I have a H/C 03', 47m, no problems to date. Anyone with the eforce without internal engine mods experience any issues? In between buying a C6 Z or GS with Edelbrock. Warranty not an issue, did my mods soon after purchase in 03', a good tuner/installer is the key, understood. Stating that, a family member has an 04, vortech (never raced) and imploded his engine with the same rep. tuner in Indy...had a stroker engine by same shop in 94', no issues. Just wondering if the new s/c is worth its miles in fun. I am sure the Z will hook up better, last longer, but the fun at 600+ hp is hard to pass up. Any input is greatly appreciated.

 

I have had my e-force(08) about 6 months. No problems. I have the low end kit with a dewitts radiator-no other mods. Love it.

Motorhead-47 has had his e-force almost a year. I am sure he will chime in. He is very knowledgeable about the e-force.

enjoy whatever you choose.

 

I installed my Edelbrock 1591 kit in my garage a little over a year ago on my 6k mile 2009 MN6 Coupe. The car already had Kooks headers and a mild cam. I have had NO ISSUES WHAT-SO-EVER in over a year and 5,000 miles with this supercharger. Car runs great, has tons of power and has been maintenance free with respect to the supercharger.

As of yesterday I've run 3 different pulleys on the car meaning I've run at 3 different power levels with this supercharger. Pulley swaps take about 30 minutes. I started with the 3.5" that came with the 599hp #1591 kit and then right before Christmas I bumped it up another 50hp with a move down to the 3.25" pulley, upgraded to larger fuel injectors to support the extra power and decided that with the 3.25" pulley I was seriously overpowering the rear tires....car would break traction at 50-60mph when passing! I never dyno'd the car with the 3.25" pulley but it should have been solidly in the 625-650rwhp area with the smaller pulley, headers and cam. It was a lot of fun at that level but not very useful with street tires. This weekend I decided to try the largest pulley (3.875") which comes with the #1590 554hp kit just to see how it felt. To be honest, I feel the car at this power level is probably the best match for a street driven car. For the forseeable future I'll be running the larger pulley. For the record, there are two additional even smaller pulleys at 3.00" and 2.75"...each worth another 50hp or so.

Another data point......I perform all of my own work and have a lot of confidence in my installer and tuner knowing the car was put together as it should be.

 

I had the Edelbrock #1594 Kit installed on my 2006 LS2 A6 last November. My car had 57,170 miles & was stock except for the Flowmaster Catback. 472 rwhp with a very conservative tune. I do need to get rid of the Goodyear runflats, considering Bridgestone RE-11s. I now have 62,325 miles on the odometer, so I’ve added 5000 fun, carefree miles.
Good Luck with your choice.

 

Runnung great without any issues since August of 2010

 

For reliability I'd take the C6Z. As reliable as the E-Force will likely be, it's still an extra potential point of failure relative to a naturally aspirated setup. The problem with the Z is that it doesn't come with an auto.

 

I'll take the E-Force. My stock looking convertible is so stealthy and has more than enough power. My roof comes off when I push a button, not a drive on the interstate!

No one thinks a stock looking convertible is as strong as a Z. Stealth for the win!

I always assume that if someone wants to run they are packing turbos or juice, or both.

 

Seems like everytime I get challenged, they're packing er, uh....rice. Vette guys leave me alone. Mustangs generally know their place (behind). It's just those pesky ricers that won't go away

 

 

I've had my E-Force for 5 months or so and love it, but If I could have the Z06 instead, I'd get it! If you get bored, a cam and some bolt on's should make you plenty happy, or just get the ZO6 AND the E-Force

 

I just had my tune re-checked after installing LS7 exhaust manifolds and cats by Andy at A&A Corvette. The car produced 560 RWHP but the injector duty cycle was at 118%. NOT GOOD! Timing was backed off to 12 degrees and the injector duty cycle came down to 108%. Still not good. Will be putting 60 lb. bar 3 injectors in as the Edelbrock injectors are unless ( car is stock other than exhaust and 3.5 pulley ). The other thing in Kalifornia we are now using a “SUMMER BLEND” gasoline with ethanol. So, like Moterhead-47 stated in his reply he also upgraded his injectors. I think this would be a must for anyone not staying with the supplied “canned tune”, modifying the motor or driving in an area that requires you to use an ethanol blended fuel. To avoid the BIG
KA-BOOM $$$

 

It seems like the E-Force is a pretty reliable option. Haven't read anything bad about one yet.

 

The Edelbrock kit ships with the same 52lb Bosch injectors that the ZR1 comes with. Injector size was chosen to match the rest of the kit and the targeted performance level. In Edelbrock's eyes you would have chosen the competition kit and selected injectors to match if you were going to go modify the setup...just giving you their rationale for the 52lb injectors.

I'm surprised that you were seeing 118% duty cycle though. Do you have other mods beyond the Z06 exhaust? What fuel system upgrade are you running? The Z06 pump or ??? Have you checked your fuel pressure? If you have lower than normal fuel pressure (inadequate fuel delivery) you'll see a high injector duty cycle trying to compensate. Before you buy larger injectors (I bought the 65lb FAST injectors) make sure your fuel pressure at the rails is what it should be. I haven't thought through the math of the increased fuel supply demands of all the blended fuels but no doubt it has an impact on fuel demand at the rail.

560rwhp on just the 3.5" pulley with exhaust is a good number

 

Two weeks ago I got challenged by a Ford GT and a couple weeks ago a C63 AMG. Around these parts its not just Subarus with 3 ft wings. Oh, by the way

 

any tips that you could share about what to watch out for and special tools etc?
i read the installation instructions that edelbrock posted on their website and i am sort of intimidated by the possibility of screwing up the timing

 

Here are a couple of threads I put together on the Edelbrock install…grab a cup of coffee and read through them. That should help.

Fuel system is fine. Motor is stock. I am running a boost-A-pump, just injectors can't keep up. So, something to lookout for if you deviate from what Edelbrock intended your kit to do.

 

Install a wide booty. It scares the ricers. I haven't been challenged since.

 

If you get much passed the LS2, headers, mild cam, springs Corsa and fast cats then the E Force w/3.50 pulley and the big pump to boot you have a deeper bucket seat than I am sitting on
