I have the same cooling setup as you have, make sure that the air cannot pass the radiator in any way, tighten it up with a rubber seal the whole way around and it will work.
I haven't done it yet, but I'm going to have a small scoop behind the wheel. Together with the window scoop and maybe with an optional air intake underneath there will be a lot of air pressed through radiator. If you go the same route also make sure that the air will be forced through the rad and not out via one of the other intakes!
Looks like a great project! |

thanx sven,
we've got a pair of strong cooling fans to pull air through the radiator, and the plan was to test airflow once she's running and if neccessary add more vents, vent scoops etc. |

Looks good but add a rubber sealing.
Air uses the least resistant route, and pressing air through a rad is resulting in a lot more resistance than flow on the sides.
People (not only here) tend to put bigger and bigger rads and intercoolers on their cars for better effect, but usually it's just waste of money. Force the air through the rad!
I've been part of a couple of airplane conversions, and if you did see the size of the rads used on them you would be surprised. It works, because the air is forced to go where it should be.

svens right, SEAL it SEAL it SEAL it!
I've run my rad there when I first did the conversion on my diesel van it didn't work for me btw. Though I shouldn't think it will be such a problem with a petrol engine. Diesels tend not to produce much heat whilst ticking over but under load they produce far more than petrol I reckon. All the petrol vehicles in a range always have smaller radiators than the diesel engines do.
I hope it works but did I mention that you need to seal it? |

Yeahbut, the fan's running all the time though..... _________________ The advice you receive on here is worth the paper it's written on.

Oh and I haven't seen many aeroplanes sitting in traffic jams lately. |

Well you know the fan's only there to cool the pilot. Turn it off and watch him sweat.

"The fan" doesn't do much of the cooling when marching around 100 knots. We used a rad smaller than a Subaru intercooler for a 6-cyl 3 litres engine, and still it was cooling too much on altitude.
All I have to say is; add some rubber.
Oh, and by the way, I think we all can agree that the location of the rad and traffic jam is not the issue, even if it's an aeroplane... |

Hey dont worry Sven we are going to seal the rad before its bolted in for good. I just posted that pic to show the fan setup. I'll post another pic once its done, almost finished the wiring and should have the new gbox in this weekend, so it wont be much longer. |
