yeah sounds a bit too high, my 34 with exhuast, fmic, ~9psi, pod makes 185rwkw, so id guess on 11psi ish youd be at 185rwkw-190rwkw. how have you achieved that boost increase?

Jeff at turbo tune said something on the lines of the stock solenoid has a high and low setting. Mine started at 6 psi and then made its way up to around 11.5. When I get the dyno sheet scanned you'll see where the boost increase will be.

auto salon was dead on actually. i had just got my car dyno tuned at boost worx a week prior and it made 2kws more than it had been tuned for.

anywho.. i dont find it hard to believe 200. i mean 11.5 is lot of boost for a rb25.

The Autosalon dyno was the Graham West dyno, yeah?

correct cronic.

Zak, yeah you've got a real gem of a 33 there, seems your fmic and exhuast is working very nicely with your engine.

And Steve, i was just asking how he achieved the boost increase, a jump to 11.5psi from just minor mods isn't seen too often.

yeah i edited that, it came out completely wrong lol. 6psi sounds like a fair gain in boost, i wouldn't mind having mine looked at. Guess i'd start with hi flow/no cat and removing the restrictor.

201 is a too me sounds about right.

i made 205 with the same sorta mods when i had me ebc fitted and set at 11 psi...

got alot more now though :P :P

he wont be able to add it now Dale, you have 10 mins to edit your post unfortunately. Has a nice increase at 150kw's, Jumps to 170!

I think you'll find that that is AFR related. the factory maps are a bit all over the place as they are only tested at certain points in the rev range not over the whole range. So at the points were they are tested they have good emission's and every where else it's tuned for safe power.

Zac has an SAFC II in the car but it hasn't been played with at this stage and has 0 correction factor at every point so when he takes it to Jeff next the AFR's will be more constant and there will be a bit more power (~10kw).

P.S. thanks for letting me know about the editing time, I never could figure out why you could edit your post some time but not others. On NS where I do most of my posting you can edit it any time. I guess it pays to be a post whore on more than one forum.

wheres the Dyno settings at the bottom Dale

i thought it was more like 30mins editing either way we need editing rights

I'm not sure where the info is, I just checked the printout and it's not on there.

But I also looked at the printouts for my car that were done on the same dyno and there aren't on there so it might be the way TT have there printouts setup. I would say the the temp are correct because every time I have seen Jeff drive a car on the dyno the first thing he does is enter the humidity and temp from the weather station they have setup next to the dyno.

Ive been in and driven IZZMO 33's car and it feels very much like 200+rwkw with minimal mods aswell..very impressive.

to me that dyno is reading a wee bit too high

i had my car dynoed at Willall Racing and they use a mainline dyno

with a front mount, boost increase to 9psi, full zorst, splitfire coilpacks, pod....my car made 188.7 rwkw on a reasonably warm day

so from the mods that you are saying you have i would expect the same sort of power that my car has pulled out

plus no boost controller and ur hitting 11.5psi....umm have you had that reading out off a boost gague or from the stock gauge.

My R31 with series 1 rb25det and my r33 with series 2 rb25det both made 203rwkw and 205rwkw with 10psi, cooler and exhaust on a few different dyno's give or take 3-5kw

You WOULD have about 200rwkw if there was an aftermarket computer or your ecu has been remapped........

not necessary mate. Every car is different.

over 30 posts and no one has mentioned ramp rates.

how much brake against the rollers.........you need to compare apples for apples

God dam it pete, you beat me to it! hehehe

People dont realise that its up to the dyno operator to choose the specific ramp rate that the dyno produces...this alters your power output...usually a standard ramp rate for these things is around 150.

So many people are quick to assume every car is the same and will make simular power with simular mods. Every car is different. So many variables come into play when it comes to output on a dyno...remember people its just a number.

oh and i forgot to mention we've had plenty of 33's on the dyno at Aussies and alot of them make good power (190-200rwkw) with basic mods yet others make average power (160-180rwkw) with simular mods...SO many variables. Believe it or not other cars have had a much harsher life than others.

    • Haha, i kow right? Could have bought so many cars for the same amount of money (or less) but driving Unicorn gives you at least +1mln to style 😅. Like wise man said "life's to short to drink cheap wine and drive boring cars" 😉
    • Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny  
    • Hey all  im wondering if you can help me please I have put a rb20 box in my r34 gtt as my auto packed up and a friend had a spare box I know it’s not ideal but it will get me up and running for now. we have done the conversation and everything is working great but my Speedo we got a s13 speed sensor but my Speedo reads double now and I bought a speed converter but still not having any luck.  so I thought I’ll reach out and pick your brains  any help would be appreciated please as I wanna drive my car again 
    • Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.
    • Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
