Yes that dyno was a Mainline dyno which is known to break alot of hearts with power read outs. Yes i know what its like to race my car around a small track, its not easy (hill climb)
All my tuning is done in 4th gear, that run was stopped at about 190 - 200km/h. I only rev the car to 7000rpm because its a 3 litre and it only has a N1 oil pump which are known to destroy themself's when you rev them too hard. and stock rb25 balancer. at the track i rev it to 7200rpm
