Hello,

I am hoping to find a few members here that have experience with the Edelbrock E-force C6 supercharger kits. This is the one I am considering going with. (link below - the 1591 kit - 599 crank horsepower upgrade)
https://www.edelbrock.com/e-force-su...ge-2-1591.html

Question #1: did you install the kit yourself, and if so, how did the install go? (Did you get the model that requires fuel pump modification?)

Question #2: did you utilize the included SCT handheld PCM programmer that came with the Edelbrock kit? (Did it work out okay for you?)



Thanks

 

I installed the Stage 1 kit that doesn't require changing the fuel pump. The SC installation was a blast. I downloaded and went through the the installation instructions to develop a list of tools that I didn't have before the kit was delivered. I did the entire removal of stock parts and installation of the kit in my 2 &1/2 car garage. I did all of it by myself except setting the SC on top of the engine and a buddy assisted me with that. The instructions are good, but lacking in a few areas. If you have experience wrenching, you will be fine.

I did use the supplied handheld tuner thingamajig to remove and save the stock tune from my 2009. I saved it on my computer just in case I wanted to go back to stock in the future. I currently have no plans to return to stock. I didn't like the Edelbrock supplied tune, so I had a local speed shop do a dyno tune and it was much better. FYI, when my fuel pump started leaking a few years later, I had the same speed shop replace it with a Racetronics pump and also add methanol injection. Another tuning session on the dyno and the car really woke up.

I think the Edelbrock kits are high quality and easy to install. I have had no problems with the kit in the many miles I have put on the car since installation. There will be others who will suggest different types of blowers and different brands. Listen to what they have to say as you may want to consider other kits based on their experience.

Good luck with your decision

 

Thanks.

What did you "not like" about the Edelbrock prepackaged tune? Could you give me any specifics.

 

My car had an issue where the idle would drop momentarily when I would put in park. The motor would almost die then it would recover. It didn't seem to really have a lot more power after the install. This was the experience with my car, your experience my be different. As I stated before, a dyno tune made a big difference, Meth and another dyno tune after the new fuel pump made another big jump.

 

Does it require a new hood or any other parts, like fuel system/ pump

 

I installed the Stage 1 kit on my GS about five years ago. Install was pretty easy and straight forward.

I did get the SCT programmer with the tune in the kit. But I don't recommend it. On my car, the included tune was way off. AFR was super rich. On the stock Edelbrock tune, my car made 430 hp to the wheels which was terrible. I had my car dyno tuned and made 520 to the wheels which is what it should have made. And the tune is only valid if your car is stock + the supercharger kit. Add headers and you need to get retuned anyway.

Better to get the kit without the tune and then have your car custom dyno tuned.

As for the fuel pump, I installed a BAP on my car as well as installing the smaller pulley for the 599 HP kit and headers. I figured if I was going to get a dyno tune, why not maximize the gains.

I ran the BAP for a few years but I removed the BAP last year and installed a Z06 fuel pump.

I would recommend (for any car) to install a Racetronix Fuel Pump rewire kit: https://www.racetronix.biz/p/corvett...rness/fpwh-008 It prevents any voltage drop to the pump which keeps the fuel pressure maximized.

 

Mine fit under the hood with no problems. With the Edelbrock kit, if it requires a different fuel pump, it is included in the kit.

 

Spaceme's post reminded me that I also went to the smaller pulley when I had the Racetronix fuel pump and associated wiring and meth installed on my car. Lots of informational Edelbrock posts on the forum.

 

So a few other things to mention.

Hood clearance is fine with the kit but is close. The supercharger lid will imprint the Edelbrock logo in the hood insulation. But for more clearance, Lingenfelter subframe spacers can be used as well as Hinson short motor mounts. I am using some supercharger spacer plates to prevent engine heat from transferring to the supercharger but this raises the supercharger about 1/4 inch. So I use a combination of the spacer plates and a set of ZR1 motor mount brackets which are shorter by about 1/8 inch.

Cooling upgrades for the engine and supercharger are not a bad idea. At the time of the install of the supercharger, I also installed a DeWitts radiator. I also ended up adding a larger coolant reservoir for the heat exchanger loop from Cordes Performance. Adds about 2 gallons to the system. And I also upgraded the heat exchanger to a larger Edelbrock unit that is a popular ZR1 upgrade.

 

Do yourself a favor and get the magnuson heartbeat. The eforce kits are really quite terrible in terms of IAT's, power potential of the kit should you want more, belt routing, etc.

 

IAT is the intake air temperature entering the supercharger, right?
Why is the magnuson better than the eldebrock in that regard, please explain, and will the magnuson fit under the stock hood

 

Lets play way back machine and understand that all the different SC tvs-2300 kits, are just different size pulley, bigger injector, and larger volume fuel pump. The only postie with the 599hp kit,comes with approved ca tune (that leaves power still on the table), to get you through smog.
Note,will get you through smog, but really has the TM values even more lowered them OEM, so counter intuitive, since hobble more instant power as well.

As for LS3 motor, Magie Heatbeat super charger every day of the week, since it will fit under the stock hood, and has better inter cooling, and makes more pressure before it becomes a heat pump instead.

So low down, will need to drop the tanks to change out the fuel pump to unit that will push more volume, your go change the injector sizes on the motor for the more needed fuel as well, and regarding HP just goes down to what size pulley you put on the S/C to increase boost pressure, since the rest comes down to tuner to make the tune safe in the end.

And to remember, with either TVS-2300, if you do hit after hit of boost, the SC will become a heat pump, so budget for a Meth kit during the install.
The meth kit will keep the initial temps down, will increase the octane level of the fuel so you don't run into detonation problems with less than ideal fuel, and since half to the meth mix is water, will not only help to keep the cylinders steam cleaned, but will pick up more power on the done stroke from the water expanding as it turns into steam.

 

I definitely appreciate the replies people are leaving here.... alot of great insight.

I'd like to share my C6 Grandsport's "goals" before I go any further. I'd like to get somewhere between 530-600 wheel horsepower, and no more than that. I feel like this is as far as I can push the car without going into dangerous territory of putting the rest of the drivetrain at high risk. (I want the car to be Sunday driveable, and all of the factory engine/transmission/axles etc parts to survive for 100k+ miles. I am very familar with the horsepower chase, and how it ends.... I've been there done that on previous corvettes. My main goal is to build a durable & streetable survivor.

I wasn't aware that the Heartbeat supercharger was held in a high regard... this is great to know. The question that I have is why would someone choose a Heartbeat over an A&A kit? It seems to be at least around $2700 extra cost. Is it worth the extra money?

What seems to be nice about the E-force, is that it can seemingly easily go back to "stock", very quickly and painlessly if the SCT tuner is utilized. And I could literally do the entire job myself without having to seek out a speed shop to help me. Of course this is all just my perception, and I am currently leaning more towards the A&A kit because I keep hearing that the E-force SCT tune is not good.

thanks

 

I was going to make this comment as well for those choosing a PD blower.

 

Does anyone know where to find a heartbeat sc? I can’t find them anymore I think there discounted? Please let me know if anyone knows where I can find one,dm me!

 

Looks like one on the forum

I think this is the same thing you're looking for the C6
