Supercharger installed week ago and have some problems .
When I start engine on the morning, my car is very very fast,
but after 20-30 minutes my acura is much slower. And this problem repeats.

This is a dyno before supercharger:


This is a dyno after install supercharger:


PS- European Power - US HP
Nm - European Torque
I checked ACM and all is ok.
I need your help.
Could it fuel issue?

 

i jsut think that the engine is getting too hot to provide decent power. Try a water/methanol injection kit.

 

any ideas?

 

Any ideas ???? Yea, stay on the damn road. Look what happened when your TL got too much power.... you ran it into a field !!!!


Ok, calm down. JUST JOKING. You know us stupid Americans.


The only thing helpful that I can offer (however, I have no experience with s/c) is that the TL engine is very sensitive to the underhood ambient temperature. This is why I removed all of my plastic covers (including the underbody panels too) from my TL.

 

I believe the problem is that after 20 to 30mintues of driving, everything heats up to a point where the IAT causes the ECU to start retarding timing which causes a loss in power.

Try to relocate your IAT sensor to your intake before the throttle body. Or even better, fit a cold air intake to your supercharger and fit the IAT sensor there.

Many people find that with the relocated IAT sensor, the car runs much more consistent.

 

Thanks,
I'll try do it today. I'll check A/F too.
