Torque curves

Does anybody know where i can get torque curves for the various engines? Preferably un-modified engines, and ideally also going down to fairly low revs.

Ja Peter dit gaan moeilik wees om so iets te kry. Dyno dag gaan die enigste way wees.
Ek het standaard TD42 curves, maar als begin eers op 1,500rpm.
Vir een of ander rede dyno almal eers vanaf 1,500rpm af

Michael, dis 'n beginpunt. Kan jy vir my een stuur asseblief?

Peter, al wat ek huidiglik kan kry is n kombenasie van n NA dyno grafiek met n ander voertuig se krag bo hom.
Die blou lyn is n NA TD42

Hi Peter,

Unfortunately my figures are not for an unmodified Patrol.

Herewith my 3.0Di (2008) pre CRDi motor's torque figures as at Jan 2018.

75mm exhaust,
300 x 600 front mount intercooler,
Madman,
SAC Chip
(at that stage with 265/70 x 17 tyres - 32's) - Tyre size makes a huge difference on torque figures.
This was after new injectors were fitted in November and a turbo recon done in April 2017.

After the above mods, these are my torque figures

RPM - BEFORE - AFTER
1500 - 192.3 - 306.3 NM
2000 - 293.2 - 362.0 NM
2500 - 277.0 - 342.7 NM
3000 - 245.8 - 300.3 NM
3500 - 235.0 - 267.7 NM
4000 - 185.3 - 205.8 NM

Pretty impressive Malcolm. Are those corrected for friction (ie estimated flywheel figures)?

No Peter, that was actual readings for torque at the wheels.
