Hey, Does anyone know the best way of getting an extra 30bhp or so from my renault scenic, its a 2.0 16v petrol with about 140bhp (think its 136 but who's counting). But I don't want to break the bank £500-750, any ideas ??

Hello and Welcome to the Forums.

I would say the best way of upping your performance would be to buy the 2.0 Turbo version , eats fuel high insurance and nobody wants to buy them in the used market, Why you would need more power from an Family oriented vehicle I'm not sure, I'm sure it will cost £500 to uprate brakes suspension alone, Plus increase to your insurance premiums.

More power / turbo

Have thought about the turbo version but its money I am reluctant to spend as the scenic I have is good enough for what I do its just a little sluggish at times, I don't use it as a family vehicle, I use it for work and end up lugging all sorts round in it, just fancied a bit more power that’s all...

What age is it? Would be cheaper to change it for a turbo one I expect - as otto said. Does it have to be a scenic?

Go faster, more power -help my brakes don't work

Maybe it's just me getting cynical in my old age - but why do many drivers think they can increase the power output of an engine by bolting on a few cheap bits. Ask any specialist and he'she will tell you simply this - "if it ain't broke don't fix it" Turning and modding cars is an expensive business. No point in tweeking the engine if the brakes and suspension don't match. The easiest way to make a car go faster is to reduce its weight. Get rid of the uneccessary crud that lying around inside and join Weightwatchers.:rofl: :rofl:

more power now

It's a 1999 which is a V reg with about 45,000 on the clock but looking on autotrader and alike it’s only worth about £3500 as there are loads of RXE editions around.
One friend recommended changing the cams but am not sure sounds a bit excessive and I still want the reliability.
I might just get it a good service instead and buy the turbo version when it drops a bit in price :crazy: :)

Nos

Maybe a just a little bit OTT, as much as I would love the extra power and it would be fun to murder VW GTI drivers, I think those days are gone for me.
Good idea thoough ;)

Have you ever watched rallying or car racing - those guys tweek just about everything and guess what they have a team of expert mechanics chasing after them and even at that 30% fail to finish due to engine probs. Have you ever heard the expression "there's no such thing as a free lunch". It has to be acepted that any serious mods will affect fuel consumption and reliabilty. More power will put strains on all aspects of a vehicle (brakes, suspension, etc). It should also be noted - how much extra are you going to have to pay on your insurance premium.:p

With regards to NOS it isn't an ideal way to boost power your engine will be taking one hell of a pounding + 50hp of NOS will not make it 190 hp as the Nos will still ahve to mix in the combustion chamber with the air and fuel that has gone through all the so you will get on average 15 hp less. Cams are ok if you match them to a decent exhaust etc and it will affect the low down pull of the engine. There is no £500 mod to give more than 5-7 hp I am building a track Rocco and to get a 30 hp gain on that it is going to cost £1400 engine alone another 600 suspension, the list goes on. You will have to either buy a quicker car or even better spend £500 on a small light weight car just for you. Charade turbos good for 120bhp with small mods and no engine probs;)

More Power

I can see where everyone id coming from, I don't think NOS is a realistic option for me, I quite like my engine, I looked at K&N filters which give 5bhp and that’s a maybe but I think I may follow the general consensus on this one and leave alone, although a company called angel tuning recon they can get me 15% extra from a remap and not adversely affect the fuel consumption. Does anyone have a slightly more educated opinion on this??:confused:
In regards to insurance, well ive spent years being good and saving my no claims so I might as well take advantage of it...

I put a K&N airfilter and an Ecotek valve on my Lag I and it certainly seemed a lot more responsive,

15% seems optimistic most companies tend to stretch the real figures. You will not get 5bhp from a k&n alone 1 maybe 2 bhp and even superchips claim only upto 10bhp. the other company you speak of claim 21bhp for the same thing?.

Maybe I'm missing somthing here but in the world I live in there are only two ways to get more power out of an engine. Firstly make it more efficient and secondly burn more fuel. Do any of these suppliers give any figures for this criteria. They seem to natter on about improved BHP etc., without increased fuel consumption and has anyone ever tested their claims independently. Maybe they are just playing on th placebo effect.

more power

Yep they said 15%, I thought that was a little optimistic so I emailed them and they confirmed it by email.

Yeh but have there figures been validated by anyone - I would like to know how they measure changes in output apart from just driving it up the road.

They even recon on up to 40bhp more from Diesel...
Here is the Diesel link have a look...
http://www.angeltuning.co.uk/pdfs/engine/Renault.pdf
Large hp gains from a diesel or more likely due to the ecu being programed to run lean incase of poor grade fuel etc and most are now run but very efficiet turbos, so adding more fuel and air and increasing the boost from the turbo can have very big effects. It will thought as stated by another person this will effect fuel, efficiency and the life of the engine.
