hey guys i dont know if i need more pump or larger injectors i start to run out of steam at 5500 rpm cam is a 227/233 112 lsa, home ported heads intake and throttle body, i know that i need to replace my pump soon but it still puts down 43.5 psi, any suggestions on what i should do?

 

Go for a drive with the gauge taped to your windshield. That will tell you if you're running out of fuel.

 

Is it tuned for the cam? If not get one.

 

Yes its tuned the cars pulls very strong until 5500 rpm the. It falls on its face and won't go over 6k rpm

 

Shitty valvesprings? Other valvetrain issues? (wrong size pushrods, needs valve adjustment ect?)

If not, get a racetronix hotwire kit

 

well my fuel gauge doesnt work anyway so i need to cut a hole a check stuff out... as for the valve springs they were bought for a cc306 and are a dual spring so they should be just fine for this cam pushrods are stock size hardened chromoly units from comp cams engine itself has roughly 2500 miles on it and seems very happy i have lashed the valves ever 500 miles so far

 

Stock injectors?

 

Msd chip? Limiter? My first thought was valvesprigs.

 

Stock injectors and a 6200 rpm rev limit

 

Wonder if your running outta injector. Have you data logged your car? What's the injector duty cycle at?

I have some 30# SVO red tops I'm looking to sell... 140 shipped obo..
