Fitted the plenum and connected to the throttle bodies with 50mm long silicone joining sections. Had connections fitted to the ends of the plenum to allow straps to be fitted to hold down the plenum under boost.
I fitted the boost Pipework and used 3 inch aluminium tubing between the elbows. The charge cooler is 3 inch in and out and then the plenum is also 3 inch. Covered the charge cooler in reflective heat shield to try to keep the coil cool and to reduce heat soak from the engine bay.
Fitted a second water pump and radiator for the cooling water system on the charge cooler. The pump runs when the engine is running and circulates water between the rad and the charge cooler core.
The car is now off to RLM for mapping, so fingers crossed for a good result.

ReplyDeleteI cannot see the radiator for the charge cooler ? Is it a dedicated one ? What is its size and what are the intake temps you get with it ? Turbo pressure, ambient and intake temperatures ?
With this setup, do you manage to keep intake temps constant during track days ?
Cheers,

Hi Jeremy
ReplyDeleteThanks for the question. The radiator for the charge cooler is fitted below the main radiator and it is a dedicated one for the separate cooling system.
I ran it a couple of times on track at the back end of last year and worked fine, with no drop in performance. I had been running between 0.6 and 1.3 Bar and was fine. Even during mapping it held the inlet temps down.
I plan to do some logging soon and to see if it degrades in performance in the warmer weather. Still in two minds whether or not to swap it out for a front mounted intercooler.

Hi Eddie,
ReplyDeleteThanks for the reply. This is a nice setup you have here. Logging inlet temp is interesting as the most important is to get them as constant as possible. This helps a lot to get reliable.
