What All Specifications Does That Need To Best?

What All Specifications Does That Need To Best?





Elon stated that the Tesla truck will meet or exceed the Ford F-150 in specifications, but also the Porsche 911 at the shareholder meeting. What all specifications does that need to best? My F250 diesel has 800ft-lbs of torque, double what my last F150 Ecoboost had. Both accelerate more-quickly than what I need from a truck when I have cargo. I upgraded because I haul two snowmobiles up on the sled deck I have that sits in the bed, so the F150 is not quite there. You can easily overload an F150 and it becomes pretty unstable. I would like to see a 3/4 ton SRW that has sensors capable of telling me if I am unevenly loaded or overloaded, etc and can provide a nice ride when not loaded. 8k upgrade for Ford. There are a lot of truck owners who are already used to paying 60-70k for a truck, but can't take the compromises that come with a quarter ton pickup.

The earlier generation 996 and Boxster had a pretty serious failure rate with the IMS bearing. All 2005 launch year 997.1s, including both the 3.6 M96/05 and 3.8 M97/01, use the same small bearing from the 996 and MUST BE REPLACED. 10% discount over newer models. However many pros will tell you they prefer the 2005 for the serviceability of the IMS. You need to remove the transmission to replace the IMS so most people club it with the clutch job. 2500 at an indy. All 2006-2008 model year 997.1's, including both the 3.6L M96/05 and 3.8L M97/01, use the new "large bearing" IMS which effectively solved the problem. These can't be replaced and don't need to be. The failure rate is negligible. Some 2005 model years also have the large bearing which you can estimate by checking your engine number. But Jake Raby has pointed out this isn't exact so the only guaranteed way to confirm wether you have a large or small bearing in a 2005 model year is by visual inspection, which means taking off the transmission.





How to check your engine number? There are three different serial number types for the three engine variants in M96/M97 cars - base model M96.05 3.6L engines, S-model M97.01 3.8L engines, and the X51 power kit M97.01S 3.8L engines. All three have slightly different engine serial number formats. For S-model non-X51 M97.01 engines the serial number is of the format M97/0168YXXXXX. So the first two digits are 68, followed by the year digit, followed by a five digit serial number. But the full serial is M97/0168YXXXXX. 3.6L base engines have a similar format M96/0569YXXXXX (not positive on the 05, can someone check?). With replacement engines there is an 'AT' in front of the final eight digits. So a S-model 3.8L factory replacement engine the format would look like M97/01AT68YXXXXX. Bore scoring is rare but it can happen to all 997.1 model years. It's now even cropped up in the 9A1 motors in a few 997.2 and 991.1s. The issue has largely been isolated to cold weather cars from the midwest and Canada.





On this forum we've only heard of one warm weather 997.1 its ever happened to. Armed with the Carfax history, a proper PPI and good information you should be able to mitigate your risks. There are actually two different issues that are being lumped under the Bore Scoring umbrella - one is actually bore scoring and the other is bore seizing. Both of these are becoming better understood but still seem to be caused by not any one thing, but when a few things align and happen at the same time. Bore scoring happens when the piston rocks in the cylinder and then scores or scratches the cylinder walls but sometimes doesn't really damage the piston. Bore seizing occurs when the piston becomes larger than the cylinder bore and essentially gets stuck or bound inside of it, which then scores or scratches the cylinder walls and the piston. It's a small distinction and doesn't really matter either way, because once the cylinder walls are scored, the score lines provide an avenue for oil to sneak past the piston rings and for compression to leak out of the cylinder.
