3 rolling start drags. 3rd gear. R31 RB30E vs R33 GTS RB25DE

R31 : 3

R33 : 0

when we both got a good start it was VERY close.

Didnt rev the 31 over 5000rpm (power dies off)

31 - extractors exhaust panel filter butchered airbox and timing, no rear seats/speakers or anything in boot.

33 - extractors full exhaust and maybe a pod, full interior.

Very wierd, didn't expect that result.

I reckon he would probably take me from a standing start.

:uh-huh:

hehehehe maybe we'll have to test the standing start theory, but yep slip definately had me all 3 times. My car has extractors highflow cat hks super drager zaust and a slightly home tuned safc oh and a k n n highflow panel filter. And i didnt have my boot install in at the time which also slows the car down alot!! id hate to think how bad it would of been if it was in there. Damn car.... I wont have it back till next week now, oh well maybe with the cf bonnet it will be enough of a weight reduction to beat u!! hahaha i call a rematch!

P.S. I was giving it everything too, flat changing at 6900 just before the cut out.... ah well....

:)

What's the factory weight of the R33 GTS as compared to the factory weight of our R31's? the GX R31's are about 1300 or so (bit under maybe?) from the factory If I remember correctly?

Is there much weight loss to be had in stripping that stuff out Slip? Oh, and a little off topic, but how do you remove the R31 back seat?

cheers,

floody

Hmm i did a 15.409 @ 87mph with stereo and the spare and jack in my 31.

Exhaust, Extractors and a pod filter, 20Degree's timing, but thats it. It's a Silhouette 5speed.

Im really suprised with these results too slip, on ya mate.

not bad not bad at all! im not a suckup benny boy :D i just thought R33 GTS would be quicker then an R31, hence why a better driver in an R31 makes it quicker some how lol, well all i can say is i beat an R31 gts turbo around morgan park, over took him a few times!

chaos - was done on a closed road.

Dont think driver skill came into it, as there wasnt any noticeable change in position when we changed gears.

My car sucks off the line, bigtime.

No 0-100m or 1/4 mile times, probably 15.4-15.9 between timmay and jason's times.

Weight wise - towbar 15kg, 6x9's, rear seats 10kg, spare/jack fair bit. Dont know really.

floody - grab the rear squab and just pull it out. Undo the 2 bolts either side of the bottom right of the backrest. Then fold the middle of the backrest down so you have access to the boot, and right down the bottom there are 2 x 10mm i think nuts holding it on. Lift the backrest upwards as it has tabs in the rear parcel shelf, then pull it out. Done.

Would be interesting to see how the VL 5 Speed compares.

It runs a higher ratio diff compared to the R31's.

VL 3.45 -------- R31 3.7

Origionally my VL had an Auto in it, stock with a little bit of timing it made 90rwkw. It did used to go pretty well for a stocker and was very clean so maybe it wasn't thrashed. Once up and rolling it used to be exactly as quick as an auto 5ltr V8 statesman (VP) shape.

I then had the extractors and 2.5" exhaust fitted. I didn't dyno it but it used to suck the doors off a VS series II Eco-tec thingo and keep pulling. I also ran an Auto VR 5ltr and by 100km's he was at my rear bumper.

The Manual made a huge difference to off the line acceleration. With only stalling it up slightly it would easily wheelspin.

Towards the end after I had done around 60,000km's in it and clocked up 230,000kms it had started to not want to spin?!?! Was thrashed i'd say.. :O

Was a good car.. Nothing broke, bit like the R32 I guess. :(

I traded it in for a VS 5ltr that had Pacemaker extractors, 3.5" exhaust, chip, bilstein adj. suspension and believe it or not it wasn't that much quiker in 1st gear. 2nd gear it used to flick through pretty quick and by 115km/h and change in to third it was much quicker. I ended up having heaps of trouble with that car every part of the drive line including the rear IRS chassis broke. :P

Sold it bough the Skyline. Best car i've owned.

ive beat a hell of alot of manual vl commo's, my best friend and i actually had a proper standing start race and over approx 400 meters i beat him by 4 car lengths and also roll on my car shits all over it so slips would probably kill one.

Depends on the condition of the VL also as they are getting on now.

When I sold mine it was stuffed it really struggled to wheel spin. Didn't blow any smoke though. When I first got it with the auto it would sit there on the spot smoke first click second and spin second right up sitting on 120km/h on the spedo.

Stalling it up right on the edge would also make it wheel spin all the way through first with 215's on it. I could never find the sweet spot of launching with the auto as it would either bog down and feel like a rubber band gearbox or wheel spin.

its all about torque....the 3L will always pull away from a 2.5L, with atmos its all about cubes. but the RB30 wont rev to 6500rpm like the RB25, which does it so easily. but the RB25 doesnt have the torque to pull the big 33 around as its designed for a turbo 2.5L and even though the cars way roughly the same, the RB30 is better suited to the 31 than the 25 to the 33.

my R31 will get my brothers R33 GTS-t until he hits boost...then its all over.

cheers

    • Didnt realise RB's had more then 1 head.
    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
