Dynamic Turtle

Tempted, but just wondering if all the fitting and balancing hassle is worth putting 3.5mm boots on the rear..

Used ds2500 and pagoda on the 350, brembos had good cold bite but 2500 were better for fast road/ track use, too much squeal with pagoda though, unbearable! Will look at the CL when I come to change the Nismo pads.

On another topic I think Haskins serves quite possibly the finest pizza I've ever had. Amazingly good canteen for a garden centre! A little bit of subsequent googling showed that they've hired no less than the head of catering at the park lane hilton to run the operation - and it shows. I'm making it a fixture on my south downs tours so look out for a black nismo in the same car park

Why not just put the Berks back on? Magic combination!

Had whitelines on my 350 front and back. On the hardest setting there was a frankly dangerous lack of grip, on the softest it was enough to make driving at 50mph a lot of fun.

True but the £40k premium you pay for the GTRN is probably going on more than fancy alloys and silent exhaust? Agree that it's defo S-line lifestlye addenda on the Juke and marginal proficiency gains on the 370 but they involve relatively limited financial outlay in both circumstances

Just waved, lovely car mate, bit quiet though!

Indeed, £37k just about gets you into an old GTR...

Oh and brake lines, awesome alloys and tyres and a bit of other tinkering plus all the options. I mean, how much can you expect for a £10k upgrade? Look at the difference in 330i and M3 (£20k), 911 and GT3 (£40k) GTR and Nismo (£40k). Huge mark ups in line with big changes.

My 2009 370 with the Stillen exhaust and uprev made 309 @ the hubs (and before Cosworth filters were fitted) which as the standard Nismo exhaust is much quieter (noting Sipar's need for some more noise) it is also down on power that is really disappointing for something that should be giving some useful increase in power with the Nismo label over the standard 370 output. Agreed, but don't forget a lot of the Nismo upgrades are suspension and aero related not just power (Euro5 noise limits designed for the most conservative of regimes).

I was running that combo on my 350z DE and it was a magic, quiet when you wanted, loud when you floor it!

Well, good gain at 7285rpm, better watch that needle! Might get uprevved at some point but no rush...

Huh? So pre uprev it should be 285? Seems very low? Transmission losses of 60hp (344bhp stock so I would have thought 310 at the hubs?). I know mark has uprevved a lot of these for GT Academy but surprised to hear it loses so much to the hubs. 27hp gain is good for hfc + cobra though and glad to hear the nuanced improvement. How's throttle response now? Can you blip the throttle more readily?

Sad but true, mostly a test of how little you care for you personal safety and driving license. I don't feel the 370 is fast until 130+ but maybe because others back off? Have a few mates with serious mahinery, on the twisties the exige s murders me and on the straights the GT3 zooms off...

Best colour for both 350 and 370, particularly with anthracite alloys.

A32 is great, very popular with bikers too. Been spending a lot of weekends hooning around the South Downs this summer, lovely part of the world with some beautiful villages inbetween.

Only three times in about a year and a half, but it does bug me when it happens. I got this WifI OBD dongle: http://www.amazon.co...yRankDescending And this app for my Ipad. https://itunes.apple...d652142348?mt=8 It diagnoses and clears the code within less than a minute, so pretty handy (P0430 - catalytic converter efficiency below threshold - or something like that). I find it happens when the car is cold and I rev it a bit enthusiastically As well as the uprev, there is also the option of the defoulers which apparently move the sensors further out from the airflow. Much cheaper than an uprev but I fancied seeing what Mark can do with a Nismo and some breathing mods Apparently the defoulers are part of the berk design but they can still trip the CEL? Anyway it hasn't appeared yet and I don't mind spending a minute or two clearing the code twice a year to save £400 odd quid uprevving. Very interesting to see what mark can do with your car though... Downloaded OBD app so thanks for that...

Thanks for sourcing these at short notice, albeit at a 10% premium. The fit is perfect so no issues there but the combo is absolutely brutal and not for the faint hearted :o

Sipar how often does the CEL appear? Have you got one of those blutooth OBD dongles to clear it?

Not a fan of vids because my only recording device is a mobile and that's hardly going to do it justice. Plenty of existing vids out there on t'internet with cars running similar configs, surely?

Hey guys just a quick update on the Berk HFC situation on my 2014 Nismo. Abbey fitted them on Saturday in just over 2 hours having struggled with a couple of seized bolts (which snapped a tool). Probably a good idea to leave this job well alone and let the pros do the work. Re config I’m also running Cosworth panels and a full Cobra exhaust and it was a very snug fit so no problems there. Cobra gaskets were also fine under visual inspection. Put about 150 miles on them over the weekend, mix of B-road, traffic and motorway. There is HFC rattle on start-up but this disappears within 15 seconds. First thing to note is holy sheet the car is now LOUD with the windows down. Driving under WOT the rasp effect is much more magnified and sudden compared to the Berk HFCs on my Miltek’d 350. You can still modulate the effect by accelerating gradually so the exhaust gas can escape under less pressured conditions, but you do have to be very ginger on the pedal. It is still noticeably louder inside the cabin under gentle load. Under WOT the sound is utterly mental, with a deafening rasp much more aggressive and sudden than the 350, it also lingers on higher up the rev range where the 350 was done by 5000rpm. One side effect is that it’s made the exhaust sound a bit resonant with a wop wop wop reverb rather than a smoother tone, but it’s not really an issue. There is obviously more boom at motorway speeds (at least, the existing boom from the Cobras on a slight incline at 2,500rpm in 6th is now magnified) but not unbearable and similar to 997 GT3 levels for reference. I personally love the HFCs and finally feel like I’m driving a 3.7 V6 and best of all it’s so noisy you can’t hear the horrid VQ37 induction whirr! Windows up the noise is obviously heavily attenuated but where’s the fun in that? Performance wise it’s probably a placebo effect (and the extra noise) but the car feels a bit faster. Bum dyno is notoriously inaccurate but….it did feel peppier. No CEL yet but Mark said it’s only a matter of time. I believe Uprev is the only permanent way to clear it but I’ve invested in a code-clearing OBD reader as a stop gap in case it makes a regular appearance. Not a cheap upgrade (£550 in total) but it’s finally turned the car into the snarling beast it should’ve been from the factory. Not sure about actual dB levels but my mobile recorded 91db inside the car under WOT so it should still be fine on track. Verdict: recommended but probably best mixed with quieter exhausts like Miltek, Akro and Invidias? With a Cobra it is properly mental, you have been warned!

Probably cost as much to make Concorde fly again and at least that would contain a more useful fare-paying payload!

It is an awesome bit of kit but remember that it's cold war nuke bomber tech which cannot be anything other than excruciatingly expensive to operate. Glad to have seen it pulling stunts at Farnborough, but it probably needs to rest in a museum before it falls out of the sky.

Exhuming this thread - will that OBD work with the 370Z ECU?

They do look great in red...
