I want to do a before and after dyno on my 04 TL 6mt. Ordered AEM CAI, UR pulley, and Thermal spacer. I took my car to a shop with a dynojet. I'm very pleased with the results.

My first pull: 226.36hp/206.61tq
My second: 225.39hp/205.46tq
My third: 330.89hp/210.57tq (after 5 min break)

Here is the dyno sheet on the last pull!

Sorry can't get the pic to come up.

did you mean 230hp in your third pull? but either way, nice work, can't wait to see what happens after your mods are installed!

Sorry guys, miss print. My last pull was 230.89hp. Thanks for the catch mickey!

BTW, the guy at the shop was very impressed with my numbers for a stock car!

Kracker

Yeah, I was going to say that was an awesome third run...

I was almost ready to order everything you got

3rdGenA-spec

nice numbers. where can i get the pully and spacer from?

pohljm

Isnt this a base run dyno w/o mods?

Are all these results after, or before?

iTrader: (4)

probably before....right?

I got the spacer from this site: http://www.outlawengineering.com/tech.html

I got the pulley from Josh of Excelerate Performance: http://www.excelerateperformance.com/

I got all the CAI, pulley, and spacers installed to day by a local shop! All I can say is another satisfied customer!

First of all while reving the car, it sound wonderful (growling)! I was afraid that the car was going to sound louder! Unless you WOT pass 3k, you won't notice anything aftermarket! And it revs easier now!

Second of all, my car has more low end power! I see why you would get better gas mileage. During normal driving, acceleration is effortless!

BTW, I also wrapped the CAI with a heat shield for insulation. I guess I wouldn't be able to tell until the weather warms up again.

I'm scheduled for another dyno run on Tuesday. I can't wait to see the numbers this time!

does the thermoblock spacer keep the cold air from fitting right I just don't want to purchase then find out my cold air won't bolt up thanks.

lookinco

The thermoblock spacer will not affect the cold air intake.

Here is t0talacuratl's dyno sheet. (I am hosting it for t0talacuratl)

Tuesday cannot come fast enough for me! I wanna see the after numbers! You will be using the same dyno correct?

stock diameter pulley, or underdriven?

t0talacuratl

iTrader: (3)

I know! I can't wait either. I have been enjoying my new found powers though! The drivebility is so much better! I am using the same dyno shop also.

I have the underdrive pulley. I didn't know the stock crank pulley was so heavy! Does anyone know the weight difference? The UR has got to be only a couple of pounds!

Inaccurate

Oem crank pulley = between 7 - 1/2 or 8 pounds.
Used a bathroom scale with a readout to the nearest 1/2 pound.

The UR Pulley (underdriven) = 15 - 1/4 ounces.
Used a food scale with a readout to the nearest 1/8 ounce.

t0talacuratl

iTrader: (3)

The OEM pulley seems heavier than that. I believe the UR pulley's weight though.

Well, just came back from the dyno shop today and again very pleased with the results! Here is what I got:

Mods: AEM CAI, UR pulley, Thermal spacers, and Thermotek intake heat shield.

Before mods results: Max power=230.89/Max torque=210.57
Run conditions: 52.37 deg. F, Humidity: 16%, SAE: 0.92

After mods results: Max power=241.46/Max torque=222.29
Run conditons: 62.53 deg. F, Humidity: 22%, SAE: 0.96

Gains: 10.57hp/11.72tq


I will have my dyno sheet posted when the shop e-mails it to me.
Question? Since I've lost around 11% of power from the engine to the wheels, does that mean my engine power is around 270 now?

CleanCL

iTrader: (4)

why was the SAE adjusted on the 2nd run w/ your mods? also temps/humidty were higher. because i would think you should see closer to double your gains. i would think at least 20whp/20lb-tq w/ cai, pulley, and spacers.

whats the thermotek intake heat shield?

MichaelBenz

iTrader: (2)

Internet seach brings thermotek as a furnace mfg or something?

Teddybear

im asuming this was at the wheels. so.. how much pwr would be at the crank? id think it would be more than the 258 that acura rated it as. cuase it used to be what... 270? then now the sae rating puts it down to 258.

hollandca12

WOW,

That's pretty deflating! Agreed...I would have figured more HP/TQ gain than 10. What gives? Nitrous anyone!

pohljm

I think your SAE needs to be matched up for a proper comparison. The thermotek heat shield I believe, is the insulation around the CAI tube.

MichaelBenz

iTrader: (2)

Ahh....ok! That makes sense now. A bit overkill IMO...AEM CAI's are coated with a heat resistant coating I believe? But I guess more couldnt hurt?

t0talacuratl

iTrader: (3)

I don't think I would have gotten more with just the mods I've done. Looking at my dyno sheet, power and torque increased evenly across the board. From that info and how much better the car feels, I'm very happy. Keep in mine, I don't have any exhaust work done. If anyone have seen someone else with the similar mods with different results, please let me know. Otherwise, I'm not disappointed.

The correct spelling is Thermo-Tec. Sorry guys! I got the idea to do the heat shield from this thread. I'm all about keep the engine as cool as possible. It will be more effective when summer comes back around.

i'm not saying your results are bad, i just think numbers wise you probably gained more than it says on paper.

Here are t0talacuratl's new dyno sheets. (I am hosting the pics for t0talacuratl)

It's called Thermo-Tec and one of a number of online vendors sell it.

2004 TL

I do not understand why your car measured so much lower than mine on the dyno. I had mine tested in two sessions and it was consistant within 3hp and 4 ft/lbs between all of the runs (6 in all). Mine was measured with the wheels on, fan blowing on an open hood, in 60 degree temps, 60% humidity, and a cool engine to start. I know that there are differences between machines, but 48 hp? I think that you numbers are low. What are your acceleration times and speeds? That will tell you just as much as a dyno, or at least give credibility to the numbers. If you were seeing 300 hp in a 3500 lb car, you should be able to get through the 1/4 mile in the low 13's. But if you thought you had 300 hp in a 3500 lb car, and could not break into the 13's, then your power numbers are wrong. Thoughts?

iTrader: (1)

Yours are the highest #'s I have seen for an N/A TL. It seems like your using a dynapack dyno. They seem to put out the highest numbers. If your not, then what kind of dyno are you using? With your mods you should be in the mid 260's on a dynojet.

2004 TL

Thanks for your response. I do not know what it was called, and I can't find my printed reports to upload onto the thread at the moment. I believe that my hp/ft-lbs ratings are correct or I would not be able to achieve the time to speed measurments I consistantly see as noted in my signature. I have mentioned in other threads previously that about 2 tenths in my 0-60 and the 1/4 times can be attributed to my attenuation of the clutch and shifting style from the old racing days, but nevertheless, power to the groud creates time to speed. You can't have one without the other. So regardless if my numbers are right or wrong on a dyno, they are sufficient to produce the time to speed numbers which validate my claim. Remember, the measurements were not "coached" or rounded up. Rather, they were rounded down, and in fact they are the lowest numbers recorded on all 6 runs. If we are assuming that there is about a 15% loss in the driveline, the engine is probably producing about 340 hp at the crank.

Honestly I could not care less about this except that it makes for good conversation.

And with only those mods you are getting the same amount of torque as the guys that are blown? There MUST be something wrong with that dyno or you have a factory freak.

2004 TL

I have no idea. Maybe it is a "factory freak" but the time to speed measurments don't lie.

I notice you have lateral G's listed....where did that figure come from? I got a dyno and I never got any kind of "lateral G" measurement whatsoever? Also have been to the drags....and same....no "lateral G" measurement?

pohljm

let alone an "average" lateral G??

whats this?? 340 crank HP not F/I, never happen.

2004 TL

I am guessing about this point, but I am not willing to argue it further your honor.

"Average lateral G"

This was performed on a very tacky section of pavement with very sticky tires, turning left and right for two full circles. Tire pressures make a huge difference. The gas tank was near empty, and I was the only one in the car so there was no extra weight other than my body weight to affect the measurements on the G-timer.

With the Nexen tires I am seeing measurements of .88 or so.

2004 TL

G-timer

See my response immediately above for your answer. I am not fabricating any confirmed measurement, rather just reporting data. I am to old to bs anyone.
