Today was 84 deg. car has 38k miles.

corrected #'s: 207.9hp,205.4lb/ft
does the hp seem low and can someone host the graph for me?thx.

hp looks about right, 20% drivetrain loss.

 

Mine put down 218whp/206wtq on a Dynojet. It was like 62* inlet temp though.

What gear did they dyno in? Because mine only read 210whp/210wtq when they dyno'd it in 5th, which is the closest to the 1:1 gear in the CL-S6. It technically is an overdrive gear tho (.976:1), and the final drive ratio is not too steep (3.286:1). I got more accurate numbers when in 4th.

Also, what kind of dyno was it? I can host the pics for you if you'd like

jtkz13,

it was a 4th gear pull,both runs . i will email the sheet.


xrunner,

i thought the drivetrain was little less than that, are you going to mir on sept 19?


guys, my front tires are almost bald how much would that affect it?

 

Having bald tires wont hurt the dyno numbers at all. It would be helpful to see the entire graph because humidity, elevation, & correction factors can all affect the numbers. What kind of dyno was it? DynoJect, Mustang, etc?

 

it was a dynojet, not sure on elevation although in this area it's generally around 300'.
humidity, i think was around 70%. i emailed you the sheet last night.

 

The drivetrain should probably be lower than that, but ive seen people say anywhere form 15-25% (not just for the CL). I would love to go to MIR but i'm away at school. I will be going to capitol on November 26th weather permitting when i'm home for thanksgiving though. mrsteve might be going then too.

 

thats a large margin for the drivetrain, guess it depends what day it was built. Too bad
u cant make it on sept 19. mrsteve already predicted he is gonna be the fastest NA
car among us.

 

my bad, mrsteve said the fastest period.

 

I didnt get the email give it another shot

 

email sent.

 

I got the email, but it is sideways and my stupid work computer wont let me upload it to any site that I can make it upright. I'll get it figured out hopefully.

 

yea,when i scanned it that is how it turned out and had problems making it upright
it either didnt work or pic degraded.

thx for the help.

 

Here ya go:



From the looks of it you start going way rich once past 3500 rpm, which makes your tq curve take a dive. Doesnt the variable intake open up at 3500rpm? Compare your tq curve tim mine, which stays above 200wtq all the way from 2500 t0 5k rpm.

 

yea that is what the mech. said. what could cause this because it did ok up to
that point?

 

That'd be a question to ask one of the engine tuner guys on here. It would probably be wirth the $$ to get a VAFC which allows you to control the a:f ratio via a controller in the cabin. Hows your fuel mileage?

 

up and down.hwy miles only its good city/hwy combo not that great about 240-260 on a full tank

 

The IMRC actuator is, without a doubt, busted. It should take a 5 lb/ft dip at about 3800 revs and come back up. Yours does not and that plot is indicative of a busted IMRC actuator.

 

He hath spoken! taketh car to thou dealer!

 

understood, would the IMRC also affect the hp#'s?

 

HP = RPM / 5252 * Torque

So, if your torque drops so does your HP. The amount of the HP drop is dependant on RPM and the torque loss. A 15 WTQ drop at 5252 RPM is a 15 WHP drop. That same 15 WTQ drop at 4000 RPM reflects only a 11 WHP drop. Now, that same 15 WTQ drop at 7000 RPM is a 20 WHP drop.

With that said, the power drops off up top without headers anyway but still not to the level which you were at. With a functioning actuator you would see in the 215+ range. But the peak power is not what you should be concerned with. You have a major torque deficit in the 4000 - 6500 RPM range which is where you really want it with this car.

 

thanks for all your help and knowledge scalbert. I am going to be down in atl for
thanksgiving and would love to see your ride if possible.

Are you a mechanical engineer? sounds like it.

glad you fixed that problem w/the IC, might need one myself one day.

 

Drop me a PM when you head down this way. And nope, not an ME, but I do play one at times.

The IC problem isn't fixed yet, but I am on the way to recovery.

 

Another CL-S at Altered Atmosphere. Was the tech some old grumpy guy? I didn't like him too much.

BTW: The date of the meet has changed. Please check the Meet & Greet Forum.

 

they told me a black one was there before,guess that was you. yea a old guy did mine, but he was pretty cool.

 

Yep that was me

 

what did you put down?

 

227/201

I've got lots of mods though. It's so sad how much the automatic soaks up the power compared to the 6spd.

 

scalbert, where is the IMRC located on the engine?

mr steve,whats next on the mods list?

 

Here you go, however the RPM is stated incorrectly. It should be 3800 RPM.

thanks,now i know what to look for.

 

If yours in infact broken, take it to Tishcer Acura to have it fixed. Mine died about a year ago and I went it, gave them pictures of the actuator working and not working. They know of the problem. You may want to call them ahead of time and tell them the problem because they will have to order the part; it isn't one they regularly have on the shelf.

 

i was planning to go to either pohanka or radley and definitely have pics of the part if
neccesary.

 

Dark Knight -> given the dyno curve plotted above, you should definitely notice a drop in power from 4K though 5K RPMS.

Start off in 2nd or 3rd gear at very low rpms, say 2K, and go WOT. You should notice a gradual pull, followed by a maintained pull from 4-5K, followed by another gradual pull from 5-7K.

 

this thread is almost a year old.....

 

Yeah,I forgot about this,the problem is being solved.
