I have saw toothed belts on some drag motors so it can be done. Looking good Thomas.

Looks awesome mate.

Why don't people run a toothed belt like a timing belt on setups like this? Would be better at preventing slippage, if imagine that blower will be taking quite a bit of torque to spin.

Finished the belt setup finally. First I was going to weld on a aluminium bracket on the viscous mount(which is shortened), but it propably wouldn't hold for long without breaking. The stress of the serpentine belts are quite big. So I did the bracket of steel with a conical insertion to the alu mount. Added also an extra fitting point to the alternator bolt. The longest unsupported part of the belt is now 310mm.











Lets save the part numbers in this thread:

Pulley 8-rib INA 531 0721 10 (MB 1202000470)
Pulley INA 532 0289 10 (Fiat 9632722180)
Tensioner INA(Dayco) 534 0101 20 (Fiat 46546374)

Serpentine belt 6PK 1203
Serpentine belt 7PK 1290

Some testing and fitting with the tensioner, pulleys and belts. The longest non supported part of the belt is ~35cm, I may get it squeezed to 33cm by making a new fitting hole for the outer pulley. Hope the belt will not jump off easily. Got some belts for testing from a local auto parts store, and I changed the alternator belt to little bit longer than in the pic.

What do you mean des? Yes, I will remove the stock pump impeller, no need for it.


Yeah, my friend(tempo) also use this pump in his typ85 and it is great. Stock pump impeller and thermostat removed. Really nice when you can also set it for aftercooling.


Sure, I'm aware of that.


Alex, I propably will use the Davies Craig lcd controller. It's so simpple to use and set up, and works without issues.

That explains it well thanks.

What way will you connect the pump? Remove impeller from stock pump?

You will like that water pump. I installed one on a Lotus V8 tt Esprit for a friend. It was the only thing that would keep the engine cool enough to last a 45 minute session without overheating.

S4 glasses, corners, hood and wings are different from s6.

Hey Thomas, are you going to use a PWM module on the Maxx ECU to control the water pump?
I was thinking of doing the same

A6 glasses... Are you sure?

Looks pretty close to me. Same Hella brand and part numbers as orginal glasses.




Got a small package again today. Davies Craig EWP150 water pump and controller kit.
