How are others run side mount coolers with 300 or so HP? I'm not sure how much power I have though... I just know that 440cc injectors were not enough.

I will also try to clean my IC as I have never did this. I don't have catch tank, so it can have some oil in it.


You need to calculate the engine airflow and pressure ratio at your designed engine revs and boost pressure. That point is then placed on the compressor map of your compressor so you can check if the compressor is the correct one for your engine design.

Never run breather hoses back into the inlet of any turbo engine used for racing as it will raise the octane requirements of the engine. Use a catch can and vent filter.

Oh my... That's engineering which I am very bad at...

Thanks for advice for catch can, always wanted to fit one, just never did. I hope I will not blow my engine during my first time attack.
