Hilborn 2 3/16 inj question

(1/1)

kiwikid:
Hi Guys , new to this forum,  hopefully a simple question , I have a sbc 352 inches   I rev it to about 8800 I sold the crower        2 5/8 injector that was on it ( some time ago  )  I am looking at a Hilborn 2 3/16 unit would this be big enough , the engine should be capable of about 670 horsepower,  thanking you in advance

Spud Miller:

 Should work great!

kiwikid:
Thanks Spud  is there mush advantage in using say a,  14 nozzle  ànd waterman  sprint pump  cheers

Spud Miller:

 Sprint pumps are good stuff and for that engine size, a #12 or a #14 Hilborn nozzle sounds about right.

JrFuel Hayden:
We run our all iron 403 ci SBC, raised runner heads on pure alky using #14 nozzles, running 7.0's and 188 -189mph. However when we raced Salt Lake City, with the track at 4400', and DA at 6500 to 7000', we put #12 nozzles in her, added 4° of timing and a looser converter. Of course we have found the nozzle sizes will depend on the fuel pressure we are planning on running. Don Enriquez runs a low pressure set-up , like 50 to 60#, using #18 nozzles, and a -1 pump.
