After a bit of info / dimensions on this intercooler if anyone can help.

1. what is the core size?
2. what is the dimension from pipe to pipe ends
3. what sort of power can they cope with.

Give Gary a ring mate am sure he will answer this question in 2 mins.

ill have to measure one,
power around 400 bhp on a evo and 1.8 bar boost.

ive got a std one here i can sell you

Good call i'll ring him in the morning:thumbs:

We need one that will cope with 500+ at about 2 bar.

we do a great upgrade one for

If you've got a 500+ cossie just go the proven methods and spend the money on the correct ic. A 5k ish engines not worth taking short cuts is it?

Our current intercooler is/was coping with 450bhp but the last time the car was on the dyno we had intake temps of 50 deg. Gordon did say that his air blower only produced airflow of about 30mph or so if memory serves me right.
It was for this reason that we wanted to fit an intake temp gauge to roughly see what was happening when out on track fro 20mins.

The other and main reason that we are looking to change it is down to air flow, restrictions and turbo spool. The design of the RS500 style intercooler we have has the inlet and outlet pipes at 90 degs to the cooler. This has the effect of slowing the turbo spool up.

The only intecooler that I know of for the cossie engine that gets around this is the new Airtec one which has the pipes coming out the top and are curved. In order to fit that one we would have to modify the slam panel or change the rad. (Can't remember for sure).

Either way it's a lot of work just to run a test that may prove not worth the hassle.

I've not been able to find any test results for turbo spool up with differing intercooloers on a cosworth, only on evo's and scoobys.

Cosworth yb's make good power by ringing the shit out of them.

Evo's make good power by being more efficent in how they work/designed.

There are some cossies running 500+ on less than 2 bar boost but as far I know these are all running stroker kits and you try finding any info on stroker kits for a cossie or try getting a price for one.

We plan to run the car at 500+ and for the turbo to work more efiicently than it is which is why I am looking at what the evo's are doing and trying to understand some of the diffences as we will not run more the 2bar of boost for the simple reason it's a 20+ year old block.

I hope this explains my wayward thinking and answers any questions:)

Development on the cossie lump basically stopped 10yrs ago......in the UK but the scandanavians are still at it.
Found this pic last night, so Alan's thinking must be on the right lines;)
