I have the radiator already made . It is a budget buster for this project at 425.00 dollars. But needed for a nitrous bike. It has a large resivour on each side and a thick core. The Intercooler will mount below it.and the oil cooler will be behind the radiators upper edge..I also use engine ice as coolant. Last run with nitrous. I got a 209 deg F as a high temp. That dose not even turn on the fan.
The nice thing about racing is I don't need an exhaust . About eight inch from the turbo will do.
All of this cost money and is not part of a 1000 dollar turbo project.
