Why - b/c rads and/or coolant capacity are vastly diff b/w i.e. 997.1S and 997.1 GT3? They're not Burg Boxster - 8 years ago |

It's just YOUR opinion. Don't try and give some BS answer about finer versus fluffier trash and opening then when debunked pivot elsewhere. We're talking loose mesh (85%+ open) and condensers and rads. Trade off in airflow/volume w/b minimal and these aren't jet engines...
Rocks, among other items, take out condensers and rads - all. the. time. Rocks being most prevalent and mesh certainly helps prevent them from not only being taken out but also accumulation of debris - also affecting their efficiency. One needs to continue being smart about vehicle maintenance regardless of mesh or not. Dollars to donuts I bet servicing for a car owned by individual A would constant w/ or w/o. Actually, if anything, w/ mesh might lead to more frequent maintenance. Readily seeing what gathers in area (and stopped by mesh ) might trigger subconsciously how much more gets by and therefore needs cleaned. I can tell you (all things considered) over equal mileage/conditions, the "stuff" b/w my condenser/rad behind mesh has been substantially less than w/o. And, knock wood, I haven't lost another condenser in this P-car since.
Now, condenser I lost in my DD SUV due to a perfect strike b/w fins from a mammoth-sized carpenter bee (true)... Yeah, I certainly chalked that up as bad luck and just moved on...
Not a trick question...Yes / no - rad part #s & coolant capacities are similar b/w examples I sited? Burg Boxster - 8 years ago |
Are coolant capacities and L/R rad p/n same between? GT3 does have center rad - as can 997.1, properly equipped.Quote

On the face of it your claim the cooling systems of the 997.1S and the 997.1 GT3 are not different is just wrong. The two cars have quite different power outputs and if the GT3 had the same cooling capacity at the lesser model it would overheat. The S produces 355hp @ 6600 RPM while the GT3 produces 409hp @ 7600 RPM.
Previously it was your opinion - see above. Regardless, please provide link RE: 986, 987, 981, 997.1/2 and GT3-997.1/2 where no mesh s/b fitted, Thanks.Quote

Further, it is not my opinion regarding that fitting screens to the radiator openings is a bad idea. It is fact. Porsche in at least some of its documentation advises against fitting screens to the radiator openings.
Huh? Trash removal prevents corrosion which would adversely affect cooling efficiency. BUT, per you, prevention only occurs when trash is removed after it's been embedded in condenser & rad but not so by preventing from embedding. In summary, you are saying preventing 'trash' (of course the nice fluffy and/or loose kind - or whatever your argument was originally) from entering said area via mesh does NOT help; it's only when trash is removed after it entered does it prevent corrosion which prevents there from being a problem in cooling. Got it - appreciate your fine clarity.Quote

While many are concerned about a reduction in cooling from the collection of trash in the ducts, this is more imagined that real. Even though my first radiator cleaning removed a considerable amount of trash the engine's cooling wasn't affected either before or after. The real benefit is removing the trash prevents corrosion of the condenser and radiator.
We agree...mostly. If you reduced OPENING by 40%, air flow and cooling capacity could, dependent on operating conditions, be substantially and adversely affected. Please provide link showing said 'chart'. Also, please show some advanced math where my recommended 85%+ open mesh equals reduction in area to 40%? Many thanks.Quote
MarcW
The reduction in surface area from fitting a screen can be substantial. It depends upon the wire size (diameter) and the spacing. There are charts which give the reduction in area and it can be on the order of 40%. If your choice of screen doesn't appear on the chart there is a formula.

As do some older models too... Let's define new v old via MY dates.Quote

While a few newer Porsche models come with screens I'm sure the car's aerodynamics and fan cooling stages and possibly other things are different.
What? Why stop at GT2? Your pivot should be to 918 or 919 since each is oh so similar in architecture to NA Boxster (986/7/981) and 911 (996/7/991) of discussion...Quote
MarcW
At least one Porsche model, the GT2 I think, comes without a driver's side radiator fan. Are you going to remove your car's radiator fan because this one model has it missing?
Awesome - outstanding and extremely insightful. However, you forgot bee I mentioned. How can I avoid those? Please help???Quote
MarcW
My suggestion if you are experiencing damage to either the condenser or radiator from rocks instead of fitting screens you should just avoid following vehicles too close. Not only does this avoid condenser (or radiator) damage it also avoids rock hits to the other parts of the car.
