Morning all,

Also wondering if there are any performance tweaks for the V6 Cayenne?
When I bought my 2005 two weeks ago it was unexciting, I assumed the Dealership (Lexus) had simply filled it with Regular Gas, so I am driving it like I stole it to use it all up.

I did put Fuel Injector Cleaner in the Tank too, and have noticed great improvement on acceleration from standstill, but Kick down for overtaking still "just makes it louder" without much increase in speed.

Had a Saab when I lived in the UK and the enhancements were a long list from simple to swapping most of the components.

Thanks in Advance.

Sell it and buy a turbo. Not to point out the obvious, but you bought a heavy SUV with the smallest, least powerful motor. It's not going to be particularly fast, no matter what you do to it. Either enjoy it for what it is, or sell it and buy a Turbo.

Thanks for the heads up. Assumed there may be a chip mod, a remap or perhaps a K&N Airfilter tip.

I know all cars made after 1998 are down tuned to keep the tree huggers and delicate of hearing from crying and a few simple tips can usually eak out a few more BHP and/or better MPG.

Edited to Add: My Saab 95 Low Pressure Turbo 2.0 was 95BHP and 38 mpg stock, after a remap the Turbo could spin freely, making 135BHP and 42 mpg.
Could have gone to 305 BHP but that meant new 3" manifold, De-CAT 3" Exhaust, Upgraded Clutch, brakes, suspension.

Yes BUT this isn't a turbo motor. There isn't a whole lot left on the table. You can spend your money on a tune and air filters and really only experience a lighter wallet. You won't be able to feel 10hp on a 5000lb truck.

But the correct RON rating fuel will help right, along with cleaner Fuel injectors?

Sales guy admitted they filled it from empty with Regular Gas.

It wouldn't hurt - but you will not be able to feel much difference, early year V6, like you got, weren't exciting

LOL. I literally clicked on this thread to type exactly the same thing.

Aislinns, you aren't going to be able to make enough of a difference for it to be worthwhile, better to get what you want. This is similar to those people that buy a $2500 civic, dump $5000 worth of parts in it and end up with a $2500 civic. Just get the right car in the first place.

A few years ago, I had a guy pull up next to my 968 at a red light. Full-on rice burner, had the coffee can mufflers, had the huge rear-wing that would be at home on a 747. He yelled "Want to race?" ok. "I've got $5000 in this motor!" ok. At the next light, once he caught up, he wanted to know if my car was a v8, no. Turbo? no. Just a stock 4-banger.

Get the right car in the first place, you will be much better off doing that than throwing good money after bad.

cheers,

Any modern normally aspirated engine has little chance of any significant gains.

Manufactures tune their engines for optimal performance and economy (emissions).

Third-party venders will beg to differ, but the truth is that the paltry 10 -15 HP gains you get are barely felt. You need at least 100 HP to make a significant difference in performance, then you need to also consider suspension and brake upgrades to manage it. Sometimes remapping the ECU results in better performance at certain RPM, but the long and short of it is that it's just not worth it.

Although some people here will scream at me, I will give you my opinion. That is, stick with the stock V6, as it is dependable and good enough to do the job (towing may be an exception). If high performance is something you want, buy a sports car. As good as the Cayenne is, it is not even close to a competent sports car as far as overall performance goes.

If you can't have two vehicles, the Turbo is a logical alternative. It will address some of the acceleration desires and the brakes/suspension are better tuned to the power.

I have an '05 V6. If you're looking to overtake, you bought the wrong vehicle. It's fast enough to get up the on ramp, but I wouldn't do anything speed-racery in it. Just relax and enjoy the ride. If you put high-octane fuel in it, the only thing that will go faster is your paycheck.

Marv

Our 2006 V6 is perfectly road worthy.

Do I wish I had more passing power from time to time? Yes, but it isn't necessary and the stock brakes already are a little wimpy anyway.

For overtaking you should put it into manual mode, downshift twice, get it up to speed, check that it's clear and then go for it. The secret is to get up to speed before you pull out. I cringe when I see people pull out and then speed up. Works in a fast car, but not in the family Honda Civic.

If your butt dyno is calibrated well enough to feel a difference after changing fuel and running injector cleaner through the car then you truly have a transcendent set of cheeks. We are talking very marginal amounts of HP, whether it be the mods or the fuel itself. With used prices being what they are, just get a turbo.

Shawn Stanford

^This.

Of course, why would anyone buy an SUV to go fast? That's what sports cars are for. Porsche sells those, I think.
