I've found a more then reasonable and what looks like a well constructed double pass aluminum radiator. Proven technology or? The seller claims it's good for up to 600hp.

 

Benefits? Anyone? lol

 

Of a two-pass? More efficient than a single pass type. Stock is two-pass so anything by just being two-pass alone doesn't say much. Material, overall size, core size, number of rows, etc determine effciency. Need more info.

"2 row radiator with 1-inch tubes and a positive tube to fin connection, which allows for superior heat dissipation. This radiator is equivalent to a 5 row copper/brass radiator"

The core size is the same as my stock, they just move the tanks (stamped alum.) to the sides as opposed to the top and bottom. And it's 3" thick. Helpful? Thanks!

 

Double pass is generally more efficient, it allows more temp drop since the coolant stay in the radiator longer. So who makes this radiator?

 

I have been running a custom designed(by me) double pass alum radiator. has worked great, and when I had the radiator shop(stock car race shop in North Carolina) built it they said it would work on a race car with 600hp. who is selling the radiator and for how much?

 

I think it's Benny.

 

Benny? Dunno Benny! $300 USD to your door though. Someone told me that you need 16x the pressure to run a double pass efficiently (over single pass) but stock is double pass so I'm not worried about that, and the tubes are 1" so it has to cool better. Still perplexed...

 

no Benny from Realride.
here is a link that show pic of the car and engine.

this radiator works great but it does not mount in the stock location. it has a slightly larger core than the stock unit. a couple holes need to be drilled on the right side radiator support. works great on our race cars, but may need some work to fit a totally stock car.

 

Can you give dimensions of this radiator? (LxWxH)

 

Radiator Overall Dimensions:

27” Wide
19 ½” Tall
3” Tank Thickness


Radiator Core Dimensions:

22 3/8” Wide
18” Tall
2 ¼” Core Thickness

 

Thanks,
The width is perfect for me, but the height is about 2" too tall

 

I'll keep my eyes peeled for ya. Its great for me (I think) because it lops off 2 inches in height due ot the tanks being moved. Run a nice 14 inch SPAL puller fan and it should be enough, or dual 10's maybe... hmmm dunno

 

Right now I run a VW Scirocco radiator that is a double pass (13 x 21" I think). It works OK and keeps temps under 180 on the street while moving and with fan on manual. I would like a little more for running track days. Last time I was running at 200-205F on a 95deg day. Then again that was before I made some ducting.... but a larger thicker core would be nice.

Anyhow, I use the Summit Racing metal blade 14" fan rated at 2300 cfm and it does a real good job. Best part is it only cost $75.

 

Do you have a part number for that rad Midget?

 

Sorry, I was asleep at the wheel....

Rad is from Summit (Jegs has one too)
Summit part # SUM-380648, $109

Fan is from Summit.
Summit 14" 2300 cfm electric fan part # SUM-320714, $74.99

This is the lightest radiator I have seen, and it has worked well for me even with little to no ducting (I know its a big no-no....). The fan switch is nice (use a relay), and the pressure cap is rated at 13psi which is the same as the stock cap. Only thing I dont like is that the top row of fins is not caped off and is exposed. I took a piece of 1/8" thick x 2" wide strip of aluminum and RTV'ed it over the top between the tanks to make it look finished and keep the fins from geting damaged during normal work around the rad.

 

Cool ,thanks so much for the info! I was thinking about that rad cause it looked realy light, but I wasnt sure if it would work for my car.
