HP/$ your never going to beat nitrous...
With that being said...it does make some pretty strong gains across the board, but it isn't a cheap upgrade.
Compared to other blowers, it drives a lot differently and has it's own set of benefits and draw backs.
Take a centrifugal blower like a ProCharger/Votec unit. They make awesome PEAK numbers and make a lot of top end...more so than the E-force. For those guys spinning the cars up in the RPM's it makes a lot of since to do it. They will also support a lot more HP than what this will.
The E-force is going to be more suited for someone that wants power, no drivablity changes and wants the car to drive like a big block. They make so much more boost lower in the RPM's and thus make more torque and HP lower in the RPM range that they make for a very fun street car that isn't going to see 5000-7000 RPM all day long.
The new Maggie blowers work the same way, just like the Whipple blowers and they will make more peak power too, but you have to deal with the hood and painting which not everyone wants to do.
It's like every other modification. Make a list of what you want, your budget and go from there.
Always glad to help.

Except for the obvious engine upgrade in the Z06, doesn't the Grand Sport have most everything beefed up including the clutch on line with the Z06? So if true would the concerns about stress on drive line components be less vs. the base Corvette?

Do you agree? How long have you had your supercharger ? Do you like it ?

My vortech headunit is going on this weekend.
If it wasn't said it was certainly implied that the low-end power is a deciding factor. If both overpower the tires at low RPM, what benefit is even MORE low end power?

I'd say that instant big part throttle torque snap you get without having to wind it out.

I believe you are essentially correct however the OP states owning a LS2. The T-56 is not as strong (and shifts more poorly than) as the TR 6060 in the LS3's+. I own an LS2 and am a little paranoid about the t-56 - although I have never had a mechanical problem with mine.

It is a great "bang for the buck" option, short of changing the gears. Where else can you get 150+ HP gain and mid 500s torque for $6,500? You can remove the engine and rebuild everything for a lot more and come close to the E-Force gain. Sure you can buy headers, ignition, or intake stuff to add power but the gains are not that much. So I stick to my theory of "great bang for the buck," if you got the bucks.

BC - where are you finding the Edelbrock E-Force with the options you list in your first post for $6,500?
I'm seeing much larger numbers than $6.5K for the Edelbrock pkg. Please PM if you prefer? TIA

To make this even more biased towards a centrifugal I chose a LS7 vs LS9 so the ATI has a bigger stroke and cube engine to start with. The E-force cars I have done so far have been auto cars (manual car on the lift right now getting one). The LS9 uses basically a very similar TVS setup to the E-force unit, so it was used to compare.
LS7 (blue curve)
- LG 1 7/8 Headers
- LG G7X3 cam
- RPS clutch
- 8 rib drive, 8 psi boost
LS9 (red curve)
- LG 1 7/8 Headers
- stock cam
- lower pulley 11 psi boost
Same tire size, same diff ratio used in both cars (3.42)
You can see how the blowers make boost in different ways. Almost 200 ft-lbs toque difference. Notice the LS7 ATI setup pulls more top end HP, just not the low end...even with the longer stroke and bigger displacement.
That is the closest I have on file for boost levels that I know of.

My point exactly. The huge torque at lower rpm give a feel in normal street driving that (for me) is hard to beat.
550 ft lbs at 3800 rpm is just plain fun. This was before headers. Its 575 now.

We just did the eforce on a 05 auto and we were really pleased with the results. The car made really good torque and all drivability was retained. Between 3k-4k rpm the torque went from 400ftlbs to 489ftlbs, so there is a huge amount of power in the midrange on tap.
The ls7 clutch is a good start for an upgrade in torque capacity. We installed the ls7 clutch on an 06 gto with a Procharger that was making 600hp at the crank. We haven't heard anything bad from him at all regarding the clutch.
The only bad thing we can say is you'll probably have an expensive tire bill at the end of the month. But if you don't, wheres the fun in that?
