Man, what a day, I wanted a scarey ride and I got it
Note to self: DO NOT REMOVE REAR WING AND GO RACING!!!!
Took the 240z to a test and tune day yesterday and I hadn't give a second thought to the removal of the tiny little duck tail wing from the rear hatch while the car was re-painted, big mistake.
First run, take it easy I thought, 1.7 bar, little bit of NOS on the transbrake only, leave with about 10psi boost, and HOLY FU*K what a ride, the shift light was on, off, on off, on, off, on, off the whole way down, we had 9300rpm in top gear at 1/2 track and I've never felt wheelspin like that before, had to pedal it like it was on ice, even through the finish line it was all over the track. Down right nasty.
1.45 60ft, 9.7 @ 123mph
At this stage we hadn't clicked that no wing was probably most of the problem so we dropped the peek boost to 1.4 bar, let the tyres down a bit and decided to roll pretty slow off the line and ease on the power more progressivly, still wheelspun most of the way but I got some grip around 1/2 track and then massive tyre shake towards the end and had to back off....1.50 60ft, 5.8 1/2 track at just 125mph and then 8.92 @ just 156mph.
An official at the start line commented to one of my guys "tell him to get a wing on that car before he kills himself!!" Obviously drifting the whole 1/4 mile was not what they wanted to see, lol.
Did another run, got way out of shape at about 1/2 track and rolled through for a 9.7 at 113mph.
Anyway, the more we tried the slower we went, even went up just 1psi of boost for another run and wheelspun the whole way, getting WAY out of shape when I gave it a bit more throttle at about the 300 meter mark, thank god for parachutes, I crossed the finish line at 151mph totally out of control and I tell ya, that parachute saved my ass, no question about it, straightened me up instantly.
I'll download some video's shortly and link them.
I can't wait to have grip back again so we can hopefully wind her back up to 2 bar
