Want More Midrange/torque Will I Need To Change Cars

[Stu9]

It's an 03 1.6 petrol focus....acceleration isn't to bad and if sitting at a steady speed isn't bad either, but going uphill and midrange is crap, will I need to go back diesel or can anything be done boost this thing. And before anyone says get a 1.8-2 in petrol, I'm going for cheaper rd tax too

If there's anything that can be done boost the 1.6 in the middle for pulling power I'd stick to it as it's otherwise a good car

Short of fitting a supercharger or turbocharcger, or increasing the capacity (all expensive options) there is very little you can do - most tuning options (remap/ inlet/ exhaust) mostly increase the top end (and usually with only a litte more power) often, at the expense of midrange power torque

you really need a turbodiesel - preferably 1.8+ on a Focus or 2.0L+ on a Mondeo and then get it remapped for outstanding midrange

Focus mk1 1.6L petrol -

Focus mk2 1.8L TDCI -

http://www.mybluefin.co.uk/curves/Focus18TDCi115ps.pdf

The stock 1.6 petrol has 160Nm of torque at about 4k, after the remap its 165 (only 5 more) the Mk2 Focus 1.8TDCI has 277Nm of torque (a great deal more than the 1.6 petrol/ over 100Nm!) remapped its just a little bit shy of 300Nm (296Nm) a lot of torque for a car of this size/weight

Remapping the 1.6L petrol only increases by 8Hp - and thats only above 4k (about 4k-5.5k) and practically no improvement below this

In contrast with the 1.8 turbodiesel (mk2 TDCI) the power and torque comes in earlier and extends wider -, apart from the wider power/ torque bands and the big torque increase, the power is also increased by 20hp with the (Superchips bluefin) remap

The petrol needs to be driven differently from the diesel, the petrol engine needs to be revved more, if you want to make progress you often need to change down, and redline the engine, the diesel is the opposite, better to use the midrange, in a higher gear than the petrol, often without changing down (or changing down less gears)

no point in revving the diesel past 4k, and the petrol needs to be revved 5.5k to make progress

Yea I know they need to be revved that's what I can't be arsed doing plus I end up using fuel.....like I said before, it was stupid fkn move I did getting petrol after having diesels for the 3-4 yrs. I know it's also pointless mapping a non turbo, no way I'd do it. I'll sell this and that's me finished with petrol for the time being

Petrol or diesel is down to personal preference. I cant stand diesels personally because I like a car that can rev, but I understand why some people prefer the diesels.

You can get the 1.6 to rev more freely and bog down less by changing the air intake panel from above and behind the grill for one off a 2.0 Auto and fitting a performance panel air filter. However if you don't like working an engine you may as well go diesel.

[Stu9]

I Know but like I said above, it'll just use more fuel doing that therefore defeating the purpose of having a smaller engine

I think I'm being sticking to diesel for the way I drive

It may be that you cant stand diesels because you like a car that likes to rev, but with the 1.6 Focus you have to rev it

Compared to a similar turbodiesel, the NA 1.6 is realatively gutless (with about half the torque) fitting a panel filter typically improves power by an isignificant 2hp, likewise changing the intake is not going to increase power by much, never mind the midrange torque

Superchips supplies power and torque graphs for the remap on the Focus 1.6 petrol, it would be nice to see figures for a K&N panel filter and the 2.0L auto intake - do you have any dynocharts/ figures?

[Stu9]

I don't remember saying I don't like diesels, I've always liked them, and as I've said before, I don't rev car's but you obviously didn't see that. Chipping or mapping a 1.6 in my opinion's a waste of money, as said twice above, I got it for economy but unfortunately it's not for me as miss the low torque of diesels

[Nighthawk]

I think he was talking about the person he was quoting so you obviously didn't see that lol

FOCA was referring to me. My main reason for not liking diesels is from other peoples experience on here and friends/family. I just prefer petrol engines as they suit my way of driving and my pocket. But like I said, I appreciate why people do like diesels. Just not for me.

It was years ago I did the conversion on a Mk 1 Focus and it certainly helped with the rev range as they always bogged down, especially on a hot day. It wasn't a huge change but was noticeable and of course I didn't Dyno test it as I don't have a Dyno. Power and torque would not have improved as the issue was with the rev range. Funnily though the 1.6 Mk2.5 I had until recently was great. Mid range it was fine and 5 up with all the luggage for 4 women and myself and body boards etc, didn't have a problem on the North Devon hills when on holiday. I never changed down once and still averaged 42mpg despite the speedo sitting at 80 for much of the time on the motorways.

I'll need to change and stick to diesel, and might go to vx as I've been offered one

Im not familiar with the Ford vx - is that a new model?

[Stu9]

Yes
