bradleykit Posted December 9, 2009 Share Posted December 9, 2009 Anyone know how much is it for fitting de-cat on the 350z? And how long is it gonna take? Thanks Brad Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted December 9, 2009 Share Posted December 9, 2009 tell you tomorrow when my HFC's go in. should take too long and depends on which garage you use and what they charge per hour. Quote Link to comment Share on other sites More sharing options...
Ian Posted December 9, 2009 Share Posted December 9, 2009 The last 2 times I've had them fitted they have cost me £50 If they have a ramp then I cant see it taking much more than an hour TBH Quote Link to comment Share on other sites More sharing options...
bradleykit Posted December 9, 2009 Author Share Posted December 9, 2009 thanks guys... will try to ask around the garages^^ Quote Link to comment Share on other sites More sharing options...
TADDY Posted December 9, 2009 Share Posted December 9, 2009 cost me £40 and took 35min as i timed him Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted December 9, 2009 Share Posted December 9, 2009 cost me about £50 i think, was all bundled with the other work in the total cost. Quote Link to comment Share on other sites More sharing options...
yokomo Posted December 9, 2009 Share Posted December 9, 2009 if your feeling brave ....http://www.autohow.tv/ looks pretty simple and i may give it a go once i get my hfc (long off ) Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted December 9, 2009 Share Posted December 9, 2009 its not difficult, would have done my own, but due to time constraints and not having enough extension bars; it was in the garage having stuff done was no biggie to get them to finish the job.

bradleykit Posted December 9, 2009 Author Share Posted December 9, 2009 Thanks for your help guys^^ Just got it done this afternoon in a garage near my hse for 40 pounds^^ Take about an hr or so... havent got a chance to test the result yet, coz i gota go out before they finish, and my bro. andrew (black 350z owner) pick up my z for me, and told me it pop a lot more now but not as loud as he thinks. Also the OEM cat is SHITTTTTTT!!!! (sry, if u like it) It weight a ton compare to my new japspeed silent de-cat. Anyway, gettin my car to abbey tomorrow morning and get it re-map. Hope i can get a gud result ^^ But what sort of gain do u think i m gonna get? My z is a 53 UK version, with japspeed silent de-cat and y-pipe, amuse R1 titan exhaust, blitz induction kit (or u think i will get a better gain with JWT popcharger?), and a skunks 2 5/8'' spacer.

rtbiscuit Posted December 9, 2009 Share Posted December 9, 2009 should see some good gains, probably not so much in the BHP front, but definitly in the torque Quote Link to comment Share on other sites More sharing options...

I have pretty much the same setup as you (well zorst is the same!) apart form I have headers so will be a good comparison. There is a thread somewhere, think its in Abbeys thread with a few of my charts, and I saw some pretty good bhp and torque numbers. If you have a search around there you may see mine.... in a bit of a sorry state! Quote Link to comment Share on other sites More sharing options...
bradleykit Posted December 10, 2009 Author Share Posted December 10, 2009 Got back from abbey today with a very happy result final lbft 1140.2 final Hp 268.7 And all the readings are at the hubs, so the flywheel figure is over 300bhp Thanks Mark from abbey.

bradleykit Posted December 11, 2009 Author Share Posted December 11, 2009 Indeed read it in the wrong section...its...246.4! Quote Link to comment Share on other sites More sharing options...
Mark@Abbey m/s Posted December 11, 2009 Share Posted December 11, 2009 The larger figure is the hub torque we then divide it by the effective final drive ratio to get a flywheel figure. Bradley , good to here your happy. enjoy. Car wasn,t to loud either with the de-cats fitted. 3FIDDYZ car with the headers fitted gives a little more midrange torque and a few more top end BHP , sounds a little different as well.

matth76 Posted January 3, 2010 Share Posted January 3, 2010 Got back from abbey today with a very happy result final lbft 1140.2 final Hp 268.7 And all the readings are at the hubs, so the flywheel figure is over 300bhp Thanks Mark from abbey. Very nice results. 268 wheel horse power at the hubs equates to ~319bhp at the fly (assuming 16% transmission losses: 319 * 0.84 = 268). I believe the HR 350's dyno at around 255-260 at the wheels so 310-320bhp at the flyw for your car seems very realistic. You may need to change the "303bhp" your sig The osiris uprev reflash seems to have very good results with bolt on mods. Quote Link to comment Share on other sites More sharing options...

Better just to quote hub figs! Not that I am complaining about mine being 325 @ the fly via your figs! Also Abbeys Dynos are at the Hub so more accurate than at the wheel Quote Link to comment Share on other sites More sharing options...

Which ones are decent. Im looking at dc sport ones. Yep they are decent well made ones from a relaible company! You still got the Japspeed manifold group buy in your footer that was all!! And yep you do need to put your old cats on at MOT speedy, not a hard job to do if you got a jack and some axle stands! Quote Link to comment Share on other sites More sharing options...
