its hard to say. i dont really drive it that much because it is winter. but i do know that when it is about 40 or below i hits 100. and if i rag on it i think it hits around 150 that is flooring it all the time, pealing out, racing. just about everything you could do.

when i first installed it it was about 70ish out and it was just above 100, 125 maybe. i have never seen it hit 200 when i rag on it.

 

looks like a clean install.

 

It wasn't the biggest, just the one that alot of people recommended, plus it was the only one that came with extra tubing, brackets, misc hardware

I might try the 11x11" if this one doesn't cool any better than the stock one.

that 11x11 looks good, especially since it dosent use the barb hose fitting like the one i and u have... and has the npt fittings

03 have yo noticed it leaking tiny bits of oil? mine leaks just a small amounts, not enough to drip but just soak up the lines and hoses.. i hate that..
