Bushskinz Intercooler Issue?

[NTBenny]

Getting the correct airflow is not just a matter of more holes in your bash plate!

You want smooth airflow with little turbulence going to the face of the heat exchangers, shrouds and air deflectors may be required. Air will take the less path of resistance and an open sided bash plate whilst offering protection and cheaper manufacturing costs, does not promote good clean airflow.

Most designers and manufacturers of bash plates do not have an engineering degree or even an advanced understand of aerodynamic principles. Start talking about positive and negative pressure, static and dynamic pressures, boundary layers, laminar flow, induced turbulence, aerodynamic drag, convergent and divergent ducts, venturi effect or standard wave ratios, and they glazed over, like you are from another planet.

As usual it sounds like you might be able to add some valuable input on this subject OJ. Have you considered any other options?

What about a simple water sprayer setup to mist water over the intercooler core. Could be as simple as a windscreen washer pump and reservoir (or complete washer bottle + pump assembly) activated by a toggle switch in the dash misting water through garden misting nozzles, to a full blown automatic setup that triggers when a pre set intake air temp is reached with quality pump and misting nozzles. I had a water misting setup on the intercooler of my VL Turbo Commodore in my younger days that was triggered to fire at a preset boost level. I found it very effective at lowering intake temps and thus reducing detonation.

Yes this is an option for a road car which is very effective as long as your water supply lasts, but what happens off the bitumen when on a dusty road. You can see the amount of fine dust that gets in the engine bay so would the dust combined with the water mist for mud and block the air channels of the intercooler.

Mods I am thinking of are easy, simple and cheap. If I can improve ram airflow, keep the intercooler clean and force more air through the intercooler then temperatures will come down. When travelling with Pajero's fitted with Bushskinz intercooler plates and traversing deep soft sand, there is a buildup of sand in front of the intercooler which results in inlet temps rising quickly. My plan is similar to the mods I did on my Challenger, cover all the air vents up on the intercooler plate and fit side gussets but also looking at putting 10mm to 15mm spacers under the front attachments to create a ram air slot.

Will test and report back.

You are right there Old Jack. I did not think about that I must admit. I am thinking about my driving which is mostly on the blacktop, which I suggest the majority of Pajero owners spend most of their time. If this was the case, water sprayers would still represent a viable and cheap option.

OJ,

I've added gussets/flaps to seal the sides of the Bushskinz on my Challenger.

Easy to fix a flap of rubber to the chassis rail with a few spots of silicon.

Added benefit of the flaps is that they keep splashes of mud and crud out of the intercooler & radiator.
