I know I'm not NSW but what is happenign with this? I have seen exactly the same manifold at Autobarn here in Adelaide, so is it a GCG one?

Looking forward to it for sure, but What's, your right, gotta be some favouratism thrown in there.....can't have these bloody last minute ring-ins "winning" :thumbdwn:

Excellent mate, a bit of brains and thoroughness makes the difference eh.

Shit, sounds omminous!!

Garretts run fine at high boost. Thanks B-Man for info.

Love it B-Man, good power. Do/will you have power runs at lower boost pressures, say 14-17psi for daily driving etc? The reason I ask is that I have a hybrid internal gate Garrett GT3040, which has a slightly different exhaust wheel to HKS as well as 0.60 A/R comp and 0.63 A/R exh, but otherwise sort-of close. I get 265rwkW at 17psi with all other engine bits totally stock. Would be nice to know your power at LOWER boost as it might help me predict what might happen when I boost it to 20-22psi later with other bolt-on stuff optimised, like exh manifold, cams etc. Don't want to push it just yet as I have stock pistons. Also do you ahev stock cams? If so, 323 is awsesome.

Not sure about your problem mate but back to the 4WD vs 2WD dyno bit, you should be able to remove the FWD fuse to make it RWD only. I think that's right? So you should come along and throw it on.

I am not entirely wrong ... dude. I basically said the same thing that you have just said. Maybe better explained with two scenarios: 1bar boost at 5°C 1bar boost at 50°C (as would be seen in circuit racing) AFM ECU - fueling different for each situation to give same A/F ratio (dangerous maybe??? and no way to change other than with across the board richening up to cater for hot situation) MAP ECU no t. comp. - fueling same for each. Hotter situation would have richer A/F ratio as ACTUAL density is lower but fuel same (inherently safer????) MAP ECU with t. comp. - fueling different for each situation but entirely tunable (if you are ever able to tune across that temp. range)

False logic maybe. If the AFM senses a lower density due to hotter air, then it will deliver LESS fuel for the same throttle position. So you are effectively saying for PFC if the air temp rises your fuel mix will correspondingly become LEANER. If this is the case, it's OK for Nissan to have this situation as the A/F mix is SO rich anyway there is plenty of room to move. Liek Roy said, why do one of the best engine series not use AFMs and use MAP sensors instead....that is the 1JZ and 2JZ series....I don't know why but an interesting point. Look, I'm not saying AFM are worse, I just think it's much of a muchness between the two but I have heard from one or two tuners that one of the PFC's weaknesses is the lack of temp compensation. Otherwise a good ECU.

OK with me.

In!

Who's yellow R33 did I see at Artini crash today...in a very sad state!?! The guys said it had only just been fixed up in November from another crash.

www.microtechefi.com Might offer more insight. I have had LT12 for 18 months and I'm happy with it. New LT12S and LT16 have much much better processor than most, but about same power as MOTEC. Both systems have the same processing power but the 16 has masses of inputs and outputs for proper professional racing stuff, just like MOTEC. Tim at RPM has just conducted an intial shakedown test for the LT12S on the old JMS red 33 that had a PFC and its looking good.

Steve, see Clint32 re adjustable arms.

Well nothin TOO fancy for me in rear end: King spings (progressive) Bilstein shocks (used to get heaps of axle tramp at AIR when at 200rwkW but now none) Superpro offset/adjust upper-arm polyurethane bushes (they give me 1° camber, up over 2° without which is too high for street applications) Whilteline non-adjust solid swaybar "Clint32" HICAS lock (not bad for an R32 scrubber ) Rear tyres are 265mm ZE326, nothin special but hook up surprisingly well at AIR, although not as good as RE540s. I reckon Bridestone in Gouger are the best for wheel align but make sure you get a bloke that knows hi-po stuff now that Laurie has gone.

I think all is now in order, are boost pressures right? Will be better on the same dyno, Grepin's had a stronger mid range on the Boost Worx dyno compared to Tilbrook's. EDIT: Oh yeah, kept the pink one for ya Matt, nothing else looked right! Also made changes at 90km/h.

OK, will do more accurately plus with Whats's 19psi figure instead, something to aim for.

OK, more composite dynos with Steve's additions. The chart isn't exactly right re curve but gives a good idea. Will be good to see some the RB20 & RB30s on the same chart.

What a bunch of R32 floggs! Gotta be wankin yourselves! :thumbdwn:

I've got one, I'll sell it to you for $5000 if they are that rare :wassup:

Anyone?

Gotta alot things on my plate at present so have stalled the cam upgrade. Woudl be nice to have a look at a better exh manifold with it, so $$ start adding up. I have 400R bar to go on next week and that is more $$ so motor stuff will wait a while. So yeah, not sure if top end torque power drop off on mine and yours is stock exh manifold (Grepin has nice manifold), EDIT actuator spring (Grepin has HKS actuator), int wastegate design (Grepin's HKS int gate exh housing is also very nice)......good to see you're trying one. I mention Grepin's stuff due to the strong power curve right up top. So fit and tune with Apexi actuator tomorrow?

Just for interest sake, here is a composite dyno of Grepin's, mine and What's. Grepin's is on different dyno. Shows the different power bands of each motor pretty well:

We won't get into that argument, it gets ugly as people become very sensative to whatever ECU they have bought (I have Microtech and it works well). Better to do your own research ALL ECUs and make up your own mind. There seems to eb this myth that the PFC is the be all and end all for R33s. They are just like most other programmable ECUs, with ALL having dissadvantages and advantes over each other. Matt, great numbers and I also agree re Microtech, I asked Shaun to do a Valet map a while ago but in all honesty I could have done it myself, they are so easy to do and then save onto the next spare Memcal. I know because I accidentally overwrote Shaun's Valet map and had to do it again myself :Oops:

Turn it up! Great stuff Matt, you'd be very happy with that! Very timely re 4,6 & Rotor shootout. Your turbo is smaller than mine so that power at that boost is excellent, interesting to see what timing Shaun was able use safely. When are we gettin some other scrubbers on the track!?! Plenty of cars with good power that can get into the mid 12s now.
