Hey Guys,

Had my car dyno on saturday, i made 148rwkw with a stock rb20det with exhaust and FMIC, on stock boost, the guys who dyno the car thought it was way to high so checked out the dyno setup which was correct.

Does this sound right? I have the rb20det in my silvia and didn't bother checking the turbo before it was on. Do you think it is a stock turbo?

yeh this sounds right.

standard they are suppose to come with 210ps so it does equal around what you have got. next get the turbo and computer done.

my cuz did the same mods as you and the turbo/computur pulled 200rwkw.

most things i've read on mods to the r32 rb20det say that with the mods you have and also a rechipped ECU running 14psi should get around the 160rwkw mark?? are you shaw it was kws not hp as thats about the same reading?? i've been told that a vg30 turbo could get that kind of result but also with higher psi and tuning???

210-215ps is around 160kw AT the Flywheel. Not rear wheels. :D

148rwkw (~200-210kw at the FLYwheel) with say 11-12psi (which is where it should be with an Exhaust) is around the mark.

With AFR's at 12:1 & a few more degree's of ignition timing mine made 152rwkw on 12psi. I would say your AFR's are not rich, which is bad as when you decide to pump more boost in the old fuel pump won't want to come to the party and you will lean out.

15psi only saw a 12rwkw increase as the turbo begins to heat the air more and runs out of efficiency.

With a tuned computer 170rwkw is around the maximum you will get.

200rwkw must have been a very optimistic high reading dyno. Most probably a Hub Dyno.

A turbo can only flow so many cfm's before it starts chopping and superheating the air.

What dyno was that 200rwkw pulled on? All bets are it wasn't ran in the correct shootout mode/temp sensor placed incorrectly or it was on a hub dyno. :D

Doesn't matter, Dyno's are only good as a base tuning tool.

Shootout mode tries to make it an even playing field.

My RB20 did 137 rwkw with turbo back exhaust, pod and R33 turbo on stock boost and everything else stock. A/F ratio was 13 and it had a slight misfire.

After upgrading the fuel system it went down to 130 rwkw and a healthy 11.3 fuel ratio and no misfire.

This was on DynoDynamics dyno in shootout mode at Unigroup.

I just fitted a wolf 3d along with a front mount, pump, full exhaust etc and rolled 152rwkw on a roller. I've had it on a hub a few times and the numbers are CONSIDERABLY higher. Without the dump it was showing 176 rwkws (yeah.. right). Car is heaps faster on the road. Just looking at turbo upgrades now.... I'd like a real 200 - 210 rwkws.

Off topic but hey. How are you finding the wolf 3D? Is it the V4 and did you get the plug and play version?

      R32 GTS (RB20DE) Injectors Replacement

      By joshuaho96 · Posted

      Reading through the engine service manual their advice is do a cylinder balance test. Unplug one injector at a time and see if the idle drops a consistent RPM. You can also do this using a Consult cable which is easier. They also call for unplugging the power transistor, then with the engine off and the fuel rail unhooked from the manifold verifying that you have good fuel flow (even injection, no dripping/leaks, etc) when you twist the CAS by hand. Also verify the spark by pulling the spark plugs and allowing the plugs to ground and turning the CAS by hand. I would also start doing the sensor checks and idle valve checks in service manual. Make sure the MAF tests reasonably, the intake air regulator is sane, etc. You may have to get new spark plugs.

      This sounds very old of me, however since buying the Tiguan shit box, my view on shit boxes have changed.

      M35 Brake caliper replacement

      By Waders360 · Posted

      I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way

      This coupled with 6-9 speed autos with ridiculously short gearing is why these modern shitbox cars always seem so fast off the line. If it wasn't for those things, Raptors would not seem fast. The problem we have is there is a driveability gap between a more gentle take off and a wheelspinning sideways launch. The difference between ankle flex required to achieve one and ankle flex required to achieve the other is about 0.5°.

      Yeah I think I'm also with the opposite here. It's 'hard to keep up with traffic' because in the real world I'm accelerating with 15% throttle and they are pinning it. It feels like I'm being an overt dickhead at anything above 15% throttle, so the car sounds like I'm being an overt dickhead to keep up with/get ahead of traffic when I'm really just trying to drive with traffic. There would be no issue 'keeping up with traffic' if we used the same level of throttle input/aggression to drive around. People really do just drive around with their foot nearly pinned in econoboxes.
