2006 TL horsepower!!

[jadkar]

I'm sorry if this is a repost, I did a quick search but didn't find anything.

I was just looking at Acura's website and I saw that they are advertising that the TL has 258hp!! Is that correct?? My 2004 TL was advertised as having 270hp. Is this s screw up, or did they over-rate the engine before??

[AcidLotus]

Neither. Honda and Acura now rate all their models with the SAE horsepower measurements. Therefore, just because 258 is lower than 270, doesn't mean that it's any less powerful, it just means that 258 is a more accurate number of what the HP is standardized at, but realistically it's probably closer to 270 at the flywheel.

SAE = more accurate.

[kommon_sense]

test procedures also changed requiring manufacturers to include losses due to power steering in the advertised hp numbers.

I will own this car one day

Same engine, same power as before as well. Standards for testing changed so it is represented by a different number.

Its rated lower now but im still beating on new maximas with my TL so it doesnt make a difference.

i have a ques?? does a new tl like the 04 or 05 handle like a boat or does it handle good ??

I have an 05 and my car handles really well and i have the regular suspension not the a-spec. The a-spec suspension gives it better handling but the stock works fine for me at low and high speeds.

You know the TL only makes 212WHP. I think honda/Acura are overrating there engines. S2000 makes 190WHP and they claim 240HP.

The factory rates it at crank hp not wheel hp. There will obviously be drivetrain loss of hp especially in a rear drive car like the s2000.

Usually there is a 15-20% loss in the drivetrain. 212WHP at 15% loss is 244 BHP, at 20% loss 254BHP. So your saying the TL's drivetrain loses over 25% of its power before it approaches to the wheels? I know 270 BHP is measured with the engine out of the car and is measured at the flywheel. I think Acura is overinflating their numbers.

That goes for the S2000 as well, your saying it loses over 25% through the drivetrain? No way man.

For example, an Eagle Talon 2nd gen makes 175WHP and the factory claims 210HP at the crank, thats a 20% loss and the talon has AWD which causes a larger drivetrain loss.

No way a RWD or FWD will lose more than an AWD through the drivetrain. You said you beat a Maxima with the TL? I have seen the new Altimas beat the TL's everytime. I have seen this numorous of times and some TL owners that own an Altima amit that its faster.

I dont know where you're getting ur numbers from and i think you're doing it backwards.
First off the TL is rated at 258 crank hp. U yourself said they lose from 15-20% through the drivetrain (which is the general average). Thats an average of 17.5% drivetrain loss.
With simple math: 258 x 17.5%= 45.15 HP loss to the TLs drivetrain. U then take 258hp minus the 45.15 horses u lost due to drivetrain. What does that equal?? 212.85 WHP.
So it seems the factory is on point with their ratings.

258 - (258 x .175) = 212.85
whereas the .175 represents 17.5% average drivetrain loss.

Oh and for the comment on me beating the maxima. Ive raced 2 so far, a manual and an auto and have never lost to any of them. All i have is a K&N drop in. Even if u calculate power to weight ratios, the TL comes out on top.
Couple that with the fact that it also comes with an LSD (in 6mt models) ....i think the TL should come out on top most of the time. Of course it also depends on the driver.

I guess the SAE reading is more dead on compared to Acuras original horsepower rating of 270BHP.

The TL is a beautiful call don't get me wrong and it looks better than anything Nissan can offer, but the cheaper apparently less powerful Altima always beat it power wise.

The Altima does weight a lot less than the Maxima so that could explain it, but aren't Altimas rated at 245HP?

The maxima does weigh 400 lbs more than the altima so that might be why its faster. I didnt get a chance to look up the specs on the altima tho nor have i ever raced one with my TL. I did race one with my accord but u already know the outcome of that one!
