I want to install a oil cooler with fan, but I havent found anything with 3/4 to 1 inch line size, needed for minimum of 700hp and looking for maximum flow

Rippy, check out Earl's

All the way up to -16 lines, then add a fan.

Check out the DB-30613 Enduro oil cooler from Fluidyne. It is big and works great.

Oil Cooler, 15 in. x 15 in. x 9 in. Cooler, 11 in. Fan, 1/2 NPT Female, Kit

thanks, its a great start, I was pre-runing from walters camp to quartsite and was running at speeds of 100 to 130 most of the time and the temps were a little high, I would like to keep all the lines at lease 3/4" to match the outlets on the oil tank, 1/2" might increase pressure but cause restrictions of oil flow which could cause some other probs

Crowdog this seams to be a great application, I did a little bit more, this part # is actually for the 3/4" size I'm going to give them a call monday. Thanks James

Keep in mind if you can't find what you want, it can always be modified to fit. You do know a guy who can weld aluminum.

Fluidyne makes two coolers like this, be sure to get the right one for your aplication.

If you asked for the best it is Fluidyne, Get ready for the price.

Kartek carry's this same one, but PWR brand for alot less $$. Call Mike O and tell him to have whatever size fittings you need.

...........Although I didnt use mine for engine oil, it kept my th400 with a 3500 stall cool. here is a pic for reference.

If it is made by PWR it is not the same as Fluidyne, It might look the same but it is really not.

Whats the differance? They do the same thing. Why pay more if you dont have to? I run PWR stuff with no problems.
