I am running my flowmached 22 lbhr injectors on my Mini-Ram motor (see sig. bellow) and was wondering what you thought for my next size of injectors? I was thinking 24 or 30 lbhr injectors. Or do you think Ill be ok for now with what I have?

------------------
Convertible, L98, Mini-ram, ZZ9 cam, Comp Cams 1.6/1.52 steel roller rockers, Trick Flow 23* heads, K&N's with chopped airboxes, March underdive pulleys, Edelbrock ceramic coated TES, Flowmaster cat-back exhaust, Dynomax high flow converter, Accel box & coil, Fastchips custom chip, MAC sub frame connecters, Lakewood LCA & Adj. Panhard rod, SLP 2500 stall, 3.23 rear gears, white face gagues, and NOS!

 

At the very least ... SVO 24lb injectors (which are really 26lb/hr injectors according to GM standards). With the SVO 24's I was getting around a 90% Duty Cycle at 6500RPMs. I swapped to 30's and got around 77% Duty Cycles at 6500RPMs. Either injector will work fine ... the 30s are better from a DC standpoint and will give you room for future modifications. However, neither of these choices will work well (especially the 30s!!!!) unless you have a chip that matches (IMHO).

I run 30s and they idle exactly like my stock 22's did. But, I program my own PROMs and did the necessary changes to allow this.

Smart *** !

 

Thanks for the reply TRAXION. I guess Ill get 30#. I figure running SVO 24# at 90% all the time cant be good. And yea, Ill get the chip done.

 

You wouldn't be running them that way ALL the time. Only at 6500rpms. That's why I indicated that the 24lb SVOs would be fine
