BNR 2871 is not very stable above 27 psi and you would have had a more massive torque spike but a large fall up top. Hp would have been about the same but reached at a lower RPM and peak torque would been higher of course. Likely 3-4* less midrange spark can be run at 30 psi with the BNR especially on 93 octane. Forty's setup with the 5th injector on E-85 should make around 450-460 whp at 26-27 psi on the dyno dynamics load type dyno he uses. Made 368 whp and 446 wrtq at 24 psi max no huge boost spike with stock turbo on E-85 with the car right on the edge of injection window misfire (6.2-6.5 Ms injection times up at 6500-7200 RPMs even with ZZPs big fuel lobe cams, 2500 psi rail pressure holding throughout (tried higher but would not hold over 2500 psi no matter what I commanded) and a very advanced injection angle

Actually teams car is similiar to my setup but with a larger turbine wheel but my compressor wheel is larger.
And I'm not seeing 40rtys car hit 450-460 whp on the beaner turbo ... 430-440 on a close reading dyno..

Nope my turbo isn't a 20g its much larger.. Same with teams turbo. Much larger then the 2871.. Teams setup is based off my setup basically just more for his setup because he revs out..
