So did the dyno runs take place last weekend in the Philippines? Any interesting results with different nozzle placement?

Yes we did 3 vehicles but 3 were automatics and with the extra power were up shifting so we could not get a read on the lower rpms.

The Toyota Fortuner which has the same D4D 3.0 Turbo diesel as the Hilux we did was the only one to use the dual nozzle set up but has full time 4 wheel drive so we could not dyno it, Plus he had extra mods like a front mount and Unichip, But lets just say he could burn the tires around the corner even in 4 wheel drive.

The Hilux picked up 25hp across the board using a 2gph nozzle and isoproply alcohol, Switch to a 4gph and 50/50 methanol and it shot up to 70hp and more than 100lbs of tq more if you look at the chart progression. We could not actually get a read on the lower rpms but at 3000rps it was making 56hp more hp and I believe 80+lbs of TQ more. The Kia Sorento had the triptronic tranny and it could not be dyno tested due to the vehicles self protection it would force a shift even in the manual selected mod. On the streets with 4 people in the vehicle myself included it was ripping the tires loose on the 2nd gear shift with the AC on full so I would say his increase was around 50hp or so, We ran that one on 90 proof Gin

We also did a Landcruiser, also full time 4 wheel drive, 3gph nozzle 50/50 mix, If you no what there intakes look like it sits right over the dang turbo and gets extreamly hot, It was a beast on the streets to drive. The owner said he thought we put nitrous on his rig.

I'll have alot more coming soon as more of the vehicles get the kits installed.

The Hilux dyno
Base, 2gph rubbing alcohol, vs 50/50 methanol, Like I said the power was to much for the tranny to hold in 2nd gear so it would up shift. The only problem with the Hilux it was overfueling in the top end and could really use the Progressive Controller. But the low end power was so strong the owner did not want to change down to a 3gph nozzle which would still have given a easy 60hp gain in the lower ranges as well. This thing could smoke the tires with ease after the install.

Thought i would post a little update on the toyota fortuner 3.0 d4d.

I had originally a dual nozzle setup, "1gph pre turbo and 3gph inlet" which was great, but decided to install another nozzle post turbo pre intercooler which for now has been doing a good job.

Now i changed the nozzle size on the inlet from a 3gph to 4gph and all i can say is wow, its really made the difference i was looking for, now finally seeing below 30c on my inlet temps.

So currently, this is my setup, 1gph pre turbo, 2gph post turbo and 4gph inlet.

I know the post turbo, pre intercooler is not recommended, however, with the length of my piping which is stainless and the heat in the engine compartment i thought it would be a worthwhile experiment.
The piping is still hot to touch, when it is switched on, even hotter when switched off, so i would say its safe to say it is evaporating and not pooling.
I would say that it is taking the edge of the turbo heat only.

Would it be worthwhile trying a 3gph on the post turbo or just stick to the 2gph?

Any thoughts / advice on this would be appreciated.

I will not be changing the pre turbo nozzle, as i feel the 1gph is more than enough on the vnt, it spools quick enough and builds boost quickly and easily, currently just below 1.7bar of boost.

With the climate there it's hard to say, a gallon per hour can make a big difference as you already know. But you don't want pooling in the intercooler either. Wish you could get that thing over to the 4 wheel dyno and see whats she's making over stock.

That is going to be happening very soon, just waiting to get a switch so that the unichip can run in multi map modes as i dont want it on full power all the time, plus a few other bits and pieces to be done, but hopefully wont be much longer.

Will post the results when it is finally done.

Might try the 3gph nozzle on the post turbo pre intercooler just to see what happens then, if the pipe gets too cold like the intake then i will know its too much i guess.

Thought i would post a little update here as it has been a while.

Been having a few probs over the last few months, one thing after another as always plus trying to get other things done as well.

First of had been having a few boost leaks, small, but still leaking, but they were finaly found and sorted. Then had some small adaptors welded onto my pipework for the nozzles to screw into to try and prevent the leaks there, which seems to have worked.

Now i actually read about the controller problem which is the same thing that i experiance, except it only happens when on the nlex, slex and running for prolonged periods of time, the controller does the blinky act to say there is a problem, but usually i have just been switching it off then back on again and it works fine for a good while again, before it does it again, however when running around in the city it never does it. I have not changed it as i dont like the big boxed new controller that it here, its not so easy to shift on the fly either, was kinda waiting for the new digital 52mm dia to come out so then i would just purchase that....hint hint...if this is not going to happen soon then i guess it will be the big black box.

The next thing is the pump is most definatly dying, several things tell me this, on lower boost the temps to drop a little, but when the boost really comes up, so do the temps, where as before they dropped, plus i am hardly using any go go juice, so will pop back to sids to see about changing the pump.

I have changed the nozzles again, currently 1gph pre turbo, 1gph post turbo pre ic, 3gph post ic and a 1gph at the throttle inlet.

I also dumped the sluggish viscous fan in favour of a dual spal fan setup with controller, which has helped nicely.

Once i get the pump sorted, will see about getting on the dyno finally and see what i am pulling.

On a final note, doing some calcs at the moment for possibly changing out the turbo, dumping the toyota vnt for something else that will get me over the 2 bar boost level with around 46lbs/min airflow and a lot more fun, if i have done the calcs correctly, damn constant 4 wheel drive is a power sucker, so is the auto box.

I still have not finished with the pics of the last 3.0 unit as i promised before, i will get around to it soon. Also trying to get one of the guys with the 2.5 to take the plunge soon.

Cheers
