Interesting... i did my one 300+ km per hr on GTR32 with few mods on the engine on it. Will like to try more in future :P

Is that using the stock speedo as your reference?

If so, its probably cloer to 250km/h the speedo would be out that far. ;)

R32 GTR....270 stock......Doubt it.

I reckon 240 would be a more realistic.....mines modified (315hp@wheels) and I'd rate its top speed realistically in the region of 240-250kmh.

Wheels mag tested a standard R32 GT-R at Lang Lang back in the early 90's, along with other cars, for the Top Speed Shootout. I recall the Holden engineers (who use the proving ground) said that tyre scrub around the curved track will cause a reduction of about 3-4% in top speeds.

The F40 there on the day could only manage 299km/h (they have been tested to 324km/h in a straight line), the GT-R 245 clicks. Factoring in that the day was very hot (obviously bad for the turbo cars), you would have to assume that the % speed loss for the GT-R and the F40 would be the same, so 245 X 1.08 = 262km/h

But, meh- who really cares.

I really doubt the speedo is more than 10% out probably more like 5%

If u can do the math thats no where near 250km/hr if the speedo is reading 300!

enjoy

Really who cares...Apart from the academics and bench racing aspects. Tuners use the 300kmh deal as a selling point or as "proof" of the potency of their tunes/part/philosophy/t-shirt - Top Secret, Mines. Same for vehicle manufacturers...Mclaren, Ferrari, RUF "its a supercar" Meh. It makes great youtube etc but its serious sh1t and these guys put big bucks into their experiments before trying the 300 "barrier"

My concern would be the effects of a component failure at 180mph+ it all happens pretty quick and you wouldnt have enough time to react..unless your a pro.

I've driven some fast and quick cars and I dont see the attraction of high speeds in an uncontrolled, non competitive environment, I guess i dont get it :D

Bah...I still say the realistic top speed of a stock R32 GTR is 240kmh...to quote anything else involves to much speculation about perfect world scenarios.

      Wheel Sizes & Offsets For Skylines

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

      MAJOR FUEL ISSUES 25det neo r32

      By MBS206 · Posted

      Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
