I just shortened the joggle to 1" offset. Should be o.k. now for a panic no-boost stop!!! Thanks for the demonstration.

Yours looks better than mine but what I put together works o.k. in my '48 Custom 8. I don't have a lot of wrap on the alternator but I've loaded it to 100 amps without slippage.

I fabricated the stepped link between the brake lever and the booster. It works but would look better if I just joggled the pushrod. (Fabricating a new engine mount would allow moving the booster up so a straight rod would work fine, also.)

I used to drive a Citroen. The DS had a power brake system that relied on hydraulic pressure (engine driven hydraulic pump) for stopping. They had an accumulator capacity to allow for 10 panic braking stops from 60 MPH with no pressure from the engine driven pump. It was safe...but I still had doubts.

This photo shows the sheet metal protection for the system.

I think you're right. I'm only marginally happy with my location but at least I have some high-strength tinfoil to protect the installation. The original sheet metal splash will give some water protection.

The booster is 'out of sight' right now. I thought hanging it on the firewall would be very unsightly. Of course the AC compressor on top of the engine is sort of a red flag that the setup is not exactly original.

P/N's from Pirate Jack:
PB7537 Dual Booster
MC1322H Master Cylinder (4 Port)
PV2K-1BM Proportional Valve

10 lb front and 2 lb rear residual valves installed in the respective lines. Used Eastman flaring tool...easy.

The 4 port Master Cylinder allows installation of a hydraulic brake light switch. Also...the folks at Pirate Jack are very helpful.

Not as much wrap-around on the alternator pulley as I would have liked but I tested it at 100 amps load with NO slippage observed.

This was a test installation with an original radiator. The overflow dumped into a 24 ounce plastic container.

Attached is a photo of the belt as it was installed while the engine was being assembled.

Here are some photos of the installation. I measure a little over 8" between the pan flange and the frame.
