440cc's what are they good til?
 

I have some brand new Lucas 440cc injectors (didn't feel comfortable with used dsm's) and am doing a whole brand new build. What kinda power can these handle? I am looking for around 300whp. Do I need to upgrade or no?

Re:440cc's what are they good til?
 

gf's car made 348whp on dsm 450's, I made 306whp on some dsm 450's.. I'd so your ok to 300whp, they are not rated for that but it works.

ya, I know theres no real "rating". But thanks again for another answer to my questions, I thought they should be good enough for them.

Oh ya, finding a gf that loves boost is a hard find and a keeper.

jw if you guys have ever pulled your idc's with the 440s I'm just curious what they are with over 300whp

Re:440cc's what are they good til?
 

to measure the maximum HP you can use for said injector at 43psi fuel pressure 90%duty cycle:

size of injector (cc)/5 = HP per cylinder

so

450/5=90hp per cylinder

360hp

cant remember whether thats whp or at the crank
