I do not understand what your are trying to say. You know both 2006 models are rated using the same method - the difference between the two engines is 14 HP. 14 is not 30. What does the old method have to do with anything? The question is - how much of the 14 HP is because of the larger displacement (3.2 VS 3.0) and how much is due the higher compression ratio (reason premium is required) I have no way of knowing - but part of the 14 HP must be because of the larger displacement - Like I posted before - if you gave TL buyers a chance to re program the 3.2 L to run on regular gas by flipping a switch on the dash and the result would be the loss of 7 HP (1/2 the difference - just a stab in the dark) I would bet many TL's would have their gas tanks full of regular unleaded - really - I bet many do anyway. Acura's use of premium is more marketing than performance - I bought the TL over the Accord because I like it better for many reasons - I use premium because that is what the car was designed to use - |

Replying to: ggesq (Dec 28, 2006 9:49 am) I'll take your side on that bet, as well. On the other hand, even if it did show that on an overly generous dyno, it would be almost impossible to tell with ones own buttmeter. I have to carefully control my clutch outtake in my 2004 TL 6-speed so as not to spin the wheels and induce wheel hop and torque steer. And that's with the "restated" 258 hp / 238 ft lb. base engine. Adding more horsepower to a FWD platform definitely runs into the law of diminishing returns.

Replying to: jdelabre (Dec 28, 2006 11:06 am) I'm sure you can do the math. It equates to about 230 WHP (wheel hp).

| Reading through the TL-S brochure, I see that premium fuel is required. That's 20 cents per gallon more than regular gas in my area. Has anyone exsperienced ill effects from running their 2007 3.5 TL-S on regular? What's the worst that can happen? | |

Replying to: dave911 (Dec 26, 2006 5:45 pm) Decreased mpg and decreased performance. Long term, possible engine damage? Quick math: 15 gallons fuel/week  +20cents/gallon x 52 weeks = extra $156/year. Is it worth the risk for $156/yr. on a ~$38,000 car? Not to mention the decrease in mpg which will likely offset the "savings" directly at the pump. I hate paying for premium, but for the above reasons, I do and have kinda gotten used to it for my '05 TL. Penny-wise and Pound Foolish I won't be! |
