Another result to share, this time from one of our high flowed R33 GTST 21U Turbochargers externally gated on a built  Rb25det engine. Car made a super responsive of 330rwkws @20psi on E85. Full boost by 3500RPM with very wide power band. 


Forged R33 Rb25det engine, ported engine head.
HyperGear High flowed R33 GTST turbocharger
SpeedTek exhaust manifold
Turbosmart 45mm external gate
ID2200 Injectors + Twin Bosche 044 pump
Programmable ecu
3 inches turbo back exhaust
Tuned at Chequered Tuning

Looking forward to see it perform at Vic drift Round 3.

I did some SR stuff in 2014. if you go back to page 456 and read from there, that contain alots of SR20det's developments. On page 1, search SR20, and I have listed pages that contain SR20dets developments and results.

Just road tuned my R33 with an ATR45SS. Pulls pretty damn well at 16psi. Z32 MAF shows 4.77v at that boost and the 875cc injectors are at 60%. All on 98RON. I have a walbro 485 pump ready to go in for when i decide to go E85.

Great videos to shared from VicDrift website. I've seen few of customers cars made to the final battles. That is Cam Martin's silver R33 GTST running our high flowed 21U factory turbocharger making 330rwkws, White R31 Wagon using one of our ATR43G3SAT CBB turbocharger making 310rwkws and Just Gurener's purple R33 running one of our ATR45SAT CBB turbocharger making 400rwkws. 

Are there any results for the ATR45SS on an RB? I'm tossing up between the ATR45 CBB and ATR45SS CBB. Tao what would be the expected difference in lag and power be between the two? Both external gate on a proper manifold on a 30DET.
Hi Xr pilot. I recently installed one of hypergears atr45 .82 billets on my rb30det. Stock block stock head stock cams etc. On bp98. Had a waste gate issue which lost alot of mid range power and torque but still managed 375kw. E85 would see a great improvement over 98 also. I have uploaded a graph from my run. Keep in mind this is with no vct so there is alot left in it. Also rev limiter was set to 7000rpm because of stock motor. Graph shows that extra revs more power is easily do able. Trent from chequred said it was hard to stop it making power at 7000rpm as it just wanted to keep climbing. Hope this helps. 20180327_225537.jpg

Overall a decent result.

Be interesting to see the boost curve with this one.

I'd say that no VCT is a big cause of the relative torque deficit across the 2500-4500 range.

Torque peaks at 5500 then starts dropping, so power has peaked before 7000. Not sure why the tuner says it will make more hp with more rpm.

Hope he pointed to the saw-tooth shape of the graph over 5000.  Might be worth investigating timing scatter, see if that needs to be addressed.  Not uncommon to pick up 10-15kW by fixing those issues.

Saw-tooth area is just topical hub dyno being sensitive to any reactions. Every hub dyno graph iv seen all have it from various tuners. There is next to no timing up top from what I was told as it was having an issue with creating boost when timing was added up top. As already having a huge boost creep issue already it was left at that. Cam duration is most likely also an issue on the torque side as there just stock cams from a r32 s0 rb25 so exhaust cam lift is actually smaller then stock rb20 which are tiny already.

Colour me befuddled.  What use is a power curve that looks like that?

That would be the result of the loose converter, so it’s not real. No way would that be of any use if the car was a manual.

As mentioned that's an result of high stall auto. this car run 9.9sec quarters on 578rwkws with similar power curve using an BW S400.  It would be useless if that is an manual curve.

This might be interesting. our TD06SL205 in 10CM running against a 2018 model Ebay (Not kando but a someone sales rather similar) Billet 25G TD06 10CM. Ebay turbo lasted few dyno runs before running into issues and the owner decided to do a core change so he can completes the dyno tune.

I don't think ban and block buyers for warranty claim is a good business practice,  having a pissed customer is at least, most importantly the data of why and where a product can be improved is lost.

Green is our TD06SL205 and Red is Ebay

This is fantastic data mate! Would be a much faster car with your turbo compared to the eBay setup.

    • 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"
