Hey guys, what would you recommend for my next mod? I have an 06 STS-V, 39K miles, with a full intake and tune. What would be the next logical performance mod? Not looking to spend a whole lot or get crazy with her. TimmyC upper 10% OD pulley? I think the lower is a bit more than id like to invest in right now. Let me know what you guys think.

It's an upper pulley. Injectors will be maxed out but might not need to be changed. I've done it both ways, just depends on the car. A heat exchanger is a good supporting mood for the 2.4

my thoughts on pump are this, but tell me if Im wrong. For a car with an upper, the slower the gpm of the pump, the longer time for the fluid to cool in the TC exchanger, and therefore the more hest can be absorbed. Am I nuts? Wouldnt a stronger pump defeat the purpose?

Upper pulley or lower, your spinnig the sc faster.pump the coolant slow and more time to absorb heat, pump faster and absorb less heat, plus you have about double the coolant and better heat exchanger to defeat the little heat that it incured threw the ic.i think bigger heat exchanger, bigger pump and double the coolant is better.bigger is better.lol
