Dyno Result - Normal Or Too Little?

Hi everyone! had nistune installed onto my r34 (Neo engine) with auto tranny and the dyno results showed 233hp (12 psi)at the wheels.

I have stock turbo and engine, 3in exhaust with 3.5 catback to cannon. FMIC, air filter, EBC, custom oiler cooler and radiator, HKS BOV. Now after seeing everyone's postings on their dyno results, im thinking is my results too little?? 233hp whereas similar setup, the other guuys are getting at least 210rwkw. Im not sure if there is anything wrong

2ndly: My aim is about 400hp atw and I am going overseas where I will be able to get my hands on parts at a relatively cheaper price so wanna get some advice on what parts i should get. Roughly, im getting a upgrade on my injectors(500cc or 600cc?), fuel pump (bosch 044) and a GT-RS turbo. is there any other recommendations from you guys on what i should get to achieve that aim? Reliability is my top priority as it is my daily car. :cheers:

boost peaks at 12psi cos i have been reading alot that for the stock turbo, the safe tune would be at 12 psi. did thought of pushing it to 14psi but wouldnt want the turbo to die on me too soon thus had it at 12 psi. you reckon its safe to have it at 14 psi? but i dun thrash the car all the time by the way.

yeah he said he had a nistune remap.

Sounds about right, i've got a 34 neo with nistune, split/dump, stock turbo with r32 actuator set at 10psi and getting around 170rwkw. It's begging for more boost though.

200rwkw @ 12psi is where it should be. +/- 15rwkw for dyno differences and you really aren't too far away from there and you are running through an Auto so sounds spot on overall

Best way to tell is at a dyno day really, everyone on the same dyno, same day is the only real decent way of telling if your tune is low on power easily.

You can compare maps/timing and so on but each car is different so it become tricky.

As for 400rwhp/300rwkw, a GT-RS really isnt going to get to that. I think there was one or two cars that made that figure and no-one elese has come close so probably high figures as most seem to make closer to 260-270rwkw which is about the limit i'd push a stock motor anyhow.

Plenty of threads on 250/270/300rwkw setups, so have a search around

well, could be the auto box losing another 10-15hp for me. well, after spending on the nistune and ebc, i really was expecting about 240 hp. (215hp prior to installation but has a really shitty AFR) 180kw was a tad little disappointing. but oh well, since im not too far away, i shall keep working towards it. will be getting another turbo, injectors and fuel pump when i go for my hols in feb. will see how it goes. but shd be getting a high flow cat next week. will scan the dyno paper tomorrow at work and let you guys have a look.

      Are you an oil nerd?

      I think the concept is highlighting the various scenarios where thicker oil helps, and thicker oil potentially doesn't help and only generates heat and costs power, in turn for safety which isn't actually any safer (unless you're going real hot). If anything this does highlight why throwing Castrol 10w-60 for your track days is always a solid, safe bet.

      Jason should have shown a real viscosity vs temp chart. All the grades have very little viscosity difference at full operating temperature.

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      Yep, if you are applying filler it sounds like there is something wrong with the body lol. Safe to assume there is going to be a lot of sanding going on if your still applying fillers.  Picture a perfect bare metal panel, smooth as glass. You lay down your primer, it's perfect. (why are you going to sand it?) You lay down the colour and clear, it's perfect. No sanding at all took place and you've got a perfectly finished panel.  You won't be chasing your tail, sounds like you were prepping to start laying filler. If your happy with the body after the sanding, there is some bare metal exposed and some areas with primer, no issues at all, start laying the filler. You are safe to lay filler on bare metal or primer (of course check your technical data sheet as usual for what your filler is happy to adhere to).  This isn't a 100% correct statement. There is primer that is happy to adhere to smooth bare metal. There are fillers that are happy to adhere to smooth bare metal. Just make sure you're using the right materials for the job.  Typically if you are using filler, you would go primer, colour and clear. I've never seen any instances before where someone has laid colour over body filler (maybe this happens, but I haven't seen it before). So your plan sounds pretty normal to me.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I don't think there's any way someone is push starting this car.. I honestly can barely move it, and moving it and steering it is just flat out not possible. I'm sure it is, but needs a bigger man than me. I have a refurbished starter now. The starter man was quite clear and consise showing me how nothing inside a starter really should contribute to slow cranking, and turned out that for the most part... my starter was entirely fine. Still, some of the wear items were replaced and luckily it didn't show any signs of getting too hot, being unfit for use, etc. Which is 'good'. I also noticed the starter definitely sounded different, which is a bit odd considering nothing should have really changed there.... Removed and refit, and we'll pretend one of the manifold bolts didn't fully tighten up and is only "pretty" tight. GM only wants 18ft/lb anyway. I also found a way to properly get my analog wideband reading very slightly leaner than the serial wideband. There's Greg related reasons for this. The serial output is the absolute source of truth, but it is a total asshole to actually stay connected and needs a laptop. The analog input does not, and works with standalone datalogging. Previously the analog input read slightly richer, but if I am aiming at 12.7 I do not want one of the widebands to be saying 12.7 when the source of truth is 13.0. Now the source of truth will be 12.65 and the Analog Wideband will read 12.7. So when I tune to 12.7 it'll be ever so slightly safer. While messing with all of this and idling extensively I can confirm my car seems to restart better while hot now. I did add an old Skyline battery cable between the head and the body though, though now I really realise I should have chosen the frame. Maybe that's a future job. The internet would have you believe that this is caused by bad grounds. In finding out where my grounds actually were I found out the engine bay battery post actually goes to the engine, as well as a seperate one (from the post) to the body of the car. So now there's a third one making the Grounding Triangle which is now a thing. I also from extensive idling have this graph. Temperature (°C) Voltage (V) 85 1.59 80 1.74 75 1.94 70 2.1 65 2.33 60 2.56 55 2.78 50 2.98 45 3.23 40 3.51 35 3.75 30 4.00   Plotted it looks like this. Which is actually... pretty linear? I have not actually put the formula into HPTuners. I will have to re-engage brain and/or re-engage the people who wanted more data to magically do it for me. Tune should be good for the 30th!
