For those who haven't read it, I still recommend you do.
They touched alot on the handling and performance results.

oh, those drag times were on the stock LSD right?
thanks man, I'm just curious about everyone's real world FI driving experience
BTW, really big fan of your car

does anyone know the specs on that motor? i'm curious as to what they are doing with the block cooling issues (i assume it is a vq35?!)

To the best of my knowledge when they made that pass they were running a stock VQ block and crank. Block was sleeved... Stock cams, valve springs were swaped out... Other than that the heads are pretty much stock. Obviously rods, pistons and bolts were changed (I think corrillo and arp not sure about the pistons). 1000cc injectors / full MoTec / Stock intake manifold. Two big as# turbonetics turbos, currently switched to borg warner tubos (I didn't even no they made turbos) / ice/water intercooler...
As far as heating I think they may have a fix, but a lot of things there are hush hush

Heres some info on it.....
The 350 relies on a beefed-up version of the mighty VQ35DE powerplant for motivation. Outfitted with JE forged pistons and Carillo rods, the 3.5L had its compression dropped to 10.3:1 in order to allow higher boost levels; and its rev limit raised to 8,000rpm to help keep the boost pressurized throughout the curve. A Nismo R-Tune camshaft, valve job and mild porting of the exhaust ports by Headgames are also features of this build-up.
Last year, the car was set up with two different nitrous setups – a 300 shot and 375 shot that helped the team go through two engine blocks. This season, however, reliability issues prompted them to switch over to a Power Enterprise twin turbo system, which features a PE exhaust manifold, 2.25-inch down-pipe and modified air-to-water PE intercooler. The wastegate is internal, but the HKS blow-off valve is not.
A large 75mm Accufab throttle body translates the air into additional power with high-flowing Bosch Motorsport injectors transporting loads of additional fuel from an ATL 15 gallon fuel cell. A 240gph Weldon fuel pump and Aeromotive fuel pressure regulator and filter help out with the task.
Engine management duties are performed by a MoTeC M880 system that gives control over the fuel and ignition as well as closed loop wideband oxygen control and datalogging for a number of inputs. Before Ioannou, who knows MoTeC systems like the back of his hand, came on board, the team found tuning a challenge.
“We feel we’re doing pretty good considering we’re the only ones running this V6 right now,” defended Rubio.
Drivetrain upgrades consist of a custom made Unorthodox Racing five pound aluminum flywheel that works in conjunction with a Tilton multi-plate metallic clutch and the factory 6-speed. A Nismo LSD with a Nismo finned differential cover helps distribute the power equally to the rear wheels.
Tein Flex coilovers all around provide ample adjustability for fine tweaks on race days thanks to the EDFC system. Weld 15x9-inch aluminum rims house BFGoodrich 275/50/15 drag radials on the rear axles while the fronts are 15x3.5-inch skinnies with 26x5-15 Mickey Thompson front runners. BFGoodrich came on board as a sponsor in June.

Since that quote, it's changed to a "funny car body." It also uses a custom turbo setup now (actually, I believe they gave up on the PE at around 600rwhp). BTW, they are the world's fastest 350Z with VQ35DE and the first in the world to do 12's, 11's, 10's, 9's, and 8's in a 350Z. Another BTW, there are quite a few upgrades that aren't mentioned in that. Like the Driveshaft Shop rear axles, carbon fiber hatch, etc. (though they are not using the hatch anymore since it is all fiberglass (the funny car body)).

I've been around the silver Z alot... They have the nismo LSD, Tein Flexover Suspension / They have aftermarket axels / GT Spec lower lateral brace / turbo 400 tranny / Full Roll cage / Car is around 3000 including Andrew...
late
I was in the shop late last summer when I first saw the 8 sec vid, and I couldn't believe how well the car hooked! Vinnie Ten said the Z hooks a lot better the Supra ever could. That's saying alot from Mr. 2JZ him self...
Not bad for a street legal 10.5 inch drag radial...
Jayson from MRC runs a DR with the same axels and an lsd with 398 whp APS TT a very heavy car he is around 11.5 @ 119

You are talking about two different cars running in different classes. The silver car with the carbon hatch that ran 8.3@176 runs in the pro street tire class in which only minor mods (see carbon hatch) to the body are allowed. The orange fiberglass "funny car" you are talking about is a Peformance Motorsports car but runs in the pro RWD class.

When talking to them last week, they said they are running custom ground cams with "Top Secret" specs/durations. The pistons are CP's that they have custom made and use Carrilo Rods.
I wonder if they moved the engine further back to assist in traction? Would require lots of fabrication, but they may have.

I don't know anything about those 1/4 mile times (other than that they do look slow), but some of you guys are missing the point of the sidebar regarding the NA Z that beat all the turbo cars' lap times at Streets of Willow. That car wasn't actually part of the test. It was there because it's Mike Cronin Jr.'s personal car that he uses to do lapping days for fun. He drove it out there to the test. It was an interesting sidebar, and that's why it was presented as a sidebar...all of it's numbers weren't stacked up in line with the cars in the test. The point Dan Barnes (the editor) was trying to make by giving Mike's lap time for his personal car was: "if you want to run fast lap times on a road course, big power isn't the first place to look." Suspension, brakes, and tires will get you more on a twisty road course than lots of HP. Weight reduction would be a better route than big power. That was the editor's point of showing what Mike's car could do.
Sidenote...
During my suspension testing with Unitech racing, Mike actually turned a 1:27.29 in his car (while I was watching) using the Unitech Koni/Truechoice coilover setup (about a second faster than he could muster with the S-Tune kit. He then turned a 1:28.51 in my car which has a few less mods and is NA (with the Koni setup). He is an outstanding pro driver, and he knows that track extremely well. Nobody should doubt his skill, that much is for certain! I have no idea if he did the driving for the 1/4 mile segment of the test.
