TeemuM Posted January 25, 2016 Author Share Posted January 25, 2016 Awesome! Watch out once the boost bug bites you'll always want a little more. Lets hope that won´t happen. First plywood mockup of that SC bracket. Feel free to comment if you find some faults with this. This is my first supercharger build so all help would be appreciated.

TeemuM Posted January 27, 2016 Author Share Posted January 27, 2016 (edited) Well that didn´t work...There is no room for boost pipes. Only way compressor can be rotated is when boost pipe is directly up, and then it hits to hood. I think I need to relocate alternator so I can mount that charger lower.

TeemuM Posted February 3, 2016 Author Share Posted February 3, 2016 Here is final design of these brackets. These are going to be laser cutted from 10mm steel. Also ordered larger pulley to lower boost litte bit. However there seems to be some problems. That new pulley hits to that flange that is in front face of charger. In rotrex techinal drawing that flange height is 5mm and I have 8mm. So maybe this charger is older design, etc. However I think I need to machine 3mm off that flange to get enogh clearance.

TeemuM Posted February 15, 2016 Author Share Posted February 15, 2016 Now that engine work is done I had time to modify fuel tank. I wanted to use in-tank fuel pump, so needed to cut hole and weld that plate in place. Also made that bracket for Walbro 450 E85 fuel pump. That fuel pump bracket is going to be zink plated and inside of tank is going to be covered with Por15 fuel tank sealer. Quote Link to comment Share on other sites More sharing options...
TeemuM Posted March 19, 2016 Author Share Posted March 19, 2016 Fuel tank is now ready to be assembled. I did Por15 tank sealer treatment inside so hopefully it wont rust anymore. Pump is Walbro 450 E85 and I am using AEM high flow fuel filter. Quote Link to comment Share on other sites More sharing options...

TeemuM Posted April 16, 2016 Author Share Posted April 16, 2016 I drove about 200km with NA engine and then it was time for oil change and installing supercharger. Still lots of small thing to be done but at least it is now drivable. Small video of first start with Rotrex. http://teemum.kuvat.fi/kuvat/Datsun+240Z/Tekniikka/Moottori/2015-2016/sc_kaynnistys.mp4 Quote Link to comment Share on other sites More sharing options...

1969honda Posted April 16, 2016 Share Posted April 16, 2016 That's sweet, motor really torques to one side under load, gotta be a blast to run around in. Quote Link to comment Share on other sites More sharing options...
TeemuM Posted April 17, 2016 Author Share Posted April 17, 2016 Thanks! I quess my calculations were off because this only boosts about 0.5bar. I calculated that with this pulley boost pressure would be about 1 bar. Because pressure is so moderate there is not so big difference compared to NA engine. Well I can always change smaller pulley... Quote Link to comment Share on other sites More sharing options...
TeemuM Posted April 28, 2016 Author Share Posted April 28, 2016 (edited) Went to dyno yesterday. There was 360hp/420nm and that was only with 0.4bar. I am quite happy with results as boost pressure was so low. So there is much improvement available with smaller charger pulley. Also that 2.5" exhaust is too small so I need to do it again.

TeemuM Posted May 23, 2016 Author Share Posted May 23, 2016 I made small modification to exhaust pipe. Previously I had chambered single outlet muffler and I changed it to twin tip straight-through muffler. Like looks and sound with this one!

TeemuM Posted October 26, 2016 Author Share Posted October 26, 2016 (edited) I ended driving season this week. Drove little bit over 5000km in this summer and not a single problem. Attended few drag racing events and best time was 12.99@178kmh. Those were at airfield so traction was not so good. For next summer there is not going to be much changes. Little bit more boost, better intercooler and larger exhaust. For outside I bought original mirror to replace that plastic one and Euro-style front spoiler. Few driving videos. http://teemum.kuvat.fi/kuvat/Datsun+240Z/Sekalaista/kiihdytys.mp4 http://teemum.kuvat.fi/kuvat/Datsun+240Z/Sekalaista/Elokuva.mp4 Edited October 26, 2016 by TeemuM Quote Link to comment Share on other sites More sharing options...
TeemuM Posted December 19, 2016 Author Share Posted December 19, 2016 I got this aluminium radiator to replace original. I also put Spal electric fan so original fan shroud would not fit. I modeled new shroud, machined mold and used carbon fiber to made new one. Still needs few layers of clear coat and it´s ready! Quote Link to comment Share on other sites More sharing options...

TeemuM Posted December 31, 2016 Author Share Posted December 31, 2016 I fabricated new exhaust that replaces current 2.5". Its now 3" with two Dynamax mufflers. Also mounted larger intercooler and oil cooler for Rotrex. IC is treadstone and oil cooler is Setrab. Quote Link to comment Share on other sites More sharing options...
TeemuM Posted February 18, 2017 Author Share Posted February 18, 2017 Finally found time to finish fan shroud so radiator is ready to be installed. I cured that part in sauna. It made quite a bit difference to part stiffness. After that is was clear coated. I modified Nismo-style front spoiler. Now it fits quite well and atleast in my opinion it looks better. Now I need to make mold from it and manufacture new part. Quote Link to comment Share on other sites More sharing options...
