Hey y’all I’ve got an 05 vette with the ls2 and I’m looking around at superchargers and I was wondering if the LS9 supercharger would fit correctly? I know i would need a cowl hood or cut a hole. Thanks in advance!

 

So couple issues you'll have to overcome with the LS2... yes its possible but alot has to change. Issue 1, your heads are Cathedral Port, the LS9 blower is an LS3 style square port (same as an LSA). You have two options here, go to an LS3 style head, or buy the adapter plates from Boost District. Now the next issue... you'll need the complete accessory drive off of a ZR1 as it sits further off the motor and if im not mistaken is factory 8 rib as opposed to 6. So belt, balancer, alternator, water pump, power steering pump, ect... now all those things have to be replumbed wired because they all sit a little differently on an ls9. If you want my honest opinion it would probably be alot easier to go with a Boost District LSA kit... lot of LS3 guys have done this with good results and the price isn't that outrageous. You'll need some sort of cowl hood, although I remember seeing somewhere the factory ZR1 or High Rise Z06s hoods will clear the CTSV lid (i believe the ZL1 lid is a no go with the taller factory hoods.) The other option though a little more expensive out of the gate is a Magnuson.. much more efficient blower to start with. Also dont forget fuel, youll need to upgrade injectors and probably smart to do a fuel system while your at it.

 

The LS2 has 'cathedral' shaped intake ports in the heads. The LS9 has 'rectangular' shaped intake ports .. so the ports in the LS9 supercharger will not match up with the intake ports in the LS2 heads.

Also, the front accessory mounting is completely different between the LS2 and LS3 engines, so making the swap work would involve way way too much fabrication and parts.

If you want a Positive Displacement (roots type) supercharger like the LS9 style for your LS2, look to purchase an Edelbrock E-Force supercharger ... or get a Centrifugal type supercharger from ECS or A&A instead.

 

StayInStock and myself said basically the same thing and posted at the same time . .

BTW ... The Magnuson Heartbeat SC is not available for the LS2 (no cathedral ports)

 

Cant share the link because I dont believe their a sponsor but if you google boost district c6 corvette it should take you right to the page you need. Kit starts at $4300 for new or $4200 for a remanned unit.

 

true, I think they might make the smaller one in a Cathedral though if im not mistaken. I havent looked into the Cathedral to Square port adapters but I know they exist. I dont quite see it being that efficient though since its such a radically different shape. Probably the easiest route would be go Centri... but there's a whole other can of worms lol

 

Yup .. For the LS2, the OP would be best served (and cheapest route) would be a Centrifugal type supercharger from ECS or A&A.

 

hey thanks for the detailed reply! That’s a lot of stuff I’d have to change lmao. I might just end up checking out that boost district kit. I appreciate it!

 

yea a previous reply made me realize I’d be swapping over way too many parts lol. I do want a roots style supercharger so I’ll check out that edelbrock supercharger. Thank you!

 

If you want to build efficient power you should check out Race Proven Motorsports video on the Edlebrock chargers on LS vehicles. They dont yield very great results for the cost.

 

TVS 2650 kit and the best of all worlds on the LS2.
Hence Gobs of torque right off idle and since it can put out more volume that the TVS 2300 (that can heat soak when being pushed), don't have such problems.

As for amount of power, 2650 can push you well past 900HP if desired, but on a stock motor, limit the amount of boost to say 700hp with meth kit and long tube headers.
As for drive line and keeping that amount of power hooked to the ground, good luck, since again, TVS torque goes max linear pretty much off idle (not spooling up that you have to wait on, which makes it a perfect unit for street/road course driving).

 

2 more thoughts, the 05 had a 4 speed auto and not sure how well that particular trans holds up to boost and it's been mentioned the 05 had issues with the rear diff being weak...I belive I read they were pretty much fine for stock power but when you run forced induction or nitrous it was decide to scatter itself on the street.

 

Put a pro charger on it. Roots style blowers suck on street cars. To much heat

 

procharger/centri all the way if your trying to make big power, but if you want reliability and factory like drivability a twin screw/tvs setup is where its at. Heat isnt a huge issue anymore with the heat exchangers.

 

Where did you get that little gem of miss information? Your completely wrong. Ask yourself and then educate yourself and do some reading. Why did the ZO6 and ZR1 owners sue GM? HEAT! A procharger will be just as drivable with no issues. Love these people that think they know something.

 

No need to be an *** about it, I wasn't arguing with you, a Centri is still a good setup, but a very different one. I've personally had two different centri setups on my previous car, they have improved greatly and you can get them to be reliable, but they also come with their own set of issues. A TVS is a pretty set it and forget it thing and dont require half the maintenance of a Centri. Yeah they had some issues with heat in the LT4 blowers and your right, they will heat soak. But the aftermarket has more than addressed the issue and people are having great luck. Believe me if I had it to do again I'd choose the TVS every time... but again my goals have changed, I like simplicity. If you want to chase times and numbers then yeah... go with a ProCharger absolutely. If you just want to bolt on 150-200hp with relative ease. LSA all the way. OP himself said he wants a to stick with this style setup (see below)

Real world experience says the TVS blowers run as cool as anything out there. I've had three with literally hundreds or thousands of miles on them. I know internet lore always trumps real world experience though.

One was on a truck that did lots of towing. The other two were on C6 corvettes. The older Magnuson blowers (MP122 and MP112) did run hot if you pushed beyond their limits. TVS blowers are a huge step up from the older blowers.
