nelsonian101 Donating Members 961 Member For: 16y 6m 11d Gender: Male Location: Sydney Posted 12/12/13 11:52 PM Share Posted 12/12/13 11:52 PM Had a crap circuit session at Eastern Creek GP circuit last night.Car would not get 2 laps in before over heating.Usually only do winter track days, now remember why.(Vented bonnet going on for 2014.)As you may know, I have a lot of experience now with these cars at the circuit and attempting to reduce heat.Already have a transmission cooler, engine oil cooler.Coolant watchdog alarms, rubber strip removed from bonnet, big cooling fans in the pits with bonnet open, coolant additives etc, excellent car maintenance.Stock radiator has also been replaced with a Fenix.Problem is the cooler set up in these Turbo Falcons.Air has to pass through the intercooler, Power Steering Cooler and AC Condensor before even reaching the radiator.This is a unique problem for circuit cars and not experienced so much on the 10-12 second drag strip.Heat soak (and air intake temp) is less critical for me now compared to radiator flow.The stepped PWR intercooler I currently have is partially blocking any flow to the radiator on the top section.2 questions:1. What intercooler do you recommend that is very thick at the bottom and light (don't mind front bar cut now) but still allows flow at the top grill intake?2. What are your thoughts on cutting/ re welding the current Stepped PWR design, allowing more flow to the radiator?(I am also considering option to relocate the Power Steering cooler and condenser or even cut/fit a smaller condenser)Front ducting space is minimal now as both fog lights are already removed for brake ducting/oil cooler.Any ideas?

dustyae86 Member 46 Member For: 13y 2m 30d Posted 13/12/13 08:31 AM Share Posted 13/12/13 08:31 AM have you tried ducting better, like so the air that has the opportunity to go in that area is forced through rather than blowing out the sides? you would be surprised the difference this can make 2 Link to comment Share on other sites More sharing options...

I run the 800hp Rapidsystems cooler and this year I've done 16 track days without ever getting over 2/3 on the gauge. Do you still run the stone tray on the bumper?

I removed part of it when the brake ducting was fitted (from a V8 brute direct to inner front hub) but thought full removal would create a high pressure zone under the car not allowing the air to escape after passing through the radiator. This may be ok for non vented bonnets though, but the opposite appears true for cars with vented bonnets which I will be fitting soon. Link to comment Share on other sites More sharing options...
BRK Member 361 Member For: 13y 23d Gender: Male Location: Perth Posted 15/12/13 03:31 AM Share Posted 15/12/13 03:31 AM Good luck with this. Not much space to increase radiator capacity and the more core thickness the harder it is to get the air thru. There are very few fans on the market that could be fitted in the space that are better than the factory units. However, maybe some electrical changes might help. The fans use DC motors and so perhaps you could up the voltage to 15 ( or so) and increase their rotational speed. There might be a bit of "design space" in the blades to allow for better airflow at higher speed without producing stall.Mods to the A/C condensor is something else to consider but not sure how that would affect its performance.
