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?
