2003 Mustang Cobra convertible getting e-level setup!

Thanks for the compliments, guys, I'm glad you're enjoying it.

Last night I did a little bit of work on the Cobra. I had several small things to take care of , so I was only in the garage for about an hour.

First up, I installed a new serpentine belt and idler pulleys from Billetflow to resolve a belt slippage issue that I was just beginning to have. The stock idlers tend to eventually self-detonate, so that can be considered preventive maintenance.

Next, I got a "Service Engine Soon" light last week while driving in the rain. I suspect it was caused by the rain, so I just disconnected the battery to clear it. If it comes back, I'll look into it further. Baby steps!

And finally, most relevant to this thread, I removed the air tank to drain the water from it. There was probably between one and two cups of water in there, so I'm glad I did it. In the spring and fall, the nights get below freezing around here and I didn't want my car to be incapacitated again like it was once this spring.

Needless to say, removing the tank to drain the water is not very practical, so Michel and I brainstormed a bit to come up with a plan for a water drain from the tank. The tricky part is accessibility, and the fact that I want the water to drain outside the car and not inside the trunk. We came up with a rough plan but I'll have to go to the local air compressor supply store to see just what options I have on hand. I'm hoping to get this done before I go back to work on Wednesday this week.

In other news, I've been on the hunt for a new (to me) winter car for weeks now, and I may have found an interesting candidate.

That's It for now!

This morning I made the trek down to Billet Pro Shop. They're a new name on the scene, mostly for short shifters and Mustang parts, but I've known Sylvain for several years. His street driver is a 10-second GT500, and his track cars are even more awesome. His daily clientele is a long list of 700-1000 hp Mustangs, but for some reason he really likes my Cobra as well.

I went down there thinking I'd be in the shop for several hours. I wanted to have them see if they could work on my exhaust system to get more ground clearance. As it was, the cats would sit on the ground when aired out. On a Mustang, the exhaust is the lowest part, and mine has been getting abused for several years now. The Bassani high-flow cats were flat on the bottom, the mufflers are all bent and scraped, and most of the rear hangers showed signs of having touched the ground. I had purchased a pair of used Bassani cats from another forum to swap onto the car because I thought one of mine was getting clogged.

Once we got the old cats off the car, we immediately noticed that the new ones had a more compact body. They would fit, and being 3/4 inch smaller in diameter than the old ones at their biggest point, we instantly resolved the ground clearance issue as well! We readjusted the fit of the complete exhaust system to get things lined up a little better and keep it tucked up under the car, but it was easier than I thought it would be.

While we were under the car, I noticed that the rear shocks were working their way off their lower mounting bolts. The inner sleeve of the bushing was still in place but the rubber bushing itself was working its way over the head of the bolt. We removed the bolts, put big fat washers on them and reinstalled them. Problem solved! I figure this was happening because all the weight of the car is sitting on the shocks when it's aired out. Fixing this also eliminated one of the annoying noises I was hearing in the rear suspension.

Sylvain is really passionate about Mustang performance, so we chatted for a bit about what he's up to and what kind of work he does. He has access to a CNC machine, so the sky is the limit when it comes to machining stuff. It turns out that he would be able to port my blower for a reasonable price... He's also got a sweet connection for parts inside Ford Racing, so I asked him to get me a price on a set of 3.73 rear gears installed. Maybe next year I'll undertake one or both of these projects. Time will tell...

I put the Cobra away for the winter last week. It's time to evaluate what needs to be done in the off-season.

The big news is that I just ordered Accuair's iLevel controller. I'm hoping to have it under the Christmas tree because it's a partial gift from my girlfriend. Every guy dreams that his girlfriend would buy him something really cool for his car, and now I'm one of those guys whose dream will come true. Of course there's no hurry to get my hands on it because the car is stored off-site and I won't be able to install it until the spring anyway. In the meantime I'll get informed about what iPhone I want to buy. Surely an iPhone 5.

Since around the time I took my car to Billet Pro Shop and had it up on the lift, I've been having problems with the ride height on the rear suspension. When set on preset 2, it airs out completely regardless of whether it is at the right height or not. I'm thinking one or both of the sensors may have suffered some damage from being on the lift. I am NOT blaming Billet Pro Shop for this. In the spring I will swap the rear height sensors to the front of the car and the fronts to the rear and see what happens. If the rear still airs out, then I guess the problem is inside the ECU. I tried redoing the automatic ride height programming and setting the height presets manually, but that didn't help. I'm hoping that Accuair will be able to help me out in resolving this problem. I don't care to spend $500 for a new ECU if this one is on the fritz.

I'm also mulling over a couple of other possible projects that will require investing a fair sum of money into the car. Not sure I want to proceed on either one at the moment, but if the mood strikes me, I may pull the trigger.

First is a possible upgrade to either one or two Air Zenith OB2 compressors from my current dual Viair 400C's. This doesn't require a whole lot of preparation, but those OB2's are quite pricey. I may also bump my system up from the current 150 psi to 200 psi when I make the switch.

The next project is not suspension related, but a comprehensive power upgrade which would net me another 40-60 rwhp. I'm looking into supporting modifications at the moment which would be required for a blower upgrade. Not so much a blower upgrade, but having the stock blower ported. Billet Pro Shop is getting their feet wet in the blower porting business, so that's the route I would take. A blower upgrade on these Cobras usually requires a Kenne Bell Boost-a-Pump and a SCT BA2600 Mass Air Flow Meter to be able to cope with the big increase in airflow that the ported blower can provide. Both of these upgrades are not terribly complicated on their own, but when you get into extensive mods like this, the potential for trouble rises exponentially. This would also be my first foray beyond simple bolt-ons. I am trying to evaluate the risk vs. reward aspect, which isn't easy because of the abundance of information about these upgrades on these Cobras. I've got all winter to work on it and collect the required parts. The engine's ECM would also require fairly extensive retuning to get everything working in symphony.

I've also been considering a swap from 3.55:1 to 3.73:1 rear axle gearing. It doesn't sound like a huge change on paper, but I feel it would be enough to make a difference in the car's performance without sacrificing its daily driveability. I drive the car regularly so any shorter gearing (higher numerically) would result in higher RPM's on the highway and I don't want that. Slightly shorter gearing would give me a little more punch off the line, and the added bonus of slower low-speed rolling in first gear for traffic purposes. As it is, idling in first gear is actually too fast for the goddamn slow traffic we get around here. I constantly have to drag the brakes and/or clutch in to keep from catching up to the traffic ahead. Sounds silly, I know, but that's what it is.

So there it is, my winter to-do list.

changing the gear is the bomb ... im planning on goin 3.90 or 4.10 on mine but im not supercharged
 
It's been a while since the last major update. Mainly because the Cobra has been working well, so there just hasn't been much to report on. I also bought a house over the winter, so now I have my own garage in which I can work on and park the car!



One issue I was having last summer was an error for the left rear ride height sensor on the eLevel system. I just didn't have time to check it out, but the air system was still working well. Just when one of the sensors bug, the preset heights don't work, but the height adjustability is still fully functional.

This weekend I finally brought my toolbox home from my friend's garage, so I was able to pull the left rear wheel off the car to check out the sensor problem. I don't know how it happened, but the sensor's swingarm got bent in two places, and the mounting tab on the upper upper A-arm was also bent. The pushrod had become disconnected from the upper A-arm, so the sensor wasn't reading the actual height of the left rear corner. Instead, the sensor was just flopping around and giving erroneous data to the ECU, so the ECU would adjust the air pressure randomly based on those false readings.


Right now I'm in the process of contacting Accuair about what I can do to fix this. They've suggested that I could just bend the swingarm straight again and I should be OK. It's a free fix, so I'll give that a shot next weekend when I get back home.


In other news, since I got the car back on the road this spring, I've been driving it lower than I did in the past. Strangely, I didn't bottom out nearly as much as I was expecting. I have noticed, though, that the rear shocks are on their last legs. The to-do list never ends...
 
Vraiement cool comme setup... mais un gros gaspillage sur une voiture qui est fait pour prendre des courbes et de la vitesse.
 
ostie qu'elle est belle

Thanks for the compliments, guys! The K-member is stock, and the K-member brace that convertibles come with is also stock. There's less ground clearance to begin with on a convertible than on a coupe. I don't have a pic of ride height at the moment, but I'd say there's less than 2" under the K and mufflers, and about 1" of tire-fender gap.

Here you go, this is roughly my ride height lately. Until I get the sensor issue fixed, the presets don't work so ride height varies a bit day to day.



And just because I "can":

vraiment beau ton cobra, mais c'est quoi le turn signal package ?

C'est un espece de levier qu'ils installent derriere le volant, et quand tu le pousses vers le haut ou vers le bas, il fait allumer des lumieres clignotantes sur l'exterieur de l'auto. Cela a pour but d'indiquer au monde tes intentions lorsque tu conduis. C'est tres pratique et securitaire!
 
not bad for the height ...

this week ill be putting bigger tire on mine .... and raise the front just a little bit

Sur une mustang tu a comme 3 ampoules par coté sur les beam arriere. Je crois que le module fait en sorte que quand tu flash, les 3 lumiere alterne du centre vers l'extérieur

Genre ca
