andybp Posted February 7, 2018 Author Share Posted February 7, 2018 also the term " computational step to far for your setup " doesn't really apply as I mostly program directly in Gcode so no fancy cad/cam setup Quote Link to comment Share on other sites More sharing options...
Toon Chris Posted February 7, 2018 Share Posted February 7, 2018 Yes, I suppose it does bent the mind a bit with the calculation and one step wrong an a large, expensive block is a doorstop. If you are using an insulating spacer anyway I guess it would seem silly to waste the opportunity Quote Link to comment Share on other sites More sharing options...

andybp Posted February 7, 2018 Author Share Posted February 7, 2018 New thicker 10mm Phenolic spacer has arrived and I've cut a couple already the new one allows for a much smoother transition in the port shape compared to the 6mm material as can be seen in the pic below 1 Quote Link to comment Share on other sites More sharing options...
Keyser Posted February 8, 2018 Share Posted February 8, 2018 It's all over bar the shouting then! Just whack them on hook up the linkage and slap a controller on - Test fire on Sunday? Impressed as always mate 1 Quote Link to comment Share on other sites More sharing options...
andybp Posted February 13, 2018 Author Share Posted February 13, 2018 All of the 10mm phenolic spacers are cut and the thing I haven't mentioned so far, which is how I plan on bolting my manifold to the inlet manifold is sorted successfully the problem was that the mounting bolts for the throttle bodies and the manifold both wanted to occupy the same space so my solution is to cut a shaped pocket into the manifold below the throttle body mounts just big enough to get the nut on the mounting stud and get a ring spanner over the top I've still got the three pockets to cut on the other side and I still need to smoothe the ports so I guess I'll keep putting one foot in front of the other for a while yet 4 Quote Link to comment Share on other sites More sharing options...
andybp Posted February 17, 2018 Author Share Posted February 17, 2018 Thought I'd try to get some work done today I recently bought a new belt finger sander / power file whatever you want to call it also a bucket load of belts for it and 6 flap wheels so far I've got through 25 belts and all 6 flap wheels wish I'd bought softer ally for this manifold never mind I think I'm nearly there another hour and 10 more belts should see it done Quote Link to comment Share on other sites More sharing options...

Keyser Posted February 18, 2018 Share Posted February 18, 2018 Still upset as I have no phenolic spacers and you now have 10!!!!! I have one of those finger belt sanders I recently purchased and my impressions so far are - it's pants as soon as you apply any meaningful pressure the belt comes off - it may be me but not found it to be much good so far, I go through sanding disks, flap wheels and all other sorts of sanding paper at an alarming rate, I but it in bulk these days Keep up the good work mate its coming along and those little cut-outs will either be a great success or they will become "those f'ing cut-outs" I hope its the first one for your sake I spent the weekend repairing an oil line on a certain V8 engined 350z and then repairing a broken plug on my trailer winch so no fun tinkering and making things 1 Quote Link to comment Share on other sites More sharing options...
andybp Posted February 18, 2018 Author Share Posted February 18, 2018 No phenolic spacers how can you live with the shame just to tease you some more here they are all bolted down clearances aren't too bad either I've now removed my throttle bodies and fitted the original plenum as it's easier to take on and off so I can still use my Z and yes I know I need to change the date and time on my camera and take the plastic off the lense 3 Quote Link to comment Share on other sites More sharing options...
andybp Posted February 25, 2018 Author Share Posted February 25, 2018 The ports are all smoothed and finished now and I've started machining the arms for the throttle linkage hope to get some more done this week but it's supposed to snow and I'm on standby 3 Quote Link to comment Share on other sites More sharing options...
Keyser Posted February 26, 2018 Share Posted February 26, 2018 Looking good I don't get why snow will slow you down? But I don't know what you are "on standby" for - I think you just don't want to go outside if its a bit cold PS date on camera still needs sorting 1 Quote Link to comment Share on other sites More sharing options...
Toon Chris Posted February 26, 2018 Share Posted February 26, 2018 Nice and smooth Are you doing any aesthetic work on the block too? i.e. remove the toblerone effect? Or is it all about the mechanicals for you? 1 Quote Link to comment Share on other sites More sharing options...

andybp Posted March 4, 2018 Author Share Posted March 4, 2018 I've made the new arms for the individual banks and one for the servo I decided to use the modified throttle servo from my old ITB setup for now also made a mounting plate to mount the servo to the manifold then I machined a recess into the end of the manifold for it to fit into still plenty to do but it's getting there 3 Quote Link to comment Share on other sites More sharing options...

Toon Chris Posted March 9, 2018 Share Posted March 9, 2018 I like that layout as the angles mean get you more finesse over the smaller throttle opening where you want it for pootling about 1 Quote Link to comment Share on other sites More sharing options...

andybp Posted April 1, 2018 Author Share Posted April 1, 2018 Been a bit quiet for a while been busy with other stuff I needed to build a new controller for my CNC Mill and rebuild my cnc router so much to do and so little time Never mind back on track now The linkages are all pretty much sorted BMW used steel rod to connect the linkages together I chose to use ally in an attempt to reduce the overall mass the throttle servo would have to move the only problem with with this is that it flexes too much so I had to make a tie bar up using two M12 rose joints fixed in place with circlips the one in the picture is temporary just to prove it solves the problem which it does I've also fitted lighter springs to the throttle bodies also to reduce the load on the servo and the original injector ports have been tapped to accept 6mm push fit fittings for the vacuum takeoff . There's not too much left to do, print the velocity stacks but I won't do that until it's in and I can check clearances also I need to strip and clean everything before installation so really more than anything I need some time off work to get it finished 4 Quote Link to comment Share on other sites More sharing options...
andybp Posted April 13, 2018 Author Share Posted April 13, 2018 So I went to fit these this afternoon and found a problem. the arms that open the throttle bodies have to move up toward the bonnet to open and I need another inch of clearance the only way to get that is to cut the bonnet and that's not happening so unless some major inspiration comes to me in my sleep this project will end here. The missus offered to buy me a set of jenvey or obx ones but that wasn't really the point the only problem now is I have become a bit addicted to the noise Not sure what to do now so I'll sleep on it Quote Link to comment Share on other sites More sharing options...
Guest Posted April 13, 2018 Share Posted April 13, 2018 Would a bonnet with strategically placed vents not give them room to move or is that something you wish to avoid? What a major pain in the ass =( You should take your lovely lady up on the offer of a set of Jenvey ITBs if you can't engineer a solution!

Daisyduke Posted April 13, 2018 Share Posted April 13, 2018 Does a nismo bonnet have more clearance? Quote Link to comment Share on other sites More sharing options...
