it was really fun to drive and very power full ,but I am very confirm that this kit given 0.8bar boost on my car ,it was a little bit danger on our 12.1 compression ..the project haven complex , have been order the snow performance water injection as a safety to high boost..by the way our stock ECU can support the the boost or not...the answer is yes..I have airflow monitor on my car..when the car run in low rpm ,the airflow is around 14.3 to 14.7,after the boost start,the car magically add the petrol ...when 0.5 bar,I have a airflow on 12.5 to 12 , when 0.8 bar ,have even only 11 .1 airflow...it was awesome..

^Exactly what I was going to say! That core will be good enough for 700+whp!
I assume that oil cooler is for the fluids running through the S/C unit itself?
I see your oil catch can there; good work!
Any thought to removing that intake box and getting a modified short ram intake on there?

But if no one boost more then 0.5bar over here,then I may reduce it until 0.5bar for safe , I believe that kit come with a small toy look like a air stopper or air reducer( I don't know how to call the name) it can less the boost until 0.5bar,..will go dyno next week and see.

I'm really curious if we can handle over 7.5psi safely. I've hit 8.2psi before after over tensioning the pulley and it was feeling great, but I STILL have not gotten my wideband installed. If your air fuel ratios are good, get it dyno'ed. I might end up throwing a smaller pulley on mine to up the boost when I swap my blower belt now

Yes ,i have the OBD2 monitor in the car ,so i can monitor all the data and even fault codes,water temp ,air temp,intake air temp..etc.
However,i have some problem now , when I step hard on the throttle and the engine revs and s/c boosts up 0.6 to 0.7 in a sec , engine knocking happened (rattling sound) , it only happen when suddenly hard-accelerating and the boost is climbing rapidly , The funny thing is ,it not always occur when i do that ,until today i have 2 time this problem .By the way When I'm on normal drive and boosting at .8 bar it seems to be okay.
Does anyone know how to solve this problem? Is it because there need to add extra fuel inject or tried retarded the ignition timing ?
Now i am using RON95 petrol and will changer to RON97 petrol see whether any improve or not .
