  1. Sorry Alistair, I don't have a curve yet. but should have in the next month. Please note mine will be a race engine with turbo
  2. I will run https://csi-ignition.com/ on my turbo racecar. Already tested on a 2liter NA engine of another customer and seems to run fine. I guess 123 and CSI are very comparable
  3. Hi Bauke, whereabout will you organise it? (Suitable location for a racecar?)
  4. Dear All, After 8 years of good fun and challenges with the 1998 Lotus Esprit GT3 it is time for something new. So therefore it's up for sale. To give the forum members a chance UI will list it here first exclusively for a while before it will be listed elswere. The has has 79k kilometers on the odometer. Engine is tweaked to ~320 hp (Attached the graph) Summary of the upgrades, Quaife LSD EFi Euro 4 ECU (Incl USB module) Deatchwerks injectors Borgwarner EFR 6258 Motorsport engine loom (Zomer Motorsport) Alunax tubular manifold Engine rebuild at 70k km with light weight conrods Upgraded clutch Calibration at DPengineering Boven-Leeuwen (Now calibrated on throttle position, runs very well, good cold start and no pops and bangs) Brake upgrade (PNM) Custom stainless motorsport exhaust Aluminium fuel tanks Extra set AWI monoblock wheels with V8 body panels (Not mounted) I will post some more details and pictures later
  5. The final Dyno result I'm very happy with. Now calibration on trottle position the car runs much smoother. Calibration improved on full load and part load points. No more pops and bangs, also cold start no problem.
  6. Looking for a set of Esprit S2 Speedline or S1 Wolfrace wheels.
  7. If you are not running the operating point close to the surge line at any point i the compressor map it will not bring much benefit. Pre-swirl only shifts the compressor map. For efficiency the pre-swirl vanes are only another drag increasing component within the air system. As both the I4 and V8 Esprit engines don't take a extreme amount of boost a situation that a compressor is benefitting from this pre-swirl system is very rare. Beter is it to select the best compressor and turbine combination to improve performance. Also a straight inlet before the compressor inlet important and overall as less restriction in the inlet as possible. (With a downside of increased intake noise)
