MSD Atomic FI

Before I jump, does anyone have any words of wisdom?

Holley Terminator.

Dave, After much review and research I am going with the Atomic EFI as well. Selling off all my stock 5.0 EFI now.

Thanks! I've been looking at both....did you buy it yet, Glenn?

[HotRod47]

Not yet. Waiting to sell off my EFI parts first. Soon I hope.

Looks like a nice system, but one drawback (just from what I've read) is it's a sealed unit so if a sensor fails you have to crack it open yourself and possibly void the warranty, or send it back to MSD. I just installed FAST EZ-EFI (version 1) and the sensors are all accessible and GM based, so easy to replace if needed.

Just remember that with the Holley you can change out to multiport injection at anytime. It is basically the HP system with throttle body injection. With the FAST and MSD, it will always be throttle body injection. Something to think about. Everyones plans change and upgrades are inevitable.

Thanks! My plans chage daily.....Lol! I've been reading everything I can, and I'm leaning towards the Holley...I just need to figure out the fuel tank situation.

If you have questions, and need assistance regarding the Holley EFI, just let me know. Thanks - Derek

I can highly recommend the holley terminator-it works great, wasn't too hard to install..

Ready for the Power Tour?

i was looking into the MSD unit also, but went with MASS-FLO EFI compare them with Holly massflow it a true efi due to them using a mass sensor

@ Derek;

The terminator looks nice, BUT:

What if you have over 700HP?
And will it support E85 (my future plans)
How does it combine with SnowPerformance water/meth injection? (I have the nozzle in the intake, directly under the carb)
And can you program it so you have a economy and a race setup, activated by a button. (like the Mini Cooper)

Have you looked at MegaSquirt, It will do everything you want.

Before I would buy the MSD setup, I would question what happened to the last fuel injection set up they made? I would go with FAST or Holley.

Put 2900 miles on my terminator on the power tour. No issues at all with it. Basically got it installed right before I left with little to no testing. It's a great system!!

If you have 600+ HP, throttle body injection should not be used. MPFI system should be your focus. None of our systems are E85 compatible. You can save as many tunes as you like on a laptop. Simply select what you want to run, and load it. Meth injection will not have an effect on the EFI setup.

Glad to hear it went well.
