2.4 injectors.

2.4 injectors.
has anyone had any experience using larger injectors on a 2.4?
from what i understand the stock ones have trouble keeping up at high RPM... so i was thinking a set of stock SS/SC injectors may just do the trick... any thoughts?

Go to: http://www.rceng.com/technical.htm and do the math. I trust Russ; I've raced with his components back in the 70's. He definately knows his stuff.
Our 24lb injectors are at 80%dc for the 2.2l, at about 90%dc for the 2.4l stock.
So, yes, the 2.4l could definately use bigger injectors when modifications approach the 195-200hp level. The 34lb injectors should be good for 230-240 hp n/a (less for a F/I setup.) I don't know what Hahn is running, but I'd suspect 45lb or so.

The problem with the lean code is MAF placement / contamination - more air is getting into the engine than the MAF is sensing. A good tune, richening up the a/f ratio at low throttle applications will solve this problem easily.
