The 60# mototrons are the only big'uns I'd get...

None of the other big injectors, even the 50#ers, are as stable at low Pulsewidth for an engine with a small per-cylinder displacement like ours.

these links make it look like the next step down is 36lb <edited>

iirc, johnny bravo had a set of 55lb siemens that he said were wide-cone spray. not sure where he got them, though. neither of these links provide much in terms of product details or Siemens part #'s.

<edit> re-read our e-mail exchange and he said better spray & atomization than green-tops. didn't say more specifics on the spray pattern </edit>

that's what MIHNEA suggested too

but with my home brew don't you think they'll run way too rich even @ 3 bar ?
i still want to switch the maf to the rs4 piece.. that is 83mm versus the 85mm i have now and the cf's are going up too high .
man it would be nice to have a small gtg and talk about this over a beer and some food
