      That's an easy solution. The nipples will probably be welded on anyway. So turn the flange side of the nipples tube in a lathe to match the I'd of the untapped boss. Direct fit: weld them in. ...

      So I'm curious, any reason why you went with a 8.5 cage on a tube chassis instead of just jumping straight to 25.x? And any plans to try and correct "rear end" geometry to prevent squatting on...

      Density is mass/volume while pressure is force/area. You can convert pressure to density by factoring in temperature and volume. Comparing density directly to pressure is like comparing torque...

      That's correct. Higher compressor rpm to compensate for changes in absolute pressure. Why the ECU is set up that way, I do not know. I would expect that to be completely covered under absolute...
