Project MrBusa (Hayabusa turbo MR-S)

[Louie028]

As per the pics the MR-S has now had all its signwriting & graphix completed & even though the car itself still isnt 100% completed, it was good enough to have its first weekend away last weekend.
First had a photo shoot on Friday afternoon with New Zealand Performance Car Magazine




Then had the car on display at the 4 & Rotary championships, where we won the award for best engineering


And then to the drag racing on Sunday where the car was just on display again, and left on the trailer for people to see its nuts & bolts


Now we just need to finish re-mounting the reverse starter, altenator & make a modification to the front suspension top A arms & hopefully we will be ready for a dyno run/tune & then some testing!!!

Hey its been a while since this thread was updated as there has only been spasmodic progress on the car...

However the car was nearly finished enough to book for a dyno tune, so we booked it in at NZEFI in Christchurch, with the idea of it hopefully making its competition debut at a Street Sprint event on 14 May. Unfortunately they are booked that far ahead that this was looking impossible, until they phoned at 5pm one right with a cancellation if we could be there by 9am the next morning, so it was a rush & a late night getting the car finished & ready to go...


So it has been for its dyno run & we ended up with 372hp at the rear wheels, which is pretty good straight up... and there is still a bit more in the tank. and a pretty reasonable rev range as well



So the next step is off to the track for some testing, but both our local circuits only have one test day each between now & the Sprints (and the boss is away at Rally NZ for one of those) so it looks like we will only get one days testing & be taking a brand new car to the Sprints, of course providing that it performs Ok at the track!

Sorry there are no videos of the dyno run, but we weren't there for it all, I will try to get one from the track...

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…





and the video here…

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
