Hey guys got a problem my car didn't make the power I think it should have made.

Rb25det s1

Gt3076r .63 rear

High mount manifold

50mm wast gate with 14psi spring

800cc injectors

Bosh 044 fuel pump

Turbo smart fpr

Upgraded coil packs

Greddy copy intake.

3inch straight exhaust

Blitz dual solenoid boost controller

Microtech Lt12

I only made 296rwhp was the best run of the day at 18 psi

Seems low compared to others iv seen on this site?

Also I did notice that boost drops off from 18 nearly back to 14 at the top. Fuel and air sitting on about 11.6 . Any thoughts?

You will need a stiffer spring in the gate imo, and the .63 rear won't be helping things.

Can you get us some pics of your setup? Was the exhaust dropped on the dyno?

I didn't get the chart as I was not happy with the tune. Tuning was done at Godzilla motor sport. On his dynonamics awd dyno

and tell them to send you the tune file

I have a feeling the tune was shit house, also because it's a microtech lt12.. they're so clunky to tune with.. 2x tables to do essentially a single table can do.

I'll ask him to email it to me. Marks pretty good tuner. I mean it is a microguess lt12...

We had to pull some timing cuz she was pinging on boost. He said he thinks the .63 housing is to small

Not sure it's just a stainless manifold with gate mounted to it. The power I Made is not much better then a standard rb with a tune..

If you had bought a decent standalone and left the FFP, stainless manifold, fpr, boost controller etc off the list, you will have had more money to spend on finding the issue on the dyno.

    • 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.  
    • 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       
    • 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).
