Bah!

Yep at the end of the day, responsive turbo, heap of torque and power.

I'm asking the PSI question purely for speed in a straight line. I know the turbo has great response and torque, but does it keep pulling. This is where I get eaten alive and I'm not whiling to sacrifice response to gain a little in the straight line. As I know from comparison on the track there is little difference between what I have and a GT-RS.

Is that what you guys get up to over tuggers way!

Anyone know of I'm slipping in 4th and 5th

Will a new clutch put down more power in the other gears

Only if it's slipping in all gears. It won't make any difference for 2nd or 3rd unless it's already slipping in those gears too.

And yes, the girls down this way are great. There's always a couple keen. ujelly?

Not jelly I have seen their standard and it ain't good.

Hmm well I'm to busy in those gears looking at the road to really tell but I dont think it does

If it's only just slipping in 4th then it's unlikely it's slipping in 2nd yet.

Yeah I know, they're generally all dirty little pregnant mall rats pinch.gif some good ones around to be found though, actually quite a few good lookers in my townhouse complex ;)

So this morning was rather chilly in Melbourne...I was driving to work and decided to see what 3rd gear could do with the freeway on-ramp - complete traction and no wheel spin this time? (Felt good!) What are the factors in this? Being colder than previous tests in 3rd, my car should be making more boost and power which generally equates to more wheelspin :/

The only thing I can put it down to is cold tyres having less pressure in them and offering me more traction...

Normally mine has less traction on cold mornings like today (cool weather, slightly wet road from dew or fog). Your tires probably had 3psi less in them so wouldn't think that was enough to affect it. Maybe just a nice piece of road.

Cant wait till I get my clutch fixed so I can see what the pull in 4th and 5th is like

That is where i think you will notice the biggest improvement. I went from around 220 to 255 and 0-100 really didn't change much (loss of traction in 2nd), 3rd was nice but shit 4th just pulled so hard and great watching the tacho and speedo moving together :)

Road surface as well.

Have you been able to spin it on this ramp before?

Maybe just a nice piece of road.[/size][/color]

It was an Eastlink on-ramp, so newish road surface I guess. It's always my "testing" on-ramp where I do rolling to 100 tests etc.

That is where i think you will notice the biggest improvement.

This...

4th above 100, now pulls like 3rd used to pull below 100 (@170rwkw) lol.

My current 0-100 has changed a lot compared to what it used to be.

Yeah from what it looked like on the dyno its going to be a very fun car to overtake with haha

3rd gear is so good at overtaking in the traffic, it's now my favourite gear! You don't have to drop a gear or thrash the engine to get anywhere with this turbo, it just feels unrestricted in the daily trafic. You would think the stock turbo is better down low becasue of it's response, but the SS1PU seems to give you a wider off boost range that is somehow more powerful (go figure). Off boost just doesn't feel like a laggy turbo car to me, it's almost as if the turbo is constantly making a tiny bit of boost all the time lol. Probably not far from the truth, because you can hear the turbo start spinning from way down low.

I'd honestly recommend the upgrade to anyone with an RB25DET powered daily, even if you don't want all the power. It just transforms the whole car into a much more capable daily driver.

+1 to this

Turbo is very very nice to drive off boost.

I drive to work each morning at 6am and have to baby it there because it's about 5min away.

Car feels amazing on and off boost

I've watched this thread quite closely over the last couple of years, and I am confident in saying you bought an excellent turbo. Whether it made 240 or 280rwkw it is what it is, theres no guarantee to a number with any turbo and plenty of people have strapped GT30s and struggled. That's just the way it is.

Your feedback is testament to the effort Stao has put into developing that unit, and anyone who has read the thread as thoroughly as I have would also know it is a great turbo. There is a reason I try to recommend the thing to people :)

If I was to do another RB25 the SS1PU would be my only option for a 240-270kw setup.

Just wait til I go E-flex boy!

I wonder if the FNT design has much to do with off boost being so driveable? Given it's a more efficient use of exhaust gases when you need them most, i.e. for the initial spool, perhaps it is helping out there? I imagine the bigger rear housing would make a difference over the standard housing too.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
