Ek9 engine under power

I'd check compression first then cam timing as that's very low for b16b! or dyno was ****

Tried to check compression but my tester wouldn't reach down to the spark plug threads.

The timing is set as per the timing marks. Is there any tests that can be done with Hondata to check the timing.

U can change timing with hondata but your tuner would have done that surely!?

Best to take your car to another dyno just to make sure the one you went to is reading low. I have been to 3 rolling roads and have had figures ranging from 168 - 194 bhp

Dynos do vary massively in my experience.

Lot of people use that rolling road so think his readings are good. Gonna look at modifying my compression tester so I can test that and also check my timing.

Ok so looked at car tonight and it looks like my timing is off. When I set the cam pulleys the bottom crank pulley is slightly off from the timing mark. Gonna get that adjusted and see if it helps. Can't do any harm I'd think.

ok so I've had my local garage check the timing with a timing light and they say its fine. Today I checked the compression and all cylinders are reading the same 8bar.

So now I'm lost as to what the problem might be.

Anyone got any ideas

try the dyno without the cat back box.
