nowhereboy Posted February 4, 2014 Share Posted February 4, 2014 I've done a quick search and can't seem to find anything about this, I appologise for the noobish question. I own a 04 DE engined 350Z, I know these aren't the most tuneable lumps in the world but I'm intrested in how much power can be squeezed out of it. With full exhaust, plentinum spacer, light flywheel, induction and a re-map, what sort of figures could be expected? Does anybody run similar mods? What power are you putting out?

glrnet Posted February 4, 2014 Share Posted February 4, 2014 300 is achievable, SMD saw 300 from his with much the same mods that you mention. I think most people will agree it's more about the improved throttle response than anything else. Quote Link to comment Share on other sites More sharing options...
Grundy Posted February 4, 2014 Share Posted February 4, 2014 Curious to this aswell, What if with that line up you had the Heads Ported and Polished, being 10 years old etc... Quote Link to comment Share on other sites More sharing options...
hensh65 Posted February 4, 2014 Share Posted February 4, 2014 I think the main factor would be how much is your car in particular putting out just now. All down to how well it has been looked after, if so then 300BHP is possible. Think they say 15 to 20BHP increase so would be tight. Quote Link to comment Share on other sites More sharing options...
Arran Posted February 4, 2014 Share Posted February 4, 2014 Mine mapped after abbey made just over 300 at the fly. 270 at wheels I had only silenced decats, plenum spacer and 06 airbox with hks filter. Then uprev'd Now I have dc headers, motordyne xyz and art pipes and a few other little bits. Once mapped again hope to see around 325ish. Ive also a lightweight flywheel but that only helps response 1 Quote Link to comment Share on other sites More sharing options...
r37 Posted February 4, 2014 Share Posted February 4, 2014 i made 312 at the fly with a wasso plenum, HFC's, exhaust and a remap. didnt bother with induction and just have a HKS filter. Quote Link to comment Share on other sites More sharing options...
Tommo79 Posted April 1, 2014 Share Posted April 1, 2014 I recently took my DE to TDI North for a Stage 1 upgrade, they got it up to 299.3bhp at flywheel, they said it was a strong motor mine, and that they don't often see gains this good from the DE. They did a Dyno run just after they fitted the mods before the rempa and it was about 280bhp then I think. 1 Quote Link to comment Share on other sites More sharing options...
GMballistic Posted April 1, 2014 Share Posted April 1, 2014 Have a look in the Dyno results thread nowhereboy. http://www.350z-uk.com/topic/23450-dyno-results-info-thread/ After my UpRev I got 293.4bhp from my 2003 DE which I'm pleased with. I have a H.Dev plenum spacer, Invidia Gemini exhaust system, Berks HFC's and a Stillen air induction kit. On the same day at Horsham Developments a similar modded Zed (2004 model DE) got around 280+bhp from his so it will vary from car to car. Also ambient temps/fuel/engine internal condition & the dyno used will all contribute to different figures. Quote Link to comment Share on other sites More sharing options...
Wasso Posted April 1, 2014 Share Posted April 1, 2014 Wasso spacer FTW 2 Quote Link to comment Share on other sites More sharing options...
wizurd Posted April 1, 2014 Share Posted April 1, 2014 Hey GM. Is that the fly or wheel bhp ? OP like others have said you can get very near or just over 300 with just a few mods. All cars are different though. I got 300 (calculated from the fly bhp) once I had my uprev with abbey. Getting a better exhaust system soon so might have another go at the figures lol.

Wish it was at the hubs though. Still great results for an 11 year old motor I think. Quote Link to comment Share on other sites More sharing options...
wizurd Posted April 1, 2014 Share Posted April 1, 2014 Lol I thought for a more you'd meant at the hubs! Lol Its a cracking result though ain't it. Quote Link to comment Share on other sites More sharing options...

If that was at the hubs bhp it would be better as it would probably equate to being around 330/340bhp at the fly then. Yeah I'm pleased with it and as you know the UpRev makes for a much more lively drive especially in the first few gears. Plus it can go over 155mph now if ever I go on the Autobahn.

Fluke Posted April 1, 2014 Share Posted April 1, 2014 Motordyne Plenum Spacer, K&N Typhoon CAI, Berk HFC's, Miltek Exhaust and uprev'd at TDI North saw 310 bhp from my 2003 350z. The biggest difference is the way the car rev's and pulls, great to drive before I Uprev'd - Bloody Fantastic to drive after. 1 Quote Link to comment Share on other sites More sharing options...

Yep mine was an 04 on 92k when it was upRev'd had standard airbox, plenum spacer, berks & milltek exhaust and made just under 300bhp I distincly remember texting Papa and going "ner ner ner " Sent from the golf club...

Keyser Posted April 2, 2014 Share Posted April 2, 2014 Curious to this aswell, What if with that line up you had the Heads Ported and Polished, being 10 years old etc... It will help if you have the valves reseated and the head skimmed at the same time We just put an engine in that had the head skimmed valves reseated (no porting) block was honed and new rings - really noticeable power improvement the torque is back all the way up the power band.

Dave-350 Posted April 2, 2014 Share Posted April 2, 2014 (edited) Its just a number... 270BHP vs 300BHP, in a straight line it will be **** all difference. Improve your driving skills on track if you want to see a massive difference in how the car performs. PS - 299BHP at the fly on my DE with the basic mods; Spacer, Remap, Kakimoto/Stillen/BERK exhaust setup.

Yea ^^ the upRev gives a really smooth torque curve all the way through to the redline, which is also increased! ^_^ Quote Link to comment Share on other sites More sharing options...

350zPhil Posted April 10, 2014 Share Posted April 10, 2014 I'm at 308 BHP are the fly with plenum spacer, full exhaust system, cosworth air filter, the lightened fly makes no difference on the dyno but I definatly notice the difference when driving the car. 1 Quote Link to comment Share on other sites More sharing options...

Just out of curiosity, as I personally would rather spend the money on chassis improvements to get the available power down properly BUT - how much off the top of your head does a job like that cost ?

cyberfella Posted April 15, 2014 Share Posted April 15, 2014 I have a 2004 DE and it made 307 BHP and 297 lbft this morning at TDI North after 5 pulls on the dyno and about an hour and a half of mapping. The mid range has gained 30 to 50 lbft which is the most impressive thing about it. So yes, 300+ BHP is possible, but not guaranteed according to the mapper. They can vary 30 BHP with the same mods on them. It's often down to how they've been looked after/driven. I guess I got lucky. Like any car, turbo or not, a remap is essential if you've "increased airflow" in any way whatsoever. Mine was running very lean and that has been corrected. Average mpg on the road not affected during normal driving / some use of cruise control on motorways. Still 23 - 32 mpg. I don't know about spirited driving yet, but I don't care either. fast = fuel. It'll be better than a turbo whatever it gets. 1 Quote Link to comment Share on other sites More sharing options...
