Vintage Fords on VSCC Welsh Trial 2017
I thought I'd share this video from SimonLewsBooks on YouTube.
Various Model A's tackling the trial course! https://www.youtube.com/watch?v=JSDQ4BcIiWc&t=44s

Re: Vintage Fords on VSCC Welsh Trial 2017
By the sound of the motors they are all the UK under-powered version?

Re: Vintage Fords on VSCC Welsh Trial 2017
As John rightly says the majority of A's over here have the larger engine as they are imports, including mine. As for Brexit we've got about as much idea as our government which = 0

I chose a Stromberg from a 1950's Holden. The Holden motor was about 2.3 litres and revved to about 5K 2.3x 5000= 11,500. The Model A motor is 3.3 litres and revs to say, 3,000 rpm. 3.3x 3000=9,900. The Holden carby was PLENTY big enough but not so over sized that the lower end of the rev range was compromised. Many people use a carby that is too large and spoil the "driveability" of the car It's a quick and simple way to determine whether a carby is suited to a different motor.

Re: Vintage Fords on VSCC Welsh Trial 2017
You've peaked my interest So would that Holden be a six similar to the Chevy Stovebolt or even a Vauxhall over here?

Perhaps a pair of MGB SU carbs would be enough. 1.8 x 5000 comes to 9000, which should work fine. |

Re: Vintage Fords on VSCC Welsh Trial 2017
Never heard of a Chev Stovebolt but I think the Vauxhalls were similar. They were a 2.3 litre six cylinder OHV motor used by Holden from 1948 till about 1963. Being a GM product, I wouldn't be surprised if the Stovebolt was very similar.

Perhaps a member who has competed in a Model A could confirm that, maybe Jim Brierly?

Re: Vintage Fords on VSCC Welsh Trial 2017
" ... I have noticed that problem when people have fitted a weber progressive 2 barrel carb to their MGB. They fall flat until RPM is at mid range."
Maybe the intake manifold is too big? I thought the idea of the side draught was to remove the bends in the intake manifold and make it more responsive. My understanding, from nowhere in particular, was that the Holden 6 was just a variation of the Chevy 6 (stovebolt?) from the late 20's. However, the font of all knowledge Wikipedia, says: " The engine was based on a Buick pre-World War II design, and saw only minor changes throughout its 15-year life." https://en.wikipedia.org/wiki/Holden_straight-six_motor An advert from 1964 with the new redesigned "red" engine: https://www.uniquecarsandparts.com.a...Red_Motor.webm |

Re: Vintage Fords on VSCC Welsh Trial 2017
I thought it was a fun video and would have no idea on how to drive my car in the mud. But, I assume all of the bouncing was to gain traction-or just for fun.

Re: Vintage Fords on VSCC Welsh Trial 2017
If the bouncing is correctly synchronised it helps traction a lot, also the tires are generally dropped to about 12 psi ;glue on the rims helps the tire from slipping round. All good ( but not clean!) fun

Re: Vintage Fords on VSCC Welsh Trial 2017
John is quite correct about bouncing to aid traction but bouncing also slows the car down so a delicate balance is needed to achieve forward motion and speed. After many years of trialing I realise its a black art perfected by few but enjoyed by many, certainly the greatest fun available on four wheels and includes all the family if they willing to get down dirty on a wet weekend.
Picture attached of last weekend's fun in The Lake District. |

Re: Vintage Fords on VSCC Welsh Trial 2017
Hi Nosbod
How do you set the cars up spring/shocker wise or is it all standard stuff? Cheers Kevin

Re: Vintage Fords on VSCC Welsh Trial 2017
Hi Kevin,
There are basically two classes, standard and modified. I run in the standard long wheelbase class which allows no changes from original including tyre and wheel sizes, engine suspension etc. This class is virtually a Model A benefit which is a great challenge as only 27 points covered the whole class last weekend on The Lakes. the green Phaeton next to mine is modified so can leave off the bumpers, use bigger tyres, tune the engine and add ballast etc. This for me is not the spirit of the event but its whatever turns you on. Long may it continue! John |
