In my experience,I have found that that even a reasonably experienced Vette owner will have at least a 2+ 10th slower E.T. Than what MFGer,and some of the Car Magazines test results show. It is a Super Fast Car though. I'm sure they even fudged on the HP like the Challenger SRT's 707hp Claim. The Vette's Torque Figure alone calculates more like 675+ HP. Just your typical Grocery Getter HP Car of Today !  |  IP: Logged Richard Hamilton Phenomenal Film Handler Posts: 1341 From: Evansville, Indiana Registered: Jan 2000 posted 10-27-2014 08:10 AM                     o.k. so I freaked out all my friends, family, neighbors, loved ones...... I traded in my corvette a couple weeks ago for a 2010 cadillac CTS (black on black, i tinted the windows, sweet car). Today i'm going to look at a 2008 corvette that was just traded in on sat. Black on black...maybe pictures to come?

Everything is approved. Now they are detailing it and going over every thing. I haven't test drove it yet, but my buddy said it should be a good car, clean history and the guy traded it in for a newer Vette. The only bitch is my insurance goes up .90 cents a month. . Budget wise I'm towards the top of my comfort zone. Hopefully I'll keep this one  |  IP: Logged Steve Matz Jedi Master Film Handler Posts: 672 From: Billings, Montana, USA Registered: Sep 2003 posted 10-27-2014 02:24 PM                     Richard; If your going to keep this one;go buy a 2015 LT4 Crate Engine when available. Not only will you have a close to 700hp Tire Shredder;but with the 4 cylinder deactivation feature you can still get 26mpg....The Best of Both Worlds 2015 ZO6 LT4 Corvette Engine-650hp (actually closer to 700hp)  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 10-28-2014 12:13 AM                     At least the ALT still will be easy to remove when it gets cooked - not buried down by the compressor where you gotta yank out the radiator to get to it. And this motor is naturally aspirated? When they deactivate the four jugs, do the valves hang open to kill the vacuum, or just the injectors shut down and you got four jugs becoming air compressors? -Monte  |  IP: Logged Steve Matz Jedi Master Film Handler Posts: 672 From: Billings, Montana, USA Registered: Sep 2003 posted 10-28-2014 02:28 PM                     OK MONTE;Here Goes Cylinder Deactivation (Active Fuel Management) To provide maximum fuel economy under light load driving conditions, the engine control module (ECM) will command the cylinder deactivation system ON to deactivate engine cylinders 1 and 7 on the left bank, and cylinders 4 and 6 on the right bank, switching to a V4 mode. The engine will operate on 8 cylinders, or V8 mode, during engine starting, engine idling, and medium to heavy throttle applications. When commanded ON, the ECM will determine what cylinder is firing, and begin deactivation on the next closest deactivated cylinder in firing order sequence. The Gen IV engine has a firing order of 1-8-7-2-6-5-4-3. If cylinder number 1 is on its combustion event when cylinder deactivation is commanded ON, the next cylinder in the firing order sequence that can be deactivated is cylinder number 7. If cylinder number 5 is on its combustion event when cylinder deactivation is commanded ON, then the next cylinder in the firing order sequence that can be deactivated is cylinder number 4. Cylinder deactivation is accomplished by not allowing the intake and exhaust valves to open on the selected cylinders by using special valve lifters. The deactivation lifters contain spring loaded locking pins that connect the internal pin housing of the lifter to the outer housing. The pin housing contains the lifter plunger and pushrod seat which interfaces with the pushrod. The outer housing contacts the camshaft lobe through a roller. During V8 mode, the locking pins are pushed outward by spring force, locking the pin housing and outer housing together causing the lifter to function as a normal lifter. When V4 mode is commanded ON, the locking pins are pushed inward with engine oil pressure directed from the valve lifter oil manifold (VLOM) assembly solenoids. When the lifter pin housing is unlocked from the outer housing, the internal pin housing will remain stationary, while the outer housing will move with the profile of the camshaft lobe, which results in the valve remaining closed. One VLOM solenoid controls both the intake and exhaust valves for each deactivating cylinder. There are 2 distinct oil passages going to each cylinder deactivation lifter bore, one for the hydraulic lash-adjusting feature of the lifter, and one for controlling the locking pins used for cylinder deactivation. Although both intake and exhaust valve lifters are controlled by the same solenoid in the VLOM, the intake and exhaust valves do not become deactivated at the same time. Cylinder deactivation is timed so that the cylinder is on an intake event. During an intake event, the intake cam lobe is pushing the valve lifter upwards to open the intake valve against the force of the valve spring. The force exerted by the valve spring is acting on the side of the lifter locking pins, preventing them from moving until the intake valve has closed. When the intake valve lifter reaches the base circle of the camshaft lobe, the valve spring force is reduced, allowing the locking pins to move, deactivating the intake valve. However, when cylinder deactivation is commanded ON, the exhaust valve for the deactivated cylinder is in the closed position, allowing the locking pins on the valve lifter to move immediately, and deactivate the exhaust valve. By deactivating the exhaust valve first, this allows the capture of a burnt air/fuel charge or exhaust gas charge in the combustion chamber. The capture of exhaust gases in the combustion chamber will contribute to a reduction in oil consumption, noise and vibration levels, and exhaust emissions when operating in V4 mode. During the transition from V8 to V4 mode, the fuel injectors will be turned OFF on the deactivated cylinders. The ignition system secondary voltage or spark is still present across the spark plug electrodes on the deactivated cylinders. If all enabling conditions are met and maintained for cylinder deactivation operation, the ECM calibrations will limit cylinder deactivation to a cycle time of 10 minutes in V4 mode, and then return to V8 mode for 1 minute. Switching between V8 and V4 mode is accomplished in less than 250 milliseconds, making the transitions seamless and transparent to the vehicle operator. The 250 milliseconds includes the time for the ECM to sequence the transitions, the response time for the VLOM solenoids to energize, and the time for the valve lifters to deactivate, all within 2 revolutions of the engine crankshaft...  |  IP: Logged Buck Wilson Jedi Master Film Handler Posts: 894 From: St. Joseph MO, USA Registered: Sep 2010 posted 10-28-2014 04:35 PM                     The engine pictured is supercharged  |  IP: Logged Steve Matz Jedi Master Film Handler Posts: 672 From: Billings, Montana, USA Registered: Sep 2003 posted 10-28-2014 05:34 PM                     The Supercharger on this new LT4 Engine is Actually Smaller(CFM wise) than the one used on the 638HP LS9 Engine but it's efficiency along with Direct Combustion Chamber Fuel Injection has enabled it to produce a good 25+hp more than previous LS9 Engine...  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 10-29-2014 01:26 AM                     That Deactivation sequence listed above reminds me when GM did it with their Cadillac 6-8-4 setup on that 368ci V-8 back in 1981. Also, with the sparkplugs still firing, looks like this is using the "Waste Spark" system were two plugs are firing at the same time, but 180* out of phase with each other with one plug firing electrode to terminal and the other is firing terminal to electrode - meaning one coil firing both plugs. Thx for the post though. -Monte  |  IP: Logged Richard Hamilton Phenomenal Film Handler Posts: 1341 From: Evansville, Indiana Registered: Jan 2000 posted 10-30-2014 09:27 AM                     So after some minor confusion on the year of the car, i got it the other day. Before I went to look at it, I called and just asked some salesman what year it was. I heard him ask some one else and he said 08. It's actually an 05. It's weird, my insurance actually went up 7 dollars a month for the older model. After driving for a day, I found out the OnStar won't connect, but the best surprise so far is a little switch on the side of the center console I stumbled upon. Being adventurous, I had to switch it. My car went from a mild regular sounding daily driver to a throaty muscle car. Dual exhaust mode! Aftermarket and I haven't checked it out yet.  |  IP: Logged Steve Matz Jedi Master Film Handler Posts: 672 From: Billings, Montana, USA Registered: Sep 2003 posted 10-30-2014 01:04 PM                     Nice Throaty Exhaust http://www.superchevy.com/how-to/vemp-0710-c6-corvette-exhaust-install/  |  IP: Logged Buck Wilson Jedi Master Film Handler Posts: 894 From: St. Joseph MO, USA Registered: Sep 2010 posted 10-30-2014 04:58 PM                     Richard, OnStar went from analog to digital a while back, bricking all devices prior to I believe 2007? 2006? I know 2005 is analog for sure though.  |  IP: Logged Richard Hamilton Phenomenal Film Handler Posts: 1341 From: Evansville, Indiana Registered: Jan 2000 posted 11-04-2014 12:00 PM                     o.k. time for some pics. The CTS. Very nice car. Front of the new Vette! Side shot. And last, what I suspect people see when I pass them!! The sun was shining just right for that last pic. After driving it for a week, I have to say it is by far my favorite.  |  IP: Logged
