o.O You want to test it on a car? Like put a vinyl picture of your car on another car? Or put a picture of your car on your car? BNR34 Inception! I no understanding. Looks good by the way.

Agreed. I thought your choice of size and offset much better suited to an R34.

I'm a bit hesitant about jumping into this discussion... Remember the question is about an 8" rim. To get appreciable stretch on that you would need a 205 or 215 width tyre maybe which is smaller than a stock tyre. Each to their own and all, but it just seems a bit silly to me.

Lol

Tried an offset calculator? I would suggest: no. Not without guard and camber mods. With above mods you can fit pretty much any wheel your little heart desires.

I like that photo very much.

Thank you sir.

Not much love for the Series 1 R33s but I like mine.

Slight update. Work XD9s F: 18x9+20 235/40 about 2 deg camber. R: 18x10+38 265/35 0 camber. Will go one size wider in tyres next time.

Galvsport does quality work, but they don't tune Nistune. They get Nistune tuning done by Allsport (or in my case PZP because Allsport was booked up). Also, +1 for Hyperdrive. Been there a couple of times over the last few months. Good turn around times, and from what I gather he's open to working with non-mainstream stuff like Hypergear turbos which I've noticed many other workshops will tend to steer clear of. Things I've particularly liked about Hypergear: Good turn around times Personable staff (even the younger mechs will say hello and help rather than leave you standing around) I've gotten good feedback after the tunes (e.g. not just "exhaust is restrictive" but "noticed your dump pipe starting to glow early in the power run which indicates...etc").

Yep, actuator was changed to 18psi. Didn't change much at the time though.

I dont expect so. They did the dump pipe, actuator and tune pretty quick last time. One day I think from memory.

I considered Deatschworks at one point and then found a bunch of reports of poor reliability on the net. That was enough to turn me off.

Thanks Mick. Don't worry, I'm already enjoying it. this is more about optimisation.

Ok, bit of an FYI. I've recently got my hands on a 0.63 A/R IWG housing. Car is booked in for install and tune on 11th December. Note this will be on the same dyno as before, just bolt in-out and retune, so should provide an interesting comparison if nothing else. Will post dyno sheet in a few weeks.

Photos?

Well I've literally just in the last 5 mins ordered a 0.63 A/R housing from ATP in the States. Hopefully can get similar benefits as per above. Will post results in the other thread when it's in.

Not sure if referring to my GTX3067 result, or typo, but nonetheless also found the results of 0.81 v 0.96 very interesting. Below quote from the original page in particular: The .96 A/R only added lag and if you reference the boost spool comparison below, we also weren't able to see as much boost with the duty cycle all-in. This tells us that we were at a limitation of the compressor wheel flow itself and not because of back pressure. Not always beneficial to go larger A/R it seems. Anyways, sorry to digress from subject of thread. Thanks Lithium for posting above info.

Damn. Sounds like the GTX29 may have been a good fit for me. Will be interested to see results when they come out.

Looks very nice indeed Mark.

Engine bay looks great. Galvsport do quality fab work.

Bit of a long shot perhaps, but... If you have a Garrett internally gated housing (GT30 T3 - 5-bolt outlet) in 0.63 A/R, let me know. Garrett part number: 771300-0006 Note, I'm specifically after the 0.63 A/R version (already have a 0.82). Cheers, Mark.

Lithium, is there a link missing from your first example?

Thanks for your thoughts Disco. Hopefully I can get my hands on a 0.63 housing. It's what I'd wanted in the first place.

I'm not sure any more. The compressor map is pretty close to the GT-RS, and most people get around 240-250rwkW, a bit more with head work or cams. I'm not clear on what benefit you actually get from having a bigger turbine... On the turbo speed topic, I don't know enough about how it works really. Are you suggesting that at say full power, it can't get enough energy out of the exhaust gases with the 0.82 housing to spin fast enough to generate the required boost? If this were the case it would mean that the wastegate would actually be closing as revs increase right?
