Well my car just dynoed 212kw @ 18psi.

My mods include:

Microtech LT-8

Custom Frontmount

3.5 inch dump to cat 3 inch for the rest

Hyflow T3/4

h/d Clutch

Vl pusher pump as well as standard intank

Standard air box

Well i don't know what everyone else thinks but this seams a little low for the modifications. I though atleast 257kw because have beaten a certain silva with a rb20 before.

The dyno was not in shootout mode and had a ramp rate of 100

Did you dyno it with the bonnet down?

Thats the best way to get a more realistic figure. It is always a lower figure too.

I wouldn't worry about the figure if it was an improvement.

The real measurement is beating that 'certain silvia' and doing some quick times around your favorite circuit or drag strip.

Stop getting all hyped about the dyno figure.

It's a peice of paper, just like toilet paper its only fit to wipe your ass on if its not being used to help tune a car.

So what if the silvias got a better dyno readout. Scan yours into the computer and change it with photoshop to read 1000rwkw, then you can beat him at the races AND in a dyno paper stand off!

Yes you can say i'm a little focused on the dyno readout, I guess 212kw is not enough. The tune on the car was pretty S&*t, as soon as i gave it a boot full it detonated the loudest i have ever heard it. Sooo in 2 weeks it will be going back on the dyno, the same one as the rb silvia.

I'll let everyone know how it goes!

:D

Hi sik32, is this an RB20DET? No adjustable cam pulleys? No injector upgrade? No adjustable fuel pressure regulator? No internal mods? Standard camshafts? No pod?

If it's a roller dyno (not hub) 212 rwkw is 360 bhp, that's pretty good for an RB20DET with the mods you have listed. I'm surprised it didn't run out of injector capacity.

I sort of agree with the other guys, except I reckon the dyno might be a bit optimistic.

PS; let us know the dyno shop that the Silvia runs on, I want to take my car there and get a good bit of paper to wipe my butt on as well.

hey sik32,

I'm too am running a LT-8 on my recently purchased GTS-4.

Just wondering how you find the driveability of it in your RB20?

How's the economy if your just cruising along in 5th gear?

I don't think they have closed-loop cruise mode. So they don't use the oxy sensor, do they?

What about initial start-up?

I know the LT-8 doesn't use the idle stepper valve. (the thing on the end of the plenum) So do you have some sort of air by-pass valve to compensate for the greater amount of fuel at start-up?

I'm just asking cos I find that mine never starts cleanly especially after I haven't driven it for a day or so. Sometimes it even seems like it wants to stall itself cos of the lack of air (revs drop below 500)

As far as the economy on my car, it pretty bad considering that I hardly ever boost it around town. and I spend alot of time cruising in 5th gear. something like 350km to a tank:(

I haven't had a chance to dyno it yet but hopefully will in a few weeks.

anything you can enlighten me on?:P

ok Interloper, First of all I find Microtech a great computer if you are on a budget. Drivability is fine, as it drives like the standard computer, but there is a few things that dislike about my Microtech. Cold starts, the car sometimes stalls on the first turn of the key and will not idle properly until the car has warmed up properly. This seems to be a problem that most cars with microtech have.

Fuel ecomomy, well that went out the window along with my standard computer. Microtech is Very bad on fuel, this also may be caused by the tuning as I like it too be a little fat. Even when i'm off boost and on the highway it still sucks fuel like no tomorrow.

Yes approx 350km. If i could do it all over again i would chose apexi or motec because of money i have wasted on fuel i could have afforded either of these. No Joke

Good luck with it all:D

Ps thanks for the toilet jokes guys!!!!!!!:bahaha:

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.

      The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.

      Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.

      @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
