This event is to see who is the fastest (and has the highest top speed) from a standing start over a 1000m (1km) airport runway in an regional Australian town (Cooma, NSW – close to 1000m altitude). No race fuels, no nitrous, and only on street radial tyres.
This year the event was even better for my car, no ignition or major boost issues, I had a tune on e85 with some adjusted cam tuning, new tyres and the new turbo setup. More details on my build can be found HERE.
Well it’s been a while since I’ve posted up any info on my own supra. Unfortunately the supra and this website sometimes become lowest on the list of life’s priorities, but that doesn’t mean I’m still working on the supra – A man must have his hobbies!
Current power;
Tuned on pump 98 fuel with a result of 445rwkw (597rwhp) @ 23.5 psi
Tuned on pump e85 with a result of 482rwkw (646rwhp) @ 23.5 psi
Since the last update these are the major changes;
Titan 272 VVTi Camshafts, GSC Valve stems, GSC beehive springs and titanium retainers – hopefully a write up coming soon on installing these
Swapped out the old Garrett T51R SPL BB with a new Garrett GTX 4088R turbo with 1.06 rear. This was primarily to make it more streetable with the current engine setup staying stock for a while
Exhaust camshaft timing adjustments and slight vvti intake cam adjustment made by my tuner – this dramatically improved mid-range with the turbo by around 40hp – Exhaust cam tuning was 2 degrees of retard from memory
TRD Seibon hood removed and stock hood put back on to try and improve bonnet lift while racing at high speeds – although I still managed to brake another shroud at around 270kph (167mph)
Flex fuel sensor installed, although wiring yet to be setup and tuning to be complete
Tial BOV and other exhaust fabrication work for new turbo
Driveshaft shop single piece drive shaft, B series diff, Solid diff bushings to reduce axle tramp
Powersteering cooler setup in RHD duct
TRD sway bars and new links
New clamps for FMIC, fittings and ducting
Probably a few other things here and there that I’ve forgot about
Next in line will be cleaning up a few things I’m not 100% happy with at the moment such as improving intake temps. I will be installing twin thermo fans due to radiator setup and high speed racing causing shrouds to break – this will require some further intake fabrication work. Would like to create a custom airbox, install a fabricated oil catch can, changing to a new boost solenoid to allow for launch control/boost by gear and fix up some wiring.
New GTX4088R turbo got installed, managed to tap out a boost fitting and have a local shop do some fabrication work
The Titan 272 VVTi Camshafts, GSC Valve stems, GSC beehive springs and titanium retainers getting installed, I will be putting lots more pictures up and explaining this process in the near future
It’s been a while since I’ve posted anything on the site. Late last year was a very busy period in my personal life with some very large goals I’d set myself to be complete and I simply did not have time to spend on the website or any further content. I’d always rather post quality information on this site rather than quantity.
I will do my best to respond to all of the comments and questions over the next week or so and will be posting up some new content shortly.
