Z3M roadster S50 question

[Z3Mroadster]

Why do you want to wheel spin? You could cause catastophic damage never mind destroying your tyres?

Read more of my previous posts.

I bought a car recently and I wonder whether the car full power or not...

I think this is performance related not wheel spin related, I think he is saying that the car is underpowered and looking for some help.

Z3Mroadster if this is the case your car should do 0 to 100km in less than six seconds.

Take it to a dyno, but if you can do this don't worry .https://zroadster.org/threads/he-said-lets-go-out-for-a-few-doughnuts.9389/

It is possible that the lack of power.
The problem is that I do not have anybody to compare...know factory 0-100 5.4 s

This does not help

Maybe measured 100-200???
12-13 s???

mine easily spins up in 2nd...even on the strip with great traction.
if your struggling to get it to spin in 2nd your down on power

mine spinning up in 2nd

Also, to be able to do that on a drag strip takes even more power/torque than on a regular road so you should have no trouble breaking your tires loose going into second gear! JIM

Can someone help with the pressure vanos?

 

[Z3Mroadster]

I measured the pressure the Vanos...

At idle on cold pressure is 102 bar...

At idle on 90° pressure is 101-102 bar...


When suddently I add gas pressure drops to 85 bar and sometimes on 70 and again go back to 100 bar...


Do I have a problem?!

Vanos is repaired prior to 8000 km in Dr.Vanos!

 

[Z3Mroadster]

Vanos test ok!

I put the new TPS and MAF and I have not done the calibration...

I've done:
-Oxygen sensors
-spark plugs
-tps
-maf
-rebuild vanos+vanos filter
-valve clerance
-ultrasonically cleaning Injectors
-filters injectors
-cleaning ICV
-Vacuum hoses
-rubber intake manifold(6)
-cleaning throttle
-air temperature sensor
-water temp.sensor
-all filters+TWS
-non-returne valve (EGR)
-rubber injectors
-other rubbers

And some parts...

Does anybody know?

i think you would need a dyno run to see what the engine is actually producing ...is there
any problems with the drive chain?

Inlet camshaft 60.2°
Exhaust 0.0°

Ok?

Why do you ask for the chain?

take the car for a dynometer to determine the actual true power output .its the only way you will be happy

I understant all

 

[swamper]

exactly what Miller said ,,,,you need to find out where the power loss is instead of just replacing parts,,,,this power loss could be anywhere from the engine all the way down to the rear wheels

I replaced almost all parts

In my country there is not a good mechanic for this car...That is the biggest problem!
