...was trying to review some of my tune information after my El Mirage event... I've been having a small problem getting the bike to make the rated spring pressure boost levels (it's always 2-4 psi lower than it should be). When I thew in the "7psi" spring the reference line accidentally got separated from the compressor housing and I didn't catch the mistake. What you see below represents a 15-16psi pull, hazing the tire at 90mph up to ~4500rpm. @ 6800rpm it went dead rich on the safeties, misfiring and effectively ending the run. For the record, this made as much wheel torque in 4th gear than a highly tuned -1/+4 geared Suzuki B-King does in FIRST GEAR. I have a feeling she would make about 420-440ish at 9krpm if I sort the tune out. Ha ha, he he, ho ho.
Getting ready for the race this weekend, trying to play with the boost controller to get a good flat torque "curve" out to redline. Clean pull to 9k, intake pressure checking in at 169kpa (10psi) on that run at 8000rpm. Mixture is targeting a little over rich (around 11.1 at 10psi, 11.6 at 7psi), and she wants to lay down a bit after 8500.... but that was an easy 400 if I leaned it out a bit. Still need to optimize ignition timing too.
I'm going to back it up to about 3psi up to 7500rpm, then ramp it up to about 6-7 psi up to redline for the first pass... that's good for about 290ish to 360hp... and hopefully 195mph.
King were thinking that intercooler punches a hugh hole, is that the case? Those angles you have in it look precise for angled flow after fist punch to air youre hitting. On track or way off
