I have a question the TL have 258hp or 270 ???? because the consumer report said 258hp and i have seen 270 in other places and im not sure??

 

I was thinking 260 but I'll wait for responses. Mines an 03 type s

 

Both are right...sorta.

I had an '04 TL and it was 270hp

But in an effort to standardize how HP is measured...Enter the SAE (Society of Automotive Engineers)

It is the same 3.2L engine, but now it is 258 SAE hp.

That is where the confusion comes in. I'm not sure when this exactly happened and when things were re-rated.

search...

 

i search some said 258 and other 270 !!

 

Wait till you find out what the TL puts to the wheels

 

I have heard that the 2004 have 170 and the 2007 258 because of the SAE but don't know

 

how many hp do you loose to the wheel like 30 ????

 

On 20s? You are losing extra hp right there...

 

yeah i know but i just want to know if the 2004 is 258 or 270 ??

 

about 15% so almost 40 hp....

youre losing even more with those 20's though.

 

lol look...


its the same engine from 04-08 for base tl's. the hp did not change, only the method that is used to rate the engine ouput. in 2004 the tl was rated at 270, in 2007 it was rated at 258. no year puts out more hp for the base model.

 

old numbers 270hp
new numbers 258hp

in 2005-6 they started with a more stringent hp rating....and that is why for a lot of engines, the HP figures decreased but some engines actually increased in HP (I believe that they were underrated to begin with)

 

on the 02 CLS it was 208WHP with 260 crank hp for a loss of 52hp due to driveline

if you use a 20% loss for the AT then the newer (04-06)TL put down 216hp with the AT (they use the SAME AT as the 01-03 cars) with 270crank HP

source: Comptech Dynosheet for a stock 02CLS

 

2004 is 270hp..but if u so wanted to know earlier, you should use google to your advantage

 

ok thanks !!! now i am clear !!! lol

 

forgot to mention that is the 6mt losses. 5at will be closer to 20% so more like 50hp

 

To the wheels is about 211 to 220 HP. Honda's and Acuras lost alot of HP on the SAE correction scale compared to some other manufacturers for example Infiniti. It basically states that Honda/Acura over inflated their numbers to begin with. I love when I see ads for 2004 TL's, that say don't buy 2005 and up TL's because they have less power

Also, the bigger size in wheels definitely loses more HP. Rotational Mass in some estimates is given a proportion of 1:10 vs. Static Mass.

Meaning, if your wheels weigh an extra 5 lbs. each, thats a total of 20lbs (5x4) of rotational mass which is equivilant to carrying a 200 lb. (20x10) passenger at all times.

I notice a huge improvment in pickup when I throw my 17's back on from my 19's. Night and day. The bigger the wheel the more power loss.

 

2004-2008 base model TL all make the exact same amount of power. the 04 and 05 are NOT any more powerful than the new ones...

 

All I know is, when it's time to sell my 04 I will put 270 hp in the ad, it sounds better.

 

Not only that, but more accurate. It was sold as having 270 hp. Thats how it should be resold.

Just like a car from the 60's. If it was 300 hp at the time, go with it. Forget Gross/Net and all the revisions

 

The new HP measurement of 258 began with the 2006 model.

 

I think Dyno numbers for the Base MT are 204-208 range. AT+ 20's.....

 

I agree with Ken here ... 270 sounds better than 258, period ... besides, who really knows the ins & outs minus the AZ crowd here ?

 

The 6MT base puts down low 220's on a dynojet. 5AT around 10 hp less.

 

Very few people seem to be able to comprehend this, unfortunately.

 

258 or 270 it dont matter cause a tl is only putting like 200 to the wheels at stock which is horrible

 

Not that it matters to me because that 258 - 270 HP was history for mine a while ago, but I wish whoever is incharge of the numbers would make up their mind. I can't tell you how many of my old customers would get me with this question all the time.

 

The 5AT lays down ~210 and the 6MT lays down ~222. That equates to parasitic losses of 18.5% and 14% respectively, when using the true crank figure of 258. That is far from horrible.

 

I think the new ones are heavier. A base 08 is ~3600 pounds while a base 04 is ~3400 pounds. So despite same hp, the older ones should be slightly faster.

 

damnnnn.... 40 for real???? so if you have a system what is that like 50 hp

 

Depends on the weight. 200-215 is our WHP for base TL's. Every 15 LBs added, you lose 1 HP.

Pre-Cat deletes and Jpipe adds about 30 WHP. CAI and Pulley adds 10WHP. Catback Exhaust adds 10WHP. Supercharger adds 40-50 WHP. 300WHP is like the goal for all TL's. The turbo charger than is in performance section is trying to get at least 350WHP on itself I think

 

Lmaooooo okkkay dude that's pretty bad actually 270hp supposivly engine produding 200 hp is fuckin shitt but ok if u think that's not horrible that's ok

 

I was under the impression that the base TL has 258 while the Type-s has 270

 

I have a headache.

 

It's a pretty simple concept...

 

Well i thought the 04-05's put out 433hp and the 06-08s put out around 450

Dude if you honestly want to know, just pay the $100bucks or so and go to a dyno. Honestly its just a rating. I can tell you that not every single 04 TL will make 270hp, Some will be a bit more or a bit less. I had an 97 Trans am WS6 that was rated at 305hp/325lbs at the crank. I put down in stock form 294/335 to the wheels shortly after i bought it. It was a factory freak i say. Still have the dyno sheets somwhere...I know some compaines underate there motors...

 

The 04 TL and the 05 and 06 TL have the same amount of power. The way the HP was calculated changed. The END; A simple search would have yielded this information
