Different profiled wheel blades, also complete with a bigger turbine housing. I've made one more billet wheel with minor alterations to the hub that I like to get some result off. -
same turbo just pump 98 internally gated. Only shows bit more responsive on paper, but on road its very different to the G2.5. Further response gain will cost top end power unless going external gate. How ever small differences do adds making a pretty big difference looking back to the old G3. So just have to keep on working at it.

Results from the newer SS2 prototype on Pump 98 internally gated in bolt form. It made final of 302rwkws and did actually manage 200rwkws by 4000RPMs. Pretty sweet to drive on road. At this stage that every HP its getting is based on a trade off of some response. Probably only a tinny bit more room to play with. I will trail one more wheel on it in about a week time.
-
I actually mean 4inch front pipe as in from turbo to the cat, I will get a custom 4inch exhaust made up as well. So basically the full bolton kit including: Intake pipe, turbo, manifold, external gate, and full exhaust. I will see if I can make a heat shield that hides most of the stuff.
-
Its going to make a differences compare to stock manifold on internal gate, you usually find a responsive externally gated turbo perform poorly running internally gated as the combination of the charger is different. For a internally gated turbo to keep on making power the EGT has to stay low, which the only way for it to happen is go larger in turbine housing or a more free flow turbine wheel, then compensate response with a lite weight, small but very efficient compressor. I will be concentrating in up to 300rwkws pump 98 bolton turbos and probably up to 350rwkws external setups. I'm in the process of making a full bolton kit including manifold, gate, turbo and full 4 inch front pipe with Brea Autos. And will post of what we can come up with.

thought about it. Ordering couple hopefully this week. How ever back pressure between setup varies, So it would be ideal been able to adjust the spring load freely referring to each and every setups. I will put some thoughts into making it.

Running rich blown black smoke and misfiring is not the definition of turbo surge. You've already explained your self the reason for heat soak in your previous posts. Deposit means you are getting that money back after receiving your current turbocharger, just a way giving your self convenience for not taking the car off road. You are experiencing problems I and others never experienced, if same problem persist on the new charger while others made positive gain then just confirms what ever issue you have has nothing to do with the turbocharger, regardless of the choice of the turbocharger. Then you need to sort out what ever problem there is and repair it before selling the car. I have a OP6 high flowed turbocharger that produced result of below based from a customer's R34 sent in by the customer: Numerous other customers are getting similar results based on this high flow profile. Does that looks reasonable enough to you? If you wish to swap, please act now.
-
lol perhaps we also get blamed when your A/C don't work up or car radio stops functioning. You are putting meanings on names and blame the turbocharger for totally isolated problems. By reading your post there are many section of the car not sound, even with every one's advise, things are merely done. I've been offering a free turbo swap to a popular model since last Oct on numerous occasions with what ever methods reasonable, there has always been reasons for not doing so. and there is nothing more I can do. If there is a genuine believe of a part that is not functioning correctly, a normal person would organizes warranty or replacement with vendor. Nothing happens If you persist or reluctant doing so.

I've converted last run into actual torque based on the traction effort listed on the reading. the new SS1PU is also built, hopefully due in for a tune next week. The current agenda still lays on the design of the actuator and waste gate package, as I'm hopping it holding 20psi flat internally gated. Likely will need designing and making of a new CNC billet actuator some how allowing spring tension adjustments like few of the external wastegates in the market. Since many recent results from Status were done on e85, I will likely be running the same fuel for the coming tests making the result comparable. Having said that, I will get some 98 runs done on same or different dates, depending on their time allocation.

This is a larger all around turbo compare to the older SS2, how ever does not feel laggier, with a much stronger punch, how ever it could be the E70 that I'm using. E85 is much cleaner fuel, about half of my customers are running / going to run on that fuel system, pump 98 is starting to be a thing of the past. Plus all major car firms are introducing E85 powered cars, so the fuel should soon be available to all states. Compare to the G2.5 chart, the SS2 shifted the whole power band left by roughly 200RPMs, using 98 it should make just 300rwkws with 200rwkws by 4000RPMs. E70 doesn't appears to make turbos built based in the type B .82 housings any more responsively then pump 98 apart from the top. So what's likely to change is the power band after the turbo hitting full boost, then we can then apply the -40kws peak power rule to calculate the estimate power level of 98 based on E70 result. The earth quake freaked me abit. I was with a customer whom's here collecting his rebuilt XR6 turbo. When striked, the whole factory walls vibrated for couple of secs. Funny that guy was like: "Arrhh, strong wind, shit weather."

did any one else felt an earth quake around the campbellfield area or is it just me?

Rb25 Turbo Upgrade, All Dyno Results
hypergear replied to Nacho Vidal's topic in Engines & Forced Induction
93 model R33 GTST Forgied CP pistons, valve springs and stock every thing else. 800cc injectors 600x300x75mm Front mounted cooler Xforce 3inch turbo back exhaust Profect B electric boost controller Brea bolton manifold. ATR43SS2 light weight alloy billet comp wheel, .82B rear / .60 comp. 14psi actuator, internally gated. 4inch intake pipe Adaptronic Plugin Greedy EBC E70 fuel 345rwkws @ 19psi bleeding down from 22psi. Fuel pump maxed out. -
There was only enough time for a touch up today. I will do 98 run when I get the fuel pump replaced. Here are some video footages taken from today. Note the difference in sound between the light weight billet comp wheel to the traditional cast and 7075 billet wheel. It came in very early, how ever on paper it doesn't show much.
-
Some result from the new SS2, only had time to do a touch up on my E70 tune and my fuel pump is at its limit. I will need a bigger pump for the E70 to finish off the power run in couple of weeks time. For time been it made 345rwkws at 19psi bleeding down from 22psi. Likely there is another 15KWs gain using a high pressured actuator holding 20psi up top with more fuel. It is currently running the lever mode with a 14psi actuator. For some reason the lighter material did not alter much in boost response on paper, how ever managed to produce heaps more mid range in comparison to the G2.5 that made similar power output. The difference is very noticeable on road, does not feel laggy at all. The prediction on pump 98 would be around the 285~300rwkws mark as the capacity of the Type B .82 rear housing is up to the 300rwkws mark.
-
Only the new SS2 if works well, you are welcome to send in yours for update free. SS1PU is probably in about a week time, running the comp wheel machined using the same material. I will also be doing lot of tuning and work for the turbo kia project.
-
Trent's tuning it on Monday. Likely I will be keeping it on E85, possibly few runs on 98 depending on how the time goes.
-
Some updates: I've finally managed to start the car, for some reason it was much harder to get the E85 started when the weather is cold. It is other wise in a worm day. unfortunately this years Melbourne winter is pretty cold. The new turbo using less weighted material driven nicely and responsively on road with the G2.5 tune, with plenty of 3rd gear wheel spinning action. I believe this is the most responsive turbo using .82 type B turbine housing internally gated so far. Hopefully producing similar power as the G2.5 while providing SS1PU's response. Interestingly or not, E85 appeared to be a much cleaner fuel then 98. I have taken some photos from the G2.5's rear housing and turbine shaft when it was re-made into the current SS2. They are clean, while 98 would leave a firm layer of black carbon. Note: The black mark on the turbine wheel is carbon mark. No one will ever get a cracked turbine wheel from here.
-
Its too expansive to build plus not much difference in performance. So I will leave that project for the time been. Status is getting their dyno fixed today, so assume every thing goes well, I should have some results from the new SS2 turbo on monday.
-
Hi Man. Your turbo has been high flowed except I had no address of where to sending it back. I made a post about it in my thread earlier. Please check PM.
-
Still the paper weight one, its going to the dyno hopefully next week.
-
just type in the word: "trail" for all prompt boxes. and it allows you to run it once. Then you will need to uninstall then reinstall it o run it again with the same word.
-
Its been made 4inches for a reason. Best to have a 4inch intake pipe. Also I've got a R33 turbo sent in for high flowing about week ago, job is complete, but it has no name or return address on it. Please pm through if that belongs to you.
-
mm I think that was optional. he's user id is Abe2 send him an email. Or see if ScottyM35 have some thing invented.
-
This is a high flow that I've done for a set of Toyota supra with the SS1.5 CHRA. Come out pretty good. photos: By specifications those two should be enough to flow 500rwkw+. Will post results once the customer get his car tuned. Also this are stainless steel 3inch metal induction pipe made by Abe for R32/R33/R34 high flowed turbochargers. RRP is $200, or $150 with any turbocharger services purchased. PM if any one's interested.

"vague" is a defensive word. To me it means no differ. because we live in a civilized society, no one has physical rights to stop any one else from using other people's idea, we can only ask for remedies. So question is, is "copy right law" actually protecting you, or only protect you interest when you have a million dollars to sue. How is the court going to weigh up of protect you (as a little guy runs a workshop in this instance) or protecting on the billion dollars of tax revenue generated by those firms that "copy" his ideas. This is off topic. But it is every developer's concern.
