They claimed 270 until it was changed. What do they now claim?

Anyone dyno a stock car?

Auto if it makes a difference.

Thanks

 

It's 258 now, but the HP has never changed. What did change is the way HP is now measured.

For a stock AT 3G TL, I'd say (total conjecture) that you're putting down ~ 230HP to the wheels.

 

If he is stock hed be lucky to be putting down 210 to the wheels. IHC has his dyno at 210WHP and 183WTQ I believe all stock.

 

Thanks.

I was aware it was just a measurement difference, my fault with the wording. I came across the info multiple times, until I was searching for it today haha. Couldn't find it anywhere, and HP isn't long enough to pick up on the forum search.

I was informed that a J swapped hatch is making 230WHP so that's a good estimate.

 

Well that's a little disappointing, but oh well I'm not tracking it.

 

I see.

 

As long as your happy with the TL's performance then thats all that matters. Richies V3 Jpipe will give you 15whp though so you would be at 225whp just with that!

 

Its 258HP from 04-08 with the 3.2 liter, however I want to know what they did differently in the dyno testing. I don't want assumptions, just real information on what was different about the dyno testing. For those that are old enough to remember or know about cars made back before 1972, they used the Gross Horsepower rating, then the SAE net numbers came out and the horsepower numbers dropped quite a bit. I thought the SAE standard was established 38 years ago. How come they revised things in 2005. I want to know what they started doing differently. My 04 Auto isnt stock, but with an intake wrapped with thermo wrap and an under drive pulley, the car put down 227.2 HP and 198 lbft of tourque to the wheels (SAE corrected), thats on a dynojet with 86 degree temps, and 50% humidity if that gives you an idea of what these cars put to the wheels.

 

From my dyno trips the 6 speed losses about 40 hp to drivetrain and the auto about 50-60 hp.
My comment about my 06 MT when I got it was " like driving a rocket powered cloud"

 

My dyno is in my sig. 210hp to the wheels on a 90 degree day bone stock. That works out nearly perfect for the typical loss through the 5at for 258 at the crank.

What was changed for '06 was the engine being dyno'd had to be run with the intake and exhaust that was going to be on it in the chassis it was actually put in. If any of you have been in an engine dyno room, they usually stick the dyno exhaust right over open headers on the engine. New ratings are run with the entire exhaust and intake system bolted up.

The TL would likely be rated at 370+hp by the pre-'72 standards.

 

I'm pretty close to that 370 #, I just need to find time get it retuned.

 

Yours would be something crazy like 500hp by the old old standard.

 

The '04 and '05 produced 270 HP. You can't go backwards and restate those numbers simply because they were accurate at the time using the method which was in use then. Were you to sell the car, you would not need to advertise or tell anyone that your engine was rated at 258 HP because that would not be true - for those models.

Yes, they changed the method used to rate their engines, but that has nothing to do with the '04 and '05 models. Think about it. It would be the same as saying that if you were born in 1980, you are now 30 years old but next month, they change the calender so now you show up as being born in 1975. Does that suddenly make you 35? I don't think so.

 

Sure can change the numbers to reflect proper horsepower. Similar to the EPA fuel mileage change to more closely represent actual driving conditions, The 2004 TL was originally, 5AT 20/28, but now 18/26, 6 M/T 20/30 now 18/28.

I guess you could ultimately say the early TL has 270HP and sees fuel mileage of 20/28 and wouldn't be entirely wrong as there is paper to back up, but in reality it’s not factual by today’s standards.

 

Yep and when people start adding oversized wheels/tires subs and amps it just adds insult to injury!!!Just keep it above 5k rpms and you should be fine!!!

 

The '04 manual was EPA rated at 19/28 for MPG. My point is that if we apply ex post facto rules to our engines, then where does it stop? Yes, I know that the rating method changed after the '05 model year. But that does not mean that the ratings were wrong in '04 and '05 because that is what the method in use at the time indicated. So if someone today says that their '04 TL is rated at 258 HP, that would be in error unless they included an asterisk to explain themselves.

That's all I'm saying.

 

Tell me more about the EPA fuel economy change. I didn't realize it affected the TL's numbers. Going from a bad memory, I'm almost sure my 5at '06 said 19/28.

 

It wouldn't be an error though to state that the 04 TL makes 258crank HP because that is what it makes. The error was made on Acura's part to state that the engine made 270HP when it doesn't. They were inflated numbers. The 04-07 TL will dyno the same. Infiniti/Nissan had the same issue.

 

The funny part is some of the underrated cars like the Z06 gained 5hp from the new standard. The imports seemed to be hit the hardest.

 

Never quite understood that, but I believe the Infiniti G series gained some HP also.

 

It lost HP due to the SAE standard.

 

isn't this a repost?

 

 

in that case, please refer to this thread about the tool called "search" and you may have heard this one..."google" (ooooooo aaaaahhhhh)

Thanks for everyone's response.

I happened to use that thing you call "Google" and searched the forum... Sorry to inconvenience you with this thread my good sir, I can see you have a busy life.

 

my 5AT 06 had 20/29 on the sticker. thats odd. ill check my sticker when i get home and post it.

 

Interesting. When I wrote the 19/28 post earlier, I got that information from the sales brochure for the 2004 model year which I still have in my trunk. However, I just went out and retrieved my Mulroney (Monroney) sticker for my '04 manual and it does clearly state 20 city, 30 highway for my car (build month = first week of July 2004). So I have two different sets of figures and since the Mulroney sticker is the official sticker which appears on the car, I'll go with that.

 

I'd rather lose 15hp than have a car thats sounds like that

 

Comming from the subru scene, Seeing builds etc. the same builds on a different dyno is going to cause a HP discrepancy. There is no standard dyno, and some dynos read higher/lower than others. But really its just a number,cars with way less hp are sometimes faster than cars with more HP, so keep that into consideration.....

 

The j-pipe will make very little difference to exhaust tone.

 

I'm pretty sure the black TLs got 270hp while all others got 258...

 

 

amen brotha! haha

 

ya.. barely notice a thing!!!

thats a jpipe and a 6 banger honda.

and it sounds like dog poo poo

 

Nope, I see at least an exhaust on there. If you have everything stock, with only the j-pipe, sound won't hardly be altered.

That car has no cats. That car also has an aftermarket exhaust. That's more of what you're hearing, not the j-pipe.

 

hmm.. okay... if what you are saying is true, then it seems like a good thing. I just dont want a car that sounds like a tricked out 4 cylinder. So, if it really does deliver 15 hp more without a bad sound, (like 99.9% of the custom exhausts) then heck I'd buy one. $$$$

so the question is.. does a "no cat system" really change the sound...?

 

Eliminating the cats causes the exhaust to get raspy. The j-pipe is the single most effective bolt on available for our cars. It's a pain to install/uninstall, but it's worth it, more than any other bolt-on.

 

ok... but why does your avatar associate the 10 commandments with the first 5 to "God" and the second 5 to "men"?.

I don't agree with that. Its ALL instruction to men.. and to live without these extremes.... The 10 commandments are only extreme limitations. Its not a "preferred" way to live. It's only absolute limitations of tolerance from him that is above...

So I would suggest changing your Avatar.... Don't say "God" vs. "Man". If anything, its all from God to men. Each command is specifically what MEN should avoid and what we should do.

As far as the Jpipe, I never said it wasn;t the best mod. Its all about the sound.... thats it. ( or lack thereof )
