Very interesting..... article says that the motor is filled with Mobil 1 Synthetic Oilhttp://www.automobilemag.com/features/news/0609_2007_saturn_sky_red_line_dyno/
228 WHP and 248 lb-ft of torque
Not necessarily.The dyno graph from Automobile states WHEEL horsepower not crank which is what cars manufacturers use.
No, the new SAE ratings required the way crank HP be calculated is more realistic to final production. Like they can't remove all the accessories and modify parts. It's still just the crank value and not the wheel value.It will be filled with Synthetic from the plant. Exactly the same way that the ION Redline had Mobil 1 Synthetic straight from the plant.
Interesting to see that they've been quoting that 260HP number in all the advertisements though. I thought the new SAE law about HP ratings made it so they had to quote WHP, not crank. I dunno, maybe the rules are different for RWD than for FWD cars.
Woah....that's bad!!!!!I changed my oil SKYGAZR and it definately was not synthetic. But even the people at my dealer thought it was supposed to be mobile 1.
Not actually, GM is quoting an under rated crank value, the wheel value just happens to be very similar.Not necessarily.
With the ION Redline, all of Saturn's info says it is rated at 205 HP. A LOT of people actually dyno their ION Redlines in the 205-210 WHP range. So...for that, Saturn is quoting Wheel HP.
Actually it can, it's called a Crank Dyno. It's a device that the crankshaft of the engine is attached to and used to calculate the crankshaft values of the engine. Watching various TV shows on Speed and Spike you'll see them benchmark engines that way. The real issue was not that companies were guesstimating the value, they were not using engines that necessarily would be the final production engine you'd find in the car and they were using different formulas for various things. The new standard is stricter on what you can do and how it is done.Crank HP cannot be measured, it can only be estimated based on a measured Wheel HP. So, up till last year, the Japanese were 'artificial' boosting their HP numbers in the sales info by quoting Crank HP estimates instead of hard and fast Wheel HP measurements.
