Unless the "worked" engine has had it rev range increased it won't be any quicker than the cars gearing (diff & g/box) allows.

Increased power only gets you there faster. Gearing will get you a higher top speed!

I've managed a touch over 6300 in 5th back when I had 215rwkw. 6300 in 5th is ~245-250ish. So I agree a stock GTS25t would be lucky to push past 230-240 before it'd run out of puff or drag would stop the fun.

Pah... i got up to 190 in my stock standard R31 on "my private test track" and i'd say there was another 20-30km/h in it. Consider that is 120kw and an r33 gts-t has around 180kw standard, you should get more than 230km/hr.

Course with the stupid speedos on the skylines (whose dumb idea in japan was it to go up to only 180km/hr ??)... its always hard to tell.

Sure you can get to 180-190-200km/h etc.. but as speed goes up so to does drag. It's a LOT harder to hit 230-240km/h & takes plenty of power & a very good CD to push past these speeds. Plus add speedo error into the equation & you'll find your 190km/h in your R31 was probably closer to 175-180km/h.

I'd say for a box on wheels, an R31 would have massive drag!

Yeah, who knows about speedo error but generally i think mine was on target because i did a test once on the hume on that measure speed points and it was bang on at 110km/hr like the speedo was saying.

    • Aren't these run off of high voltage in OEM applications? Like 200+V. Or at least 48V in mild hybrids. At ~18,000 BTU ballpark nominal capacity the power draw is at what, 2.2 kW? ~185A is a pretty crazy amount of amps. At 200V it's only 11A. The 70A nominal kits with up to 100A peak draw I see for stuff like classic Porsches have pretty substantial compromises like shutting off at idle and not actually managing to keep the interior cool in hot conditions because they can only output like 6000 BTU. IMO if I had to pick what high amp draw component to retrofit to these cars I would start with the engine fan, not the AC compressor. You need an ~850-1000W brushless fan, something like this: I would love to see the data but I would bet that whatever you save by running the AC compressor in a more efficient regime with an electric motor you're probably losing to conversion losses anyways. It's not really like a clutch fan where you're losing power all the time even when it's nominally disengaged and it gets worse as it engages because the envelope tracking isn't that precise.
    • I am a volunteer marshal at the Grand Prix. As such, I get a "friend / family" ticket. It is a general admission ticket, valid for all 4 days. Anyone interested in my spare pass, please DM me. Ticket is "free, gratis and no expense".
    • agreed, the price vs gains it’s there.   unless you go china supercharger. Temu racing anyone?😂https://www.facebook.com/share/15nkfpsg7Z/?mibextid=wwXIfr that was one of the ones that popped up on my feed 😂
    • Bit of a long shot but if anyone has 4 of these laying around in new or near new condition. I will happily buy them off you.     https://skylinespares.com.au/product/stabilizer-door-glass-inner-new-8032404u03/?srsltid=AfmBOop6L5EgUFaHPHiVXoAhv5k8aJYwc77nGmoApp-hY03OiOsNVaOv Thanks 
    • I'm wondering is the Toyota and Mazda "collaboration" could see that new Toyota ???G20 ??? turbo engine that they have been showing off recently into a future MX5, apparently it's good for 400hp out of the box That could easily, possibly, be much better than the last collaboration between Toyota and Subaru with the boxer engine in the twins
