380 or 450cc???

Hi,

I need help!

Should I change the injectors to 450cc? At the moment I have the JCW 380cc, arrive to the specs I have on MINI?

This subject from what I see is not unanimous, some users say to change injectors others say to keep the JCW 380cc, I'm confused?

Or not I should change the injectors?

Specs on my car;
Pulley Supercherger ALTA -17%.
Pulley Cranck ALTA +2%.
Pulley Nator ALTA +5%.
Cam NEWMAN.
Injectors JCW 380cc.
Intake JCW + Filter ITG.
NGK Plugs Iridium.
Detroit By-Pass.
Janspeed + Cat 200cell.
Cat-Back Milltek.
Intercooler GP.
Remap.


Regards,
Nelson

Talk to the guys at MYNES Tuning in CA. They did my work and they have had great success with a 550cc injector. I love mine and they have an awesome tune package to match.

Good Luck

Don't forget wheather you do the Mynes 550's or the RMW 440/450 it will require a tune.

IMO the mod's you have are def. pushing the limits of the 380's, esp. if you've had your rev. limit increased. I would think you probably could get something from a larger injector with your setup simply because you're probably running your 380's @ 100%.
