Single Cooling W/ Riva Red Pipe and ADA Head

[Th3 VVay]

Hey all, I'm finishing up a 701 swap in my SN superjet and the only thing left to do is hook up the waterlines. I've been having trouble finding information on how to route the waterlines. There's a lot of information on the B pipe obviously, but I couldn't find anything about using an ADA head with the Riva Red pipe and single cooling. Water temps around me rarely get above 80 so I plan to stick with single unless it seems to be running hot. From what I've tried to gather, I think it needs to go like this (hopefully someone can chime in and confirm) :

1) From the firewall (pump) to the bottom of the manifold.
2) Out of the head to the bottom of the head pipe. (Should I T the two fittings on the head together or block the one at the front of the head and only use the fitting from the back of the head?)
3) Out of the top of the head pipe to the pisser with a T running to the stinger.

1) From the firewall (pump) to the bottom of the manifold.
-Correct

2) Out of the head to the bottom of the head pipe. (Should I T the two fittings on the head together or block the one at the front of the head and only use the fitting from the back of the head?)
- Rear of the head to the bottom of the head pipe. Do not T the two head fittings together. The front head outlet directly to pisser.

3) Out of the top of the head pipe to the pisser with a T running to the stinger.
-Correct

I appreciate the feedback. So if I understand correctly, your saying I need 2 pissers? One from the T between the top of the head pipe and the stinger and one from the front fitting of the head?

I ask because in another thread for the B pipe, it was said that with single cooling there should only be one pisser. There's just so many threads and nearly all of them have different instructions. Again this is for a Riva Red (which I assume should route the same) but maybe not. Can anyone else confirm the above information? Thanks.

I run single cooling on my Blaster with two pissers with no issues at all. You will find out that people run their water lines many different ways. But for simplicity sake and the in order to visually see you have flow through the motor and pipe this is the ideal way (IMO) to run the lines. IF you have a cooling issue with the pipe you could always restrict the line coming off the top of your head with an old needle and seat drilled out to 1/8".

Always 2 pissers, one strait from head and one from pipe.

Thanks for the info, I ordered an additional pisser today and I'll plumb straight from the front fitting of the head. How do you know if you need to restrict a line? Is that only if it seems to be running too cool (I don't think I'll have this problem with single cooling)? Whats the best way to determine it is running at the proper temperature? I have a pretty good idea of how warm the water felt coming out of the pisser on the 650, so just shoot for that or is there a more scientific way?

Temp gun the cylinder and pipe to fine tune temps.

what are ideal cylinder temps? (cast Cylinder)
(billet cylinder)?

Sorry to wake a dead thread...
I am installing the same set up. What should I do with my top manifold fitting? (I only saw bottom manifold fitting listed above)

1)From the firewall (pump) to the bottom of the manifold.

Options

1a) Add a T fitting and tie from the pump into both bottom and top fittings.
Or
1b) I do what Mike suggested then plug the top manifold fitting that was never listed?

I am leaning towards option 1a... What does everyone else think.
