I went up with a big group from another forum i use ....... Really good day out! Few Skylines, Evo's, type r's and the coolest thing was Nissan Largo with an RB25 in it!

Works out cheaper if there is a group .... think it cost us £40 each

There is something not right with the 2 dyno runs. The first run shows 55 hp transmission loss then the next shows 32 hp loss, did they use different gears.

50 or 55 bhp loss sounds about right, add that tou your second run @ 163 whp.

That's sounds about right, shame it doesn't give you the torque at the wheels then you could work it out exactly.

Ignore the engine power figures, the only meaningful power a wheel dyno can give you is the one at the wheels, anything else is just a guess to try and give the customer a number. The only way to get a flywheel hp figure is to use an engine dyno.

50hp loss sounds way too high, I'd say 30-35hp would be a more reasonable estimate for a standard(ish) altezza. Also, the biggest portion of the drivetrain losses come from the tyres, which is a major variable, even in back to back runs, unless you monitor their pressures and temps and keep any strapping the same.

A hub dyno would get you closer to a more accurate flywheel figure as it eliminates the variable of the tyres from the measurement.
