what is the max hp 550 injectors can supply?

that tells me zero

 

dood, it tells you everything you need to know. dont be lazy and read the page and you will have your answer. do some research and youll find it.

 

OK what type of fuel? 91,93, or e85? im gonna guess its a 4cylinder. we will need more information. and yes fuel type does make a difference! Oh and the link he gave you is for you to do it your self! Since you are too lazy i will do the math for you

ok first convert from cc's to lbs per hour
(lbs per hour)*10.5=cc's
-call lbs per hour X, and you know the rest of the information so you need to find X

X*10.5=550
x=52.38

Next you need to find out what "horse power" your injectors will support at a given duty cycle. The formula looks like this:
(Injector size in lbs per hour)* duty cycle/B.S.F.C.*#of injectors=theoretical whp they MAY support, so i will fill in the places for YOU with the given information

52.38*80(a safe duty cycle)/.65*4=257ish

Your answer is 257 whp on a boosted car using a very safe duty cycle and B.S.F.C. if you max them out on a less fuel per horsepower you will be just at 350.

that link is a good one thanks i will save it as a favorite

 

^^ and it has a calcualtor on the page if your too lazy to do the math you just did.. Jeez, some people have to be spoon fed

 

Oh and on e85 with a bsfc of .80 it would only be about 210 whp at 80% duty cycle if you wanted to run e85.

YES i know .80 is high for a BSFC, but it takes aprox. .65 for a boosted car on 91/93 and 30% more for e85.

 

Was looking for a approx, that page looked like chinese to me. Thanks for being a nice helpful guy :/

 

lol im with hyperflow.. lollll some of us aren't that smart not calling you stupid or anything. we just want a answer lol. but i would estimate atleast 250-400whp 550's are good. some ppl might say more some less. my opinion.

 

the only way you are gonna make 400whp is to run more than 4 injectors. your "estimate" IS WRONG! I once had similar questions. And if i was told i could make that much power on that injector size i would be mad if i bought them and could barley make half the power i was told. I build cars with one purpuse, GO FAST! That is why i run e85, and run 1200cc injectors. I was told my 780cc would make the power i wanted on e85. They can only support about 350ish. Yes 350whp honda is quick but not as fast as i wanted to be

 

cool story bro and thats a opinion. i have seen it done plenty of times.

 

310cc 200-220whp
440cc 220-325whp
550cc 325whp-380whp
660cc 380whp-425whp
750cc 425whp-475whp
880cc 475whp-525whp
1000cc 525whp-600whp
1600cc 600whp-800whp

 

its on rywire link

so my guess was not that bad after all.

 

The easiest way to figure this out is to use the equation where 6cc of flow (total) = 1whp

That way, if you have 550cc x 4 injectors = 2200cc total
2200cc / 6cc per whp = 367whp on gasoline

If you're planning to use E85, there is a 30% conversion factor. That way 6cc x 1.3 (E85 conv factor) = 7.8

If this value is used in lieu of the gasoline value, you will get 282whp.

**All of these values are approximations and should only be used to guess-timate injector size**

 

thanks for clearing up the math i learned something new today.

 

yea thanks for the math deff helps me out..
