Jake, I would appreciate your help and definitely sleep better if you could let me know if my RAT Motor requires an external cooler. I purchased my JPS speedster a year ago with no documentation besides the title. Let me know what it costs to get the build spec's on my motor. I think this is good information I should have and keep with my RAT powered car. I have attached the RAT ID for your review. Any and all help is appreciated!
