is anyone using secondary injectors bigger than 1600-1680?

and what are the reasons for not using huge injectors?

turborotor

woudn't injectors bigger than that be used on top fuel cars. Is probably a fire hose if you have the pump for it

Just wanted to say that

like turborotor said. Hell you might as well just put a ball valve in there thats hooked up to your gas pedal

RXciting

yea man you could try running a steel braided garden hose to feed those things



just my 2 cents

You need sewer piping and 4 pumps to supply the fuel for them. Plus who needs bigger than a 1680?If you don't have enough fuel theres something wrong with you car.

i'm asking about the bigger injectors because i want to have enough fuel for 600whp with a T88 in the future. i have a PFC, and i wanted to know what are the limits for the secondaries. i know that the biggest you can run for the primaries is 1000cc.

my other reason to ask is because i don't want to use a rebic with extra injectors.

so far the highest i saw with the PFC is 2x1000cc and 2x1600cc and thats 5300cc. i think i might need more fuel for about 600whp.

i dont think you'll need more fuel for 600hp, with that injector size

1000 x 2 and 1680 x 2 will get you about 630bhp worth of fuel at 80% duty cycle.



On a side note, where do you plan on using 600rwhp?

i plan on turning my 7 into a drag car, i'm currently studying in the US but i'm taking my car back home to Qatar. we have a bunch of 700-900 hp supras and skylines that i want to keep up with.

I think 1600 - 1680 injectors are the biggest commercially available. Methanol guys use 8 - 12 or more of these, if there were bigger ones available I'm sure they would use them. Keep in mind for most cars that 550 cc injectors are HUGE
