Well as title says just got my 32 dyno'd for the first time other day at unigroup. really didnt know what to expect car is fairly stock bar: exhaust,fmic,pod,spitfires,cai,ss manifold,dump/front pipe and highflow cat. Now i was told car is running lean and as you can see there is a noticable power drop just after hitting 5500. I was told it can either be a air leak or faulty afm. any ideas at what else i should be looking at to rectify this and improve my ride

cheers

Graph looks pretty normal to me

Car looks pretty rich to me and seeing as you running standard ecu it seems fine. Air:fuel ratio going down to 10afr.

When car's are tuned they usually sit dead straight on 11.5-12.5afr (depending on how lean you want the tune to be)

Have a look on the stickie rb20 turbo upgrades ( http://www.skylinesaustralia.com/forums/Rb...no-t103095.html ) to compare dyno runs.

You sure you weren't told it's running rich?

That's incredibly rich. Heaps more torque to be gained by leaning that out. It's fine though. Not dangerous or anything. You're just wasting fuel and potential power. :D (And giving your plugs a hard time)

You have a stock ECU and have changed the exhaust and intake system. It's gone into a region of the fuel map which it wasn't designed to when it had stock parts on it. Time for a remap. ;)

thanks for the input guys. yes my mistake i meant rich. and yes it does use more fuel than normal. have been looking at a toshi remap for a bit now. just want to get some few parts here and there, then book him in, as im not looking for huge gains from this car.

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      I suppose that's true. Barring almost any situation, I'll never sell so what the market does is kind of irrelevant to me. It's possible I'd make most of my money back. That spreadsheet I mentioned? Maybe I could make back more than what the car's total costs thus far are, but the parts and all that is possibly a different story... Thanks for reading. It was certainly a good moment and just makes the ties to the car that much stronger. It's exciting that the option will be there to bring it over, however I have some plans with a shop that may end up keeping the car there longer, not sure. Coupled with the fact I want to move there and haven't solidified any path yet. So in a way, it feels like I'm in a limbo state that is uncertain; time will tell.

      No worries, everything worked out in the end. I just wanted to make the point that it doesn't matter where it comes from (I.E Australia), it can be broken or improperly built. I would still purchase from these companies in the future. B2R - Not certain how that finished, this was on a car I wired a few things and street tuned. I know the owner ended up shipping the motor back to Australia for investigation. Hopefully some of it is covered under warranty.  Turbosmart - I always pressure test everything that goes on my car. It's a habit from my career in oil and gas. I run two 40mm's and both had major leaks from the actuator to exhaust portion through the shaft. I returned both, they shipped me back two and one was leaking and the other had a 38mm top (40mm gate with 38mm actuator cap, no idea how that happens). Eventually after a lot of back and forth I found myself with two non-leaking gates. I believe this happens a lot more then people would like to believe but you would never know if you don't pressure test them prior to installation. Crank Motorsport - Issued a full refund and let me keep the seat rails. I turned them into scrap metal for other projects. GKTech - Shipped me out a replacement and asked that I modify it as per my idea and that they would do the same for a future revision. ATP - Can just needed a large shim to bolt up properly.  Haltech - They started an actual proper Beta channel for firmware's a few months back and stopped using the general public for testing. I'm now much happier.  Speedtek - f**k Speedtek. I would love to watch them burn.

      I've got a Turbosmart wastegate, ATP catch can, many GK Tech parts and Haltech everything. Everything's been perfect, sorry to hear your experience wasn't the same

      The only high-power RB I've personally seen go pop after running for all of an hour on a dyno was built by B2R, while being remotely tuned by B2R. The only wastegates I've ever had leak like a sieve, return, still leak, return and get shipped back the wrong ones were from Turbosmart. The only final drive that I've ever purchased that were unusable, twice... were from Speedtek. The only seat mounts that I've ever purchased that placed the seats in the door frame were from Crank Motorsport. The only poorly designed parts that I had the manufacturer confirm should have been designed as per what I mentioned were from GKTech. The only ECU I've had firmware updates consistently break things are Haltech. The only catch can I've purchased that didn't fit in its advertised spot was from ATP. So forth and so on... Moral of the story, doesn't matter where it's from. Do your research beforehand and stick with products and companies you've trusted in the past.    @joshuaho96 If you want it done right, do it yourself.

      Something coarse-ish. 180 is good.
