A2: We offer two main multiport EFI systems with our Wild Card and Joker. These kits work with SBC, SBF, and comes in a Stand Alone Option!

A3: Check out our Killshot and Royal Flush! They have a 4150-style flange throttle body and can produce up to 650 HP! As long as your system can support that, you should be good to go!

A4:  It depends on what you are wanting to do with your build. To break it down into simple terms you need an EFI system/kit,  ignition system, and a fuel delivery system. If you are wanting to run timing control, check out our High Roller Pro Ignition Package. Otherwise you need a distributor, coil, and wires for your ignition.

A5:  Our technicians recommend running any EFI compatible fuel system that is regulated at a minimum of 42-60 PSI and runs at 200 LPH.

A6: Yes! Unlike most aftermarket EFI systems, Aces makes a special ECU for their kits so that customers can use HEI with as little RFI as possible!

A7: The Royal Flush is the same as the Killshot system except it has an integrated CDI box built into the ECU unit. That way you control fuel and ignition from one handheld device!

A8: The Joker is the same as the Wild Card system except it has an integrated CDI box built into the ECU unit. That way you control fuel and ignition from one handheld device!

A9: The main differences between us and our competitors is that our ECU's are located away from the throttle body, keeping it away from the heat and exhaustion! Another thing that is different is that our ECU's have 32 bit architecture design while our competitors have a 16 bit architecture design. This means that you have a wider range of tuning capabilities! We pride ourselves on Customer Service, Quality, and we are Owner Run and Operated.

A10: Currently, our systems work with E85 fuel. It is something that You have to tune yourself, but our systems can run it.

A11: Our technicians recommend a stock to mild cam, 8” vac or more, for the smoothest performance. A more aggressive cam will work but it may require a more challenging tune.

A12: We are not marine certified because of possible  O2 sensor issues. However, we have had customers install our systems on boats and have success.

A13: No.

A14: A: For Timing Control with the Killshot, you will need one of the following configurations in your ignition system:

1.) A magnetic distributor and the Aces AC2008 coil.

A20: It is nearly impossible to establish how much clearance there will be without physically measuring for clearance (due to engine placement, any aftermarket components, and air filters). But the Aces throttle bodies measure approximately 3-5/16-inches from base plate to air cleaner mounting surface.

A21: Currently, the Killshot features a basic timing retard for nitrous oxide applications, but it does not have nitrous control capabilities. The Killshot was designed to be compatible with power adders, but much of the functionality is not yet unlocked in the tuning software. Aces engineers have yet to finalize the testing for boost and nitrous applications.

A22: The Killshot has four sensors that are inside the throttle body: TPS (Throttle Position Sensor), IAT (Intake Air Temperature), IAC (Idle Air Control Valve), and MAP (Manifold air pressure), as well as two external sensors, Wideband O2 and Coolant Temp.

A23: The Gambler Series distributor is designed to work with the Wildcard EFI.
