R.I.P.S RB30 runs 8s with 1.4 bar, street tyres, gasoline, no NOS

[R.I.P.S NZ]

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

Glad to hear the car is one piece even if you need a new race suit.

There is a lot of negative pressure on the back of Z - hence why they drag in so many fuel fumes through the hatch. You might need a bigger wing than the duck tail now!

Looking forward to the videos and well done on the new build.

Well done mate. Sounds like one of those fun days out

[GTaaaaaarrrrrr!]

Nutter Can't wait to see your clips mate

LOL @ you Rob, absolute madness

Did it wheelie at all, or just spin the tyres instead?

Yeah, we'll definatly be putting a decent adjustable drag wing on the back but it shows the old duck tail must have been doing a fair bit.

I was hoping not to have to add any more weight though as we are already more than 210kg heavier than the 2 RB30 powered tube cars in Pro Import I like to compare myself with and will be racing against (they are both only about 10kg over minimum weight) but without a wing we'll not be going any quicker anytime soon and its a safety issue as you'll see when you see the vids, lol.

I found the track slippery at the start line so it basicly wheelspun all the way, didn't see the front lift at all on the vids, as soon as I grabbed a gear the shift light was staright back on again so I had to pedal it big time to keep it off the rev limiter.

Lots of fun and it sure made me concentrate but looking at some of the footage it could have turned nasty pretty easy.

One guy in a pretty low powered skyline lost it at about the 100 meter mark, crossed lanes and hit the wall hard on the other side thats how bad it was.

x2 Rob, said hours ago I need to see the vid - still waiting!!! :P Awesome to hear its all happy and in the relative scheme of things there was no drama. Should be awesome to see how it goes with a decent wing on it! Put the duck tail on and come to Masterton this weekend!

Definitely sounds like that track was a bit dodgey, though the mind boggling thing was the Rayglass Celica managed a 6.9s run! They had to dial the power way back etc before hand though, the car is pretty much set up to break records on the right track at the moment.

Sorry Boss!! lol

Youtube was real slow

Did you forget to turn the 4wd back on

Crazy stuff mate. Always at the very top on the track aswell?

[Boosted]

That thing is making serious power

Rob, I think you should paint it black and put horns on it, it's definately the devil on wheels. Then you need to get that guy from New Zealand Performance Car to come and have another go in it with you. I'd love to see the look on his face when you floor it

Bloody hell. Nice work keeping off the wall Rob, and yeah she really looks like it needs some aerodynamic help. Sounds really really nice!!!
