5 GT Turbo Pace charge cooler

[vassilisa]

Hi all,
Has anybody any experience using the charge coolers produced in the old days by Pace?
My concern is whether it can cause an air flow restriction, in other words, for what kind of horsepower they are rated.

Many thanks!

They used to be fitted to all the top cars back in the day with measured improvements.

That said - big I/C any day!

I had the very first version that fitted in place of the std IC, is was great for upto 1 bar of boost, but the pumps then were shit.

The later version pictured above came in low and high boost versions. The low was good for 20 psi(?), but the high was good for 70 psi. They also used the super reliable Bosch water pump.

Bottom line. I like them, but there are other solutions (cheaper and more expensive), but it depends what you are doing with the car? Drag, Race, Fast Road, etc.

As covered early pumps were not very reliable but a fan of cc setups which can work really well

I reworked my old pace unit in the end on the vag converted 5 with bigger pre rad, bigger header tank, larger pipework and larger pump......in the end replaced the core with a wrc core to the same dimensions and never let me down

At your stage would consider larger header tank / pre rad is temps are an issue along with check the pump

Thanks for the replies guys!

I already run a large prerad (almost 3 times bigger than the one supplied) and a quite big water pump; I definitely agree, the supplied ones were crap. The header tank is from another Renault model. Estimated total water capacity around 4 liters, should be ok I guess
The pump is controlled by the ECU; when intake air temp passes 30°C (configurable) it is activated and circulates the water.
The car is used as fast road (no track - race etc) and the aim is 20-25psi.

Thats a very sensible setup, I like it

I use the Pace High Boost Chargecooler on my car and run up 25psi with about 200 brake being made (need a bigger cam) & to be honest over the last 4 years, never had a issue. A bigger pre-rad is a great idea and that's I will do when I get round to changing the Carb Setup to EFI.

That's very reassuring, the only question is now how can one distinguish a high from a low boost unit?

I don't know the answer to this, must be a difference in thickness of materials / core used.

I can't see a stamping on mine other than paces logo, will look again.
