My Hydroboost barely clears the engine. Due to the exceptional width of the Coyote, Hydrotech engineered a cantilever, which raised the Hydroboost 2.5.” I have a stock firewall using a stock pedal box. Pictured is the Wilwood Tandem master cylinder #260-13190. I’m confident revisions will be ongoing.
Pictured is a late model GM style “Street Preparation” Hydroboost. It’s my understanding that Wilwood master cylinders are only available in the GM bolt pattern. Because of the cantilever, Hydroboost recommended going with a 1” bore master cylinder as opposed to a 1 1/8” bore.
I will most likely need to need to chop the driver side engine coil cover (not installed). I may need to create a support bracket to reinforce the lengthy rig and possibly swap to a different tandem master cylinder as I figure out a workable dipstick solution.
Distance from interior firewall to brake pedal rod is currently set to 5 ˝” to match the clutch resting pedal height.

I am using Banjo -6 AN fittings. High-pressure hoses are Aeroquip Teflon and low pressure, Aeroquip starlight hose.
Routed power steering lines and joined the two low-pressure returns under the radiator. The radiator has a power steering cooler which then returns to the power steering reservoir.

This is the engine bay in its current form. I still need to finish the mass air, CMCV vacuum, and make a few other refinements. Amazing to think I couldn’t tell the difference between AN and NPT fittings when I started on this endeavor. Oh, now that I have a better idea of how much space that I have, its time to install the clutch!
