may do, unless I go before - need to fit this new thing first.
I feel this has been lacking even before I took my car down santa pod. It's not felt that strong high up the power range for ages...
which although It's still 71 bhp, I want the torque to continue for longer - as atm, holding out in gears is a waste of time.
quick question to most people with aftermarket exhaust... when you floor it - is your exhaust loud all the way to like 6000 rpm... as mine goes totally quiet after about 4500rpm atm - is this to do with this whole problem?

you don't need acess to the front towing eye...
and yes one of the guys (scott m) had problems with his green corsa as it was too low.
Thing I can't figure out - is, if my torque stayed flat like tim's is - even though his is flat at 150ish lb/ft of torque and mine's only 85ish lb/ft of torque - then when I'm working out approximate bhp figures for when I fix it they seem too high. The bloke who dyno'd my car said my torque was good for a 1.2.
Mine:
Tim's
Atm, my peak bhp was made with 70 ish lb/ft of torque at 5200 rpm... to produce 71bhp.
But if this problem made my line not drop off as much and so it's say more like 78lb/ft of torque at say 5600 rpm then my power would be 83 bhp?
Hmm, actually it's probably not wrong - it's probably more likely to only to be something like 75lb/ft of torque at 5500 rpm - which would give 78bhp...
Oh well, have to see...

to be fair it may have been set up for volvo's, so they may be able to adjust something for body kitted cars? dunno really.

hmm that top pic doesn't really make his car look low at all, I think his was lowered by 60mm?
they do have a little notch for the front bumper which is lower, but its the skirts I think they were having problems with.?

i dont, i was commenting about scotts, he has 16's btw.
rolling road couldnt be adjusted, the lower the car down onto it, it wasnt the ramp causing the problems, it was just the fact that the car was too low at the front and sides.

Just took my T reg 1.2 16v Sxi on the rollers at power engineering, this is year 1999 so in theory isn't one of the later sxi's (2000,2001)...
People have been saying they're maybe 65 or maybe 75 for ages... but had mine rr'd today and the bloke rolling roading it confirmed mine was a 75 bhp version - except today I was only putting out 71 bhp
the reason is, he said my air flow meter was not working correctly. So as I got past about 4000 RPM, it stopped pumping more fuel in and therefore is currently lacking power.
I've felt this for ages, but my dad just said I had simply got 'used to it' - also explains why I went so slow down santa pod and why, when I change from 3rd to 4th (so it drops to say 4.2k RPM) it feels like there's nothing there...
as you'll see from my power graph, it goes lovely up to 3700-3800rpm, then dips a bit, then starts leveling off before finally completely dropping off after 5000 rpm.
this is a 16v car, it should pull quite nicely to more than that.
So yes, they are 75 - but no mine isn't, yet... gotta get that sorted. I felt it used to be pretty nippy, and wasn't really any more. He also said its quite a common thing to go and it doesn't show up on the 'orange management light'
Was a good day at P.E today - tim + fad got some good results. and Kris-td's was bloody good 99 bhp and 132 lb/ft of toque!
mine was 71 BHP and 87 LB/ft of torque... tempted to fix this and the go back and make sure its all running ok.

should be able to tell lookign at the current at the AFM. easy way to check. swap it with someone elses

Sxi has a very close ratio gear box, so - accelerates quite fast compared to the GLS (my mate has one) - I used to beat him till my air flow meter went. I did wonder how he was pulling away from me?
Paul J
get your air flow meter sorted mate you will notice lots of diference i changed mine when i had an engine problem and made it a fir bit quicker make sure u go new tho.
are gls's 1.4 8v the same as the ls if so this could explain why i beet most off the line and is generaly faster down our local drag strip if you like. if any one knows it its called laker road in rochester kent. im usre plenty of you do.
