This is recent and yet interesting result sent in from a customer running a SS2 turbocharger with a R34 GTT Auto. It was used as a bolton replacement internally gated.

It has:

Blitz front mount return flow cooler

1000 cc injectors

255 pump JJr front pipe

Z32 AFM

Nistune

E85

Stock Auto with a transmission oil cooler

300rwkws @ 17psi of boost:

I was reading through the thread and was going to weigh in anyway, though looks like you're very much on the page I am reading from - so I'll +1 with with a bit more anecdotal evidence to support it

The ATR28SS15 would be a perfect turbo for your application. I didn't look into some thing even smaller as it doesn't make that much of a difference in response but did loses quite a lot of power. I'

^ lol... maybe I'll use a 3" intake pipe and add in more bends.. that usually gets the suuuuuuuuuuuuuuuutuuututuutut going LOL. Anyhow, some real world facts to back up the results.. errbody likes ti

So car is booked in for a tune on thurs. previous tune was 345rwhp on 17psi with the now outdated ATR43G3 type A internal gate. Now has the later version with the updated comp housing i think, ball bearing cartridge and type B housing (thanks to Stao for uprading me for free!). Tuner has recommended to block off the BOV after i asked if the stock one could hold 20psi. Cant wait, havent boosted for about 3-4 months :(

Its extremely important remembering to preload the actuator as the tuner's tuning. keep on preloading if are seeing boost tapering off before the desired level. It might be 5mms or could be 15mms, the more you load it the higher up top boost level it will hold, more boost makes more power.

4-5mm preloaded on it at the moment. I've never had the boost tapering off issue, infact its been the opposite with mine, pressure increasing towards redline.

Good luck Landscribble, hope the kw's flow freely :)

I've got an g3 type A, so it's definitely possible to get a result.

Thanks, i hope aswell but now im not really fussed if it doesnt match Stao's results, aslong as i can drive the thing im happy. I know the turbo's can make the power having made 279rwkw previously by a different tuner, i chose to go the type B for a little faster response.

I preloaded mine Around 8 or so mms, With a 14 pound spring, it boosts to 23 psi, tapering down to ~20psi now.

I find it very wierd its even getting to 23 psi, ( boost controller is Off )

Does this mean to much preload?

I think its a good boost level. Usually the boost curve starts to spike then drop. with more preload it starts to hold, and if over loaded the boost starts to creep. Thats I usually adjust mine with internal gate.

Ill prob remove the controller all together then, as it might still be affecting it even plugged plumbed in.

It does feel alot more consistent when boosting now.

If youve got it able to hold 20 off the spring (peaking 23) that is really good.

Provided your car is tuned at that level I give you the big thumbs up.

Just watch it when the weather changes as that can make it jump :)

Car is tuned for 22 pound tapering down to 14-16 pound.

So....not really tuned now..
I will be getting a new low manifold/external gate soon so im hoping to hold of on a new tune until i get those.

Question: How do Dyno Tuners measure Boost ( pressure )?

Might be a dumb question, but just want to know how they measure.

      GOT SUM's RB34

      This morning I carefully reinstalled the manifold and started looking at a couple of things I need to do.  Heat wrap arrived sometime today so I popped into the shed with the missus dishwashing gloves and started wrapping the first half of the dump and the screamer/plumb back.  Once I do the second half I'll be able to final fit the turbo and exhaust up.  Also pulled the harness out today and started terminating it at the ECU end. A connector is done, just need to run the remaining wires that arent in the harness - 12v, gnd and couple I/O

      Thanks for all the replies! I also wanted to ask if wheels that were fitted on Ford Falcons would fit the 350GTs as well? In the area I'm at there aren't that many options for secondhand wheels and new ones here are way out of my budget. From what I've seen, most of the wheels that are available that were fitted on Ford Falcons have an offset of +33 to +36, with a centre bore of 70.5mm whereas the stock 350GT's ones are 66mm, can't seem to find any hubcentric rings that fit that difference though.

      215/45/18 tyres are probably a little on the low side compared to the factory tyre, it should be closer to a 245/45/19, which will get you about an extra 11mm of height, and should make you speedo read a bit closer to reality. 245/45/19s will be a bit too far the other way and you risk a speeding ticket as your speedo might read slower than your actual speed.  245/40/19s would be correct if you are going to 19in rims, they will give you a similar total diameter to the 245/45/18 tyres.

      That's something I forgot to put in my list. The aggressive anti-squat in R32 is a f**king menace. I still need to decide if I'm going to drag the subframe out of my car and weld in the GKTech corrector kit. The main reason to dither is the need to switch to spherical joints in the lower arm to account for the twist induced in the rear pivot caused by lowering the front pivot. And yes...we do put better subframes in R32s, and I wish I'd gotten an S14 one instead of an A31 when I did the "take off and nuke it from orbit" HICAS delete all those years ago.
