Great stuff...that small box at the top of the windscreen, is that a rear view camera??

Are the A/F ratios I'm seeing with carbs?? They appear to be acting like you have EFI...i.e. when you lift the ratios go lean. With my SU's, they go pig rich when I let off the gas. The rest of the time, they are similar to yours.

 

[MadMarx]

The box on top is the rear view camera instead of the mirror which only shows my helmet.

The A/F ratios are made with Weber carbs. If the throttle plates close then all flow is stopped and no fuel is supplied from the jets anymore. That's why it goes lean then.
SU's have a flexible choke so they always have flow and start banging to the exhaust.

Is that a stock tranny?

 

[arizonamike]

Great video. Thanks. I like that overdrive switch on the steering wheel.

 

[MadMarx]

Is that a stock tranny?

Stock housing with straight cut dogs.

Chris: Just showed this video to my 3 year old grandson. He asked me if Spider-man was driving. (red gloves). :lol:

 

[Monkeywrench]

How did the new motor perform?

 

[MadMarx]

Its not a new motor, just maintained motor with new equipment, like 48 Webers.

Cheers

Chris that looks like quite the busy track. When I first look at the speed, I thought, wait a minute no way can a race prepped TR4 do 165 mph on a straight, then it hit me, kilometers per hour, LOL. Cool video, thanks for sharing.

 

[MadMarx]

Especially for the inch side of the pond the dials remained mph and the digits are kph.

 

[arizonamike]

Chris, would you post more pictures of your car. You can hide the secret stuff.

What tires do you run?

How many speeds do you have, isn't that an overdrive box?

Oh yes...great driving too

 

[MadMarx]

I run on Yoko A048 205/60-15 tires.

you want more photos.....nothing easier that this:

Thanks Chris, that yellow TR3 can be had. Good luck.

I've been working on a brake set-up similar to yours, and have a few questions. On the dual master brake set-up are you using 5/8" bores on both? and did you change the mechanical advantage on the pedal? and, are the calipers stock or do you have calipers with a larger piston area? or, do you just have a booster hidden somewhere??

 

[MadMarx]

On the dual master brake set-up are you using 5/8" bores on both?

right 5/8" for both - from Girling. Front brake with tank extention.

and did you change the mechanical advantage on the pedal?

No, all stock. No changes.

and, are the calipers stock or do you have calipers with a larger piston area?

Front calipers stock, rear hydraulic between 0,75" - 1".
Currently I run 1"

or, do you just have a booster hidden somewhere??

No boosters.
Good brake pads are enough.
I run EBC YS.

Cheers
Chris

 

[martx-5]

Thanks. That helps me a lot.

 

[MadMarx]

Thanks. That helps me a lot.

Be warned:
1" rear brake hydraulics are close to the edge and need very sensitive adjustment!
My brake system was blocked by the sand on this track and look what happend in race 3:
