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.

      1/8NPT drill size = 8.7mm. Since the hole got messed up by me, it’s probably around 9mm.    So 1/4” NPT would be next step. A drill size of around 11mm would be preferred there which is not way of my M12 (drill 10.5mm and tap M12 threads)

      Why are you so adamant on going M12? Why not follow Brad (GTSBoy) suggestion. You're talking moving from a 1/8" size, to a 1/2" effectively. 4 times bigger. Why skip the commonly available sizes in between? The bigger you go, the more likely you are to strip the threads out at a later date, as guaranteed, someone will put a huge spanner on the M12 and really tighten it up, and you're only in thin wall, so not a lot of threads to engage!

      Hi. Yeah thanks. Car is already at tuners and it staying there to resolve "many" issues they do not like. So it is in a good hands. Getting a good tune on that Nistune ECU too so the car would be good. Just needs a little tune up and love.

      Probably gonna remove manifold and turbo. I’m not sure if I can get M12 x 1.5 air tight. Could use high temp Loctite 246 or something similar, but I don’t know. Maybe it’s just best to remove everything again and weld an 1/8NPT on there instead.
