  1. Short update on delivery for the 1st production run customers: 5 pairs for JAE in machining 4 pairs for remaining customers will be roughed by end of December and completed for delivery/collection by end of January 2023.
  2. This is an example of the clearance required for the V8, but it would not be hugely different for the 4-cylinder
  3. No. Nothing different that would necessitate that. Puling the transmission to change the clutch is a straight-forward task that takes only a few hours.
  4. Genuine new replacements are pretty much unnobtainium at this point. If yours are still serviceable, then you can have them rebuilt to include a 360deg bearing pad and staggered gap oil seals. This would be by far your cheapest route.

  5. I used a pair of decent sizes barrel chargecoolers on one of my previous V8 projects (the ex-5th Gear V8-GT). The engine made of 510bhp with just over 1.1 bar boost. It is not possible to use these coolers and retain the full boot area - there is just not sufficient space. It might be possible to use smaller barrels and place them stacked horizontally in the very front of the boot area. In my opinion, these barrel type coolers are not the most efficient due to their construction, but they certainly did work.
  6. Hi, Are you looking for a stock rear upright? I do have my old old pair of cast ones available. Mike
  7. I don`t think that ProAlloy will provide the CAD data, but perhaps @cweeden is making some "behind the scenes" progress with them? You can use the same coolant as used for your engine, it is just held in a separate fluid circuit.
  8. The first customer pair of rear uprights arrived this morning and I have fitted the one side. Everything fits perfectly and the end product is fabulous in my opinion.
  9. Pedal box bolts - specifically the left hand front bolt......
  10. The rear uprights have arrived and will be installed over the weekend. Side-by-side comparison is interesting
  11. My 500+bhp Esprit project car is for sale, with all of the work already done. Feel free to PM me if you are interested.
  12. Small update: production of the remaining parts of this first batch are continuing. Once the machining of the full run is completed, they will be sent collectively for anodising. Projection is that the parts will be ready for collection/shipping in December.
  13. Looks like Christmas is coming early this year 😀 Here are my CNC rear uprights prepared by Aira Technology in the UK. As a special favour to me, Alex arranged for black anodising to match the chassis. Can`t wait to get these fitted.
  14. Excellent. A lovely Winter project that will be ready for 2023.
  15. You can read up about typical intercooler efficiency, but typically air-to-air is considered less efficient than water-to-air. A decent well sized water-to-air system can result in 85-90% efficiency. This means that if your turbo has compressed the air to a temperature of 70degC, then your intercooler can lower that by 85-90%. Important to understand is that your intercooler obviously cannot lower the temperature below ambient. Drag cars can manage that by adding something colder into the equasion (e.g Ice or another gas), but for road you are safe with that constraint. In practical terms for you living in a hot climate - with decen intecooling, you would expect your inlet temparature to be within 20degC of ambient. Power-wise, I don`t have actual figures but would imagine that in hot conditions where the inlet temperatures of a non-intercooled engine are constraintly high, power could be down by 10% or more.
  16. What is currently fitted to the car? If you have 200cpi sport cats fitted, then these will not pass CA smog checks. It could be that you just need 400cpi cats which are widely available.
  17. The IAT sensor position would need to be changed to consider the inlet temperature after the intercooler. If the IAT sensor is positioned before the intercooling, then the ECU would based the fuelling enrichment and ignition timing on the hot inlet temperature.
  18. You cannot remove the fork fully from the bellhousing in situ. There is a slot in the fork so it can be moved up to disengage the release bearing for gearbox removal. By removing he slave, you should be able to see the fork is engaged on the release bearing. Pull it up fully to disengage and then back down to ensure it is seating correctly. You will see that it can only be seated fully with the release bearing in the correct orientation. It does take some positive force to engage. When seated correctl, once the slave is fitted it should be impossible for the fork to disengage during normal operation. See the profile of the fork ends in the image below.
  19. @cweeden This is where I recommend you move to either CP Carrillo or even better, Saenz rods.
  20. @Barrykearley Yes. They have the ABS sensor positions for the V8 and also the VSS sensor position for the later 4-cylinder cars. The VSS position is absent on this first set as they are for me.
  21. Update on CNC rear uprights: The first customer pair are completed and heading off for anodising. On the topic of anodising, after examining the finished parts the guys at Aira have changed the anodising specification from 'Hard Anodising' to 'Sulphuric Anodising'. This decision was made as they deemed the trade-off in fatigue life of the uprights for the harder-wearing surface that comes with hard anodising is not necessary for this component. Switching to the sulpuric anodising reduces the impact on fatigue life, while providing a harder-wearing surface than the conventional chromic anodising, and still maintains anti-corrosion properties. Production of the remaining units is underway with roughing of the billets already started. The eagle-eyed will notice that this pair do not have the provision for the VSS sensor. All remaining pair do have that design feature incorporated. Enjoy the images of the finished parts and a big well done to Aira for their work turning this project into a reality. video-e74f1b26-cdbd-4bbb-957a-b7c4d9bb28fa-1664363586.mp4
