What cam timing are you running now?

With my setup, I am still running the stock cam gears but I have an exhaust cam on the intake and I now think this affects the cam timing.

I looked at the HKS cam cards for the exhaust and intake cams and I think my intake cam timing is retarded quite a lot from the stock setting.

I think this is what gives me the high peak torque of 6600rpm, as you can see on the graph, in the thread you linked.

It is quite significant and I can feel it when I drive.

(obviously the torque and power figures are wrong but I think the curves are useful)

If it helps, I can dig out the cam cards and figure out the exact timing.

When I worked it out before it was quite a lot, perhaps 6 degrees.

So, I would recommend, double check your cam degreeing, then set maybe 5 or 6 degrees retard on the intake, and stock timing on the exhaust.

Then it will rev

(:

Hi Vashy,

I gave the camcard I found to the mechanic and he made the timing.

What I know is that I have the 264 on the intake side and the 256 on the exhaust side.

So do you suggest switching them or is it OK if I keep it like this.

On the other side I have the gears on both cams so I am able to use both of them whereever I want.

Your thread was very helpfull and I read it so many times to understand completely.

Do you think the ecu is capable of providing enough fuel at wot and do you think my CR is to high for the timing already set in the ecu.

I am trying to find the hidden maps that was talked about in your thrread but not successful until now.

If you can find and send me the cam cards it will be very helpfull and I will be thankfull to you.

The base timing is 10 degrees with diagnostic mode on.

When I remove it it is around 15

- 16.

I will check the tps because I did not check it yet.

The idle is not smooth and the afr is around 12.5 sometimes it goes up to 13.2 and I wil that car is shaking like valve setting are not correct.

when I push the gas pedal I feel that the car is not responding happily, if I rev it around 3000

- 3500 to the limit it is acceptablebut from 1000 rpm you can feel the hesitation easily.

By theway I also lightened the fly wheel around a kg, lightened the rods

(not to much), pistons are already light and the crank, flywheel and clutch balanced all together.

All rods are within 1 gram difference.

All pistons are the same weight.

so I am still thinking what is wrong with it.

So in order check my understanding, you said that you installed the cams with standard cam gears.

The timing is the same with standard cams

(or not) and after setting it you dialled exhaust cam stock timing and intake 5 degrees retarded.

How powerful is your car, is it as good as a modded pug 106

(around 140 hp), mine is not

Thank you very much to everyone responded

Hope I can find the answer.
