143.7kW

Cisco, how much boost you were running at 143.7kW?
What is stopping you running more boost?

As you can see on the graph, it spiked at 20.7 in the mid range, sat on about 18psi for a while, but actually made peak power at only 16.5psi.

Also that was only 6500rpm.

I have also discovered that the exhaust idiot welded on a ridiculously tiny 2" exhaust tip. So I made that power through a 2" tip. That basically rules the whole rest of the 2.5" system useless because of the 2" restriction at the end.

So there is more power to be made yet even at the same boost levels.

First step is to get a brand new muffler (I think this one resonates badly that upsets the car), plus its only got 2" holes now. Get that fixed and in some cooler air, it will be guaranteed to push over 150kw at the wheels absolutely. Especially when my last dyno readout of 137kw was made up a lot closer to 8000rpm. The current setup feels a LOT faster.

I will get that exhaust fixed, colder air, more revs, and get back on the original dyno and aim to get some ridiculous printout like 150-160kw. I think that dyno is more generous on its readings too see.

Guessing you're just running a bleed valve on the wastegate line. In which case, spend a few hundred dollars & get a proper boost controller...

It essentially is a bleed valve. But its a two-stage adjustable high-low controller with electronic switch.

Yeah one day :)

Cisco,

Why don't you try water injection? I achieved VERY good results with my old turbocharged Micra.

Not only will it clean the combustion chambers, the steam generated will bump up the compression slightly, and you can also advance the ignition a bit.

With your setup, and the water injection engaging at around 15psi you'd be making over 150kw@wheels very easily and it wouldn't be hurting the engine any more than you are. And just think of how it will go during winter!

I can put you into contact with Jordan Ross, the Australian distributor of 'Coolingmist' and you can get a very decent setup for around $400 which you can install yourself, then get Ben to tune (he tuned my old setup)... I can help you install if you want as well, it wasn't overly difficult/long when I did mine..

Definately something to think about though, I'd love to see it on this car

Seano

Very good point Sean. Would work well on Monster.
I am sure Monster can crack 150kw. That would be utterly insane.

I'm certain it makes that already. 2" exhaust and revved to 6500rpm on a hot day! Easily maaaate :)

chuck it on a dyno dynamics on shootout mode prob make 160kw :)

thats dyno figures for you lol

Oh well lets say 160kws.
Whatever it ends up at is insane.

isnt it dynapack's that give overrated figures? it's a hub dyno yeah?

dyno dynamics dyno will usually read a lower and more realistic figure...

no idea...if its a hub dyno then yeah...could be interesting.

i know that i had a 10kw diff between a mainline and dyno dynamics

Hi Cisco , I am curious to know what the driving experience is like . From your graph it looks top endy , have you really got to rev it to get some boost or is it reasonably good down low ?

I should explain that I'm more used to larger engines and the boost starting lower down the rev range .

Cheers Adrian .

The dynopac is supposed to give the same read out as a rolling road.
I put my 2.0L turbo N14 GTi a dynopac in March and it pulled 348kw@ the front wheels on about 90% power. This was pretty much inline with the figures I had received when it was put on a rolling road about 6 weeks before.

Cisco do you use adj cam gears? I have to say the AVC-R we are using now is so much better than the Turbosmart dual stage we were using.

Holy Cow. 348fwkw! You have to be kidding. That is some pulsar mate. Congrats. I bet a lot of time and effort has gone into that.

I don't know why someone would make a dyno and calibrate it extremely differently just because it connects to your car in a different way. I can guarantee from the feel of the car compared to how it was with the old T25, that it is making a considerable chunk more top end power than it used to. And not just from the extra surge or rush making it feel like more. I am going to get this 2" exhaust tip replaced with a 2.5" and put it back on a dyno dynamics in this colder air to get a comparison readout. I am pretty confident it will read more on Jake's dyno that originally measured the old T25 setup at 137fwkw.

Re: drivability. Mate, the old T25 setup was certainly more drivable in terms of things like, exiting a roundabout in 2nd gear, the boost would more easily slap up to 15psi quite quickly and away you'd go. The boost threshold (what many people incorrectly call "lag") is definately higher (laggier) on this turbo. But its kind of like not that much worse compared to how much extra top end gain and durability this turbo gives it. Also pumping out colder air from not working as hard means safer power and more power earlier from colder air.

If you look at that boost vs rpm graph carefully, you will see that by 4000rpm, its already making 7.5psi. That is very similar psi that a lot of the other mild k11 turbos are running and making at the same rpm. So you could say it still feels fast at that RPM compared to a stock micra. There is certainly some decent torque surging feeling at that RPM. Its pulling harder than a normal micra and starting to pull away and feel some nice grunt.

In that next 1000rpm (providing you keep your foot to the floor), the power goes crazy. It more than doubles by 5000rpm. It goes from 50fwkw at 4000rpm to 111fwkw at 5000rpm. So as you could imagine, that 1000rpm is where its all happening. That is the spot where the wheels will start to spin and the afterburner comes on. In that sense, this part of the rev range feels like a typical old fashion non-linear turbo power band. Like whoooooooosh!!!

But remember, dyno graphs are always taken with the foot to the floor. As the car has already made 7.5psi at 4000rpm, I can give say only half throttle or 3/4 throttle to maintain that kind of boost or even a fraction more, say 10psi and the car still feels fast and strong, without the huge whoosh at the end. That would then feel similar to some of the more milder turbo'd k11s. The big power jump with the foot floored between 4000-5000rpm really is a bonus on top of already decent every-day boost and power levels.

If I leave it in the "low boost" setting, I can't find the graph right now, but I think it makes about 11psi or something like that. That doesn't come with the huge whoosh at the end, but you still get fairly level response. Look, below 4000rpm, there isn't a helluva lot happening. On the old T25 setup, I would say that same point would feel like about 3000-3500rpm. So its a bit "laggier" but really only talking about 500rpm I think for some really good advantages.

Considering that the action starts above 4000rpm, and the car revs all the way to almost 8000rpm, you are easily always in the power band after a gear change, so if you are really getting up it and going through the gears, you are always in the crazy power band area. So it can go really fast. That's why the quarter mile times would have improved a fair bit from before. With the old T25, after about 6000rpm or something, the car started to feel very linear again, like torque was dropping off and power was only gaining simply from the rpm increasing, not from any increases in torque.

I would prefer the current setup. To sum it up, it has pretty decent everyday response, but the stupendous afterburner is there for kicks when you need it

Are you talking about Bluey or the ride you just had in a FA 18 ??

Yes it is 348 fwkw =o) Have a look at the pic in my details.
And its road legal.
Good effort with the your Micra.

zoiks that is a weapon.

When bluey's afterburner comes on, the pulsar EVLGTI is only starting to come onto boost :) haha.

Well it used to come on boost earlier when it had the smaller turbo... when it did the 10.9 ..... & now we'll be waiting until after winter fro the strip to dry out.

Awesome. What was the smaller turbo?

Is this thing street registered?

Do you have any problems with anything snapping or wearing out quickly? I.e. gearbox or CV joints or anything? I am always paranoid about something snapping on my car, and its only putting out less than half the power of yours! But I'm sure you have custom gearsets and nismo LSD and that kind of caper?? Just like PULSSSAR from Perth over here used to run.. It never snapped anything after it had all that gear dropped in. Used to do mega burnouts :)

The smaller Turbo was a T3/4 that came off a Nismo Drag GTiR that was imported from Japan. We are now running a Garrett GT35R(GT35/40)AR 1.06

Yes it is street registered, although its not all that nice to drive on the road with that much power, tends to want to torque steer into the nearest immovable object if you touch the gas.

In 4 years we have broken to standard SR18DE RS5F32V gearboxes. Stripped 3rd gear.
The factory Nissan gearbox and driveshafts are very strong. We are still running Factory N14(SR18DE) CV's, Driveshafts,and gearbox. In the last 3 months we have fitted a Spool diff but up until that time it was still the factory Viscous diff. We have never broekn anything doing burnouts, and we use Hoosier 26*9.5*15" DOT drag tyres =o)
3rd gear was stripped when going down the track. I can post up a dyno print if you like?

Wow that's amazing. Very very impressive.

Yeah for sure, love to see your dyno readout.

fyi: james's/ghetto's n14 we all know and love for its huuuuuuuge smokey burnouts and bling bling engine bay is now plated INSSSANE.

Man that car is cool. Its definately my favourite N14. It is actually the car which got me interested in N14 SSS pulsars. :)
