Engine overheating! HELP!!!!
I have a HPI RS4 18SS with a custom cold air intake with a RB Inovations cone filter and a Silver Bullet TSAIS custom exhaust. I'm running a medium plug with 10% nitro.
After about 3-5 minutes of run time, my thermal fail safe (set at 260) Turns on. I tested with hand held thermo, both temps the same.
I tried richening up the mix, got a good blue smoke trail, but still hits 260-280 degrees. I also made sure I had good air flow over head, I cut holes in front and back windows and I removed the grill.
I ran out of ideas please help!!
