Edelbrock E-Force Supercharger

[SkiRideDrive]

Here is the description that came in the email... so yea carb tune I believe.

Dyno Results are in...
Edelbrock's calibration team has completed exhaustive testing and tuning on the E-Force equipped Subaru BRZ. The main objective was to create a calibration that delivers the most power while remaining safe, reliable, and within strict emissions standards. Although 50 state emissions legal status is still pending, we are excited to announce that we have succeeded at meeting the other objectives.
Not only does the E-Force Supercharger produce significant power gains throughout the entire RPM range, it also eliminates the inherent mid-range power dip. The results are smooth and consistent power curves. The E-Force system deliveres peak power of 242 RWHP and 189 RWTQ, for a total gain of 77 RWHP and 57 RWTQ. Want to see the results for yourself?

Does anyone have stock vs jackson racing carb rear wheel graphs for comparison?

I would guess try checking in the JR owners thread...

Just off the top of my head, the JR rotrex spools up closer to 5k rpm, so peak torque is further up the rev range compared to the e-force, which looks to have a nice early and flat curve. I'm not too crazy about the cartoony dyno plot (seems more for advertising) but would be interested in seeing an official, more detailed one.

Either way, really excited to see that CARB will be coming eventually. With Kraftwerks and WORKS getting their certifications, its nice that us Californians can have options.

EDIT: looking @starron post above, looks like peak torque is more like at 6.5k rpm. Either way, looks like the e-force may have more usable torque, we'll see...

You had me at hello.

Jackson Racing Measurements

Peak Torque 150.3 lbft to 216.6 lbft -- Gain of 66.3 lbft

Peak Horsepower 186.5 lbft to 282.7 lbft -- Gain of 96.1 lbft

Edelbrock Measurements

Peak Torque 132 lbft to 189 lbft -- Gain of 57 lbft

Peak Horsepower 165 to 242 lbft -- Gain of 77 hp

The figures above are peak only and don't take into account the twin screw setup from edelbrock to outflow the centrifugal rotrex from jackson racing on the low end.

Also... I believe the jackson racing measureemtns to be corrected. At least for this comparison, we can compare the stock outputs measured by each company. Jackson racing stock horsepower is 186.5 versus edelbrock stock hp of 165. Lets prepare a conversion factor. 186.5/165 = 1.13 or 13%.

Now... corrected edelbrock peak measurements.

189 * 1.13 = 213.6 lbft

242 * 1.13 = 273.5 hp

Now.. a more direct comparison.

Edelbrock 213.6 lbft versus 216 lbft for jackson racing.
Edelbrock 273.5 hp versus 282.7 hp for jackson racing.

And finally, the torque curve for edelbrock, which seems superior on the bottom end from the image... but we need real numbers to compare.

Also, edelbrocks illustration of a torque curve may not match the digital readouts exactly. Only time will tell I suppose.

Also, curious what edelbrock will charge for their setup. Jackson racing charges $4995 with carb tune.

Considering the type of Supercharger wouldn't it make sense to compare it to say the Sprintex as well since that's the closest comparison?

Appreciate your comparo, but to me, still not enough info to make a "should I get this or that SC" comparison. Lots of things to take into account: price, CARB (some take a long time to get it, although Edelbrock has a lot of experience and good track record of getting these), reliability, and application (seems like the e-force maybe a good everyday street vs the JR which is a track proven set-up)

What?! Compare a twin screw to a twin screw?! That makes too much sense for the Internet.

What about the Harrop Engineering SC. They may have information out soon too. They aren't moving along as fast at edelbrock. Maybe they are being more discreet though.

Harrop is another I would like to see, I use a lot of their products on my GTO

Probably... but the Jackson was my number one choice due to reviews and carb until edelbrock came along. So that's where I put my effort in comparing.

Go away troll. If you have something to provide to the discussion please do so.
