Re: RnD Fabrication 1973-1987 Chevrolet & GMC C10 / C20 / Suburban Radiators!

HP ratings depend on type of HP (n/a or supercharged / turbo / nitrous), where you live, and what fan set up you have. Generally, with our basic level of fans they are good to around 450hp. Then with our upgraded fans, good to around 550. Above that, we have extreme duty that run upwards of 1,000hp. Once you go above 550, we recommend using Evans Waterless Coolant as well, which raises the level of HP you can run before overheating.
