![]() Then I would just cut off the existing shroud behind the fan. Personally, I would just make a small bracket to attach to the radiator that would cover the top of the fan, unless this is an open front end car. I don't see it causing an overheating issue, but it probably won't help, should one occur either. The air turbulence was an interesting idea, how this fan/shroud would effect the air turbulence is pretty unknown.Īt least this shroud covers the fan, by the rules. With the fan in the square section of the shroud, and almost 5" forward of the most efficient location, the fan will provide little air flow, with the exception of the area directly in front of it, provided the fan is not very far away from the radiator. Inline grease exhaust fans should be installed near the end of the duct run to reduce sound at the hood. The other concern is how efficiently the fan can pull the air through the radiator, the reason the fan is centered in the shroud opening is because that is the most efficient position for the fan to be in to be able to create the most air flow. With so much of the radiator exposed outside of the shroud on both sides, that would be a non-issue in this case. One of the concerns about sustained higher vehicle speed is that the fan can actually restrict the air flow through the radiator because the fan acts like a big disc blocking the air flow, especially if the fan is centered in the shroud. On a circle track car both of those conditions are pretty limited. The idea of a fan and shroud is to pull more air through the radiator at low vehicle movement, or low motor rpm. 31vicky, I don't believe the fan in your application will do much good, and really, it probably doesn't have to.
