Intresting, my mates stock r33 auto did 154rwkw on a roller dyno.. (Torque performance)

Another r32 gts-t, Rb25det, stock turbo, FMIC, Exhaust, Dumppipe, Stock injectors, Upgraded fuel pump. 211rwkw (14psi), Similar reults on shred motorsports duno and speedtechs..

Now with a g4, its at 230rwkwish, (less boost too)

FMIC is a fantastic upgrade and I highly recommend it, coils are around $3-400 for an aftermarket or stock set, the aftermarket ones are no better than stock from what ive read, just new obviously so they dont shit themselves.

if the tune has been sorted properly you should be able to get massive heat soak on a 35c day and not have it ping, if it does ping then the ignition coolant temp trim tables are not set up and nor are the knock maps, if you get it dyno tuned I recommend getting it really hot , run it with the fan off even and get the knock ears on it, it'll totally kill the power but it will tell if its pinging or not, if it is pull more timing or set up the trim tables correctly.

will save your motor if you thrash it on a hot day.

gapping the plugs down to 0.8 can fix misfiring if the coils are borderline, it is recommended to try this first, when you change them check the coils for arcing and discolouration from overheating, a tell tale sign they stuffed, also you can get 0.8 gapped out of the packet if you ask for the right plugs.

What is heat soak exactly?

Thanks stagefummer11, I thought i wasn't crazy. I definately think I should be getting 170ish with my current mods, more than 150 neway.

Rolls, I seriously do not want to go down the tuning line again at the moment. If I did, I would have to go with someone else or do a full dyno $tune$. My tuner seemed to think that it was fine and I can only trust him that he knows what he is doing because I don't. I am sure you know what your talking about but I 'm stuck in the middle wondering who to listen to?

I would rather get a fmic as I think it would be cheaper than doing another tune+dyno runs (Still retaining the smic).

When it pinged, apparently it was doing it slightly and not badly. It had loads of fuel going in so the pistons wouldn't melt at least :D

I'll take your advice and look to adjust those gaps and then maybe if the problem still exists change the coils.

Could it be that the gapping of the plugs and/or shotty coils are the problem for a lower power estimation?

ignore the 150, ITS A GUESS, a very rough one at that. no number on his computer could give him an exact power figure. and ignore the dyno sheet above, 240rwkw from a stock turbo isnt all that realistic, and whilst it does occasionally happen its nothing to get hung up on.

fix your plugs/coilpacks and do a $50 power run on a dyno anywhere just to put your mind at rest....

and heatsoak is when your intercooler (in this case, can be anything) gets heated up from the hot shit in the engine bay whilst sitting in traffic or not moving much for whatever reason. the cooler sucks up all this heat and does a lowsy job of cooling the intake air going through it until you get some speed back up and get some cool air flowing through it again.

Heat soak is where everything in the engine bay (intercooler included) gets soaked with heat, basically means the intake air is much hotter than it should be and everything is just generally very hot, this will be the conditions that causing pinging if it is going to ping, it is the best way to test your tune is safe.

If he gave the car back to you with a tune that was pinging even slightly then he hasn't done his job, even small amounts of detonation are bad and will cause damage over time, not to mention the hotter the weather and the worse the fuel the more it will ping.

It is very hard to know who to trust when it comes to tuners, basically I won't go with anyone unless I can sit in the car during the process and see what they are doing, anything less just won't leave me with confidence.

I did sit in the car and drove it around while he was watching what was happening on the laptop. He told me that everything was good and no pinging at all... What more am I suppose to do? He claims to have tuned multiple skylines to 300rwkw or there abouts and out of many, only one has given up the ghost and he said that engine was sick anyway.

I adjusted the plugs today and it is still hesitating. It would hesitate at 3000-3500rpm and then perk up and then lag again. But not necessarily all the time.

The plugs looked pretty good, maybe a little yellow. No sign of detonating. The coils looked yellow through the plastic cover. Not sure how to tell whether they are worn or not. Do I take the plastic cover off?

Air filter came today :) will install tomorrow.

"When it pinged, apparently it was doing it slightly and not badly. It had loads of fuel going in so the pistons wouldn't melt at leas"

I thought you were implying it was still pinging, my bad.

It was pinging on the dyno run (my tuner wasn't there). So he test drove it to see what was wrong and why it would be pinging and he said it was fine when we road tested it.

Just put in the air filter today and noticed it to be quite perky and fun especially considering it is a hot sunny day and my wife had the A/C on. It will stay in 4th gear a lot longer than it did before. I have to almost floor it to get it into 3rd. LOL, I'm guessing cause she doesn't need to change down to get acceleration :b It is still only running 10ish psi so I will give it a bit more of a tweak.

The car seems to hesitate a little still, but seems better since changing the plugs and the air filter. I might put up with the coils till they die a little more.

Who knows what power it is doing, definitely faster than stock though :D

cheers,

Dan

rest at ease if your running a little more boost and have atrimmed up tune you will be making a little more power. As you are now aware more power was never in doubt, just the exact figures and level of safety.

i beleive one way of testing the coils was to unscrew one and lift it from the valley slowly while turning it over. the measurement is basically how far the spark can jump before it no longer fires...

That said i dont know the exact procedure, hopefully someone here can clarify, and i'm not sure what an acceptable distance is.

Hopefully doing this test will let you guage just how arsed up you coils might be and will let you know if you need new ones now or later if at all.

As for fmic's, put one into your upgrade plan and dont plan on relying on the smic long term, even with water squirters etc etc. things like the later require you to constantly maintain fluids for operation and water cooling is primarily effective when a vehicle is moving.. it doesnt as much when stationary. a larger cooling surface area will always do a better job long term. so throw a water squirter together on the cheap short term... but dont rely on it long term.

all in all though it sounds like things are coming together. i think the only advice that really needs to be given is to modify your car with an aim ton enhance longevity, if you do this as your primary goal then normally small but noticeable power increases come with it without chasing big figures.

Just got back from a 3 day trip down south... Fun road trip, and I even was on the tail of a fast looking year 2000 + audi up the brynderwyns ; )

  • 2 months later...

get it back on a dyno mate. you told us before you had it on the dyno and it was pinging (but for some reason you don't have a power figure from that?). then you took it to a mate who drove it on the road with his lap top hooked up and told you it's not pinging. completely different conditions. of course on a fang around the street it may not ping but loaded up on the dyno (as it will be in 4th and 5th gear) it pings. having 1 big fan in front of the car is normal for most dyno operators. get it back on the dyno and find out if the tune really is ok or not. it will also give you the magic power figure you want. the tuners guess of 150kw is just as random as the bloke who sent you the mail order tune saying 190kw and I could guess and say 160kw and it has just as much relevance as those guesses do as that is all they are. guesses. use a dyno. it's a tool used to measure power at the wheels. that is what it does (well that and simulate road driving so that cars can be tested and tuned safely and conveniently).

edit: just read your post. well done. now you have a figure and now hopefully any pinging (if it was pinging) has been tuned out. enjoy. :)

cheers,

It is pinging a little but the knock sensor is kicking in to prevent it. Currently we are talking about this in another thread, my flat spot thread... I just wanted to tie off loose ends here for anyone reading, that is why I commented here about my power output. The guy that tuned it on the dyno (recently) is the guy that did the mail order and the road test initially (He didn't do the dyno run where it first pinged).

His dyno he used was the "velocity" one in Auckland which had a proper cooling room (unlike the first one) that literally sucked air through the room from huge fans at the back as well as fans on the front of the car... mean :)

    • Keen to see the turbosmart data, to date I've only seen negative things in terms of response for them. Very small sample size though.     Hawkins is a big advocate in his videos of the larger rear housings. I managed to make similar power with a lower spec motor on the smaller .8 rear, keeping decentish spool.  The people he works with now are big power cars compared to mine though, mine really is setup to drive around and enjoy.  I don't have any back pressure monitoring though, so couldn't say if its good or bad on my car, just that it does what I want it to do.   Future I want a higher compression more cubes motor to give a bit more bottom end and hopefully the new g35-1150 gets me to the 850 rear comfortably.  But maybe I won't due to exhaust back pressure.
    • No, I refuse to buy their cheap ass crap! I do need to order a bunch of different nuts/bolts to refill my nut/bolt wall though. Maybe you could go for a walk through Bunnings for me? (Or send me some stuff from your work? )   I really struggle to work out how the US standardised to Metric in what the 70s or 80s, and yet, half a century later, there's been little done to actually bring it into fruition. It truly baffles me    On the whole Fastenal thing, I went reading their site (My god they sell a lot of varied stuff!), and it seems like it really depends what store you're near if you can walk in and just grab a few small things, or if that branch is primarily distribution with only a small window of "counter time" available (if at all). That definitely makes it harder, as move locations and it drastically changes your ability for success   For things like your M6x1.0, if you want to work on your own Skyline, and you also have a "home workshop" I'd recommend setting yourself up a small Nut/Bolt wall/section. It doesn't even need to be big at all. Most things depending on the diameter, will be a specific pitch, like the M6x1, M5x0.7 etc. Bigger bolts is mostly 1.5, except for a small number of things and that will come down to torque. From memory bolts for the brake calipers (and other things that need a lot of torque) will end up being a 1.25mm pitch. Save up a few dollars, and order a range of nuts/bolts. If you want to minimise cost a little, buy something like M6 x 40, and M6x70mm (1mm pitch) in both. In addition, buy yourself an M6x1mm thread chaser. That way you have long bolts that you can cut down to size, and then chase the threads out. Funnily enough, I find what I'd pay here for ordering 5 bolts, I can pay about 50% more and you'll get 100 of them.   If that doesn't quite work out due to space / ability to buy plenty up front, then each time you need some bolts, order 100 of what ever you're getting. Put them in clearly marked containers. Over a few years, you'll acquire plenty of different sizes, and will end up ordering less and less. And the cost for 100 bolts won't be much more than you paid for your 5 you needed to order anyway  Just takes a little planning ahead, by investigating what nuts/bolts you'll need, and ordering them before doing the job.     Edit: If it's also primarily for working on just the Skyline, for some reason my brain is screaming that at some point, either Nissan, Nismo, (Or possibly a third party) was selling a "kit" of every nut and bolt in a Skyline, purely for people restoring/rebuilding. It'd likely be quite expensive, but would give you every/any nut/bolt you need for stock/factory things. I'm not sure if it's still available, or even if it actually fully came to market, it's just something niggling in the back of my brain that you could look into further if that sort of thing interested you? (It might have been for the R32 GTR or something specifically too, and not just any Skyline)
    • 90lb/min @ 20psi is wonderful, not so much of a problem with the G35-1050's compressor efficiency (aside from how bad they roll back at higher pressure ratios).  The issue is more to do with the turbine's flow, which is why I'm not sold on going an even higher flowing compressor with the same turbine.  I'd say go back over Motive DVD's testing of the G35 1050 and Hawkins's comments regarding exhaust back pressure issues with it, I'd need to go back but I have in my head he went to the biggest hotside and ended up sacrificing a lot of spool (so it ended up behaving like a bigger turbo) and still had EMAP issues.  I've heard various other experiences along the lines of that. At this stage at least I rate all I've seen about Xonas (for transparency I've not used one directly, but I have spoke plenty with people who have) to have low exhaust restriction for the response they offer for any given setup - basically they allow the engine to breathe, which is good for the engine and makes making power a lot easier.  You arguably don't have to even push quite the same amount of airflow through an engine to make the same power if you don't have the bum plugged up with exhaust gas struggling to escape the engine due to an underflowing turbine.   In terms of reliability, to be fair I've had great luck with Garrett turbos as well - my GT3076R lasted forever, then I sold it and the next owner had no issues, then that car got sold and it was still going strong last I ever heard about it.  The trick is with the old GT-series turbos the compressors etc were no way near as efficient as what we have these days, it was almost hard to push them into severe overspeed situations without having a boost leak or something - and that is what often starts the failure situation.    In terms of your G35 I'm pretty sure you're running yours within sensible limits, something people with Xonas and Precision turbos aren't often so inclined to do.  The "compressor maps" are "Joe blogs ran 45psi through his 6466 so I can do the same" and built their setup to send it to the moon.  I've seen EMAP and compressor speed data where people have actually set that stuff up on Precisions and Xonas which have been run hard and the comp speed numbers are very very exciting at times - like I've seen 76mm Precisions run at rpm that you ideally shouldn't run a G35 1050 lol.   I know people who have run G-series Garretts hard and hard a failure, then replaced them with Pulsar turbos as a cheap "get it going" stop gap with the intent of doing a proper upgrade when THAT fails... and are still running the same thing.   Like anything, ymmv and it's not always to do with the quality or trustworthiness of said product. I've been provided with a bunch of compressor maps for Turbosmart turbos and will update my list based off that, they could prove to interesting reading and an interesting alternative as well.
    • Just cage it, call it a race car, and then fall in love with the chirp chirps through pit area!   Also, this is coming from someone with a completely locked diff...
    • I still have an old R32R left over from when they were a thing in the early 2000's. It was, for its time, done about right. But its time was 20 years ago.  I did try and update it a while back but it was cruelled by a (recommended) muppet of a tuna who couldnt tell his MAP from his TPS. The original spec was: Power FC, 700cc Sards, Nismo pump, 2860-5's, cams (Basically Poncam A's), Z32 AFM's and a half sorted oiling system. Thereabouts 430rwhp irrespective of what was done. So, yeah, very 1990's. I eventually got sick of it not being very refined and bought a Link G4 PNP with some 1000cc Bosch injectors. This was tuned badly and I put the car in the shed for a few years whilst I sulked and went and did other things. Ive come around to the idea of getting it going again so it has a new gearbox installed and some other minor things in the planning. So my questions are, variously (In the context of keeping the Link) What other sensors should I be running eg It has no wideband on it at the moment, nor fuel pressure. $? Is it worth chucking the old ignition system (ignitors etc) for new ignition coils? $2k? Cam/crank angle sensors? Can keep the aircon? $? Anything else? Sorry to launch another what should I do with my car thread but, you know, what should I do with my car? Random photo for historical context.
