    was thinking the same thing Gene!

    Get SVO engraved, or added on them somehow!

    I was planning on painting on the black stripe that's part of the original spat and rocker. I like the idea of adding a shadow SVO in that somewhere. I'll give that some thought.

    I was always thinking ....if you were to add side skirts, if there was a way to cut the section that says SVO out of the SN95 SVO side skirts and splice them into the ones for the fox body

    Here is an update:

    After installing the Cobra brakes up front, I took it for a test spin to bed in the brakes and test their braking power. Without changing anything else in the braking system, the brakes would work, but the pedal effort was very hard. In normal driving the brakes would work. In a panic stop, the pedal is heavy and hard and the rear brakes lock up to easy.

    I knew I was going to have to changes some additional components, but I wanted to verify the information on the internet for myself. After emailing with Maximum Motorsports, I purchased the 15/16" bore '93 Cobra master cylinder, the MM brake lines from the MC to prop valve, the wilwood proportioning valve, the prop valve plug, and a 94 V6 brake booster. I did purchase the rear Cobra brake calipers and brackets, but I have not installed them yet. I wanted to see if the wilwood proportioning valve would allow enough adjustment to keep the stock rear setup before installing the upgraded rears.

    I debated keeping the stock brake booster and machining down the MC, but in the end, I wanted a matching brake system. If you go with the '94 brake booster, you will need to elongate the mounting hole(s) as suggested on the internet, get new nuts to fit the smaller booster studs, and clearance the shock tower a lot. It took me and my brother a couple of hours with a 2 lb ball peen hammer to push the metal out of the way. I suppose the '93 Cobra booster would have been a better choice for ease of installation and being able to reuse the factory nuts. Even easier would have been to just machine down the'93 Cobra MC to fit the SVO booster. It would be interesting to know what the difference would be. I may choose this route for the NorCal car.

    I had to modify the MM prop valve to MC hard lines to make them work. The stock SVO prop valve has the same size tube nut in the front and rear locations, but the MM part has one that is 1 size smaller. To solve this, I bought a hard line from NAPA that had the correct fitting, cut it off, cut off the one that came with the MM part and installed the nut and flared the tube. I used my bench belt sander to just remove the existing flare on the new MM part to keep as much length as possible. It worked.

    After bench bleeding the MC, installing all of the components listed above and bleeding the brakes, I set the manual proportioning valve all the way out. According to the paper work, this setting allows 57% of the pressure to go to the rear brakes. In this configuration with Hawk blues up front and EBC yellow pads in the rears, the front wheels would lock and the rears did not. The instructions say to adjust the knob until the front and rears lock up at the same time and then back off just a bit. That's what I did and it took just 1 full turn of the knob to prevent the rears from locking up before the fronts. I will be going for a track day event at Barber 4/18 and will be able to verify this setting is correct under heavy braking conditions.

    With the '94 booster, '93 Cobra MC, and stated pads above, it will stand on its nose with only minimal effort. I am going to have to be a little more judicious with the pedal pressure than I was before. I don't think that is because I am getting more boost, but that the 13" rotors are providing more stopping power than the stock fronts.

    More to come...

    Just an update: Went to Barber Motorsport Park for a track event this weekend and put the new brake upgrade to the test. With the stock setup, i used to start braking at the #3 marker in the braking zone. With the new setup, I could easily wait until 1 or 1 1/2 marker to press the whow pedal. I had plenty of brake all day.

    This was the first time to run with my PIMP ECU in control. I was even able to due an auto tune session on track with the laptop strapped in. The first session I noticed a popping/backfire sound at 44K rpm. Looking at the tune, the fuel table had an abrupt change in values at a load factor I was not able to tune on the street. After the auto tune, it smoothed out. Probably can use some additional tweaking. I was running only 15 psi boost with the stock IC.

    All was going well until the engine died going into turn 13 going up hill. Was carrying enough speed to coast all the way into the paddock area. Once I stopped and cranked it, it started again. It did this a couple of times at the same place. Upon further investigation, I determined that my fuel pressure relay is going bad. Tried to get one from the local parts store and AZ and Advance both list the incorrect FP relay for the SVO. The correct one was found under the 87 Turbo Coupe at AutoZone, but it is special order. So if you don't have one in your spare parts kit, you may want to go online and order one. I got three.

    Given the amount of rain in AL last week, it was a good day all -in-all.

    After 29 years and well over 220K miles, my dizzy gear finally gave up the ghost. Looking at the gears, it looks like on one side of the gear, the teeth were still the proper width. On the other side, the teeth were worn thin and final gave out. So now I need to pull the engine to make sure the metal shavings are cleaned out of the oil pan before the reunion.

    Anybody have any suggestions on what I should look for as the cause for the uneven wear?

    from the issues I've heard / seen over the years, best bet is to replace the oil pump while it's out.
    it's not that expensive, and beats pulling the engine again.
