Need more power from my little 75

[Chavwagon]

Yesterday I bought my new little 75ps connect and I'm worried about parking on a piece of chewing gum or something as I don't think it has the power to pull back off of it. How can I get the most power from this little motor. It's got an intercooler and the rocker cover says dura DI. It reminds me of the escort vans power in fact I almost wrote this at the wheel. Any ideas where to start. Map, exhaust, induction kit or are there things to do first?? Cheers.

I can't believe it's that underpowered unless there's something wrong with it, so maybe best to give it a full service and see if it's any better
After that, you'll need to get it read for any fault codes

75ps TDDI are not the fasted vans, You could try blanking the EGR, fit a Focus airbox and decat the a remap should improve things.

sell it and get a 110 or a caddy tdi

How old is the van?

The 75ps is pretty slow, the brand new one l drove had no shove at all. A remap will give you a good improvement.

[Chavwagon]

Cheers, somebody else said about blanking the egr. It's a 2004. What's the difference between the 75, 90 and 110?

[doebag]

The difference is 20% more power over the lower model at each step up.

I have a 90PS model, and while it could not be described as a 'performance van' in the real world it means that it will happily cruise at 70MPH on all motorways all day without struggling on long inclines. And because you are not tempted to thrash the engine to get any meaningful performance from it, fuel consumption is a bit better.

[Chavwagon]

cool thanks. i read somewhere that an ecu upgrade from 75ps to 90ps was possible before a remap can anybody confirm this?

[Dakta]

I wouldn't bother, if you get a custom map it should be able to max out the hardware without any prior updates.

My 75ps van went to the local dyno today as I was working on a friends car so i cheekily stuck it on for a power run, and it scraped 118-120bhp across two runs, with a wheel figure of 99.

So, unless you're looking for 'lots' of power, then I don't think you need to do much. Though I'm probably going to look into a decat soon as the turbos a little bit laggy IMO.

What kind of map? No remappers have ever claimed this kind of power increase.

[Dakta]

I'm not exactly sure I follow by your phrasing, 'what kind'? Do you mean who did it?

I try not to claim too much in terms of power increases, in my last job I used to operate a dyno and even then it was just a tool to help me engineer the software more than to give the customer a number, but I put it on the rollers today just for curiosities sake really and that's what it got. Furthermore, the losses work out at 18%, now there's always a debate over losses, dyno dynamics tends to be around (not always but as a guideline) 16% and they tend to be quite brutal, so without taking a dyno print as absolute gospel, we aint far off. I'm not quoting 120bhp to boast of course, though I am happy

I think, looking back at it, I could go for a bit more torque - the clutch is ancient though, it wants doing first.

anyway - clicky


You can't really boast about 120bhp anyway, it's still nothing really!

My main point really is that you can go as far as the hardware can support without having to go through multiple ecu tune stages, a custom tune will take you as far as the hardware can support so you can get it all done in one go

I mean I've read 90 bhp is the standard remap for 75. Been a while since the last update. Not doubting your figures, just asking if it's some kind of aggressive map over the recommended limit.

[Dakta]

Haha it's not an aggressive map, it's what i'd call 'tickling it'. I appreciate you're not doubting my figures, I'm actually surprised they're considered quite high, in terms of gain over standard then yes, but remember - it's a GT15 frame turbo and we can push some all the way to nearly 150-160bhp (google mg rover l-series)

Now our turbo is smaller than these, so that kind of figure isn't going to happen - but the gulf isn't that big. anyway.

Be interested in this 'recommended limit' though. What is it, where does it come from? Or is it just a figure of speech

[mrtn]

Great info. Thanks. I'll keep an eye on it.

There's plenty of talk here about remaps in past threads.

I bought a 05 connect 75 few days ago myself and changing the airbox to the focus one makes quite a bit of difference along with the snorkel but id like a bit more power and was wondering does blanking the egr really do any difference?
