I think went from 280 to 300, there is a dyno sheet before and after I believe.

Just reading through the thread now, going from 280 to 300 was just due to tomei poncams. Doesnt mention changing the turbo exhaust housing.

Although his first dyno is with the standard R34 GTT turbo and without touching the tune it made 219rwkw which I have never heard of before so maybe the dyno is a little happy compared with other ones we have seen.

My bad I thought you were asking about the poncams, I can tell you right now that dyno isn't happy.

My mate had his GT3076 rb30 with poncams tuned there on 18psi and it only made 260kw.

edit: same tuner as well pete puts a lot of it down to the neo.

Oh im very excited Jase lol :rofl:

just wondering how much different E85 & 300+kw will feel compared to 288kw on 98 :yes:

Considering the ping resistance E85 has got you could pump the timing in and see massive midrange gains. A 'little' extra assomometer numbers can be expect :thumbsup:

Also, its a GTX with E85....... Why stop at 300? Get a good tuner on board and tell them to PUSH IT. I would be surprised if a GTX3071 couldnt flow an outright max of 340 on E85

With all that extra midrange Id be expecting its going to be two different cars.

Well ive got the good tuner and i was shooting for 320+kw thought it seemed a modest figure to shoot for on moonshine dunno how my clutch will hold up with this kinda power though its only a modified standard by jim berry made 3100lb of clamp.

Might just get it PUSHED and see if you are on the money Jase but im definately expecting it to be a monster hahaha :banana:

May as well update this. Will post dyno sheet tomorrow

Car is now happyily running on united e85 and is an animal

On 13.x psi it made 276rwkw . Just makes power everywhere. Full boost in 4th is 3200ish

Sadly my 18.8 psi tial set up still hasn't arrived from the states but when it does I think ill just run 16 or so,there no real need for any more if I can't use it

So overall it made 40rwkw more on 1psi less boost just from e85

Thanks again to Martin and the boys at Willal racing. Tune is amazing

lol. i think ill put the 18.8 set up in and just see what it makes and how it drives. The car is a daily and is used for grip work so the tyres wont be the biggest fans

Haha im hoping for 320+kw with a big fat E85 midrange hopefully the feet can keep up with that kinda power because i will be at the limit of my setup after this stage or unless i build a motor didnt think id get this power hungry :whistling:

Im not 100% sure but think you want the 56t mate the 52t is more equivelant to the 3037.

Im sure somebody will correct me if im wrong lol :nyaanyaa:

thats correct. mind you with the .63 rear, 52t and e85 it really is pretty awesome. without e85, depending on the rear housing you go for 300rwkw is easily achieved

Be interesting to compare our setups once mine is on E85 next week as our setups are similar :thumbsup: when are you seeing full boost and what size are your injectors mate?

Ive got 850cc injectors a tomei pump and a GTX3071R internal gated

thats correct. mind you with the .63 rear, 52t and e85 it really is pretty awesome. without e85, depending on the rear housing you go for 300rwkw is easily achieved

HKS produced a turbo with the 52 trim comp however this does not mean that all turbos listed as 3037 aka 3076 are 52 trim.

      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?
