Is that an actual cobra throttle cable bracket? Can you take some close-up pics of it? I haven't actually ever seen one before and I'm gonna have to make one for mine...

It is.
Here are some pics of an actual Cobra throttle cable bracket on my actual Cobra.

Ported the upper intake for the Accufab TB.
The rest of the little parts that I've been waiting for should show up shortly, so I should be able to start bolting all of this together in the next day or so.
Then check my tune and prep for Carlisle.

From Accufab's web site:
The first throttle body is our standard ELLIPTICAL single blade which flows 1284 cfm compared to the stock twin blade design which flows 1089 cfm. Dyno tests on a stock vehicle show a 5 to 7 hp gain.

Covered my EGR extension tube with the HP Thermal Sleeving and a Cool Tube.
Because there's so many things at the rear of the intake now, I decided to move the DPFE sensor to the stock Cobra location and do away with the large stock bracket that holds both the DPFE sensor and the IMRC controller. I modified the Cobra DPFE bracket by removing everything below the DPFE sensor that usually holds the Cobra heat shield in place.
This meant that I had to extend the DPFE sensor hoses, so I used some more parts from the Cobra EGR tube that I used earlier along with some Dorman/HELP p/n 46019 hi-temp DPFE hoses.

So, I'm getting close to finishing, but there are still a few issues.
1. The '98 Cobra throttle cable is real close to being too short, and I've had to route it behind the intake, which I'm not very pleased with, so I've ordered a couple of later model Cobra cables to try. I'll probably have to custom make a cable bracket if I use a later model cable, but at least the later model cables aren't discontinued (yet!) like the '98 cable. I've looked into having a longer cable custom made, but it doesn't look like that's going to be practical.
2. The '98 Cobra cruise cable, which is the same length as the Gen 2 Mark VIII cable, is about 6 inches too short to reach. So I'll need to either relocate the cruise control servo or try another cable.
3. I can't get to the new junction that I created in the EGR tube behind the intake to tighten it. I'll probably have to remove the rest of the driver's side cowl to get to it.
The Vacuum harness was pretty simple. I used a new '98 Cobra vacuum harness that I had and spliced in the parts of the original vacuum harness that ran to the SAI vacuum solenoid by the Driver's shock and the SAI diverter valve by the crank snout.
So, I've got to solve the issues above and then reinstall the intake tube and refill/burp the coolant to finish.
Oh yeah, I've still got to cut the tab on the hood along with some other little things like the PCV tube and brake booster vacuum hose.

99-04 cruise cable is more than enough
I hope you're right, I've got one of those on the way too.

All together!
It's a little crowded around the Driver's side of the intake, looks like a Ford engineer designed it.
Time to download my tune, check for fuel leaks, and fire it up.
Still unresolved are the throttle and cruise cable issues, but those will have to wait until I receive the cables that I've ordered.

Started right up!
Idled fine, after the PCM caught up to the change in the tune. I raised the idle 50 RPM's to compensate for the IMRC removal. Probably not even necessary, but it's what I did on my Cobra years ago, can't hurt.
No leaks that I can either see or smell. I let it run until the fan came on.
After I let it cool, I'll check everything over one more time, then hook up my WBO2 and take a drive.

So how did I do against my original plans?
1. Figured that one out!
2. Only needed one fitting, for the Brake Booster Vacuum Hose.
3. Yup, so far, so good.
4. Also good.
5. FAIL! I still haven't arrived at a permanent solution.
:frown:6. Check. In case anyone's wondering, I couldn't bring myself to buy a new set of 24's (I was determined to replace the 13 year old injectors), I got the Gen III 30's at a good price, < $200, and it gives me headroom for the future.
7. You bet!
8. Yes sir!
So, all in all, pretty close to my plan.

Excellent! Power you will feel! That is precisely the throttle-body that I need.
