No I have not, but when I was listening for the source of the noise yesterday, it was definitely coming from the supercharger. When it's running a bit better, would love to hear an exhaust video as I bet it sounds amazing. Quote Link to comment Share on other sites More sharing options...

J-Meiser Posted September 13, 2021 Author Share Posted September 13, 2021 Hi everyone, Just a quick update this evening. Since my last update, I have taken the supercharger assembly apart, cleaned it all up and I am now reassembling it all. I noticed, during the disassembly, that 2 of the bolts that held the throttle body in place were very loose. I believe that, due to my enthusiasm to do the first start, I put them in place to hold the throttle body, but forgot to go back and tighten them up properly later on. I would be very surprised if that was not a major contributor to the issues that I experienced. Over the course of the weekend, I have mounted the supercharger again, having refitted and sealed the inlet manifold and top plate. I swapped out the IAT sensor for a new one and this time, it screwed in securely, so that should improve the seal in the manifold. The remainder of the new spring chips arrived, so the PCV lines have all been connected up properly. I have replaced the stock spring clips used on the IACV bypassed line with the new, stronger clips in the hope that this will provide a better seal. The next jobs on my "To-Do" list are to reinstall the fuel lines, refit the throttle body adapter and in turn, the throttle body, making sure that all bolts are properly tightened up. After that, it will be the inlet piping, radiator, radiator pipes and the battery. There's not much left, but I am not rushing it; not after what happened last time! I was really hoping to be able to go on DragonCol, but it is not looking likely. I have not taken any pictures as almost everything I am doing now, I have already done and photographed before, but should I do anything drastically different, I will take a picture and share . Thanks for reading and I hope to have another update soon! 4 Quote Link to comment Share on other sites More sharing options...
mattdavies Posted September 14, 2021 Share Posted September 14, 2021 Hopefully you have found the issue. What management will you be running this on ? Quote Link to comment Share on other sites More sharing options...
J-Meiser Posted September 14, 2021 Author Share Posted September 14, 2021 Hopefully so! I suppose the proof will be in the next time I try starting the engine . At the moment, I will be sticking with the stock ECU. All of the research that I carried out appears to support the fact that it can cope with the setup that I will be running, but again, we shall have to see. If the ECU does have a hissy fit, I will look into an aftermarket one. I will have to find one that supports cruise control and an automatic transmission. I'm not sure how many of there actually do that, so it could get interesting . Quote Link to comment Share on other sites More sharing options...

J-Meiser Posted September 17, 2021 Author Share Posted September 17, 2021 Morning everyone! Another small update. Since my last update I have been able to work through almost everything on my "To-Do" list, so yesterday evening I drafted in my wife for another attempt at getting this started. This is how it went: There is still a small leak somewhere, as it did screech a bit, but nowhere near a badly as before. Also, when the engine was turned off and everything was still, I could hear the sound of air escaping, so I will track that down and fingers crossed, that should be it for this phase! The next phase will be sorting out the water/methanol system. 3 Quote Link to comment Share on other sites More sharing options...

J-Meiser Posted September 28, 2021 Author Share Posted September 28, 2021 Hi all, Since my last update I have been chasing down the leak and it has been a real nuisance to find. I had to take a break from hunting it in the end and do a couple of other jobs that I had been on my to-do list for a while. I started off by changing the fuel pumps. I had a Walbro GSS341 fuel pump waiting in my “parts store” for ages, so as I could safely rule out the fuel pump as an issue, I figured that I may as well swap them over. It came already fitted on the hanger, fully wired up, so swapping them over was a straightforward job. I conducted a start-up test and the engine fired up first time! I was impressed, considering that it had been sitting in a box on a shelf in my garage for over 2 years! I wanted to be certain that the bonnet would close properly and that the supercharger had sufficient clearance when it was closed. I would have been incredibly annoyed if, after all this work, the supercharger pulley caught on the bonnet, despite all the checks and measurements that I conducted earlier on in the build. I cut a small square out of the bonnet liner, closed the bonnet and, thankfully, it closed without issue. I repeated the test, with the engine running and again, no interference issues with the bonnet closed. Success! I needed to turn my Supra around for a bit, so as a final check, I drove it down the driveway, turned it around on the road and then brought it back up the drive. I made sure that it was not slow, just so that there would be some movement in the bay – it is all good so far. I just hope that it remains that way when I do get back out on the roads. Once I had finished all my other jobs, I set about finding the leak(s) once more. Having checked all the pipes connecting to the supercharger, I was able to rule them out. However, listening to the leak, it sounded as though it was coming from the throttle body side of the supercharger, so I decided to dismantle the inlet tract up to the supercharger, check the connections and go from there. I found that the pipe that connected to the IACV had a bit of a gap where it connected to the IACV, so I cleaned up the hard pipe and applied some sealant to try and improve the seal. I checked the mating faces of the throttle body adapter after noticing that there was black “soot” at the bottom of the throttle body gasket, which indicated that the mating faces were not quite making an air-tight seal with the gasket. The adapter-to-supercharger face was perfect. However, the adapter-to-throttle body face was a little uneven in places, so I carefully ground down the uneven areas until they were comparable to the straight edge that I was using for reference. Once I was happy that I had done everything in my power to get the best seal possible, I reassembled the inlet tract, making sure that all the bolts were properly torqued and then conducted a start-up test. Here is how it went: FINALLY ! With the engine now running smoothly, I am going to fill it with coolant, then finish plumbing in the water/methanol system and then sort out the wiring/electronic side of the system. Once that is complete, I will review my to-do list and try to tick off a few more jobs. The build continues! 6 Quote Link to comment Share on other sites More sharing options...
Annabella Posted September 28, 2021 Share Posted September 28, 2021 Awesome!!!! Sounded brilliant and not too much Supercharger whine! Just right. Looking forward to some onboard filmed cabin runs You might want to seal up around the cutout in the bonnet damper, dont want any fluff dropping in the SC pulley.

J-Meiser Posted September 29, 2021 Author Share Posted September 29, 2021 Thanks Annabella! I am yet to really open the throttle (I do not want to deafen the neighbours!) but the whine is quite subtle at the moment. Conditions (and petrol) permitting, I will try my best to get some cabin videos sorted as soon as I can. Yes, good point regarding the fluff; I will get that sorted out. Thank you!

TheTurtleshead Posted October 5, 2021 Share Posted October 5, 2021 Great stuff chap! Great level of perseverance shown there Your mating faces though, if you still experience problems with air leaks,some sand paper on a nice flat block is the best way to clean and level them out dead flat. 1 Quote Link to comment Share on other sites More sharing options...
J-Meiser Posted October 5, 2021 Author Share Posted October 5, 2021 Thank you very much! It has been far more work than I anticipated, but I am really glad that it is up and running smoothly now. Thanks for the flat block/sandpaper suggestion! I did not think of that. I will be keeping a close eye and ear on my engine as everything settles down, so if I get an inkling of a leak, I will give that a go. I already had spare gaskets on order, just in case .

J-Meiser Posted October 15, 2021 Author Share Posted October 15, 2021 Good evening all! I only have a small update this evening. I am still yet to take it out on the roads and see what it can do. On the two drives to and from the MOT station, I was pretty careful as I was listening out for any odd noises and also trying to see if anything felt wrong whilst driving. I am pleased to report that it felt and drove fine! Since then it has been sitting in my garage while I sort out some wiring . I have a few accessories to add and I wanted to wire them in properly, so I decided to utilise the blank spot in the fuse box where the EFI 2 relay should be and mimic the EFI 2 setup from the TT. Once that was in and the wire fed through to the cabin, I finalised the wiring for the controller for the water methanol system and switched on the ignition to test it out. It came online perfectly . The next steps are to some wires to the boot for the fluid level sensor and pump power, test, then fill up the system and test again before fitting nozzle to the intake and going out for a test drive! 3 Quote Link to comment Share on other sites More sharing options...
J-Meiser Posted October 18, 2021 Author Share Posted October 18, 2021 (edited) Hello everyone, I took my Supra out for a run today, as I finished installing the water-methanol system over the weekend. I need to fine tune the system a bit, as I do experience some bogging at lower RPMs but it does come alive at 4500-5000 RPM all the way to redline. Here's a very small snippet from my drive today. I still have more work to do, but it is getting there! Edited October 18, 2021 by J-Meiser (see edit history) 6 Quote Link to comment Share on other sites More sharing options...

Frank Bullitt Posted October 18, 2021 Share Posted October 18, 2021 A supercharger is such a compliment to the V8 and the sound is amazing. Much better than the turbo route, single or twin. Is the bypass valve working correctly? Quote Link to comment Share on other sites More sharing options...

How come you're able to just throw a charger on and WOT? You make it sound so simple and straightforward ! It has been a lot of work but it looks like all of my time and research is paying off. Add to that a lot of blood, sweat, tears and prayers (all of it, literally) and this is where it has got me to. I do agree, it does sound awesome. If I don't look happy in the video, it is because I am concentrating, making sure that everything is ok. That was one of my first few WOT pulls, so I was hoping that nothing broke! 16 hours ago, Frank Bullitt said: A supercharger is such a compliment to the V8 and the sound is amazing. Much better than the turbo route, single or twin. Is the bypass valve working correctly? While it was at the MOT station having the emissions test carried out, I was able to stand by the engine bay and I was watching the bypass valve as the engine was taken through the rev range. I them asked if they could rev it to the redline once they had finished, just so I could check and yes, it did close properly. On the drive today, I hit a max of 10 psi, but most of the WOT runs sat stable at 9 psi. When driving normally, I could see the boost coming online and going away consistently, depending on how much throttle I was using, so I am confident that it is working properly . Once I get the SupraStick operational again, I intend to try and take it to a dyno, as I would like to know what it putting down and whether there are any issues throughout the rev range.
