Hi Brian, the engine and turbo sounds great - from the vid I can see:
1) some puffs of black;
2) you're running a snorkel;
3) headlights on...
Did you also record the runs on your AE? Given that there's black coming out my layman's thinking is that your fuel (HPOP and injectors) are pushing enough fuel in. Could it be the restriction in air intake?
How accurate is the dyno? Is it worth trying another dyno for a second opinnion?
For an extra 0.2 of a HP turn the headlights off
Lastly - was the dyno calibrated in KW and the graph using HP? - cause 398.8KW = 534HP - a 'funny' coincidence as that is about what you were expecting.
Certainly Bryan's seat of the pants review called it 500hp+ 3rd gear wheel spinning sideways etc...
The dyno was at PKW auto who is a well respected Drag racer and engine builder. I can only rely on he's expertise.
The "All Out" tune is gunna blow smoke, whether it be 400 ponies or 500. Thats what its spose to do. You really have to fuel em up to get those #'s
My laptop has **** itself so I couldnt get any AE data which at this stage is what I really need.
The main idea of the run was to get the HP cause I new from the get go I wasnt at the 500 mark.
Now that it is confirmed I can do the necessary test (once I get my laptop going) to eliminate either a lack of boost, drop in fuel pressure or a weak HPOP.
The way the curve flattens out sort of leads to either 3 or a combination.
Just put it out there cause peeps were asking for updates and I wanted to get the Youtube ****e sorted.
Im thinking of putting her on the rollers again once I have AE. It was only $150 for the run.
Oh, the headlights were on so he could see the instrument panel in the cab. It was quiet dark in that corner. And yes bro, it is in HP not KW.
If all checks OK my end then its back to Matt re the toons.
Brian: Looking forward to hearing what the issue is with the engine. When it's done you'll have to get your 'test pilot' there to give it another once over
Just one thing. A bloke was at work was telling me that US horsepower is different to Aussie horsepower. You can take about 13% of the US mark to get the Aussie equivalent. Any one heard of that. Maybe Adrian can chime in.
Heard of USA engines dynoed over there not making anywhere near the same hp here. Atmospheric pressure is different or something. Not sure, I was reading about shafiroff big block chev engines when I read it

G'day Brian,
I reckon we use the Metric Horsepower as the Standard International Unit.
That is 1 x Metric Horsepower = 735.6 Watts or 0.986 Standard Horsepower (US Horespower).
That is 1 x Metric Horsepower is 98.6% of 1 x US Horsepower.
I have read about the metric (HP) but I do believe the US also use the metric (HP) as well. As you quoted the difference is minimal. The guy at work was talking around 13%.
I know with the big European trucks (MERC. Scania, Volvo) HP is different to ours. Like a 540HP volvo will be 500HP here.
