Outer Limits 4x4 Board

put my truck in for a tune, looking for some more grunt they say its good for a standard 4.2td ,is there much more power in standard form without the risk of blowing it up 99kw [135hp]/3120 rpm and362nm /390 rpm , at 110 kilometers 82 kw ,2990 rpm ,8.6 boost tyre size 265-70-16 doe not state egt

what year model mate

Check exhaust temps with pyro, in my experience on an accurate dyno at 99 kw you will already be way too hot.
If you want more power you should be looking at intercooling, more efficient turbos and bigger exhaust to help reduce heat.

2002 gu111, im having a go at dyno phots should work it out soon

how fast do these nissans go took it up to 130ks didnt have much left the dyno says 99 kw at the weels these motors are suppost to have 114 kw at the flyweel and 360 nm dyno says 99 at weels and the nm are the same as stock it it me or this does not ad up

A couple of things, you have the same or higher torque reading because of a gear reduction at your diff. 99rwkw is not standard power figures at the tyres. Either the tyres are slipping or theres a correction problem.

Most fact gu td42t patrols we have dynoed run between 62-80 rwkw. This is with them strapped down so they dont move off the rollers. You can get more power if you only run the front roller.

Hope this helps, can even post a dyno sheet if needed.

Yes I agree 100% with Dzltec on those figures, the upper number being one with the fuel adjusted. Although I strap my vehicles down the DTS dyno has a belt connecting the front and rear rollers so that the power dosent change as the car rides up the front roller, when you have 250 kW and more no amount of strapping keeps the buggers down.

thanks for the impo ,looks like i waisted my time and money

is there anyone in perth that can do the job or i have a mate i can trust he can check the timing and ajust it if required
