I am running -10 hose. I had it on there late last year with water pump and radiator up front without issue. Relocating to rear n oh w the issue. Do you think the pump just isn't enough? Or not enough pressure with the -10 lines?
I also had free flow air as I had them spaced down about 2 in from the trunk floor and had some ducting that caught air from underneath the car and directed it up to the tops of the radiators between the trunk floor and the core.
Mezere 55gpm pump is another good option. They offer radiator mount as well as remote mount. The -10 hose has too much friction loss per/ft. -12 at a minimum, double supply/return is available on Mezere pumps and a good option. -16 as stated above is good if single supply/return. I am going to use a two(2) pass dragster radiator with remote pump and expansion/fill tank in the trunk area.
What pump are you using?
I went with a single EWP150, 16an hoses, 1" aluminum piping in the center of the car, aluminum dual pass Scirocco style radiator, Moroso style expansion tank, and the 16an line splits to 2 12an lines in/out at the engine. No run time yet but don't foresee any issues.
Also not sure who has used this but I am running one. It is having issues letting water out into overflow without any pressure. I tried 2 different used radiator caps with no luck. Any ideas?

Has anyone seen any improvements in performance by raising their fuel pressure? I'll be installing one of the new Aeromotive pump in the next week and it has enough pressure/volume capability for me to easily raise the base fuel pressure from 45 to 65-70. I don't figure going higher is a good...
They did the classic bait and switch......kinda. Everyone thought the big news was the new full color digital dash. Well Thursday morning I get a Dealer Tech Bulletin about a new controller. It didn't give a lot of details but I made a bee line for the Haltech booth
WOW!!! They have not released...

I had been running in batch for initial start up and first road trips. it would run somewhat ok but had sync issues as rpms climbed past 2500 rpm...
