Project MrBusa (Toyota MR-S / Hayabusa)

As promised here is a video of the cars very first run on the track….

We had the opportunity to turn some laps during the lunch break at a Classic race meeting so a good chance to finally give the car a shakedown.
It has a few minor niggles as expected, just things like some tyre rub & things, but overall a successful first run…

Yer we will have a better camera mount for its next outing. Weights in a bit heavier than we would have liked but still pretty good at just on 700kg

wowsers..thats just 50kg more than my old Westfield which was a bit of tube and a bit of plastic, come to think of it pretty much like your MR-S!! the downshifts scare me though, so worried she's gonna go pop..looks a LOT of fun though..!

Sorry its been a while between posts, but there hasn't really been anything exciting to report.... We have had two race days recently.

First was a Club day at our local Levels Raceway & we had the car seriously under sprung and over geared, resulting in me stalling in 2 of the 3 starts and in the last race I cooked the clutch trying to get started. Still posted a reasonable laptime of 1.07.332
Couple of pics here...

Second outing was at Ruapuna for the Premier Championship Series where we run in "Production GT" class on DOT rated tyres. A boost problem meant only 6th in qualifying, then a harsh call meant starting race 1 from the pit lane, but still managed to come through the field to win. race 2 was reverse grid and another win & class lap record of 1.31.519, but the boost problem came back for race 3 so just cruised round to finish. Happy with the results considered we haven't even started making changes to the suspension set-up yet, plus we were slightly undergeared for Ruapuna, meaning I had to get out of the throttle before the end of the main straight, plus I was struggling to reach full throttle (as the video shows) so a few wee issues to get sorted. Videos of the test sessions are below, the camera didn't work during the races :(

For those in NZ, the races from Ruapuna will be on the Gillette Motorsport TV show on January 8th 2012.

Outstanding! That car is a credit to you sir, that 20v turbo goes pretty well too!

Hi mate, what wheels are you using on track there, nice strong looking 5 spoke 5 stud just like the 70's ferrari targa florio cars with a bit of dish to them and I'm assuming light given the application!

Very nice going, goes like a mental thing :eek2:
With that setup I can't see it being too hard (or expensive) to change final drives to suit the track either :cool:

Amazing stuff - very impressive indeed! The last vid gives a good idea how much quicker you are than the others!!!
