Blizzard's rolling rebuild of a 1303 1975

[Blizzard]

Used my CAD skills to make a Rear Engine Tin to fit the Porsche-Style Cooling.

Cardbord And Duct tape.





The bolts will replaced and I will make a better looking one out of thicker aluminium.

I made this very quick so I could drive the car.

Sweet CAD!

Looks like an awesome engine, hope it all goes well!

Thanks!!

This BAS Porsche 911 style cooling shroud is modeled after an original 911 fan shroud. Knowing this I wanted to try and install the alternator air deflector.





The aftermarked alternator in the 240mm. fanhousing sticks out 1 cm. more out of the back compared to an original 911 alternator. I had to cut some material from the fiberglass cone around the mouting points and trim the vanes a few mm. but now it fits perfectly



I used two M6 10mm. nuts the first to hold the cone in place and the second to lock the first one in its place. I've done this not to overtighten and crack the cone. Ebay is full of those.

I also made a modification to the cylinder tins. The credit for this idea goes to the engine builder of Skywalker's Type-4 in his Splitwindow bus.



With a Type-1 style or 911 style shroud the air now comes from the top instead of from the back like on an original type-4. With this mod air is guided around the heads towards all 4 exhaust ports. The original tins only have this at the number 4 cylinder. The number 4 cylinder already gets the least amount of air with a 911 style cooling ( The air has to make a S shape from the back of the fan to flow between the shroud and number 4 cylinder / head . Flowing air takes the path of least resistance. So without this mod the cylinder that gets the least amount of air flow is also the only one with a more restricted path for the airflow, The path of least resistance
are the gaps between cylinder 3 and 1 and the shroud, alot of air is lost without cooling anything.

And After modification





With this mod all the air is forced through the cooling fins off the cylinders and heads.

And in my case the most important ( piece of mind ) upgrade.

Swivel-ball to swivel feet valve adjustment screws.



And yes I checked that all the feet can move without touching the rockers.
