No there is no lag in the electric system. The eturbo spools up and reaches surging point straight way. The key to this is not all RPMs it needs torque. I'm looking to buy an higher powered motor soon. hopefully that can make 3~5psi. -
Yes I think I can get it to make 300rwkws+ on pump 98 with a GT35 rear and a large 76mm comp. I'm made 345rwkws at 28psi on that specification based on a R34 OP6 high flow based on pump 98. The stegea should manage similar, but its was pretty laggy.

2x Small 12s 5000mAh Li-po batteries each at the size of a Nokia 5110 phone weights about 1KG total. I'm thinking of series 2x 24V car batteries, that would provide lot longer running time.

Thats some Very valuable feed backs. I'm not sure how hard it is to get to the actuator, I normally insert a 2mm washer under it so it can preload the factory actuator a little bit as it is very soft to pull when it has no load. Try that it should make some differences in response, Also try a EBC if you can get one as that would stop the waste gate from opening early.

Did some testing with the electric turbo this afternoon. It registered 1psi on my boost gauge 2nd gear full throttle to red, with out it the car is always on vacuum to a maximum of -5psi at 7000RPMs 2nd gear, So if we count from where it was without the E turbo then it actually made +6 psi of boost. There is a noticeable gain in acceleration, and funny the BOV also operates as if there is a turbo, but nothing like having an actual turbo doing 20psi of boost. The skyline's got a reasonable size motor, I think it might be registering 2~3psi on a 1.5 or a 2L motor.

Further updates: This is a prototype turbocharger using billet wheel made for external gate use that I'm happy with its performance. It makes very solid power band with excellent response. I will refer to this prototype as the SS3-EG. It is now commercially available only in the form of external gate. Since no internal gate or bolton bits had to be made, I'm able to produce it at a low price of $1000 + tax or $1100 including, that is with the rear plate required for front making. This turbo is not made internally gated. It can only perform on a externally gated setup, preferably high mounted with a large 50mm gate using E85 fuel. Readings from earlier based on a side mount manifold with a 44mm external gate mounted to turbine housing on pump 98:

Was it done tonight with the gate controller? Any gain in boost or power? Regarding to the old massive supercharger running on 12V, it only made minor difference in the power curve through specific rpm range when batteries are fully charged. Its drawing way too much power and dangerous to operate. I've used a 600Amp switch to operate and it welded the switch together, it only came to a stop when the batteries were depleted. Those batteries were 2x huge Optima (biggest there is), they only lasted about 2 mints and was fully discharged. The gauge 0 cable connected to it were all melted from heat. Definitly not a toy I would install on any one else's cars.

Some updates regarding to the Electric turbo. lol. Now running duel roller bearing with 44V 6KW motor spooling up to 48000RPMs. Its makes very strong thrust. If i'm holding it on a skate board I'm pretty sure it will push me forward. Should've thought of making it into a back pack for a bicycle. Since its working I'll be testing it on E85 in about 2 weeks time.

Further update on the SS1PU Prototype: This is latest design using FNT .G3 turbine housing and I've trailed it with a SS1PU core. The aim is for better consistency as larger turbine housing don't creep as much heat. After tailing handful of different FNT nozzles arrangements, this one generated the best result. It has slightly more down low, same power but much heavier punch. I'll be using this on the G3 core next, and hopping to see 300rwkws on pump with much better response. This is also the first result based on my new Adaptronic plugin ECU, as I've removed the Nistune with Z32 AFM. Big thank to Trent contribution extra time getting every thing running 100%

Recirculating Bov Aftermarket Turbo Intake
hypergear replied to Marcus89's topic in Engines & Forced Induction
go to exhaust shop and get them to weld one up. Or check with M35 scotty or Abe on this forum. Or get a aftermarket BOV, then run 4inch metal induction pipe with a 4inch 45 degrees silicon hose. -
not planing to increase cost for the wastegate assembly. I've run that on 24psi most of time and there are no wear also did couple of 28psi runs. The thrust plate and collar are custom made with bigger bore.
-
The billet SS1PU core made 282rwkws on my Rb25det manual, E85 should bring up another 40kws. But I'm not sure how much power the Auto box and AWD would lose. So maybe 320rwkws? Sorry Scott I didn't fully understand the last bit. You mean you are welling to try a larger billet wheel? I can make that turbo a lot bigger then what it is. The standard version is $880 and the billet version is $200 more. Unless the car's going to be installed with supporting mods and be tuned for maximum power there isn't much of a need for the billet core.
-
Thanks for the input guys. There are two type of cores listed in this thread. The one with the billet wheel is the SS1PU core, and the other is the ATR43G2 core. Both cores has the exact same turbine setup. The SS1PU billet core is on the larger side and has produce a maximum of 282rwkws on my test car. Since it has a more efficient compressor wheel it is capable of producing greater flow, that could possibly be the cause for the boost creep using the OEM waste gate setup. This is the first SS1PU core that went into the M35 OEM housings, I will take note to replace the OEM waste gate assembly when it is used again. The ATR43G2 core is on the smaller side and that was capable of making a maximum of 260rwkws on my test car. The M35 that I've road tested it on did not show signs of spiking. A larger 36mm waste gate assembly using a 32mm internal gate will be fitted for all further M35 OEM turbo high flows services.

I was epaed long time ago on my sil180 the last time was due to a high mount manifold so I could change turbo easy on it. That came with a pretty heavy fin. The skyline with the stock manifold and internal gated turbo has not been epaed, it has been defected how wver it was for none secured power steering bottle. In this case might have to drive the car to Trent with no waste gate.
-
Here's the copy from Scotty's customer. This turbo was made as a bolton high flow using stock housings. The actual SS1PU run a .60 comp and .84 rear which is bigger in A/R compare to OEM M35 housings so the end result could be better. How ever VQ25 is a totally different class of engine plus the Auto trans they are not the same to our Manual RB25dets. I'm also in the process of adapting that TD06SL2 billet 20G, how ever I'm a repeat offender to EPA and has been fined a large sum of money in the past for not obeying EPA modification guides. Knowing the next fine would be extremely high, this is a major concern. There is ambiguous statement listed in EPA's guide such as: External gates are not allowed, and all exhausted gas must filter through a catalytically converter. So by word "external" stands for bleeding into environment without filter through the cat, then plumbed back would be considered as "internal" gate? Or if I add a 2inches muffler plus a small cat into the screamer pipe would also make that Internal and street legal? comments from any one's been dealt with those matters with EPA earlier would be appreciated. Thanks.

Those wastegate studs you are inserting will reduce the area of the wastegate making boost creep uptop same as if you've got an wastegate that is too small. Except the extend of creep is fully controllable. Insert a stud at once. Method is debatably but I've used it quite often at trents and it appears to be working well. Also an update. This is the very first billet SS1PU core that we high flowed into a M35 Stega's OEM turbo for a Scotty's customers. The car made 300rwkws on the auto with E85 at about 20psi of boost. I'll still need to take acount in modifying the OEM wastegate assebly on those for better boost control using this core. Will upload dynosheet later.
-
After I high flow it yes. And possily mush more. As it is probably not, but close.
-
Its a turbo off the vg30et from some old 300zx. Note some of them were also fitted with a t3 vlt turbo.
-
Another good result from Toshi. The power figure is good, check the actuator reload, it appears if the gate is not 100% sealed, you can find instructions on actuator pre-loading under my youtube account: taosg2001 This is an easy operation that can be done with the turbo still attached. Once gate is sealed and loaded, the car will be able to gain much more response and mid range power.
-
Toshi it will he good if you can explain the method (doesn't have to he in great detail) about how you can make 260rwkws on a stocky high flow and factory injectors and why most other tuners are straggling to pass 230rwkws.
-
Toshi mentioned some thing to spool turbo without fuel to increase power. I don't deny or fully understand his concept but the results are extremely tempting. I guys it would be good of toshi can enter some input.
-
After going through all the trouble modifying my CA18det into 316rwkws region I think the Rb25det is hell of an excellent engine .
-
Standard high flow would be suitable for your applications. I'm generally seeing around 240rwkws with option, how ever I'm recently seening some 260rwkws results based on 15psi from Toshi's remaps using stock injectors, afm and ecu. So for your goal, get the standard high flow, then pm toshi for ecu flash and that should archeive it.
-
This assembly should have some effects, With the device engaged the turbo gains faster response how ever the engine pins up top, with it disengaged the motor picks up 8 degrees of timing up top but loses big chunk of power band down low. So I want it to be engaged till about 20psi then slowly released after that point to gain the top end timing. That way we should have fat power band from start to end.
-
depending on how much problems I might encounter. would be couple of month at least.
