Hi all!   I've not really been active on this forum for some time and although I lurk in to read bits and pieces of interest I don't really think of this as a forum I'm part of but I once was and I di

Haha - yeah it could use some more boost Simon..  I'm sorry I've not put up Motec logs in the past for those who've wanted to see. Back at the time I did a bit of comparing because I did more or

mr skidz, your posts are coming off as trolling at this point.  do EFR people go into precision threads and talk about how great their mates setup is, but wont give any details??  whilst complaining t

nice info from the tuner. it really does look like a gun set-up.

Yeah good to see someone giving some extra information!

The power at 4000rpm is very impressive :)

I'm assuming the "old set up" is a stock 2.0L motor with a GT30ish sized turbo

The tuner posts some very nice and detailed info, that's great.

And wow, better power AND response than previous setup, agreed with SimonR32, looks like it was GT30-based. Win-win.

And it loses nothing to factory 4B11.

i want one now.

Even at 18psi it's an animal to make so much power as early as it does.

I wonder how an rb25 would go trying to spool it....

I would expect peak torque to be a little higher in the rev range but the transient area to be a little better to compensate (think linear inline 6 effect).

Now I want to see a 7064 on an SR, might just have to get one LOL

yeah I wonder how a 7670 would run at 30psi on my Jun RB27? but given how responsive the 9180 was on berrys RB30 I was thinking 8374 for me but if the 7670 can make the power I want (380-400kw atw) then why not use it? I'm still not convinced it's a genuine 600hp/400kw @ 30psi at the treads turbo though but if it is then it's bloody awesome.

Beer Baron - Depends on the dyno you're reading at the treads at, some rolling roads (ie, Dynojets) often read the same if not higher than Dynapacks... depending on the setups of course. This is ~470kw @ hubs, I'd say if this is a genuine reading, then I'd think 380-400kw on a DD should be realistic.

I can't believe how boost thirsty these things are....Hope my engines up to the task :wacko:

Its the EVO that needs that boost to make that power, though I'd still have gone the 9180 for an RB30 personally :thumbsup:

My "410kw" on the same hub dyno with the same correction (SAE) went 360rwkw on a Dyno Dynamics roller...

So I would imagine the 30psi E85 run would be around the 400-420rwkw

Its the width of the compressor map that inspires me to say that more than the outright power numbers - will be interesting to see what kind of power the EFR8374 lets through when not pumping 2+bar through it.

Thanks, but I'm well aware that you've previously posted those results, not really any need for name calling, most of us are adults here.

Maybe on the dynos you use there is a 70kw difference.

I didn't call you a name?

The dynos I "use" is the same dyno with the same correction as the result of the Borg Warner EFR on the last page (so a viable comparison)... It's also the same dyno that STATUS (not from Perth) uses. (battery, with almost an identical set up to mine makes almost exactly the same power as mine on the STATUS dyno as mine does on the Allstar dyno)

It's also worth noting that we know the hub dyno reads higher than a roller, which is why we usually leave correction off. With correction turned off it's still 30kw difference between the hubber and the roller! The 2 runs were also on the same tank of fuel with about 50km of driving between the 2 dynos...

Also in regards to the shot at high reading dynos in Perth, good one... Original, pitty the mph does not lie!

Now you just sound incredibly ignorant.

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
