Hello everybody,
I have Lancer Evo9 with 435hp- internal stock-tomei arms7960 (21,7psi-27psi in overboost)-cams cosworth 272-o2 dump-exausth all 70mm without kat-direct hks suction kit kansai-Stock ecu-denso720cc-bigger fuel pump
I’m going to install Spark tech Cdi pro 12 with supply powered by dynatec arc2.(I’ll buy it used with a special price,that is the reason of the installation)
I would like to know:
Which will be the concrete benefits(power,torque,throttle etc.)
The possible problems (also after some years)
Because I want do this upgrade but I don’t want lose reliability because I want turn on the car and drive no problems and care.

Thanks everybody and sorry for poor English.

 

Uppp please

 

You'll be less likely to blow the spark out with a CDI box. Probably not necessary until a bit over 500whp.

 

Thank you for reply,
I know it’s useful but I’ll have it with a special price..
and about lose reliability thank stock coils? because I want turn on the car and drive no problems and care.

regards
