  • AnswerQ: 1.1?  jakerWRX 3 years ago

    is this a good pressure for a 09 stock sit?


    • A: A normally recommended combination for more thermal capacity is a 1.1 bar cap on the top and a 1.3 on the bottom.

  • AnswerQ: which cap for daily driving?  rotten rod 4 years ago

    What cap should I get with a new Koyo racing radiator? I don't race, just regular driving, just want good performance and don't know what pressure cap to use... Thanks


    • A: Depends on your ambient temperatures, however a good combo if you need more thermal capacity is to do a 1.1 on the top and 1.3 the bottom.
