I want to supercharge my LS2 suggestions?

[F pilot]

Gents, I have an ls2 in my project 67 chevelle. The car has the complete C6 chassis stretched and fitted. The Ls2 is the original equipment mates to this chassis. I want to supercharge it. Should I go with and ls9 or and Magnussun or kenne bell, Paxton, eldebrock, procharger, what are your suggestions for increased power output, whistle and reliability. ??

your LS2 has cathedral style heads, so that eliminates factory superchargers. If the engine is completely stock, the Edelbrock is simple. But the Whipple and others are good too.

imho...for the money you can do much better of performance upgrades. Have you looked into turbo charging?

[F pilot]

No sir I haven’t and thanks for your input. I am not a fan of turbos because of the power delivery characteristics and their effect on the sound of the car.

I was intending to upgrade the heads also to LS7 or LS9. The car will handle like a Lambo and I am looking for holy **** sound and speed to match.

Being a 4.0 bore, yeah I have seen people swap to LS3 heads. If you do that and go for a LSA set-up it would work, but would require some mods and a tune to get the #s your after. Map out the cost though, it wouldn’t be good to dump money in the LS2 when you could have just bought the LSA. Keep in mind the LS2 doesn’t have forged internals.

Also LS7 heads are different. You can’t use any of the factory SCs with these heads.

Thank you you for your knowledge. I know where there is a 0 hours LSX set up but what about just buying a complete supercharged LS9 setup? What do you think of that?

I'd probably look into Pro Charger if I were you. I wouldn't worry about the internals not being forged as much as being concerned with having a competent tuner. I put an LSA on my LS2 after swapping to rectangle port heads. There is a lot of time and effort that goes into adding an LSA to a car that it did not come installed in. With adding heat exchanger, HX pump, ps reservoir location, the plumbing of those things is time consuming.

I thought about those and frankly they look to be the easiest to install and I don’t have to “scoop” my hood. Not sure the pro charger is going to provide the boost I’m looking for though.
I agree with your tuner comment because that is critical.

[csouth]

They make street and strip Pro Chargers and the also offer different sized pulleys to increase boost. Keep in mind that all of these mods will require supporting fuel system with injectors and pump. You would also benefit from an appropriate spec’d camshaft.

Subscribed. Looking todo the same to my ls2

[CSG]

What do you want the car to do? I have had a lot of aftermarket superchargers so may be able to add some insight.

[F pilot]

I would like zero lag power on demand throughout the ranges from the hole to a big hit at 100mph.

I like the whistle of the twin screw and root type.

[CSG]

What tires? Do you need it to hook or just want power? Auto or manual?

[F pilot]

Just medium comp tires. Want high end performance but I like "buy and Go" for my Chevelle. I just want holy **** power and sound that puts the giggles in my drive. My chevelle will be my daily driver this coming year for the spring/summer/fall so I want reliability. As I said, its basically a C6 corvette with a 67 138 code chevelle body on it. Has the Eibach Callaway multi adjustable suspension upgrade and the engine is set perfectly behind the front axles for maximum handling performance.
So bottom line I just want great, reliable , strong power throughout that makes awesome sound and ****s and giggles.
Bolt and go would be awesome. I probably need heavier springs, different Cams and Minimum LS3 heads right?

I went the takeoff LSA route. It allowed me to build it slow as money came available. I started off with a low mileage gen 4 6.0. Almost finished with it.

Sweet ride!

Here is my old Nova with a KB SC on an LS2. She whined pretty good!

After more research, I’m thinking a set of AFI heads, pre prepped for a SC with a Z51 cam and the twin screw whipple.
I want to DD the car in the summer and I need reliability.

[F pilot]

So, installed the SC, I went with Maguson and put the AFI heads on with the Z51 cam.

Went with Long tube KOOKs headers.

It is at 5lbs boost and just under 650HP at the moment.

Now up for a colour change.

[F pilot]

Car was bought as a WestCoast Custom build but although not to my taste, had all the right bones.
I bought as a C6 Corvette underneath a 138 code Chevelle. All the hard work was done as it was Chopped, Raked, widened, tubbed and the C6 Chassis stretched. It came with the obligatory eibach 10 setting adjustable suspension upgrade. Interior was customized but BUTT ugly. Came with its MONSTER stereo and burgundy paint and blacked out wheels.

What I did to make it mine;

AFR Heads
Kooks headers
custom H pipe
Magnuson supercharger
cam
slate blue paint (Mazda colour)
rerurn to stock look grill and lights (from light bar and phantom grill)
changed wheels
Changed hood (2” riser hood)
Ferrari 458 seats
snakeskin wrap (head unit center console and rear splitter)
re-wrapped some of the interior leather
”D” Steering wheel.

I put the Kenne Bell Fuel pump system in it also. And a bunch of other little odds and ends. Best part is I got to drive it for most of the summer. Stuff would come in and I’d install it. I did have about 2 + months over all but next year will be all fun.

Pretty leaky exhaust though and will be seeking advice.
