Hypergear Turbochargers and High flow Services Development thread

[hypergear]

Little update:

This is from the very first ATR43SS1PU (or referred as a small trimed ATR43ss2) which was fitted to a R33 with rebuilt auto:

In general Auto would lose around 20~25kws depending on how it was treated. So manual result would be around the 280rwkws mark.

Any way, SS3 with .83 dual gate rear is built. Will be tuned this weekend, hopefully getting the 350rwkws+. The GenEses charger is almost ready, will post some photos later in the week.

I just read that BMW are planning on using 3 turbos on the new M3, including 1x electric turbo.

[LANDSCRIBBLE]

^ wow gets 18 psi by 2800rpm?? Is it spooling earlier because its an auto, or?

[hypergear]

yes Auto spools faster and no boost lose during gear shift. They can sit there and do burn out all day.

[W0rp3D]

When you say the auto is rebuilt do you mean a standard rebuild or it has been modified, been thinking about going auto just unsure how much rwkw they hold standard and how much needs to be done to them to hold around 300rwkw as a manual

Think MV's rate them to 320rwkw with just a shiftkit and big trans cooler

cheers

Thanks for the info, been thinking about making mine auto for a while, if thats all it needs then i may just do it!

yeah i drove a boosted auto r32 onetime and totally loved it..just floor it and hold on to the steering wheel while you drive down the road sideways

much better and faster for street and drag racing than manual...

I have one for sale too

[GTScotT]

+1 auto skylines drive VERY well

[W0rp3D]

I wont be doing it for a few months but pm me details and i'll drop you a line when im ready to do it and see if you still have it.

Auto definitely helps with turbo lag and spool.

[Branelly]

Need ATR43G3 or G4 to work on the RB2530det. Not sure about SS3 in .83 but all other SS series are too small for that engine.

Heres my 30/25det with ATR4G3. Only revs to five grand as injectors ran out of flow and we were unable to get it to hold low boost to rev the thing out.

I will reupload once its tuned with new injectors to find out what it can really do.

[DVS JEZ]

These turbo's need some decent boost then they come alive. 17psi minimum is wheb u see th torque start to sky rocket when coming on

[Branelly]

Yeah gotta agree with that, as it is now the car starts pulling really hard at the 4500 mark right when boost hits 14-15 psi.

[SargeRX8]

I shit my pants on 19psi.

You do get used to it though, very quickly Already considering upgrading again. But the amount of money I would need to spend just to get 40-50 more hp, can't justify it at the moment. Maybe when I can afford to forge then I'll go all out.

You can get up to about 300rwkws safely on 98 fuel with stock engine. Ask Stao to upgrade it to a G3 with .82 rear housing, He's done it to a mate for $200. Very big difference in power delivery.

Which turbo do you have? I've got the ss2 and the feeling everytime gets me pumped. Do you run e85? Forging the motor won't give more power, only forge if it pops otherwise I'll be buying an rb30 block

Yes, I'm currently making about 260rwkw. Thing is with sending off my turbo for Stao to modify, I live in Perth... So that's a huge down time for my daily

I've got the G2, .64 housing. It's still just as quick, it still scares the pants off any mates that get in my car. It's just that I'm used to it now, 350rwhp got old quicker than I expected

No E85 in Perth, not at the pump anyway. I know forging won't give more power haha, I meant that when I can afford it I might forge and go for 500+.
