 1JZGTE - Maxed out my injectors

Just got my stock turbo 1JZGTE powered Landy dyno tuned for the second time. Mods are Large FMIC, 3.5" exhaust with dual dumps, Haltech E6X, Bosch 044 and pod filter. Anyways recorded a best of 260 hp at the wheels, boost was restricted to 14psi cause of this, probably dont want to go higher anyway.
Compared to other similar modded 1J's with stock injectors my hp is very low, man my transfer case and tyres must have a huge influence on the dyno reading and power being transmitted to the rear wheels!!!!!! Id hate to see what the hp level would decrease to if i put it on a 4wd dyno with the 4wd engaged. Swinging an extra 8" diff wouldnt help either.
AFAIK it was done in shootout mode, ill post up my graph when i get the car back from the tuner tomorrow.
Will it be worth upgrading to 440's and run 16psi, much more power to be had there???

based on how much 440cc injectors are, I would get some and sell the 390cc ones. Supposeably in a perfect world every extra pound of boost should net you 10kw. Of course there are many variables especially efficiency range of the little ct12a's but it gives you a general idea.

hi mate,
yeah your 4wd tyres will make a big difference....
i know a stroked 5l (out to 5.7) with a blower that "only" made 130kw at the wheels, but ran a flat 13sec 1/4... go figure....in a hilux
the bigger the rolling diameter the lower the figure... put a set of 10in rims with low profile rubber on it and that will give a figure that all the dyno warriors will blow over....

Skip, which dyno (shop) did youdo the power run at?
And did you specificaly ask for a power run? Mine was dyno tuned last week. Tuner gave me a graph with a max of 234rwhp at 12psi (similar mods to you but without twin dumps), but then added that it's probably making around 210rwkw  .
I'm going to work on improving the cold air feed,then take it back and specify that I want a (gloating) power run.

Skip is there a URL where pics of your car are, I want to show my dad that someone actually has the balls to put a 1JZ into a bunderra...
He doesnt belive me...what a fool...

Justin: It was done at SST, not just a power run but had it retuned. Your power output just goes to show how much power my transfer case, R151f gearbox and hilux diff robs. Also that my massive diameter tyres effect the reading. Knowing my injetors are maxing out shows just how much power im making at the flywheel.
MR 1GGTE: Cruzida hosts some pics here http://oz-enet.com.au/~peewee/Skip/
If you think it takes balls to insert one in a Bundera you should try taking the thing to 180km/h. I swear all it would take is some small wings to lift off, i dont feel particularly connected to the road surface at speeds above 110km/h

i got a 1jz in a lux.. single turbo conv.. factory ecu, auto box
dynoed at 197hp at wheels at 8 psi..ya tyres would play a big part in hp loss...definetly get bigger injectors better to be safe than sorry, and if your turbos r standard 1jz ceramic becarefull of to much boost they dont like it...

its 2wd...but i know people with 4wd having probs with drivetrain due to abuse,, which is nearly unheard of with 2wds.. tyres play a big role in that..seeing as u are running haltech why not get us spec 550 injectors. then you will not max them out until u upgrade turbos,,

Latest dyno graph, props to CrUZida for hosting it.
Graphs are before and after, fueling wasnt to crash hot before!
onemxracer: To use the extra fuel provided by the 550's id have to bring boost up past 14psi on the stock ceramics which probably isnt the best idea.
