#1: Destroyed by a Swift Sport Author: GTIjim, Location: LincolnPosted: Tue Jun 12, 2012 2:44 pm ---- Well, I wasnt hanging around today in my GTI as i pulled off the roundabout and onto the dual carrageway. Had a Suzuki Swift Sport ('60 plate) up my chuff so put my foot down. He went into the outside lane and went past with zero effort.
This leads me nicely into asking a question; my exhaust has two tiny holes, one near the rear lambda sensor and another at the cat-to-mid pipe join. The car seems a little flat and unresponsive, could these things really be causing a significant loss in torque and power?
Any thoughts?
Regards,
Jim

#3: Re: Destroyed by a Swift Sport Author: Dillon, Location: KentPosted: Tue Jun 12, 2012 2:57 pm ---- Sounds like you have a few more issues than a blowing exhaust...
#4: Re: Destroyed by a Swift Sport Author: troy, Location: llanelliPosted: Tue Jun 12, 2012 3:02 pm ---- new swit sports go really well, i work for suzuki and the new 60 plate onward ones are great.
#5: Re: Destroyed by a Swift Sport Author: GTIjim, Location: LincolnPosted: Tue Jun 12, 2012 3:04 pm ---- The main hole is on the 'boss' where the rear lambda screws in. Bizzarely, there is no noticable loss in fuel consumption?!?
The symptoms are accompanied by a ticking sound under heavy load but am fairly certain it isn't the renowned manifold rattle.

#6: Re: Destroyed by a Swift Sport Author: Dillon, Location: KentPosted: Tue Jun 12, 2012 3:06 pm ---- Ticking sound under hard acceleration like it is 'pinking'? I had this in mine had to run it 98 ron it ran a bit far advanced.
#7: Re: Destroyed by a Swift Sport Author: GTIjim, Location: LincolnPosted: Tue Jun 12, 2012 3:19 pm ---- Hmmmm, kinda. Ive also noticed in traffic, pull away from stationary in 1st but leave it in 1st (covering short distances in traffic) upto about 3.5-4k rpm then lift off to slow down creates a muffled 'popping' & 'banging' sound, like a race car/bike on over-run???

#9: Re: Destroyed by a Swift Sport Author: spike_202, Location: West midsPosted: Wed Jun 13, 2012 12:27 am ---- Im not suprised, Dont they have 134bhp any way? + it's alot newer car than yours also over time yours will have lost power.
#10: Re: Destroyed by a Swift Sport Author: meady, Location: basingstokePosted: Wed Jun 13, 2012 6:27 am ---- Must of been the driver because my old 206 would keep with a swift sport all day

Are you joking!? You'll blow your self to pieces, I've seen the way you drive you've got a heavy foot..

Really? Well the pedal doesn't move further than the stop on the bulkhead, maybe yours moved further?
A Swift Sport is a nippy car and I accept that age will be a factor but the Swifts have naff-all torque. The car has felt better (when I got it) and am pretty convinced this wouldnt have been the case should the car be fully serviceable.
Is anyone qualified enough to state whether a holed exhaust would reduce power and why?
Regards,
Jim
#16: Re: Destroyed by a Swift Sport Author: spike_202, Location: West midsPosted: Wed Jun 13, 2012 10:29 am ---- Gti's arnt quick by modern standards mate most low engined cars have around the 130-140 bhp Mark
I would just try a good service including plugs maybe a k&n panel filter cat back exhaust then you should see how it goes.
#17: Re: Destroyed by a Swift Sport Author: Dillon, Location: KentPosted: Wed Jun 13, 2012 10:33 am ---- Yes a holed exhaust will reduce the torque, get it seen to!
The swift comes in at around 125bhp and about 8.6 0-60 The GTI running well should do it in around 8, there wouldn't be much in it but if your car is not running right would make all the difference.
Edit forgot to add why the Exhaust reduces torque An N.A. engine uses the back pressure in the exhaust with out it you will loose some torque, just slapping a bigger exhaust on usually spells disaster unless you have done all you can to get more air into it. See some of the bodied projects to see what that entails I don't think they would have as much of a problem with the swift in the right gear Last edited by Dillon on Wed Jun 13, 2012 10:37 am; edited 1 time in total
#18: Re: Destroyed by a Swift Sport Author: Edward, Location: In the garagePosted: Wed Jun 13, 2012 10:35 am ---- The Swift shouldn't be faster than a GTi...so yours must be sick.
#19: Re: Destroyed by a Swift Sport Author: GTIjim, Location: LincolnPosted: Wed Jun 13, 2012 10:55 am ---- Thanks fellas. The car was serviced only 4 months ago, Bosch plugs used and K&N panel added. Been running ok until the last few weeks when I started noticing the ticking.....assuming it to be a manifold issue (thought id just leave it due to the hassle of changing it). The car isn't driven in anger very often, does a lot of miles on the A1, steady 70-75. I understand the popping/banging to be air entering the exhaust after lifting off, effectively sucking air in like a venturi effect.
Its definately the torque that is suffering, that response and 'instantaniousness' when pressing the throttle has gone. Once past 4.5k it seems ok-ish.

It's typically unburnt fuel hitting a hot exhaust pipe and then igniting, making a pop/burble.

That'll be it!!! I'm too short to press the pedal all the way to the stop, my prosthetic left arm can't feel the gear knob so miss shifts regularly and the ticking, popping and banging was from the factory round the corner!
Cheers guys, all sorted now!

Im not qualified but yes it would reduce power because it affects how efficiently the engine can get rid of the exhaust gas.
EDIT: I didnt realise there was a 2nd page
#26: Re: Destroyed by a Swift Sport Author: MrMorris, Location: Over that hill.Posted: Thu Jun 14, 2012 8:19 am ---- depends if the swift had the 5 speed box or the 6 speed to be honest.
but the swift is a new motor. 206 gti is old. bound to slow down abit over time and age. plus you got any extra weight in your car? (sub, pointless crap that just builds up lol).
should be more the same speed if the 206 gti was WELL maintained.
#27: Re: Destroyed by a Swift Sport Author: GTIjim, Location: LincolnPosted: Thu Jun 14, 2012 3:10 pm ---- Yesterday eve I patched up the tiny holes with exhaust building paste (at least all the ones I could find) and the ticking noise became notably quieter but not eradicated.
Strangely, today i filled up at my local Jet petrol station. Car is pulling much better and the ticking noise is definitely quieter but still present. You'd hardly believe the previous fill up was at Shell!!!
I can't convince myself that a different brand of fuel would lower the volume of the ticking noise......that concept is plain ridiculous. I do however accept it would improve performance.
If the rest of the car wasn't a nail i'd change the full exhaust!!! Good excuse to go buy a newer GTI!!!
