Some issues with the alcohol injection

fst100 · 07-10-2006

i just installed my custom alcohol kit. shurflo pump 8000series w/100psi. ID hose size is 1/4" with boost switch set to turn on at 2.6# and using a m3 nozzle. i still get blips of <1* of KR when i either gradually step into the throttle or nail it fro a roll. aside from the burst of KR due to a possible torque management, i usually get blips of, again <1* of KR. the pressure switch, i know doesnt do anything in increasing the psi flow of the w/w fluid, but just to let you know, its turned clockwise/increased quite a bit. i have both an m4 and m5 with me, should i install the m4 and see how that goes in killing the blips of KR or is that overkill? TIA

PS-should i regap my plugs and see if that helps? if so should i decrease the gap to, for example, 0.045?

mods of concern: 3.4"MPS, 3"DP, 180* T-stat, DHP PCM with stock timing, AL104@0.050, Ported Exhaust manifolds.

also, i have the shurflo pump on its side rather upright, is that ok? its resting where the pcm use to sit. will that affect slow the pump at all?

The pump can be mounted in pretty much any position. You might want to consider getting a mini AFC to tune with as well.

sorry, i forgot to add that lol. i do have an afc2.2 and an LS1M. there's too many bolt-on mods i did. basically, i completed almost every bolt-on mod available w/o going into the internals, like rockers.

2.6# is kinda low for a hobs setup to come on at. Most people with a progressive kit can get it to turn on that low only because the pump is @ a 15% duty cycle. I would have a hobbs setup "on/off" come on around no lower than 7 psi. I would also try alittle larger nozzle.
