i have a gsr motor with 12.5 compression with 230hp crank and im running 240cc and i was told by one of my friend that i need RC 310cc injectors.now i know my stock 240cc injectors are maxed out so i would think i need 310cc injectors but i run rich as hell as is i have a p28 mugen chip and a SAFC and i dont detonate so do i need the 310cc injectors will they help?

 

anyone?

 

Umm 230whp, 240cc and 12.5:1 cr and you are running rich as hell??? i don't think so.

 

What fuel pressure are you running right now?

If you get the 310's you should be able to dial them in on a dyno with your AFC.

 

you dont think so well my rich/lean gauge is always on rich.

 

and my fuel pressure is stock gsr regulator

 

The Mugen program is designed for a motor that has individual throttle bodies, insane cams and 13:1 compression and needless to say makes more than this "230 crank hp" figure you're talking about. Where'd you get that number from anyway?

Also, please elaborate as to what kind of tweaking you've done with your AFC. Have you had this thing on a dyno yet?

I work for DFE enterprises over here in Jax Fl and we have a motor dyno not a car dyno.and we got 212hp with DC headers and ctr intake cam and a gsr exhaust cam.now i have a JDM 4-1 header cleaned up in the inside of the header and crower 63402a in and we got 13hp out of those cams on a diffrent motor so i got those cams and we are thinking i have around 225-230 Crank HP

 

i guess no one is going to give me a real answer?

 

310's should be good. get teh 330's out of the prelude if you are peak and hold injectors. so basiclly get a auromotive fpr and tune it in you might possibly need to lower the pressure. you cant do that wit the B&M style.

 

330 i think is to much and i dont want a FPR i just want the stock one and i dont like B&M.and if i got a FPR i would get the SARD.ill get the 310cc injectors anyways because no one wants to give me a straight answer.every time i post a question on here no one answers me anyways.so ill just go ahead and get them.thanks for all your help everyone.there were over 50 people that looked at this question and there were 10 posts and no answer.

 

According to the tech section from RC engineering (rceng.com)
Say you have this 230 BHP at the crank, run a normal .50 BSFC for an NA, and like 45psi at the rail. This is hypothetical. Then, at 95% duty, you STILL need at least 313cc to cover it. At a more reasonable 80% duty, try 371cc.
Just running a few numbers by

 

Shut the hell up mike i allready got my answer from don i dont need 310cc in jectors if i did then they would work 29% more and i dont need that it would run rich.i would need 270cc injectors if you want 310cc then go ahead and get them.

 

LOL
Curses, foiled again.


Not hating, just stating!! LOL

 

thats cool go get your hater-aid
