1969 Mustang BOSS 302.0: DSE Suspension, 5.0, V8TV Build

[AUTODYNAMICS]

Very cool

[oestek]

You couldn't have started this project at a better time. My father has a '70 boss 302 and he has been asking me what kind of suspension mods are out there that people are doing. He wants to keep it mostly original except for the suspension. I'll def be pointing him in this direction.

Very much looking forward to seeing future updates,

Hope this thread helps!

Never seen anyone mask with aluminum foil. Not a bad idea!

The motor looks sweet!! Keep up the good work!

The foil is a trick we use when you have a super-complex shape to mask. Works well!

Here's the intro video on the BOSS 302.0.

In this video, we extract the car from the barn, and go over the plan and design concepts for the car.

Here's the video install of the Detroit Speed Aluma-Frame and front suspension system. Some of the holes are a little tricky to drill, but overall, the install went smoothly. Can't wait to drive this one!

Correct, they use an electric motor on the steering column and a manual rack. Flaming River is making such an animal, which seems to be based on the Ford system, but we are using the DSE rack. We also require the pump for the Hydratech hydraulic assist brake booster.

Flaming River unit:

The new mustang uses an electric motor mounted on the rack housing to provide assist torque which is called a REPS system (Rack Electric Power Steering). The unit in the picture is a column mounted EPS system (CEPS). EPS stands for electric power steering. Usually vehicles heavier than 3500 lbs or high performance vehicles use a REPS system due to the high loads that would be seen in the system. Also, REPS allows for more feedback at the handwheel, which is more desireable in a high performance vehicle. With a CEPS unit, the intermediate shaft going from the column to the rack sees full assist torque and needs to be beefed up. With a REPS system or a hydraulic power steering system, the intermediate shaft only sees hand wheel torque. I don't know much about the system you have selected, but I do have experience in electric power steering and I'm not sure you will like the feedback or lack thereof you will see with a column mounted system. Not to take away from this build, just wanted to make sure you will have the correct parts/expectation from that system. A vehicle like the chevy sonic has a CEPS system.

Neat Kevin. This DSE system looks like something totally different from everything else out there for early Mustangs. I'll be curious to get your driving impressions once it's done.

Any idea of what these systems go for?

We're not using either of these, I just forwarded the info along because someone asked. We're using the DSE rack and a Type II steering pump mounted to the Coyote with the Vintage Air Frontrunner accessory drive system, a traditional power steering setup.

Here's the first part of the Detroit Speed QUADRALink install, this is the deep tub and brackets that go on the car's body.

Flaming River unit:

As an informational aside, American Powertrain has a column EPAS deal similar to the Flaming River part, at like 40% of the flaming river cost. A compadre in OZ is using one in a wide-tired MGC, and he reports little compromise in road feel and feedback. Basedon his inpit, thinking I may go that way also.

Here is the company that makes the units for Flaming river, they have several other options.

The customer had us put this project on hold, but now it's back in line for action.
