Got owned by a few car lenghts last night by a BMW 320Ci, i dont usually race infact it was my first Fast and furious race since being on p's for over a year, but that BMW was riced up with 20inch mags and hektic exhaust and i knew it has the same amount of cylinder and engine capacity of 2.5 liters......So when i went to foor him on captain cooks bridge i was surprised a stock BMW which on paper has 170hp compared to 197hp skyline flogged me, i was in triptronic shifting at about 6-7 revs, we both started from 30k's i backed off at 100 he was already ahead so i gave up, speed limit was 80 so only 20 k' over i wasnt doing life risking racing btw all straight and not a soul on the bridge at that time.

i dont think its "underperforming", its most likely on the back of a tow truck

so what if 2 motors have the same compacity doesnt mean they will have the same power/ torque, or run the same rods/pistons crank etc, or the same bore & stroke or valve train cams, or even gear ratios diff ratio, tyres etc

your a p plater, and regardless of where it was or how much other traffic there was u shouldnt be racing anywhere thats not a controlled enviroment, otherwise other P platers like myself have to cop the bullshit extra laws they keep adding on because of you and others like minded

Yeah bro, chuck it on a dyno, will solve all your problems. Dunno if you know, but new model dynos have special sensors that are put in your exhaust, helps permanently suck out more exhaust gas. More air out = mor air and fuel in = more powarrrr...

Lol jks seriously though, running your car in a dyno isn't gonna do shit. All itll tell you is your car is making 150-170hp at the wheels... And by the sounds of it (youve described nothing mechanical at all, just winged about how you got beaten by a BMW.) there isn't anything real wrong with your car so a dyno run is wasted money. It's a non turbo skyline, they're not designed to be fast.

Save up and buy a GTT when you're off your p plates.

There is nothing wrong with giving your car a hit on straight line when there is no cars around............., i do a lot of freeway driving and i purpposely didnt exceed 100k's, the speed limit was 80....like i said im not going to crash at 100k's on a 80 zone, i have driven over that bridge 1000 times on the way home...

no such thing as safe speeding, regardless of how ever u feel the need to justify it, your a f**king tool, and even if you werent caught, you still have contributed to the extra bullshit laws the rest of the P platers who do the right thing all the time have to deal with

20km/h over thats what 4 points and a automatic 3 month suspension for a p plater in nsw?

I see, well the cars not perfect it sometimes shakes at idle im not sure why it happens but goes away and comes back, my mechanic suggested it needs new sparkplugs or coilovers, i used to driving my mates R34 manual around when he went holiday about once a week so it has someone to drive it around so the battery and stuff dont die, and it performs way better then mine, but that should be because its a manual and different gear ratio,my car feels like its got no grunt in 3rd or 4th so you could kind of figure out why im not sure its running like its supposed to, but you probaly right i just expect to much from it lol.

Im a good driver and i drive to the limit 95% of the time i need my car to get to UNI and Work, so im rarely recklessl, dont bullshit me man im sure you have gunned it past 10-20k's everybody has.

Famous last words! So many drivers - p-platers and fully licenced alike - have uttered those immortal words,

just before they wrote themselves, their passengers, or another motorist, out.

Non-turbo skylines are generally quite slow. I'm not surprised the BMW beat you to be honest. I'm sure everyone here has sped from time to time man maybe just don't tell everyone you had an illegal race.

      Thanks for the quick replies guys its appreciated. A small extension was welded onto the standard 6boost external gate pipe which you can see where the pipe goes from black to stainless just below and to the right of the rear housing in the first picture. Overall I would say the flow is pretty good other than 6boosts choice to come straight off the collector at a decent angle.. Not sure why I went with two valves, I originally replaced the stock twin bovs with the GFB when I had the twins on. When I purchased the EFR it came with the Turbosmart Kompact BOV so I figured that would be a better option than the stock EFR Bov. I don't believe the Turbosmart BOV is adjustable? When I get the spike and then sudden dip in boost pressure, the turbo speed does drop as well. Stock head size wise however I believe it has Neo Turbo springs and a Neo Turbo intake camshaft and an aftermarket exhaust camshaft in the vicinity of 260 degrees. We didn't try a different MAC valve, we tried two different ways of plumbing it and we also tried removing the mac valve entirely and just having the boost source from the turbo directly connected to the wastegate and it still spiked / dropped and exhibited the same behaviour. Standard R33 GTR 5 speed tansmission. I'm running a Haltech Elite 2500 and can provide some logs if you. I understand what you're saying in that it looks like an auto plot however no, it's still a manual and it just has a lot of torque down low, for all intents and purposes it's a very impressive street car. I've attached a photo of the quickbitz dyno plot which was when the only difference is I was running -5 twin turbos with a mac valve. As you can see theres a decent dip in AFRs between 125kmh and 135kmh. Our problem now is not that the AFRs are dropping, just the boost pressure is dropping, however it is evident in the same RPM range of the map, coincidentally or not.

      What transmission are you running?  It's a bit tricky with the scaling, but at face value the power "curve" looks more like a "line" which is a bit odd... basically a lot more like a dyno plot I'd expect with a highish (compared to a factory auto) stall torque converter type setup. If this is running an auto then this kind of boost control challenge is definitely a thing, the rpm scale on the dyno doesn't reflect what the engine is actually doing (unless the dyno has access to the engine's ACTUAL speed electronically) and what you'll get is a big rpm flare up as the engine torque launches past the converter pump's ability to resist torque at that rpm, then as the converter starts picking up rpm it will kinda even out again and the engine rpm will pick up more steadily. The trick with this "flare up" is if it's kinda near the boost threshold for the turbo then the engine's airflow requirements to maintain the previous boost level will outrun the turbo's ability to supply that boost - so you end up with a natural flattening off, if not dip when that happens.   If you are running closed loop, or even tune the "feed forward" wastegate duty cycle to deal with that rpm spike then when the engine starts settling to a more typical climb you'll actually have a situation where the gate is "too closed" and boost will run away for a bit, then have to pull down again.      It's not trivial to get this perfect as most boost control systems are generally expecting more predictable engine rpm rates of change, but if you *know* that's whats going on then you can at least "accept your fate" and realise getting that area perfect is kinda chasing your tail a bit, and assume that if the rest is working sensibly and the spike/dip isn't completely uncontrolled then you should be good. Sorry if I've gone off on a tangent, but the dyno plot and boost control behaviour look a LOT like what I've seen tuning autos in the past. What ECU are you running? Could possibly be convinced into looking at logs if I get too bored this weekend haha.

      A few things that seem a bit off here. - why is there 2 BOV’s?  - the turbo smart BOV on the compressor housing, is it turned up ALL the way? I have seen this become an issue on old man Pete’s car. It would push open and recirc, turbo speed would rise and the boost pressure would do weird things. - stock head? Does that include springs? - tried a different MAC valve? Is it plumbed correctly?
