    I replaced both radiators before the 2014 season. Over the course of the year the the water temp kept going up. Started around 106 and now gets up to 117. I use Evans coolant so boiling is not an issue. I did a lot of track days in 2014 (57) and fewer in 2015. I have continued to look at the radiator and see more and more fins closed up from the track debris. Has anyone found a different solution to get better cooling or to make the radiators last longer?

    Options I have thought of:
    1. Just replace with OEM once over 115?
    2. Find a better radiator than OEM. Maybe increase thickness to improve cooling. Space too confined to change length or height
    3. Increased screening to minimize radiator contact with debris that doesn't interfere with air flow

    Thanks Jim. I will give them a call. Have you used them as a direct replacement to the OEM radiator or have you ever tried to customize the radiator to a larger size to improve cooling?

    Its a direct replacement. we used on our 430 challenge car. fit was nice.

    Did not seem to cool much better but better quality for sure.

    Jim,

    What did you see or like that was better quality? Was the price better than OEM?

    When you say they didn't seem to cool better, does that mean that your F430C seems to run at a higher temp than you might expect and you were hoping for an improvement?

    My F430C has always run warmer than I thought it should, but consensus seems to be they run 115-118 when tracked hard. It is not unusual to see it go to 118 and occasionally 120 water even though the oil temp never gets that high. The blue temp warning light and main dash display alert will come on at 123 so 120 is close to max.

    I would be interested in a more robust cooling option too if anyone has had success.

    My 430C ran at 115-117 three weeks ago at a race weekend in Wisconsin. My tech says that's normal

    117 C= 242.6 F
    Pure water would need 10 psi to prevent a boil at 242.
    Adding a mixture of antifreeze would raise boiling point at a lower psi but at the expense of cooling capacity and heat transfer as compared to pure water.

    Another good reason to use Evans waterless coolant in these cars I guess.

    I contacted Scott at Wizard cooling. Very nice guy and very helpful. We discussed the current design and options to improve the design. The OEM radiator and the Wizard replacement has a single row of 1 1/2" tubing in the core. There is no room in the car to increase the width or height. The next step would be to use the next size up core which would have 2 rows of 1" tubing. This would increase the radiator thickness by approx.1". Spoke with Fernando at Competizione who felt like he could modify the space to accommodate the increased thickness. I will post some pictures to show the modifications necessary to fit the radiator in a few weeks.

    Regarding Jim's comment on quality. It sounds like the Wizard radiators are completely Aluminum and welded. I believe the OEM has plastic tanks and fittings and uses epoxy. However, I have not closely inspected my radiator

    Also, found this product which may help protect the radiators as long as it does't cut air flow. Has anyone used a radiator protector?

    My thoughts on the wizard radiator is that the quality is very nice, improvement using all aluminum instead of the plastic tanks on the factory one. the fitment in the car was perfect.

    Although improved, the car did not see to cool much better that using a factory unit. I had expected noticeable improvement. It is better that the smashed over one we had that was caused by debris hitting the fins and does work well.

    As for the debris damage, I did see someone at the track with an interesting solution to that, they use a universal house A/C filter screen, just the bulk stuff and he cut to fit the grille and safety wired in place. I did not try yet but will let you know if works. Apparently not much restriction to air flow with that stuff.

    Regards, Jim
