U are spot on. Thats why i try to convince most customers to do everything at once then to keep adding parts that require a retune. Costs more up front but saves alot down the track

Hence why it has taken me 2 years to finish my damn car, because i KEPT adding to it.... :P BUT overall it will be worth it once its all tuned....

So if u were to run 15psi Jez how much would u expect it to creep ?

As BSA said. This was the minimum boost we

Could run which means no boost controller at all. We even held the wastegate flap open and it still climbed past 22psi

Except when the minimum boost it will run is 18psi. Ask Mitcho. I dont feel its safe to try max the injectors out and leave them running like that.

there are plenty of successful highflows running 15psi or less mate, cmon........

Yeh, it's a bit of a lucky dip with the actuator you get with the HG turbos. I asked for a 14psi several times but on the dyno it wouldn't run any less than 18psi like Jez mentioned. I dont know if there's anyway to tell what actuator it is without it being on the dyno either, so you won't know til you get it tuned...

Or 20 psi like I found haha

More boost the bigger the smile :D

The more tears long term as well maybe haha!

20 psi is probably fine though and it's not like you are hitting 20psi all day everyday either. It'd be for a couple of seconds max on the street. If you are at a track on full load for several laps or whatever then it might not be ideal for a stock engines longevity...

On a side note, birds made 250+rwkw on only 16psi with his ss1pu I think. So good numbers are possible without needing to run lots of boost.

Yeah we put birds results down to difference in dyno.

Or he has a healthy engine.

Jez warned me about tracking the car on 20psi but I dont have plans to track it just yet.

When I do I will source a better quality actuator with say 14psi then bring it up using my ebc

Anyways lol talking about hyper gear in kando thread.

Back on topic

What ever happened with the bloke and his cracked comp wheel?

lol thought I was in the HG thread for a second.

Yer 258rwkw and 16psi from the SS1PU highflow, though interestingly, it was sitting at 15psi where it made peak power. There's definitely more in it too - my setup has also been said to have a lot of restrictions, though I do have quite a healthy engine. RacePace's dyno has never been said to read happy, however, Jez's could read low too.

In the end, screw figures, all that matters is whether it puts a smile on your face when you mash the pedal, and mine does :)

Hey guys. I'm getting a td06sl2-25g. Just wondering is it work the risk of getting the anti surge housing. Or should I just stick to what works and get one without anti surge. Btw 10cm rear with a/r 0.60 comp housing

The general consensus here is to get the T67 instead. The specs of the wheels are the same, but the T67 uses a TD07 shaft which is thicker and stronger.

The T67 also has a .70 AR comp housing, which will effectively need less boost for the same levels of flow, and is an oil only turbo which makes it a bit neater to set up in the bay.

Go the T67 10cm!

Nah I didn't mean 20g I meant 25g. I think it will be too laggy and a headache to fit low mount on standard manifold (0.70 a/r) which is what I want to do hence why I would like the 0.60. The only difference is the housing a/r and the shaft diameter which is only 8% smaller. I would like to see full boost before 4000 on around 18psi. I haven't seen a t67 reach full boost before 4000rpm on 98. I would be happy to be corrected as I could go a t67 with billet wheel.

Mate the difference between a TD06SL2 and a T67 (in terms of performance) is only the difference in the comp cover.

That seriously wont effect spool like what you are imagining, its more so going to effect how much flow the compressor can give at what pressure ratio. And as stated the larger housing is going to need less pressure to flow the same amount. The spool difference is likely to be negligable.

Trying to fit it on the standard lowmount though, now your talking a different can of beans... And I suggest you consider a hypergear instead. Be it myself, I would rather a standard issue hypergear G3 than I would a T67 on a low mount. If you were to put a highmount into it I would then say Go the T67.

I disagree that spoil difference is negligible. Unless negligible is 300rpm. A larger housing will take longer to compress air as its the same wheel filling a larger area. Regardless the question was with regards to the anti surge housing

    • Well, I'm tired. I'm tired because about 4PM yesterday, before today's appointment someone immediately bought my bumper. They couldn't get it any other day as they're on the way back to NSW. So I had to do that big GTR conversion I had been planning. Unfortunately, the information on SAU about what you need and how this is done is incomplete. So what should be a simple bolt on affair, yeah, it's not. Did you know if you use all GTR items the bonnet won't close? This little manuever sent me into about 1am the night before trying to dodge a way to get it closed. I will have to revisit this in the next few days  - or maybe not, I may let a body shop figure it out. It all needs to come up and my motivation to pull the bumper off is low. It also seems to hit things in the bay where the GTT bonnet didn't. Yes I used 100% new OEM GTR items. Today, I had the joy of driving to the dyno looking like this: Given I had roughed in the fuel and given sensible but pretty conservative timing, I didn't really bet on having the car drive out any real difference than when it drove in. Sadly due to a miscommunication and laptop fun and games (and almost bricking the dongle, prayers and firmware updates indeed), I ended up using HP Tuner credits to licence the car that was already licenced. So in the end my laptop was used. It turns out my butt dyno is still well calibrated after all this time. The 325kw was on 74% Ethanol, the 313kw line was on 98. The other line is the 'before' line which was 281kw. While the numbers are pretty low, they're pretty in line with what you'd expect. Even if US dynos bump the whole result up about 50KW, gaining 10-15% is similar gains.  The curve of the cam is pretty much spot on with what was discussed as well. All this said, it still feels bad to not see the number you secretly want to see. Even if the car drove great beforehand, and I knew pretty confidently the car would drive out much the same way it drove in due to the nature of a wellish dialled in LS1 not gaining much if anything at all from being tuned from where it was. As expected, the car isn't particularly sensitive to running it at anywhere between 12.0 and 13.0 - And the initial timing at 20deg and 12.0 made 308KW. So 3 degrees of timing, and leaning it out to 12.7 for 5kw, anything above stopped giving any benefit until E85 (which has an additional 2 deg as before). Car itself behaved entirely fine. I found out that 100C = 1.15V! IAT at about 7pm was 19C. I might mess with the bonnet mounting.. but given the REO NEEDS TO BE CHOPPED TO FIT A GTR BAR this is possibly something I may leave gathering (more) dust until it returns to paint jail.
    • It sounds farrrrrrr too cold at your place Duncan... Here I was thinking our 10 degrees overnight is getting cold...
    • oh yeah, reminded this morning....bin lids frozen shut too
    • In my case not, because of total reno. But yeah.
    • Did you use an electronic speedo drive? Does you speedometer read all the way to 180km?
