    Post Turbo Spool with a 56mm Hybrid

    As per the title, here is a graph generated using the OPCOM data log from my current turbo. I have reduced water/methanol quantity down to 0.4 ltr/min from my normal 0.8 because the over boost was too aggessive on the current map and I have requested a slight reduction in VNT around there. One I get my controller back I'll be able to modify the flow to reduce it there too but I have lent it out for a few weeks, leaving me with only pressure activation.

    This is fith gear as stated to keep under the speed limit Sixth would spool a little earlier, even more so with the full amount of water/methanol running.

    Going to plonk it on the rollers down in Fareham to see what it is doing now. I expect les bhp then the last run with a much bigger compressor but alot more torque than the poor 350lbft it reached over at above 3000rpm.

    Barametric pressure on the day was vertually bang on 100 but the readings on the graph are absolute, so 300 is about 2bar above atmospheric here (29psi).

    The bottom axis is just time
