Eldebrock E-force or Procharger??
These are my only 2 options since I need a CA carb approved charger for smog. I see the Procharger is centrifugal and eldebrock is modern roots style. I understand roots more low end and centri more high end. I will more than likely use the factory tunes til I find a reputable shop in the Bay Area for custom tune. It will be daily driven and tracked a few times a year. Curios what people's opinions are about which set up would fit the stingray better or anyone who has driven/own either. Thank you

I have yet to see a shop here actually have an E-Force in stock, let alone installed.
We all at least know ProCharger has systems working and on the road with the included tuner.

Callaway's patent pending SuperCharger for the new Stingray is 50-State / CARB compliant, and is the only package which has a real powertrain warranty, supplementing the GM Factory powertrain coverage. We are peerless in this regard.
Power, style, and exclusivity - backed by the most powerful warranty in the business! Callaway is powerfully engineered, indeed
We'd be glad to discuss this option with you further - please feel free to drop us a note: info@callawaycars.com

Doh!I'd agree honestly. TVS blowers (e-force) are really nice, but ultimately they heatsoak compared to centrifugal blowers and centrifugal will make more top end power

Heatsoak is not an issue with Callaway's design.

Callaway's third generation Corvette supercharger system is a completely new design. Callaway engineers developed a new supercharger housing and associated intake manifold for improved airflow and increased charge air cooling capability. Intake manifold runner cross-section and length were tuned for a broad torque band while maintaining excellent peak horsepower. Eaton’s 2300cc TVS rotor pack was selected for its high thermal efficiency, OEM-certified quality, and service-proven reliability. A new triple-element intercooler configuration provides significantly lower inlet charge air temperatures than possible with single and dual element designs. Because of the added volume of the new internals, the supercharger housing itself extends through the hood. Consequently, both conductive and convective heat transfer mechanisms are utilized to remove power-robbing heat from the inlet charge.
Cross-section of new Callaway supercharger design,
illustrating improved airpath and compound intercooling
For example, in dynamometer testing, inlet air temperature increased by less than 10şF during individual runs, compared to increases of at least 35şF with other intercooler designs. That means more consistent performance at the track and dragstrip, as well as increased power on the street during summer months. To prevent drive belt slippage, a new 10-rib pulley system has been incorporated. In fact, certain new technical features are significant enough that utility and design aspects of this system are patent pending with the US Patent and Trademark Office.

1. Superoir design uni-brackett stronger and lighter less mass.
Super easy mounting.
Forged pieces the others don't have.
2. Superoir intercooler design. Their's doesn't block the radiator cooling and has a scoup to catch air.. the rest are trying to catch up and copy.
3. Balancer even GM puts a better crank balancer on the new Z.
So does A&A in the kit it's a 600-700 piece at his cost and IS better!
4. NOW Has advanced air straighter insert to make for a smooth Supercharged power.
5. Has hard piping the whole way. Some just have silicon tubes!
You get alot for your money when compared!
He is working to make it better constantly! Great service!

I'm a procharger guy, the company and their head units treated me very well for years. Even in the turbo world I did very well with a D1SC and F1A and a 347 inch LS1 in class engine and blower size limited 10.5 and 275. Plus a few 9-10 second street cars..
But I put a 2.3 TVS (same as the edelbrock blower) on a stock 2011 mustang auto, with just the blower, tune and drag radials it was a 10.70/130mph car. Thats a little 5 liter engine at 4000lbs.
Looking at the C7 offerings, with an auto (if I didnt want to swap torque converters) I would probably do the edlebrock if ETs were a concern and that was the only mod I was going to do. Its expensive and not as easy to install, but the C6 Edelbrocks I have seen were very OE quality.
The Procharger is cheaper, easier to install and most likely a little lighter as well. But will need a torque converter to realize the true ET potential, the lower cost would offset the converter but some dont want to dive that deep into it.
If its a manual you can make your choice, either one will provide enough power to give you clutch and/or drivelibe problems if you take it to the track and try to get a decent ET with sticky tires
But for just driving around with a manual I would probably pick the procharger, linear power increase, easy to tune. No air to water pump/hoses to mess up, less heat soak/faster inlet temp drop with the air to air as well.
Andy makes some nice stuff, so does ECS but the CARB thing is the killer.
IMO its best to wait it out and see some results, its a lot of money to spend to regret a decision down the road. Wait for some real results and user feedback..

I believe the E-force kit was just released.

Thank you for your post - for power - and total performance which we've delivered for nearly 30 years on Corvettes, and backed by a real powertrain warranty, we appreciate your consideration.
