Note to all. Finally moved my cam gears on the dyno. Spent 4 hours there yesterday (on a dynocomm inertial - which will soon be eddy brake). I now see what a V-cam would do for you. Moving my Pon

Just came back from my first test drive and it's hard to compare the two. It's absolutely ridiculous now. Dyno graphs will only tell half the story in this case.

Excellent!

How does just normal driving compare between the two?  And how much harder is it to get it to stand up initially?

Believe it or not it's actually much better. Precision did come on early and was responsive, full boost was a lil earlier than the efr but had that either on or off feeling during normal cruising, didn't have as much middle ground. If I'm making sense. This one is very progressive and smoother to drive around, always has something down low, you wouldn't think it's even a modded Gtr it's that smooth. This was very unexpected! I change gears and it just picks up right where you left it just continues. It's hard to explain but it's very impressive!! I'll get a vid up of cruising around

I had a PTE6262. Just ran out of puff at 430ish, I thought going anything bigger I'd lose the midrange punch which was awesome but yeah now it's even better.

Yeah would be interesting to see how a 9174 would go.

I was waiting on a 9174 for 5 weeks as they had a shortage of some stock or something and just cbf waiting. Chris thought 9180 would be a lot laggier when I dropped it off but yeah good outcome.

And yes you got my Precision specs right lol. You've seen more of it than me [emoji23]

Starting to think I may have been a bit too conservative on a 2.8 Neo with VCT and a 7670 Buraz's result would be bonkers with AWD and 8k rpm to play with!

"Whatever size you think you need, go one up".

Seems to be quite fitting.

8374/1.05 on that thing all day!

That will really be put to the test when my car is running. All well and good to use a fancy turbo on a fancy engine, let's see how they good they work on an absolute nugget engine RB20.

Note: I don't think that 25/26 are really that fancy, just much better than 20's haha

So, just a small update:

I am flying out to pick up the car tomorrow. I will post some more pics when I get to the shop. Preliminary results on 91 octane are 558awhp. I didn't get the e85 numbers yet, but will tomorrow. Will post dynographs and give an update on the driveability of the vehicle as well.

What kind of dyno is this on?   Good luck for the rest of the tune, keen to hear how it goes - if you are winding it up then this should be a drop in the bucket considering what twin 6758s should be capable of :)

It's a Mustang AWD-MD-1100 dynamometer. I don't entirely know what this means though (in terms of output comparatively to other dynos). And yes, I am hoping for quite a good amount of power so, fingers crossed!

Cheers for the updates - that is actually even laggier than I expected, but of the ilk.  Glad you are at least not having issues building higher boost levels.... is the higher boost/E85 tune still being done today?

641+whp on 91 on a Mustang dyno isn't kidding around, that will be very interesting with E85 in it :O

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
