you said a stock exhaust now you said just cannons.. you said everything else stock then you said you also have a pod
Looks like one healthy motor, The boys (presume Mark did the tuning) really know there stuff Gotta admit, I'm not really surprised that you pulled those numbers on stock coolers and exhaust. You might find that the guys commenting might be right about having Hi-Flo turbo's though??? Just fuel for thought Obviously it was tuned on 98 fuel, don't suppose you happen to know the timing and A/F ratio he tuned it to?
that is a VERY impressive number. few things to make this feel ALOT better again which i think you should seriously look into. do you feel the peak in power and then it just feels like its not pulling after that thru the rev range. well first thing is upgrade ur coolers, the stock ones have known (i dont know if tested) to be efficient up to about 14psi... next is your exhaust, you mentioned u have rear cannons so im guessin u prob have a catback system. look into upgrading the whole lot. up to you really if you want to upgrade the dumps right now, but id atleast upgrade everything past the dumps. incl test pipes, cats, etc... with these additions and a new tune, your main change will be consistent power delivery throughout the rev range instead of it tapering off like it does which is alot... some power is to be made, but ur car will feel better still even just fixing up that drop off from the additions. you already have a pod so thats good. apart from that excellent result man... hopefully you have already done the 100k service, and the cooling system. if u havnt get onto it quick smart. you might be pushing these old components to their limits if they have no been changed... 100k kit would be excellent
so im gathering with nistune,all you need is NIStune real-time daughterboard around 200,then take it to a licensed tuner,he solders it in and tunes it on the dyno ???? From what i read and briz said,A nistune board is $200 plus about $150(although i think its more like $40 by a licenced shop) to fit, plus 4 - 5 hours on a dyno at $150 equals $950 - $1150
Status tuning (http://www.statustuning.com/) were doing a deal for SAUVIC members. Roughly $750 installed and tuned (they supply and fit the nistune board). The tuning time is not set, Trent will keep the car until he is happy with it. So it may be 5hrs, or might be more than a day. Was considering going nistune, but I think it's more suited for cars that are getting parts added that require slight tweaks to the tune which can be done easily through the consult port.. whereas my car will be tuned and that'll be it, so probably better for Bob to do my car.
In Response + Info thanx everyone for the support and good feedback. others, yeah you know. and when i say STOCK i mean engine is completely STOCK - i rebuilt myself parts supplied by Caz1 (Caz Racing) - block, pistons, rings & crank not touched (were perfect) reason for rebuild blown head gaskets just got heads machined to put back on. used complete rebuild kit + 100k kit engine like new except for internals stock turbo's rebuilt under warranty through precision turbo's not ball bearing - original stock radiator (temp's always between 78-83) full pressure flush and clean driveline not touched (manual gearbox, diff, tale shaft - still stock) didn't even service them just left as is removed egr removed aiv under plenum water bypass tried to get stock injectors cleaned by professional cleaner, but called and stated he could not clean or service, already in perfect condition stock coil packs stock flywheel, no underdrive pully like i said engine stock i only have changed or after market hks pod filter hks ignition amplifier (was not in car when dyno run, it broke few days ago before dyno) cat back with canons sard fuel reg apexi avc-r atlas boost controller so how did i get these numbers ? 1. i'm no mechanic yet with my magic touch i rebuilt and put together 2. parts were special blessed parts via Caz Racing 3. Mark really knows what his doing 4. all of the above 5. i faked it (i would have made higher if i faked it) answer well it was 4, with my magic touch with the added support from Caz1 (Caz Racing) with supplying all of the parts i needed to rebuild my car & alot of info, then Mark just fine tuned it and produced them magic numbers. my next upgrades will be (to even out power throughout rev range) front mount plasmaman inter cooler nismo lower temp thermostat 3 inch full exhaust dumps ?? never thought about it, need to check if i can get better dumps on stock turbos I would like to give a BIG Thank You to Caz1 (Caz Racing) for supplying me will ALL the parts needed to rebuild my engine/car plus all the info i needed & to Mark (MRC Dyno) for doing a fantastic job on tuning my car. Thanx Guys heaps, car runs like a dream.
Stage 3... Nice result. A healthy stage 3 zed would pull that number, so it's about right. You've have it tuned on the dyno and you're running high boost for stock turbo's, so yeah. Very healthy result, you should be happy. NIStune seems to do the job nicely actually... A word of advice though, if you're planning on running that kind of boost, you should really upgrade your intercoolers...it's gonna get hot under there...the stock ones could be robbing you of a few Kilowatts too...so your result could go higher yet... Well done. Cheers Rob.

2 Cents worth Firstly congratulations on the figures ... 250rwkw is the maximum for what I would expect for a semi-standard zed with your mod list. Looking at your dyno graph and the initial start of the curve with the bit of lag I believe that you might find that while externally your turbos are standard I think you will find that you have hi-flow internals. Plus exhaust is not standard which is often a biggest killer of power. By the way I get my car tuned on the same dyno, and it is professionally calibrated each year (hence the Dyno Dynamics accreditation), and Mark knows his stuff. On my VH45-NA the Nistune made a significant performance change from 180kwrw to 198kwrw (i.e. 10%) only by advancing the timing to take advantage of 98 octane fuel (compared to the original 91-93 octane from 1990), and leaning off the engine as Nissan likes to flood the engine when it is under high revs and load. For a V6-NA of appropriately 120kwrw I would expect 132-135kwrw with a Nistune.
Stages... The general engine upgrade stages... Stage 1: Air Intake (Pod Filter) Stage 2: Catback exhaust Stage 3: ECU upgrade + Boost Controller Stage 4: Larger Intercooler(s) Stage 5: Dump Pipes + Hi-flow cats / Underdrive pulley / Lightened Flywheel Usually if you're around Stage 6+ you have larger turbo's, injectors etc...then it starts to branch off from there with internal engine parts etc... But the majority of Zeds usually have these first 5 stages covered...and it's common for all. At around stage 3, running 16psi, you should be achieving somewhere between 230-260rwkw depending on condition of engine and the tune. His engine appears to be on the healthy side. Cheers Rob.
the whole stage thing to describe mods = fail. completely ambiguous since what is defined as a "stage" varies everywhere. take this one for example. a pod counts as one stage? LOL then stage 5 includes underdrive+flywheel AND multiple exhaust items? riiight that's well balanced. i can't see the point in it. granted it might sound cool telling newbs your car is stage 9 phase 11 or whatever but to anyone else it just sounds try hard. back on topic... what AFR is the car tuned to?
Notice how the AFR levels out at just over 12 Notice how the AFR levels out at just over 12 (between 12 and 13). On the factor OEM ecu this is where the line keeps dropping due to protective flooding with fuel. It is the flattening of the AFR curve that results in the additional top end power (plus advancing the timing). Well that is my 2 cents worth.
peak power at ~5150rpm......nice heh. What was the timing set too? How much boost did you run? Was it on pump fuel? Is that a daily driver 252rwkw or a once of dyno tune run? Cause thats big power for what is described above. Nevertheless still yours and lookin good
