i have a set of RC 370cc saturated injectors ... whats the most HP i can safely run on these? thanks

 

not alot ... id say around 280

 

At stock fuel pressure and 85% duty cycle 200-220 HP.

At stock fuel pressure and 95% duty cycle 225-240 HP, but running them at that duty cycle is dangerous.

If you have an adjustable FPR and you raise the fuel pressure to 55 psi then you are getting 415cc's out of those injectors. At 85% duty cycle and 55 psi , about 225-240 HP.

At 95% duty cycle and 55 psi of fuel pressure I'd say about 250-273 HP.

Check out http://www.rceng.com and look in the tech section. You'll see why the high and low numbers I posted have such a huge gap in between them. I used a BSFC of 0.60 (turbo cars) to figure the lower HP limit and a BSFC of 0.55 (NA cars) to figure the upper HP limit of the injectors.

 

370's are good to 300whp maybe

 

what about dsm 450..are they good pass 300whp...

dude stop giving out BULLSHIT .


blueshadow is right 370;'s are only good to about 220 WHP

440/450 are good to about 270-280 MAXXXXXXXX and this depends on your tune how rich it is.

 

Not true. I ran 370's in my street car years ago and made 268 whp on a pump and regulator setup. Fuel pressure was set pretty high though from what I can remember.

 

inline pro as i recall runs 440's up to 400 WHP but they use a fat *** FMU to rais efuel pressure.


even then i dont like the idea its not safe or that reliable thinkin bout runnin high fuel pressure like that. plus it breaks down the fuel lines and causes them to crack.

 

Yeah, its a pretty crude way to do it, but back in 97 we didn't have many options.

 

my car made 215whp on 310's. 450's are good to around 300ish.
