right now i have the stock pulley on my vortech. i was wondering if anyone knows how much hp the next size smaller pulley would get me. i am making 300hp 178tq at the wheels right now. and are there supporting mods needed if i switched out the pulley? i have the emanage ultimate. i know i would need to retune after. thanks guys

 

next size would be the 4.9" pulley which should get about 7whp or so.

 

ha ok well thats not worth it then...what size would get me a decent amount of hp, with the least amount of supporting mods?

 

ur at 7psi now? go to 9 or 10 psi and get a retune should be closer to 350 after that

 

You can't get a decent amount of hp unless you get all the supporting mods like, real engine management, bigger injectors, map sensor, clutch blah blah blah...

 

you can get a 4.4" pulley, which is about 10.5psi...you should be around 350whp. you will need new injectors if you are running the stock ones.

 

thanks guys. we are using the emanage because we have emissions. we also weren't planning on really increasing the hp so we didn't want to spend the extra money on the aem. to be honest i may not even add the smaller pulley just seeing what my options were just in case. but i like the sound of the 4.4". thanks for the help

 

you got pm
