This is my Dyno from January of last year. The car was bone stock and had 3,000 miles on it. The Dyno was done in 5th gear...why, who knows?
Results:
Horse Power: 231 HP (SAE)
Torque: 210 Ft/Lb (SAE)


NEW RESULTS W/ AEM CAI and COMPTECH EXHAUST

Horse Power: 250.7 HP (SAE)
Torque: 228.6 Ft/Lb (SAE)

The torque peaks at 5500 rpm. That's normal right?

What's the TL's redline?

Here's another one from an '04 TL MT. The torque (max 5,300 rpm) and horsepower are around the same. Dynoing in 5th gear may be the issue. I think what may have happened in my car is the speed limiter may have kicked in because it ends at 6,600 rpm at 153mph. It should have redlined at 6,800 rpm.

The scales between the two graphs are very different, mine is way more exaggerated in the Y-axis.

Here's one more form K&N. It shows max horsepower at 6,100 rpm for a stock '04 TL 6MT.

It might also because you didn't use a Dynojet which is what most tuners dyno with. Unfortunately it's like comparing apples to oranges.

Here's TOV's '04 TL 6MT Dyno on a DynoJet (DynoLab uses DynoJet). Again, Max torque is around 5,200 rpm and HP around 6,200 rpm.

Weird. In your's and the Dynojet they decrease after 6200 but they seem to level off or increase in the other 2.

It is weird. I do know the early '04 TL's were having problems with their ECU, including mine. At high revs, the CEL would flash. Then Honda/Acura came out with a fix which included remapping the ECU. I took it in and Acura took care of it. Now I wonder if I re-dyno it, how the HP and Torque curves would look.

That's a nice peak gain for hp. And the torque curve was raised.

Anybody else notice that the dynos in the first post say they are flywheel numbers, not wheel power? Shouldn't the numbers be higher then they are? What am I missing?

It's wheel (hub) horsepower...not flywheel, even though it says flywheel. There are less losses because the wheels are removed from the vehicle and the dyno is connected directly to the hubs.

Yes, both dynos were on the same dynapack. The first dyno was on a much cooler day than the second. However, because it is SAE correceted it shouldn't make too much of a difference, IMHO.

It's about 2 to 5% higher on the Dynapack compared to a Dynojet.

Turbo Magazine did a comparison on a 350Z:

In summary:
Turbo Magazine Dyno Dash Comparison Chart
Dyno HP TQ
Dynapack 249.4 242.8
DTS 257.6 556.5*
Dynojet (Win) 235.8 227.8
Dynojet (DOS) 243.7 237.2
Clayton 265.7 240.6
Super Flow 228.9 226.6
*measured at roller without accounting for gear reduction

You should put it on a Dynojet when you go next, might make for better comparison since your numbers are probably around 10-15whp higher on the Dynapack. Good comparison though, i/e looks like a very worthy investment on the TL. Did the TL-S/CL-S see those kind of gains as well?

There's a second gen CL-S, 6MT that has similar gains on the acurazine site.

w/ the following mods:
OBX headers
Tanabe exhaust
AEM CAI (my filter is dirty as ****)
VAFC- just dyno tuned. Gains were: 10 HP and 8 TQ

It ran:
250 HP at the wheels, me 250 HP
214 TQ at the wheels, me 229 TQ

I've got quite a bit more torque. Maybe he lost some with the headers...who knows?

Dyno:

I've got 19" rims, not sure if it would do too well. Maybe if I had some stocker wheels, then we can compare it to someone's baseline (stock TL).

aren't those better numbers than what G35s pull? I thought G35 6spd is faster than TL?

nonetheless, very impressive numbers man. props.

It's in the neighborhood of g35 in terms of horsepower. Howver, the G35 produces more torque.

Below are some numbers from a Dyno Day on a Dynapack (same Dyno I used). The cars are almost stock except for intake and exhaust. Notice their mods and their numbers. The coupes definitely produce better gains than the sedans. Here's the original file G35 DYNOS ON DYNAPACK

Exactly why you take mag times with a grain. They're not the undisputed answer to a car's speed. Sometimes "real" drivers exceed or can't achieve those times.

The best way to see what a car does is to see an average of the actual owner times. Mag time are kinda useless because they often exceed (as in the auto TL's, 300C's, and 6G AV6's) or lack what a real driver could/should do (LS1's, some VQ's).

From what I've seen, the 6spd TL's seem to be good for low 14's at around 97-98 stock, while the autos are more often in the low 15's at 92-93ish. Mag times are different, but that's what the actual TL off the lots does and what the averages are. Always best to use the actual owners to compare, you never know with mag times.
