hi has anyone fitted a sr5 bonnet scoop to a 150 .
if so do they have any pics
also is there any advantage to doing it
or is it purely for show

Purely for show on a 150... Would look silly I think.

On a 120 the bonnet scoop directs air through the intercooler which is on top of the engine. On a 150 the intercooler is in front of the engine/radiator so fitting a scoop will only be for aesthetic reasons.

When stationary for a period of time or travelling at very low speed it would assist in removing heat a lot quicker reducing the effects of heat soak, one would think. It would look good if you had all the other gear on as well like bull bar etc.

Go for a big scoop like on the 70 series. I reckon that would look better on a 150.. Just be a lot of extra fabrication.

It can be very dicey fitting scoops to things that dont have scoops. Reason is to do with high and low pressure systems infront and behind the radiator. Most vehicles operate with a low pressure system behind the radiator to help draw air through and down out the tunnel.

Sometimes if you fit a scoop it can create a high pressure behind the radiator which can increase engine temps as the air movement through the radiator can be reduced.

Over on the LCOOL forum a similar topic has come up.

Fascinating :-)

The 150 must have one of the worst intercoolers ever for a factory car. I wonder how it could possibly work. The airflow would be terrible with the ridiculous 90 degree bends in and out. It would be lucky if even half of the intercooler core actually does anything. With the A/C condensor sitting in front it is more like an interwarmer than cooler. I am waiting for someone to bring out a water to air intercooler kit, there must be some serious airflow restriction and HP losses with the existing 'cooler.

That's how most factory intercoolers are..
