i know this have been covered a billion times.. but dilema seems odd... i dont own a R, but i figured you guys would be a better help. i posted in the forum but didnt get any help.... here the break down...

2000 gsr. act s/s clutch and act flywheel with roughly 10k on it.

im not positive if my clutch is going... b/c it still grabs fine for normal daily driving.... But when i put on the A/C and try to take off from a stop, the rpm's drops extremely low...
Here are the Symptoms

1. A/C on and at a complete stop.
2. trying to take off, rpm drops to a point where car wants to stall out.
3. trying to keep the car alive and the rpms up.... I try to rev it up to 2-3g
4. its extremely sluggish to keep the engine speeds up from 600-3000g
5. it takes a lot of effort to try to take off from a dead stop with A/C on. car wants to die if i dont put enough revs into it.....


in order for me to take off normally.. i must turn off the AC. and everthings fine. clutch grabs like normal.... until im fully cruising, thats when i can turn back on the a/c. BUT i must turn off the a/c when i approach another stop and must to this back and forth action every time i have the a/c on
any idea?

 

I think it may just be the fact that you have the AC on with a light flywheel. I notice if I have the AC on at a stop, my rpm's drop cosiderably. What is your idle at normally?. you may want to raise it a little. I may be wrong , but this is sort of what I'm going through

 

if your clutch was going it would slip, Having the air cond on and having the idle drop has nothing to do with the clutch. Your problem lies elsewhere.

 

how high do you rev before taking off? you gotta raise revs a little with lighter flywheel.

 

it drives fine in the past with the same setup. just been acting up lately where car wants to kill herself.

idle is normal... 850-900

with a/c on... when i would try to take off with just torque alone... but it would just stall out... but with a/c off i could easily take off with just easing off the clutch.

with a/c on i would have to take off around 3g's

YEAH??? You sure about that? Do you have a lighter fw in you car?

 

i have a 12 lbs act. didnt have any probs in the past drove like stock.. but its just acting up right now with the a/c on.

 

yes i do.. do you?

 

so you are saying its not the clutch?

 

I say something else, what I have no clue...

 

thanks for your help

 

Comptech Al FW with ACT XT-SS and I drive it like it was stock. I can let the clutch out with out touching the gas. and barely rev over 2k to move from a dead stop.

 

i can't 100% back up what i'm saying, i can't really remember the difference other for the first week of getting flywheel and thats almost 30K now.. i'm much better at it now and don't really think about it, but i do remember having to rev higher to keep take off smooth or being much lighter on throttle at lowest of rpm..

 

I was told the way to test if your clutch is slipping is to do the following:

1.) Locate empty parking lot
2.) Car running in neutral at a stand still
3.) Put car in 5th gear and let the clutch out
4.) If car stalls right away, clutch is not slipping *significantly*; otherwise clutch is slipping.

Never tried this, so not sure how accurate it is, but I think it is a decent way to tell. Of course if you beat on the car, the clutch may slip under more "spirited" driving.

 

in another words what you are trying to say is...... put that beeeeeech in 5th. and if i can takes off and move... the clutch is still good?

 

Its definitely not your clutch, all the symptoms you listed dont have anything to do with a sliping clutch really...

this is how i would look at it..
every honda ive ever been in, the rpms jump a little and then drop when you turn the ac on b/c it bogs down the engine a little bit
also durring ths ummer, all cars are harder to start and are slower..
so considering that you probably only have the ac on during the summer, your car will be a little harder to get roling from a stop, nothings wrong- its just how a belt driven ac works

 

thing is this though... i know that when the ac is on.. the rpms drop slightly. but when my ac is on... the rpms drop to a point where the car will stall out...
the scenerio is this.... ac on, the car is at a full stop, in 1st gear. i slowly slip off the clutch (normally the torque will pull the car up to speed) the rpm drops to a point where it wants to stall, i give it more gas, but it seems as if something is trying to hold the rpms back...i turn off the ac. and i feed it more gas... and the rpms jump right back up to normal.


the only thing is that i can think of right now is. maybe my fuel issue...
does anybody agree?

 

My vehicle used to have that problem. It started to occur when a shop tighten my valves WAY to tight when i bought my vehicle in for a valve adjustment. After I took my vehicle to another shop and got the valves adjusted properly, it was too late. The damage was done.

I believe your problem might stem from a slightly bent valve or your in need of a valve adjustment.

If you want a quick fix, just raise your idle a little higher. I have a 6lb flywheel and dont have that problem. 99% sure that the clutch/fw is not the culprit of your problems.

 

but only occurs when my a/c is on though
when a/c is off.. it runs like a champ

dont know if this helps by here are my mods..
i/h/e
cams.. forget what cam timing is set at
forget what ignition timing is set at
fuel press set at 51+/- psi
vafc
act s/s clutch and fw
theres more but thats the basic

can you be more specific with rpm, as to how high do you rev and how low does it drop.. basically same thing you have said with numbers. but it doesn't sound like its clutch related.

also, does rpm drop or raise when gearing is in neutral and you put on a/c.. does the car ever die when you put a/c when in neutral?

with the AC on, car does not die when it is in neutral

with ac on... i have to rev it well past 2500-3500.. while at the rpm range... as i slip off the clutch, i can still feel the car bogging out and trying to shut off... in order to prevent that from happening... i feed it more gas.... or basically shuttting off the a/c..

at first i thought it was the clutch... then thinking... could it be a fuel issue... i know a/c puts extra load on the motor...but it does not put that much load that it would try to stall the car out

 

fuel issue? ignition timing maybe?
