That power run looks much worse than the one on the log you sent to me. It might be worth doing 4 or more runs to see what the graph looks like. Alternatively due to your power levels a dyno run at somewhere like EFI Parts might be worth considering.

Rain has stopped plaY again Are you talking about the file I sent yesterday Martin ?

[CHILL Gone DUTCH]

I'm not 100% but this slight dip has been there for quite sometime even at stage 3 but less Noticeable Going to get some 3rd gear runs done when weather allows What kind of things could cause this internally of the engine ?? Cams ? Is anyone else running the zzp stage 2 cams if so can you share you ignition settings with me

[CHILL Gone DUTCH]

There is very little knock No extra power is gained by putting more ignition in tried a extra 3 degrees and no change but does get knock It's been put to me it could be wheel spin so going to try a third gear run Problem is with that is the speed I will be going when I hit limiter So private long road required

  If your boost is consistent, can you see any strange things in wheel speed vs rpm's in the logs? (wheel/clutch slip...)   I think you had this dip in all your logs? Something head/cam/exhaust related?

Exhaust was changed so unlikely to be exhaust Nothing internal of engine has changed So head or cams is possible what do you Think it could be ??

[oakmere]

Power and torque look correct compared to Nicks firs harrop run at CS but there graph is smooth. http://z22se.co.uk/t...-too-far.11634/ It might just be 2nd gear runs with that much power. I can't believe that did that run on std Pistons.

This one Martin

 

 

Think  a trip to a dyno might be necessary soon 

[oakmere]

That is the one. My graphs often look like that when doing a power run on certain roads which have no obvious bumps. I only have one section of road that gives smooth graphs and Peter still shouts at me for not doing at leat 4 runs.

Extra weight in the car may also help somthing I have plenty of but you car scares me now😁

[CHILL Gone DUTCH]

which road martin 

is there any houses there as ive been moved on for disturbing the peace a few times now 

[oakmere]

The A51 from the Tarvin roundabout. It is on a hill but you can do one run down one run up. As you head down the road it straightens up for the run. You can the turn at the junction and come back to the roundabout. The road isn't lined with houses.

can you enlarge the 2 max rpm runs?

[CHILL Gone DUTCH]

its consistently at 6000 rpm when power rather drops off or flattens out 

[NickB787]

when I'm back in the UK I will be able to get some work done on mine, worth booking joint dyno time Chill have you looked at my runs? can't access any here

No, from the rpm/speed logs...
