Were they run on the same dyno??

Yes, exact same dyno. Dyno Dynamics in Shootout mode.

and the 468rwkw one has run 132mph.

Can you post sheets please? Will help a lot of people decide if the HKS turbo is worth the 2k more...

dirt can you post up bp98 tune as well because i want to see comparison of hks t04z with garrett t04z on same fuel

mine made 428rwkw on 24psi (garrett) and another has made 468rwkw on 25psi (garrett). both were standard stroke 2.6l's

is this a 2.6l?

Yes still 2.6 & it made 422rwkw on 22psi & was on synergy8000.

my hks t04z has gone 585rwhp (440rwkw from my calculation) on 18psi on 98 pump fuel on a very very low reading dyno, another brand new dyno dynamics one i went on recently read 40hp more (520hp to 560hp) on lower boost tune, so i reckon it would of been a bit over 600rwhp on any other dyno.

brad!!!

clearly you should know you had about 150rwhp of timing in that tune to make that power

actually it was a different dyno i think, cause my car was tuned on the new 4wd dyno (in 2wd) and chookos was on the old 2wd one

chookos made 454rwkw or 608rwhp with similar tune to mine, but made more with cam timing and further tuning. my cams never got moved from zero so may have been a little more in it!

same tuner, same workshop, same fuel and very similar engines etc etc

ok, could my standard valve springs and 260 poncams be limiting my power on 24 psi with a t04z to 376awkw (.84 split a/r ex housing)..???

Just a little bit, Dave. :bunny:

PS, I'm still waiting!

interesting for me, that youve only run 132mph with 460rwkw. Ive seen an r32 gtr with 360rwkw go 134mph @ 10.8

lol Simon, he has never done a power tune on my car only a run in tune on the first motor years ago ;) everyone knows he wont touch an autronic ecu hence why i never used him in the end.

Simon's time (10.91 @ 132 with 460rwkw) was with a stock gearbox and $90 shitty tyres.

At 3256lbs (std 32 GTR weight) and 485hp (360rwkw) you shouldn't be running 134mph, more like 124mph.

Can I ask what turbo was used?

Let me guess, it's a 700+hp rated turbo, running in its peak efficiency, and "only" making 485hp at the treads. I'd suspect a very low reading dyno....

Besides the point, all I want to see is a compo between a HKS T04Z and Garrett version, someone post dyno's!!

something im struggling to believe unless it was a super low weighted car with a dog-box on slicks and with that ET i doubt it.

134MPH = at the very least 400AWKW in a R32 GTR

im pretty sure he ran around 134mph on another pass...

he was also running standard box so change from 2nd to 3rd was slower than leasurely which would have dropped the mph a fair bit i would imagine.

GRRRRRRRRRRRAAAAAAAAAAAPPPPPPPPPHHHHHHHHHHHHHHHHHHHSSSSSSSSSSSS

r32 gtr, os giken gear set, hks t51r. Not sure if it was lightended, il have to ask him next time i see him.

another r32 gtr with n1's went hi 11s @ 125mph, he had just over 300rwkw. Wasnt a fancy set up either.

My boat did 139.67mph with 456 rwkw although only 10.70 with 1.57 best 60 foot. It had 540 pound springs at the time in rear, yes way too hard and wouldn't weight transfer, and front diff not there.

PS Good power Dave and good result. PPG helical dog box would have less power drain I guess over stock synchro box??

HKS T51R... SPL or KAI? Either way its a ~900hp rated turbo, and you reckon it only makes 450rwhp.

Either it's being transfered through a rubber driveline or it's running 14psi.

As I said, thats one hell of a low reading dyno. It's physically not possible for a car that weighs as much as a GT-R to do ~135mph with 450rwhp.

No they would be about the same...the gears are the same basic design albeit a more agressive tooth profile and far superior parent material on the PPG. The way each gear is selected whether it be dog engagement or synchromesh has little bearing on the losses after the gear is selected.

    • I certainly fall into the annoyed camp, but glad to hear that if it's happening at low boost then I'm not likely going to blow a turbo and end up with metal shards in my oil. Just feels like it prevents me from really driving it without hesitation and "peak" performance. Wonder if it's the VCAM, it did an impressive job of shifting the torque curve and faster spool, but maybe now it's "too fast" and there's too much air for how open the throttle is.  Based on some other threads, will also do some reading on synchronizing the actuators. They are the default actuators that come on the Garrett's and I would think they would be set the same coming from the factory, but if the turbos don't actually work exactly the same way at the same time as previously mentioned, it would be worth making sure the actuators are actuating together properly
    • I went down this rabbit hole before, ended up sourcing a motor from the UK (I'm in Japan) which also didn't function correctly. With the original motor, I disassembled it and reassembled it and it works somewhat, sometimes. What I could deduce from all my screwing around is that there is calibration of the gears on the inside of the motor and two ramps on the main gear which activate switches that operate the motor and move the sunroof either to retract into the roof or tilt. Where I got stuck was that, it seemed in my case that one or both of the switches that are activated by the ramp on the gear did not always activate and thus the motor did not move, causing it to sometimes not retract or tilt (apologies, I've forgotten which way it didn't work.).  Of course this part is discontinued at Nissan now, it's the same part in the S15 but no other models. I also contacted the manufacturer of the component for schematics - forgot the name, they're based in Gifu - but they declined to share the information due to being bound by an NDA, sadly. Looking through my pictures now, it seems I last had a crack at this in 2022. See, I so kindly wrote "open" and "close" next to the switches. If you figure it out, please do tell me. Those little switches, with the red buttons may need to be replaced.
    • It says 300ZX, does that make it an Aus delivered car? Funny how back in the day I just couldn't care less about Z32's and these days I am just in love with them. Back when Nissan was into pushing the envelope. 🤣
    • Hi guys, just after some guidance with an R34 sunroof that has stopped working correctly. It still opens and closes perfectly fine, but it no longer tilts/vents up or down. As a result, the rear of the glass now sags a bit as it drops down slightly in order to retract into the roof, but now it can't pop upwards into a flush position. I’ve probed the pins on the back of the switch connector with a multimeter and it seems like both switches (for open/close and tilt/vent) still work correctly. Any ideas on what it could be, or where I should even start in terms of diagnosing? I'm sure someone's had this issue before but I haven't been able to find anything online relating to this specific issue, most of the issues are with the seals leaking or the motor failing entirely. Thanks in advance!
