i was comparing simons 625hp not my own setup nick.

cerbera thats something i expected from you on a forum, just your style lol

borg warners are where its at :P

come on its a matter of personal preference i think, everyone has there own ideas of lag/power/fast.

No doubt they are animals, but when response counts (if the courses are indeed as tight as above) then you really want -7/GT30 style setups for max response, you'll be faster that way

t04z too laggy for any track work unless its a big open circuit event and u like keeping it above 4500rpm all day, even the gt3540 ive seen isnt that much nicer response wise. If u plan any sort of mo

pretty much the same engine/turbo but one has 6-boost twin scroll and one has china manifold and a dodgy gate

shows what a well set up manifold/gate/boost controller combo can do...

Would it be possible to overlay a stock curve for those following at home?

Ah ic ic - makes more sense now :P

Would be interesting to see the GT35 on a good setup i think, one thing that's missing from the comparo's haha ;)

Here is a graph of my GT35 with .82 rear on a decent manifold setup

also i plotted it on brockas graph to compare, its the black line.

Didnt realise that its a RB26, for some reason i thought brockas was a RB30det, That would explain why it seems so laggy to me. Oh well interesting comparison between rb30 and rb26.

Its a r32 gtr diff, 4.11 ratio, what are the ratios in the other graphs?

Car should be running in a week or so. And i'll head to the plex again see if it can go decently into the tens on street tyres. To4z has the top end to get decently into the mid 130mph's. With the small things its had done to it this time round 650rwhp should be enough for mid tens on street tyres.

I'd love to see a GT4088R compared with these things :D

lol give my bank balance time to recover after this change in setup first!!

I've now taken 2 people for a spin in my car. They both saw the graphs before going for a drive, and said the exact same thing. "It doesn't feel as laggy as it looks on the dyno plot".

Would love to have it snapping on boost hard, but I don't think my gearbox would like that...

Just looking at Pauls Graph compared to mine as a t04z to to4z comparison seems to be quite a bit of difference in response. They are both roughly based on speed vs hp and at say at 130kms pauls is making 220hp ish and mine is making almost 400hp at the same speed. Just an interesting comparison as mine didn't really feel laggy at all and should be better with the new setup of bigger valves and bits and pieces. As a comparison mine was running 27psi and i think pauls is 25psi so pretty close.

I think you can put it down to the boost control.

You can see in your graph the boost comes on hard where as Brockas is a bit lazier. A good boost controller makes all the difference.

Indeed arguable. Effiecent range on the GT35 is probably 28 - 30psi and 35 + on t04z.

Brockas like most probably not keen to push to those levels.

All your graph comparo proves is that brockas china manifold / setup is crap compared to 6boost and your setup.

GT35 on your setup would have rocked.

LOL coming from the guy that never raced his 26 !!! Simon N has times you got wannabe ......

Final word

IN PERTH GT35 smashs the t04z on RB26. Best single t04z time is like 10.8 on a fully built motor ??

There is more then one GT35 RB26's quicker then that IN PERTH.

RockoGTR's 10.4 on Nexan Radials is a GT35 and China manifold. We are going to put it on E85 and MT Drag radials and try again.

I now have one of the best boost controllers on the market, the Blitz Dual SBC Spec R.

Unfortunately, it's my wastegate which is letting me down.

Simon, we overlayed yours versus mine and yours destroys my setup everywhere. It's on earlier due to the head porting, but yours snaps on boost so much harder. I think once I sort this wastegate issue it will change the midrange dramatically and also carry a few more HP to the top.

For now though, I'm going to see how long this $300 2nd hand box lasts... the fact that it lasted the dyno run means it's been good value so far...

      I am currently going this route. I am curious how much horse power you put behind the cut bell housing? Collins was telling me I am going to crack it and bluh bluh bluh. Because I didn’t buy the custom fly wheel from him. I am looking for somewhere around like 500 hp

      Thanks @PranK for the updated member status, much appreciated! 👍🏼 Now, about those pics… Unfortunately I could only find ones that I took in the dark. I was soon to discover that underneath it wasn’t in the best shape, but it was mine and that’s all I cared about at the time 😆

      A little PU bush story

      By GTSBoy · Posted

      Oh, and only having done this task yesterday, I've now driven the car ~60km since, and while it is hard to avoid placebo effect and confirmation bias, I reckon that some annoyances I had with the way the car has been behaving have improved. Which....kinda makes sense, I guess. If the bushes were really stiff and resisting rotation, they would have been contributing to the effective wheel rate. And if it was more so on one side (which it was, because one side was worse than the other) then.... you might imagine that the additional rate would be asymmetric, and potentially even different between compression and rebound. And so... the car has been twitchy at higher speeds - like freeway on ramps. It really shouldn't be. The wheel alignment is good and there are no (other) known problems elsewhere in the suspension. But at 90-100 on a long sweeping ramp, tiny steering wheel motions would make it feel like it wanted to rear steer. Quite nervous. At lower speeds it would heave about in a manner that it didn't use to. Didn't want to put power down, etc etc. Now...seems to behave better. Am going to have to concentrate on the various corners where it has exhibited weirdness, on the rare occasions when I can get a decent run at them without Methanial getting in the way in his D-Max/Ranger/LDV Van/etc.
