Are you getting a torque steer on acceleration from standstill and trouble stopping it wanting to light up one wheel
It will light them up if i try but after that it doesn't seem to pull a great deal harder than it did before. Yes it revs higher but there's no step in the torque and no clear power band. Basically it feels a bit flat at times.

That looks absolutely stunning Tedward! As mentioned, that head is crying out for a cover...Ecosse do a nice carbon fibre one which would go with your airbox
They offered me one and I didn't want it.

Just noticed your strutbrace is off the car as well?
It gets in the way of work and doesn't do anything anyway.

The bay is looking cracking. Have you taken the engine cover off? Is that not risky?
It doesn't do anything and it's been off for the last 3 years...

Were there any issues with the radiator?
There is about 5mm between the radiator and airbox. I've seen Longmans cars with the radiator housing moved forwards to provide clearance. With the uprated engine mounts the engine doesn't move too much so it's not an issue. I'd be a bit concerned if the mounts weren't fitted though.

Does look good, but the main reason for it is the power, 'so if its feeling flat'...
#199: Re: Project sleeper Author: Edward, Location: In the garagePosted: Wed Mar 17, 2010 2:49 am ---- I'll post up the rolling road print later for you guys to analyse...
#200: Re: Project sleeper Author: jimmyfloydreturns, Location: SittingbournePosted: Wed Mar 17, 2010 3:20 am ---- Looks amazing Edward! I love how you have kept the whole car standard, same as what I would do Man I miss my GTi
So.... whats all this about disappointing power delivery?
#201: Re: Project sleeper Author: vanman_foci, Location: Barry, South WalesPosted: Wed Mar 17, 2010 4:33 am ---- I must say I have been watching this from the start and I love how it looks standard now
Bit gutted for you as you don't seem happy with it! Hope you sort it out soon.
#202: Re: Project sleeper Author: Seb, Location: Under your bedPosted: Wed Mar 17, 2010 4:59 am ---- I'd like to see the graph, whether the figures are accurate or not means nothing, I just want to see the shape, see if it looks like there's anything up with it.
#203: Re: Project sleeper Author: Edward, Location: In the garagePosted: Wed Mar 17, 2010 1:08 pm ---- One rolling road print out...
#204: Re: Project sleeper Author: Geoff, Location: Evesham, WorcestershirePosted: Wed Mar 17, 2010 1:27 pm ---- Thats a bit of kink at 4500rpm!
I've just had a look at the longmans spec:
Max power: 190bhp @ 6750rpm
Max torque: 170lb ft @ 5500rpm
From the impression from reading the above you don't seem totally happy. I would be interested in what the others say when they see the above graph.
#205: Re: Project sleeper Author: Mattie-RS, Location: A Track near you ;)Posted: Wed Mar 17, 2010 1:36 pm ---- is there a graph for air/fuel ratio??
#206: Re: Project sleeper Author: macj, Location: EssexPosted: Wed Mar 17, 2010 1:41 pm ---- Power curve is the wrong way and you should see at least another 10ft/lb of torque with those cams.
I need more time to study the graph but I think you have a torque curve issue. My only thoughts are that they have mapped it with 14.7lambda but have not fuelled it enough at the top of the rev range. The MOT test would not reach that sort of RPM. They also set the rev limiter too high in the RR session.
Give me a PM if you want to discuss it further

I'm quite underwhelmed by it to be honest. There is no mid range as such either, it pulls but doesn't feel quick. Looking at the before and after charts it appears to have less torque at 4500rpm than before.
It is fast higher up the rev range but it doesn't exactly blow your socks off.

Nope.

Which they would have to do in order to keep the cat working long term? I believe such cams dictate the need for richer mixtures but those and cats don't go together.
#209: Re: Project sleeper Author: Seb, Location: Under your bedPosted: Wed Mar 17, 2010 2:05 pm ---- It's a shame you're not so pleased with it Edward. After the time and effort that has gone into it
#210: Re: Project sleeper Author: SAB206, Location: North WestPosted: Wed Mar 17, 2010 2:53 pm ---- Work that's done looks very neatly done, I like the OEM subtle look of it all.
It's a shame you're a bit dissapointed with it, I once went out In Bonsons car, and that felt MUCH different to the power delivery of the 180. It did knock me and throw me back in the seat, even mid-range it packed quite a punch.
I'm with you on the RR results too, all of them are a bit peculiar, but your torque is showing VERY similar to that of a 180 (mines 154ibft 0, should it not 'theoretically' be somewhat higher?
