Does anyone know how this can be done? What products are out there? And what are people's personal experiences with the products? I want it faster!

 

While I agree that the car could use more torque , I think overall it's a very well balanced package.
385 HP out of a 4.6 motor is actually pretty good. 8 speed auto does a good job as well. Don't forget that most of us get 30 mpg on the highway.

 

No idea, but I know the best way with these modern cars is typically through an ECU "tune."

I know there's a big market for this through companies such as APR, but mainly for more "sporty" cars with blowers (e.g., turbos). Just be careful as these typically void your warranty. I know other manufacturers will flag a car that has been modified. No idea about Lexus.

 

From what I've read, the Lexus ECU hasn't been cracked yet or barely. I think HKS has a supercharger available for the low price of around $18k to $25k. Or you can sell the LS and buy an RC-F, GS-F or ISF.

The LS isn't meant to be a fast car. It has plenty of power. Would I like more? Of course who wouldn't, but it isn't happening cheaply. Also with those big 24" wheels you want to put on, I would think the weight wouldn't help much in the speed department.

 

Perhaps adding more power would offset and regain some lost power due to the heavier wheels?

 

HA!
And lets no even talk about the additional strain that will be placed on the suspension, specifically-the front end which is already carrying the weight of the hefty V8.
When speaking about adding additional weight and speed/torque values, the suspension must be modified as well.

 

He already has this covered. He's adding 24's all around, that should be strong enough right?

 

Headers are available for the 430 that give you about 20 HP. Not for the 460 that I have seen. As mentioned, no tuning Lexus without an aftermarket engine management system. It's too bad because if you were able to tune for high octane fuel with a nice big intake and headers / cat-back exhaust I would not be surprised is this would equal 60 - 80 hp.

 

Lexus ECU has very recently been cracked and is being done for IS-F, RC-F and 2IS/3IS. Check the vendor subforums for those models for threads about them from a couple of CL vendors Looks promising.

Suspect they could do LS460 as well but probably after the other more performance oriented models are done (much larger market)

 

Not quite sure I follow you...
I was just saying that with the added size of the wheel (heavier wheel) and causing an unnatural indexing of the suspension, specifically the control arms/tie rods, THEN adding more power, im just assuming that with added front end weight + out of spec OEM suspension position + more force exerted on the front end from additional power (again-non OEM) will cause premature wear on the front end, if the suspension isn't beefed up to take the additional weight and force.

 

The only way to get significantly more torque is a supercharger. As noted there is one kit, from HKS, and it's in the $20k+ range.

We don't have a lot of bolt-ons for this car, and the ones out there tend to be expensive. It's a luxury car and not many owners are interested in modifying it for performance. An exhaust might get you a few ponies at the top end, but nothing you'll notice. You'll lose way more speed from putting on those 24s than you would gain from any performance mods currently available other than the HKS blower.

 

Agree...
Correcting the suspension/making the car corner a smidge better would be worth more than turning a 5.3 second 0 to 60 car into a 5.0 second one.

 

There was a similar thread some time ago. In my opinion the car is already too fast for its own good. The steering, brakes and suspension can't handle the speed this car can go. Although let me qualify I am talking about my 2007 model. The F Sport and other newer models may well be different.

I do understand if you want more torque so you can accelerate faster, that's fine. I have no quarrel with BEASTIN wanting that. As long as you are going in a straight line and don't have to make any kind of maneuver at high speed you're OK.

It just never ceases to amaze me when I see these minivans on the highway doing speeds above 80 mph and some are swerving in and out of lanes. Their center of gravity is so high, not to mention inadequate brakes, tires, and probably driver ability. Those people have no idea what's going to happen when they have to brake or take evasive action.

 

I was being sarcastic since he started a thread about how 22's are too small and he needed 24's so if he's going to redo the wheels he'll be doing the suspension and by the time he finishes all the mods he's well over six figures and should've bought a WRX on the side if he just wanted to have fun.

Personally you can't have it all. I have a friend with a Porsche GT3 and while it's bad *** sitting still and at SCCA is rides like ****! I can't imagine him saying hey I'm adding air suspension to soften this up. He bought a track car period and needs to take the good with the bad. Building an LS460 out with 24's and turning it into a hot rod makes no sense to me but he's free to do what he wants but the question is similar to saying, man I wish I could carry 4 adults in my Corvette. Find a limo company and stretch that chassis, can be done at a significant cost for sure. It can happen but is that what the best route to go is? I dunno....

 

Also the car has laminated glass and has gone through a ton of refinements to reduce sound penetrating the cabin. I wouldn't imagine adding an exhaust to defeat everything that makes an LS special.

Although I'll be the first to admit I'm curious how one would even stuff a supercharger in there given the already extremely tight quarters. Like I said before, I'm driving a car that has air suspension, dead quiet cabin, room for 2 adults up front and 2 Shaqs in the back yet still pulls a 13 second 1/4 mile with the A/C and street tires. Seriously we busted our *** to do that in a street car in the 80's!
