Couple hundred miles covered in the Twingo and it's like falling in love with a loved one all over again. I have to say, of the 3 RS' I have owned, this one drives the best by far. The red one was fine, just high mileage, didn't have the cup pack and felt a bit worn, the blue one was definitely what I would classify as a project, had a constant engine tick, rough around the edges visually and had non stock springs (H&R springs which were 25mm lower than standard) which made it ride pretty harshly and polybushed engine mounts, which whilst a good upgrade over stock, do introduce vibrations.
This one though, drives so smooth, the idle is absolutely perfect, the gearbox is smooth, especially the 1st to 2nd change which can be crunchy in these and riding on the cup setup with the standard cup springs rather than H&R lowering springs, not only rides better but I think actually handles fractionally better as well. The KTec exhaust is fruity but not annoying, it doesn't drone when cruising but roars when you open up.
I think if I could combine that with a less restrictive air-box there are definitely a few extra horses that can be released. Even a 172 phase 1 air-box jammed in can find around 5hp, which doesn't sound like a lot but when you only have 131 to start with. The Sprogley Motorsports closed induction kit which includes a cold air feed and is designed specifically for the Twingo RS, allegedly offers a dyno proven 11.4bhp gain (about a 9% increase) vs the standard setup, and that doesn't factor in the exhaust, although the gains there would have been marginal (3-5bhp at most). The Sprogley kit costs a cool £300 however, so not an immediate purchase by any means. But being able to take power up to around the 143-145bhp range and torque from the 118lb-ft to around 132lb-ft.
But that's all long term, in the short term my priorities are the cup spoiler, which needs to be sprayed, fixings for the mats inside need to be replaced, headlights need a buff and there's a strange buzzing noise coming from somewhere around the wheels that increases with speed, could just be the spacers vibrating as they don't seem to be very good and 10mm spacers generally aren't hub centric which, unless they are put on to machine precision, means they can introduce enough vibration to buzz, or it's a gearbox mount or a wheel bearing, both of which are relatively cheap fixes (£25 parts) and should be easy enough to sort out.
Hopefully I will be able to take it to modified live at Snetterton in August.
Edit: it's wheel bearing. Renault tech father in law came over to have a look and after literally 15 seconds of driving it was diagnosed. He'll take it in next week to sort, parts are cheap it's just a bit of a faff to do apparently.
First minor dent into the Sprogley induction kit fund.
