Dracostan Posted July 14, 2017 Share Posted July 14, 2017 The only way to get finer adjustment on the linkages is to use double ended left/right threaded rods and matching rose joints & locking nuts. Or you could put a slight bend in the linkages and use a vice grip to flatten it to the 'right' amount Draco 1 Quote Link to comment Share on other sites More sharing options...

andybp Posted July 14, 2017 Author Share Posted July 14, 2017 As per the previous post I'm waiting for stuff to arrive so I can get on (AGAIN) so I thought I'd look at the strut brace, I was hoping that I could modify the brace a little to fit but there just isn't the clearance above so it's going to have to be more major than I had hoped (luckily I know where there's some stainless looking for a new home 1 Quote Link to comment Share on other sites More sharing options...
andybp Posted July 17, 2017 Author Share Posted July 17, 2017 The new linkages are all sorted now so the throttle bodies are all balanced now and it's made a massive improvement to the idle also I've been stuck in front of my computer for the last hour redesigning some new velocity stacks as I had a few clearance issues with the front ones just touching the bonnet will get one of these printed tomorrow hopefully also my new wideband controller arrived so I can get an O2 sensor in the other downpipe 2 Quote Link to comment Share on other sites More sharing options...
andybp Posted July 23, 2017 Author Share Posted July 23, 2017 sorry for my lack of updates but it's all been a bit slow I couldn't get the new velocity stacks made due to a problem with my 3d printer (awaiting spares) . I have managed to get my other wideband o2 sensor in so now have one in each manifold which will help me with the tuning, which is getting there slowly but surely it gets more driveable and smooth every day The strut brace is on hold until I get my gas refilled (tomorrow hopefully) but the big news is that I might have to rename my Z from Christine (after she tried to kill me) to Snarling beast as the sound the exhaust now makes is so f****** awesome 3 Quote Link to comment Share on other sites More sharing options...

andybp Posted July 30, 2017 Author Share Posted July 30, 2017 have started on the strut brace took ages to get the bends right Now that bits in the rest should go a lot quicker also I've put fine mesh stainless filters over the velocity stacks and coated the stacks with resin to make them more heat resistant I've not been too fussy with this as I'll be changing the velocity stacks due to clearance issues that is once my new 3d printer arrives as I had a major meltdown with my old one and it's not worth repairing I've also been tuning the car on the road with the help of my wideband sensors the fuel map's getting better all of the time once I get it a bit better and some of the bugs sorted out I'll take it and get it mapped hopefully by the end of next month. 4 Quote Link to comment Share on other sites More sharing options...

Can't wait to see (hear) the car passing by. the cars running fine sounds great lot of work still needs doing though one of the velocity stacks is just hitting the bonnet so i'm making new ones now that I've built my new 3d printer VID_20170809_201656.mp4 also had some problems with one of my wideband sensors so I've got to fit a new one which arrived today once I get the new velocity stacks printed and the new sensor in I can get on with tuning I also need to finish the strut brace and finish the crankcase ventilation setup 1 Quote Link to comment Share on other sites More sharing options...

You should of looked at the Link CAN Lambda set up. Far more accurate and more reliable output than a normal 0-5v output lambda/AFR. Quote Link to comment Share on other sites More sharing options...

It's a modified 350z throttle body with a lighter return spring also the outer throttle bodies have had the return springs removed I did consider the link can lambda setup but I already had a new wideband lsu 4.9 sensor and controller so it was easier and £200+ cheaper to buy another of these and since this car is only a toy and a test bed for my Mad ideas as Keyser calls them I like to keep what I spend under control 1 Quote Link to comment Share on other sites More sharing options...
andybp Posted August 14, 2017 Author Share Posted August 14, 2017 The wideband sensor issue I had is now sorted I now have the same sensors and controllers in both banks and I have designed and made new velocity stacks which are angled to avoid the bonnet and have a flat side to allow for fitting of proper filters consisting of shaped aluminium mesh and RAM AIR dual layer filter foam. 4 Quote Link to comment Share on other sites More sharing options...

andybp Posted August 18, 2017 Author Share Posted August 18, 2017 so the latest update is pretty minor but has made a huge difference if you look in the picture below you can probably make out the maf sensor cable tied to the loom next to the 2 rear air filters this was still connected because the maf sensor also contains the air inlet temperature sensor which is required for correct fueling but being where it is this was measuring engine bay temperature so I have now drilled a small hole in one of the velocity stacks and mounted a bead thermistor into it and spliced it into the loom so I'm now measuring the correct temperature and the MAF is no longer connected. so what's left to do ? top of the list is to get a decent audio/video clip posted before I get lynched. finish the strut brace. do something with the crankcase ventilation (not just a pipe hanging in the wheel arch). get it tuned properly on a rolling road. this project hasn't taken too long really and if I'd given up on the utec ecu sooner I could probably of shaved a month off but never mind it's nearly done. I've already decided my next project after I've tidied up my interior will probably be air ride suspension and no don't be silly of course I won't be buying it off the shelf 2 Quote Link to comment Share on other sites More sharing options...
Jay84 Posted August 19, 2017 Share Posted August 19, 2017 That looks truly awesome well done. Would performance be hampered by pulling in hot air from the engine bay? It's not a criticism, more an understanding thing for my lack of knowledge. 1 Quote Link to comment Share on other sites More sharing options...
