Corvette Z06 / ZR1 Prospeed C6 DUAL SPAL Fan Shroud Kit | INSTALL & Review

[@badzr1649]

Hey, hey John! Good choice there. That fan unit seems to be what the cognoscenti go with. You've been so helpful during my slow build... I trust you'll provide an update if there are any issues with reliability. Because... always with my own twist (or Im always broke and trying to save a couple nickels --hahaha!); I recently finished my own shroud for my ZR1, with two of the curved blade Spal 11" HO fans. I always deburr edges, so no (elevated) chance of getting cut. I also ran power and ground by 8 ga, fine stranded OFC cables added big metal-case flyback diodes to each fan and I use the OEM PWM control signal (intoCRYDOM 100A SSRs) until the Coolant hits 200 degF, then switch it all over to full 12V power using industrial 100A DPDT Relays triggered by a Setrab 200 degF thermal switch. I don't know how much money I saved (or spent), but I do like a few features in my Prospeed copy... Everything but the time to do it all myself!! Anyhow John, a very nice score and as always your implementation is superlative. Well done, sir!

Did you need to adjust the tune for the fans? I installed the DeWitts rad and fan and in hp tuners there is an option for duel fans

[@JohnFrancoNH]

No i did not need to but i am aware of the setting that you are speaking of. Its for setups that have dual stage fans. The prospeed still acts logic wise as a big single stage variable fan like the stock one.

@@JohnFrancoNH makes sense, thanks 🙏🏻

Hey Sir, how are the upgraded fans doing in the summer heat?

[@JohnFrancoNH]

Works great, out driving today 86F outside with A/C on. ECT didnt get over 200F. While driving it was 176-190F

[@True_Knight]

Awesome! I'm putting this fan setup on my list of upgrades. Thanks for the response, and the video itself!

[@JB-ej8zy]

What would you say the coolant temps difference was between this fan setup ?

[@JohnFrancoNH]

This fan kit does a great job in summer heat so far. Car stays below 200F even with A/C on thru out the whole time.
