2nd gen v 3rd gen
Not a race, but the acura site lists the 2006 TL with 258 hp. Is that right?

If we are 270 with a TLS, I thought the 05 was 280.

What happened? New measurement methodology?

 

TLS is rated at 265...not 270. the 04 3rd gen TL was rated at 270, but they now have new standards on how they rate the HP and torque - I believe they now have all the accessories on and functioning also vs before just the bare engine - therefore, HP #s could be down some eventhough they are the exact same engine.

So probably if the TLS was rated based on the new standards, it would be less than 265

 

Exactly. The 2006 TLs are being rated via SAE Rev. 8/04. The prior models were under the old SAE standard.

 

i thot tl-s was 260?

 

yeah, Type S is 260

 

the old way was to measure at the flywheel i beleive, whats the new way?

 

OKC, OK: What is SAE net (Rev 8/04)? What's the different with the old SAE?

James Healey: SAE is the Society of Automotive Engineers, which sets various industry standards (how to measure power, how to calculate interior space, etc). The SAE standard on measuring power was revised earlier this year, requiring automaker to account for power losses of some equipment (e.g. power steering pump) that previously didn't have to be taken into account. The effect is lower some power ratings on '06 models across the industry, though there's no change to the engines or their performance. They've always had the new, lower power, they just go by advertising a higher number under the old standard. Net refers to the power measured with all the stuff in place (accessories, exhaust system, etc.). In the very old days, the measurement was 'gross' -- the engine running without any power-robbing features that it would have when installed in the car. Not very honest. The net part's not new. SAE net power has been the standard for years. It's just the tougher details of the new standard that make power ratings lower.

ya no kidding...I dont know why I put 265...oh well.

 

the cars are just as fast, they have the same HP as before, There is just now a different way of calculating the SAE hp which in this case makes teh TL's hp rating lower (its hapening to alot of cars that are now using it. Gm actually has been going up showing they have been under rating their engines

 

maybe one day we'll actually get the real HP the wheels show the road.... until then we'll have stupid math calculations to go along with the engine's HP rating.. "well this trannie give 15% loss, and this one get's 26%,"

If they were really smart they would dyno each car coming off the lot and print the recorded dyno on that car's VIN info. That would be cool to buy a car and be able to see exactly what it dynos, eg..257.6HP at 5700rpms 218.7 Trq at 4700rpms..

They do that for high end amps... eg. "tested at 714.63watts" it would be cool to see it go into cars too.

 

So the new measurements sound like they begin to give more realistic numbers and I love the idea of putting a dyno pedigree on each car. What a great sales tool.
Amp makers do this? Bourbon makers do it also , Jim Beam has Booker's which is proofed per barrel and is bottled at barrel proof 121.8 or 122.3, etc.

 

Yea that would be nice. The best way for HP ratings is IF the SAE standard was at the wheels, and not what the engine on a stand with all the accessories hooked up

 

What humidity/elevation/temperature/etc would the wheel dyno be at? I'd rather know the power without anything on the engine AND the power with everything on it..that would tell you a lot about the whole system.

 

0% humidity, at sea level (0ft elevation), room temperature (25 Celsius), You know they can always establish a "standard". Anyway, I still like the idea of hp at wheel, then the engine by itself.

 

whp and the crank HP numbers would be awesome. then tuners can understand what capabilites the car really has if there is a large disparity in those two numbers. say for example 260crank HP and 200whp then you know the engine is losing a lot of power because it either isn't breathing well enough and there is too much parasitic drag from the accesories, belts and pullies. but the big numbers speak volumes to the public and automakers won't change unless the mass opinion changes. like would you want a 1/4 hamburger sir?(even though after it's cooked it is not close to 1/4lb's weight).
