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

It'd light em up pretty much anywhere down the strip but with no wing on the back the faster I went the easier it seemed to spin the tyres.

The 8.9 at 1.4 bar still wheelspinning alot gives me a kind of uncomfortable feeling its going to be pretty damn cool once wound up with some grip, it was about 10mph down at 1/2 track on the 8.9 and at 1.4 bar the turbo isn't really even getting started.

that was certainly an interesting watch, i knew it ended with no accidents but i still watched that first one on the brink of tears!

that is certainly some tail sliding going on up there!

makes you realise how those big ol wings really do help!

obviously the better the drag coefficient the faster you will go but if there is no grip then it is suicide. a happy medium is what you need! any access to a wind tunnel? lol

[plumwerks]

First up Rob,glad to see you kept it shiny side up,secondly holy sh_t man,damn.
So now get the wing on,double check the rear settings and get your ass back out soon.We wanna see air time.

[Ludders]

That is a monster you have built there!!! Keep it on the black stuff!!

A bit squirrelly Rob! You nutter.

Was the track temp low? I think you are right about the aero:d needing working on and I think the extra weight will be more than compensated by the fact that you will be able to keep your foot down!

Must be an 8.5 in there with the power up Rob.

Yeah, I've never had to pedal the 240z before, its always had plenty of grip and it took me by surprise actually, on the first run with 1.7 bar I couldn't work out why the shift light woudn't go out when I changed gears, lol.

On the 8.9 run it was at 1.4 bar, no NOS and I was still pedling it quite a bit, especially in the top end, the mph was about 10mph down at 1/2 track due to rolling so gently off the line and wheelspin so the 156mph could quite easily have been 165-166 at 1.4 bar with a good 60ft and some grip.

The power difference between 1.4 bar and 1.7 bar is considerable so if I can keep it fully pegged with the boost up a bit and get a decent launch, its gunna be one hell of a ride and I don't have any idea what it might be like with the 2 bar we use to use, then add NOS to that as well, don't really want to think to much about it tbh just going to have to wind it up slowly.

Now do it in a GTR, and get mods to move this to other marques

Now now, come on Smokey its an RB engine suitable for a GTR.

It still weighs more than some of the UK pro GTRs and the 60fts in these runs are very slow so its actually a very good indictaion of what the motor would do in a GTR.

Mods can move it if they think its not relevant to skylines.

P.S Its actually a R32 GTS with a different body kit

So what would happen if the motor was transplanted into a GTR, and ran 8's?

Would the doubters then accept that RIPS motors can do the business, or will downhill dragstrips and different air come into play, again?

Don't forget there is only 10 inches in a NZ foot !

I forgot that, thanks for reminding me Ludders. Also, I just remembered that they get one of their mates to throw a crisp packet through the timing lights while the cars are about half track. Those magical 8's are easy with the 'right team'

I wouldn't worry about it mate, its obvious that the 240z motor doesn't rev, makes no power, has a poor reliability record and couldn't possibly propel a same weight skyline to anything like the same times or mph even if we did wind the boost up to the same level as the other guys run, anyone with 1/2 a brain could work that out.

Actually, wouldn't it be intersting to turn some of their engines down to 1.4 bar peek on the same fuel as we use, get them up to the same weight, get them to do a 1.5 60ft and then see how they get on, it might give us a good idea of how much we need to improve.

Any idiot can see we arn't even close to these guys mate.

Very nice work Rob, keep it up
and never mind the dis-believers

[Daz]

Well done Rob..I'll be keeping an eye out to see how quick you manage to go

[R.I.P.S NZ]

We've finished the wing and it'll be interesting to see how it goes, we are by no means "wing experts" and basicly we looked at alot of pictures and got some basic guidance from a couple of guys.

Hopefully we get some grip and can start to wind the power back in,
