Random indeed :-(
Anyway, I have no explanation for that except perhaps the clip wasn't in deep enough.... Of course, the cover coming off hit the comp wheel and its probably spinning a good 100krpm.........
Don't expect to ever see another one like that. Strangely it has been on for over a year!
Its not the kind of experience I want for my customers, but the upshot is that Cranky now has an upgraded Gturbo Bad Boy

Well, this week Im tuning a 2008 Auto Hilux D4D (1KD-FTV) with my Grunter spec VNT
Im hoping that with only a 3" exhaust and poor factory intercooler I can get a reliable 150kW @ wheels (std ~90).
We'll see........
After that comes a cooler upgrade......

Factory intercooler starts deforming at 20 psi then pops of the end tanks at 30 plus psi

That's a bit s***!
One of my mates is planning on Graemes turbos on his lux, doesn't really want to upgrade cooler tho.!
At 20 psi started to see deformation between the core and the end tanks of the intercooler. Any thing over 21psi you get horrible pressure drop.
Which vehicle is this?
Hilux D4D 1KD-FTV
Thanks. That's a seriously weak intercooler for a modern vehicle.

Post up a nice, in focus, steady movie of all the gauge readings at the same time on the same screen....... or graph it all up on a single readable spreadsheet.
New turbro has been on a few days now, went for a decent drive today, still need to get rid of a bit of fuel down low but very happy with mid and top.
This new turbo is definitely better, it seems a lot smoother as it boosts, doesn't ever seem over stressed at all...
Spent a short time on a very soft beach with the tyres up and it did awesome, had to drive a bit sensibly unfortunately due to the company I had in the car, but at one stage I saw 28psi @ 1800rpm! (i have my boost set at 28)
On the flat gravel with tyres at 20psi doing 100kph, it sits nicely on 12psi and 260-270deg post turbo.
So all in all its tip top!

that's an impressive number .. ! ( I mean that amount of boost at that low rpm range )
Thats great. Well, you do have the "all new" version 2, so I hope its better than version 1 lol. Quite a lot of changes actually.
Torque at 1800 and 28psi would be......alot

OK, well I'll do that on a manual. This is auto and the computer doesn't let boost rise up in 1st few gears. In 4th at 26psi, its going pretty hard just on rail pressure increase. Wait time some inj duration and timing is wound in
Next week I have a manual and it has a FMIC, so that will be interesting since they badly need a FMIC and the std turbo is not good at high boost with a good cooler and exhaust (the comp wheel becomes divorced from the turbine....). Ill be data logging the std turbo then changing to mine. I am very certain we can do in excess of 150kW at wheels and be safe on turbo and engine.
*EDIT* Today I received the manual Hilux in exchange for the auto (its ~ 110-120kW at wheels right now - very lean. Ill get it back soon for the big tune but want to do manual first as much easier to tune low rpms in manual). On the manual, the FMIC is fitted but not plumbed. Still has std turbo. So, Im data logging tomorrow. Then it gets intercooler, exhaust and Gturbo and a retune next week
Having done a lot of Landcruisers and know what they do power wise, its fun to play with something that has a whole new set of issues......
By the way Ozwallaby, when I get cars, they have whatever gauges are in the car at the time - usually pillar or centre console (both away from tacho). If your happy with a manually entered plot then I can probably help with that. The problem is that some ask for details because they are cynical. This is fine, but makes the time I would be spending putting together a excel graph wasted time.

I (and I would imagine many others) am certainly interested in as much data as possible, especially comparative stuff that shows how one turbo reacts/performs compared to another, with as much info across all datasets as is available.... as far as I'm concerned, in the world of testing/comparisons, the more data the better...
As we know, in ANY field, there will always be detractors and supporters.... I just want raw info so hopefully I can come to my own conclusion, flawed tho it may be..
Hope it all goes well G ....

Here is 1HDFT with Gturbo Bad Boy STage 2, very bad water to air intercooler (post intercooler temps 130C). Will be dynode again when intercooler is fixed.
this is real power at the wheels - ramp rate = 100, so nice and slow, power is at the wheels (no correction for flywheel)
Yes that is 35psi boost.....
Low end boost will improve when intercooler is working. You can see that at ~1700rpm its making 24psi on one run, then falters a little before it rises - thats compressor surge. Once the intercooler is fixed and temps post intercooler are dropped to 50 degree C or below, the surge line will move to the left and should move far enough to not be a bother

Another good result Graeme. Are those figures ground or flywheel?
Just put a decent size water tank on that intercooler and plumb it to a hot-wter tap in the back. Perfect for a hot drink before the first ski run of the day.

Hi Dougal, thanks mate. Power is at the wheels - the Dyno Dynamics always show at the wheels. People can tickle the corrections to give higher results but this is setup with a ramp rate of 100, so nice and slow, real power at wheels. The local Bosch dyno does back correction to flywheel (surprisingly accurately) but doesn't show low rpm correctly
Gday G, what exhaust, snorkel and injector pump mods if any were installed, and will this vehicle end up with a large front mount intercooler or stick with the pie warmer
