Mostly Thruxton with some Castle Combe and Abingdon. All depends what's going on at work etc. I went to Spa in my R56 last year and loved that... but would like to take this car to the nordschleife if I can persuade the Mrs she want a road tip LOL. My only concern is with the choice of FD as I suspect at the ring I will be spending a lot of time on the rev limiter :D

Another month, another update. The shell left rust repair and headed out for the safety cage. Today I went in for fitting and took a few progress pic to share:

reminds me we'll need to remove the sound deadening from the roof before paint:

Finally!!! Today I collected the shell from having the cage fitted; next step dry build & paint.

I decided to keep the rear bins and seat base

Given the round tunnel and choice of rod gearbox I've elected to go with an internal gear linkage & make up our own bracket for the KAD linkage kit.

This looks great, amazing transformation in such a short space of time! Looking forward to hopefully seeing it in the flesh and picking your brain about good body shops and fabricators.

Really love the way this build is looking so far. Mk3's look awesome when built with an 'appendix k' ethos, just very few people do!

 

I'm not sure you'll have the legs to do a 'ring lap though. My old 1380cc with a 300 scatter cam used to pull about 7750 in top on a 3.9FD and I don't think that was even 110mph!

Thanks man, I guessed as much. I do have the option to change the FD by swapping out the primary gear from 24 tooth to either a 23 or 25 tooth to alter the ratio's either way. Do you think it would make enough of difference?

If you use 0.958 dops which IIRC is 24 tooth primary, 30 tooth idler & 23 tooth input. This should give you another 5ish mph @7750rpm in top. That's the tallest drop gear setup you can go with a 3.9FD.

 

For reference, to pull 115mph you will need about 105bhp @wheels @7750. That's calculated for a mini with no arches & 10" wheels. 

 

The max an appendix K mini will pull, not slip streaming, is about 120 ish at around 8200rpm. They use a 3.9 FD and have about 130bhp at the engine.

While we wait for the body to be painted I've shifted my focus to all the other jobs that need doing! I've been going through everything that came off the original car and worked out what we could keep, what needs refurb and what needs to be replaced.

 

Top of that list was the wheels as I plan to convert the car from drums to disc brakes in the front. Long term I want to have a set 'road' rims with a road going tyre and a set of 'race' rims with a track tyre. The idea being that the road wheels can be used for loading, MOT and any other time I need to be road legal. Therefore I order a set of C-21A1901A 5x10 Minilites which should help increase the track width a little.

 

I heard mixed reviews about the R7 tyre but in the end decided to try them as they have that period correct tread pattern we're going for. I want to keep the car as stock looking as possible on the outside. What do you think?

Personally I quite like R7s. I’m currently running aquajets on my mk1 and I’ve recently bought the new 145/10 blockleys for a set of reverse rims. Still went with good old A008s on my mk3 (also bronze yellow) though. Cheaper and work well.
