Unicorn Motor Developements S3 Stage 1 Dyno and Vbox Results

Maybe they were running different fuel, V power or similar makes a good difference in these doesn't it ?. Post map torque and power look to be falling quicker at 2500 rpm than the pre map lines. This isn't the same as the S3 dyno run which seem to come together at around 2500 rpm.
Is that just due to the way the dyno run was done ?.
Still as ever very impressive improvements on standard hardware.
 
Pre map run would have been started a 100rpm earlier perhaps - we're not too concerned with such low RPM on a petrol :)

Fuel is a good possibility, the R was on VPower for sure, the S3 uncertain.

As good as V-Power Nitro is, it would not account for a difference of 23 bhp! ;)
