    I think its cool that the GT3 comes very close to matching the GTR's time while being a massive disadvantage considering it rear engine, rear drive, naturally aspirated vs. front mid, awd, same displacement turbo, oh and lets not forget the sequential gearbox.

    BTW, does this test GTR now have a void warranty. I'll take the pcar any day.

    Just saw that too! The part where he drives the small car inside in the BBC headquarters is classic.

    Excellent point. They would have had to run a nonstandard ECU to allow the driver to crazy things like use full throttle within 50 meters of a race track without going into limp mode.

    Aside from their cost I never understood why people race them.

    Ha, yeah, doesn't the GTR have a GPS in it which voids your warranty if it senses you do more than one lap around any known race track faster than 5/10ths?

    I do love it that they included a "feature" which automatically voids your warranty (launch control for those who don't know).

    13~14s arent that close, but it's not too far away for a 8-min course

    GT3 is one of my favorite cars but

    GT3: 435 hp
    GTR: 485 hp

    GT3: 3075 lbs
    GTR: 3814 lbs

    GT3: 235/305 Michelin Pilot Sport Cup (r-comp)
    GTR: 255/285 Bridgestone RE070 (street tire)

    i wouldn't call that massive disadvantage for GT3, even if you put GT3 engine in a Cayman, i donno how much it can catch GTR

    I think the gap is less with the new 3.8L GT3, mostly due to aero upgrades.

    Most GTR's put that much down to wheels stock, not to mention torque, so its safe to say Nissan fudged the figures in order to make themselves look better.

    Your standard GT3 weighs in quite a bit more than 3075, alot less than 3814, but not quite that low. Maybe an RS without radio or AC, but the cars used in most shootouts are equipped with AC and radio.

    The GTR runs its fast lap times on option Dunlops, the Bridgestones are way of pace.

    i don't think Nissan fudged the figures to make themselves look better, nothing proves that, their whp looks normal to 485 crank hp, people think 4wd should lose more than that, that's not necessary true especially GTR isn't all time 4wd

    also another things is even if GTR really has 520 on the crank, its laptime won't go much faster, that's not big enough to help laptimes dramatically on a car that already has 485hp

    i got both GT3 and GTR curb weight from their websites, it's up to you to trust them or not unless you show me corner weight # on scale

    reagarding the tires, you are right, i listed the wrong street tires for GTR when they clocked their fastest time, but it's not like GTR owners can't buy those Dunlop, it's also street tires, tread wear 200

    RE070 isn't that much off from Dunlop, unless you think 0.2~0.4s in 1 min long course is considered way off

    How would it not be way off? That would be a full second on a track as long as willow springs?

    wsir is 1.5 mins long, so about 0.3~0.6s off, where did your math find 1 full second?

    Lets say it has the least drive train loss out of any AWD car out there @ 20%, and they're putting down around 460 AWHP, that means it would be somewhere near 570. Its not enough to make a "huge" difference, but it all adds up.

    Having worked @ a Porsche specialist doing race prep, I have seen many 6 GT3's in many different specs. Most street cars are well over the 3075 figure, more like 3160-32XX depending on spec. I dont have any print outs and its not my business to post any of other peoples' cars. In regards to GTR corner weights. I have never seen GTR weigh ins, but I wouldn't be surprised if they're a bit less than published.
