Has anybody heard of doing such a thing? I know the 99-2005 Jetta has the intercooler in that location, albeit with poor ventilation and ducting, which is what I think of when I see that large, unused opening in my potential bumper swap. With such a substantial opening in the 99 spec bumper for the passenger-side (US) oil cooler, would it be a worthwhile move to place a Greddy SMIC into that location for more, fresh air flow and also allow for the radiator to flow more freely, with less resistance and turbulence on both sides?

Is the Greddy SMIC designed for a particular flow direction, or can it be mounted backward to accommodate any piping clearance issues? Is there a better intercooler option for that location?

Is this whole idea horrible for any reason, other than over-engineering cooling functionality?


My second question is regarding radiator air dumping. Is there room/clearance with the 99spec bumper to mount my Fluidyne vertically while retaining enough front coverage, and build a duct to dump the backside air beneath the engine? My thoughts are that with low air pressure beneath the car, it will pull air more quickly through the radiator and keep the engine bay much cooler (even at low speed) by physically moving the used cooling air out and away. With the fins providing resistance, is it appropriate to assume that not enough air will be added beneath the car to induce lifting at high speed because of physical limitations on air flow through the radiator?

 

While you have an original idea, I believe charge piping for fitting an intercooler in the passenger side oil cooler location would be a nightmare (or at least more difficult than it should be). This would also increase your turbo lag (boost threshold) and the net benefit wouldn't be that much lower IAT's than with an equally efficient IC core in the stock location.

Not to mention, you really should do dual oil coolers. Rotaries rely on oil cooling more than traditional piston engines, so proper management of your oil temps can help keep coolant temps under control, as well.

You also have your pressure vanes mixed up- under the car is high pressure zone. This is due to the car being shaped like an air foil. Air traveling over the top of the car must move quicker to meet up with air traveling underneath the car, due to the rise of the cabin area. So air is trying to rise up against the bottom of the car. Venting to the underside of the car would be futile.

 

for all that fab and cost - I would go V-mount. Its proven and there are kits if you don't want to fab your own.

 

Gotcha, thanks for the info and corrections. I certainly don't want to create turbo lag. I'll take a look at V-mounting kits.

 

User "driftxsequence" made mention of having one in this thread. Send him a private message about it. I have two so... I will make one of them work for now. I have been using rust reformer on many things that can't get the electrolysis. Thanks for the suggestion.
