Which would you perfer??? Thanks

 

Water Injection. I've heard the J&S retards leading so much that it causes negative split.

I'd rather just set everything up use the water injection, know its all working the way it needs to be and not have to worry about the J&S messing with my timing

I'm with SPO...after reading some specs JS&, I'm suprised it hasn't caused more motor failures due to the potential of creating a negative split condition by only retarding leading. Maybe it has, but everyone was looking for "some other reason" and never suspected the J&S.

water injection.
it has more advantages over the J@S
it's a HP mod as well ar reliability and the cleaner internals are nice too.

 

Whats the difficulty from 1-10 on installing Water Injection?

 

So which is the water injection system of choice????
Price?
Where to purchase?

Etc...


Thanks

 

The PFC doesn't respond to knock sensing so if you install a J&S it may retard such that you'll have negative splits ...

I decided that water injection with a water level sensor to switch from 14lbs boost to 12 lbs boost when water tank is empty suited me better... BTW, the datalogit box has a connection that when grounded, switches your boost level to a preset level. My cost was $500 but haven't installed b/c I need another reman, a paint job, JimLab bushing, HID headlights etc...

 

This is the water injection setup I just finished installing in my car, except I used the tank from a Spearco kit. I think the pump was much over-done but even so the whole thing can be built for about $150. I would say it is about a 5 on the 1-10 scale. I spent 3-4 hours on the whole thing.

 

I would rather go with the water injection too.

But just to defend the J&S.....yes, there is the potential for a negative split, but it would only be the fault of the tuner/user. If you know that the total adjustment for the J&S would be, for example, 8 degrees, then a GOOD tuner would analyze the maps and make sure there was always a 9 or 10 deg split. Therefore, even if the J&S did a max retard or 8deg, there would still be at least a 1 or 2 deg split.

Just what I've been told
