97 XPL With Spec 1
I am working on setting up a spec 1 on an 97xpl and I have no experience setting up the water injection on a XPL. With my 96xp I didn't run a water injection fitting on the stinger as the and the water met. The waterbox was jetted with a 120.
Now being the XPL has a 2 foot piece between the pipe and the waterbox water needs to be injected at the coupler were the spec 1 meets the 2 foot pipe to the waterbox to keep temps down.
Now I know that you will not want to inject to much water at this point because to much water can create to much back pressure which in turn will create heat.
So my question is what water jetting should I run at the stinger and the waterbox on a spec 1 on a 97xpl?

ok they didn't make a 97 XPL
is it a 97 with the 785 or a 98 with the 951..

Robert you should call BT on this.
I can tell you the 96 has a coupler that will melt just like the 97, the 97 just has one more... From what I remember the midpipe needs to be jetted larger because of the heavier hull. No need in jetting the stinger though, at least not for coupler melting considerations.

on my old 951 setup i taped the stinger and had a three way silinod with a microtouch controler. at high RPM it would "shut off" water to the upper injector and "turn on" the stinger. if you dry the top injector without adding water at the stinger you will definatly melt those couplers and that 2 foot pipe can get hot enough to melt the tank

BT's in the house.
Yes, that long tube changes the setup a little. I ran a 120 jet in the water box with a jetworks control valve and a 60 jet at the stinger. I ran two inline water filters to ensure that small 60 jet did not get plugged up with debris.
You also will probably need a little bigger jet in the midsection to help build a little more torque for the larger `97XP hull. My setup used a 100-110 jet in the mid depending on weather.

Should he use a 120 in the head pipe?
Hey, Robert I meant to tell you I let my son take the 96 to the
lake with friends by himself. First time for everything. I figure
it is safer than 2 $8500 RXPs going.
