Hello,
water cooled 914 here. I have an LS6 motor I'm dropping in. Has anyone ducted a radiator successfully without cutting the front bumper? I'd like to keep the bumper intact and use a front lower valance for an intake. Was going to lay the radiator in the front trunk at an angle. Thanks! Bill |

The guiding principle for adequate air flow through the radiator, is pressure differential. If there is no pressure differential between the intake and exhaust air, you'll never attain success. As such, there are probably a few different ways to get it in a 914, and would take some experimentation.
You'll hear talk of "ram air", but that in itself will not work without sufficient management of the exhaust air. If you find a good area of low pressure, then the intake side almost takes care of itself. I chose to exit the air through the hood with a diffuser that has a raised leading edge. The intake is through the front bumper, which is probably larger than needed. I may wait until summer to tape-off the intake to see how small I can go before it affects cooling performance. Andys |
