Hello and welcome back to Stage 3 of AmericanMuscle’s project Foxbody, as you can see we’re currently out enjoying the fruits of our labor which took place in the first two stages, and for the first time since we started this project, I can honestly say I’m not embarrassed to be out driving it. Of course a part of that lack of embarrassment is because we haven’t pulled up to anything fast yet, there’s no doubt our GT is looking good, but what’s the point of having all those Cobra parts if we don’t have the performance to back it all up, well, welcome to stage 3 my friends, where all of that is about to change. Before we get back to the shop where we lay out our plans to increase our tire slaying abilities, let’s recap what we knocked out in stage 2. In stage 2 we completely replaced our destroyed factory convertible top, with a brand new top and rear glass, along with just about every piece of molding and weather stripping you can think of, we put the finishing touches on our convertible Cobra vision, thanks to our Cobra tail light covers and 10th anniversary Cobra style wheels, made possible through the 5 lug conversion kit we installed. Finally, we moved to the interior and made it look as good as our exterior, thanks to the freshly painted dash, new carpet, and other miscellaneous items making our GT look and feel like it was 1993 all over again. Alright, I can’t wait to get back to the shop to show you all the stuff we have in store for this stage, let’s get to it. As you can see we have some big plans for our 302, all with the goal of replicating the Cobra’s power plant, which is going to drastically improve our performance. For starters, we’re going big with a trio of parts from Ford Racing, all of which will do wonders for our 5.0. First up we’re looking at the Turbo Swirl GT40X aluminum heads from Ford Racing, these heads are a variation on the original GT40 heads found on the 93 Cobra, with a few improvements. For one they’re made out of lightweight aluminum versus the heavier cast iron and they’re designed to flow much better than the original GT40’s. To top it off, we’ve installed some Cobra valve covers. For us to see the biggest gains using these heads, our stock cam just isn’t going to cut it, so we’re going to go with a popular street cam, the Ford Racing E303. This hydraulic roller cam should really compliment those GT40’s, and is an excellent choice for any street car thanks to its low to mid range torque. Of course we’re still going to have that great lope at idle which should sound amazing by the way, but it’s not radical enough that we’re going to have to worry about stalling out at every red light. The cheery on top for our 302 has to be this Ford Racing intake manifold, which is getting nearly impossible to find anymore, this part, paired with our Ford Racing heads and cam, is going to allow our 5.0 to flow some serious air, and will complete our Cobra transformation under the hood. Alright, in order to move all that extra air out of the engine, we’re reworking out entire exhaust from the headers all the way back, in order to keep up with that Ford Racing theme we’ve got going on under the hood, we selected our ceramic shorty headers, which we’d already installed when we did all of our motor work, and are designed to work specifically with those GT40 heads. From there, we go to BBK’s off road H pipe which does feature mandrel bent 2.5” stainless steel tubing, and should bolt up to those shorty headers without issue. Finally, everything’s going to exit out of Flowmaster’s American Thunder Cat-Back exhaust, which features those iconic 44 series mufflers. This exhaust features 100% stainless steel constructions throughout, including 2.5” mandrel bent tubing, and those OE style polished tips. Alright I think it’s safe to say we’ve got the performance side of things pretty well taken care of, but we haven’t addressed the fact that this thing still handles like a boat. So we’re going to attack our suspension much like we did our engine, go big or go home. Ron and I are just finishing up installing the KONI STR shocks and struts, which are actually a killer set for the price. We’re pairing those up with the SR Performance lowering springs, which should lower our Fox about an inch and a half on all 4 corners. Finally, we have the car in the air, the wheels off, we figured this would be a great time to ditch those rusty old drum brakes, in favor of these brand new disks. To dial in our new Fox’s alignment, we’ve installed the SR Performance caster/camber plates, which should get everything back into spec without issue, and offer a little bit more adjustment in future if need be. Since our car is a convertible, we are losing some of the structural rigidity which comes along with having a steel roof, to help combat this, we’ve installed the SR Performance subframe connectors, this part along with our springs, shocks and struts, should take all the laziness out of our suspension, and get it handling like a sports car should. Alright, now everything’s pretty much buttoned up, we’re going to tie it together with one of our custom Bama tunes, and see if all this hard work has paid off in really cranking up the power. We’ve already grabbed our baseline run after stage 1 when we got the car back from painting, so I’m going to hop in, bury this thing one more time, and see what the improvements are. Alright, our baseline run with our 93 GT gave us 194 horsepower, and 266 ft/lbs of torque. With all of our stage 3 modifications, the car put down an impressive 279 horsepower, and 317 ft/lbs of torque, making for a solid gain of 85 horsepower over our baseline numbers. The car did even better throughout the power band, picking up as much as 103 horsepower, and 107 ft/lbs of torque, throughout the curve. With the power finally there to back up our Cobra appearance, I think it’s time for one more cruise to see how our Fox does with all its modifications. Alright, stage 3, performance, check. The car's breathing better, the tune brought it all together, and as a result, this thing has some serious balls. Here we are, we’re in the back roads, moving along at a good clip, I’d saying the car is doing quite well, it’s pretty confident, I feel confident driving it, I don’t feel like I’m going to fly off the road, which I couldn’t have said before we did all this work. The car feels good, sounds awesome, and it’s just a whole hell of a lot more fun to drive. I know some people might question this build, you know, why a convertible, why a Fox body, well, because we wanted to, I mean that’s what car building is all about, it’s doing what you want. In this case, we’ve never seen Cobra convertible Fox bodies, so we wanted to build one, and I think we did a hell of a job. So is this the last you’ve seen of this car? I don’t know, maybe, maybe not, but in the meantime, thanks for watching stage 3 of AmericanMuscle’s project Fox body.

Bama will not tune
I liked them at first, but apparently bama chips do not work with them, luckily I installed a tuned bbk MAF, though I will have to change that out too because it will not take a tune either. I will admit I have issues with the wiring harness, but it has never given me issues, and the fact that it ran good before makes bama think it's theseHelpful (3)

Accel 24#ev1 injecter install
Mid and high end torque improvement. You can really feel it on the highway. Love-em! I have a 78 mm throttle body, underdrive pullies and a free flowing exhaust. I had one of my original ones go bad and decided to change them all.Helpful (6)

Bama won't let me
I hear good things of these injectors and was very excited to install while waiting for my new tune from bama, I received an email from them saying they have had many complaints and problems with these injectors so many that in fact they will not write me a tune for my car while I have these just a heads up probably great for 80's but bama won't write a tune so if you have a custom tune go with Ford racing ev6 save yourself the stressHelpful (21)
will the stock 1998 mass airflow sensor be able to handle these i have a 98gt with mac long tube headers,O/R pro chamber mid pipe, 70 mm throttle body, cai, upper intake plenum msd coil packs and ford racing wires. i notice in my data logging that I'm running lean . i figure the next step is to move up to 24 pound injectors i just dont know if i need a bigger maf if so, what size?
You stock MAF would be able to handle that injector upgrade easily. You would need a new tune, but the stock MAF will work just fine.
Could these run e85?
The Accel High Performance EV1 Fuel Injectors are E85 compatible. Keep in mind, a larger injector is required to run E85 than gasoline, so if your car uses 24 Lb/Hr injectors when running gasoline, these will most likely be too small for E85.
Do u need a bigger fuel pump like a 155
You do not need a bigger fuel pump to run these injectors.
I purchased these and they are great. My car has been falling on its face and running horrible at higher rpms. Misfiring and popping. I think it’s fine for a A tune will these work with a mega squirt gen 2 with wide band ?
I don’t see a CARB EO#. I’m guessing they’re not CARB compliant?
This part is legal for sale and use on Emissions Controlled Vehicles.
Many other tune providers can write tunes for these injectors, and as not all customers use Bama, we provide this as a additional option.
The physical volume of fuel these can supply is the same as OEM on the Cobra, however, the voltage slopes and other factors will differ from the OEM injectors. A tune would not be required but would be highly recommended to ensure smooth operation.
Your stock injectors and MAF would still be ideal for your Mustangs build. You can definitely upgrade the MAF for an improvement in performance. However, we usually do not recommend upgrading the injectors until you are running E85 or are running a supercharger/turbo with your build.
A tune would not be required but would be highly recommended to ensure smooth operation. The physical volume of fuel these can supply is the same as OEM on the Cobra, however the voltage slopes and other factors will differ from the OEM injectors.
Yes, The Accel High Performance EV1 Fuel Injectors will indeed work well with an aftermarket fuel rail unless the fuel rail states otherwise.
The injectors will fit in the factory fuel rails without any issues, a fuel connector adapter may be needed, however, depending on what year vehicle you have.
300 horspower at the crank should be well within the power handling capabilities of the OEM 19Lb injectors on your car. We would recommend looking into the tune to see if fuel pressure and fuel tables are correct in this situation, as this power number should be easily handled with your current injectors, and the next step up would drop injector duty cycle to around 70% which is lower than what is preferred.
