have someone install the spearco water intercooler kit?
What temp read?

 

As I understand it, that application is more suited for a drag car. For a road car, you are looking at problems with heat soak. I am sure others will chime in with more/better info.

 

Because it is so small and didnt need relocation of battery and bumper cut and long pipes and many more who fmic need I think that is more easy to install this water intercooling with electric water pump and small radiator from morcycle for example or if you have change the stock fd radiator with new like koyo you can use the stock radiator for cooling the ic.
I have hear something about 25 c and that is very very good temp.

 

my buddy has an Air to Water system on his Super Charged Porche 928. He is putting down 620Rwhp. It is a street car only. He has great luck with the system and has low intake temps too. I will have to check to see what exactly. I believe its only a couple of degrees above ambient.

 

That is great news thanks ecarver2
Also I see on ebay that the core cost only 180$ and 90% of rx7 owner have the stock radiator abandoned like me.
So We need only water pump who cost about 90$.
If with total cost 200-300$ we can have very low intake temp then I think that worth the test.

 

one big advantage the WTA's have is the prevent heat soak. the side mounts heat soak like ******!!
