660cc injectors

[turboedspyder]

I got some 660cc injectors and was thinking about getting an evo3 16g turbo. But would those injectors be enough for a 50 trim ?

They would be big enough until you want to run high boost then they will probably hold you back

660 cc Injectors will provide up to roughly about 400-450 horses. If you know or think that you're not making that much power 660's will go a long ways.

Your stock fuel pump certaintly won't supply the 660's.

Also if you have any desire for safety you will consider 80% IDC your cutoff flow rate of the injector and not run it at a static flow rate. Also when calculating the flow rates, it is impossible to know how efficiently your engine produces power. I suggest guessing based upon a range of .50 to .60 BSFC.

RC Fuel Injection

This gives your 660's a potential crank horsepower range of: 402 to 335 .

So yes you could get some good power out of the 50 trim. No the fuel pump cannot handle it, you will need a minimum of a 255lph (preferablly a high pressure model). Mostly likely depending upon the turbo model, it could still produce more power than the injectors could handle.

^^^Like said, You should be fine with the 50 trim, unless you're completely maxing it out on pump gas. When I run my FP Green (50 trim) in the next few months, I plan on keeping my 660's in, and I'll be hopefully close to maxing the turbo out. If needed, I'll get bigger injectors. But you should be fine. Make sure you have enough pump!

Crap! I was hoping to blast in here with formula and compressor maps with BSFC theory. . . .

<3 He's exactly right.
