Can only work with what we've got.......

Umair , it was great to get your info, what I meant , if it had been the 6266 it would have made the 8374 low end response look even better , but I think the top end would be pretty close with both turbos

Umair,

I took the liberty of converting your results to excel and graphing them vs my pumpgas results (including corresponding boost curves). Looks like my combo of stock-bore 79mm stroker (2.75L) and/or the .92 IWG housing turbo is making a bit more bottom end than yours (below 4500 rpms), but obviously with higher boost and E85 you're crushing me anywhere over that. The boost is x10 for scaling purposes (ie 100 = 10 psi, 200 = 20 psi, etc). I'm willing to bet when converted to E85 and when I start pouring on the boost that I will make more power lower in the rpms, but not significantly so (maybe 250-300 rpms sooner), and with the increased backpressure of the .92 housing I'd bet I'll start dropping sooner as well.

Good looking dyno! :1311_thumbsup_tone2:

Not really surprised there though. Bigger engine making more grunt down low.

How long till you put it on E85, Harris? 

Station is targeting completion in november. I'm hoping to have fuel pumps, 3.5" exhaust, and mega huge injectors done by then. I'm still on stock fmic so we will see what it can flow!

will need 100m cooler. the stockies have been known to hold power back over 400kw.

3.5" will do the job. Mine is 3.5". 4" only if you know you are going to aim for even bigger power in the future.

My injectors are 2000cc. I was told that even 1600cc on e85 wont cut the mustard for 500kw. Makes it a little harder to fine tune but its not noticeable in day to day drive.

thanks for mapping the dynos. interesting stuff!

If anyone is interested, I'm maybe going to the SAU cruise to the Gosford car museum on Sunday.

Happy to take anyone for a spin so they can feel the setup for themselves.

if you need pricing on Plazmaman coolers @usmair give me a holla [emoji4]


What about me? Sounds like he's got a cooler.

I'm almost tapped on money these days (oilfield sucks here lately). I need a sponsor!

haha but you're in the US.. shipping won't be cheap.. however happy to help out - flick me a PM on which size cooler your after, and if polished/black/raw etc..

What range of mph would you expect to get from 500kw 

 

138-140mph??

I would hope! Thats a ton of power. I ran 120 mph on 464 whp and you've got way more midrange.

Borg Warner EFR Series Turbo's V 2.0

 

Link to the first attempt. A wealth of knowledge in it. 

annnnd go!

We gonna be factual on this or its gonna b like the last one >_<

What wasn't factual in there? 

You must have some EFR experience to share with us if you know there was nothing factual in there?

    • I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....
    • So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.
    • our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
    • What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.
    • Little update  I have shimmed the solenoid on the rack today following Keep it Reets video on YouTube. However my steering is still tight. I have this showing on Nisscan, my steering angle sensor was the closest to 0 degrees (I could get it to 0 degrees by small little tweaks, but the angle was way off centre? I can't figure this out for the life of me. I get no faults through Nisscan.
