I've done a bit of a video comparison (which isn't the best place to start due to too many differing factors, I know).
The first video is zedx19's completely standard P2 6 (or rallye?), and the second video is my P1 GTI6 with Magnex catback & PiperX IK.

Video Here.

Now, I know I cocked up the 1st to 2nd gear change, but I timed the videos and mine is 0.2 seconds slower to 20, 0.4 seconds slower to 30, and when both cars have completed the first gear change, my car is 0.2 seconds slower in gear to 60. (overall it's about 1 second slower to 60!)



My question is, what could be causing it not to run at 100%? The only things I can think of, are either a stretched throttle cable meaning WOT isn't achieved, or a lambda playing up? But my MPG seems to be inline with what other 6's achieve (about 25-27mpg) so I doubt it's that, really...
Normally, I wouldn't really be bothered, but you can see there is a clear difference between the two cars (along with my terrible gear change) and mine was shot on a slight decline! On my private track of course.
Or is this just a case of some cars have stronger engines than others?

+1

I haven't came across a 6 that's quicker than mine either between a few mates that have 6's.

I give mine some shit but at the same time it's very well looked after.

Would that have happened over time, or after a Cambelt change? Last cambelt was done 30K ago at C.G cars in Leicester IIRC.

I'm not bothered about pub figures & 0-60 times etc, it just made me wonder if it's all running at 100%, or if something's not quite right.

That's an idea, yeah! Not too far from Driffield either...
Only thing is, there can be a lot of difference from rolling road to rolling road - some over read, some under read; so to get a good idea I'd have to take along another 6!

I m getting my 6 back on the road for spring and would mind a trip down to Z cars. Will let you know when I m heading there.

These are all good points! I haven't got any receipts to hand at the moment, as the car's in Driffield & I'm in Manchester, but if feels absolutely fine. It does still pull hard etc; I was just wondering if the difference in speed was anything simple that could be worn out & in need of replacement - it's never felt slow by any means! Also, having never driven another 6, I've no reference point, so was just interested to see how others perform.
The only reason I posted up this thread was purely because I've got a list of things I'm wanting to upgrade and replace... I'm certainly not going to go chasing power figures or anything, because I know how expensive N/A tuning can get (and for relatively small gains!)

I'll check out the Lambda, and have a poke around to see if anything's not quite right... but it could just be the fact that it's old, like you say Chris.

mjt, That sounds like a good idea, keep me posted

Ah, another factor! That's why I've taken the difference in the videos with a pinch of salt. I'm running 50 profiles, not sure on the first video though...
However, the smaller the profile, the quicker the acceleration would appear to be, no?

I've been looking at decats, actually - do you still have it? lol
Errm, it's semi-enclosed I think? Doesn't have the cold air feed on the end. Might try out a standard box with just a panel filter - I've never really felt a performance increase with induction kits, they just seem to make more noise!

I'll give it a good service to start with - it can only help matters!

mine is standard except Rich W pulleys and flywheel and does it in the standard 7secs but i think zedx19's is still quicker but doesn't really bother me. if it pulls well and runs nicely i wouldn't worry about it

I always wanted an old Mini! Never could find one that wasn't completely rotten though
Ah, never mind - They're relatively cheap anyway from what I've seen, I'll try one out.

Oh yeah, it runs fine! I was just unsure if there was anything simple worth checking that could be the cause - I'm not particularly bothered by it being slower

That's reassuring! I guess his is just a freakishly well built engine from the factory... Seems to happen a lot with RS Clios too - you get very strong ones and very weak ones amongst the average ones.

Well if you look after that like i'm sure you will mate, you won't have any big issues, when you planning on whipping it back down to Carl to do the belt? His prices are really good considering the quality of work he does!

Bought the lightened crankshaft pulley off him too!
Loved the photos you took of it anyway on cliosport website, looked fantastic! Just glad someone's going to keep looking after it!
