That's a beatifull setup
. I have one question. Would'nt the accumulators and solenoids/HSVs work better the nearer they are to the jets. My reasoning is, that if the accumulator is all the way in the trunk, ther would be quite some lag between when the engine makes boost (or reaches the desired trigger point) and when the water starts so spray under the desired pressure. I can't imagine several feet of hose between the trunk and the engine helping very much.
