Important fact to remember, in a drag racing senario the actual power transmitted to the pavement is alot different to the dyno graph. Unless you are willing to rev/antilag and dump the clutch on the dyno, then while the turbo is still spinning and has built up inertia change gear. Will show a completly different curve as turbo motors are not static output as a N/A motor would be. The graph would be alot fatter with more midrange/earlier boost "response".

Having said that, who the fcuk races a car from ~2,000rpm up to redline in 4th? Or has a direct drive dragster/rail that has no gearbox? That's the only result you can estimate based on these chassis dyno graphs...

There are a number of guys over here who can vouch for simon's TO4z setup as being a very attractive alternative to 2530's. The 'response' as people are starting to point out is to do with a stopwatch and how fast the engine spins up and boost/power happens, from this perspective the TO4z does infact seem to do this as well or perhaps even a tad better than the traditional 2530's with the added bonuses of more power, less moving parts, less parts in general and more room in the engine bay.Lets face it we are all looking for that pot of gold where we get fewer trade offs.

A good friend of mine has been lucky enough to witness the road going comparison to 2530's and although there where some engine differences it's very obvious the turbo delivers the excellent response we expect from 2530's from purely a timed delivery perspective (from on the gas to go).

At the end of the day I think the proof is in the pudding as they say, so Simon you just have to take a few more of us 2530 twin owners for a ride so we can back you up :D

what mods have you done becaues i am chasing 400 all wheel kw, currently doing 241awkw i have

power fc+controller

avcr, currently trying to tune it

high flow turbo. running 1bar

3.5inch catback exhoust+ 3inc high flow cat currently getting 3inch dump/front pipe the exhoust and cat has been added after the dyno

after market avr intercoller, looking at a better intercoller

Generally speaking, people want different things from their cars. So keep their GTR's stock, some pursue lap times, others drag strip times.

At the end of the day, anyone who owns a GTR that wants to run 10s on pump fuel without nitrous, is going to have to have to sacrifise response for top end power. You really cant have the best of both worlds. To some a 2500RPM power band is all thats needed, to the track driver it needs to be double that. 415 kw at the wheels is huge, and is enough power to post a 10sec pass, thats a great achievment. To some it wont mean much, they may look at a GTR with N1's that can do 1.40s round eastern creek as impressive. Critisising the response of a particular setup/turbo combination is fairly petty IMO.

jesus pnblight cant u say once that u think single turbos are ok, u are constantly on ya bloody twin turbo bandwagon, gives ya the shits, and simons has done an awesome job and proved it where it counts, and congrats simon u deserve plenty of respect mate :)

just an observation peter in the years ive been on the forums u never give credit to the single setups ever!

cheers

Brad

hehe, its not that bad m&m

Sometimes everyone just gets a tiny bit too passionate.

Its very rare.

Guys - just knock it back a notch. We all have our own beliefs.

Dont try push it upon one-another unless your using given fact as opposed to what you think works best, which at the end of the day is all that matters :)

Top effort Simon, will have to look out for you car next time I am down at the 'plex.

Just got myself back into another R32 GTR and I am very tempted to build it up but might wait until I finish the zed before I get carreid away.

Wonder how the TO4Z compares to the GT35R...

Geez Cuong - the only build that I know of that's taken longer than my R is your Z!! :lol:

I have a bit of a comparison between my car and Morgs' car on the same dyno, with 0.1 bar of boost difference. Very much a different response. I will post it up with Morgs' permission ... but not for a couple of days

Congrats on the result. The T04z people seem to be pulling big numbers

Thanks for the reply brad but i think u might go past me horspower power wise as u got a nice forged crank to rev ut hard and 2.7L ! I would like to try miine on 2 bar in a few weeks with some bigger squirters and see what the t04z is capable of because at 24psi its showing no signs of letting up yet.

I think this is true to a point but with turbo techonology of today and eveyrthing else advancing so far i think you can have the best of both worlds now . I ran a 10.9 babying the stock gearbox , the car makes 454rwkw's and has a power band 4000-9000rpm .

    • Hey everyone. Is there a way I can get the original window sticker (maroney label) for my 1995 R33 GTST? I doubt I’ll be able to ever get it but it’s worth a shot to ask
    • Have a vb in honour of the car comming back
    • It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪
    • And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil
    • Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.
