For the record, compressor RPM and pressure are not related... at all. 

Was looking for a loose estimation on how hard a 26 would spin it In relation to boost.

but yea thanks

R32, 6 boost high mount, 8374 IWG.

And the aircon used?

Genuinely curious, out of interest, for the sake of anyone who may wonder themselves in the future. Can't see the factory aircon line where they should be running under the compressor housing though, I think, but i think i see aircon lines wrapped in foil up at the firewall?

I believe so. Waiting on a call back from the owner of the car. 

Why don't you ring 6 boob and ask? Bugger making a manifold when you don't have to. FWIW, I've never heard of the issue you're talking about. R32/full race with the PS pump yeah, not AC with a 6 boost.

If that's the case that's good.
I had been onto Kyle via email and did ask him if there were fitment issues re aircon at which point I didn't receive a reply, however by that stage i'd got onto my mate about doing it, and he was competitive on price and willing to have a got at the low mount, so I didn't bother following up more on the 6boost. I was going to far to say it wont fit, i've read too much into the fact I didn't get a reply when I specifically asked about that. Either way the car is in the fab shed with a set of flanges and elbows so we'll see what comes out

I have 6 boost on 8374 iwg .92 efr with r32 AC on my car right now. I did make a new AC line because I had cut mine previously trying to get it to fit with the RAW brokerage manifold. The dampener in line would have been close to the bottom of the manifold for sure on the stock line. I cut the ends and just had my shop sweat 2' of line in-between the end fittings and covered with heat wrap. Works perfect

 

Warranty issues is why no heat wrap is present. Thought about doing it anyway but it seems to work well enough.

Zero hood clearance issues (that was the problem with the RAW). Remember the 9180 is the same size as the 8374...so there's room enough for a 1,000HP turbo on here.



Ran some more boost threshold tests: Temp = 91 F, 70% humidity.

1) Third gear from 2k rpms. Graph attached - NOTE that my closed loop boost control is starting to compensate at 3390 rpms (ie starting to give supply pressure to the wastegate).

  • 10 psi @ 3430 rpms
  • 14 psi @ 3712 rpms
  • 16.5 psi @ 3909 rpms

2) 5th gear from 2k rpms. Graph attached.

  • 10 psi @ 3059 rpms
  • 14 psi @ 3200 rpms
  • 16.5 psi @ 3278 rpms
  • 18.1 psi @ 3329 rpms

So this goes to show that the EFR will spool soon when loaded for long amounts of time, but that it still has a good bit of inertia with it to get it to respond on extreme low end. As stated previously with my setup, the gear greatly affects threshold. Granted, it's still hyper responsive and the low boost threshold in 5th is nice for passing on the highways because I'm still at those rpms while cruising so there is no need for downshifting.

Amazing spool :O

Its 2.75l? Stock head with cams? And on fuel pump?


BC 79mm stroker crank. Stock 86mm bores. Forged pistons stock compression. Squish pads mostly removed. Tomei poncam A's at 0 and 0 cam settings. 6 boost manifold divided T4 internal wastegate 8374 .92 housing hypertune V2 intake manifold and yes 93 octane fuel in the US

    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
