i was wondering what kind of fuel injectors would be best to help hold boost at redline instead of slowly going back down..the 550cc, 650cc, or 750cc...and what else can i do to help hold boost at redline? thanks!

 

what turbo are you running? if its still the stock one bigger injectors wont help. the stock turbo is too small for our engines. the max psi you will see at redline with a stock turbo is 18 psi and that would be on a perfect day with only the best tuning. i need some more info on yours mods before i can help you more. boost falling off is just gonna happen it always does. what does your car fall off to at redline?

 

im still running the stock turbo...it falls off to about 16psi with the agp wga

 

that sounds about right. the only thing i could suggest for better boost would be a dsp (diablo sport predator). it will get you to spike around 19-20 and will help hold boost a little better. but like i said with the stock turbo it will always fall off at redline. 16 psi is actually pretty good if you got to 18psi i would be surprised. some people have claimed to have a big wheel stocker (E1 S3K) hold ~20psi at redline but it has a bigger wheel and will flow more air.

 

thanks alot! What would you recommend for going stage 3 turbo? like upgrade wise in the engine internals? im very new to the srt 4 ive only had it for a few months so i have no idea what to buy for it! thanks for your help!

 

if you are going stage 3 then dont worry about internals. the stock long block can handle over 450hp and a stage 3 kit will be under that by a good bit. if you find a big wheel ported stage 3 then you would be alot closer to the 450hp but still not quite there. i would tell you to worry more about maintenance first before getting into modding. make sure your engine can handle the extra power first. do basic stuff like water pump, belts, tensioner. maby even a compression test just to be sure the engine is at its full potential.
