Unsure how true, but have read people say when it's high revving all the time you need to slow the water down through the rad (rather than speed up - drilling thermostat). Obviously you had an issue prior to drilling though so not actually any help.

 

Fenix rad, 1 factory fan, water cooled turbo & fmic with no issues, although very minor track work compared.

Depends what you read... the cavitation problem is not supposed to be bad with the JDM water pumps... the USDM pumps which are fitted to lower revving

2.5 litre motors are worse. 

 

If fixing the air flow through the radiator and adding a separate radiator for the turbo doesn't work, replacing the main radiator will be next.

If there are still problems, maybe an electric pump and/or get the tune checked... maybe taking some timing out will help, but I'm not

keen on losing power :0

Might have been something very simple it turns out... the radiator cap not holding bugger all pressure :$

I've had the turbo water system separated out anyway and I think some radiator shrouds have been added. 

There is a short hillclimb on Sunday so it should be obvious if an improvement has been made.

What do you mean 'you think shrouds have been added'. Did you drop it off at Al's and say 'fix it'?

 

Yes, doing too much of that recently, but I have no time and no decent workspace and am sick of missing out on racing.

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
