Those of you who posted issues, expect a PM from a Mishimoto rep. We're trying to find a trend, why some aren't experiencing this and some are.

^only way bending that lip would work is if you had custom rad top mounts.

or drill another set of holes on the rad. mounts so it pulls the radiator closer.

Having owned both, besides this issue, mishimoto is superior in performance. Build quality may lack compared to a fluidyne, helll mine actually lasted through a fire, but the point of a performance radiator is to perform and the fluidyne simply lacks in that category especially for the price.

i find that hard to believe when i know a few people with high horsepower 7ms with fluidyne and they are nothing but happy...i know some one with a 400hp 7m hes been running his for 5 years no problems...good luck hope you guys figuer all this out...

They aren't complaining because all they have to go by most likely is the stock rad's performance. I know, I've owned and used a fluidyne for 2 years under many many conditions. The bottom line is the fluidyne simply does not have the cooling capacity of the Mishimoto. It could not and will not match it, both from personal experience and on paper. My car is potentially 400+whp and daily driven vehicle, so don't bring power into it, not that power output truly matters in most, normal, cases. In no way am I suggesting its a bad radiator, but for the money, it simply does not perform like it should.

Yes, and the mishimoto is obviously too large and that's where the cooling capacity comes from...

As for a trend, early square mounts vs the later fluid filled ones comes to mind...

Well since Motor mounts are a potential issue/cause of the problem, I will post up that my 92 has 98 mk4 mounts on it that are only a year old. The car has seen a few track days since the rad install along with a boat load of hard street driving without issue. Tomorrow I will measure my fan blade to rad core clearance and post it up.

Thanks, I know mine was very small. Even cut back I can't fit my finger tip in between that and the end tank. Be sure to get the distance to the end tank and not necessarily just the core as its the end tank causing the issue.

87, original mounts, replacement shroud.

The shroud took a hit and has a couple scrape marks inside. Not like A.Jays pictures, more like it's just been rubbing and has a couple cracks.

^good to know! Thanks! I've been working with a Mishimoto rep directly to aid in fixing this issue. In the mean time, keep a close on it and I would advise against long road trips so you don't get stuck anywhere.

Ended up looking a bit closer. The hit was from the shroud being loose where the upper driver side shroud mounting tab split and cracked. With the shroud properly held back I have 1/2"+ of clearance.

Mishimoto with custom mounts and engine on solid mounts, one fan blade sheared off about half way up and rad looked like this.

Going to see if it can be repaired, you never know!
If this is hapening as regular as it appears perhaps Mishimoto should take some form of responsibility!

Maybe it was cracked because it got hit....

They are taking full responsibility so far, they are coordinating meetings to redesign. I have been in close contact with them and feeding them suggestions. Thanks for the post. This eliminates the idea that mounts are the issue, seems to be primarily fan flex.

Gotta admire that sort of service it's rare these days!
