pro charger pulley size

[Dlett0929]

Hi, I have a Stage II Intercooled System with P-1SC-1 , 850cc injectors. I currently have a 4.75 pulley. can i go down to a 4.50 pulley without changing injectors?

You should ask your tuner. Your probably safe as that is not a huge change, but I would want to know what the fuel system is and if it’s a 15-17 or 18&up

Thanks, just trying to do everything I can myself and just get him to put the tune on it.... it's a stock fuel system except for the 850cc injectors. It's a 2015...

Injector wise you should be good, but me personally would recommend a bap at the very least

Thanks for the help... the Bap is cheap so I agree... I'm making 592 RWH now and I'm just wanting to see what a little smaller pulley would do..... and stay on my small budget..

You will not need a bap for the hp numbers you are looking for

Recipe for the perfect storm, high HP, low budgets when it comes to fuel system and forum people that won’t pay a dime towards your motor saying it’s all gonna be fine. Good luck

Well don't believe it will be the perfect storm but hey I'm no conspiracy theorist.....knew plugs and one run would be all that's needed to see if it's running lean.... then if it is spend the money needed.... don't just throw parts at it.... but thanks for the warning....
