Hello
Cam are catcams for turbo conversion
270/250
Fuel is ron 95
Here log
https://youtu.be/DtURfXHwmPM
Stock intake manifold and throttle body
Now i get about 530 hp and 670 nm
Ps lifter are hydraulic
What happens if you raise the boost? i think 530hp is plenty for just 1,3 bar of boost.
Whats the compression? i could imagine it would start to knock somewhere around that power level on pump fuel. what does your exhaust system and exh. mani look like?

Hello
I am sorry what do you mean breaking up or valve control?
- - - Updated - - -
I have cat cams for turbo conversion 270 250 with stock head and stock hydro lifter and stock valve.
What's the clutch setup in the car? Do you have a log file of the pull?
Hello in link Youtube in previous post you can see log
I use f1 Cooper clutch.
Engine has eagle rods and wiseco piston
Cr is 8:1

hello
Is common problem valve float on m50 turboed?
On rpm gauge i not see strange rpm jump usual when clutch slip.
same for tires...when it slip i feel big black smoke but i not feel it
spark gapped at 0.4 mm but on afr log i not see strange behavior of afr.
what yu can see on video i posted boost has little fluctuation
Is it a vanos or non vanos cylinder head? I can't really tell much from your video but I do see the AFR and pulse width fluctuating slightly. I also noticed that the torque drops off sharply at 5200 rpm on the graph but the log shows the pulse width is still increasing till nearly 6000 rpms. Something is not quite right there. I think I would try a different set of coils, boots, and spark plugs
engine is non vanos
but i have bought used head on ebay
i do not know how check if from vanos or not engine

is useful play dwell?

dyno is lps2510 cartec rated for 400 kw
Non vanos heads have double valve springs and vanos heads have single springs. If you do have a vanos head the cams you have might be too aggressive for the single valve springs. I think that’s unlikely the problem but it’s a possibility so I wanted to mention it.
What dwell are you using now. The stock coils work best with about 4.5ms dwell while in boost
i open valve cover and check.
dwell is 2.5 or 2.7 as i remember i check also

ps dropping down of power was present also with stock cam
hello i checked and
i see 2 spring one inside other
dwell is fixed at 2.7 mm and spark
duration 0.9
i attach screenshot and photos

how many mm do you sugfest for gapping plugs?
what do you think about spring and dwell?
