What would you say the SS1PU is equivalent to?

Awesomeness

[Birds]

Awesomeness

Whilst I would agree that an intangible thought process or emotion expressed as a singular praise word might be a fairer comparison for the "rolling thunder, force of nature deus" that is the SS1PU...I would like to see a mortal at least attempt to compare it to something more tangible and preferably metallic.

[ARTZ]

You put way too much thought into that last post Birds..

What would you say the SS1PU is equivalent to?

custom spec 71mm compressor, which should spool as good as a 52 trim but make more power than a 56.

turbine is similar to a GT28 but slightly enlarged. Combats choke and surge experienced on an actual 2871/GTRS.

in essence our cries were heard that we wanted a GTRS competitor. Stao went one better

an SS2 is the same compressor on an enlarged GT30 style rear wheel. So a hyper 3071.

I hope I was allowed to share this data

Had to read this a few times...prob due to just waking up.

So bigger turbine but same spec compressor as 3071. Correct?

Although prob lighter comp wheel I guess

[GTScotT]

turbine is slightly larger trim than a GT30, compressor is same as SS1PU. Which is a lightweight billet 71mm wheel.

[hypergear]

Its more of the wheel sizes are similar, the actual trim and blade profiles are very different.

Here is a ATR43G4 (big turbo) that's been recently installed on a R33 stock Auto and shift kit with 98. I think thats the most I've seen out of a auto so far and its only on 16.5 psi of boost.

Might have found most of my mid range low power issue this morning.

Exhaust cam was 3.5 crank degrees retarded. Adjusted to 0 (115 btdc)

Inlet was 6 crank degrees retarded. Have maxed the adjustment getting it to 2.5 degrees. Waiting for my son to have a nap so I can jump the belt a tooth and adjust it to 0 (120 atdc)

Also waiting for a quote on a new cat-back system to be made at a mates business. Need to get the bell mouth off and open that up before it goes on.

Hopefully will catch up to everyone down low

Good work Trev! I knew cams would be out!

Can u please share the secret to dialing these? Ive just finished assembling my SR and need to do some dialeroo

Is the G4 like a 3540 stao?

Hey Martin I've bought a degree wheel to go on the crank and made a piston stopper using an old spark plug and threading a bolt through it so you'd welcome to borrow.

Set to TDC visually. Install degree wheel with TDC about where pointer will be. Wind clockwise 30-40 degrees. Fit piston stopper. Wind backwards and record number. Wind forward til it touches and record number. Average of these is true TDC. Adjust pointer to zero at that position. Remove piston stopper

Set dial indicator on lifter bucket of no1. Rotate to ensure it doesn't get caught as there is stuff all room. Wind til at max lift and zero dial gauge. Rotate around til .050" before max lift and record number. Rotate past max lift back to .050" and record number. Quick calculation to find the average will give you max lift degrees. Compare to manufacturers spec to see if its correct. Adjust as necessary.

Very quick explanation as I'm busy ATM.

You need a degree wheel, dial indicator, piston stopper and tooling to remove balancer at least.

Finally got my car tuned today with the SS3-eg.... pretty disappointed in the result... only made 287.5 kw.

Something must be going on because I think it should be making a bit more, I was def hoping for something over 300.

I was trying to run it on 20psi, but it was only getting to 18-19 and then dropping off to 17ish.. Ive only got the 7psi spring in the gate and the boost controller is maxed out.

Im going to try and put the bigger spring in and hopefully get it steady at 20psi and see what happens.

It was heaps weird, when we had it on the dyno the first run made 285, then we ended up throwing 7deg more timing into it and leaning it out more and it made absolutely no difference.

Setup is:

- SS3-eg

- 6boost manifold

- 50mm turbosmart gate running screamer

- 3" exhaust with only 1 rear cannon

- Greddy inlet manifold

- E85

What do yas think?

[pipster11]

what intercooler?

[arrydjay]

just a standard 600x300 chinese job

[pipster11]

could be the issue

still have a cat? drop the exhaust off at the dump?

[arrydjay]

got a venom hi flow metalic cat, the cooler seemed to be doing its job, on the dyno it was hot on one side and cold on the other, but I suppose it could be a restriction.

I didnt want to spend heaps on a cooler as they just get fked up so quickly, and I end up just changing them out

[t_revz]

Ss3 and e85... Something very wrong there

What did the tuner suspect? Graph?

[GTScotT]

that doesnt sound right.. you describe it at really simple which should work in theory.

Whats done to the motor itself? Whats changed (other than turbo side) since the last time it made decent power? I dont think the turbo side could be slowing it down, other than exhaust but that sounds pretty sweet.. If its all 3" straight anyway.

So that leaves a crappy intercooler, intake restrictions or possible mechanical issues with the motor.

Need to consider changes the most, like I said..
