A customer at my uncles shop I work at was torn between the Mishimoto and Fluidyne radiators, so we ordered both and decided to write up a comparison for everyone.
These are for the 94-95 and 97 stangs, although I'm sure the rest are the same. We looked at 3 areas - the support plate, the shock resistance, and the radiator core. This was meant to be non-objective side-by-side comparison.
The Fluidyne:
The Mishimoto:
1: Support plate
The Fluidyne's support plate was 0.2mm in thickness, and the Mishimotos was 2.0mm (measured with a micrometer)
The Fluidyne also had no welding in the support plate, while the Mishimoto's was strongly welded.
The Mishimoto radiator plate has two layers, one is the support plate and the other is the side plate. The Mishimoto unit is much stronger.
2: Shock resistance
The Fluidyne has a hollow tube design, and the Mishimoto is a solid tube
3: The core
Mishimoto has a three row core as opposed to the Fluidyne's two row, enforcing the shock resistance of the Mishi even more.
Our conclusion:
Based on these factors in the visual side-by-side comparison, the Mishimoto appears to be the stronger unit and the better choice. From what I understand, Mishimoto used to have a two-row design, but changed it to the three row because the two-rows kept breaking. Fluidyne's were having the same problem, but clearly they have not yet switched designs to the more resistant three row.
