Hypergear Turbochargers and High flow Services Development thread

[GTSBoy]

Gtsboy youre from sa yeah? I may know of one of those guys you are talking about.

He will most likely be doing my heads

I'm guessing TK. If so, good choice. He and I have fought like cats and dogs over minor technical points because we speak completely different languages for the exact same stuff. But there is no arguing about his capability.

[zebra]

Yeah TK.

He knows his shit

Was some interesting conversation in there, look forward to seeing what "way forward" is chosen for the choked-on-SS2 car ends up with... assuming it has decent cams etc too?

Add some pretty interesting update. This is a Kando TD05 16G that was sent in for a high flow job. Using our SS1.5 compressor wheel:

This is machined kando housing with original 16G comp wheel

With our SS1.5 compressor wheel:

I don't like the anti surge slots in this housing. how ever the owner wish to keep them for the looks. lol. it should pump up the original TD05's peek efficiency by roughly 10%.

Nice - very keen to see the results on that, we are using the same turbo on a couple of SR20s. Is there likely to be comparison results from that setup?

[hypergear]

Been asked about running a ATR43G4 on that car which is a 3582 equivalent. Sure it won't be chocking on it any more, don't know what lag it will be at. Its on stock cams with head porting. Been told a turboed Volvo they worked on earlier have done the same thing, which is all tidied up with a larger turbocharger.

With that high flow, I'm not very happy with the anti surge holes thats on there, I'm sure Kando just did that to look pretty without knowing the physical impact of what it does. Run this comp wheel with SS1PU's turbine end, you will beat you current TD05 result in both response and power.

Way to find more area under the curve. I hope it ends up faster around the track than it was stock... Lets have a guess, 20psi by 5k?

Better VNT that sucker Stao...

Its different to the full SS1 PU? From memory GTScoTT runs a billet SS1 PU (I could be mistaken, I'm still getting used to names and conventions) on his SR20 and it is laggier than the Kinugawa TD05 (same as you pictured above with antisurge) - we are seeing 18psi under 3500rpm in 3rd gear, or by 3500rpm on the dyno on a stock engine. Antisurge hasn't appeared to cost any performance, but it would be interesting to see what the spool and power difference is with your high flow as the engine will not stay stock forever and I hae no doubt that your highflow is capable of more power

[GTScotT]

Lith the compressor he mentioned is his SS1.5 item which is 64mm od My SS1PU is 71mm od comp (similar in physical size to a 2871).

[hypergear]

SS1PU is the largest out of all.

Some thing similar to the TD05 is the ATR28G2 which HY_RPM is using:

Better response and more power already. SS1.5 is better then that.

[GTScotT]

I'm not sure the G2 is that much more responsive Stao.. On the day I picked up my car it felt a lot laggier than it does now. The motor has really loosened up since the tune day...

Attached is my graph which I have posted before. You will see that the G2 is at full boost between the 3750 and 4000 markers, meaning at best it would be 200rpm more responsive than my SS1PU. Remember also the conditions under which my car was tuned, and that it is only running pump 98.

[Lithium]

Cheers for clarifying, as I mentioned I am not sure on the specs - you can surely see how I'd assume an SS1 would be smaller or more responsive than an SS1.5?

Instead of speculating (there are too many claims of these HG turbos doing everything infinitely better than all of its competition without back to back proof) can you confirm the question I asked, is there going to be a comparison between the original TD05 and the new HG hybrid version? It would be very interesting to see

[Manuel Kasko]

Just did an overlay of mine and another members SS1PU's
Running similar setups except his is a return flow intercooler.

Mine is running the 20psi actuator with greddy profec bspec 2

His is running off his 15psi or 14psi actuator.

Same dyno as well and same tuner.

What do you guys think about the results?

[GTSBoy]

Yours is the red lines yeah? That's a bit ghey. Your boost drop off is costing you a lot of power at the top end. Your 2 psi of extra boost over the last 15km/h only buys you ~10rwkW. 6 psi extra in the midrange is buying you 30rwkW. If you had that extra 4 psi all the way to the top you'd maintain 30rwkW all the way to the top. And that would probably make sense.

[Manuel Kasko]

So I will have to look at preloading my wastegate.

Can you purchase better aftermarket actuators?

From what I remember it was pinging at the 250 mark so was backed off slightly. Would it have the same limitation if I was to get it to hold the 20psi throughout the rev range?

[Manuel Kasko]

Also yes mine is the red dotted line

It's not 100% but pretty much spot on.

[MoJizzy]

Not much of a difference for 5 psi eh? I'm also running SS1PU, 20psi, garret 18 psi actuator, 238rwkw.

I'll have to put my graph up, full boost around 4500 -5000, i'm really keen to bring it down a bit with the vnt housing.

Turbo comes on nice though.

[Manuel Kasko]

Post it up so I can compare all 3 results

I get full boost by easily 4000 rpm if not earlier

Might take a video and get you an exact rpm

I think there is a fair bit of difference in the mid range. Seems to be about 20kw until my boost drops off.

Remember mine is peaking at 25psi so it usually takes alil longer the higher the boost if you want to compare to yours at 20psi it gets there by 3600rpm

Only bad thing about it is it noses off abit after 6000rpm but might be sorted now due to the 4psi drop before now I got a 20psi actuator which seemed to fix it

Yeah will do as soon as i get home, offshore atm.

[Manuel Kasko]

Yeah will do as soon as i get home, offshore atm.

Offshore fishing? Or defending our country

Lol, offshore drill ship, I help run casing into the ground, work on various rigs as required.
