I purchased a 2012 GS Convertible M6 new in December and have been lurking on the forum since. After hearing the positive commentary on the Edelbrock E-Force supercharger I elected to take the plunge.

I live in Miami and investigated the local installers and solicited quotes for doing the job. Ultimately, I ended up purchasing the kit from DynoSteve here on the forum (otherwise known as Steve Leerentveld at RDP Motorsport in Ohio, 440-358-5500) and had the installation done by Rob Koeppel (Forced Fuel Injection in Miami, 305-235-6160).

I can't speak highly enough about either Rob or Steve and their respective companies. About a week after placing the order a big Edelbrock box (about 4' x 4' x 2') arrived at my office. Every single part required for the install was in there. Rob and his crew did a meticulous (bordering on neurotic) job of the installation. I received the car back with not a scratch nor a fastener not re-installed.

The real beauty is what the E-force has done to the car. I mostly drive the car to work and had enjoyed how the original LS3's low end torque sponsors gratifying lazy shifting. I launch in 1st, shift to 3rd about 10MPH, and then 5th about 35MPH. The low end torque makes for a gratifying feel without a lot of shifting work. I didn't want to lose the bottom end and the E-force delivered in spades. Low end torque is improved and the car is simply content to tool around a parking lot or on the road anywhere above 500 RPM without chugging, fussing, or complaining one bit. It is amazing!

Reality is in my normal driving the extra power does not come into play. The extra torque makes the car more gratifying but it doesn't feel any faster when on my typical trip the engine rarely exceeds 2000 RPM. Get this beast on the highway, downshift to 3rd, mash on the throttle, and all of sudden you realize what 600HP feels like. It feels good. The speedo more resembles the tach. With a brief mash on the accelerator, the car vaults past 120MPH effortlessly. Obviously, exploiting the new found race in the car too often won't lead to anything good, but it is sure nice to know it's there if you need it.

It was near 90 degrees here in Miami this weekend. I drove the car to South Beach for lunch and a drink. Did about 20 miles on the highway before hitting bumper-bumper for the last 3-4 miles. Temperatures crept up to 212 and just stayed there. AC on the whole time.

I couldn't be more pleased with Edelbrock, RDP, or Forced Fuel for their parts in helping me build the most gratifying super car a fellow can own for not too many $.

Cheers,
Segredo

Congrats! Excellent choice IMO. A reasonable amount of power with good drivability and dependability.

 

Thanks so much sir for the feedback and thank you very much for your business

Very nice and the E-Force is a clean looking blower

 

I made an almost identical post after our Eforce was installed and still love it just as much.

 

Thats great to hear Raul. It was a pleasure talking you through your purchase. I hope you get many many miles of awesome driving.
From the pic you posted it looks like a nice clean install by the guys. Well done to all
Cheers

It's been over two years and it's still awesome every time I drive with it.

 

I am curious. You state your GS is a M6, but the pics show an automatic?

 

Absolutely a manual. What pictures show automatic?

 

The link that says more photos here.Oh sorry, I now see the clutch mc, but I saw a battery by your intercooler tank and I thought all manual GS's had a dry sump oil system, but I see your dipstick on the pass side, not in the dry sump tank like most I have seen. The dry sump GS's have the battery in the rear to make room for the oil tank.

 

Yes. Manual GS convertibles don't get the dry sump treatment like their coupe siblings.

 

That was a really nice review. Most of us are always looking for reviews like this should we decide to modify our daily drivers.

How many days was your car in the shop for the install?

Glad to hear your experience has been so positive.

Enjoy

 

The car was in the shop for 3-4 days. Installing super charger (and intercooler radiator, waterpump, reservoir, etc), pinning the crank, and connection of hoses, wires, etc. took the shop about 16 hours. Its about 200 steps.

I elected to install the more potent #1591 kit, which requires a swap of the fuel pump. The fuel pump is a significant part of the install time. 4 hours for a manual car or 8-9 hours for an automatic (because the transmission needs to be moved/disconnected).

I originally contemplated personally doing the install, except for the fuel pump (which I was planning to let the dealer do). I am glad I left it to professionals. Pinning the crank requires a lot of disassembly which is significantly facilitated by having a lift.

 

Glad you're happy. It looks like a nice clean install and I like your colour combo on the car. Enjoy!!

As a side note the only C6 convertible with the dry sump is the 2013 427 and all of those are M6.

 

congrat on the result! E-force is the twins bro of my ls9 so i couldn't disagree about about the low end torque. which your drive your car 80% of the times!!

 

how are those back tires holding up buddy
