comon guys!! i been using EVANS since 1989, in my CAMARO, In my V-12 JAGUAR, and since 1998 in my RX7 T11, and now in my FD. Do you know it was developed for BLACKHAWK helicoptors, cant be all that bad, you wouldnt put WATER in one would you!! let me think here,, ETHYLENE GLYCOL was developed in 1943 for that old tank called P-51 MUSTANG , nice old plane, but ancient by todays standards. so why would anyone not use a modern product yesterday is gone forever!!!!!! and it would not surprise me if ther isnt a better coolant out there by now! ( Im not proud of this statment) THANK the GODS for WAR!

Well, its not on themarket as yet because the equipment to make this is super expensive.

Ran the hill climb last weekend and my cooling system worked great with NPG+.
It was ~90 deg F out and the hill has 1,300 ft elevation change over its 2.2 miles, lots of tight corners.
On my 2nd and 3rd runs up the coolant temps rose to ~1/3rd of gauge (S4 TII) which my Haltech says is ~95 to 100C, oil temps peaked at 100C and EGTs at 800C.
27"x19" Griffin 2 row radiator, NPG+, front mounted stock TII oil cooler and horizontal mount IC with its own inlet duct. 11.5:1 AF under .5 bar boost, 11:1 at 1 bar boost and 10.8:1 after 6,000rpm.

NPG R should be alright.

7 LB. rad cap
HEY! Glassman ,where can I get 7 PSI radiator caps that will fit the Mazda RX7 , called EVANS they do not supply such. I do it rather crudely by torching the spring and they always vary in pressure, be nice to get hold of an adjustable cap. set it up on a cap test unit ,then set it to maybe 5-7 psi.. thx RON

I just called evans to order a 7psi cap, and the tech support told me that on an rx7 i should be running a stock 13psi cap (ast). Has anyone else run into this? Now i'm really confused..... lol

you should be fine with the 7 psi cap. just don't try to run 0 psi. it didn't work for me. Coolant didn't move back and forth between the overflow appropriately.

I have always run the no pressure cap and never have any problems. In fact went to Lime Rock to today, max water temp on PFC, 85C.

I think part of my problem was that in the beginning people were "modding" their stock caps to get 0 psi. I can't recall the exact circumstances because it has been so long, but I think it my case my "modded 0 psi cap" wasn't 100% sealed, so no vacuum was able to be developed when things cooled and the evans didn't move from the overflow back to the radiator. It seems reasonable that with a properly sealed 0 psi cap things should work ok. I guess I should add also YMMV.
