Either the system has some restrictions (turbo, manifold design...) or the tune was not that great because spool up on that turbo is pretty laggy.

Its not the greatest turbo, and the clutch was slipping. Its a Sf turbo kit, El manifold t3 super 60. We all can't afford to get the best stuff as quickly as we wish.

his dyno graph is doing the same mine was when my clutch was slipping.

Mine made 200 ft/lbs of torque at 4300 RPM and held flat at 200 all the way to 6700 RPM. You could tell that the clutch was slipping pretty bad on the dyno. But it was extremely noticable on the drive home.

The dyno sheet showed it right away also. When the torque peaks low and sits flat, that is a pretty significant sign that your clutch is screwed up.

Once he replaces the clutch, he will see a significant gain on the dyno with zero tuning. His graph looks like the clutch started slipping, then got worse and worse as the pass progressed.

You have Exeedy organic clutch. Its not holding past 200lb/ft?
I have same clutch and 175lb/ft.
I thought exeedy whould handle more then 200lb/ft of torque.

I thought the stock one was rated to about 200 ft/lbs? Exedy should hold more than that....

that torque goes up quick

Yeah exedy organic was not made for boost. I got an act stage 3 waiting now.

03-Acura-1.7-EL

iTrader: (14)

Exeedy rated for 120% over stock.
my stock was fine for 6psi on t25.
I think Exeedy should hold your boost fine as well.
May be dyno is underrated??
It shows 200+hp's, but you are at over 300+hp? This may be a reason for sliping clutch.

did you have any problems with the belt tension? mine will not stay tight now.

Michalo187

iTrader: (33)

with the cam? yes you must modify the tensioner or you will bend valves

iTrader: (2)

What do you have to do to modify the tensioner and why is this needed.

drunkenmagnum

iTrader: (5)

what?!tell me more!

drunkenmagnum

iTrader: (5)

how do you do this i must know!

Michalo187

iTrader: (33)

Ok what you need to do is remove the tensioner, Then you must align the two holes that fit an allen head into them, After this when the holes are aligned you then must weld it together there. After this when you are ready you must just tighten the belt to where you would like and bolt the tensioner where the timing belt is firmly tight. After this you will no longer have problems with the belt becoming loose. The reason you must do that is because the valvesprings are a lot stiffer and stronger than the stock ones and the stock tensioner cannot take that. I learned this the hard way because my belt kept coming loose until finally i bent a valve. Let me know if my explaination makes any sense if it does not i will try to take pics or try and make a diy.

thanks - yeah pics would be great.
i will call the shop now.
rep for you

Michalo187

iTrader: (33)

Thanks I will try to get pics up or send you some. I just need to either remove my tensioner or so you with my spare one. Its pretty straight forward but i had to do this and thank god we figured it out or else we would have bent a lot of valves.

hmm i have been running the stage 2 NA cam and crowerr springs/ret for quite some time now and never had a problem. I have also replaced my timing belt and tensioner recently with new unmodified honda parts and still no problems. the stock tensioning spring does the job fine for me.

Michalo187

iTrader: (33)

well who knows. Thats why i never posted this problem because i thought maybe it was just my car. But the turbo and NA cam are different.

02fpcivic

What are the specs on your cam. I have a pretty aggresive custom ground turbo cam and the belt is ok with the stock tensioner. I also have upgraded springs, etc... Id think the springs would be more apt to cause tensioner problems than the actual cam.

Michalo187

iTrader: (33)

well who knows but i know not everyone has had this problem. I have the crower stage 2 cam. Once i modified it it has not happened again

iTrader: (97)

Look at the Cam he has for specs

what exactly did you do to the tensioner?

what will teh act stage 3 handle?
because im hoping for 230-250 wheel horsepower and im afraid my clutch wont handle it, im pretty sure ive got the act stage 1 or w/e.

Michalo187

iTrader: (33)

230 to 250 the Act Stage 2 could handle but just get the stage 3. Talk with Eddie he is a good guy he will give you a good deal. Eddie I just got my stage 3 clutch today. Thanks I will leave you feedback asap!

i could get one for around 35% off, my concern right now is to figure out exactly which one is sitting waiting for me to install........ you think just upgrading from the heavy duty to the extreme pressure plate will help?

pm me letting me know what your power goals are and future plans so we won't flood this thread with back and forth comments.
