ER34 (Skyline GTT) with RB25DET NEO engine and Garrett GT3071R. Running with 480CC Nismo injectors, Z32 MAF making 275rwkw up from previous stock turbo originally with 219rwkw

S14 with RB25DET + RB20DET loom and ECU. Turbo was a Garrett GT3076R with 0.63 rear housing. It was running Z32 AFM with 550cc injectors. It made 308rwkw.

Nistune R32 board tuned by The SpeedLab
This was a workshop experimental project to see how much power could be made with a standard rb20det. Personally i was surprised that the standard pistons could handle more than 500hp. Somehow the engine is still running and shows no signs of blow-by or failure. However it was only ever run on the dyno at a fast ramp rate. I am sure if it was loaded up hard on the road it would fail eventually.
Some special cam timing and other little tricks were used... No problems controlling this with a standard ecu. Is there a more powerful standard internal rb20 out there?

This was tuned a year ago. About 2 weeks ago the same car was run again and made 315rwkw on 23psi. Reliable and consistent tune with Nistune.

The car did end up making 286rwkw @ 20psi on a 100% internally stock RB30 high comp motor. - although it tried to squeeze the gasket out the side of the block the next day! (no detonation marks on the flame rings, just stretched!) - but not until it ran a 12.3 and a highest of 116mph. Only managed to save the dyno sheet for 274rwkw @ 20psi, but thought it might be worth chucking it up on the results page
The full specs and details of the hi-comp boost experiment are on the CalaisTurbo Forum
but in brief, 100% stock 250,000km rb30 motor. only two maintenance items i'd done were ACL monotorque head gasket (aftermarket stock replacement) and some fresh valve springs i had lying around. - moreso preventative maintenance really! - Standard N/A cam, no head work at all etc. Motor was a little down on comp accross all cylinders, just a little tired I think. Z32 AFM and 750cc siemens 3145 injectors.
Anyway - The turbo is a GT3582R with .82 rear. I have a "4800"-ish stall converter (intended for the built motor I'm putting in now) - it seems that by the time my foot touches the floor, it's at full boost! View Video On YouTube
Not only did the car pull a good peak power number on the dyno, Trent @ status tuning (I highly recommend them) did a remarkable job at making the car drive smoothly and happily! - no grumpiness, and he managed to smooth out any reversion issues with a few magic tricks! - after it was tuned professionally, I would have been happy to throw the keys to my girlfriend (in the dry) - which is testament to the tune-ability of the system!

Just a bit of feedback on my NIStune-powered 200SX S13. Had NIStune installed for 2 days (no issues whatsoever), and managed 382.8bhp & 326.2lbft @ the hubs on a DynaPack dynamometer. The run was cut short due to mechanical sympathy. Quick spec: 1030kg, standard 1.8 CA18DET (2 x standard headgasket + over-torqued head), T70 (Garrett T61) @ 1.7 bar, 510cc injectors @ 2.8bar. No knock at all. The AFRs are lean off-boost due to a leaking V-Band. Just like to say a big 'Thank You' to Matt for designing such a wonderful management option. This could well be the highest power from a non-forged CA, trying to find out what else is out there. Having a lot of fun exploring how far I can push the standard engine. With a new (fully forged) build on the way, I'm going to stick with NIStune (obviously) and standard ECU with a twin-MAF set-up.

Well had my first car with a map near completion dyno'ed today. Its a RNN14 Pulsar GTi-R with Fusion 3071 turbo, 800cc injectors, Q45 MAF, Front mount intercooler, forged engine, 2.5 inch exhaust etc. Tested on a dyno dynamics rolling road using SHOOT_44 dyno mode. Could have got more, but clutch is near its limit. Looking good I'm quite pleased.
Results: 418bhp@ 7250 rpm 1.5bar boost. 380lb/ft @ 5250. 328bhp @ wheels. 310ish lb @ wheels. Q45 MAF tops out (about 417HP / 310rwkw)
RB30ET with GTR injectors, Current result is about 215rwkw @ 9psi. Michael found that factory RB30ET MAF peaks out at 190-200rwkw on this run. He is getting a Z32 MAF which can measure up to about 320rwkw.
