1970 San Francisco westfalia resto

[K@rlos]

3 days work and I’m at this stage, about 75% of the raptor is removed. Thankfully other than the jack point and small piece of the floors it’s still incredibly solid. It’s 54 yrs old and been here for 18, so I can’t be too sad really. Especially when you see the state many U.K. buses are in

For anyone who’s interested this is what I’ll be coating the underside of the bus with. Not cheap but kills rust, prevents new rust forming and cures as a primer. Got a 5 litre jug for the camper but I had this little tin kicking about.

Now I’ve heard of them but not that particular product. It does sound like it should be one of the better performers. Not even sure how I’ve heard of them? If it cures as a primer then even better I guess. How did you get to hear of it then ?

I stumbled across it last winter when I was doing some work on my beetle. Only used it on a couple of areas but was so impressed im going all out with it on the bus

the target is to have it all done for spring but we’ll see

Now all the scraping and grinding is done I made a start at laying some protection and paint on the under side at the back.



Epoxy mastic primer then a couple of good coats of paint. Not spike grade like deep shine but looks acceptable for an underside job out of a can lol.



Paint dried so proceeded so the fuel pumps and tidied up the wiring a bit.





Also had a nice nice parcel from America, new set of CNC ported 044 wedge ports with 44x37.5 valves & ‘big beef’ IDA manifolds from CB Performance

So you have two fuel pumps, how are they configurated? And those heads look great, the valves are huge

The Holley pump feeds the carbs via a matched Holley regulator set at 4psi, the other 1 is a Bosch high pressure fuel injection pump regulated down to 35psi which delivers the supplementary fuel for the nitrous system.

Went to the powder coaters next door this morning and got them to aqua blast my new inlet manifolds. The raw aluminium finish looks much nicer than the shiny finish CB sell them with.

Cut most of a crusty stuff out, just need to trim back a bit of the inner sill.



Hopefully start putting the new metal in tomorrow The repair panels from Alan Schofield are outstanding.



Cutting the belly pans off and will fit new which will be bolt on, so in future I can inspect behind there periodically and I suspect they have been hidden this for quite some time.

 

[K@rlos]

Belly pans totally removed, floor and chassis cleaned then given a healthy coat of hydrate 80

We cc’d the combustion chambers on the new heads Saturday. They came in at 67cc, need them at 57cc to achieve a 10:1 compression ratio. Will fly cut them at work in the next week or so.



Also made myself some solid mounts for the gearbox mid mount this afternoon as work was dead lol.

Interested to see this develop, both bodywork and motor

Another alteration/improvement I’ve been playing is this because since I’ve been using the nitrous in anger I’ve been suffering with wheel hop when leaving the line. I’d already fabricated a mid mount to make use of the ‘ears’ on my 091 based race box. After discussing it with Hector and Pete at cogbox we all agreed I need to tie the box in tighter to the chassis along with better shocks. So I got myself a CSP torque bar kit designed for a beetle and adapted it to work in a bus. Pete kindly gave me a laser cut bracket which he uses to fit 091 boxes in to bug race cars and I welded 2 of the tabs on it then another 2 onto pieces of 3mm plate before welding the plates to the inner faces of the chassis rails.



As you can see I’ve put it all together using an old case I use for mocking up. Preloading the torque bars in conjunction with the upper mid mount, and solid mounts throughout it is all now rock solid, no flex anywhere



Going to be a bit more noisy but I’d rather that than a broken gearbox
