Your car is pretty quiet in comparison

Can't hear the Stututututu either

Result sent in by one of our high flowed 21U R33 turbocharger's customer. Car made 271rwkws @ 19psi P98 fuel, Vs an Ebay purchased high flow replacement.

Result sent in by one of our high flowed 21U R33 turbocharger's customer. Car made 271rwkws @ 19psi P98 fuel, Vs an Ebay purchased high flow replacement.

Is this on an r33 or r34?

For the same given setup, will the neo make more power or are they same same?

[hypergear]

R33 GTST. The ebay high flow failed and it was brought high flowed for the 2nd time. No hardware apart from the turbo has been changed.

jesus the gain is crazy good, good stuff

More result from our 21U G3 profiled turbocharger, 312rwkws @ 19psi. E85 fuel.

Made 312rwkw and 474nm. The video above isn't working properly when I tried watching, here it is again. Thanks for the turbo Tao. Im extremely happy with the result.

 

Tuned at VIC DYNO HIRE.

That's mental.  Got a pic of the graph?

That's mental.  Got a pic of the graph?

I do but on that run, unfortunately the tune did not have additional timing before 5000rpm. We did the power runs first as we where running out of e85 in the tank and then added the low end timing afterwards. Tuner wanted to do a final power run but I didn't want to risk it sucking some air. I also had a boost control issue, full boost should be at 3.4k but isn't arriving till 3.7k. Still trying to work out the issue there, lack of time to troubleshoot. It didn't effect top end but mid range is below what it should be. The graph shows 150rwkw at 4k, i estimate it would be around 170-180 with the extra timing but should really be closer to 190-200rwkw if the boost issue is sorted. Anyway here's the graph and yeah the car feels pretty mental with this sort of power and I'm very impressed and happy with the hypergear 21u high flow.

Tuner emailed me some better images of dyno graph today. The second graph is a comparison of a run with no additional timing and boost controller off. I think a proper intercooler and exhaust would definitely improve the midrange and overall torque output. These images are much clearer at least.

Updating with two more results: 

 ATR43G3SAT externally gated on E85 fuel, stock engine with supporting mods

Awesome drifting video from this car. Can anyone please advise of how to insert Youtube media into post please (like dyno run video above).

Also pretty decent power on P98 fuel. Running off an Rb30det with 264 / 272 cams using one of our custom made ATR45 turbochargers.

This is quite interesting of a job so I post. It is high flowing and converting a bush bearing BorgWarner S300 series Turbochargers to ceramic ball bearings. ATR45SS compressor is used with a matching .70 compressor housing along with original S300 turbine wheel and housing.

How much would that cost and is there much benefit? Also can you do it with different comp covers?

[hypergear]

BB improves throttle response and maximises boost response, so the turbo makes more boost with lower rpm. Yes can use different housings depending on size of wheel used.

There is about 6 hours of engineering work required making up all the little collars, spacers, as well as modifying the bearing housing and re-grind the shaft, everything needs to be done perfect for this to work, its not a quick easy job.

This particular one cost $1400 to do thats including the BB upgrade as well the supplying the comp wheel and comp housing.

For a Normal Garrett T3x and T4x  based turbocharger in working condition with housings supplied, it will cost $650 to carry out. 

Holset or BW medium / large frame like the one above again in working condition with housings supplied will cost $1000 to carry out.

[Griffin]

Ok thanks for the response. 

[hypergear]

Some more data to update with. This is an result of an compressor wheel upgraded of a TD06L2 12cm based 20G P98 fuel to our ATR43SAT compressor wheel.

Is that on a RB30?

[hypergear]

Yes its a RB30det on P98 fuel externally gated.

[hypergear]

I will keep this thread synchronized with our FB updates.

This is based on an prototype SS2 running ceramic ball bearing core. The new housing has been shorted so the dump pipe is no longer been pushed back against the A/C drain. Turbocharger made 302rwkws @ 21psi P98 fuel internally gated as a bolton turbo. Currently 18kws short of the target goal. Project is still under development.

Hey Hypergear 

Wondering what you think one of your 21U high flows would work like on an FJ20 4 Cylinder 

I'm looking to keep the stock T3 manifold as it's an engineered car, hoping to make a responsive 220ish kws on 98

Any help would be great thanks
