Its always nice to tune 2 of the same model of car on the same day and do some baseline research. Things such as making comparison to engine compression, actuator strength and status when independent boost control is switched off. Analysing and comparing exhaust systems, breathing, intake, temperature, even asking the drivers who’s running which oil.
Seems as though this EVO 7 got the better of the younger EVO 8 on this first outing. Im expecting to see both these cars back at the workshop for further medication in the form of uprated cams and pulleys and then back on the dyno for some breathing optimisation.
Great power for an old EVO 7. As always the 4G63 in its stock form is a fantastic car when boosted and tuned with what is effectively basic bolt on modifications.
Another happy EVO owner
