I am looking for the current wisdom on superchargers for a 2008 LS3 automatic. I want to keep the car pretty stock; no desire to change cam, headers, pulleys or fuel pump. I read many of the post from 2010 about E-Force superchargers and it seems like many got very good results. Seems like there are also a number of folks big on the centrifugal superchargers. I am a DIY kind of guy and want to install it myself and if I can avoid a custom tune that is a bonus. I am looking to pick up another 100 HP at the rear wheel I will be a very happy guy.

Thanks to all that have posted many great comments, recommendations and thoughts over the years.

For the money the centrifugals can't be beat and are not bad to install at all. They will also have more room to grow down the road. I would always get a dyno tune though. I'd call andy at a&a corvette.

A custom tune will be necessary. You can expect at least 150 rwhp on a centrifugal system on a stock LS3.

ECS also makes a very quality kit. It will give you that 100 rear wheel and plenty more down the road if you want it.

the A@A system is emission legal if you need an emission legal system

If you really don't want a lot more power later on, the eforce is a good choice. Easy install and very reliable for a daily driver.

For what you are looking to do the standard A&A kit with an Si trim will more then cover you with the supplied pulley.

For your goals I'd just slap on an eforce blower with there tune and call it good. Will be a realiable fast / fun street car. That centri blower at 100 more wheel hp than factory will never feel like a positive displacement blower down low on the street. If you were gonna do meth, headers etc I'd recommend centri style.

Keep in mind with a PD blower and non wide body, the stock 285 rear tires will have a hard time hooking up. Add Z51 or optional rear differential gearing traction will be a even more challenging. I doubt you want to run drag radials on the street, especially in the rain.

I hate to say it but all your points are invalid... First all if you know how to drive drag radials arnt as bad for daily use as everyone makes them out to be. My NT05Rs drove in the rain coming home from a friends last night and lemme tell you there bald as could be, the lines are non existent. Do I got to be careful, sure. But not the end of the world. Another point is a 275 wide tire has been low 4s in the 1/8 @ 170+ so why wouldn't it be ok for a 500 hp Vette? My car has "z51" gearing with a lot more power than stock and at the track I run the car on a 315/35/17 which makes my hearing even shorter and makes me be in 4th basically at the 1/8 and touching the rev limiter in 4th @ a 144 mph trap speed. So in conclusion this guy adding 100 wheel power to his car isn't gonna be anything to worry about.

ECS...talk to them about the tune.

A&A, ECS, Eforce are all good choices and will get you to your goal. Do a little more research on them with the costs and features and contact the companies. mostly everyone is partial to what they have installed on their own car. The truth is all of them are good kits and fun in their own way. Can't go wrong with supercharging the car but be careful...boost is addicting

I've been looking in to this also as I am about to purchase one. I have read so much about the eforce kit having a lot of heat soak after a few runs and then you lose a lot of it's power until it cools down...that is the only thing keeping me from that...so I guess it's between A&A and ECS.

MBB

Eforce blowers have heat soak issues, as all roots style blowers do. Personally for the money I'd just go with a base ECS kit and call it a day. Doug, Chris, and the rest of the team are great to work with.

realcanuk

If you are into racing, you are better off with a centri due to the heat soak issue. For a fun street car it is not an big issue, and those that say it is never had one.

I vote for the centri blower too. A&A's kit is very nice and smog legal if that's what you're looking for. Will drive around town like stock but you'll have that great top end power whenever you roll into it.

Thanks to all that weighed in and offered their insights. I pulled the trigger and ordered a 1590 E-Force kit yesterday. Sounds like the biggest challenge for either solution is pinning the crank. Thanks again.

Fast forward 10 days from when I was undecided....I chose ECS :-)

FrankSemar

Good luck with the installation... Keep us posted, I will do the same

Well....with 220,000 miles on the eaton on the Ford lightining and my c5 had over 125k miles of hard daily use with the magnusun kit...I now have the eforce on the c6z with a pulley and tune....heat IS a real issue but the thing still gets up and moves when red hot without meth.
Enough to crack the throttle on these 90 degree days with a 240 engine temp.

I think that I would go with the magnusun kits over eforce next time though. About to hook up the snow meth kit I bought a couple years ago.
I have never driven a centri car so cant say anything about it but torque down low sure is nice....now theres the variable speed centrifugals right? Dont they offer the best of both worlds?
