Colour is amazing and I dread to think how much $$ has gone to the engine build- it'll have so much character though, I'm sure it'll worth it:) Ignorant question, why would you reduce the alternator speed? It's not like that car will be sitting@8k rpm all the time, would the charge be sufficient in normal driving? Also, what I found with these cars is that the gear change is not perfect when on it and at the higher end of the rev range - the box just does not want to play ball, how would things be at an even higher rev limit? Have you made any improvements on that front or is it not a concern? Finally, where did you get the cupR engine cover please? Thanks and looking forward to videos! Reducing alternator speed helps reduce damage at high rpm and gives you more power/response as there is less drain on the engine. Doesn’t need to run at full speed as the car doesn’t have anywhere near the amount of electrical need as a Camry or Lexus. Will be totally fine to power everything even while idling. My gear shift has always felt great. The box has been completed rebuild with all new parts and cryo treated. Also brazed on metal tips for the shifter forks to replace the crappy plastic ones that snap. The gearbox is the biggest unknown in this project, as very few are running this kind of power and rpm. However it is a strong, well designed gearbox, so fingers crossed. If it fails, I’ll probably replace it with Jubu’s manual box or maybe go DSG. Cup R engine cover came from John Seal @ Lotus Hardtops. Intake manifold with big injectors and fuel rail now on Here you can see the additional oil drain we plumbed in 3 Quote Link to comment Share on other sites More sharing options...

Mattmahope Posted November 8, 2022 Author Report Share Posted November 8, 2022 Engine now back in the car and looking great! The powdercoated subframe also looks good and Sam painted the engine mounts to match. Everything else has been vapour blasted so all nice and shiny! 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Mattmahope Posted November 9, 2022 Author Popular Post Report Share Posted November 9, 2022 Current status at Back on Track. More progress but still a long way to go. Next step is the new engine wiring loom which will probably take three weeks or so. Thanks to @Gordon S for the picture. 3 2 Quote Link to comment Share on other sites More sharing options...

Mattmahope Posted November 10, 2022 Author Report Share Posted November 10, 2022 Pleased with how the retrimmed interior is looking. Especially happy with the new vents. They fit perfectly! 1 Quote Link to comment Share on other sites More sharing options...
Mattmahope Posted November 11, 2022 Author Report Share Posted November 11, 2022 You can see how massive the Harrop TVS1900 charger is here. It is also bloody heavy unfortunately. I’d be interested to know how much heavier it is than the Edelbrock standard chargecooled version. Any ideas? Decided to use this stuff as coolant for the engine and supercharger to keep temps down as much as possible: https://www.demon-tweeks.com/red-line-supercool-fortified-with-water-wetter-premix-red81215/ Wasn't cheap but hoped worth the investment as it should last 5 years. It’s amazing how much coolant is needed. You can see why there is such a big difference between wet and dry weights quotes by manufacturers. 1 Quote Link to comment Share on other sites More sharing options...
DangerousDave Posted November 14, 2022 Report Share Posted November 14, 2022 I remember synchros was the problem with highspeed lock out shifting hopefully it's just shift forks with this transmisison. Quote Link to comment Share on other sites More sharing options...
Mattmahope Posted November 21, 2022 Author Report Share Posted November 21, 2022 Exhaust going back on now. Love how you can see the gold engine bay lining reflected in the Zircotec coating. New braided line for the clutch with new adjustable delay valve. Hopefully it will allow us to fine tune the clutch feel to make the twin plate manageable on road. Good progress with preparation of the new engine loom 2 Quote Link to comment Share on other sites More sharing options...

Mattmahope Posted November 25, 2022 Author Report Share Posted November 25, 2022 Good progress with the wiring. From this… To this… So much cleaner and more weight saving. Also added a connector so that all the wiring to the rear of the car can be easily disconnected/re-connected for removal and reinstallation of the rear clam. 1 Quote Link to comment Share on other sites More sharing options...

I think they put a lot of the wiring down the sills but I’m really not sure to be honest. On 03/12/2022 at 23:55, MrD said: Fantastic stuff - who did your interior trimming pls? Something that I'm looking to get it done - cheers. Was all arranged via Back On Track. They have done a fantastic job at coordinating the whole project. A few more close up shots of the interior, including the control panel for the TracTive dampers mounted in the stereo slot along with USB slots for the driver and passenger. 1 Quote Link to comment Share on other sites More sharing options...
Mattmahope Posted February 5 Author Report Share Posted February 5 Brakes have been refurbished and look great. All the suspension parts have been replaced and/or powdercoated, and the inside of the wheel arches have been ceramic coated to make it easier to keep clean. 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Mattmahope Posted February 5 Author Popular Post Report Share Posted February 5 But here is what we have all been waiting for… the initial dyno test results… Main goal accomplished - it revs to over 8,000rpm and is super responsive. Listen to the blips at the end of the video! Second goal accomplished - super smooth power and torque curves from low down all the way to screaming at the top end. Third goal accomplished - relatively low boost of only around 0.6bar and nice low inlet and engine temps to aid longevity. It should be able to put out the power all day in hot conditions on track. Finally, and least importantly for me, some very healthy power/torque headline numbers - 551hp and 552NM. We could have got much more power by using a smaller pulley, cranking up boost and lowering the redline, but that was not the goal of my build. Also no point in gunning for massive numbers as the gearbox won’t cope on track. It’s already at the limit as it is! Very pleased with the results so far.
