What checks do you need to do before you know it is safe to turn up the boost or even just use what you know is safe on a different type of fuel? What sort of process do professional tuners follow when troubleshooting issues during a race weekend? This interview dives into these topics and much more!
Mike McGinnis of Innovate Tuning is also a High Performance Academy tutor and all round engine and transmission tuning expert. He knows his stuff and, luckily for all of us, is happy to share that knowledge at events like the World Time Attack Challenge.
The LYFE Motorsport R35 GT-R Skyline is no stranger to time attack or even this channel having been featured before here and also Pikes Peak. It has seen numerous changes over the years. At WTAC it ran a stroked 4.1L VR38DETT with twin Garrett GTX3076 turbos, Shepherd Transmission DCT with PPG gearset Dodson Motorsport Promax clutch and a MoTeC electronics package.
This GT-R pushes 1300hp on a Dynojet in the United States and 1120hp on a Mainline in Australia, which helps show that not all dyno numbers are 'equal' to the point they generally don't matter in the way most of us think, beyond being data for the tuner behind the laptop.
Owner Cole Powelson had his best WTAC event in the car, hitting a 1:25.9450, which put him third in the EMtron Pro Class and the fastest US driver to take a stab at the event over the years.
The car did double duty, with Donut Media KZfaqr Jeremiah Burton also hitting a solid 1:31.4800, which is more than solid for someone new to the car, track and speeds involved.
