Car is finally booked into Insight on the 19th of April for the ECU, fuel system and sensor wire in plus the tune. Thats the good news. The bad news is that V-cam aint gonna fit with my pistons and ho

Small update.... ITS RUNNING. Fired first go! Smells like burnt dust apparently .

A 9174 would just make the EGP pressure issue worse and in my mind it seems like a bit of a GT RS shit going on. Not that it's horrendously bad (It wouldn't be no twin buttplug pressures), That's NOT

Area under the curve is more important than top end power IMO, your car will be mental. That's why i designed my car the way i did. 

Even at my relative power level i find for street work, it's getting to the point the extra power is useless. 

I'm loving my current tune on 98, i can't wait to see it on E85 again.

I believe Scott is spending all day on it today. No idea where it's all upto apart from the information I've posted.

Cant see it making anymore than 480 awkw. That's as much as Scott has seen out of a 8374.

how hard are you planning on pushing it - boost wise?

Whatever 125,000 Rpm is. It will be higher early on then taper off as the engine consumes more air. 

So. Bring on 125 k ASAP and leave it there. Boost, who cares but at guesstimate, 30 ish psi as it comes on (late 3000's/4000 ish) and mid 20's at 8000 rpm. With any luck, hopefully less "boost".

interesting. looking forward to it.

Just for fun rather than anything else - i compared my power in the midrange compared to yours - i'm at ~100kw at 3700 - you've got ~270kw - same turbo lol

I need me a stroker kit

Update time!!!!

Fuel is E56 only

Still not bringing it on as hard as possible, just letting it come up as normal (not tuning via turbine speed YET). 

Turbo is a EFR 8374/1.05 AR turbine housing.

300 KW at 4000 ish, 461.5 KW at 6000 RPM then it falls over. I didn't see this coming but the issue is the turbine housing is too small! The next size up is a 1.45 AR which is the same housings they used on the indy cars. They were saying that the head is  just breathing like a weapon. Funnily enough, both Petes and Intune's car were able to stretch to 8000 RPM even though their engines are larger!

For the time being I will take it back and enjoy it for a while. If I put the 1.45 on, Scott thinks it will see 500 KW and make even more through the middle by 20-30 KW. However, i'll lose a tad at 3000 ish RPM.

I suppose I better get used to short shifting. Lucky I have 6 gears. 

For those of you who are hooked up on boost numbers, 25 psi at 3850 ish RPM but that will improve again. Pretty sporty for a lazy, laggy single turbo :1_grinning:

Go put a 6258 on your car.

I built mine so I could have a strong top end . I want to keep it and as tried to get it as good as I could down low . 

I don't want to loose anything from the top end, I still can rev it to 8000 if I want .  Just like it a bit different than most I guess :/ 

That head you had done is something else , cannot wait to see it all working together, what a machine :wub:

I just found a pic of you image.jpeg.b25b27a9dbf556a841d944083f03f787.jpeg

Congrats Paul, now enjoy it for awhile and mull on can of worms thats just been opened but was hiding there in front of you.

What brake set up are you running ? Reason I ask you may find that other things may need upgrade first, like stopping ,fine tune the nadling (think you sorted that but f**k me too much alcohol brain damage cant remember shit) then sort last power upgrade, all just subtle stuff. Then you'll have the ultimate skyline weapon.

Brakes are sorted, mate. 365 mm 6 pot fronts/350 mm 4 pot rear alcons. Need to change the front pads, the ones in there are woody nuggets!

Suspension and arms are all sorted, although it needs a wheel alignment. The whole rear end has been out to replace the sub frame bushes.

Cant believe I'm out of rear housing. Quite strange that the 3.2 and 3.0 can go to 8000 rpm but the little 2.8 cant. I suppose those polished ports ain't so bad after all ;).

I have in my head the 1.45 isn't a straight bolt on. The housing absolutely MASSIVE!!!! Adrian (bloke from Insight) said if they made a 1.6 you'd put it on haha.

Data is showing 46 Psi in the exhaust manifold. 

Im heading out tomorrow to sit down with Scott. Grab as much data as I can.

      Theoretical Power Numbers

      @Butters I can't tell you why but the bigger HKS step 2 cams improved low and mid end immensely. Turbos started spooling about 1k RPM less than before and the idle/vacuum was rock solid, it was an absolute thrill to drive, 3rd gear pulls hit 180kmh where previously only managed 160. Conversely, the milder poncoms in there now have a funky idle making it harder to get off the line, drives poorly in lower revs, laggy and makes less power/torque throughout. Feels better after I swapped the EBC but unless I put it on the Dyno again, I can't say how much better.

      Cams are not needed at this power level, they will create lag. The cam gears are a good idea though.

      @Murray_Calavera yeah, I guessed as much, cooler temps, more boost, less knock, more timing, hello power. Unfortunately not quite within reach ATM, could upgrade my whole fuel system to support but still wouldn't have E85 to run it 😂  Anyway, I changed cams again, 260/260 poncam B and everything else the same except an EBC upgrade. Now I must say I was quite disappointed with the result as it was like running stock cams (didn't try to dial them in as they're supposed to be optimum already) but after awhile I suspected my new EBC was underperforming not to mention difficult to use. I recently swapped back my old EBC and it drives much better now, boost comes on sooner, more stable, no spikes etc, feels all quicker and faster than with stock cams. Planning to fiddle with the cam gears and see what happens but maybe skip the Dyno as I intend to revert to the HKS cams cos they really made the car come alive; low and mid end was unbelievable and it just wanted to rev to the moon, finally knew what people were raving about, RB26 really loves revs. Anyway, Dyno 03 is quite disappointing, in Dyno 02 although peak power was less and trailed off at the top, the low and mid end improvement more than made up for it.

      @Darrel It's so tempting to say e85 is borderline magic. It cools the intake charge, so if you're flirting with the edge of the turbos compressor map it helps dramatically cool down the hot air the turbos are pumping. It is very resistant to detonation so you can crank the timing, I don't really want to say you won't be knock limited anymore.... but you probably wont be knock limited anymore lol. I wouldn't be surprised if you made 20% more power swapping to e85 (provided you have the fuel system to support them, bigger injectors maybe bigger pump etc).
