Edelbrock E-Force?

Yet another observation....prior to installing the supercharger I was running a Halltech KillerBee with the BeeHive shroud and I am absolutely convinced the Beehive shroud made a big difference in IATs when the car was in traffic. I wish I had the skill to create a "BeeHive" like shroud for my E-Force air intake to isolate it from the heat of the engine bay.

The Edelbrock kit was designed for a 100% stock car. Should not run hot at all given that fact. My car has a few more mods than stock.
The Edelbrock tune does mod the fan settings. Here they are. I didn't fully understand Edelbrock's logic in the selection so what I'm running now is a bit different than their tune.

I've never seen anyone present themselves on this forum as being an Edelbrock tech rep. It would be straightforward enough for those with the resources to build a "BeeHive-Like" shroud. This would give you a head start on IAT's before things had a chance to begin to heat soak. As for the fan settings...beats me.
One thing I've noticed since day one of owning this car is just how long after I put it away in the garage the stock engine compartment stays warm. I could go out there several hours after shutting down my stock car, pop the hood and find a lot of very warm to the touch areas. Adding the mass of the Edelbrock doesn't help things. More mass to cool off and less open airspace to dissipate it.

What I did was squirt the Edelbrock tune followed immediately by a read and save with HP Tuners. What is in that image is what HP Tuners tells me were the Edelbrock settings. Strange. The only alibi I have is that the car wasn't sporting the OEM tune when I squirted the Edelbrock tune.
For S&G's I may go push the C6 OEM stock tune back in the car and then run the Edelbrock installer again to see what happens.

Here is what I have after installing the Edelbrock tune over the top of the stock tune...
And finally here is what I have in the car after installing my HP mod'd tune...

thanks motorhead!
HUH? thats odd with with the canned tune?
my gut tells me it was a 'oops' on their end (not earth shattering mind you), but that tells me that the Quality Control is not at 100%.
Not a deal breaker, but a tiny crack in the Armor of a new product.

I'm not sure what to say but what you see is what I got. I've verified that my fan pretty much performs as you see in both the upper and lower setups but I never ran the Edelbrock fan settings. What I did initially was install their tune, read it with HP Tuners, did a compare with my tune and then went to work tweaking from day one.
Eventually I'll dump all of the Edelbrock stuff and get this car professionally tuned on a dyno by someone who really understands the E38 ECU but the only guy in this area who has me convinced he knows his stuff is "RWTD" and he is a hard guy to nail down.

I'm just guessing but maybe their test mule was a 2008? My car is a 2009 and there were changes in the 2009 ECU that may have some impact...dunno

I too noticed the heat from the extra mass, but the actual unit seems cool. The cast aluminum covers get a lot of the heat and am thinking about taking them off unless they act as some kind of heat sinks that draw heat away 
.
I'm glad I had my headers coated. For those on the fence get them coated.
Also, when I get home and park in it the garage I open the hood up to help with heat dissipation. Not sure if it actually helps.
P.S. Road Rebel referenced his install, it was on my car

Are you running the stock tune in your car? Any ideas what your fan temp settings are?

On a side not, they flat out missed the spark calibration pre 4800rpm on the 08 for sure and probably the entire line.
You can easily pick up 40lb+ torque through the entire bottom/midrange.

I ran a quick compare in HP Tuners between the Edelbrock and ZR1 High Octane Spark tables. Here are the differences...

You got it....went out to the car and reinstalled the 100% factory stock tune that was in my car when new. Here are the fan settings as verified with a read after the initial write...
Here is what I have after installing the Edelbrock tune over the top of the stock tune...
And finally here is what I have in the car after installing my HP mod'd tune...

Don't forget to factor in the "Fan Desired % vs AC Pressure" table. I think you pretty much have the fan running all of the time the minute you hit the AC button.

I've had a couple of people ask about how much boost pressure the E-Force builds. As best I know it here is the math by pulley size.
- 3.875" = ~5.5psi 554fwhp 515fwtq (#1590 kit)
- 3.5" = ~7.5psi 599fwhp 547fwtq (#1591 kit)
---------------------------
- 3.25" = ~9.5psi
- 3.00" = ~11psi
- 2.75" = ~13psi
- 3.875" = ~5.5psi 554fwhp 515fwtq (#1590 kit)
- 3.5" = ~7.5psi 599fwhp 547fwtq (#1591 kit)
---------------------------
- 3.25" = ~9.5psi
- 3.00" = ~11psi
- 2.75" = ~13psi

Edlebrock has posted a E-Force software update (04/20/2010) on their web site for the 2008 – 2010 Corvette and the 2010 Camaro. I have no idea what was changed. Both the Corvette and Camaro files have the same number assigned to them. So, who knows what was changed?
