But it does interest me, considering the GTI is 197hp and 1360kg and the 325 is 1450kg and 205hp or thereabouts, I think it would be pretty even if ever there was a (perfectly legal) drag race...Anyone know any GTI owners??

Hi Alex I was surprised to hear of a road car hitting the limiter in 5th. So I calculated 139mph back to revs using rolling circumference of tyre, 5th gear ratio and final drive ratio. I got 6550rpm which I guess would be pretty close the expected limiter value of Z3 In this economy/enviromentally friendly era, it is rare to come across such a designed for performance set of gear ratios with the added bonus of a direct (1:1 ratio) top gear. Such design detail is one of the reasons we love BMWs |

Evo Magazine had a run-in MkV GTi on the rolling road for fuel testing, and stock it was putting out well in excess of the rated 200bhp (I can't remember the actual figure). Even if it was stock, the GTi has 144bhp/ton vs your 141bhp/ton. You'd have marginally better traction, but to be fair between both drivers a rolling start is what I'd use, which'd negate the traction issue. My money would be on the Golf. Edited by T.J. |

You're probably right T.J. I've driven both and although the GTI felt more lively and immediate when pressed, the BMW seems to cruise into the larger figures with ease. I would like to get my hands on the performance figures for the 325 though, of particular interest would be the standing quarter mile and the kilometre-I think these were in the earlier manuals for the E46 coupes am I right?

have a look at www.fastsaloons.com, they have a "compare and race" section where you can "race" various cars 0-60 and compare full tech specs and performance info |

That's a pretty good site Steve, thanks-Although I think they did a full road test in EVO a good while back, nothing on the site mentioning it though, and it's also been pulled from their 'the knowledge' section-B**tards!

Had a quick look at that fast saloons site. Not sure if its accuarate. 530d,
they say V6 turbo, and 8.9 seconds to 60. It's actually a straight 6 and only takes 8.0 seconds to 60. Dave I'd say the 325 would have a very good chance of beating a GTi in any type of race. |

Alex, fastsaloons.com definitely doesn't seem that accurate on the technical info side of things; it's an ambitious site none the less-I'll have to talk to T.J. about getting those figures from EVO or wherever else, I am nearly 100% positive 0-400 & standing km times were in the older owners manuals for the E46 coupe, I remember comparing them against other motors-

Not sure if all manufacturers do it but the figures they put out for 0-60 etc are based on the car + 2 male passengers + full tank of fuel, so you on your own and a half tank would be saving 100kg approx so you might better the factory times.

Also I'm pushing a little extra horsepower, have 18's plus 255's on the rear, it could take as much as half a second of the official accelerating times. And if I decided to go on a diet, chuck the spare wheel and tools...who knows!

I think Evo's Golf was running 210 bhp on Shell Optimax and closer to 220bhp on 105 Octane race fuel.

Dave The handbook with my 330 is actually for the 323, 328, etc. It does have standing km times in (but not terminal speed). I made a note of the times for you but left the piece of paper at home. From memory a 328 was in the region of 30-32 secs. I'd imagine that your 325 would be close but maybe slightly slower than a 328 (you've got the same power, but I think the 325 torque is slightly lower). |

Thanks Diarmuid, that time of 30-32 secs is interesting-The Golf GTI covers the quarter mile in 15.1sec and the 325 does it 15.4-They're pretty even at that stage so it's a matter of finding the standing km time for the Golf, and finally settling the score. I think it'll be the Golf's day in all fairness...

Just got a second look at the handbook. Standing km time for the e46 328Ci is down as 27.0, the 323Ci is 28.9. So much for my memory!

Jaysus that changes everything-Judging by your times the 325 is quicker over the standing km than the GTI, which takes 28.7sec. I assume the 325 would be slightly slower than the 328 over the KM, say 27.5-28 sec at the most. Thanks Diarmuid, cheered me up no end!
