Just thought I'd share:

R33GTST

Mods:

10 psi

3" dump (batmbl)

3" CAT (batmbl)

3.5" Cat back kakimoto

Pipercross Panel High flow filter in stock box

R34 intercooler

PowerFC

Results:

BASE MAP: At 10psi gave around 145rwkw - see graph - AFR very rich and some aggressive timing in the wrong spots.

TUNED MAP: Around 172rwkw. I think final run was 170.9rwkw as some timing was taken out. On the dyno knock was kept below 20.

ON THE ROAD: Feels more repsonsive, but most gain is when you get over 3500rpm - 4000rpm. Going round corners the tacho flies towards redline as the expensive michelins battle for grip where they didn't before. Only thing is knock went to 58 on the way home. I might call the tuner in the morning..he seems to know his stuff though. I'll have to see when the knock is occuring. Hard to see on the hand controller..might have to get someone else todrive and have a look at the bar chart..

I should ad that the dyno is apparently quite conservative. Cars often make 5-10 kw at the wheels more on other dynos for some reason.

The tuners thought this was a good power level at this boost level with a fairly stock setup. I didn't ask for max power just a reliable tune. With light/medium loads tuned aswell.

Nice power - yeah we both might have to talk to our tuners.

................. Before....................After............. Gain

3000rpm 100rwkw ............100rwkw

4000rpm 114rwkw ............116rwkw ..... 2kw

4500rpm 125rwkw ............134rwkw ..... 9kw

5000rpm 138rwkw ............153rwkw ...... 15kw

5500rpm 144rwkw ............164rwkw ..... 20kw

6000rpm 148rwkw ............170rwkw ..... 22kw

6500rpm 148rwkw ............172rwkw ..... 24kw

Not sure if the before and after are correct for the low rpm as he did some tuning at lower rpm before he did the power runs.

Skyl9,

Compare average power of the safc to pfc. Peak power is not the be all and end all. THen there's the factor of dyno's provide different read outs, some lower some higher. :P

+ Its only 10psi, push 11-12psi and it will be definitely noticable. :)

I have pretty much the same mods as you.

Do you have electronic boost controller? I use the PFC one.

I made 207 rwkw (hub dyno) at 0.7 bar (10 psi).

Was the hand controller used to tune? Mine was tuned using the Official Apexi Laptop software.

The FC Datalogit was used to tune it. No electronic boost controller. Just a simple bleed setup.

The tuner is the one Sydneykid recommends - he tunes 400kw hondas and many skylines. Compared to others he thought this is a good figure.

Not sure how a hub dyno reads compared to others.

On other dynos this could be 180-190rwkw. When you think it is only 10psi I am pretty happy. What do LS1s or Xr6T stock put out at the wheeels?

FFS Why do people keep comparing results of one car on one dyno with results of antoehr car on another dyno!?

You should all know by now that a dyno is a tuning tool - you can calibrate it to read onehundredmillionbaziawatts if you want to...

it's RELATIVE INCREASE that is important not the absolute number

benl1981 - good result and increase from tuning.

Thanks Ronin. Yeah I think people get carried away with "an R33 can make 200rwkw with these mods etc".

I didn't say to the tuner "others have made 200 etc" I was happy with the gain that he achieved. On the road the acceleration is much better.

I know Im not going to win dyno comps and I dont really care too much about the end power figure. This tells me the car is relatively healthy and running to its potential giving the mods I have.

Thanks R31nismoid. Yeah I'm not in ahurry to pull the turbo off it. The way I see it the next power increment is a little bit more expensive.

To go further than this safely:

Possibly new AFM $300

FMIC $600

new Turbo $2000

fuel pump $200

+other things

+time

+it won't look stock

About $3000 or more.

I know the car has a lot more potential but I'm pretty happy with it.

Probably similar in acceleration to a 250kw LS1 or XR6 turbs but I'm not really sure - maybe they would eat me I dont know. My smaller 6 makes the power up higher.

Skylines are a bit lighter - my car about 1400kg vs about 1700kg.

Quite an adrenalin rush now.

Sure I could push it and get another 15rwkw but how long does the turbo last?

Edited by benl1981

Yeah EBC should be your next step... then you can bump it up to 1 bar next time an XR6 with a front mount pulls up next to you B)

Plus the advantage of boost much earlier in the rev range.

I have a bleed valve on it at the moment, one of the $30 ones on the forums.

I might swap it for an orifice piece that goes in place of the standard solenoid. Then it looks more stock.. just thought Id get the tune on the bleed valve since it may bring boost on a little earlier..atleast then the load points are tuned

These cars seem to hold boost pretty well.,

Yeh ive been reading up those $30 boost controllers are pretty good. Supposedly there not even bleed valves. Id stick with what you have if your happy. Im going to go down your line of mods but i'll be doing a fmic when boost is upped.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
