I took final delivery of my EB Z today, and have only driven it a grand total of 15 miles -- which isn't much -- but wanted to point out some of my observations.
Engine idles at 800 RPMs when fully warmed up (seems alittle high?). Idle seems very smooth, and engine noises are very minimal -- way more quiet than the 2001 coupe with LS1 that I previously had. Engine oil pressure seemed alot better on the new Z then on my 01 coupe when it was new. The old coupe haD ~18 psi at idle with hot oil, the new Z is ~32 psi
. Oil pressure at 2500 RPMs was ~30 on 01 coupe, where its ~45 to 50 on the new Z. These comparison numbers are both with factory PF44 filter (not the Ultragaurd, which will actually give even better oil pressure). Does anyone know if the oil pump in the LS6 is higher pressure/output as compared to the LS1s?
A note about this whole "does the engine hold 6.5 qts or 7 qts of oil" issue. I'll tell you right now, that these cars come with the oil level TO THE FULL MARKS ON THE DIPSTICK when they come off the train/transport truck. So, for all you die hard "put in 6.5 qts regaurdless of what the dipstick says" -- you are barking up the wrong tree on this issue!! The attitude should be that you always go by the dipsick marks (Mark S., are you seeing this?). If you don't believe me, ask your dealer PDI guy if he had to add any oil to make it read full on the dipstick.
I checked for trouble codes after driving it alittle bit. I did find code U1000 H (a history code, so probably a glitch). I reset it and checked it again after some miles -- did not reappear, so probably nothing to be concerned about.
The car drove absolutely great! The clutch and tranny operation was smooth as silk. No notchy sifting and no buzzing in the shifter. Also, no startoff noises from the drive train like some say happens and is 'normal'. The only bizzar sound I heard was the 'normal' can of marbles sound when turning off the engine with the tranny in neutral. If the engine is shut off in gear, this sound goes away. Anyone know exactly why this is??
The 1st to 4th gear shift feature (CAGS). I noticed that in order for the CAGS to operate, you must first have come to a COMPLETE stop. If you are still rolling, and shift into 1st gear, the tranny will shift into 2nd gear no matter what the engine RPMs are. I never realized this until dirving a stick. Also, if you start off from a dead stop, you will see the 1-->4 shift light come on, but it will go off at exactly 2500 RPMs or above, and not force a 1 to 4 shift. I tell you that for me the CAGS is a non-issue becasue I usually alway rev above 2500 in 1st gear when taking off from a dead stop -- hey, it's a Zee!
The exhaust note is absolutely perfect. I really don't know how GM was able to make it pass the required noise tests, but aparently it did. I don't think the noise standard counts any throttle above a constant low speed cruise, which the exhaust is fairly quiet at. But give it any throttle above ~1/4 and its hard to miss the sweet sound of the engine. I know for sure that I will not be buying any aftermarket exhaust for this car. IMO, anything louder under load would be too loud -- at least for me, and I do like hearing the exhaust .
Brakes -- one word ... WOAH!! ... and that wasn't even hardly putting any pressure on the pedal. I can tell that these binders are SERIOUS! No wonder every car mag has set new 60 to 0 stopping distances with the Zee -- and that was the 01. Maybe the 02 is even better in this department.
When behind the wheel and piloting this beast, you just get this sense of pure power and agility at your commnad. I can tell after just 15 miles that this is ONE AWESOME CAR!!
