Hypergear Turbochargers and High flow Services Development thread

thanks! price?

Super keen on the results of that super T3 turbo.

Just incase... you know. Upgrades.

[Komdotkom]

The SS15 high flow would work extremely well, Will be suited between 200~230rwkws region:

I can confirm this, I've got one on my tarmac rally car it's fantastic. Topped out at 220kw@20psi but the boost response is fantastic.

That looks nice...what are you going to call it?

cheers

Got dyno graph?

[Komdotkom]

Got dyno graph?

Sorry mate, no graph. I could probably find the boost vs rpm data from the Motec if you want to have a look at manifold pressure at a given RPM

[wildeagle44]

Any news on the rediculous spooling ss2?

I guess we can call the new turbo ATR45.5SAT model. I'm keen to see the result.

The Yellow R34 No.2 didn't go so well unfortunately, and we had to sort out a bunch of little problems with installation as well as getting the car running properly, there is still issues on ECU communicating with the boost solenoid, we run out time and have to finish off the tune another day.

But yes it is very responsive, notice the linear power and torque before 3000RPM:

2ndly, because I'm now using a JJR's normal front mount cooler kit instead of the return flow. Boost shoot easily over 20psi. I'm sure that 90 degrees bend would be cause of the boost tapper on earlier runs.

But either way, special application turbo for return flow cooled RB25dets are available.

best boost graph ever

[Kinks]

Agreed, that boost graph is amazing.

"How much boost does it make?"

"Yes"

[jet_r31]

lol , looks like mr .squiggle drew it..

cheers

yea this car's the worst out of all, still alot of little stuff to fix, while I've already made the next booking sitting around for 40 mints, next tune is booked 3 weeks away. hopefully all sorted by then.

[Kinks]

Looks like a very impressive turbo Stao.. Early boost is great for the street, feels like a bigger motor and no need to swap gears to tackle a hill.

[Leroy Peterson]

just tell everyone the turbo comes with VTEC. that high-rpm boost kick.

[dori34]

any ideas why my boost would fluctuate from 15-17 psi back and forth?

changed to a 15psi actuator and this started happening, should i add more or less preload?

previous actuator did not have this issue.

no boost controller installed, running gate pressure

[hypergear]

updating some 1JZ results. Those are from 1JZGTE Chasers:

This is 292rwkws on 19psi on our TD06SL205 Turbocharger externally gated, P98 fuel, Unopened engine:

And this is using a high flowed factory CT15B on E85 fuel making 321rwkws.

[jet_r31]

Are they both results from s.a stao?

Top one is definitly is and the bottom one looks like a graham west tune

cheers

Little update. The R34's definitely not going as smooth as any of the other cars I've modified. The new car's finally made it self all working today on the dyno. It hits a boost restriction which boost curve went flat at 19psi on 90% ebc duty, how ever the pressure before intercooler is showing a boost curve that kept on clamming all the way up to 24psi.

After setting EBC on 100% duty after 4000RPM, and there is still a 4psi pressure drop. Didn't got up to expectations but definitely better then the 9psi drop that I've had with the return flow kit. Its currently using a 600x300x68mm Takashi cooler, I will be upgrading it to 600x300x100mm and hopefully reduces the percentage of pressure drop.

I have never experienced similar issues on my R33, S14 or the R33-GTR, but to both of my R34s.

That R34 made 425rwkws earlier did not have this issue however, by using a RB26 inlet manifold. I'm unsure if it is related to the actual design of the inlet manifold, if so I might have to make a group of special application turbos just for R34s.

Power stays 267rwkws @ 20psi, basically made no differences apart from lag using a much larger turbo.

Boost curve before cooler (20psi) and after throttle body (24psi) at 100% EBC duty

Hmmm....interesting. I've got your ATR43 G4 going on my NEO in the next few weeks. Will be interesting to see if I suffer similar issues.

[hypergear]

Add a vacuum nipple before the cooler and compare boost reading to whats in the inlet manifold. Hopefully yours will match.
