I am going to make a custom radiator for a turbo ef roadrace car and heat is a big issue.. I would realy like a good efficient radiator that is as large as possible.. A custom size PWR core was shipped to me in Sweden for about $400 and I have a brand new griffin v8 radiator that I can cut up to the right size and weld new aluminium tanks to it for about $300. the pwr and griffin were the same thickness.

I am hessitating because the griffin radiator is a"cheap" radiator and I do not know if it is s good quality high efficient radiator core.. And the pwr one takes about 3 weeks to get here and time is also an issue..

Anyone with real experiance?

I ask here because I think that the most knolage hangs out here..

 

I don't know your setup but I think tony has a great setup going on with his radistor kit...check it out

Are you running a turbo blanket?

I have looked in to that but I already have an half style pwr and in a EF car it is no way that tonys thing will fit.

I am just looking for input on different radiator cores..

 

Im not too sure on a roadrace car since you posted in drag racing....

But I think the fan has a lot more to do with it then the actual core... just from my experience.. but I could be wrong

 

full-race has a ef radiator that is half size thats made for the ef. i use it in my ef4door hi- comp engine in the arizona blazing heat with a 12 inch electric fan it does the job just fine in rush hour traffic and when raced

 

I went with the griffin rad.. It look half deacent anyway.. On a high power road race car it is not a matter of IF you will have heat problems.. The question is how mutch.. I want to maximise it as mutch as I can so I already got the best flowing fans I could get and wanted to optimize the efficiancy of the radiator as mch as I can.. Thats whay I posted..

The setup is a fully built b16 84mm gt35r making 587hp on a very conservative engine dyno and maxed out the turbo at 30 psi reving to 10500 in a civic ef..

It will get a modified pwr half rad in the front and a second custom one in series in the rear bumper with a tunnel in front of it instead of the stock spare tire compartment. 1 fan on the front rad and 2 in the rear rad. The electrical waterpump has electrical adjustable thermostat with adjustable flow.

The stock waterpump will be removed and the water from the rads will be entering the engine in each end of the head and exit at the stock waterpump and in the place were you mont a electrical engine heater below the header on the passenger side. The flow in will be matched at each side and also between the exits..
