2011 5.0 whipple charged 630rwhp 47# injectors?

[jayman33]

Really? Sweet.

 

[chuck@evoperform]

Ha ha, I thought the same thing. Is he complimenting you or being a smartass.

I bought the 3.250 pulley and JLT intake, wondering if the 47lbs injectors and stock fuel system will work with that. What do you guys think?

Stock pump has been able to hit over 750 with a KB setup with 75lb injectors and a BAP

We are using the 47's in our blue car and it's making well over 700 rwhp. We have a dual Walbro return system in the car, so that lets us push more than normal, but with enough pump you can get some good power out of them. With the stock pump, they are done at about 600 rwhp.

 

[chuck@evoperform]

thats kinda scary

 

[mr. anderson]

are you guys running around 100 psi fuel pressure with those 47lb injectors? that would equate to around a 75 lb injector if I swag the math in my head.

100 psi equals 47 * sqrt 100/39.15 = 75.11 lb/hr injector

which would support 785 bhp @ 85% duty cycle or 685 rwhp safely
if your pushing it, 900 bhp @ 100% duty cycle or 774, rwhp (hoping the weather doesn't cool off and the computer asks for more injector as the air gets more dense.)

let me know if im off on this.

That's why that was so scary......

thats kinda scary

Mr. Lund seems to be ok with it...

 

[carbd86gt]

I did forget to mention that we are also running C16 in the blue car, that does make a difference.

 

[2011Black5.0]

Yeah I'm gonna go with 72# ers 3.25 pulley that should be good for now u think I should make easy 620 or better be good enough for now.next year built motor baby!!!!!! then will up the boost

OMG Yes, since the Rest of us are running 93 with a Splash of Octane boost(Xylene here). C16 is an O2 Killer! Also costs like $15.00 a gallon last I checked...You got DEEP Pockets..lol..

 

[jayman33]

Awesome, just need to find a fuel system that isn't going to empty the pockets.

 

[Mystickeith50]

Jay, I'm not sure how much power your looking for, but you will be ok with the 47s with no bap with 600.

 

[jayman33]

600 is about the most I would push out of it. After that I plan on getting a new block and fuel system. Thanks bro.

 

[Twinscrewgt]

Why a new block?

 

[Mystickeith50]

That's what I plan on doing...drive it till it pops(so far so good) then go forged, more fuel, and moar boooost.

 

[jayman33]

^^^ what he just said. I plan on blowing it eventually.

 

[Twinscrewgt]

I'd build it before it breaks. New blocks are about $1100

 

[jayman33]

I'll just go all out and get a new livernois block

 

[5PointOHNO]

47's with my Lund tune.... over 600 to the tire.

 

[COYO TT]

Doesnt it depend on where he is redlining? Are you shifting at 7k or 7500?
