Take the car to the drags again. If your terminal speed is up on last time then no drama.

No harm in having a safe tune, dyno's are only a tuning tool.

Looking at the graph against AFR can help tell you if there is more in it to extract of course, the final number is not important. It is the change in number and it's magnitude across the graph that indicates good things.

Don't get hung up on dyno comparisons, whats the point in having a peice of paper that says 200rwkw if someone can show you one with 170rwkw for the same type of car. A that car is faster and more powerfull where it shows up and where it counts, on the track.I lost count of the number of times I've seen it and the number of people who don't get it years ago.

Just don't sweat it mate.

Well written..i guess it the knowledge of knowing whether your car is running safe and giving you the HP you need. I too don't believe in number...just want my ride to be reliable with many years of joyride left in it. Cheers!

Wot he said above, i agree!! but in saying that every1 would want their car to be making as much pwr at the wheels as possible. I would be disapointed with that personally considering wots been done. Before i put on my pod and was still running standard boost i was making 183rwkws. on my 34 now i got safc2, 3" kakimoto, pod running 0.8 and i made just over 200. Id be getting a 2nd oppinion. Just book it in 4 a pwr run, for like $50 and if ur AFR's are looking crazy on the 2nd dyno get them to do a retune and see wot it gets then. :D

Sounds about right...

Mine's putting out 186 rwkw @ .8 bar on a safe tune with the following mods (also runs 13.9 down the strip @ 100mph on a crap 60ft):

Apexi pod filter

Power FC

Blitz EBC

Front pipe

High flow cat

Cat back zorst

... running standard SMIC and turbo though and wouldn't even contemplate boosting any higher than .8 bar without a turbo that can cope with it.

Cheers.

There seems to be a bit of a pattern here, a lot of the guys that are quoting higher boost levels are actually seeing less power. This seems to indicate that possibly other things need to be changed for it to be worth while running the car at such high boost levels.

I'm not saying this is conclusive, but there is such a thing as too much boost. I'd like to know what would happen with the same car with the boost wound down to more like 10 -12 psi. Perhaps the car is getting excessive knock or something?

Also I'm not sure what pressure the intake valves can take before they start to have trouble shutting, I've heard that this can sometimes be an issue.

Personally just from seeing cars on a dyno day, of the cars that were running high boost levels it was only the ones that were well soughted out that were pulling deacent figures, all others were dissapointed.

      "Cheap" bolt on turbo on RB25DET NEO

      @Kapr Haha yeah thats the one. I missed that you had a built up engine, I wouldn't want to run it on there either then. It was good in my situation just to replace the original turbo on a stock engine. @MBS206Yep definitely not a replacement for anything name brand

      It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.

      By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
