No offense, but I own both an IS-F and a C6 Z06, and my Z06 is so much faster that it literally runs away from my IS-F... the IS-F is a sweet & quick daily driver, but let's be real. Frankly the IS-F actually feels kinda slow to me.

I think you've been smokin too much of your own stuff... frankly I'll see next time I take it to the track which one is truly quicker... there really is no basis to your statement though, as there is nothing to do to "handle" an IS-F. It's a plainly simple car to drive fast, where as the Z06 is much harder to control as it can easily have too much wheelspin & slow the launch. I have several cars that I track & occasionally act as driving instructor for some car clubs, so I'm sure you must be a much better driver with your IS-F...
Please, just stop dreaming... the Z06's can run high 10's in the quarter, and the best time for IS-F's is high 12's. Like I said, the IS-F is a sweet ride & it is fast, but it's not _that_ fast. I suppose you think it can beat a 599 too? Maybe your buddy needs to learn how to drive his Z06 if he couldn't beat you by much... Your opinions can't change facts or the laws of physics. Let's see, a lower HP/Torque car that's heavier, with smaller tires, can beat a car with much better HP/Weight ratio & has been proven quicker many times... hmm.
So now some more data to the story comes out... you never said you got a jump on him the 1st time. At least that makes more sense, but if he knew how to drive & launched anytime close to your launch he should have caught up & passed you if you ran it for more than a block. He probably saw you get a jump on him & over reacted, got too much tire spin, then when he finally hooked it took him longer to catch up. And the laws of physics are what governs how any car goes, so you can't really have one without the other. But that's also why I don't place much credit in street blasts, as it's tough to know how it really goes down. Many times it does turn into the luck of the draw & who goes first. Somewhere near me there's probably some punk kid in a Corolla that thinks he's as fast as my Z06, since he was trying to pass me and I just gave it just enough gas so he couldn't, but not enough to pull ahead of him. Other times I just hit the gas for about 3-5 seconds and I'm so far into the "arrest me now" zone that I lift & brake... then the other guy goes flying by a few seconds later. Does that mean he's faster too? Cause he can pass me after I'm slowing down after I put 5-10 car lengths on him?
I'm sure that will be one h**l of a kit! On the street that should give anything a run for the money. But on the track or any kind of sustained use, where you open it up for a little while I don't think it will be as fast as you think, or as fast as the ZR1. Remember that thing is conservatively rated at 638HP and 604LB/FT of torque and is approx 600+lbs lighter than your IS-F will be with a s/c. Physics still applies here too, and A=F/M, so his greater force & less mass wins. It also has larger tires for better traction. The only real chance you'll have is to catch him in the wrong gear since the IS-F auto will downshift reasonably quickly.
Also, even if the TRD kit makes 625HP (which would take around 8-10lbs of boost), how long do you think the cast pistons of an 11.8:1 engine like the 2UR-GSE in the IS-F will handle that? Everything I've seen says the pistons are cast, so you really can't push it too much with boost. That kind of peak power will have to be short lived. They will have to pull it back to keep the engine & the rest of the drivetrain alive. But I'm sure it will make for fun street blasts!
Don't think I'm slamming the IS-F... heck, we just added one to our small fleet of cars, I just want to keep it real with the claims. The IS-F is a very fast & cool ride just as it rolls off the showroom floor. The simple fact that it's a toss up as to whether an M3 or IS-F will win at most any given track event is a great compliment to Lexus, especially for a first effort. There's no need to do more brow beating to hype how fast it is. Someone else will always build a faster, cooler car next week, so just enjoy the ride!
Maybe you should take a few engineering classes & build a few race engines like I have & you'll see how long a cast aluminum piston lasts in a forced induction application... especially when pushed enough to make a "target" 625hp when starting with 11.8:1 CR like the other poster said.
And yes, I've seen the titanium intake valves & forged crank & rods. Nice...
Maybe you should also learn to read, as I clearly said C6 Z06 in my first post. Since we were all talking new cars, it would have been assumed by most you were talking about the C6 Z06. If you're talking the C5 Z06 which you didn't mention until now, that's a very different beast. I have no trouble passing them in my C6 on the track.
Only C6 Z06's I can't pass on the track are the modded one's with 600-660+ HP! Which BTW only takes a cat back exhaust, cam & tune.
How much crow would you like to eat? I can have a buddy scan & send a couple time slips in the high 10's BONE STOCK... the driver just has to know how to DRIVE a powerful car. 11's are much more common as you noted, which is still awesome for a stock car thats can be had for $70-80k.
I also agree that comparing these 2 cars is insane, and that was the reason for my original post. The other party claimed the IS-F was basically faster than god, and though it's fast I had to call him out as it sounded like another person with limited experience claiming the unreal was possible.
I absolutely agree that a regular C6 against an IS-F would be a drivers race as it's easier to control the IS-F, where the Vettes can get heavy spin if not launched correctly.
BTW, if you think all the 10 second time slips for Z06's are doctored, then you're even more of a skeptic than I am. I have seen 2 that I'm 99.99% confident in being real. Whether you buy it or not, matters little to me. I was just pointing out the truth that they do exist.
Oh, and there's also plenty of carbon fiber on the Z06, not just fiberglass (which is really not regular fiberglass, but SMC). And let's not forget the aluminum chassis, magnesium sub-frame, titanium rods, valves, etc.
I agree, the IS-F does work better for a daily driver... that's what we bought the IS-F for. I'll probably track it a few times just for grins & I bet it will do just fine. Then again I also have the other vehicles from Britain, Germany, and Italy in the garage if I want to have fun in other ways. I'm not locked into one brand or country.
Point is, all the blind loyalty to "one brand is best" is silly. They're all cool cars & many do different things well. I readily admit most GM cars suck (as do most American cars) and I wouldn't own the majority of them. The Z06 is one exception (and it does more than go fast in a straight line as a guy in a F430 and another in a GT3 will admit after my last track event). I have no particular "brand loyalty" that blinds me. My next car could be a GT-R, Porsche or Lotus if the car feels right to me & fits the right niche. For a street car that you can take right to the track with minimal prep, I've seen more Z06's run fast, reliably, than anything else. So I bought one. That's all. It is a great car to drive as well, even if it's only to work once in a while.
So does that mean I can't drive a Vette since I'm under 40 and have hair on my head & not my chest???
