      Flipped M42/44 water pump pulley with special adapter to drive the alternator 1 to 1 with the crank.
      Stock is 1 to ~3+ overdrive !

    Hey man, how do you have the front of your cage set up?

      Hello, not sure what you are asking.
      Overhead bars from main roll hoop forward, then follow the A-pillar down, thru the dash, and to the floor. Both sides. Front cross to join the 2 at the top of the windshield, and thru the dash.
      Both doors are simple = 2 bars with 3 verticals, projecting into the doors.
      The cage is legal for most all racing bodies.

    Hey, this plenum is compatible whit stock ecu ? Saludos desde Argentina 🇦🇷

      you could run stock ecu but will need custom tuning. Need bigger fuel injectors to support ~200+ hp. The problem with e36 Bosch 282 and 990 box is that the full throttle fuel map is hard coded. Change the EPROM fuel numbers will not have any affect. The best is to use the e30 Bosch 175 box which allows you to tune the full throttle fuel map and as well as all of the other fuel and ignition maps. I ran 1 season with the 175 box.

      @@jaybee5390 I tried that... no effect on the AFR ratios. Tried all settings, on many different maps.
      The only way to make it work (crude) was to adjust the master injector size so the WOT was safe (but very rich in spots), and then tune the idle the part throttle maps.

      What is your ecu number? Whats the coding? 801E?

      990 box = WOT 1st cell = 5067h, 1x16 map
      282 box = WOT 1st cell = 51BAh, 1x16 map
      175 box = there are 4 1x16 WOT fuel maps, varies by regional coding. USA cars use the 4th map, 525Ah 1x16 map

      wow, this is an unlabeled table and with no axis references. I don't know if I'll be able to try this again.
      I've moved onto to a LINK standalone ECU and run with Speed-Density, or AlfaN setup.
