hi guys I took my new to me 2006 gs450h to the track last night and got a 14.5 on the 1/4 not bad only had the car for 3 weeks can not for the life of my work out how to launch it lol got my 60" down to 2.1 . I had half a tank of fuel so that won't help lol .here's a video of the tyre warm up
Hi first time in a forum but i read some slips and threads someone ran consistent 13.9s. I just did my first timed events this week and I could only get 14.4 as my lowest time with mine. I would love to know what mods i can do to bring my time down, I saw videos of gs450h's doing mid 13s and 13 flat i would like to achieve that any advice or information would be helpful.
1) Check your final drive. USDM & JDM cars come with 3.769, the rest come with 3.266. The 0-100kph times (no 2ft dragy roll out) drop from like 6.3 to 5.8 with the 3.769 diff, at least in my case (EUDM car swapped to USDM diff). This is with EU 95(RON) gas and a winter 225/50/17 set (oem gs300 10spoke or whatever wheels), 0.5 slope or something, dragy.
2) Tyre pressures, weight in trunk, weight in fuel tank, traction control (just the button that turns it sorta off until 60-ish kph, shouldn't even need that and you don't want to spin out anyways), good tires, basically the standard drag race optimizing stuff noted in the first post. The car shouldn't really need more than 3 bars for a 1/4 mile run, assuming that the battery is in decent condition (i.e. doesn't go down to a single bar by the end). You can still get it to 6 bars by force charging.

a drag pack in the rear and 500 lbs of weight reduction should be enough for a 13 flat in a 450h. not much you can do other than that, no way to make more power...
I honestly haven't seen a verified 13 flat in a GSh anywhere. And there are technically ways to make more power while staying hybrid, but nobody's explored them. The transmission and resp. motors can handle the ls600h's engine, the inverter appears to be overbuilt (camry IGBT module apparently works). So, technically, if you can fool the hybrid ECU to let more power come out of the engine (this car pretty much has a built-in dyno) without panic closing the throttle (see the prius... gen1 or 2 blower and then turbo project, worked until the ECU started limiting things)...
Anyways, not really the point of the car in the first place. Main thing is the diff if for some reason you have a non-USDM/JDM car (RHD does not necessarily mean JDM).

That's what I meant, if no one's done it, it doesn't exist in my eyes, but maybe soon someone will figure that out soon.
The diff is definitely important, I imagine the 4.08 from the 2IS350 would be an even better upgrade, along with an LSD and drag pack to really take advantage of the low end power.
