 z06 and I love it. The car is bone stock with 20k miles on it. I first plan on putting on a set of American heritage heads to fix the head problem. After that I want to put a supercharger on it to add some extra power. I am leaning towards either the eldlebrock or the heartbeat because I like the looks they give. They look factory. I know I will get more power from a a&a or ecs but want to stay with the roots style like magnuson or heartbeat. Just curious which setup is better. Any opinions which one to go with? The car will be 100% a street driver. I will not be racing the car. Just a fun driver and burnout machine. Reliability is a must as well. I don’t want to worry about that.
Thanks for your help

For what you want, buy whichever one you get a better deal on. Both are reliable and fine out of the box, and since you are not concerned with power or racing, just save the most money and go with the cheaper or better looking of the two.

For a burnout machine either one will get the job done.

I think the HB looks way better but both would work fine.

Thanks for the feedback. I mean of course the more power the better lol but going for a little more of a factory look than the centrifugal look. I had. Pro charger on a 05 c6 I had a few years ago. I loved it. Car was a animal. But with this being a z06 I figured I would go for more of a factory look. From the research I have done, it seems like the heartbeat makes a little more power. Or are they about the same? The heartbeat fits under the hood ok? I read you have to either remove the hood liner or use the lingenfelter frame adapter? Had anyone driven both to know if one had more of a supercharger whine than another. In my last truck I had a Toyota Tundra which I put a Toyota supercharger on which is made by magnuson and it had a really nice whine to it. With the corvette being louder you might not hear the whine as much though.
Thanks for the help

The Heartbeat will fit under the stock hood (with hood liner) just fine. Only place that mine rubbed was on a clamp that held the rubber connector from the CAI to the throttle body. It was very minor. Never bothered me. You could probably clock the clamp to be at the bottom of that connection and not rub at all.

You won't get a lot of whine out of either of them. The internals are exactly the same between the two. ANY kind of exhaust noise will drown out the little bit of whine that's there. That's one of the many reasons that the OEM's like them.

Oh, and despite what you read here sometimes, you can outrun a lot of higher horsepowered rigs in curvy and straight line racing.

Great info. Glad to know the heartbeat fits under the hood. I’ll just keep a eye out to see who has a better deal out there.

I have a max effort e-force on my Z ...car feels amazing but I do have a built motor ,head,cam and the rest of the supporting modifications also have borla exhaust and I’ll tell you one thing you will definitely hear the blower wine over the exhaust ...if I had to do it over again I would just use a centrifugal supercharger because I don’t like the wine....

Stop whining !!!

How about the Whipple?

Unreal

Whipple is a decent blower, but doesn't fit factory hood, so add $1000-4000 for a hood.

IMO, centri kits are the way to go.

I know most like centri's but like the original poster, I'm looking at roots types as well. If I had the choice, I'd be going Whipple.

Unreal

IMO the heartbeat is a better choice. Fits under stock hood, fits great, makes good power, and just works. The extra cost and power cap of the whipple just doesn't work well on a vette like other platforms.

Heartbeat of the two.

Doesn't Chevrolet sell a COPO with a Whipple on an LS?

Yes, I think that is the case. Still need a new hood on a C6 though.

A Heartbeat running an 81 mm pulley on a Z06 with headers would be a good option. You're looking at mid to upper 600's at the wheels with only 8ish psi of boost. A Heartbeat spinning at that speed will have little to no whine.

That's how mine was pullied and it was virtually silent in and out of boost. When you spin them up way past that, you do get more whine.

Unreal

That is one of the issues people don't get. A blower is more than just a blower. It has a manifold, intercooler, heat exchanger, etc. A whipple is a good set blower, but if it is packaged on top of a tiny restrictrive intercooler, crap manifold, etc it doesn't matter. Same thing with some of the centri kits. Some have much better brackets, belt setups, intakes, etc.

A PD blower on a mustang can crack out huge numbers with ease because the DOHC setup gives a huge valley, and tons of hood room to make an awesome PD setup. Similar with the camaro, much more room for better packaging. Vette is limited, and suffers from it. So comparing to a camaro doesn't mean much.

i have a 2012 base unit that i had Lingenfleter put on a tvs2300 magnason dyno at 518 rwhp quite and power. Lingenfleter has a 1/4" shim to fix hood clearance. just my 2 cents
