Default Update

Spent some more time on my baby, finished rewiring the loom to the fuse box, got the right noises from the engine so very happy (these BF engines need alot of wiring!). Shortened steering gear is here, and installed. Have got my 200kg water container for the test, completed my preliminary test and I reckon its a good pass. So now to book the engineer for the test, hopefully in the next few weeks, four pot front brakes (from the three pot), build the steering shaft mount, get the engineer to sign off the seat/trans/engine/seatbelt mounts.

Sevenohms, If your retaining the jag rear brakes I would consider keeping the three pot fronts. Bigger isn't always best. Most Jag based Cobra's have next to no rear brakes as the front is over braked.
Some years back, a guy here with an RMC did some calcs and changed his 4 pot fronts to 3 pot. Can't recall if there was a master cyl change as well, i'm sure he runs a Falcon. He says it made a world of dfference.
I can see if he remembers or still has the info if you like.

Hi,

So after my joy at the torsional test, I got down to work on the turbo mountings. Tight fit on the drivers side, the passengers is good.

In regards to the brake performance, I have calculated the brakes from first principles, theres obviously a lot of variables to modify, but the main ones are pads and disc diameter, mc/slave sizes, the size of the tyre. One of the ones that can't be modified is how my car with a different weight split to I'd say most of the other replicas, with a Venom chassis and Ford engine, which carries and transfers its weight differently a "lightweight" Chev/302 with more of a ladder. I have the excel file if anyone wants it, its how I worked out which Wilwoods I wanted.

I would certainly be interested in your brake calculations. I will PM you my email address.

Cheers
