Making no power...
Hey guys,
Recently brought another car in from japan, loaded with goodies...
However yesterday when I took it to the dyno to be tuned, it made pretty much no power at all..
Compression is good, makes boost fine (stable 1.3bar), air/fuel is good, timing is good, no ignition break up... but still only makes 200rwkw
After 5000rpm torque falls away, and it just stops making power..
Have replaced and checked tolerances on crank angle sensors, replaced plugs, leads, coils...

hows ur AFR? i had an issue just like yours, turns out a harness was loose by my Power FC causing it to richin up after 3500 rpm and i had no power whatsoever. sometimes it comes back but i just shake the harness around a lil bit and it works fine.

I'm going to pull the exhaust and downpipe off tonight and have a look. Maybe the center muffler has collapsed or something

Run was in 4th gear.
its a hub dyno, so eliminates the option of tyre slip.
A GTR skyline that ran after my car, made 500wkw so dyno certainly wasnt faulty

Possibly - altho AFR is consistent, and the injector duty/times are similar to my other FDs.
I pulled the exhaust off last night and found some sort of aftermarket cat behind one of the underbody shields. Decided its better out than in, so chopped it out. I will tig a straight piece of stainless in its place tonight.
It did seem to be pretty clogged up, so possibly the (or at least a contributing) problem.

Removed the aftermarket cat and tigged some straight 3" stainless in its place.
went back to the dyno and ripped out 347rwkw
Needless to say, pretty damn happy
