i would say its a tad low, you should atleast expect 120rwkw minimum. but i guess it all depends on the dyno, the km on the car. ect

it made that at just over 4000rpm. When im drivin, past 4000rpm it feels like its not pulling nearly as hard as like 3000rpm. Thinkin that its because of the standard heads and exhaust manifolds

Check that the accelerator cable is opening the throttle blade all the way with the throttle pressed, its common for the cable to stretch over time.

I would expect an old smoky auto V8 to pull those kind of numbers, but not a manual which I assume all the usual wear and tear items are in good order (leads, plugs, filters etc)

Your power is way down, and 4000rpm is low for a maximum reading. A good stock 5.0 should be around 140-145rwkW @ 5000rpm. Something's not right. As to what the problem is, you just have to work systematically through the possibilities - dyno, engine mechanical, electrical, fuel.

My stock as a rock eb v8 with 300tho + kms pulled 108 for its final figure was around 112 with 320nm but averaged out came up as 108rwkw and 300rwnm @ 4150rpm - 100% stock no mods and a/f was 12.5.

Capares 5speed pulled 127rwkw @4150rpm with just a full exhaust system, then 160rwkw with a manifold swap (rpm2). He had an a/f of 13 i believe but it doesn't ping with good petrol ie 98ron.

pretty hard to guess whats potentially wrong off just a number, it could be one of a million things.
post the dyno sheet, could even just be a low reading dyno.

My stock eb xr8 motor in my ea made nearly 137rwkw & 345nm and its manual too.Its got a crap 2.5'' exhaust and K&N panel filter.Im not sure what the timing is set at but reckon it could do with a few more degree's too...and its got 139k on the engine

Mine made almost 122rwkw on LPG without any mods and that's through the auto box. Above 4000 not much happens, but Ford didn't make them to rev like a racecar despite the XR name, more for towing a trailer with plenty of low down torque. V8 in the EF series was the same across the range with all the same running gear.

Mainline dynos dont give generous readings if thats what it made then thats what it made...

Look dynos are more for tuning cars and at the end of the day it 'estimates power' as long as the tune is good i wouldn't worry about the low reading power figure.

Atleast now you have a baseline to start with.
