This thread is intended for those who are interested in an E-Force Install. (Like me)

Questions for those who have been running the E-Force for a bit:

1) 1590 or 1591: Is the only real difference a Z06 fuel pump? Have you had any issues with reliability? Do body panels have to come off for the fuel pump install?

2) Power Increase: Is the power increase noticeable? Meaning, does it throw you back in your seat and make you smile?

3) Drivability: Can you drive the car as it was stock? Does the balance of the car feel different?

4) Fuel: Did you notice any decrease in fuel economy? Was it severe such as a 5-10 MPG change?

5) Transmission: Have you had any problems with your transmission? Either manual or A6? With the A6 are you noticing any wear or slip? Did you do any upgrades so the driveline could take the extra power.

6) Tires: Are you going through tires quicker?

7) Maintenance: Has anything on the car broken as a result of the install? Did putting the E-Force on cause other mechanical problems?

8) Install: Did you install your system yourself or take it to a tuner? Did you have any problems with the install if a tuner was not as familiar with the system?

9) Bang for Buck: Is the E-Force a great deal? Is the price to high?

 

Smooth9883. I believe the specific E-force features and experiences you are asking for have been througly documented in other threads. The forum search function should help here.

 

1) The only difference between the high and "low" horse kits are the high horse kits have the Z06 pump and a 3.5" pulley, the "low" horse kits have no pump and a 3.875" pulley. The fuel tank has to come out for the fuel pump install, this is more involved for an Automatic versus a Manual, but still a labor-intensive job in the best of circumstances.

2) Very noticable.

3) Please see my thread on driving impressions http://forums.corvetteforum.com/c6-f...ng+impressions

4) I lost 1 or 2 mpg in the city, partially I'm sure because the car is more fun to drive

5) No, I'm at 501 rwhp so my clutch and drivetrain is fine

6) No, although it's easier to spin the tires now, I regulate that with common(?) sense.

7) None yet

8) Took mine to EnglandGreen. They were excellent, although the canned tune from Edelbrock was not quite what my 07 wanted.

9) This is a judgment call. You can make more power for less money, but I liked the look of the system, the retention of the stock hood, and got what I wanted out of the system for what I spent. If I'd just wanted to go fast cheaply, I'd stuck nitrous on the car and been done.

 

I've been really enjoying my E-Force and was exactly what I wanted. I have the stock pump with 3.875 pulley (stock fuel pump) and I'm making just over 500 rwhp so no complaints at all. Traction can be an issue at times but it's sure fun to drive. Gas mileage... what's that? Sounds and drives like stock on the street until you romp on it. That was exactly what I wanted!

There are certainly other SC kits that produce more HP and are actually less expensive. To be honest I've noticed a certain biased against the E-Force setup from some reason, but to each their own. Everyone is going to claim they have the perfect setup so you have to take it all with a grain of salt.

I was not looking to create a 1000 hp monster that was going to result in replacing a lot of other parts as things grenaded! Also wasn't looking for bragging rights regarding making huge amounts of HP either.... could not care less about it. It should only be about what you want and works for your particular situation.

I'm happy with the E-Force and consider it money well spent. ECS did my install and did a great job. Zero issues with it so far and it was done in Aug of this year. Everything else is stock except for the Corsa exhaust.....

 

Installed a 1591 in my garage 10 months ago on my 2009 MN6. I am probably one of the very first to do his own install on the Edelbrock E-Force. No issues what-so-ever. Tons of torque, tire spin would be your own doing, fuel mileage is off a bit but I blame my right foot, the kit is designed from the ground up for the C6 Vette...extremely well engineered. No regrets. As mentioned above the only difference between the two kits is the Z06 fuel pump and the smaller 3.5" pulley with the 599 kit. My car also has Kooks headers and a mild cam and I've recently gone to an even smaller 3.25" pulley and larger fuel injectors. My car is self-tuned with HP Tuners. Woohoo!



I also installed a 1590 kit for a good friend back in October on the convertible 2008 MN6 in the photo below. He is also loving the upgrade. His car is 100% stock other than the Edelbrock supercharger. He is also using the Edelbrock calibration that comes with the kit. His car is incredibly smooth and incredibly quiet...until you plant your right foot. I will admit his car did spit a belt off a couple of weeks ago. He replaced it with a much stronger heavy duty belt and is back in business. Forum member "drich2095".

 

I can vouch for the above two installs as I helped with the grunt work of lifting ~80lbs worth of supercharger into the engine bay on both cars. That's really about the only task you can't or shouldn't do yourself. I have driven Motorhead's car and it will go.

I have a Vortech V2 on my car only because the E-Force was not available and I got a smoking deal from A&A. I can't really give an honest comparison because the two SC's function differently and my car is an A6 and Motorhead's is an M6. I would not switch but if I were to supercharge another C6, I would go with the E-Force.

I can tell you that you would not regret installing an E-Force if forced induction is what you're after.

My current set up.

 

I have the 1593 kit on my LS2 A4 with stock pump and 3.875 pulley. My Supercharger was installed by Edelbrock and has the Stock Tune. It was Edelbrock test Car for the LS2.

After the install, you can tell the Car is Faster and a lot more Fun. I broke the tires loose at 50 Mph taking the long way to work on Friday as i entered the freeway on-ramp.

I have notice a mile or 2 less MPG which is mainly due to lead-footing it, just to get that rush and smile. In normal traffic the Car rides like stock, if you are driving normally you will forget that you have a supercharger under the hood.

My eForce quiet just like every one else.


"cthusker", the badge looks very cool, I am thinking of getting one of those. Where did you get it ?

 

Thanks.... Call or email Austin. He's a great guy and will make anything you want... His stuff looks 100% factory imo....

 

1. As others have stated, fuel pump and pulley. Since I used a BAP instead of the pump, I bought the cheaper kit and a pulley. No issues at all.

2. Oh yeah, it rips. I can scare myself. I'm still smiling

3. Car drives as stock. I have not noticed any effects from the extra weight. Maybe if I was road racing, but not on the street.

4. My first tank mileage was horrendous. After that I've been driving a little more carefully and mileage is 1 to 2 MPG down around town. If you like to get into a little boost every time you hit the gas it will show up in your mileage.

5. Not trans problems (A6). I did not upgrade any driveline parts. I have resigned myself to the fact that I might break the trans and am prepared to upgrade it if the time comes.

6. Tires - I already had Toyo R888 'R' compound tires on the back. They are actually lasting longer than I expected. a Side benefit to these tires was a very noticible increase in cornering grip. Without sticky tires this thing would be hopeless. I also just got a set of widened 18" wheels ( See the TRACTIONMONSTER thread) so my next tires will be Nitto 555Rii's in 18" size which are much cheaper that 19".

7. No maintenance issues - I've only got 2000 miles on the setup.

8. Self installed. Very straightforward. It was fun.

9. I think it is a fair price for a very nicely engineered and manufactured system. The quality is apparent. That said , you can get a quality cetrifugal from A&A or ECS for enough less to make a difference. I prefer the packaging of this system to the centirs, and I am very happy with the performance.

 

This reminds me of one other intangible item that was important in my choices.

I know NOTHING about any other supercharger system available for corvettes, but I have done Mustang installs with friends, and thus my limited experience was that a supercharger install involved "Cut this, grind that, modify this, drill that, bend this, etc"

As I read through the E-force install instructions I found only 2 holes drilled into small plastic fan shroud bits to clear the intercooler lines, the crank pinning, and relocation of the horns. Even the intercooler fill tank uses a custom bracket that mounts to the car using existing hardware.

I really liked that I would feel like my car was not hacked up in order to supercharge it. I know that's an awfully strong word to use, particularly given I have NO insight into other corvette S/C install packages, but I felt better knowing the E-force kit was largely a bolt-on affair that could be readily undone without leaving much evidence that it was ever in place.

 

CTHusker, do you have a close-up picture of your badge? Is this the one you were thinking about a while back that integrated something like "E-Forced" into an lS-2 emblem?

 

What's the status of the LS7 version?

Here ya go Jeff.... I tried to keep it simple... it's an LS2 and it's supercharged! Not very original but what can you expect from a LEO... Austin does incredible work, he's on time and can do almost anything you want. He's probably not the most inexpensive around but in this case I believe you are really getting what you pay for.... If you talk to him tell him Craig in CT said hello......

 

Thanks Craig.

<pot stirring>
Maybe I could get one made up that says "Not a Z51 but it is Supercharged and isn't that what really matters?"
</pot stirring>

 

but we all know Z51 is good for another 20 hp! JUST KIDDING!!!

 

I'll settle with my 500 hp. As my avatar shows, I've already got 30 lbs of Wiener

 

Thanks Craig for the contact info, I think it looks great.
