Hypergear Turbochargers and High flow Services Development thread

lol ramps a little steep, 150-330kw in 700rpm

He explained why that is. It's a 9 second ramp as he is concerned about the stock internals holding up to such huge power.

It would make for an interesting drive, however :)

Wouldn't a shorter ramp actually make it look laggier on paper since the dunno allows the rpm to climb faster?

yes Trent wasn't very confident with stock con-rods when we got to around 375rwkws, faster ramp puts less load on to the engine, and generally result that sort of power curve. I was hopping for 400rwkws at the time ;) .

On road its obviously not as responsive as the SS1PU or the SS2, but pulls crazy after 4G on full throttle. I'm putting the SS2 back on for the final tune based on external gated setup and e85.

The turbine housing used on that run is a .82 type B rear. I believe type A would have produced more power. How ever this is the first prototype that made into this sort of power range, so there are many areas that could be twicked for even better result.

I think G3 will max out around the 370rwkws mark based on the same setup. I will do a test based on it in the next few weeks. I've also got few idea on high flowing factory R33 and R34 turbos that I like to trail.

Further evaluation on the SS2. it made 337rwkws on e85 externally gated at 18psi peek just touching 20psi. I've also trailed it based on internal gate running boost controller and straight off the actuator.

The solid red and green are from internal gate, Green is internal wastegate pressure:

Boost curve for all runs.

My ss2 internal gate turbo is ready to be picked up tomorrow.

Going to installed on a healthy rb25neo, ID 1000 injectors, z32afm, Hybrid turnflow intercooler with one of Scotty's metal intakes.

Will be tuned by Trent at Chequered tunning.

Will post up results when everything installed. Probably sometime in the next month

Ooo, nice one Tony. e85 I hope?

Nah not e85. It's my daily and I do alot of road trips on weekends.

So don't like the idea carrying jerry cans in the boot everytime I need to travel.

But yeah ID 1000 injectors just in case I ever change my mind in the future :P

It would be interesting to see what your G3 style hi-flow(PU?) did on a stock exhaust manifold and E85,

eg ..most power for a full stocky look

cheers

hypergear can machine the stock rb t3 inlet cover to match up and bolt onto the ss series of turbos which means stock looking turbo

Yes can run stock comp housings on those.

Some updates with factory exhaust manifold fabrications. Well yes it is a not an welly engineered part. The port don't match up with the head as we already known, they had huge lumps in side the collectors, looks like they were trying to seal the bolt holes when the bolts aren't fastened. The lump took almost 40% of the total volume area that merged cyc 4 5 6. That really explains why its always the last few cycs that blows up when ever is an engine failure.

This is what they are like now, with the top half milled, lumps cleared out, and I'm going to weld steam pipe over the top to increase the overall volume of the manifold log.

Very nice, photos really help show the progress your making :)

Will these be done on an exchange basis or will you have stock?

    • Hi all, I need to get this HKS SLD attached to my stock ECU because I've now got the German autobahn and faster European circuits to contend with.  The car is a manual 2dr ER34 with an AT ECU and I've realised the AT ECU has two pins for speed sensor signals: Pin 29: Vehicle speed sensor signal (Vehicle speed sensor 2) Pin *58: Output shaft rotation sensor signal (Vehicle speed sensor 1) - *RB25DET A/T model only Before I go butchering this harness, is anyone sure of which pin is the correct one for signal adjustment? The attached document from HKS indicates pin 29 but I found this situation mentioned in the following thread on a different forum (R34 GTT Auto Trans Speed Cut Problem | Zerotohundred) mentioning pin 58 needing to be altered by member zephuros, albeit it seems to be for an RSM-GP and the info appears to be old.  R34_All_Workshop_Manual-pages-2.pdf R34_All_Workshop_Manual-pages-3.pdf R34_All_Workshop_Manual-pages-1.pdf HKS SLD Vehicle Pin out P59-P70 ER34-pages.pdf

    • What is the "compromise" that you think will happen? Are you thinking that something will get damaged? The only things you have to be concerned about with spherical jointed suspension arms are; Arguments with the constabulary wrt their legality (they are likely to be illegal for road use without an engineering certificatation, and that may not be possible to obtain). A lot more NVH transmitted through to the passengers (which is hardly a concern for those with a preference for good handling, anyway). Greatly increased inspection and maintenance requirements (see above points, both).   It is extremely necessary to ask what car you are talking about. Your discussion on strut tops, for example, would be completely wrong for an R chassis, but be correct for an S chassis. R32s have specific problems that R33/4 do not have. Etc. I have hardened rubber bushes on upper rear control arms and traction rods. Adjustable length so as to be able to set both camber and bump steer. You cannot contemplate doing just the control arms and not the traction arms. And whatever bushing you have in one you should have in the other so that they have similar characteristics. Otherwise you can get increased oddness of behaviour as one bushing flexes and the other doesn't, changing the alignment between them. I have stock lower rear arms with urethane bushes. I may make changes here, these are are driven by the R32's geometry problems, so I won't discuss them here unless it proves necessary. I have spherical joints in the front caster rods. I have experienced absolutely no negatives and only positives from doing so. They are massively better than any other option. I have sphericals in the FUCAs, but this is driven largely by the (again) R32 specific problems with the motion of those arms. I just have to deal with the increased maintenance required. Given how much better the front end behaves with the sphericals in there.....I'd probably be tempted to go away from my preference (which is not to have sphericals on a road car, for 2 of the 3 reasons in the bulleted list above), just to gain those improvements. And so my preference for not using sphericals (in general) on a road car should be obvious. I use them judiciously, though, as required to solve particular problems.
