0-60 Times?
Hey guys. I've been searching around the forums and was curious what 0-60 times you guys are seeing. I know the gs400 isnt a drag car but i was wondering if it was possible to break 5's NA consistently. I know rock a lex posted a 4.76s but wasnt really consistant. Thanks for the input!

It's all about traction. I can hit 60mph in my car in the low 4 sec range if I'm on drag radials and that's with some light-moderate wheelspin. On full boost with my 305/30-19 Michelin PS2 street tires, my car spins the tires up till around 120mph. On street tires I actually accelerate faster from 0-120 if I drop the boost down to 20psi vs 30psi lol. At 20psi I spin and finally hook at around 70-80mph. At 30psi with street tires it's pretty much hopeless until after 120+ lol. With drag radials, the situation is much improved and I'm able to run full boost without too much of an issue. Keep in mind, my car is the 2JZ, not the V8.
For the V8, you have a ton of torque down low and that results in very heavy wheelspin if launched hard. Wheelspin is your enemy, if Rockalex put some drag radials on his car then he would have much more consistent times. Also another issue with his car is that I believe he's on the stock transmission(internals wise). The stock trans is hesitant and slow on the shifts. My trans has been race built and my shifts are about 1/10 of a second or so.

The GS has is heavy and it's quite a bit of mass to move around. Mine is especially heavy with the system in the trunk(250-300lbs), which I will be removing soon. The current car weight with no driver and a full tank of fuel is 4050lbs(weighed on highly accurate digital scale). I'm hoping to drop it down to a more reasonable 3600lbs after I do some weight reduction and removal of the system.
Yes, run drag radials. Of course it's not practical for the streets, but if you want every advantage you can get when racing at the track. You're racing at the track right?

Well, aside from getting drag radials you could get appropriately sized rear wheels and tires and run lower air pressure in them. This would/should be sufficient for a modded NA GS4XX.
In my situation where I have been doing my latest testing I have had my stock 225's on oem 16" wheels with about 40psi in them...lol for better gas mileage. However, not so good for traction purposes. I have yet to relieve pressure and re-do my testing to see if it helps any; I will do this soon.
What I really can't wait for is test with my 275's on 19" forged wheels; my spring/summer setup. It WILL make my times much better and more consistant but I did only get 275/30's...where I should have really bought 275/35's with the thicker sidewall...they are still very low profile and sporty but are a good amount thicker than my current 275's. I realized shortly after I bought them that they were a bit too thin to achieve great traction and running them with 40-42psi didn't help either.
My goal when I put them (275's) back on again come April is to run them at 35psi and do some more G-Tech testing...I BET I will run low 5's 0-60mph consistantly - no problem. If I am still getting excessive wheelspin I will look to buy a set of rear 275/35's. Then my two (practically brand new) 275/30 rears will be up for sale shortly thereafter.

Rock, Do you have any mods you plan to do in the future besides these tires. If they count as a mod...

You, and you alone, make me want to sell my GS400 and get a GS300. Of course I would then need a budget and the know how to do a bunch of modding.

However, the above needs to be addressed ONLY if your CURRENT setup is failing you in the traction department...such as in my case.

Rock-a-lex is right. Tires are the most important mod on the car. Who care how good your suspension or how much power your engine has. What's the point of all that if you have crappy cheap tires on? You will only get about 75% of full potential if you have crap tires on. It's the thing that hold to your car to the road, so make sure you don't skimp!
