Trozzle Posted December 18, 2012 Share Posted December 18, 2012 Yeah as above, it depends on the cams. For all intents and purposes, as far as you're concerned you won't lose VCT. I don't think there's any point whatsoever putting any cams in the RB25 for testing purposes that don't retain VCT. 256deg Tomei poncams seem to be the best and most common cam upgrade for mild/street RB25s, and I believe they retain VCT. Not NEEDED, but they fatten up the midrange.

hypergear Posted December 19, 2012 Author Share Posted December 19, 2012 Got the Fnt turbine ended T67 dummy fitted today, and went for a little test cruise with my current SS2 tune. I personally recon its pretty laggy for every day road use. It does have very decent top end, but its down in power and torque mid range. on 22psi In 3rd foot to floor its starts to pull really hard from 4500RPMs all the way to 7200 limiter. With limiter at 8500RPMs on tracks its probably alright, I think I will be seeing close to 400rwkws on my next tune. Since the the FNT housing is in .82, the smaller 10cm turbine might produce better response. I got a overlay print on my final SS2 run, This graph explains about the missing mid range very well. Blue is my last .70 SS2 bush bearing high mount Ex Gate Red is .60 SS2 Ceramic roller bearing ported stock manifold internally gated Pink and orange is 10CM T67 on high mount Ex Gated All running E85 Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/338/#findComment-6674063 Share on other sites More sharing options...

petero'nell Posted December 19, 2012 Share Posted December 19, 2012 Seems to be what most people are getting out of E85 from the dynosheet section, even Simon's T67's not showing true potential till 7000RPMs+, there is no match in mid range power and torque to SS2.

hypergear Posted December 19, 2012 Author Share Posted December 19, 2012 Tao, u change turbo's every week Yes, and high mount made it easier, all back to the SS2 now . I should be hitting up strips more often. Most of customers are using it for road, I would prefer turbos with very good power and torque within usable rev range on stock cams and cam gears. Making the external gate billet SS1 and SS1.5 at moment. They should be super duper responsive on road. 2ndly do you guys get up really early or never to go bed at all?

Josh_TypeX Posted December 20, 2012 Share Posted December 20, 2012 That is my T67 result, and yes it is on E85. I am running a Greddy style plenum which on all accounts results in a loss of torque. But that SS2 really does look amazing. 600Nm from an RB25 is insane.

No I dream about hot chicks licking my turbos Hey stao, just out of interest; how much would it cost to convert my ATR43G3 nissan 6 bolt internal gater to this current SS2 nissan 6 bolt internal gater? To do that we need to: Sleeve and re-profile the comp housing and back plate: $150 Compressor wheel: $200 Balance & Assembly the CHRA assembly then the turbo assembly.: $70 Total: $420 It will becomes a SS2 in .70 comp housing used on the test car with Nissan IW assembly. It won't be able to unleash its full potential till fitted with a proper exhaust manifold and externally gated plus a good tuner of course.

LANDSCRIBBLE Posted December 20, 2012 Share Posted December 20, 2012 Ok thanks. Was just curious. Im still happy with the G3, just waiting another few weeks until i get a tune with 20psi on this rebuilt motor.

hypergear Posted December 20, 2012 Author Share Posted December 20, 2012 Some updates on the new billet SS1 and SS1.5: I've had both housings machined to suit the core. They will be using a SS1PU's externally gated turbine with 3inch outlet. This housing was customized to suit my current front pipe that was made for the SS2, so looks bad after been chopped and welded it few times but I got it fit on the end. All fitted up and ready to go. will do some road tests tomorrow.

hypergear Posted December 21, 2012 Author Share Posted December 21, 2012 Well I can't really do much till its tuned. This turbo has a totally different rear wheel and housing compare to the SS2 so I'm not very confident flooring it at this point. How ever I did let it on 12psi external gate pressure and its very responsive and probably due to the effect of the external gate and manifold the torque was incredible. Driving wise it feels like having a R34 turbo on a R33, turbo comes a live with just a little bit of throttle, ie tap 20% throttle and the turbo whistles to boost, floor it = a very big pull. There are generally two kinds of feed backs, its either this car's got some serious power or this car is very fast. I think All SS1xx series belongs to the 2nd category. I've swapped the SS2 back on so I can drive the car, will post results for all turbos once Trent gets back from overseas. at moment I'm modifying the 10cm turbine housing to suit my front pipe, be interested to find out the on road behavior of my billet SL2 20G and 25G on Rb25det.
