Latest Dyno

I was hoping for 240hp and 200 lb ft but this is the best Kourtney could do today.
I'm pleased with the results but I need more power!
Forgot to mention that I shot some video of the pulls.
Yes, I know that the curves with headers and headers w/cai are fairly equal in the lower portion of the rmp band. I don't know why it cut off around 7200 rmps vs. 7400 on the other 2 pulls.

Cool Astro! I talked to my performance shop and they really don't think too highly of the vafc but I'd be very interested to see your dyno.

Type-s, what can i say?

Thanks Eric. Let me guess...math was your favorite subject?
I have the tables you requested but it's six pages long. I'll scan and email them to you as soon as I get a chance.

<font face="Verdana, Arial" size="2">Originally posted by EricL:
Mike: You runs look good...

Well, it flywheel power checkout time

Calcs for flywheel to front wheel (assuming 20% loss):

296 - (296 * .20) = 236.80 HP wheels

Mike, your very close to the magic 300 mark!


315 - (315* .20) = 252.00 HP wheels

Reference to non-CA 3.5L Gen-I engine

Looks like your 19 HP shy of the 3.5L (at the flywheel).


OK, now is time to compare torque (remember, thats what wins races and pink slips [I didn't say it] )

Mikes run with CAI and headers

248 - (248 * .20) ~= 198 ft-lbs (at wheels)

Mike's torque 248 @ flywheel

260 - (260 - .20) ~= 208 ft-lbs (at wheels)

Reference to non-CA 3.5L Gen-I engine's 260 ft-lbs @ flywheel

AND, your 10 ft-lbs shy of $5000

Not a bad day. After seeing the spark plug dyno, I wonder if you would get another 3-4hp.

Congrats!

It looks like our cars lose more then 20% at the wheels. He lost about 22%, so he should be around 300hp to the flywheel. Nice runs by the way. You guys inspire me.

assuming 260hp at flywheel as Acura has claimed Mike lost about 23.5% to the wheels.

198.8/260= .765 so loss is 23.5%. Therefore, Mike is actually at about 311hp at the flywheel.

nice dyno! finally confirms what headers and an intake can do. .

this reminds me, someone said comptech is making an "ice box" intake? does this use the factory filter? bah, i'll just call them tomorrow. .

Congrats for the Excellent Dyno.

Well regardles wether it 20.5% or 23.5% loss.

Let is look at it this way:

Headers for $1300 installed.
CAI for $200.
==================
For $1500 you get an increase of 236.5/198.8 =18.96% Inrease in performance.
(i.e., 260x1.1896 = 309.3 HP!!! )


I love it! CL-S cost $32k for $1,500 or 4.69% more you get 18.96% Inrease in performance. A very good deal for me.

For now I have a CAI. Headers sould come with my Suspension Upgrades!

I can't answer this question for sure, but I know I've seen pictures of Comptech's white CL-S. It had 18" BBS rims on it. I believe they were the BBS RKs. I think those BBS rims are a little lighter, but who's to say whether or not they dyno'd the car with those rims on them?!?!

BTW, yes I will be going soon, just one more addition to the car and I'll hit it...

They are on order and in transit right now (just checked the tracking info). I'll check then out and see how they fit and what the difference is in diameter. Anything more than around 10% ratio change and I won't do it.

But IMO, there is well more than 10% overage in the charging system. More on the lines of 30% at least.

So, if all goes well and fits accordingly I will schedule a trip to the dyno.

How many horses do you expect to gain?
Let us know about the differences in diameter too.
Don't suppose you be up for a before and afte dyno w/the pulleys?

Your math looks silly. It's backwards.
296 - (296 * .20) = 236.80 HP wheels

Looks like you're guessing the max hp, then
calculating the net and comparing that to
the dyno.

((236/80) * 100) = x; x = gross hp (20%)
((236/77) * 100) = x; x = gross hp (23%)

Both are correct, it's just how you look at it.

Honesty I have no clue on the gain potential. I wouldn't want to speculate until tests are made, there are too many unknown points. If I had made a run before without the belts on at all I might have an idea.

When they get it I'll mic both the AEM units and the stock pulleys for comparisson.

As for the comparisson dyno runs, it depends. I'm going to look into what tools and time will be needed for the swap. If I can swap them within 30 minutes with hand tools I will certainly do before/after runs as I did with the intake. It just costs a little more for the dyno time and is well worth the knowledge gained.

On the Accord the stock alternator pulley is about 2 3/4 inches and the AEM pulley is 4 1/8 inches. The stock power steering is about 5 1/8 inches and the the AEM pulley is 5 1/2 inches.

I'll save my brain cells and let someone else due the math.

Scalbert, which pulleys did you order? I hope you didn't order the accord v6 pulleys. They are different from the types s pulleys and don't match up perfectly. The pulleys designed for the type-s will be released in a couple of weeks. They production units were test fitted today. They just need to be sent out for anodizing now.

You know, the guy that did all of the plug tests had a point. He said, I do all of this stuff, since I like helping people, but all they do is compain. I asked him why he bothered, and he said he wanted to share.

I felt that way, but every day, I keep getting worn down. So, congrats -- you can claim victory for ridding me from the board.

You do the math, you are much smarter than I am. I wont ever bother to:

1. first, spend the time to figure our the exact result, then put it in an easy to view format.

2. for being so stupid to believe that a set of calcs with clearly defined data could be bashed.

You must be very proud of yourself...

I do understand this, which is why I was checking them out first. I don't mind investigating the differences. I had also heard the same thing about the intake, using a Accord/TL unit, which has been succesfully installed in my car since last summer.

My main objective is to determine these differences and convey this information to the forum. Just call me impatient...

Could someone measure their CL-S pulley diameters and post them? I'm curious to see how much they differ from the Accord. My guess is that the alternator pulley would be even smaller than the Accords, since the CL-S has more power to play with.

I'll take home my Mitutoyo micrometer tonight and make the measurements. Well, that is if my car is finished at the dealer. Otherwise it'll be tomorrow (damn sunroof rattle...).

Just went and picked up my car. I made some quick measurements of the pulleys. This is rough considering the caliper didn't want to sit straight, if/when I pull them I will be able to get actual measurements.

Alternator pulley: 2.70"
Power Steering pulley: 5.14"

The alternator and the power steering sizes seem to be close to what BNut saw on his Accord. Considering both measurements are within a tenth I would guess them to be the same.

Next question is the mounting. I beleive the alternator has splines but the power steering pulley is keyed?? We'll see soon though and I'll check the manual tonight.

Geez... I just like computing hp, salary, tax and stuff like that. Just thought I was making it easier for people to figure out their hp on their own. This way you can nearly do it in your head. I'm sorry if my post to show an easier way hurt your feelings.
