As do I... but.... even with a lease, you are supposed to have a minimum of tread remaining at turn-in time, or you have to replace the tires or pay for replacements...so... not being able to rotate them could wear out the drive wheel tires prematurely...

That said... I think my GTO's tires were under the limit, and I was not charged... pays to have a good relationship with your dealer.

 

Yup...I have been interested in a lease...but the fact it is not titled in your name scares me. If you decide after the lease is up that you wanna buy the car, you have to retitle it and pay taxes on it. Least with Smart Buy, you already have the car in your name if you wanna keep it

 

The GXP has a similar weight and power output as my GS400 did, but is FWD and short one gear.

I ran a 14.7@97 in mine... best times I ever heard of for a stock GS4 was 13.9 @ 101.

I guess I just can't see how with such similar power and weight numbers the 'average' person in a GXP runs a 13.8 and they run as well as 13.6...

 

There are several people on www.clubgp.com getting in the 13's stock.

 

Can you really compare two different cars like that without dyno'ing both? because the few GXP's currently dynoed stock, have pulled better numbers than 303hp GM says they have(i'm not suprised).
The best time ive known of is a terrible traction 13.67 @102+...(2.2+ 60ft i think)
And the short one gear coment?...The fastest GXP's currently are finishing the 1/4th in 2nd gear. (2.97gears). Using the tapshift to hold 2nd gear through the end. The ones shifting into third are coming up slower.
I'de say the biggest problem is traction. Most of the best runs have 2.2 somethin 60ft times.

If you line up and hammer the gas, it goes no where...you have to take some time to learn how to launch your car correctly. Just like with any fwd car that has decent power.
Dont get me wrong, i'm not the spokesperson for the GXP or anything. Just think GM should have did the v8 thing in the W-body long before 2005. They flirted with it in early 90's with first gen lumina, and again with an LS1 on the 00-01 impala, but were destroying trany's over and over.

 

Any way to bypass the speed limiters?

What top speeds are you getting from non-limited GXPs?

 

I am not sure the GXP is speed limited. The Comp G was not and had a top speed of 147mph. I could see the GXP hitting 155-165.

 

I wonder if torque managment has been revised across the board in '06?
I drove a '06 Grand Prix GT with 3.8L S/C back in the fall at Indy, it felt a lot faster to me. The Series III 3.8 actually sounded like it had some soul. Kick downs at 20-30 mph I thought were really impressive. I could feel all 260hp, which was a complaint when the Series III debuted because they didn't feel any faster than the previous gen GP, and were only a tick faster because of torque managment.

 

I suspect fewer drivetrain loses in FWD vs. RWD. and the LS4 probably has a flater torque curve than the multicammer toyota V8

 

With the new trans , which is a heavier duty version of the 4T65-e , they were in fact able to scale back the tq management . So it would stand to reason the 06 GT's with the 3.8 SC engine would feel faster than the 04-05 GTP's .

Man , the GP aftermarket is so popular and there are so many sub 12 second GTP's already .....it will take no time at all for the GXP's , LS4 Impala SS's and Montes to just get dumb stupid fast . These guys are as hardcore as the F-body crowd

 

It makes me chuckle, how folks are tip-toeing around the 05-06 GTO. Since when did it become fair to compare the 05-06 GXP to the 04 GTO? The 05-06 Goats have 400HP and 400TQ... RWD... and even with a little more curb weight than the new GXP, that's plenty enough to lay down the smack on one. In warm weather driving... there's not much of a contest really. The GTO would win in just about any scenario, strip or track. Now winter... that's a little different. That's one reason why I picked up a used CompG. But if I compared my 04 CompG to my 05 GTO (and of course I have)... well that would be cruel

Well I disagree with pretty much your whole list. I like the GXP interior... but also the regular 04 Prix's. The seats? AMAZING, and TONS better than those on my 97 GTP (I commonly used to slide around on the 97's seats on freeway ramps ). Dash & console plastic? Hmm. I don't spend a lot of time feeling up my dash and steering wheel airbag cover ...and this rubbish about the dash cover being too 'rubbery'.... come on, what else would you suggest, painted steel like on the 1956 Bel Air?

The interior on my CompG is a vast improvement over the previous Prix. I love the upgraded HUD... the RDS stereo... the THREE folding seats... and the advanced integration between HUD and other systems. It just WORKS... and is a great design IMHO.

 

According to Roger Sears, it depends on the conditions of the motor at the time, especially temperature. If it is running on the hot side, the engine will limit the top speed to 143. If it is running cool enough it can stretch it out a little more.

A way to bypass it would be to let Chris White do one of his tunes to the LS4. He's been getting some pretty good power gains as well.

 

Car & Driver reported a limited top speed of 143 mph on there road test

 

That's what facinates me about the GP, especially the blown ones.

The aftermarket on these cars seem even bigger than the 4th gen F-bodies were.... and more affordable.

 

Yea, their are several dedictated vendors out their for the GP market and some of those cars are making tons of power. However, nobody has officially stepped up yet for the GXP/SS lineup. But, i'm sure their are things in the works. I think a lot of people are still worried about the whole DOD thing.
Weak link has always been the tranny. GM just hasnt been able to make a FWD tranny that will hold the hp/tq to mod. Although, maybe the one in the GXP will hold up better.
