So, went the dyno again... and here are the results. Now running; new Iridium Spark Plugs, breathing system cleaned with Catch Can and Oil filler breather, BWoody CAI, running Shell VPower and a custom tune by Yohan and Diablo.
1). Original factory Standard: 305.9bhp@wheels (estimated 420.7bhp) and 557Nm Torque (410lbs)
2). Post mods and Yohan tune: 328.4bhp@wheels (estimated 451.7bhp) and 583Nm Torque (430lbs)
That's a 31bhp and 26Nm/20lbs torque increase over my base figures! Power increases are not amazing, but around what I expected as this is just general maintenance and bolt-on.
The dyno calibration seems to show a really high 27.3% loss to the wheels when running AWD. That seems high BUT it is what it is. Plus it's the only 4WD dyno around here. So, based on the fact that most dyno's are not calibrated the same and I can only go off this 4WD to keep the figures constant.
Whether the figures are correct or not, this is the increase I'm showing, so that's as far as I can go this year. That's giving me a 12.99s 1/4 mile and a 4.52s 0-60mph using Draggy box. All better than the quoted figures so it's a result.
Think on a cold day and hitting it perfect from the lights, I think a 4.4s and a 12.8x will be as quick as this thing can go.
Super Charger next year
