I was having a discussion with my buddy about various cars and there specs. He asked me, so what does my GS run in the 1/4 mile? I had to think about it for a sec.... I honestly didn't have a clue what our cars run. I looked real quick on the phone, not much out there for a 07-11 GS350 1/4 mile times. Would any of you guys know? With its HP and torque figure i would assume a high 13 sec or low 14? Am i even close or way off?

I'd be surprised to see a gs run a high 14

Thanks you Ibidu1.

I noticed that was for a AWD, any specs for a RWD 350? I searched and I can't find anything on our vehicles.

Take your car to the track just to make sure

High 14s? It definitely surpasses it (except the 300's, and even worse, the 300 AWD models).

13.8? Iunno, maybe from a launch, it has the AWD advantage, but that's all I see. From a stop, a 450h > 430 > 350, all RWD respectively.

I know because I've raced both cars.. Haven't had the priviledge to race a 460 though, so I can't say much .

Let me tell you, the 450h just GLIDES past me from start to finish like I didn't matter...... I'd be surprised if the 350 broke 14 even.

I believe there was someone running a 450h on this very forum at the track, and he only managed to get 13.8 out of that....

Hope the above gave you a bit more insight.

Can't agree with you more here GS-F, a track night's what.... $15 nowadays? Shouldn't be too much, and every location and it's atmosphere predicts how YOUR car runs .

I will be hitting up the quarter mile this sunday and I will be racing my buddy in his 335i unless he backs out. I will most def be recoding it and I'll post the video up.

13.7 here i come :P

Make sure you come with a charged battery! Otherwise you'll lose quite a bit of performance!! Remember, I'm not sure if it was 13.8, it was only a guestimate.... the 07 450h definitely ate my v8 alive...... EASILY! (he even gave me a 1-2 car length headstart too afterwards)

It should be fine since it's like an hour away, but I will try to conserve as much of it as I can.

Anything else I should do? I was thinking of cleaning the throttle body, new air filter and maybe spark plugs. Im sure it will be negligible, but I would like to be as well prepared as I can be.

Nitrous lol

Whats so funny?


I ran a 14.0 at 102mph on bald winter tires in my 08 gs460. I have have a progressive nitrous kit assembled for the car already, will install it come next spring.

That sounds great! Before your run, about a tank before, run gas cleaner. If you're also feeling dicey, near the end of the tank You can drop in Race gas..... About a few gallons should do since the track is about an hr away lol. That should hopefully give you a good edge on performance.

Just don't leave that gas hanging in there too long (dilute it with normal gas after your race) as it will corrode and eat your gas lines if you leave it in.

Make sure after every few runs you reset the ECU, so that it doesn't LEARN and starts leaning out your car while you're purging LOL!

A few members here have had really bad lucky in related applications, but they're more towards FI.

Thanks guys for all chiming in. So basically a 14.0-14.1 1/4 mile is expected out of a 350, 13.8-13.9 for the awd 350 and V8 counterparts.

If one would put stickier tires and had a healthy launch out the hole, its possible for a 350 to dip into the high 13 mark, key word possible.

I would take mine to the track , but all I have around me is a 1/8 mile.

I feel confident that I could run 13.5 or lower range.. HEADERS make a huge difference for our cars..

Purging sprays nitrous out into the air so im not sure what your getting at there. But I have a separate fuel souce and injector for fueling. I also have an AEM standalone and a fields piggy back i may use.
