I'll repeat again, all the box is doing is upping rail pressure, the same end result as pushing the throttle down. And again, 30 mph in 4th is ~1450 RPM, at which point the standard 90 map is requesting 180 Nm of torque at WOT and getting ~15 MPG. You're suggesting that by increasing power further you're saving fuel? If your car is bogging down with a requested 180 Nm you have a more serious problem. Peak torque occurs after 2000 RPM, so dyno results are largely irrelevant for this. You seem to be getting very worked up over this!Northern_Mike wrote:The engine does not have enough power or torque without the box to potter along at 30 in 4th. With the box, it does.
How hard is that for you to understand? There's guys on the Berlingoforum who've dynoed the same box - without the box, 89BHP, 155lb/ft. With box, 107bhp, 186lb/ft.
Is that really so difficult?
You also haven't told me your theory on how putting an unknown additional quantity of fuel into the engine increases efficiency. I'm sure the guys in Citroen would be fairly curious too, you might even be able to make a few million with that idea!
