I have a water to air set up. I bought a bigger heat exchanger for like $90.00. It is the thickness like my 4 core radiator in my 69 coupe. Seems like it will add more fluid capacity and cool more efficiently due to its design compared to the stock little Roush cooler. I am not changing anything else other than building my own oil catcher keeping the same pulley, etc. I live in Dallas Texas so in the summers it gets hot. I am looking for a more stable power band like 2005REDfire6 was talking about. Thanks for your reply's.

No tune is required. The MAF has the ability to make minor changes to the tune, this allows it to adjust for the different densities of air. *i.e. summer and winter ambient temps*

Like most have said, NO, you are good to go!

It is used but in perfect shape. It is like the $400 unit from Steeda. I will post pictures when I get home tonight. I also am doing the oil separator mod as well.

Congrats on the upgrades, be sure to post pictures of the heat exchanger! My vortech setup currently utilizes a Roush heat exchanger. I have a secondary Roush heat exchanger as well that I purchased used since I was having issues with my current one leaking but it is fine now. Looking to upgrade to a GT500 AFCO unit soon!
