Regardless of how little financial sense it makes if £8k was trivial then sure I'd have got a 182 at 18. Yes it's amusing that he's paying 8k at 18 (I paid £1.4k at 19...) but if he thinks it's ok then fine.
The usual response is: "NA tuning is very expensive in terms of BHP/£ especially on the Renault F4R." Depending on whether your £8k comes from living at home, working full time at asda and parents paying for food/rent etc or whether it comes from "working for your Dad's company as an 'apprentice' for a 'director's son' salary" will probably dictate your attitude to mods. Regardless tuning is still expensive, power claims are often massively exaggerated by the likes of ebay tuning chips etc and in reality we're talking thousands and thousands of pounds to get, for example, 200 BHP.
* Have a search of the forum (or does that require £12 membership? Can't remember) as there are loads and loads of topics on "hw 2 get more pwr 4 cheap." The usual Induction Kits/cone filters are rather useless on the F4R engine and will actually
lose power due to heatsoak, so please don't get an IK or cone filter. You will also be labled as the usual clio teenager chav pikey boyracer tw*t if you do, and I imagine you wouldn't want that.
* Yes, a decat will fail a legitimate MOT. Some people just fit the CAT once a year, others get it MOT'd by a "mate" who will, by complete chance, forget to do an emissions test or calibrate the system wrong in order to generate a "pass" result.*
* Remaps probably are one of the better perfomance/£ products as the increased lower down torque is arguably far more noticeable and useable than another X BHP between 6900 and 7250 RPM.
* Don't forget accelleration is all about power:weight ratios, and weight (or rather the lack of it) is free. Reducing the weight by 10% is the same as increasing the power by 11%. In reality removing the interior won't save 100 odd KG, but to gain the equivilant in BHP would cost circa £1000.
+ If he has all this money why would you buy a 172? Why not a 197?
£8k could have come from two backgrounds as I see it. There is full time lad at the local Halfords with a brand new 200, quite clearly he has spent his entire salary on his car and doesn't have living expenses yet. OP could easily live with parents, work FT at asda and spend £3k on the car and £8k on insurance. If he has done this then flame away
Or his parents may be in a position where throwing away 8k a year is ok, but throwing away 16k (insurance & 197) when he does write it off and doesn't want to claim isn't an acceptable amount.
