Hey guys,

So the plan is to put in the hydra and 700cc injectors this weekend.  Needless to say I'm nervous.

Question though.  With all of the extra power that will come with the hydra, there's going to be more heat.  Will the stock radiator and fans be able to keep up with the extra heat from the hydra?  I plan to autocross and track the car in the future.  I plan to upgrade the radiator and fans as well but not for a bit.

Thanks guys!

In a warm climate, probably not.  I'd upgrade the rad and/or fans before you hit the track.

The crossflow rad isn't sexy like wheels or a new turbo, but it's one of my two or three favorite mods because it means I basically never worry about overheating on the street or autoxing.  For heavy track use I'd probably add fans or ducting, but short of that, its performance and peace of mind are worth every penny.

What do you think about this radiator?  I would go with FMs but of course it's ridiculously expensive.

Many discussions on here about how Mishimoto is  no better, and likely worse, than stock.

The track guys will chime in, but some of the thicker Koyo rads are a better bet.  But I'd say you should save up and get the good stuff to go with all the good stuff you're about to install.

Never buy the Mishimoto stuff.  The best thing they have is their marketing!!

This is one place you don't want to cheap out.  I bought a Koyo unit before the FM unit existed.  It was no better than stock.  I added the FM fans and it made a difference but I truly miss having been able to get the FM Crossflow unit.  If my MSM was still seeing track use I'd be adding the FM radiator.

How much track experience do you have?  If you are just starting out, you will probably be ok with the OEM radiator for a little while.  The more you start pushing the car, the more issues you will run into.  If you are in Florida, the air temps will not be on your side.  My car is driven in anger on the track by both my wife and me, so it sees a lot of track miles.  The car is pushed very hard and I have an FM intake, DP, exhaust along with the crossflow radiator, stage II fans and oil cooler.  I still occasionally run into over heating issues in June at our home track in Savannah, GA.  I've just ducted the radiator, so hopefully I will have finally overcome the overheating issues.

If you do notice the car running hot, you can turn the heat on full blast and it will cool things down....except you will have a heat stroke.   Smiley

BTW, if you still have the original OEM radiator your probably on borrowed time anyway so it might be smart to suck it up and get all new stuff before you have a failure.

Having the Hydra for a few years in the Phoenix summer I can tell you that for commuting/canyon carving our rad is just fine.
So I would have no problems telling you that you can stay stock until your first track event.
