ScottyZ Posted August 22, 2013 Posted August 22, 2013 Am I right in thinking that the maximum power that can be extracted from the 370 engine with all the aftermarket breather/exhaust mods,uprev remap - in fact anything APART from Forced Induction, is around 340 - 350 BHP at the CRANK. This figure is what mine is running at and also the new Nismo. Just curious. Cheers, Scotty Quote
Wasso Posted August 22, 2013 Posted August 22, 2013 (edited) Cams would make an improvement over that. I was reading last night a guy in America who's pushing 370-380. If you've got the cash to flash, anything is possible. Edited August 22, 2013 by Wasso Quote
oldbonesmcgee Posted January 29, 2014 Posted January 29, 2014 I thought cams weren't possible on the 370s VVEL system and even if they were the system is so good they wouldn't provide much gain anyway. Bear in mind the Ferrari Developed V8 4.2 in a Maserati GranTurismo only puts out 399hp, so 350hp from a 3.7 V6 developed by Nissan is still quite impressive. Obviously 370 would be the ultimate target though! Quote
brillomaster Posted January 29, 2014 Posted January 29, 2014 true but a ferrari developed 4.5 litre V8 in the 458 Italia puts out 562bhp, or 124.8 hp per litre what you need are engine components able to withstand a stratospheric rev limit (say, 9000rpm) combined with a high compression ratio and all airflow mods to get air in and out on time.... by ferrari logic the absolute max you could get from a 3.7 litre engine would be 462bhp, but to make that power there wouldnt be anything left of the original engine!

PS13Silvia Posted January 29, 2014 Posted January 29, 2014 I thought cams weren't possible on the 370s VVEL system and even if they were the system is so good they wouldn't provide much gain anyway. AFAIK that only applies to the intake cam. Our exhaust cams are just normal camshafts so can be changed, there's one aftermarket set I know of: Jun. All sorts of long winded threads on USA forums about them, which I've not read. The Jun product info is misleading IMO as they compare a stock car + exhaust to a built engine (higher compression CP pistons & CP rods as well as their exhaust cams) with larger injectors & different ECU plus the exhaust then claim those gains: http://www.junauto.co.jp/news/enews000163.html Either way, they look cool 1 Quote
PS13Silvia Posted January 29, 2014 Posted January 29, 2014 Stumbled across this while getting that Jun link, 5 pages of techy stuff to get your head round if you have the time: http://www.370z.com/MagazineArticles/tabid/57/articleType/ArticleView/articleId/57/Nissans-370Z-VQ37VHR-Cylinder-Head-and-VVEL-Continually-Variable-Cam-Timing-Technology-Technological-Terror-or-Performance-Breakthrough.aspx Quote

nissanman312 Posted May 3, 2014 Posted May 3, 2014 What sort of money for a good sc kit fitted by a pro? Quote
Darren-B Posted May 3, 2014 Posted May 3, 2014 FI is the way forward, mine is running nigh on 450 rwhp & is a dream 1 Quote
Dynamic Turtle Posted May 3, 2014 Posted May 3, 2014 Including supporting mods, probably about £10K? Very ouch. Quote

When you have £100k + cars that get smaller in you rear view mirror it makes it all worth it & if that's not enough, then the look on their faces when they pull up next to you after they have been owned by a Datsun makes it all worth it 😀 Edited May 3, 2014 by Darren-B 3 Quote

mike89 Posted May 7, 2014 Posted May 7, 2014 There is a guy where i live who i believe is on the forum (Chan) who told me his 370z is 380bhp. He has HFCs, invidia exhaust and stillen Gen3 intake and got it mapped in leeds somewhere. He said the guy that did it was surprised and its the best gains he has seen from those mods. Quote

That's probably what the RR told him, which is no ones fault as dyno's are only mapping tools TBH. One RR will read 380, another will read 360, depends on how they're calibrated amongst other things. Many a tuner war convo be had to this. It's all just pub talk anyway really. Quote

That'll be RS Tuning most likely. I believe their dyno is on the optimistic side by all accounts. Also, was that at the hubs or fly as that would obviously make quite a difference (17% IIRC after you take into account the power loss from the transmission). Quote
Richf Posted May 7, 2014 Posted May 7, 2014 (edited) Owners in the US have got 400hp with reworked intake manifolds, header pipes plus the usual mods , it's true it's expensive and time consuming to tune these and most n/a engines http://www.z1motorsports.com/g37_370z/product_info.php?cPath=597_804&products_id=7223 Edited May 7, 2014 by Richf Quote
oldbonesmcgee Posted May 13, 2014 Posted May 13, 2014 That is an interesting link, thats cheap! With some intakes, an exhaust, reworked intake and new manifolds you can get 400hp? It seems a little too good to be true! Quote

All the cars that come out there usually have reserved numbers unlike tdi norths dyno. Quote

Chan267 Posted June 9, 2014 Posted June 9, 2014 My car made 370bhp at rs tuning then 372bhp at ava rr but like most people said, its how the car drives that matters the most. Will get both 370z out and you can see for yourself the difference between the two. Quote

Will get both 370z out and you can see for yourself the difference between the two. I've got the Invidia Gemini and CNT/ERZ HFC's. Would be good to see the difference before I buy the Gen3 then pay for a remap. Talking another £1k Edited June 9, 2014 by mike89 Quote
