It was about time to dyno my altima... so while I was at it, I took the new TL over there too... I was satisfied with the Altima and disappointed by the TL... But the guy said it's because i'm still in break-in period (is this true?) ... I have little less than 1000 miles on my TL... so I'll dyno it again at about 5000 miles to see what happens.
I'll leave the links to the videos for a day or LESS and then I'll have to take them off, because the server i'm using is very slow and i shouldn't even be using it to begin with so please, if someone can host these clips for me would be great.

gotta love that flat constant horsepower on the alty

Very interesting. I've seen 5AT TL dyno at around 210 hp. A couple of questions for you:
1. What kind of dyno did you run on?
2. Was the Altima's figures also lower than other AT Altimas were running at?
3. What are the size of the aftermarket Konigs on your TL?

Thanks for posting this information.

cM3go

seems a little low for the TL, definetly could be it hasnt full broken in yet

Enforcer

A1- I'm not sure the answer to that.. It was my first time I dyno my car... so I don't know the different kinds of dyno

A2- The Altima was about what I expected... I only have Exhaust, Intake and Mid-pipe, which are giving me about 20hp at the flywheel, (which sounds right, because 2002 altimas came with only 240hp)... I thought I'd have about 205hp at the wheels and the torque was what I expected, so it was almost like what expected.

A3- they are 19x8" and each wheel without tires weight 25 pounds... I donno how much with tire, but I think they were about 5lb heavier each.

I think maybe that the larger wheels might have caused some of the hp loss. If the Altima dyno is pretty accurate based on what others on altimas.net are getting, then I can't think of any other explanation. Then again, I also see you have aftermarket wheels on the Alty.

Enforcer

I just got a response from one of the altimas.net guys and he thinks that my altima's numbers are low too ... so I might have to try another dyno shop... maybe the dyno place has a problem and their numbers are off!!!

I will dyno both cars with stock wheels in about 3 or 4 months.

04acura tl

I thought the tl were getting about 240 to the wheels???

Enforcer

well.. not 240, but I think I'd seen stock dyno at 220... which sounds right...!! so i donno !!

PoochaKannInc

Stock AT dynos around 210-212

Stock MT dynos around 220-222

I think I remember this from www.vtec.net.

Enforcer

ouch... that just ruined my day

VQ35DE

If the J32A is anything like the VQ35DE, it'll be a different car after the 1st oil change. That area under the curve on VQs is a beautiful thing.

mhooven

A good rule of thumb is automatic tranny's have about 20-25% losses, manual about 15%.

For a 270 Hp Acura, AT losses should be between 54 and 68 hp giving dyno results for the AT between 202 and 216 HP.

For manual, 15% loss would give 229 HP on the dyno.

Brokedoc

1st oil change = break-in (3,000-5,000 mi)

The VQ sucks gas like there's no tomorrow.

MrGQDieselNY

I thought I read a post the other day from a while back that had the TL at around 230-240hp on the dyno?

jimthegreek

I've seen numerous dyno's for the TL in AT run around 205-218 at the most.

rescueswimmer

Thanks for the info. Although I would have waited a little longer before I started hammering the engine but thats just me.

the much bigger wheels definitely make a huge difference. rolling mass is much greater. the TL really needs to get broken in some more. vtec.net dyno'd the TL at about 227, if my memory is still good. someone in this forum had a dyno of his TL at 233 with a CAI.

stealth

I can't believe that! 190hp, that's 80hp loss from crank, that's ridiculous.

Brokedoc

Correct me if I'm wrong, but a CAI will suck in cool outside air on a dyno with slight improvement in numbers but should perform even better when cold air is being rammed into the intake at highway speeds....right?

F23A4

Maybe but the TL isnt far behind (or ahead):
Car & Driver 600 mile road trip (observed fuel economy):
04 Acura TL - 17mpg
04 Infiniti G35 - 16mpg <----VQ here.

takkar

The exhaust on the Alty sounds nice...what kind is it?

Alan Barreuther

As a friend said,"You can dyno your car and drive around the corner to get a burrito, come back and do it again and get +30 hp or -30 hp." What difference does it make?

tommyt37

Are you kidding? 17mpg? Damn I wonder if that was all city driving?

zeezz

damn i just made my own 400 mile road trip and i got 27mpg with 81 average mph... 5.5K miles

TheOne305

the average 5AT dyno was 210HP that ive seen and it takes up to 5k to break-in but i've heard 10k to fully break-in(thats what i've heard) but i probably wrong about the 10k.

Well its almost the end of the month and I still have plenty of bandwidth, so here is Enforcer's TL Dyno Movie rehosted.

here is the dyno result from vtec.net on a 04 tl 5AT bone stock.

i need someone to host the image and post....vtec.net is forcing a log in for the article. thanks!!

PoochaKannInc

I can see the pic from what you originally posted. But I have hosted it below if anyone has trouble with the first pic. It is smaller though.

F23A4

I'm sure there was some "spirited" driving during those 600 miles.

3PUTT

212 HP / 206 TRQ to the wheels is pretty good for a 5AT.

Aegir

Cool thread. Thanks for posting the pics and clips.

You really can't compare dyno readings from different runs with different conditions on different machines from different companies. This dyno was a Dyno Dynamics and many of the numbers being discussed were from Dynojets. Dynojet readings seem to be fairly consistent machine to machine, but there can be a big difference between them and dynos from other manufacturers. That doesn't mean any of them are right or wrong. There are a lot of articles about this...

Aegir

I dyno'd 229hp stock and 237hp with an Injen CAI (6MT) on a DynoJet.

Acura claims up to a 15F drop in intake air temperatures.

Aquineas

That's a myth.

Aquineas

Enforcer, my TL got much stronger as time went on, and at 16K miles it feels pretty strong. It's not as strong as my Alti was, at least torque-wise, but feels good for an auto. Have it dyno'd after a couple thousand miles.

Aquineas

You're not wrong. My car definitely felt stronger at 10K than it did at 4K.

F23A4

OK. I just got home and saw the videos. TL sounds totally sweet. But the Alti sounds VICIOUS!!

Teh Jatt

sorry for going lil offtopic but

i raced a guy with 2002 or 2003 (i forgot) altima 6speed (stock) and we did few runs, and i did beat him on every run.

I have 5AT
