I'm a little late on this update but we have a brake and carb solution!

 

First the brakes. Obviously the stock drum brakes were not going to hold up for much longer, especially with all this added power. We choose to go to 4 wheel disc brakes using Wilwoods Forged Dynapro big brake kit. We are using 6 piston front and 4 piston rear calipers. The rear even has parking brakes! 

Since we changed from drums to discs we also had to replace the stock master cylinder. We used an Wilwood aluminum master cylinder with a proportioning valve. We also added stainless steel front brake lines. 

 

 

All the new Wilwood parts laid out.

Here is the front rotor and hub assembled

The front assembled on the car with the massive 6 piston caliper!

Assembling the rear brakes. The kit requires a different bearing retainer. The old one was cut off and the new one slipped between the bearing and wheel mount flange. 

The rear assembled on the axle before the caliper and rotor were mounted.

The rear all finsihed up (minus the parking brake). We did have to remake the hard line on the axle to allow for the new placement of the caliper. 

New vs. old master cylinders

Unfortunately, the proportioning valve bracket would not fit the car without interfering with the clutch linkage so we had to relocate it in the engine bay.

Here is the simple bracket made up to mount the proportionating valve.

Our carb solution was simple, go to fuel injection. We bought a Holley sniper EFI Stealth 4500. This system should work with our Torquestorm supercharger. This did require running another fuel line for the return system, a new fuel pump, and with all that changing we decided just to add a fuel cell to the car. 

 

Here is what was included in the Holley Sniper kit

For the fuel pump we once again choose Holley. This is a drop in tank fuel pump using a Walbro 255 fuel pump. It replcaes the fuel cells filler cap.

Here is the fuel cell mounted in the car. It's a 15 gallon tank from RCI. it even came with a sending unit! Unfortunately when the tank is filled with foam, the sender doesn't work too well. 

So much for an un0-cut rear floor, but we had to fill it up somehow. We cut the floor large enough so that we can remove the pump from in the car. This came in handy when the stock pump failed after a mile. Fourtuntly Holley replaced the pump for us. 

Here are the fabricated fuel cell mounting straps. We will be adding rubber to fit between the straps and the tank.

Here is the Holley mounted in the car. We were amazed at how easy everything was. The kit has a screen that sits in the interior. We followed the simple instructions for wiring and setting everything up on the screen and the car fired right up. It is a self learning tuning system as the car is driving but even the base tune seemed to run quite well. 

Picture of said screen.

If you rememberer back we had an issue with a high RPM fuel starving issue using the home made blow through carb setup. This problem disappeared with the Holley kit. The car has been running quite well with the EFI. Our next steps are to dyno it as is and then build the engine up a little more.

Now for the weights!

Stock front discs

Wilwood fronts (missing brake pads)

 

Stock Rears

Wilwood Rears

Stock master cylinder

Wildwood Master cylinder and proportioning valve 

Our past experience with disc brake conversions added weight to the car, We were very happy to see some weight come off the car with this modification.
