Dissapointing power 04 G coupe

[Sentientbydesign]

I went to test drive an 04 G35 coupe AT at the dealership this weekend and I was really dissapointed.

My aging I30 seems to have better take off than that thing. So does my wife's 2000 Celica GT with a CAI and exhaust.

Do aftermarket intake and exhaust make a huge difference on the G coupe?

I know that sounds ignorant because I have them both on my I, but I don't have much first hand knowledge about the G.

I'm used to be pushed back into my seat, the G took a long time to rev up and seemed to start moving in the higher RMP range, but with very little torque.

not sure about the 04 coupe but i know the 05-06 sedan have more hp than the 04 sedan. i believe it's somewhat the same for the coupes. the 07 coupe, i believe, has 298 hp. the 04, i think, has 260 or 280.

not sure about your celica but i KNOW it's several hundred pounds lighter.

[zozoka1212]

Yeah, I am not sure about the 04 coupe(it supposely 5.6-5.8) but the Celica is well over 6 seconds 0-60. I think it is just your mind playing. Sometimes the car feels faster than what it is. Some others feels slower but they are not.

[SVTCOBRA]

pretty sure it's got 280HP. Yes, there are several things you can do to bump up the HP even more - spacer, z-tube, wai/cai, etc.....But, maybe you need to go and try another. Maybe something was wrong with the one you tried.

[G_whizz]

Did you drive it with the VDC off?

+11111 The VDC cuts out all of the fun stuff..

there is a lot more power there then you think.. the computer is just keeping you from using it.

Not even in the 5 seconds range with a 04 with a AT to add, considering the 07 g35S with the 306 HP engine does it a little under 6 seconds. True figures of a 04 AT 0-60 are more in the ranges of 6.5-7.0s

[Andy_V35Sky_350GT]

About 6 secs 0-100 for stock G's/350's.

Nissan figures were 6 seconds for AT 350's, 5.6 for 6 speed. Turn the VDC off, and remember, the G is a luxury coupe, you don't feel the pull like you do in say a riced up Celica or 200sx...

Turn vdc off or try another.

Hey Sentientbydesign,

When I first bought my 04 Coupe I felt the same way...the exhaust sounded awesome but just needed something extra from the engine. I added a few mods....the Stillen intake and Z-tube to start. Now it sounds and responses like a sports car should sound. Keep in mind it's not going to be vette fast, but put some money into it and you should be happy.

I drove a friends 350 Z with the 6 speed vs. my auto. It does feel much faster than you are really going...closer gear ratios maybe. See if you can find a G35 with a 6 speed and see what you think. I would also try driving another one maybe that one was just a lemon??

Not to fault the Mustangs here...I drove a early 90's model 5.0 Mustang LX home to detail. After getting it home...there is no way this car has a v8 in it...felt like the 4 banger and someone had put the 5.0 badge on. Checked under the hood and it had the 5.0 engine. To this day can't figure that one out....maybe you just got a bad G35 too....

[Sentientbydesign]

I'm definately going to try out two more of them. Another AT and a 6 speed.

Forgive the nescience, but what is VDC? I'm from the Max/I30 side and I don't ever recall seeing that acro.

I was just surprised to not feel pushed back in my seat. I thought I was going crazy, so I took my I30 for a quick run on the freeway like I did with the G and my I revs up and launches (though there's much to be desired once it hit's 5000RPMs).

Thank you all for the input. I'll update once I've gotten over to the dealer again.

[gday]

It's the weight of the coupe thats making the acceleration feel slow.. And as a matter of fact, yes it is slow. but once you pick up seed and weight is no longer holding it back, it should take off...

[audtatious]

VDC is pretty much TCS...Traction control. In the G, if you have VDC on and punch it, it will engage if it feels the wheels may start slipping. At that point, it applies the brakes to the rear wheels.

[G_whizz]

Ahhh... it's a lil button that will prolly be beside the trunk release button (not 100% sure on an 04) to the left of the steering wheel.

You will want to turn it off for full potential. Also, keep in mind that these cars shine in the high RPM... they LOOOOVE to be rev'd

Shift at 6700-7000 RPM's

[TheTick]

The right intake, plenum spacer and exhaust seem to be the best bang for the buck. Keep in mind that you're looking at less than 20hp to the rear wheels from these mods which will knock about .1-.2 seconds off your 1/4 mile time.

I think its a little more the just traction control. Below is a VDC on run vs a VDC off run!



The 12 second car is a scary scary fast Mitsubishi EVO with an ENORMOUS turbo. As the night went on I witnessed a 12.1 from the same car. The guy had a crowd everytime he pitted to make adjustments. But the car came and left on a trailer.

Not even in the 5 seconds range with a 04 with a AT to add, considering the 07 g35S with the 306 HP engine does it a little under 6 seconds. True figures of a 04 AT 0-60 are more in the ranges of 6.5-7.0s

Where in the world did you get the 07 times from??

0-60 in 5.3http://www.motortrend.com/road...sport/

0-60 in 5.2http://www.caranddriver.com/ro....html

I've stop watched my 07 Journey sedan in 5.0 flat with a passenger.

In the slip I posted about my 1/8th mile with traction issue in hot weather was a 9.125 at 78.801 find a racing calculator and plug that in and you'll get a 5.2 seconds to 60 estimate. Apply a SAE correction for weather its a 4.82 seconds to 60 mph.

I'll post a 13.7 second 1/4 mile slip in January. Even with the huge power loss from my only mod the fujita intake.

Had mine only a short time before I threw on my intake (non- Ztube... just a cheapie). Have also since replaced with a CX Racing cat-back.

Got to be honest though that I don't feel it is any quicker and, dare I think it, possibly slower??? I definitely think it likely has a little more top end but just off the line it seems to ever-so-slightly have more lag.

Could be simply a matter of me being used to the power now? Maybe a lack of back pressure is messing with the speed off the line?Would be a really fun experiement pulling out the stock intake and exhaust and reinstalling them just for comparrisons sake.

One thing that I think was an evident result though: according the the MPG/nav reading, the intake bumped this up by 1 mpg. That was a nice surprise though I don't know if this is "accruate and true" data.

[gwoods]

My advise is to search the infiniti dealers in your area a find a used 07 sedan?

07 sedan with 18k miles for $26k

http://www.autotrader.com/fyc/...light=

[Sentientbydesign]

So if the next test drive sucks, my only option is FI?

It's interesting that on the I30/Maxs we can pull 30whp out of our butts by swapping a y-pipe and doing CAI and catts.

But we move up to a performance car and we're trying to squeeze every last drop of NA power which equates to 20HP at a cost of well over a grand?

I guess Infiniti did a good job of designing for peak performance.

Exactly... nothing left on the table. did you see my post above your probably looking at low $20's for an 04 coupe why not buy a faster 07 sedan for $26?

Jeff

[gwoods]

Here you go 07 coupe for $24k

Just sign a power of attorney for me and I'll find you a car LOL

It is very possible for you to have lost some low end power and gain some top end. This happens alot when you go to a more free flow system. I bet you are a tad slower from 0-60, but a bit faster from 60-120.

I don't see what you're trying to get at? i stated that the times were a little under 6 seconds 07G35 which is exactly what you posted? did you read my post? And you stopped watched yourself for a 0-60? what kind of joke is that with obvious human error .You also fail to consider high elevation locations such as where i live in calagary, which also mean loss in power due to lower oxygen.""I've stop watched my 07 Journey sedan in 5.0 flat with a passenger"" Wow you should be able to destory a G37S easy with your "stopped watched 5.0", considering the g37 is sub 5 second range, and you with a passenger!.

My point is there is a big difference between a little under 6 seconds and a little over 5 seconds.

I'm not trying to argue with you I just am pointing out that the 306 hp 07 is quite a bit quicker to 60 then just under 6 seconds. At least everywhere but Calgary

You can convert your times using an SAE formula for elevation if you wanted to compare your Calgary times to somewhere with a lower altitude or air density. Here in the states Louisiana parts of Florida and South East Texas have great air density and post almost unbelievably quick times. Here’s a link to the site I like to use to compare my July 120+ degree times to my January 50 degree times http://www.csgnetwork.com/relhumhpcalc.html

I agree with you that racing in a parking lot with a passenger running a stop watch is by no means scientific but I got 5 seconds flat 4 times in a row. My track times convert to 0-60 in 5.2 seconds and its still pretty hot here in Phoenix. Just yesterday it was 94 degrees Fahrenheit at lunch. I convert my track time for air density and I get a 13.7 at 101.5 which will be 0-60 in less then 5 seconds.

Sorry if I came off sounding like a d!ck

I don't know if your being sarcastic or not but yeah I think I can beat a G37 with my G35 sedan.

I have a race scheduled with a G37 on the Saturday night after Thanksgiving. It will be at the track so win or lose I'll have time slips and video to post.

Car and Driver / Motor Trend only got 0-60 in 5.4 seconds out of the G37S they road tested.

The Sedan is 3497-3557 lbs depending on options and the G37 is 3700 lbs. The extra 24 horse power isn't available until pretty late in the powerband so I don't know. Its going to be a drivers race. I'll probably red light and the G37 will win

[Sentientbydesign]

I can get an 04 with around 65k for under $18k out the door.

We just bought my wife a 2000 Celica and we can't afford that payment plus another $500/mo for the 07 G35.

WHOA WHOA WHOA!

First of all this is a sedan, I was hoping for a coupe, but I didn't specify so no big deal.

But go look at the seller's comments...

"This vehicle has a 4.5L V8 engine and an automatic transmission"

They now make G45s???

[gwoods]

Yeah I saw that too. AND its at an Infiniti dealer

You know that they have the intern write the autotrader ads. Is that dealership close to you though? I'd go drive an 07.

How did the test drives go last night?

Jeff

[Sentientbydesign]

Didn't get the chance to go there last night.

My wife is sick and I went home to take care of her. That and my I needed an oil change. I work 7 days a week, so finding time is impossible.

You guys should have seen me without my jack driving onto the curb to gain access to the oil pan with my car half way in the street. Very NICO! lol

[gwoods]

Hope your wife gets better!

Is there another way to do an oil change?

Try to drive an 07 you'll love it. I was test driving 2002 Porsche 911's before I bought the G and the 07 G was faster!

There are no parts of the car I don't like.

Payments are all in the terms if you go through a credit union you should be able to finance it out. 18k for a 04 with 65k miles is pretty good. I've seen a few 06's going for mid-low $20's out here in Phoenix if its worth the drive for you. http://www.autotrader.com/fyc/...=true
