Going back on the dyno

[AldoR]

Car going back on the dyno, Now with the cold air feed sorted I would like to see if there is an improvement even if just a little will keep use up to date when it's going back in.

I'd be concerned where your new air feed takes in air, it's right I line of any water and road debris. Just a real concern I'd have Aldo. I never realised until I stripped off the bumper but the standard intake for the air cleaner is tucked up inside the offside wing so it's not drawing hot air

This is a good point to raise I understand some 260 owners use there v8 as a daily drive all year round. I only use mine at the weekend during the hight season and it still has its risks ie heavy rain flash flood. Was driving through a flash flood on my way home from Grantown on Spey car drove great so am going to continue were the air intake is positioned as I have a few air filters I want to experament with the one on the car know is the pipercross venom am not sure about this one I think it's not big enough. Will get it on the dyno and compare readings from previous run mate.

For what it's worth my last company made automotive air intake ducting, the car manufacturers try to draw intake air from an area of steady pressure, such as under a wing, or behind a headlamp, as that gave the best results overall, these positions also tended not to hydrolock the engines......

The standard air intake has a 'snorkel' that draws air from just under the bonnet on the O/S. I've modified mine and removed that part.
The picture is old, later I removed all the plastic above the clamp to have just the filter exposed.
Not had a problem with water or other

I am convinced that the current air intake box is not supplying suffisant air due to its size whats your thoughts.

There are a fair few S/C cars out there with a standard intake.
The whole filter assembly is certainly capable of supplying enough air.

Only reason I modified mine was to get rid of sucking hot air from under the bonnet.

Hermen am referring to the new pipercross filter as it's smaller think I need to get a larger intake box your though and anyone else on this would help thanks

It does look a bit on the tiny side

I measured underbonnet temperatures in different places and various speeds and found that at round town speeds (sub 30 ish) the temp at the air inlet was similar to temp near the inlet manifold area, but if you are travelling at say 60 plus the temp at the air inlet was only a few degrees above the outside temp ,so I left the inlet as it was.
