B) Hi Geea, No offence taken I'm not really interested in arguing over a couple of 10th or 100ths of a sec, as I said I used an accelerometer, it stores the last ten times, but their not downloadable and the best 0 -100 is 4.63, the slowest is 5.02. I'll post you the device registered post if you like, so long as you send it back. Any way I had the car back on Tim Slako's dyno this morning and after going through the centre muffler chop, then back to 2 nine inch hotdogs, I'm down from an initial 298 kW at the engine to 284, I thought the airbox would help. Anyway leaving my clinic now to go and pick it up with a mandrel bent twin 2.5 from the cat, through a stainless muffler into 2.5 twins back to the twin 2.25 standard rear muffler. The dyno showed 9lb of boost and perfect mixtures, so it must be the centre muffler hotdog replacement loosing the power, Ford centre muffler $345. Perth exhaust centre, stainless 2.5 setup $550, maybe the factory got it right in the first place. P.S I'm serious about sending the accelerometer.

56 Mainline, your cold airbox idea is ingenious, brings the midrange back nicely, the spare parts boss at my dealership had a look, smiled and took down the details to pass on to other XR owners. Taking the car back to Slako's 2 morrow to re-TUNE the APS chip. This may bring back my Bullsh*t 0-100 times. B)

Hey Hg Ag, I'm sure you are a nice guy. The times done in my car were measured with a "Bell accelerometer" which cost me $750, I concede they may lose a couple of 100ths of a sec for accuracy but both times the run was with half tank gas, octane booster, 18 degrees at night on the same dead flat surface. With the environment and all variables the same, the car lost time, both runs done in auto foot to the floor. If I was going to bullsh*t it would be a bigger woppa than a couple of tenths of a second. The things do 0-100 in 5.7 out of the box, or maybe my car is just quicker than yours.

Bullsh*t. That car with that configuration is not cabable of 0-100 in 4.63. Hg Ag, The times were done in my car and measured with an in car G accelerator which cost me $750 so I would assume that it is reasonably accurate. Quick times done on half a tank of fuel, 18 deg at night with octane booster, Slow times done with the same environmental variables. I don't think that theres much point bullsh*tting over a couple of tenths of a second. And even if the G device is not entirely accurate, e.g. a couple of tenths out, by changing the exhaust the car still suffered using the same device.

:D Hey 56mainline. I had a couple of 9inch hotdogs put into the system and cut the airbox then inserted the xr8 nozzle into the rubber coupling. Car sounds much better now and power has come back somewhat. I'm going to take it back to Slakos and have the unichip done again. Re the warranty fears some people have, my selling dealer (who shall remain nameless here) is aware of all the mods I've had done and couldn't give a toss. I'm booked in for a new diff next week, service manager knows the car makes 300 + kW and basically said good onya give me a drive, said he loved it, then mumbled some thing about Ford keeping a warranty eye on those fitting gearchargers to the new 4x4 V8 utes and doing 4 wheel burnouts. So as usual, "Going Ford Is The Going Thing". I'm going for a spin now ta ta. P.S Has anybody got any info on better valve springs?

Hey 56mainline. I chopped out my centre muffler and lost midrange, waste of money waste of power, loss of peace and quiet

Thanks Ian, I think I might just try the 2 hotdogs if that's the case. Anybody got any ideas on better valve springs, apparently the GT ones fit and are stronger?

I meant, Bang for Bucks, anway has anybody got any ideas re the exhaust, will a 3inch from the CAT back to the factory 2.25s with a couple of hotdogs effect the backpressure,oh the frustration of it all.

I bought my T in July03,it has 6500 klms on it now. I had a stage 1 APS unichip fitted by Tim Slako here in WA, it made a big difference. 0-100 4.6 sec, 400 metres 13.26, nothing else but a drilled airbox and k&n filter. Chopped out the centre muffler and turned it into a noisy dog and lost half a second. I'm going to try a three inch from the CAT back to where the system splits into 2 two and a quarters. Making 312 kW at the flywheel, all this talk of incapable fuel injector flow etc, very scary, I think I'll stop while I'm ahead. As far as warranty goes, the diff has a usual Ford period noise at 95klm (just like an EB XR6 I bought new in 92, anyway my dealer knows about the unichip and couldn't care less, I think attitude has a lot to do with warranty claims. Has anybody got any ideas re the exhaust without wasting $1500 for a 3 inch stainless that seems to offer very little extra power, that's not good bang for bucks in my book

. I took out the centre mufler and the car turned into a dog, lost half a second from 0-100 and nearly 1 sec ond over the 400metres. Have a unichip,stage one, drilled airbox and K&N filter. Used to get 0-100 in 4.63 & 400 metres, best, 13.23. Now I'm very disappointed and man what a drone. I'm going to try a three inch from the cat to where the system splits into 2x2 and a quarter and fit a couple of 9 inch hotdogs on Monday 3rd nov. Hope this brings back the midrange and the quiet. Leave well enough alone I reckon
