Hi guys,

Had my 33 on the dyno for the first time the other day, trying to sort a problem with a flat spot/hesitation around 3000rpm. It was showing 155.8 rwkw @ 6750 rpm. As far as I know, the only mod to the car is a cat back exhaust. Does this power figure seem accurate?

I am also interested to know what the rwkw figure is for a stock r33 if someone could tell me.

Also I have run out of ideas with what might be causing the problem with the car. It usually only happens when the car is cold, and only around 3000rpm. Happens inconsistently and mostly if you shift up a gear to 2500rpm and then accelerate. Everyone that has seen it says that it is not the coils, and the guy that dynoed it says that he thinks it might be a partially blocked exhaust becuase the car is very quiet.

Any suggestions?

Nick

hey dude, you copying me;)j/k

it may just be your plugs... my car had a miss on the dyno due to fouled plugs (apparently octane booster and platinums don't agree with each other)

If it is just the odd miss here and there most likely to be some kind of spark/ignition problem... wouldn't worry about power output... if anything 155rwkw sounds a bit on the high side

Geez, names are pretty close aren't they!!

Plugs are iridiums I got from Nissan. Don't think they are fouled at all.

Problem was really bad this morning. It is hard to reproduce on the dyno and is mainly when the car is cold. It is as if it is coming onto boost and then it just goes jerky and loses power for a second or two, then goes fine. Change gears and it does it again. Once the car has warmed up, it seems to run fine.

Interloper - Got the car dynoed at Geelong Tune Up by Phil. Which side of geelong are you from?

Why cant you just wait till the car has warmed up? You're supposed to warm the engine up first anyway, otherwise you force unnecessary wear on the internals.

It could be the plugs tho. Iridiums are only good for durability. Copper plugs have a bigger head (so they produce a bigger spark), copper is more conductive than platinum/iridium (so its easier to get a spark), and they self clean (carbon deposits have a higher affinity to bond with platinum/iridium). Only problem with coppers is they need to be changed every 10-15K km.

Interloper, Where abouts in Leopold? I'm from Leopold as well. My line is the burgandy R33 with white rims. Geelong Tune Up is in Wood St, South Geelong. I get all of the servicing/normal work done by my Dad or do it myself, cause Dad has his own workshop in Crown St, but he doesn't really go into the performance side of things at all. Whats Dalton like? I've heard he's pretty pricey.

RiggaP - I live right near the highway. Only 800 metres of driving and then I am on the highway, so I need to get to 100 reasonably fast, wouldn't go past 4000rpm until it has warmed up though.

Don't think it is plugs cause it was doing it before I put Iridiums in. When I first got the car, it wasn't doing it though.

would like to stay off boost, but there are a lot of cars on this particular highway. And it is only 2 lanes wide so at 8.20 in the morning there aren't too many gaps!!!

Remote start would be nice! Especially since the car lives outside and is pretty cold in the morning!!

Hey, me too i live about 800m from bellarine hwy and use the remote start before i get going in the morning cause its a pain getting upto speed on a busy morning.

But i don't really give a sh1t, i just take my time to get to 100 - who cares if you hold up a lane of traffic? the well being of your cars much more important :P

I live just off melaluka, off cypress cres. Where abouts are u?

Dalton is good, they charge much less than shops in melb, but they don't have a 4wd dyno. But i usually take the line to melb to get work done - RiggaP knows...

      M35 Brake caliper replacement

      By Waders360 · Posted

      Hi from Canada, Both of my calipers are starting to fail. My car is a 2005 M35 Stagea ARX and I can't seem to find any parts or any cross reference caliper that would fit my car. Is there a company or a similar caliper that would fit and I could replace the OEM one. Or if anyone knows where I can find a new OEM. Any help is very appreciated. Let me know!

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.
