On this nice spring day in Southern Louisiana we had the chance to calibrate this manual transmission Infiniti G37.
This vehicle came in thanks to the referral from Christopher, it is always nice to have a client that is knee deep in the local street race scene and sends clients our way from time to time.
So with that said in comes this 2012 Infiniti G37 with 159k miles on the odometer.
Mods on this vehicle were only Stillen Gen3 intakes and a test pipe. Everything else was stock on this vehicle.
Ambient conditions on the day of the calibration, 76F, 59% humidity and 30.31 baro. All runs were done in 4th gear.
Blue line is the baseline run – 273whp
Green line run – is where we hit a wall and could not gain any more WHP. At this moment is when we started checking things as spark plugs, oil level (once again) and even called the client to ask him how many miles the engine oil had. One of the indicators on the datalog was the intake cam adv. was reporting some odd numbers.
We were told that he did not know how many miles on the engine oil, so we did a oil flush and then added fresh oil and filter. When it comes to lubrication of engines no better brand than Amsoil as we use that brand in many of our client’s vehicles.
Red line run – is immediately after we changed the oil and no changes were done to the calibration from the Green line. The power of proper lubrication in the internals!
For all you dyno jet people here is the chart in comparison mode, before and after results.
