single vs. dual cooling f/s porting (magoo)

[Idok]

getting ready to drop in my new magoo/LPW motor:

82mm
165psi
2mm static advance
MSD-E
61x fly
single TLR 48


can I get away with just single cooling (split to either side of ex mani), or do I have to add a second dedicated cooling line????

Single is fine I say.
I think dual cooling comes in handy for supplying cool water under good pressure to the headpipe.

Why would you want to do this? Your ski's already set-up for dual, so I'd run it. BTW---did you get my pump out of the attic yet? :sneaky:

the mag was set up for dual, but the stock pump im running is just set for single (i think)......

if I need dual cooling, not a big deal...but I still have to do a motor install and redo all the lines and such for this weekend....just didnt want to have to do something else if it wasnt needed...

however, I did install the cooling lines with enough slack to do whatever I wanted with them, so If this weekend she seems to be running hot, not a big deal..then I can change out the pump




i also have a concord to install, but want to try this motor first with the same prop so as to really get a feel for the differnce the motor makes......then will do the prop (and cooling, if needed) next week!

single cooling is fine. Do you have a b-pipe?

 

[Idok]

yup...Bmod..

I was just down there in FL two weeks ago riding on Lake Tarpon and was sweating even when in the water. With the higher FL water temperatures, I would suggest dual cooling with a couple restrictors, or better yet, a Jetworks flow control valve. I think in the summer, in FL, you will see a performance difference with the dual cooling. Perhaps it's not as important up north.

This kind of info should be part of the the package. My builder always has very specific specs for cooling, jetting, pump/prop,etc. I'd call Paul.

i think you COULD run that motor all day long with single cooling.

but you know what you SHOULD do here.

dual.

Agreed. How hard is it to tap the pump and install a brass fitting? (Spoken like a true plumber.):sneaky:
I don't like to argue with the 'Dok---I saw how he jumped on Slutty in the plug thread. :haha:

 

[SUPERTUNE]

Drill and tap the bottom of 'B' pipe manifold with 2 90/ fittings and then run short waterlines back to the firewall with a 'T' fitting for your single cooling line for now, That way when you do plumb for dual cooling that part is already done. Run 2 outlets on the head and 'T' them back together for a single outlet to the pipe 'in' fitting...this way you cool both cylinders very even and helps the jetting of both cylinder the same with a single line set-up.

Did you ever see my melted piston from sucking up shells?:woot: With dual lines if you suck up a piece of coquina in one line you can see the difference & still be able to ride back normally...:cool2:

Also, when I do a long tailstand in the summer & the water gets on your sunburn it's uncomfortably warm :bigeyes: even with dual cooling.

What you are suggesting would be TWICE as much work as Idok is willing to do right now. :biggrin:

He has a manifold that is already drilled and tapped. He also has a MAG pump in his ATTIC that is setup for dual cooling. He wants to run a stock pump that is not setup for dual cooling---all he needs to do is ONE tap. :banghead:

To the best of my knowledge, the motor is out of the ski allowing for this job to be EVEN EASIER if he'd flip the hull over. at:


On a threadjack note---Chucky, I have only talked to you on the phone once awhile back, probably don't remember me---I have Derek Stein's old Wamilton ski with one of your INCREDIBLE 5mm stroker motors in it and I just wanted to say, "Thank You!!!! You Rock!!!" :biggthumpup: :Banane01:

I always suggest duel cooling on ported motors, just for insurance sake. But espically so in Fla.
Please make sure you do the duel cooling!:smile:

Scott's gonna' love this thread when he gets to work in the morning...
