I've been running the BB G3 with the latest comp profile for about 1000KMs so far and it appears to hold together well. I can swap this one with any G3 owner for free. PM me if interested.

Dyno results of standard and latest BB unit:

result only shown difference in 4th gear to floor. the transition and throttle response between the two is quite different.

looking at running water meth injection, whats a safe boost level for the tATR43?

You can run till it stops making power. Around 24psi

Hey Stao do you mean even my thrust bearing g3 can be updated to BB aswell as the updated comp housing?

Yes I can rebuild your bush bearing G3 into ball bearing and updated comp housing. in this case I will swap you with the one that is currently in my car free. I will need your turbocharger back for a day or two for a small modification on the turbine housing as well as the comp housing.

The ball bearing update can apply to all Gx, Gx based Rb highflows, SS2, and SS3 turbochargers.

Hi all,

Went out to WSID last night to run the car for first time since my PU highflow.

First run was a 13.2 @ 115mph with a rubbish 2.2 60ft

Second run does not bear a mention and then it PISSED DOWN RAIN

I was really hoping to bust into the 12's but im not sure it (or the useless driver!) will manage it.

Anyway, just thought id share that with the internets

It dyno'd at 280ish rwkw but it does feel a little down on hp. That being said i did have some problems with traction off the line.

What sort of trap speed should i be expecting assuming the 280kw?

Well to get fast time you will need small rims with fat simeslick tyres (hint from Trent), I used to skit all over 3rd gear with a G3 on my road tyres and that was a slow 330rwkws. Run RSRs or better will help heaps.

After doing abit of reading on the net, its not a bad time for a stock weighted R33 internally gated, stock manifold on pump 98 at that power level, there is a huge difference in mid to top end range torque with high mount and external gate after 120km/h. But I don't know how the car run slower and slower after each pull.

Also G3 is changing, I will post some photos of the latest G3 tomorrow, in hopping for the same power level with much better throttle response, it will also be equipped with the latest bearing and lubrication setup as well as optional ball bearing.

Nice, sounds on the money to me. I did 13.3 @ 112mph off a 2.2s 60ft with a bit less power on street tyres on an airstrip with my GT3076R. Put stickier tyres on it and ran 12.6 @ 112mph off a 1.9s 60ft (same strip, same driver... I was still learning how to make it work, not great traction) - it took me low 2.0s 60fts to get into the 12s from memory so not far away.

I reckon the delivery of the turbo plays a definite part in the ET, and the on-off responsiveness between gears in the trap speed and ET for sure. The G3 as Stao says has good 'rush' up top, but a little lazy in and out of gears (on stock manifold low mount I mean) and kind of like a light switch delivery in 1st and 2nd which makes juggling bog/wheelspin hard off the line.

And obviously driver experience at the strip :P

Yeh I think Luke's and my trap results are very effected by boost response between gears. Took the car for a drive the other night and tested that out, and I've got about half a second to a full second of lag between each gear change.

You will find the BB G3 with the latest comp profile changes that power delivery behavior by a lot. It smooths the power delivery pattern, which takes out that big launch behavior, sticks the car on the road better.

That lag you explained would absolutely kill mph, if its that bad...glad im auto..lol,

looking at the G3 drag vids, they do look lazy

cheers

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
