oh, see you at Buses No Where Near the Arches. About a 900 mile round trip for me. Looking forward to living dangerously.....again

[/quote]With the bodywork in such poor condition and those rediculously small wheels & much-too-low-profile tyres of probably wholly inadequate load rating, narrowed front suspension and inadequately supported engine, any British roadworthiness inspector, would probably order it off the road immediately, until ALL of those issues were properly addressed!

As it stands, it would infringe a whole host of construction and use regulations, potentiially resulting in a court appearance.[/quote]

2 parts to this:

1) the body condition tells the story and I am quite fond of the condition of it. The wheels are actually 15" which is larger than what stock was and the tires were what was available in my area during the pandemic, so I ran them. I prefer my bus going down the road than in a garage waiting for something. The suspension is something I have wanted for a long time and pretty excited about. And the last part of this first part. I DIDNT BUILD IT FOR YOU TO LIKE

2)I could give 2 shits about the inspection requirements where it is your are concerned about my bus violating. I don't live there, nor will I ever.

Suggestion: worry less, do more

Always the hate on here when its outside what you "all knowing Samba guru's" individually deem right. Seems to also always be followed up with awesome name calling like "ignorant jackass". However, between the 2 73's I have had this set up on I have traveled probably close to 30K. Over the Tetons and Big Horn, down to the Smokies and back. I always say the proof is in the results and your opinions are typically like diapers. No issues, no anger or discontent here....just awesome miles! lol love sharing on the old Samba. Have a great weekend and enjoy your dubs!

At very least wrap a chain under there in case they let loose

Any 72 and later bus is like this, sooooo, yeah if that's how you run your late bay you are hanging by a couple threads, lol

Here's a pic of what I'm talking about, found pic in gallery. I have seen those top ears broken off before.

So the whole weight of the engine & trans is hanging from the top 2 bell housing bolts! Yikes, don't hit any big bumps in the road.

[Sash_Bay]

Second bus doing this now, still running no mustache bar at all. No issues, no worries.

Keep cruising!!

In one of the appendices re car engine specifications & modifications, on Page 233 of his book, A. Graham Bell states the following about boring & stroking VW Type 1 & 3 style air-cooled engine:

A. Graham Bell, “Performance Tuning in Theory & Practice – Four Strokes”, Foulis Ltd – Haynes Publishing Group, Revised Edition, February 1988, ISBN 0-85429-275-6.

« Note: the 88 x 76 or 90•5 x 74 combination is the most reliable for road or rally use. The crankcase must be machined to accept 90•5 or 92 mm barrels. The weakness in the case can cause cracking behind No. 3 cylinder unless the case is carefully welded for additional strength. Engines using 78 or 82 mm cranks will require clearance machining of the piston skirts and crankcase; and the camshaft thrust shoulder must be re-radiused to clear No. 4 con-rod. For racing, Porsche rods should be used with 78 and 82 mm stroker cranks. Special cranks are available to suit these rods. »

74 mm stroke & 88 mm bore => 1800 cm³

74 mm stroke & 90•5 mm bore => 1904 cm³

76 mm stroke & 88 mm bore => 1849 cm³

76 mm stroke & 90•5 bore => 1956 cm³ [as offered by Afonso Motors in North Wales, UK]

The 2•1 litre water-boxer engine, with 76 mm stroke & 94 mm bore has a displacement of 2110 cm³. For the British market, this engine was rated at 112 horsepower, with a compression ratio of 10•5:1 using readily available 4-star, 97 RON petrol. For two-wheel drive vehicles, it was also matched using a 228 mm clutch to the factory-standard five-speed transmission (i.e. reverse plus 1st, 2nd, 3rd, 4th & 5th gears), which differs from the four-wheel drive Syncro vehicles which essentially have a four-speed transmission with a supplementary crawler gear for off-road use (i.e. reverse plus 0th, 1st, 2nd, 3rd & 4th gears).

True, stock 1600 won't be that fast. Last one I had was with ratio rockers, better exhaust and 36 webers. So I guess about 70 hp, similar to 2.0 type 4. But a big difference in oil temps, like I mentioned.
