Did anyone else notice that the horsepower rating for the new TL is based on the power made at ONLY 6200 RPMs!!!

Well, one of two things is going on here:

1. The engine is way underrated and makes closer to 280-290HP at 6800-7000RPM. It always did seem fishy that Acura only squeeked 10hp out of all of those new engine mods.

-or-

2. The engine totally runs out of breath after 6200RPM. This would seem somewhat uncharacteristic of an Acura engine. Where does the stock CLS dyno flatten out without headers?
If this is the case then the fact that we will not be able to put headers on these new engines will cost us A LOT of untapped horsepower.

What do you all think?

They were able to get to the next level of lower emisions standards. I think a cam swap may be needed on this one.

They lowered the compression ratio. I'm not sure about the exact figures but its still pretty close to the TL-S.
Other than that it doesn't seem as if they made any other significatn mods to the engine other than its a ULEV. Don't quote me on that.

ModAddict

I think they raised the compression ratio,..11:1

AcuraTLSFan

I think the 270 HP at 6200 is correct and it's not underrated.

The power rating PEAKS at 270 HP ot 6200 RPM, and after 6200, the power will start to drop off until redline. But the drop in power is still better being in a lower gear then shifting to the next.

power3dfx

our cars make 260 at 6100 i think, and stays constant till redline. it actually drops off a bit from the peak they say. i think acura wanted more enviro friendly cars this time more than hp. if they kept the lev status the same as type s, they could of easily pulled it to 275 or above. last point i want to make is that with the integrated exhaust manifold, and a cai from factory, makes this new engine tuned out to max. from factory.
this leads me to think that there isnt much that can be done to make the new 04 tl much quicker. they already took away header and cai mods, and there is a better exhaust. higher compression ratio makes it even worse for boosting.
this car is a kind you should buy with a spec package, and never touch it. j m know thats what i would do!

TL_Type_S

agreed. the peak hp is only 400 rpms short of the current gen. 3.2L engine.

typeR

according to the few dyno's i just looked at if the peak rating on the new TL is indeed at 6200 then yes they did short themselves because the dyno's ive seen peak at 6500+/- i expected there underarting to come from using regular unleaded like the accord only to see a nice gain when switching to premium

No headers, no CAI is possilbe on the 04 TL.. the only mod is the UR Ultra SS kit worth some 10 WHP. It is (MAYBE) the same as the Type-S. The new TL has 130 Amps Alt rather than 120 ( Type-S). Or... We alre left with a new SC and that is it! if you get a fully decked A-Spec TL /NAV!!.

I think with 11:1 CR we are limited to to 5 PSI worth some 50 WHP. now to start at 225 WHP and Add Some 50 WHP we are at 275 WHP... At 6-7 PSI we may hit 300 WHP.

It's really a dissappointment to know that our hands are going to be tied with the new model Acuras.

Why won't a CAI be able to be put on this car?

Nashua_Night_Hawk

It is already a CAI system.. a K&N free flow filter is enough to extract couple HP.

JZ

Also--when reading all of the engine mods on the new TL you would certainly think they would be good for more than 10hp since a CAI alone on a CLS gives you nearly that.

Now, if the new TL runs out of breath at 6200rpm than it appears as though their use of the integrated manifold might be very constritive and really stealing a lot of power--maybe even moreso than in the current CLS. Maybe they had to do all of that engine work just to make up for the power loss due to the integrated manifold. Thus, adding headers to this engine might, in theory, make even more power than what is seen with the current CLS/Comptech header combination (which is already pretty impressive considering I can't think of any V6 cars that gain as much HP from simply adding headers--I think headers for the 350Z only give like 8hp!)

Bummer.

Zapata

nope they raised the compression. 10:5---->11

JZ

I was thinking the 2004's cold air system is just like that on the stock CLS--which is a "quasi-cold air intake" because it gets air from behind the front wheel with the resonator. Thus, just adding a Comptech filter gives no gain if it is the same set-up.

I doubt seriously that the 2004 TL has any sort of true CAI.

So JZ I suspect you will be trading your whip in for an 04 6spd HPT, yes?

Just let me know, I'm here when you need me.
(And since that sucker will be at MSRP for months, maybe I can help you out on your trade-in value).

Nashua_Night_Hawk

Acura claimed with stock 04 TL they lowered the intake charge temp by 15F. 6% more free flow than the current type-S.

Nashua

JZ

But they said it was 15F less than typical engine compartment air--which is probably the same that it is now. And, 6% ain't nothing.



JROCK--no, no 4 doors for me! I'm eagerly awaiting the possibility of a new CL at the end of 2004 and then probably pick one up in Spring 2005. That would be the correct timing for me. I still love my car and would have a tough time parting with it.
In fact, I plan to spend a good bit of time giving her some TLC today!

If the new CL has the right stuff like the 04 TL does, IMO, I will definately be in!
