Hello

I have a question that concerns Tuned Port Injections.

I have a 5,0 TBI engine in my `89 Formula 305. I have modified almost everything that I could to improve the performance ( camshaft, heads , prom etc etc) , but I know that to gain real power well over 300 hp I will have to switch from TBI to multipoint injection one day. So my question is what multipoint fuel injection is the best for my engine on the market. Is it Accel Super Ram or Injectrix Street Ram or other accel system or maybe Holley Stealth ram or Edelbrock ProFlo.
The second question is how much the power will increase over stock TBI.

Thanks for any replies.

 

The stock TBI is extremely limiting.

I don't know if emissions is a concern for you or not.

The StealthRam is not emissions legal, but I can't say one way or another whether it will work or not, because I haven't read much about them on a 305.

The SuperRam is definetly too much for a 350, even with heads and a cam... it just doesn't have the displacement for it and it will most likely end up slowing it down. A modded TPI would do you nicely.... fully ported and matched base runners and plenum would do really well on your engine.

 

You mean a 305 right?

 

Yes, I meant to say that the SuperRam is definetly too much for a 305. My mistake.

 

I wouldn't nessicarily say the SR is "too much" for a 305.

It might be overkill, but Not "too much"

 

I think superram wouldn't be worth the money for a 305... however, what if you just got a ported TPI plenum, LTR's, and a better base EG: superrams base manifold.

All better than stock TPI but not to much for a 305 either. =)
