May I be permitted just a little bit of self-promotion, please?

I've just completed a fairly extensive update of my
website:
. Added a new page, "Operation", on using an EGT gauge.
. Updated the FAQ and Product Brochure downloads.
. Added Tech Talk 3 (on intercoolers) to the "Tech Info" page. (Yes, I know it's been on ExplorOz for months already. I've been 'gunna' add it for a while now...)
. Added Travel Updates for 2005 & 2006 to the "About Us" page, including lots of pics.

So, if you're bored on the holidays, please feel free to drop in for a look. If you like what you see, tell everyone! If not, please tell me.
Ian

Hi Ian,
Interesting reading the article on Inter coolers. I have had a 4.2 TDI Patrol for 4 years and have often thought about fitting a fan under the Cooler that could be turned on & off manually from inside to give extra airflow when it was needed. eg. in slow traffic or on a hard pull up hill with the van in tow.I believe the inter coolers fitted to the 4.2 are the same as was on the 2.8 Patrols and that they were fitted with a fan.
Your thoughts on the pros. and cons. would be appreciated.
Duke

Hi Duke,

My info on the Nissan TD42Ti says:
"Intercooler: Although similar in design and fitment as the intercooler fitted to the RD28 and ZD30 Y61 variants, there are some significant differences.
1. Deletion of the charge pressure sensor from the front of the intercooler.
2. Shape and diameter of the inlet tubing.
3. Deletion of the cooling fan from the underside of the intercooler."

So, it would seem a fair bet the fan from the smaller cpacity models would fit OK. (And by the way, point 1 above suggests a ready-made port for connecting a boost gauge, if you wanted to.)

I'd think the fan would definitely help in low speed, high load situations. As it is, at low speeds I imagine most top-mount intercoolers having a net UPWARD flow of hot engine bay air through the IC and out of the scoop. That's because the main cooling fan(s) are running at high rpm, slightly pressurising the engine bay with hot air.

If you do fit a fan and want to loan me your vehicle for a few weeks, I'll fully instrument it and tell you how well it works,OK??

Hi Ian,
Thanks for the info, agree with all you said. I will see if i can track down a fan at Autobarn or Supercheap to do the job.If you are still in Tassie and are heading up to the NW Coast (Smithton) give me a call on Member Message and we could catch up.
If you like Oysters i can get all you want fresh out of the water, still in there shell for $5-00 a dozen.

We might take you up on that offer, Duke. We're in Tas for another couple of months and my good lady just loves oysters! And I want to try a few of the west and NW area tracks on the "4WD Tracks in Tasmania" booklet... We'll be in touch.
