Du kan jo da kombinere litt:
- ekstra oljekapasitet - skal du bygge denne bilen for banebruk bør du kanskje uansett vurdere tørrsump så du ikke mister oljetrykk i svingene
- bruke kjøleblekkene over sylindrene/toppene med to separate vifter, da er det bare å sveise igjen toppen (der viftehuset sklir nedi) og sette to rørstusser på for tilkobling av luftslangene.
Easy peasy og velprøvd innen dragracing - med to böse vifter blir det sikkert nok!
Her er enda en variant - men KUN til å kjøle ned toppene etter en kvartmil, siden disse ikke leverer på langt nær nok luft:

"They pretty much suck. When I switched to those, I watched my head temps SOAR. I knew it would run hotter compared to the fanshroud but being a drag car I figured the added cooling while the engine was turned off would offset them.
Boy was I wrong. They don't blow air for squat. Going through the traps my head temp (under #3 spark plug) was 425-450. That's just starting the engine up, doing a burnout, staging, and taking off. Never mind after that I still had to drive the car back to the pit space. Honestly, the engine ran cooler with no cooling system on it at all. My heads were cooler going through the traps with a bare motor by about 50 degrees. Still much hotter than with the stock shroud of course.
I have since switched over to E85 to run cool enough with those fans to make them work. No doubt I would still run cooler without them, but I spent $100 on them so by god, i'm going to use them.
I was talking to a friend of mine that also runs those fans and told him how hot the engine ran with them on and he told me "I've never had a problem with mine", to which I reminded him "You don't run a head temp gauge either". He laughed to me "I don't want to, do I". LOL. I guess they work fine if you aren't looking at what they're actually doing I guess.
