Hypergear Turbochargers and High flow Services Development thread

Whilst I don't disagree with your statement, what I meant by "better" is feeling smoother and more effortless. The car may actually be faster at the same boost, but I couldn't really tell this from the feel...I'd have to do some timing tests.

The psychological feeling that your foot is only at half throttle, producing the boost that normally appears at full throttle, is certainly nice.

[siksII]

. I take it you're running an SS1PU, siks?

Yep, normal SS1PU

7psi on stock turbo doesn't = 7psi on this turbo which is why it feels so much better. it is pumping a lot more air.

This is true with the SS1PU compared to stock - I noticed on the freeway in 5th gear more than anything - light throttle and 10psi gives you better acceleration than flooring it on 10psi with the stock turbo.

Holy hell im excited to install this bad boy!

Any fitmeant issues?

Also where did you get your gaskets from?

I didn't fit it, OTR did the installation for $450, which included replacing all exhaust manifold studs. There were some broken studs, so I'm glad I didn't screw around with the install myself. As far as I can see, the only fitment issue they would have had, is that my whole exhaust now sits about 1 inch further back, because Stao's dump flange sits closer to the firewall than the standard dump flange. They didn't modify the exhaust though, and my tail pipes come further out the rear, so the whole system must have had enough slack in it. According to Stao, all you have to do with the standard exhaust system is remove the gearbox mounted exhaust bracket. I'd previously removed this part and my exhaust is custom made, so not applicable.

Exhaust manifold gasket was genuine Nissan, the rest were "permaseal" that I got on eBay (don't get the cheap eBay ones, they are shit).

Cheers for the info birds

I'm going to have a shot at installing it myself if I fail then I'll go to an exhaust shop or similar.

let that guy in the chopper install it for ya Kasko ! ! He looks up to the task....

[Manuel Kasko]

Haha everyone keeps telling me to change it

Stick it to the man \../(* *)\../

God I can't wait for my tune, this turbo is begging to be unleashed! So much self control required

[ARTZ]

It always scared me, the thought of upgrading my turbo and losing too much of the factory response / daily drivability. If you have these concerns, get this turbo. What little response I have lost, translates to a better daily drive all round

haha,

Oh how concerns of lost response quickly fade when the boost hits ya.

Agreed. Honestly, most people I have met (in person) who are concerned with stock response blah blah have never been in a laggier but fast car.. once they experience that they forget about off boost and at low rpm issues.

Same with with NA is best crowd - ive lost count of how many of those people i have taken for a ride after which they shut up about NA and suddenly want to buy a new turbo car lol

[hypergear]

glade to know every thing's going well.

This might be off skyline topics but any one know any good ecus or perferred plugin ecus or flash software that I can run with a VW Golf GTI 2L turbo DSG motor? Got a offer to develop bigger bolton turbo for that car but its totally new to me. cheers.

Also I will be starting some evaluation on externally gated turbo combinations, and will be able to supply those at a very reasonable price including some of the popular TD06 and T67 combinations. Possibly with billet wheel and ceramic roller centers.

Stao you have PM

It would be interesting once you get your car tuned to drive back to back against Ric's GT3071r 280rwkw car.

Should be a very good comparison

There are extremes of it though. When I drove Stao's R33 I didn't like the lag at all, it totally nullified the awesomeness of 300rwkw+ in the top end. Each to their own though - I like a car that can move through the traffic gaps quickly or rolling drag without dropping down a gear. The SS1PU, so far seems like a very good balance between a boost machine and a commuter.

Will be doing this for sure! I'll also be heading down the E-flex path after I'm done with the PULP tune, has anyone done this with the SS1PU yet? Will be interesting to see what she is capable of.

[Rolls]

I remember your old head from ages ago had valve float, what did the dyno graph look like when this happened, did it just go flat and not make more power?

[SargeRX8]

Brake boost to compensate for lag

[t_revz]

well im joining the HG club. SS2 ordered. will also be running poncams and quite a bit of head work plus all the usual stuff. cant wait

[copycutter]

My result

[Manuel Kasko]

Pulled out everything today and will be fitting the PU tomorrow. Can you believe my dump pipe bolts were able to be unscrewed by hand and also the manifold bolts

Either the freezing stuff I purchased from autobahn is amazingly good and everyone should get it or the last person who did them up had no clue!

[rondofj]

My result

I hope thats not yet another ss1PU failed to achieve its 'rated power'???

[copycutter]

That is an ATR43 G3.
