im pretty sure my timing was off.

i posted a dyno graph showing the before and after curve.

so just to clarify, i got 147 on 3" turbo back, fmic, pod and 12psi

with retarded timing (i THINK it was sitting a few degrees under stock).

if my timing was spot on then im guessing i would've made around 160kw as my base. but you cant really tell.

also another thing i'd like to add is he said that sometimes the knock sensor on the safc screws with the timing, if the knock is high then somehow it will retard timing so he advised me to disconnect it.

My GTS-T (5 Speed) made 160rwkw on the dot with a front mount intercooler, pod filter and turbo back exhaust running 10psi, anymore boost that that and the factory ECU seemed to retard the timing

You mean to say you disconnected the knock sensors ?

:P my gts-t r33 s1.5, has got 3" front the dump pipe, boost controler set at 11psi (i set it to 10psi once and it did run alot nicer) pod, and thats about it, and its getting 194.9rwkw :(.. stock intercooler, stock ecu as far as i know.. wots with that? how come so high.

dont get me rong, i dont mind, just wondering if there could be other mods that arnt so ovious that may be helping it get so high.

p.s: on stock boost (7psi) it was at 170rwkw :confused:

As I understand it, the power figure I managed (which was taken on C & V's dyno) - was pretty much spot on for an RB25DET with the modifications I had at the time.

Varying dynos give varying results - I dont believe you almost reached 200rwkw from an exhaust system and 11psi, sorry.

Its weid people are posting results at ither 160-165rwkws

or 185-195rwks with the same mods

i must addmit us autos 4 in this thread all push 185rwkws and all in second

i was told my turbo was hiflowed cause i pushed alot of hp but i realy dout it now cause we all push the same

confused james

yeh i was i was a bit like, woh ok.. im just wonding if there has been other mods in the engine that i cant see (im not a car wiz so i only know from what ive picked up here)..

got it done at UAS in castlehill.. they do alot with skylines and 300's, so id wana think the dyno was pritty close for thouse type of cars

red line on low (7psi), blue on high (11psi)

Blitz is 100% correct. Not possible to get 50rwkw with a air fuel controller. If that figure was with a power FC i would believe it not with SAFC.

By the way i like your intercooler setup, looks great!

like I said, his base timing must have been way off.

Look at the original graph. Power curve looks like something a 3 year old would draw. I've only ever seen graphs like that with severely retarded base timing.

Does it matter what gear the dyno tune was done in... I'm asking as the tune for my car was done in 3rd (tiptronic), just wondering if doing it in 2nd would've made a difference.

I've been reading with interest too. I'm getting dyno tuned tomorrow with a Jaycar DFA (works the same as SAFC)

I'll definately ask the tuner to check my ignition timing. Excuse my ignorance but is this a quick easy to do (adjust timing) because I only booked in for an hour.

I got similar mods - 3" exhaust, pod, 10psi, stock intercooler - chugs fuel

5 Minute job

how can you guys argue with whats written on paper?

and i keep saying he didnt only tune my safc!

Your totally right.

Heres a dyno result from an R33 GTR in essentially stock form - I know it might seem a little high, but how could you argue with it? After all, the owner has it on paper

so what you're saying is ive completely fabricated the dyno?

thats f**king stupid.

you're making accusations you cant back up.

    • I know this one’s the BB one. My tuner did make mention about the actuator. I am curious about the VCT as well
    • Might also needs a stronger actuator with the right preloading. With older 2019 built bush G3 units, BB upgrade or 21U housing down size makes a pretty decent gain in response as well. 
    • Hey lads  so im finally putting together my rb30 forged bottom end and ran into an issue. I measured my main bearing clearance with arp main studs torqued to 60 ft-lbs using ACL H series STD size bearings and standard, un-ground crank shaft journals and got an oil clearance reading of about 1.3 thou measuring straight up and down and about 2.8 thou measuring at a 45 degree angle (just above and below the parting line). My machine shop said they measured the main tunnel and it was all within spec (they didnt say the actual measurement) and to go with a standard size bearing, which i have done and the clearance is too tight, I'm guessing because of the extra clamping force from the arp studs distorting the main tunnel. I was wanting to run about 2.5 thou main bearing clearance.  My questions are: 1. could i just use the HX extra 1 thou clearance ACL bearings? that would fix my straight up and down clearance making it about 2.3 thou, but then would the side to side clearance be too big at around 3.8 thou? 2. what actually is the recommended main bearing clearance for measuring near the parting line / side to side. i know its supposed to be bigger as the bearing has some eccentricity built into it but how much more clearance should there be compared to the straight up and down measurement? at the moment there is about 1.5thou difference, is that acceptable or should it be less? 3. If i took the engine block + girdle back to the machine shop and got them to line bore the main tunnel (like i told them to do the first time, but they said it didnt need it) what bearing size would i buy? the STD size bearing shells already slide in fairly easily with no real resistance, some even falling out if i tip the girdle up-side-down. If im taking material out of the main tunnel would i need a bearing with extra material on the back side to make up for it? this is probably confusing af to read so if something doesn't make sense let me know and ill try explaining in a different way. My machine shop doesn't come back from christmas break until mid January, hence why i'm asking these questions here. TIA for any help or info 
    • I bought the model back in Japan in Feb. I realised I could never build it, looked around for people who could build it, turns out there's some very skilled people out there that will make copies of 1:1 cars or near enough. I'm not really a photo guy... but people were dragging me in a group chat for the choice of bumper as someone else saw the car before it was finished as they are also a customer of that shop. I took the photo in the above post because I was pretty confident that the lip would work wonders for it. Here's some more in-progress and almost-done pics. It gives a good enough idea as to what the rear looks like!   I have also booked in a track day at the end of January. Lets all hope that is nothing but pure fun and games. If it's not pure fun and games, well, I've already got half an engine spare in the cupboard 
    • Well, do ya, punk? Seriously though, let's fu<king go! The colour and kit looks amazing on the car. Do you have any shots from the rear? I don't quite follow how the model came around. You bought the white kit and he modified it to match your car? Looks nuts either way!
