Holley Performance Products Terminator EFI

[Derekk]

I'm happy to announce that Holley is taking pre-orders for the Terminator EFI kits. The polished units, 550-405, will be shipping mid May (according to manufacturing), and retail @ $1999.95. The Hardcore Gray units, 550-406, will ship at months end (according to manufacturing), and retails @ $2049.95. These units will include the ecu, harness's, sensors, and throttle body assembly. fuel pumps/lines, fittings, filters, and regulator will need to be purchased separately. Please call the tech line if you would like to inquire about these units. The tech line is open 6 days a week. 270-781-9741.

Cool looking setup. Ill be in the market for this stuff in about 6-9 months. Can I ask how this is better or any different than the FAST EZ EFI setup?

[Merlin]

There is no specific mention of a wideband O2 sensor. I assume it does not come with the kit. Which brand/type do you suggest?

I believe it controls timing (with the appropriate ignition box) and is laptop tunable if you want to use one instead of small handheld unit. Can also be upgraded to work with boost. I didn't care about that stuff, so recently purchased the original EZ-EFI. If I didn't already have a programmable MSD 6AL-2 I would have strongly considered this new Holley unit, looks like a great product! And much better appearing than the other Holley throttle bodies!

The Bosch wideband oxygen sensor is included with the kits.

With the EZ EFI systems, the ecu is very limited in what it can control, and what the end user can manipulate in the tune. The terminator will come with the same ECU that has been in the Avenger, and HP efi systems for 4 years. The ecu can control timing with several different types of ignition systems (HEI, TFI, COP, Waste Spark DIS, crank triggers, etc), without requiring the use of additional modules. Also, it can control 4 inputs/4 outputs which can be used for electric fans, driveshaft speed sensor, nitrous control (progressive 4 stage control), boost control, traction control, and many other functions. What makes the ecu more flexible is the fact it can be used on a throttle body injection, then simply switch the engine harness's if you want to swap to Multi Port injection. The ecu also allows the end user access to tune in speed density, alpha-N, or combination modes. This is great when you have a big nasty cam, and need to tune the idle area to compensate. So in short, the EZ EFI ecu is primitive when being compared to the Holley EFI computers.

Finally. Will be ordering soon. Good price compared to others (F.A.S.T., MSD).

It's a really nice piece.

How does the height of these throttle bodies compare to a standard 4150 carb height? I've long considered putting one of these style setups on my FFR but I have virtually no room to spare under the hood. They appear taller in pictures but that could be optical illusion because they don't have bowls to lengthen them out.

BTW very nice looking piece! Now what about maybe getting with ATI so they'll produce a damper shell to go with your 60-2 DIS system :-). Us PT guys can't afford to space everything out for the reluctor wheel due to the front accessory drives.

Thanks!

The Terminator throttle body is 3" tall from the base to the air cleaner flange. I'm not sure who you have talked to, but John, and Chris @ ATI confirmed that they will machine the 60-2 trigger pattern into a shell. So your concerns shouldn't be a worry any longer. Throttle body is shorter than the Holley Ultra HP carbs (3.25" from base to air cleaner flange), and ATI will build you a balancer with any pattern you want. Let me know if I can help further. Thank you, Derek

Hey Derek. Thanks for the follow-up. I should've been more specific. You are correct. When I spoke to ATI back a while about this they did say they would build a shell. Matter of fact, they had built a few 60-2 shells for NRE. I assume those were for Electromotive ECUs which may be same as your 60-2?

The primary problem was that it was considered "custom" and thus had a long lead time and was priced as such, i.e. significantly more than a non-custom trigger shell. The number I got was $800+ or something for the shell. There was also a good bit of risk with that because it was on me to provide the design requirements. They've since worked with AEM to develop a trigger shell for the Infinity system and that new shell appears to be priced closer to their typical trigger shells. That product release was what triggered me - pun intended - to think maybe similar could be done for Holley.

Anyway, I was just thinking maybe with the popularity of the newer Holley EFI w/DIS that maybe you guys could work with ATI to get them the correct info they'd need to design the shell. Then maybe it would be closer to a "stock item" than a "custom".

I called about a month ago to inquire some info on this unit. I was trying to find out if this unit could be used with a nitrous system (plate style). Was told that this unit was still being tested, and that it has been talked about and may be a option. So has this been addressed or can it be done with this unit? Thanks

I can probably get you the pattern. I don't see where it would be a big deal. Before I release it I would have to get approval. I didn't think about asking them a price to machine one. I've been slammed since I came back to work. Data logs, emails, and phone calls keep me very busy. If I get a chance to follow up with ATI I will surely do so.

You could run a wet plate under the throttle body. However, it has not been tested, and the tune ups would be something for the end user to figure out. My suggestion, if considering this, would be to have the nitrous system flowed for high pressure. I wouldn't suggest a dry nitrous setup at this time due to the injector sizing. We are very limited in resources, and it's a stretch to release what we do, all while working on 6 other product lines. FYI, if anyone has called us in the last 3 weeks, you should get that feeling. 35-50 minute wait times on the tech line :(

I talked to ATI last year as well. The shell is $350 and the lead time was 8 weeks. That is to put on your existing ATI damper. The issue is where to put #1. It will be different with different engines. They have LS and SB Chevy clocked, put you have to provide the info for anything else.

I agree it would be nice if Holley offered this as an option, just one more advantage over the other guys, but probably way down the road.

I can't dictate what another company charges for a balancer. However I can tell you the pattern is very straight forward. 60 evenly spaced teeth, with 2 teeth removed during machining. The teeth have the same amount of "rise", and "fall". I could give you the dimensions for our wheels, however the diameter of the balancer changes the spacing between teeth. So my trigger wheel may not have the correct pattern for your applications. Another viable option, is Innovators West. I've been using their balancers for many years with success.

Does that line on the left of the carb come up to the top of the tb? I have a roller 466 and the next mod is fi but its gotta fig under a formula hood with a torquer ii and a drop base air cleaner.

Very interested in this setup.

The inlet comes in on one rail, goes through the cross over (does not go higher than the air cleaner flange), then exit's on the opposite rail. The regulator is installed after the throttle body, and the return line goes from the regulator to the fuel tank.

[70Uglybird]

I don't think that is doing to work with the formula air cleaner. Is that a hard line or can it be adjusted/modified to hand sideways? Ill have to see if any local shops carry it to test it.

I'm currently setting up my fuel system. Can wait to try the Terminator efi. What is the size of the fuel fitting? 08-an, 06-an, 06 orb, 08 orb? Thank you very much.
