Yeah looks like your throttle linkage lines up a bit better. You can probably tweak the lower bracket over a bit and get things lined up even better.

Andy, do you plan on testing the Super Sniper 4500 at any time?

No, I do not have any plans to run the Sniper 4500. I'm a little over committed on projects right now so I'm not looking to take on anything else.

Apologies for the hijack here but what studs are you using on the water pump to block? I've had a gasket go behind the motor plate at the track before, this set up would make it a bit easier.

I built a bracket to hold the digital dash screen where the radio used to be in my Coronet. I'll give this a try to see how it works. I'm sure I'll change the design over time but this was quick and easy to build for now.

Just an old Coronet. It was a street racer back in the 80's and then I was going to drag race it in the 90's but I never really got serious about it. Now I'm slowly piecing it back together and trying to fix it up a little. It is a little too loud and uncomfortable to be a daily driver. I think the EFI will tone it down a little but I might need to change the cam or do something else. I'll probably down size the exhaust from 3 inch to 2.5 inch over the winter to see if that makes it better.

put me down for one of the thermostat housing adapters as well!

The one I got has the sensor sticking too far into the thermostat well, interfering with my hi-flow t-stat...

Just curious why you stuck with the throttle body type system here and didn't go with sequential/multi port like we've seen on your other projects?

Keeping it simple or...?

Are TB systems getting more precise?

That is an interesting question, I had to think for awhile on the answer. I guess it boils down to wanting to have actual hands on experience with as many different flavors of EFI as possible. I'm trying to develop some expertise on the subject and the only way to do that is to actually get my hands dirty with multiple installs and to tune different engines with different systems.

I think the Super Sniper is good enough for what I want to do with the Coronet but we'll see. I won't know unless I try.

I got the car fired up with the Super Sniper and took it for a drive. It runs better with the Sniper than it did with a carb that is for sure. Starts easier and warms up without having to pump the throttle or hold it at a higher speed.

I rolled into the throttle a little bit during the drive and the car just took off. Way more throttle response than the carb ever had. I think it is because the Sniper has 1:1 throttle linkage while carbs usually have a progressive linkage. That 1:1 linkage might be too much with an engine like this so I'll see if I can switch over to a progressive linkage.

The FITech has 1:1 linkage also... It took a little getting used to pulling away from a light without the car jumping on the converter.

I did notice my lean limit before I run into surge is leaner than the carb, and I attributed that to more uniform air and fuel distribution between the cylinders. But I haven't verified that with 8 WRO2s, haha.

I'm going to switch over to a progressive linkage. I think the 1:1 is unsafe on the street with a big engine. I did some data logging and at 4000 rpm I'm only at 25% throttle opening. 4000 rpm with a 512 inch engine is starting to make some noise and is really moving the car along so it is crazy that it is only 25% throttle opening. That means my street driving is confined to just a tiny bit of throttle travel. The 1:1 might work okay at the track but it is way too sensitive in my car for street driving.

Is the software compatible with a progressive throttle? You need to be able to tell it at what throttle position value the secondary blades come into play so it can fire the rear injectors and also to shut them off below that throttle position.

Yes, it will handle progressive linkage.

I've been doing some tuning today. The data logging feature is really nice. I took the car for a 20 minute drive around town and on the freeway and left the data logger on the whole time. That allowed me to look at a bunch of test points to see how the car is running. Everything looks pretty good except for AFR at idle. It was a little rich so I leaned it out and now we'll see how she runs.

Cold start up is really nice but hot start up isn't. Not sure if it is too rich at hot start up or what so I need to see if I can figure that out.

I think this setup would work pretty well on a 500 to 600 hp bracket car. The data logging would be a nice feature to have on most cars and the closed loop tuning would also be nice for a lot of cars.
