94RF1146 Posted December 30, 2021 Posted December 30, 2021 (edited) Hi guys, I know it's been a while... About 3/4 done with my build. awaiting pistons & rings then I'll start the harness. The build: - 94 RF frame (1/2) - 1290cc motor - 30/27 valves + HD spring set @ 85 lbs - Webcam .383 / .342 - Gen 1 Busa 46mm TB - Custom fuel rail / -8 fuel line - 400 l/hr fuel pump - 1700cc injectors - Garrett GTX3576R Gen 2 turbo on Ethanol - MaxxEcu Sport - 68-70" wheelbase - Custom sub-frame - Air to water intercooler running iced water - Gen 2 Busa 3/4 bodywork for rider position / aerodynamics ( my RF bodywork was cracked and the riding position didn't permit me to hide behind the screen) It's crazy the amount of fabrication on a turbo bike. i like the challenge / engineering part of it. Should be ready by spring. I got help from friends. Edited January 1, 2022 by 94RF1146 addition 6 Quote
94RF1146 Posted December 30, 2021 Author Posted December 30, 2021 Hi , Do you guys use Suzuki Idle Control Valve ? Cheers. Quote
Arttu Posted December 30, 2021 Posted December 30, 2021 Hi, Nice to see your project here too! Regarding the idle control valve, I haven't used them on any of my EFI projects by this far. In my opinion it's more like luxury than essential thing. Basically you need it only if you want to keep the idle rpm exactly stable without any manual intervention. Especially for a race bike this isn't a big deal, IMO. Quote
NorthernBloke Posted December 30, 2021 Posted December 30, 2021 Very interesting project, what - 1290cc motor are you using, Oil cooled, Water boiler or Busa? Quote

Not sure how long a valve would last in a potentially boosted environment? The smart money usually uses ignition timing for idle control - a quick raise in timing just before stall zone, ups engine speed to the normal control area. Quote

94RF1146 Posted December 30, 2021 Author Posted December 30, 2021 I'm also planning on building another plenum with less angles in it. 3 Quote
mikeyd Posted December 31, 2021 Posted December 31, 2021 Very interesting indeed! What's the third outlet for on the fuel rail? Quote
94RF1146 Posted December 31, 2021 Author Posted December 31, 2021 I'm feeding it from both ends and return from the middle. Quote

94RF1146 Posted January 1, 2022 Author Posted January 1, 2022 That's the plan. Turbo, fuel system and other components carefully selected... I'll share the dyno sheet after tuning and videos / timeslips going down the track next season. Don't underestimate those 1100 wc motors. MM 1 Quote
Pasis Posted January 1, 2022 Posted January 1, 2022 Hi, Martin! Your project is very interesting! I've been following him for many years! 1100w is not a bad engine, but with such power there will be constant problems with the stiffness of the cylinder block, so in my project I switched directly to the billet block. And also I think there will be problems with the transmission. Nitro - from Germany has made some serious progress with this engine 3 Quote
94RF1146 Posted January 3, 2022 Author Posted January 3, 2022 Here's the link from where I got my exhaust collector. https://www.turbozentrum.de/4-Cyl-CNC-stainless-steel-V-Band-collector-for-TiAL-GT28R-GT30R-GT35R-with-38mm-Wastegate-port Cheers, MM Quote
94RF1146 Posted January 8, 2022 Author Posted January 8, 2022 Crank & rods.. Case clearances... 1700 cc Injectors... 400 l/hr Fuel pump... Talked with APE yesterday about my pistons order, apparently JE lead time is 8 weeks and CP up to 16 weeks ! Cheers, MM 3 Quote
94RF1146 Posted March 4, 2022 Author Posted March 4, 2022 Hi , it's been a while.... I decided to simplify my setup and save some weight. I didn't like the look of the plenum and my subframe. got myself a Miller welding machine and having fun with it. Made a new plenum and started on the subframe. I want my bike running by the end of the month. 4 Quote
Arttu Posted March 4, 2022 Posted March 4, 2022 So are you going to run it without intercooling? Quote
Gixer1460 Posted March 4, 2022 Posted March 4, 2022 'Up and Overs' is the way to go - if you have the space! Personally, I would have stuffed the BOV next to the plenum so simplifying the up pipe - but that's just me LOL! Quote

94RF1146 Posted March 11, 2022 Author Posted March 11, 2022 Good progress today. Subframe almost done. Cooling system done. MM 3 Quote
