  1. Tin box, noisy when it rains, condensation, in hot weather it’s like a sauna, they always rust and hammerite paint is so much more expensive than wood stain or wood paint and then there is lightning…

  2. I have done a huge amount with the car over the last year and am now going to look at the geometry in a bit more detail, currently I have camber wedges on the back and little else, I have looked at the Haynes build your own sports car by Chris Gibbs, some very old notes from Track Developments and came across Caterham CSR settings and this is the confusion I am trying to deal with.

    across the 3 the range  for camber front is 0.25-1.5 degrees

    rear 0.66-2 degrees

    caster 5.5-6 degrees (CSR only)

    Toe front 0-0.5

    rear 0.16-3

    i am tempted to start with the Haynes settings but for now what are other peoples RH S3 settings for Caster, Camber & Toe Front and Rear


  3. I have been meaning to do this for some time on my S3, the problem is that I have Cobra seats with the seatbelts going over a crossbar on the roll bar and through the seats but mounting on the rear of the car meaning I need 2 pockets for the seats and some strategically placed cutouts and zips or Velcro, clearly this is way beyond my skills.

    where do I go? Who can help?

    Hi ian 

    have you a picture of it please would you know size where it connects yo 4-1 , cant be as loud as the cherry bomb ! 
    cheers Darren 

    Oh yes it is, my original RH can (I won’t call it a silencer as it was more of an amplifier) was way to load for SVA which had a 101db limit, I ended up having a silencer made, 1” wider and twice as long, re-packable and so much more liveable 

  5. Whilst ignition timing can cause sluggish starting my issue was engine earth strap, as always I over engineered the solution but it worked.

    I found that there wasn’t a strap from gearbox mounting bolt to chassis so fitted one.

    The earth strap from battery to engine was too thin, earth straps should be the same thickness as the +VE strap so I fitted the right thickness from battery to engine bay floor near the starter, from there I ran 1 earth to the bell housing bolt engine side and another direct to starter motor attachment bolt and this did the trick, starter ran faster and even starts my high compression 2.1 Pinto with wild cam and very advanced idle ignition

  6. I made my own one up but it seems that option is no longer valid. I got hold of a blank Robin Hood VIN plate, stamped it and riveted it to the engine bulkhead. I stamped the chassis in several places that are hidden under trim or in hard to get at places so if the car was stolen it would still be possible to identify it even if the obvious VIN stamping were cut out.

  7. Bob my FR32 cammed engine produces max bhp @ 5600 to 5700 rpm max torque is 4200

    my RL31 cammed engine was 173 bhp @ 6600 and 153 ft/lbs @ 4800 so I would expect the FR33 to sit around the middle of my 2 cams.

    would have to set the rev limiter to 7k but that said my FR32 engine runs injection rods and standard injection head and see’s 7500 on occasions the RL31 is built for near 8k but rev limit will be at 7500

  8. £370 sounds reasonable you’ll want main and big end bearings, injection rods are better than no-injection rods, you’ll be limited to 7k rpm which means your camshaft choice should reflect this.

    on my engines the FR32 was a good street cam but I felt I needed a bit more, the RL31 cam is the most extreme I have tried and the one featured in the Penguin motors videos 

  9. Just add that Graham started off by putting his Weber’s and modified distributor on my engine to get a base tune he was confident with, a standard distributor won’t cut it if you want to get the most out of your combination of bits.

  10. I am your man for info…

    I have built 2 x 2.1 Pinto’s one with +2.25 Pinto pistons and one with 93mm V6 pistons machined for circlips using Cosworth rods.

    you may know that I have spent months on Penguin motors dyno and my engine is in 5 of his YouTube videos and was in 3 Classic Ford magazine articles.

    First, if I was doing it again I wouldn’t  got straight to 2.1, it’s only a 5% increase in capacity.

    I would consider forged pistons as you can stop worrying about breaking a cast piston. 

    you need to work out what you want from the engine in so much as the cams that give you high power will push the peak torque and power way up the rev range and let’s be honest, it’s a road car.

    Even though I had an ex-race head it wasn’t as good as it could have been, not many people can build a good head.

    I based my 2.1 build on a very old Classic Ford article where they went full 2.1 with Vulcan engineering finishing it off, it made 166bhp, I made 175bhp but the Vulcan heads are still very good it’s just that Classic Ford didn’t make the best of it.

    Cosworth rods are longer (and forged) so the V6 pistons being shorter make the total length the same as a standard rod and piston.

    36mm 38mm chokes 


    Distributor Vs mapped 


    Weber Vs Bike carbs


    2.1 Bike carb test 


    what I would say is that the videos do t paint the full picture and after much fiddling with bike carbs and Megajolt they worked well with the Robin Hood 4-1 manifold and only dropped a few bhp and torques over the Weber’s, that said a 4-2-1 was better.

    I am happy to engage in more detail


  11. The recommissioning of my S3 is stumbling forward at a staggeringly slow pace but I’m starting to look at geometry.

    tie bars, Gaz coil overs. 180lbs rear 120lbs front and camber wedges.

    what are the settings for toe, camber and caster front and rear?

    I want to get it in the ballpark before tweaking it on the road, currently it’s a bit lively at the rear but planted at the front.
