scottyp Posted August 31, 2012 Share Posted August 31, 2012 Hi, Considering getting HFC's fitted to my 2005 350z, but a bit hesitiant due to previous exhaust mods having screwed over previously decent cars (sports manifold on the Boxster turned it into a nightmare!) - is there anyone in the south west who would consider a meet to compare noises, performance differences? I'm in Taunton if that's a help. Thanks Scott Quote Link to comment Share on other sites More sharing options...
M13KYF Posted August 31, 2012 Share Posted August 31, 2012 its just a noise thing really Quote Link to comment Share on other sites More sharing options...
spursmaddave Posted August 31, 2012 Share Posted August 31, 2012 I have HFC's and I used to live in Taunton..... but I now live in Kent HFC's don't spoil anything on a Zed Quote Link to comment Share on other sites More sharing options...
scottyp Posted August 31, 2012 Author Share Posted August 31, 2012 Ah, typical Do they make much of a performance difference? Looking to make the engine feel a bit more lively in the mid range Quote Link to comment Share on other sites More sharing options...
spursmaddave Posted September 1, 2012 Share Posted September 1, 2012 Well I had an upRev done with standard airbox + cosworth filter, plenum spacer, HFCs + Milltek exhaust and was well over stock before and 300bhp after All that on a 2004 Zed on 100,000 miles They are mostly for noise though, they give a nice throaty tone I am sure there is a vid of a load of us pulling out of a layby in Wales I will have a look....

Looking to make the engine feel a bit more lively in the mid range In conjunction with an uprev you will gain more nidrange torque, without it I doubt it will achieve much other than the noise....

scottyp Posted September 1, 2012 Author Share Posted September 1, 2012 Got the uprev and an induction kit already, but would probably need it doing again after hfc's ;( Probably just me, but the car seems quite lazy in its power delivery been used to screaming n/a's and would like to make the z feel a bit more frisky Quote Link to comment Share on other sites More sharing options...
