Calculated at 17.3 average loss on a manual transmission I got nearly bang on 250WHP 240WTQ..
TBH I dont think its worth doing a top dyno results for N/A as there are so many variables for such a little HP difference.
For example Mark got 270WHP and I got 250WHP - mine may have been done on a really hot day on texaco 95ron, strapped down really hard and marks may have been a damp morning and strapped lightly running shell optimax 99ron - I would have thought you can gain nearly 20hp in that alone. Thats not even taking into accound dyno and operator errors.
(I'm not saying that is the case, it was just an example)
p.s. Adams car is LUUUUSH
