@Murray_Calavera done! 

I believe it would have taken a few more degrees but I chose boost > timing. Wasn't planning to run this much boost, but things didn't go to plan and I wanted to see 400kW+ LOL

Approximately where peak torque was:

Digging a bit deeper, looks like the IATs got pretty warm at 57 degrees, a new FMIC will get me that 430~440kW target!

That's disgusting. Some people think they can do anything on a public road. Probably in a school zone with mum's with prams. If I was a cop I would hunt down and throw the book at that total

Had a quick read back through the thread but got bombarded with coffee posts; what turbo and wastegate are you using again?

 

*EDIT* Found turbo, GTX3582, that still correct? What gate?

Close, a few things happened with Sparesbox and many heated phone calls later I ended up with the original turbo but with a free rear housing :)

  • Carrot GTX3576R Gen 2
  • Carrot T3 1.01 divided rear housing
  • Turbosmart Gen V 50mm
  • Sinco T3 twinscroll, single gate manifold (pulses split to the gate seat)
  • Tomei 260/9.15 Cams
  • 80lb Valve Springs & Ti Retainers by Performance Springs
  • Chyna Hybrid 76mm FMIC

Now for science put stock cams back in and report back, thanks

It took me 1.5 years to tune the car, if I put back stock cams then go and tune it again we would be all dead lol.

We both can hypothesise it could come on earlier however make less power.

Ahhh gotchya, sounds like Sparesbox is one to avoid haha. 

 

Actually a very similar setup to mine, bar the turbo. I've currently still just got the old gen (like 10 years old now, jesus) Hypergear G3, which is going to hold me back. Same cams, same wastegate, same springs and retainers, etc. What injectors and fuel pump/s do you have?

I'm running Bosch 1480cc at 3 bar (often called 1550cc, or 1650cc depending on who you talk to). At the back I have 2x Wallahbro 460s in an AI SPR400 tank, and a DW200 lift pump. Both 460s are PWM and DC is ramped as boost increases. No silly potato staging, to avoid spikes.

I did say 11.0 afr, but the actual trace from haltech is a lot closer than the dyno printout.

Alternatively - How confident are you that either is right? Why do they differ?

+5 for actually showing data though!

Awesome work Johnny, and thanks for sharing everything - science ftw.   Those IATs... yikes, there is some serious airdensity improvements to be had there.   Look forward to seeing how it goes with that lot sorted.

There's a slight difference as I run a cat converter in the car.. yes it has a cat :)

If a car runs a cat I never rely on the rear tailpipe sniffer for tuning, it's there as just a guide. I always insist running a wideband before the cat/cat area to get a proper representation of how the motor is behaving. Not to mention, if there are small exhaust leaks, that will introduce foreign air from a venturi.

Very streetable, you get about 1bar of boost by 4100rpm and the power is quite linear. If you look at the faint dotted lines when I took a photo of the dyno screen you can see that torque is relatively flat too.

As the car was going on the dyno, I borrowed a pair of old AD08R which were rock hard (didn't want to destroy my semis), on the way home was pretty funny. Roll into 3rd and the tyres would blaze LOL.

I'm heading to Wakefield this Sunday, should be a good shakedown!

good to hear your getting back out on track. Damn if track day was 2 days earlier I would stop in with the new car for a few laps.

Aren't you glad you kept it and kept going with your build? :D

Not really, now I have just wasted more money lol.. more money that could have been saved for a BMW lol

Scored a free track day, my mate paid for it since I tuned his car. Speaking of which, that S15 I tuned a while back with fuelling issues came back with a solid 274kW at 1.7bar boost on a GTX2860R Gen 2. It's making numbers of the older GTX2867R Gen 1 but at least 400~500rpm earlier.

Big power for a 2860! 

Good result for baby cams, no doubt e85 helped. How much timing? 

14 degrees mid range, sweeping up to 19 up top. Tried to pop in a few more, but wasn't worth it, as each degree only net an extra 1~2kWs.

      "Cheap" bolt on turbo on RB25DET NEO

      98 R34GTT 4k engine stumble

      By JC71 · Posted

      forgot to mention that when it does this it does not kill the engine, but I have not kept the pedal down long enough to let it, as I see no reason to beat up on it as its got to be something simple, small and dumb causing this.  And as soon as I let off pedal, the engine returns to its normal super smooth operation and rpms re-stabilize quickly, once below 4k.

      98 R34GTT 4k engine stumble

      By JC71 · Posted

      neither stumble or cut really seem to be an appropriate term....hard to explain its like a rev limiter but at 4k, but it violently shakes engine and entire vehicle as the rpms will not rise over 4k, even with slow acceleration. as soon as it hits 4k, it sounds like entire spark is lost entirely. plugs were 1.1 which I used as such, but later put in new plugs gapped down to .8 changed back after issue arose when I replaced the coils, still does it with either plug gap...damn and it was all running so good.

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      Oh how times have changed! I actually lean it out relative to my water/methanol injector duty cycle. The methanol adds a lot of fueling and you can then lean it out even more due to reduced knock.

      By Dose Pipe Sutututu · Posted

      Yeah my thoughts are the same, a well thought out WMI setup, would be slightly ahead of just straight E85 and you're also chemically intercooling the charged air, dropping it even further. This is why you need to add so much more fuel as soon as you spray. I remember someone taking me through their set up before (Dennis, has a R33, lives around Cabramatta - no idea if he's still around on this forum). He would target AFR 10:1 on 98, then as WMI ramped on, AFR would lean back up to 11:1. Amazingly, he did this all through his PowerFC, a relay to cut power to his EBC solenoid if there was not enough line pressure on his WMI kit. And of course, if there wasn't any boost made above gate pressure, you wouldn't be accessing the load cells with heaps of timing for WMI. One downside to that rudimentary setup, once the WMI came on, the EBC would unleash the dragon, and of course all the timing. Tyres would fry lol.
