Outer Limits 4x4 Board

Well, it's taken a while, but we finally have my top mount intercooler I built up and running on a mate of mines GU 4.2 turbo ute.
He is running standard boost of 7 psi and it's interesting to note that on a test hill near his home in comparison to 2 basically identical GU utes in terms of tyre sizing and gearing but differing boost levels. One has 11 psi and one is running 20 psi both non intercooled.
In speed tests up the hill, at the top of the hill my mates truck is 5 kmh faster than the 11 psi one (which has had the MTQ turbo treatment on both exhaust and compressor side). The other ute is basically a competition one but with just the boost and fuel timing changed (not a modded turbo as far as I know) is level pegging as far as speed but his exhaust temps are off the map
My mates exhaust temps are lower, the mid range power is markedly better and he just recently told me he is getting better fuel economy than he has ever had before. (12.3litres/100kms) (22.9 mpg)
The next step will be some turbo mods to see if we can get it sing even better
I don't have any pics on the scoop assembly but it is placed nearly central in the bonnet rather than off to one side like the factory one.
It has a rubber seal which seals on top of the stainless steel shroud so that all the air entering the scoop has to go through the I/cooler, it is then directed backwards and downwards to the transmission tunnel by another stainless shroud underneath the I/cooler core.
The I/cooler core I had custom made to my specs and is an extremely strong tube & fin core from Adrad industries. (they make the finest I/cooler cores I've seen)
Regards Andrew.

Nice looking setup.

congratulations!
that looks like a very neat job and good to hear it performs the way you wanted. if it's ok to ask, what sort of moolah did that set you back and is it a one off? very cool

No idea on total price but just the bonnet scoop and rubber seal cost about $300 (the seal cost far more than the bonnet scoop ) I think from memory the core cost around the $400 mark (custom core made to my specs) and LOTS of hours working it all out.
I wouldn't mind building a water to air intercooler for a project, it's a pity that HeathGU is so far away, I'd love to have look at his ARE water to air setup.
Regards Andrew.

Did you get the diesel pump changed at all? Recaibrated for extra fuel or anything?

Cheers

Do you have plans to produce this on a regular basis or was it a one off project only?

I've been tentatively looking into this but haven't found much around Melb that's worth investigating further. Most just say, "yeah, we can prob chuck something together for you" which doesn't really inspire much confidence!!

Looks like a great job and would be interested in having a look if you decide to start building these.

Cheers.

Give andrew a call D&F Racing Carrum Downs.
his welding is a work of art. This IC originally was going on my car, but with the denco system it wouldnt fit... If you look closely theres a white stripe on the IC... thats when I first saw it.
