Not doubting you as I have heard it before, but how do we know how much more effiecient it is? Are there any specs that show this or is is just assumed? I mean my FRPP all Aluminum Radiator is much better than what I had in there and it seems to be doing a great job, maybe even too cool. The termostat hardly gets a chance to open as it is.

 

They stopped making them about 4 years ago, so forums and ebay for a used one are your only hope.

But you could also look into the ford racing radiator, not sure if it is still made, but it was close to the same specs as the saleen, just not a bypass radiator.

 

heres the Ford Racing Radiator, I bought mine and took it to a performance shop and as azmidget91 I had them modify it to have a bypass, cost me around $800
