My car was also tuned at Ice Performance very good service which is hard to find these days. Mods and power are in sig Nigel said the car is making very good power and usually it would take more boost than 10.5psi to make that power. Unfortunaty I lost the graph and im not sure whether it was done in shootout mode. i would highly recomend ICE performance to anyone.

The long awaited dyno graphs! please post your opinions.

The graphs dont look anything to special, but the opinions from both tuners at those places is that they reckon there MIGHT be something tricky about the turbo. From what I know when i imported this vehicle that it was stock :confused:

http://members.dodo.com.au/paul/pics/dyno/172rwkw.jpg thats my latest graph

all through the rev range your about 5kw or thereabouts above until 5500 where your about 15kw more than me. if it wasnt stock i'd expect more lag or a bigger jump up

heres my little graph, i've got a question also :)

the AFR:P on the right on all our graphs, I know what it stands for but whats it actualy mean ?

Like mine is 18, pauls is 20, and nitemares was 24 but what does that mean exactly ???

There are some rare Nismo Prep GTST that have made it to Australia. Apparently they were made available from Nissan and have a higher compression engine and a modified Turbo.

A Friend had one and has the details if you are interested.

Check your PM for his number.

the AFR is air fuel ratio. its showing the af ration from 10 upto 20:1.

20 being lean and 10 being rich. 10 parts of air to 1 part of fuel = less of a bang + wasted fuel

20 = big bang and less wasted fuel. the main climb curve is power going up (you measure against the left axis) and the wonky line that hovers near the bottom of the graph is the AF curve (you measure against the right axis). so going by yours justin it starts off at 12.5:1 and then hovers around near 12.0 which is the ideal af ratio. not too rich and not too lean but lean enough to get some power and keep the engine safe

well my understanding off af and lean / rich. i could be wrong hope im not. if iam can someone please correct so i get it right next time

thanks

if on your graph justin that lower af curve skewed up to the middle of the graph towards the end to say 14 ish then it would say the car is leaning out too much. perhaps car is not getting enough fuel etc or something in the fuel system is maxing out as an example. its pretty much on 12 all the way through so its pretty good and the ideal af it is :)

Well now im interested to hear ur opinions. Should i fork out some cash and do some r&d to find out what i actually have, or in your opinions is it defintely a stock turbo, which perhapes has had a fairly easy life so is generally making quite good power.

I'm also curious as to how you've gone wiht ur split dump-pipe paul, and was it actually worth doing. I'm just wondering if its worth getting a new dump pipe, given that theyre gonna have to take it off anyway to check the turbo, if i do take that road.

just on a slightly related topic :cheers: I tried to do that a few weeks ago, when i heard something make a metal/metal grinding noise. How do yo take off that pipe which connects to the air filter... im guessing thats the front pipe ??

jus read the thread. just thot id share my results too.

    • Hi guys my 94 r33 gtst fuel pump has gone out. I have a walbro 525 ready to go in but am unsure if I need to upgrade the fuel tank bulk heads? Ive heard that others have issues with the stock wiring melting... Ive seen alot of people recommend this: https://frenchysperformancegarage.com/products/fpg-nissan-skyline-r33-r34-silvia-s14-s15-billet-fuel-tank-bulkhead-hat-top-an6-with-high-current-connector-apex-2-8-delphi-fpg-100?variant=42873255198898 My current pump that stopped working is aftermarket but I had no relay mod or upgraded connectors. Need some advice please. TIA
    • It’s new. It’s the cd009. I did take the transmission apart to mill down the bellhousing and had both housings come off the gears so wondering is something isn’t in right. I am running redline. I can get it in gear running too but it’s just not easier and it’s almost like 2, 4, 6, and reverse all the back gears aren’t happy going in
    • I’ll remember that as a last choice. It’s brand new
    • Got keys and did a walk around the yard planning the landscaping works with the family that I will be doing Main effort: remove all the woodchip in the gardens that are around (attached) to the outside of the house and replace with 10mm blue metal, having woodchip close to the house is a recipe for inviting white ants, currently there are no white ants within the block and I would like to keep it that way I'll be buying some large raised garden beds to grow veggies and stuff, and the woodchip will be mulched with everything else that gets dug up, pulled out, or cut down during works Next will some minor drainage and landscaping maintenance up one side of the house, where the fuse box, AC, and solar stuff will go, about 12 mtrs long by 2 meters wide, I'll break up the soil, add gypsum and then I'll dig in a French drains about 300mm deep x 300mm wide and fill it with agg pipe and blue metal, then level out the whole area with a 50mm layer of blue metal, the soil, whilst currently pretty compacted, will break up well with the gypsum to aid in drainage, I'll then cover the area with a 50mm layer of more blue metal In saying this, the drainage issue is minor, but that little hidden away area down the side is untidy and weedy, and as all of the main elec stuff is there I want it neat and tidy to appease my OCD Again, the material excavated from the French drains with be added to the garden bed mulch, as will some rose bushes and some other crap looking garden plants, and a old apricot tree that is looking worse for wear The apricot tree is currently in a little roundish garden bed that is in the middle of the back yard with few other crappy looking plants around it, that will all be removed, levelled, re-turfed, and is a perfect spot for a hills hoist There is also a area about 3m x 2m between the rear fence and shed that will get some attention, it looks like some stuff was stored there and the grass is dead, that will also get broken up and mulched, and is a prime spot for a pumpkin patch I've guestimated that I'll need: 3 tonnes of blue metal, 12 meters of agg pipe, 5kg of Gypsum, and a hills hoist, so a few bags of concrete as well to set it in place (the house currently has one of those pull out 4 line jobs, whilst it works, I want a retro old school hills hoist), I am also going to run some chickens, there's a great spot for a coop, so a chicken coop to suit 4 of those lovely egg laying bitches will also be on the job card That should keep me busy for a while, and will finish off the back yard ready for a early spring planting of some veggies and berries  Once the main effort is done I'll start out the front, there's a large rock garden that could use some TLC, but that is only minor works Should be fully moved in within 2 weeks, the landscaping works will start then Fun times, retirement is good  
    • It happens, that's what your single stage filler is used for.  If it is still visible after the 3 coats of 2k primer, it will be visible after the paint is laid down.  Its hard to give 100% perfect advice without being there in person, I'm very tempted to say stop where you are, fill your pin holes with a single stage putty first then keep going.
