Hypergear Turbochargers and High flow Services Development thread

[hy_rpm]

Most i seen was 266kw from my car 25psi dropping e85 and that was with the larger rear housing .86
Stock bottom end sr but
I would reccomend going the atr28ss2 in bb with .64 rear housing more responsive due to the smaller rear and i made 280kw with this
On a built motor with larger cams and custom exhaust manifold i would see it making 300kw

[hypergear]

Action Dan: Yes. the factory exhaust manifold is a restriction and SR needs cams to make power. Plus your usual free flow FMIC, induction and exhaust.

and what if the goal was morel like 350? and it could go on a full Ts manifold and had a good head supporting it? 

[hy_rpm]

If going high mount atr43sat bb

[No Crust Racing]

Come in T4 and Twin Scroll? What's response on it like?

[hy_rpm]

Ask tao im sure he can arrange that
Most results ar from rbs but usually all in by 4000rpm and there only running t3 single scroll
Twinscroll will help alot hence why evos get away with 300kw turbos but are still responsive

[hy_rpm]

It actually makes 317rwkw on 21psi by 3550rpm on his test r34
Thats on 98octane fuel

Juicy

This particular SR20det engine is something built by forcedmotor works 4 years ago. It run one of our ATR45SAT turbo compete and won WTAC Open class in 2016 and is still a current world record holder of the fastest SR on Wakefield. Its on a single T3 scroll manifold running external gate, and that pumped 400rwkws on E85 fuel, 28psi by 4250RPM. Far as I know its just a standard rebuild, no VCT with forged pistons with 264  / 256 Tomei Pro cams. For around 350rwkws mark I will be recommending this turbocharger.

Some results to share, This time is from Justin's drift car running with one of our ATR45SAT ceramic ball bearing turbocharger. 

R33 GTST unopened engine.

HyperGear Atr45SAT Ceramic ball bearing turbo

6 boost manifold

Turbosmart 45mm Gate

Ebay 600x300x100 Cooler

ID 1000cc Injectors

460 lph Fuel Pump

3 inches turbo back exhaust

Haltech ECU

E85 fuel

Car made 397rwkws @ 21psi on a conservative tune for stock engine. Should see 420rwkws at full potential. 

 

[32psi]

Is the head standard on that engine?

[hypergear]

Engine is fully standard at current stage. 

[No Crust Racing]

How do you think that would go on an SR20 with a really good head and twin scroll manifold? 

[hypergear]

Assume its on a welly built SR with a good free flow setup, you will match result of Top stages S14 listed above. 

[Robzilla32]

Do it. Do it. Do it.

What would you recommend for a daily driven rb20

Looking for around 220ish kws, response and internal gated?

With normal mods

nistune, EBC, cooler, fuel pump etc

[hypergear]

I would high flow the factory turbocharger using a ball bearing core with a G2 or a SS15 profiled wheel sets. the SS15 is a better choice for power and response. 

[Adz2332]

What would that be worth

[Adz2332]

And a 20 turbo or 25 as I have both

[hypergear]

For the best result use an Rb25det turbo. For a Ball bearing, billet wheel Ss15 profiled highflow looking at $1500 to complete including oil line.
