Vortech "G" -VS- 3000GT VR4 ???
Who would win in this match up? The "G" with a 3.12 (9.5 - 10 psi) pulley puttn right around 400 to the wheels... The 3000GT being AWD and TT w/ a boost controller pushn 'round 15-18 PSI, otherwise stock...

Off the Line the Vr will win
Those things are awesome if he has the basll to dump the clutch, and do it right
It wiill be close though, so go for it...
If you win its unexpected!!

stock VR4 is 9 lbs making at 320hp/315tq
they're pretty heavy cars though weighing in at around 3700-3800+ lbs stock, but they stilldo 0-60 in around 5 seconds stock, and quarter mile at around 13.8 sec average
they're also going to have a lot more torque than a vortech G35. Even with 9.5-10 psi at redline that you get just as you reach redline, it won't be enough to go up against his constant 15-18 psi, even if it is a smaller 3 liter engine
their gearing isn't all that super aggressive though, but unless he also has an automatic, he could have the advantage unless he messes up his shifting.
but still my money would probably be on the 3000GT VR4 considering G35's are in the 3450 lb range stock, especially if you added an 80 lb FI kit, a BBK, and stereo to the G. I think he'd win the 1/4 mile by .3-.6 sec or so

Well, I'll let ya all know how it turns out. I am planning on running him tomorrow night. It will be video taped and put up on you tube and streetfire. I am going to take out my 2 subs and 2 amps to try and lighten my load a bit.
Should be a good run none-the-less.

Yeah booger, I ran a 380 on a Dyno Dynamics which (what everyone tells me) when you add 10% brings her up to 418.
TQ hit 310 (310 + 10% = 341) @ 4700 rpms and holds to redline.
I am definately not taking this car lightly.

If that is all he has, you will win from a roll, fairly easily. The stock turbo's on the VR4's suck. He may crank it up to 15PSI, but they only hold 10-11 PSI to redline. So this guy just has a boost controller as his only mod (no exhaust, downpipe, intake, etc). Doesn't make a whole lot of sense.

I had a stealth, basically same car. My zr with vortech and 3:12 would cream my stealth, not even close. Considering he has a lot more boost, I think it would be close. f you get a good launch you will win.

I am not sure what else he has, if anything... I do not know him nor have I seen his car... A friend of mine w/ a NA modded (all the bolt ons) "G" lost to him by 1 - 1 1/2 from what he tells me...
The guy then started talkn all this crap, so my friend generously volunteered me run against him... LOL....
From what I hear he is a young kid, just got the car, and only has the boost controller... unless he bought the car with mods already on it...
It will be video taped and on You tube / Streetfire...
Keep in mind, I also have a 5AT so I shoud not spin off the line to much at all because I do not TQ brake above 1500 rpms at launch because she bogs down if ya do...

yeah I was assuming he had a lot more going on with the car than just a boost controller with more boost. And if an NA G lost by only that much then you should obvously have the upper hand
Lately I've been going by roughly 8% instead of 10% for ballpark converting peak hp from dynodynamics to dynojet. I've noticed that most dynojets seem to dyno around 5-9% higher for the total torque curve depending on if it's STD or SAE correction
using hp = (tq x rpm)/5250, you can calculate the different hp numbers for different rpms
you can't add 8 or 10% or whatever to the total hp graph because that'd give a very false reading of hp at lower rpms. Where for instance it takes a roughly 26.25 tq at 2000 rpms to get 10 hp @ 2000 rpms, yet adding just 8 tq at 6500 rpms will get you 10 hp @ 6500 rpms
Really the tq curve is the most consistent where you can flat across just add 5% to everything.
The hp curve is going to vary though because it has to be recalculated for every rpm
it gets even more messed up when people are posting STD numbers instead of SAE

they installed a SAFCII fuel controller (ditched the emanage ultimate), MSD booster pump, HKS ignition amplifier, relocated the battery to the rear, AAM high flow cats since I burned up my crawfords by runnng stupid rich with my new AAM ECU vortech flash (not using the technosquare flash anymore), hotchkis under brace, lowering the stiffness of my front sway and some tuning.
Made 435whp when engine was cool. Otherwise was consistently making 415 and 375tq on their dyno when the engine was hot
I updated my big thread at the bottom (post 234) with all the details:
https://my350z.com/forum/showthread....179616&page=12
I have some handling stuff going in at the end of the month (suspension bushings, solid differential bushings, camber/traction rods, seats, end links, etc) so it's kinda just been living there lately

435 on their dyno???
Damn thats Frickn GREAT man!! Congrats.... Are you still running the SSV?
You running the 2.87 pulley? What size NAPA belt works with the 2.87?
You upgrade the blower yet? Do you have any internal work done or are you stock?
Wow.....

thanks, yeah it's the stock bottom end and still on the SSV on 96 octane gas. Still on the 2.87 pulley and the same size belt as I've always run which is the same belt size as yours I think except Jon was telling me awhile back your brand belt (and you IM'd me the info back then - thanks) looked like a stronger/thicker belt
I'm pretty happy with the torque numbers despite still running the SSV I haven't seen many vortech setups running as much torque as me unless they were using the 2.62 pulley or T-trim blower. Jon was saying every dyno he's seen with the SSV seem to show the power being identical to the stock plenum except for there's a little bump of power increase at the very top by 3-5hp. So I'd tend to agree with everyone that the crawford or a spacer would net some more midrange power, but at this point I'm leaving it until something way better comes along like possibly that cosworth IM
